PROXY STATEMENT FOR

2013 ANNUAL MEETING OF STOCKHOLDERS

This Proxy Statement is furnished in connection with the solicitation of proxies on behalf of the Board of Directors of OncoGenex Pharmaceuticals, Inc., a Delaware corporation, for use at the Annual Meeting of Stockholders, or the Annual Meeting, to be held on May 24, 2013, at 9:00 a.m. local time, or at any adjournment or postponement of the Annual Meeting, for the purposes set forth in this proxy statement and in the accompanying Notice of Annual Meeting.

The Annual Meeting will be held on May 24, 2013 at the offices of Fenwick & West LLP, 1191 Second Avenue, 10th Floor, Seattle, Washington 98101. This Proxy Statement and accompanying proxy card will first be mailed on or about April 22, 2013 to all stockholders entitled to vote at the Annual Meeting.

Voting Rights

Only stockholders of record at the close of business on March 28, 2013, the record date, are entitled to notice of and to vote at the Annual Meeting and any adjournment or postponement of the Annual Meeting. At the close of business on March 28, 2013, we had 14,670,020 shares of common stock outstanding.

Each stockholder of record is entitled to one vote for each share of common stock held on the record date on all matters. Dissenters’ rights are not applicable to any of the matters being voted on.

All stockholders entitled to vote at the Annual Meeting may cumulate votes in the election of directors. With cumulative voting, each stockholder is entitled to as many votes as shall be equal to the number of votes that the stockholder would be entitled to cast for the election of directors multiplied by the number of directors to be elected by the stockholders, and each stockholder may cast all of his, her or its votes for a single director or may distribute them among the number to be voted for or for any two or more of them. No stockholder, however, will be entitled to cumulate votes unless the name of the candidate or candidates for whom the votes would be cast has been placed in nomination prior to voting, and such stockholder has given notice, at the Annual Meeting and prior to commencement of voting, of the stockholder’s intention to cumulate votes. Otherwise, the proxies solicited by the Board of Directors confer discretionary authority in the proxy holders to cumulate votes so as to elect the maximum number of nominees.

How to Vote Your Shares

YOUR VOTE IS IMPORTANT. Your shares can be voted at the Annual Meeting only if you are present in person or represented by proxy. Whether or not you expect to attend the Annual Meeting, please take the time to vote your proxy.

Stockholders of record, or “registered stockholders,” can vote by proxy in the following three ways:

1

Table of Contents

If your shares are held beneficially in “street” name through a nominee such as a financial institution, brokerage firm, or other holder of record, your vote is controlled by that institution, firm or holder. Your vote by proxy may also be cast by telephone or via the Internet, as well as by mail, if your financial institution or brokerage firm offers such voting alternatives. Please follow the specific instructions provided by your nominee on your voting instruction card.

Even if you have given your proxy, you still may vote in person if you attend the Annual Meeting. Please note, however, that if your shares are held beneficially through a bank, broker or other nominee and you wish to vote at the Annual Meeting, you must obtain a proxy issued in your name from the record holder. Should you wish to attend the Annual Meeting, directions to Fenwick & West LLP at 1191 Second Avenue, 10th Floor, Seattle, Washington 98101 can be found on its website at: http://www.fenwick.com/fenwickfocus/1.5.4.asp.

Voting of Proxies

All shares represented by a valid proxy received prior to the Annual Meeting will be voted, and, if you provide specific instructions, your shares will be voted as you instruct. If you sign your proxy card with no further instructions and do not hold your shares beneficially through a broker, bank or other nominee, your shares will be voted:

Revocability of Proxies

You may revoke or change any previously delivered proxy that does not state that it is irrevocable at any time before the Annual Meeting by delivering a written notice of revocation or another proxy with a later date to our Secretary at our headquarters at 1522—217th Place S.E., Suite 100, Bothell, Washington 98021. You may also revoke your proxy by attending the Annual Meeting and voting in person, although attendance at the Annual Meeting will not, by itself, revoke a proxy. If you hold shares in street name through a broker, bank or other nominee, you must contact that bank, broker or other nominee to revoke any prior voting instructions.

Quorum

The presence, in person or by proxy, of at least a majority of the shares of common stock outstanding on the record date will constitute a quorum. Both abstentions and broker non-votes are counted for the purpose of determining the presence of a quorum.

Votes Required to Approve Matters Presented at the Annual Meeting

Our directors are elected by a plurality of the votes of shares of common stock present in person or represented by proxy and entitled to vote at the Annual Meeting. Ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm and the approval of an amendment to our 2010 Performance Incentive Plan requires the affirmative vote of a majority of the shares of common stock properly cast at the Annual Meeting. The approval of each of the amendments to our certificate of incorporation requires the affirmative of the majority of the outstanding shares of common stock entitled to vote at the Annual Meeting.

Table of Contents

Broker Non-Votes

Banks, brokers or other nominees are entitled to vote shares held for a beneficial owner on “routine” matters without instructions from the beneficial owner of those shares. Absent instructions from the beneficial owner of such shares, a bank, broker or other nominee is not, however, entitled to vote shares held for a beneficial owner on certain “non-routine” matters. The election of our directors, the approval of an amendment to our 2010 Performance Incentive Plan and the approval of each of the amendments to our certificate of incorporation will each be treated as a non-routine matter. The ratification of the selection of Ernst & Young LLP as our independent public accounting firm will be treated as a routine matter, and, therefore, no broker non-votes are expected to exist with respect to this proposal.

If you hold your shares in street name, it is critical that you cast your vote if you want it to count on all matters to be decided at the Annual Meeting. If you hold your shares in street name and you do not instruct your bank, broker or other nominee how to vote in the election of directors, the approval of an amendment to our 2010 Performance Incentive Plan and the approval of each of the amendments to our certificate of incorporation, no votes will be cast on your behalf with respect to these proposals.

As noted above, broker non-votes are counted for purposes of determining whether or not a quorum exists for the transaction of business at the Annual Meeting. Broker non-votes, as well as abstentions from voting, will not, however, be treated as votes cast and, therefore, will have no effect on the election of directors, the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm or the approval of the amendment to our 2010 Performance Incentive Plan. Because approval of each of the amendments to our certificate of incorporation requires the affirmative vote of the majority of shares of common stock entitled to vote on the proposal, as opposed to shares cast at the Annual Meeting, broker non-votes and abstentions will have the effect of votes against each of the amendments to our certificate of incorporation.

Solicitation of Proxies

We have engaged The Proxy Advisory Group, LLC, to assist in the solicitation of proxies and provide related advice and informational support, for a services fee and the reimbursement of customary disbursements that, collectively, are not expected to exceed $15,000. We will bear the cost of soliciting proxies, including preparing, assembling, printing and mailing this Proxy Statement, the proxy card and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding in their names shares of common stock beneficially owned by others to forward to such beneficial owners. We may reimburse persons representing beneficial owners of common stock for their costs of forwarding solicitation materials to such beneficial owners. Original solicitation of proxies by mail may be supplemented by telephone, telegram, via the Internet or by personal solicitation by our directors, officers or other regular employees. No additional compensation will be paid to these individuals for such services.

Availability of Proxy Statement and Annual Report on Form 10-K

Our Proxy Statement and Annual Report on Form 10-K for the fiscal year ended December 31, 2012 are available at www.sec.gov and on our website at http://ir.oncogenex.com/financials.cfm. We have provided to each stockholder of record as of March 28, 2013 , a copy of our consolidated financial statements and related information, which are included in our Annual Report on Form 10-K for fiscal year 2012. We will mail without charge, upon written request, a copy of our Annual Report on Form 10-K for fiscal year 2012, including the consolidated financial statements, schedules and list of exhibits, and any particular exhibit specifically requested. Requests should be sent to: OncoGenex Pharmaceuticals, Inc., 1522—217th Place S.E., Suite 100, Bothell, Washington 98021, Attention: President.

BOARD OF DIRECTORS

General

Directors are elected at each annual stockholders meeting to hold office until the next annual meeting or until their successors are elected and have qualified. Currently, there are six members of the Board of Directors. The following table sets forth information with respect to our current directors. The ages of such persons are shown as of December 31, 2012.

The Board of Directors held a total of six meetings during fiscal year 2012. During fiscal year 2012, each of our incumbent directors attended at least 75 % of the aggregate of (i) the total number of meetings of the Board of Directors held during the period he or she was a director and (ii) the total number of meetings held by all committees on which the director served during the period he or she was a member.

Although we do not have a formal policy regarding attendance by directors at annual meetings of stockholders, we encourage directors to attend and, historically, most have done so. All of our current directors were in attendance at the 2012 annual meeting.

Pursuant to our Corporate Governance Guidelines, the Board of Directors is required to hold at least four regularly scheduled meetings each year. At least one of these meetings must include budgeting and long-term strategic planning. Each director is expected to attend no fewer than 75% of the total of all meetings of the Board of Directors and meetings of the committees on which he or she serves.

Set forth below are the names of, and information concerning, our current directors.

Stockholder Communication With the Board of Directors

Stockholders who are interested in communicating directly with members of the Board of Directors, or the Board of Directors as a group, may do so by writing directly to the member(s) c/o President, OncoGenex Pharmaceuticals, Inc., 1522—217th Place S.E., Suite 100, Bothell, Washington 98021. The President will promptly forward to the Board of Directors or the individually named directors all written communications received at the above address that the Secretary considers appropriate.

Related-Party Transactions Policy and Procedure

Our Audit Committee is responsible for reviewing and approving all related-party transactions and conflict of interest situations involving a principal stockholder, a member of the Board of Directors or senior management. Our Code of Conduct and Business Ethics requires our executive officers and directors to report any conflicts of interest with our interests to our Audit Committee, and generally prohibits our executive officers and directors from conflicts of interest with our interests. Waivers of our Code of Conduct and Business Ethics with respect to an executive officer or director may only be granted by the Board of Directors or, if permitted by NASDAQ and any other applicable stock exchange’s rules, our Nominating and Governance Committee. We do not have a specific policy concerning approval of transactions with stockholders who own more than five percent of our outstanding shares.

We have determined that there were no reportable related-party transactions in fiscal year 2012.

Board of Directors’ Committees

The Board of Directors has established separately designated Audit, Compensation and Nominating and Governance Committees to assist it in performing its responsibilities. The Board of Directors designates the members of these committees and the committee chairs annually, based on the recommendations of the Nominating and Governance Committee in consultation with the Chief Executive Officer and the Chairperson of the Board of Directors. The Nominating and Governance Committee reviews committee assignments from time to time and considers the rotation of committee chairpersons and members with a view towards balancing the benefits derived from the diversity of experience and viewpoints of the directors. The Board of Directors has adopted written charters for each of these committees, which are available on our website at http://ir.oncogenex.com under “Corporate Governance.” The chairperson of each committee develops the agenda for that committee and determines the frequency and length of committee meetings.

Audit Committee and Audit Committee Financial Expert

The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and is currently comprised of David Smith (Chairperson), Jack Goldstein, Martin Mattingly and Stewart Parker, each of whom the Board of Directors has determined satisfies the applicable SEC and NASDAQ independence requirements for audit committee members. The Board of Directors has also determined that Mr. Smith is an “audit committee financial expert,” as defined by the applicable rules of the SEC. The Audit Committee held six meetings during fiscal year 2012.

Audit Committee Responsibilities

The Audit Committee is responsible for, among other things:

Please see the sections entitled “Report of the Audit Committee” and “Proposal Two: Ratification of Appointment of Independent Registered Public Accounting Firm” for further matters related to the Audit Committee.

Table of Contents

Compensation Committee

The Compensation Committee currently consists of Neil Clendeninn (Chairperson), Jack Goldstein and Martin Mattingly, each of whom the Board of Directors has determined satisfies the applicable SEC and NASDAQ independence requirements. In addition, each member of the Compensation Committee has been determined to be an outside director under Section 162(m), of the Internal Revenue Code of 1986, as amended, or the Code, and a non-employee director under Rule 16b-3 as promulgated under the Exchange Act. The Compensation Committee reviews and recommends to the Board of Directors the compensation for our executive officers and our non-employee directors for their services as members of the Board of Directors. The Compensation Committee does not have any explicit authority to delegate its duties. The Compensation Committee held six meetings during fiscal year 2012.

In 2011, the Compensation Committee retained Radford, an Aon Consulting company, to provide a report summarizing relevant benchmark data relating to industry-appropriate peers and make recommendations regarding base salary, target total cash (base salary plus target cash incentives) and the amounts and terms of long-term equity incentive awards for our executives as well as to benchmark and make recommendations regarding the initial and annual cash retainer amounts for directors and chairpersons of the Board of Directors and the various committees, as well as the amounts and terms of initial and annual long-term equity incentive awards for directors. The Chief Executive Officer then made recommendations to the Compensation Committee regarding compensation levels for the directors, committee members and executive officers, excluding himself, based on Radford’s recommendations for each. The Compensation Committee, in turn, made recommendations to the Board of Directors regarding compensation levels effective January 1, 2012. A further detailed evaluation by Radford for the executive officers occurred in 2012 and the same process was followed for recommendations regarding compensation levels for the executive officers effective January 1, 2013. No work performed by Radford during fiscal year 2012 raised a conflict of interest.

Please see the sections entitled “Compensation Discussion and Analysis” and “Director Compensation” for further matters related to the Compensation Committee and director and executive officer compensation matters.

Nominating and Governance Committee

The Nominating and Governance Committee currently consists of Stewart Parker (Chairperson), Neil Clendeninn, Jack Goldstein and David Smith, each of whom the Board of Directors has determined satisfies the applicable SEC and NASDAQ independence requirements.

The Nominating and Governance Committee reviews, evaluates and proposes candidates for election to our Board of Directors, and considers any nominees properly recommended by stockholders. The Nominating and Governance Committee promotes the proper constitution of our Board of Directors in order to meet its fiduciary obligations to our stockholders, and oversees the establishment of, and compliance with, appropriate governance standards. The Nominating and Governance Committee held four meetings during fiscal year 2012.

Board of Directors Leadership Structure

Jack Goldstein, a non-employee independent director, has served as the Chairperson of the Board of Directors since March 2010. We do not currently have a policy mandating the separation of the roles of Chairperson and Chief Executive Officer. This allows the Board of Directors flexibility to determine whether the two roles should be combined or separated based on our needs and the Board of Directors’ assessment of its leadership from time to time. The Board of Directors, however, believes such separation is currently appropriate, as it enhances the accountability of the Chief Executive Officer to the Board of Directors and strengthens the independence of the Board of Directors from management. In addition, by separating these roles, Mr. Cormack can focus his efforts on running our business and managing the day-to-day challenges that we are faced with, while allowing the Board of Directors to benefit from Dr. Goldstein’s extensive experience as a director of various public companies. The Board of Directors believes Dr. Goldstein is best suited to be Chairperson of the Board of Directors because of his extensive experience as a senior executive and as a chair of biotechnology and pharmaceutical company Boards of Directors.

The Chairperson of the Board of Directors is responsible for managing the Board of Directors’ business, including setting the agenda (with the input of directors and management), facilitating communication among directors, presiding at meetings of the Board of Directors and stockholders, serving as chairperson at each regularly scheduled Board of Directors meeting and providing support and counsel to the Chief Executive Officer. Pursuant to our Corporate Governance Guidelines, the Board of Directors is free to choose the Chairperson of the Board of Directors in any manner that is in our best interests at the time. The Corporate Governance Guidelines identify a number of non-exclusive factors for the Board of Directors to consider in the selection process, including the current size of our business, the composition of the Board of Directors, the current candidates for the position, applicable regulations and our succession planning goals.

Board of Directors’ Role in Risk Oversight

Consistent with our leadership structure, our management is charged with the day-to-day management of risks that we face or may face and provides our Board of Directors with quarterly risk assessment and mitigation strategy updates, while our Board of Directors and its committees are responsible for oversight of risk management. The Audit Committee has responsibility for oversight of financial reporting related risks, including those related to our accounting, auditing and financial reporting practices. In addition, the Audit Committee annually reviews and assesses the adequacy of our risk management policies and procedures with regard to identifying our management of financial risks, reviews the quarterly updates on these risks that are received from management, and assesses the adequacy of management’s implementation of appropriate systems to mitigate and manage financial risks. Furthermore, under our Code of Business Conduct and Ethics, the Audit Committee is responsible for considering reports of conflicts of interest involving officers and directors. The Nominating and Governance Committee oversees corporate governance risks, including implementing procedures to ensure that the Board of Directors operates independently of management and without conflicts of interest. In addition, the Nominating and Governance Committee oversees compliance with our Code of Business Conduct and Ethics. The Compensation Committee oversees risks associated with our compensation policies, plans and practices. The Audit Committee, the Nominating and Governance Committee and the Compensation Committee each report to the Board of Directors regarding the foregoing matters, and the Board of Directors approves any changes in corporate policies, including those pertaining to risk management

The Board of Directors has also adopted a Whistle Blowing Policy, which provides a means by which concerns about actual and suspected violations of our Code of Business Conduct and Ethics and other public interest matters are to be reported. We recognize that individuals may not feel comfortable reporting a matter directly to the appropriate persons at the company and therefore the Whistle Blowing Policy provides a mechanism by which a person may report a matter to NASDAQ OMX Group Corporate Services, Inc., a third party retained by us. Under the policy, the Chairperson of the Audit Committee determines whether and, if so, how an investigation is to be conducted and, together with the full Audit Committee in certain instances, resolves reported violations. In all cases, a report of the outcome is to be made to the Board of Directors.

Risk Assessment of Compensation Programs

We have determined that our compensation policies, plans and practices are appropriately balanced and do not create risks that are reasonably likely to have a material adverse effect on our company. To make this determination, our management reviewed the compensation policies, plans and practices for our executive officers, as well as for all other employees. We assessed the following features of our compensation, plans and practices: design, payment methodology, potential payment volatility, relationship to our financial results, length of performance period, risk-mitigating features, performance measures and goals, oversight and controls, and plan features and values compared to market practices. Based on this review, we believe that our compensation policies, plans and practices do not create risks that are reasonably likely to have a material adverse effect on our company.

Director Nomination Process

Director Qualifications

Members of our Board of Directors must have broad experience and business acumen, a record of professional accomplishment in his or her field, and demonstrated honesty and integrity consistent with our values. In evaluating director nominees, the Nominating and Governance Committee considers a variety of factors, including, without limitation, the director nominee’s skills, expertise and experience, wisdom, integrity, the ability to make independent analytical inquiries, the ability to understand our business environment, the willingness to devote adequate time to Board of Directors duties, the interplay of the director nominee’s experience and skills with those of other directors, and the extent to which the director nominee would be a desirable addition to the Board of Directors and any committees of the Board of Directors. The Nominating and Governance Committee may also consider such other factors as it may deem are in the best interests of us and our stockholders. Additionally, in accordance with the applicable securities laws and NASDAQ requirements, a majority of the members of the Board of Directors must be “independent.” We do not have a policy regarding diversity, but the Nominating and Governance committee does and will continue to consider each candidate’s experiences and qualities as described above and how these experiences and qualities complement the diversity of the Board of Directors.

Identification of Nominees by the Board of Directors

The Nominating and Governance Committee identifies nominees by first determining the desired skills and experience of a new nominee based on the qualifications discussed above. The Nominating and Governance Committee will solicit names for possible candidates from other directors, our senior level executives and individuals personally known to the directors, as well as third-party search firms. The Nominating and Governance Committee evaluates all possible candidates, including individuals recommended by stockholders, using the same criteria.

PROPOSAL ONE:

ELECTION OF DIRECTORS

Nominees

The following persons are our 2013 director nominees, each of whom was recommended by the Nominating and Governance Committee and approved by the Board of Directors for nomination at the Annual Meeting:

Unless otherwise instructed, the proxy holders will vote the proxies received by them for the nominees named above. If a nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who is designated by the present Board of Directors to fill the vacancy. Each nominee has consented to being named in this Proxy Statement and to serve if elected. We do not expect that any nominee will be unable or decline to serve as a director. Each director is elected annually to serve until the next annual meeting of stockholders or until a successor has been duly elected and has qualified.

Our current directors are Neil Clendeninn, Scott Cormack, Jack Goldstein, Martin Mattingly, Stewart Parker and David Smith, all of whom served on the Board of Directors throughout 2012.

Biographies of our 2013 director nominees are located above under the heading “Board of Directors – General.”

Director Compensation Overview

The charter of the Compensation Committee provides that the Compensation Committee is to recommend to the Board of Directors matters related to director compensation. The director compensation package for non-employee directors consists of annual cash compensation and an award of restricted stock units and stock options exercisable to purchase shares of our common stock. None of our employees is entitled to receive compensation for service as a director. Our current director compensation policy was adopted in 2011, went into effect as of January 1, 2012, and is set forth below under the heading “Director Compensation Policy – 2012 Director Compensation”.

Peer Group Used for Benchmarking 2012 Compensation

Our management regularly reviews peer group data to determine whether total direct compensation and each component of the compensation package are approximately equal to the targeted 50th percentile for director compensation of our peer company list. Based on this review, management makes recommendations to the Compensation Committee that they deem necessary to align director compensation with the foregoing peer group target. The peer group companies are amended from time to time at the discretion of the Board of Directors.

Our most recent evaluation of peer group companies for purposes of establishing director compensation occurred in 2011, when we were establishing our director compensation policy for 2012. At that time, in consideration of our market capitalization and number of employees, the Compensation Committee recommended, and the Board of Directors approved, a peer group based on the following characteristics:

Table of Contents

Research and development spending, available cash and enterprise value were also examined as additional metrics to help determine appropriate peer companies.

Based on the foregoing criteria, and the recommendations of Radford, the Compensation Committee recommended, and the Board of Directors approved, the following peer group for purposes of establishing our current director compensation policy:

Director Compensation Policy

2012 Director Compensation

As part of its evaluation of compensation levels for the 2012 fiscal year, the Compensation Committee recommended and the Board of Directors approved the retention of Radford to review compensation levels of our independent directors and committee members. Radford is a provider of compensation market intelligence to the technology and life sciences industries. Radford was instructed to benchmark and make recommendations regarding the initial and annual retainer amounts for directors and chairpersons of the Board of Directors and the various committees, as well as the amounts and terms of initial and annual long-term equity incentive awards for directors. The Chief Executive Officer then made recommendations to the Compensation Committee regarding compensation levels for the directors, excluding himself, and committee members based on Radford’s recommendations for each. The Compensation Committee, in turn, made recommendations to the Board of Directors. In November 2011, the Board of Directors approved changes to the compensation for non-employee directors in connection with their service on the Board of Directors and its committees for the 2012 fiscal year consistent with Radford’s recommendations, as follows:

PROPOSAL TWO:

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2013. A representative of Ernst & Young LLP will be present at the Annual Meeting, will be given the opportunity to make a statement, if he or she desires, and will be available to respond to appropriate questions.

The Audit Committee has conditioned its appointment of Ernst & Young LLP as our independent registered public accounting firm upon the receipt of an affirmative vote of a majority of the shares properly cast at the Annual Meeting. Proxies solicited by management for which no specific direction is included will be voted “FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2013. In the event that the stockholders do not ratify the appointment of Ernst & Young LLP, the Audit Committee will reconsider its selection.

Fees Billed by Independent Registered Public Accounting Firm

The following is a summary of the fees billed by our independent registered public accounting firm for the fiscal years ended December 31, 2012 and December 31, 2011 for professional services rendered to us:

Audit Fees. Consists of fees billed for professional services rendered for the audit of our consolidated financial statements and review of the interim consolidated financial statements included in quarterly reports on Form 10-Q that are filed with the SEC.

Audit-Related Fees. Consists of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements, including accounting consultations and fees related to registration of securities.

Tax Fees. Consists of fees billed for professional services for tax compliance, tax advice and tax planning. These services include assistance related to state tax incentives.

All Other Fees. Consists of fees billed for all other non-audit services.

Policy on Audit Committee Pre-Approval of Audit Services and Permissible Non-Audit Services

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services performed by our independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. For audit services, our independent registered public accounting firm typically provides audit service detail in advance of the first quarter meeting of the Audit Committee, which outlines the scope of the audit and related audit fees. If agreed to by the Audit Committee, an engagement letter is formally accepted by the Audit Committee.

Table of Contents

For non-audit services, our senior management will submit from time to time to the Audit Committee for approval non-audit services that it recommends the Audit Committee engage our independent registered public accounting firm to provide for the fiscal year. Our senior management and our independent registered public accounting firm will each confirm to the Audit Committee that each non-audit service is permissible under all applicable legal requirements. A budget, estimating non-audit service spending for the fiscal year, will be provided to the Audit Committee along with the request. The Audit Committee must approve both permissible non-audit services and the budget for such services. The Audit Committee will be informed routinely as to the non-audit services actually provided by our independent registered public accounting firm pursuant to this pre-approval process.

For the 2011 and 2012 fiscal years, the Audit Committee approved all of the services provided by Ernst & Young LLP described above.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2013.

PROPOSAL THREE:

APPROVAL OF AN AMENDMENT TO OUR 2010 PERFORMANCE INCENTIVE PLAN

Our Board of Directors is asking our stockholders to approve an amendment, referred to in this Proxy Statement as the Amendment, to the 2010 Performance Incentive Plan, or the 2010 Plan, that will increase the total shares of common stock available for issuance under the 2010 Plan from 1,050,000 to 2,050,000. Subject to adjustments for our awards that are not exercised or that are cancelled or forfeited as set forth below, the increase of 1,000,000 shares represents approximately 7% of the 14,670,020 shares of common stock outstanding as of March 28, 2013. The Amendment will also increase the number of shares that may be issued pursuant to the exercise of “incentive stock options” during the term of the 2010 Plan to 2,050,000. The Amendment was unanimously approved by our Board of Directors on March 19, 2013 and requires stockholder approval. Of the 1,050,000 shares previously approved, only 53,799 remained available for grant as of March 28, 2013. As of March 28, 2013, the closing price of our common stock was $11.33 per share as reported on the NASDAQ Capital Market. If approved, we expect to use the additional authorized shares for continued periodic equity grants to employees, including executive officers, directors and consultants.

Description of the 2010 Plan

The following is a summary of the principal features of the 2010 Plan. This summary is qualified in its entirety by reference to the 2010 Plan as amended as described herein, which is attached as Appendix A to this Proxy Statement.

Purposes of the 2010 Plan. The purposes of the 2010 Plan are to enhance our ability and the ability of any parent or subsidiary corporation, whether now existing or hereafter created or acquired, which we refer to as an Affiliated Company, to attract and retain the services of officers, qualified employees, directors and outside consultants and service providers, upon whose judgment, initiative and efforts the successful conduct and development of our businesses largely depends, and to provide additional incentives to such persons to devote their utmost effort and skill to our advancement and betterment, by providing them an opportunity to participate in our ownership and thereby have an interest in our success and increased value that coincides with the financial interests of our stockholders.

Shares Reserved for Issuance. Assuming the Amendment is approved by the stockholders, we will be authorized to issue up to an aggregate of 2,050,000 shares of common stock pursuant to awards granted under the 2010 Plan. In addition, the 2010 Plan provides that if an option granted under any of our other equity compensation plans is outstanding on the date of stockholder approval of the 2010 Plan and such option subsequently terminates or expires in accordance with its terms, the shares underlying such option that remain unexercised and unissued at the time of termination or expiration will become available for grant or issuance under the 2010 Plan; provided, however, that not more than 2,050,000 shares of common stock may be issued pursuant to the exercise of options that are designated “incentive stock options”.

In the event that all or any portion of any shares underlying an award other than restricted shares granted under the 2010 Plan can no longer under any circumstances be exercised or purchased due to the forfeiture or cancellation of all or any portion of such award, the shares of common stock allocable to the unexercised or forfeited portion of such award will become available for grant or issuance under the 2010 Plan. In the event that all or any portion of any shares subject to an award other than restricted shares under the 2010 Plan are reacquired by us for any reason other than cancellation or forfeiture, the shares allocable to the reacquired portion of such award will not become available for grant or issuance under the 2010 Plan. In the event that restricted shares awarded under the 2010 Plan are reacquired by us, for any reason, the shares so reacquired will become available for grant or issuance under the 2010 Plan. Shares that are withheld to pay the exercise or purchase price of an award or to satisfy any tax withholding obligations in connection with an award, shares that are not issued or delivered as a result of the net settlement of an outstanding award and shares that are repurchased on the open market with the proceeds of an award exercise or purchase price will not be available again for grant and issuance under the 2010 Plan.

Additionally, the number of shares available for issuance under the 2010 Plan will be subject to adjustment in the event of a recapitalization, stock split, reverse stock split, combination of shares, reclassification, stock dividend, or other similar change in our capital structure.

Administration. The 2010 Plan is to be administered by an “Administrator,” which, under the 2010 Plan, shall be either the Board of Directors or a committee appointed by the Board of Directors, or the Chief Executive Officer to the extent permitted under applicable law. Subject to the provisions of the 2010 Plan, the Administrator has full authority to implement, administer and make all determinations necessary under the 2010 Plan. The 2010 Plan is administered by our Compensation Committee.

Subject to the terms and limitations expressly set forth in the 2010 Plan, the Compensation Committee or the Chief Executive Officer have the authority to (i) designate new employees of ours or an Affiliated Company to be the recipient of awards and (ii) determine the type of the equity award and the number of shares of common stock to be subject to such options, restricted stock units or restricted share awards.

16

Table of Contents

Subject to applicable law, the Board of Directors may from time to time alter, amend, suspend or terminate the 2010 Plan in such respects as the Board of Directors may deem advisable; provided, however, that no such alteration, amendment, suspension or termination shall be made that would substantially affect or impair the rights of any person under any outstanding award without his or her consent. Unless previously terminated by the Board of Directors, the 2010 Plan will terminate on March 23, 2020.

Eligibility. The 2010 Plan provides that awards may be granted to our employees, officers, directors, consultants, independent contractors and advisors or those of an Affiliated Company, as may be determined by the Administrator. Assuming the Amendment is approved by the stockholders, in no event may any individual be granted equity awards under the 2010 Plan for more than 1,050,000 shares of our common stock in any one calendar year.

The actual number of individuals who will receive awards under the 2010 Plan cannot be determined in advance because the Administrator has discretion to select the participants. Nevertheless, as of March 28, 2013, 9 of our officers and directors and approximately 40 other employees would be eligible to participate in the 2010 Plan.

Terms of Options. As discussed above, the Administrator determines many of the terms and conditions of awards granted under the 2010 Plan, including whether an option will be an “incentive stock option,” or ISO, or a “non-qualified stock option,” or NQSO. Each option is evidenced by an agreement in such form as the Administrator approves and is subject to the following conditions, which are described in further detail in the 2010 Plan:

Terms of Restricted Stock Awards. Each restricted share award is evidenced by a restricted stock purchase agreement in such form as the Administrator approves and is subject to the following conditions, which are described in further detail in the 2010 Plan:

17

Table of Contents

Terms of Restricted Stock Units. Each restricted stock unit award is evidenced by a restricted stock unit purchase agreement in such form as the Administrator approves and is subject to the following conditions, which are described in further detail in the 2010 Plan:

Change in Control. Under the 2010 Plan, the Administrator has the discretion to provide in each award agreement the terms and conditions with respect to a change in control that relate to the vesting of an award and the assumption of an award or issuance of comparable securities under an incentive program, and individual employment agreements may contain similar provisions. If the terms of an option or employment agreement provide for accelerated vesting in the event of a change in control, or to the extent that an option is vested and not yet exercised, the Administrator may provide for the purchase or exchange of each option for an amount of cash or other property. Outstanding unexercised options shall terminate and cease to be exercisable upon a change in control except to the extent that the options are assumed by the successor entity, or the parent of the successor entity, pursuant to the terms of the change in control transaction.

Section 162(m). In general, under Section 162(m) of the Code, income tax deductions of publicly-held corporations may be limited to the extent total compensation (including base salary, annual bonus, stock option exercises and non-qualified benefits paid) for specified executive officers exceeds $1 million in any one year. Under Section 162(m), however, the deduction limit does not apply to certain “performance-based compensation” established by an independent compensation committee which is adequately disclosed to, and approved by, stockholders. In particular, stock options will satisfy the “performance-based compensation” exception if the awards are made by a qualifying compensation committee, the underlying plan sets the maximum number of shares that can be granted to any person within a specified period and the compensation is based solely on an increase in the stock price after the grant date (in other words, the option exercise price is equal to or greater than the fair market value of the stock subject to the award on the grant date). To meet the maximum number of shares requirement, the 2010 Plan limits awards to individual participants as set forth below. Other awards granted under the 2010 Plan may qualify as “qualified performance-based compensation” for purposes of Section 162(m) if such awards are granted or vest upon pre-established objective performance goals based on one or more of the following business criteria:

18

Table of Contents

Notwithstanding satisfaction of any performance criteria described above, to the extent specified at the time of grant of an award, the number of shares of common stock or other benefits granted, issued, and/or vested under an award on account of satisfaction of performance criteria may be reduced by the Compensation Committee on the basis of such further considerations as the Compensation Committee in its sole discretion determines.

Summary of Federal Income Tax Consequences of the 2010 Plan

The following is a general summary as of the date of this Proxy Statement of the United States federal income tax consequences to us and to the participants in the 2010 Plan. The federal tax laws may change and the federal, state and local tax consequences for any participant will depend upon his or her individual circumstances. The summary does not purport to be complete and does not discuss the tax consequences arising in the context of the participant’s death or the income tax laws of any municipality, state or foreign country in which the participant’s income or gain may be taxable. Each participant has been, and is, encouraged to seek the advice of a qualified tax advisor regarding the tax consequences of participation in the 2010 Plan.

Incentive Stock Options. No taxable income will be recognized by a US optionee under the 2010 Plan upon either the grant or the exercise of an ISO. Instead, a taxable event will occur upon the sale or other disposition of the shares acquired upon exercise of an ISO, and the tax treatment of the gain or loss realized will depend on how long the shares were held before their sale or disposition. If a sale or other disposition of the shares received upon the exercise of an ISO occurs more than (i) one year after the date of exercise of the option and (ii) two years after the date of grant of the option, the holder will recognize long-term capital gain or loss at the time of sale equal to the full amount of the difference between the proceeds realized and the exercise price paid. Generally, any gain realized by a participant will be taxed as long-term capital gain and any loss sustained will be long-term capital loss, and we will not be entitled to a deduction in respect to such disposition. However, except in the event of death, if shares acquired by a participant upon the exercise of an incentive stock option are disposed of by such participant before the expiration of the statutory holding periods (i.e. a “disqualifying disposition”), such participant will be considered to have realized as compensation taxed as ordinary income in the year of such disposition an amount, not exceeding the gain realized on such disposition, equal to the difference between the exercise price and the fair market value of such shares on the date of exercise of such stock option. Generally, any gain recognized on the disposition in excess of the amount treated as compensation or any loss realized on the disposition will constitute capital gain or loss, respectively. If a participant makes a “disqualifying disposition,” generally in the fiscal year of such “disqualifying disposition” we will be allowed a deduction for federal income tax purposes in an amount equal to the compensation realized by such participant. The exercise of an ISO may result in an “adjustment” for purposes of the “alternative minimum tax.” Alternative minimum tax is imposed on an individual’s income only if the amount of the alternative minimum tax exceeds the individual’s regular tax for the year. For purposes of computing alternative minimum tax, the excess of the fair market value on the date of exercise of the shares received on exercise of an ISO over the exercise price paid is included in alternative minimum taxable income in the year the option is exercised. An optionee who is subject to alternative minimum tax in the year of exercise of an ISO may claim as a credit against the optionee’s regular tax liability in future years the amount of alternative minimum tax paid that is attributable to the exercise of the ISO. This credit is available in the first year following the year of exercise in which the optionee has regular tax liability.

Non-qualified Stock Options. No taxable income is recognized by an optionee upon the grant of an NQSO. Upon exercise, however, the optionee will recognize ordinary income in the amount by which the fair market value of the shares purchased, on the date of exercise, exceeds the exercise price paid for such shares. The income recognized by the optionee who is an employee will be subject to income tax withholding. We will be entitled to a tax deduction equal to the amount of ordinary income recognized by the optionee, provided that certain reporting requirements are satisfied. Upon the sale or disposition of shares acquired pursuant to the exercise of an NQSO, the difference between the proceeds realized and the optionee’s basis in the shares will be a capital gain or loss and will be treated as long-term capital gain or loss if the shares have been held for more than the applicable statutory holding period (which is currently more than one year for long-term capital gains).

Restricted Shares. In general, a taxable event will occur on each date the participant’s ownership rights vest (e.g., when our repurchase rights expire) as to the number of shares that vest on that date, and the holding period for capital gain purposes will not commence until the date the shares vest. The participant will recognize ordinary income on each date shares vest in an amount equal to the excess of the fair market value of such shares on that date over the amount paid for such shares. Any income recognized by a participant who is an employee will be subject to income tax withholding. We are entitled to a tax deduction in an amount equal to the ordinary income recognized by the participant. The participant’s basis in the shares will be equal to the purchase price, if any, increased by the amount of ordinary income recognized. If a Section 83(b) election is made within 30 days after the date of transfer, or if no repurchase rights are retained by us, then the participant will recognize ordinary income on the date of purchase in an amount equal to the excess of the fair market value of such shares on the date of purchase over the purchase price paid for such shares and this amount will be subject to income tax withholding.

19

Table of Contents

Restricted Stock Units. In general, no taxable income is realized upon the grant of a restricted stock unit award. The participant will generally include in ordinary income the fair market value of the award of stock at the time shares of stock are delivered to the participant or at the time the restricted stock unit vests. We generally will be entitled to a tax deduction at the time and in the amount that the participant recognizes ordinary income.

Tax Withholding. Under the 2010 Plan, we have the power to withhold, or require a participant to remit to us, an amount sufficient to satisfy federal, state, local or foreign withholding tax requirements with respect to any options exercised or restricted shares granted under the 2010 Plan. To the extent permissible under applicable tax, securities, and other laws, the Administrator may, in its sole discretion, permit a participant to satisfy an obligation to pay any tax to any governmental entity in respect of any option or restricted shares up to an amount determined on the basis of the lowest marginal tax rate applicable to such participant, in whole or in part, by (i) directing us to apply shares of common stock to which the participant is entitled as a result of the exercise of an option or as a result of the lapse of restrictions on restricted shares, or (ii) delivering to us shares of common stock owned by the participant.

New Plan Benefits. All awards to directors, executive officers, employees and consultants are made at the discretion of the Administrator. Therefore, the benefits and amounts that will be received or allocated under the 2010 Plan, as amended, are not determinable at this time.

Equity Compensation Plan Information. The following table sets forth information regarding our equity compensation plans as of December 31, 2012. The table does not include information with respect to shares we are proposing to add to the 2010 Plan in Proposal Three.

Vote Required

Approval of the Amendment will require the affirmative vote of the majority of shares properly cast upon the proposal at the Annual Meeting. Proxies solicited by management for which no specific direction is included will be voted “FOR” the approval of the amendment of the 2010 Plan.

PROPOSAL FOUR:

APPROVAL OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO ELIMINATE CUMULATIVE VOTING FOR THE ELECTION OF DIRECTORS

On March 19, 2013, our Board of Directors unanimously approved, subject to stockholder approval, an amendment to our certificate of incorporation to eliminate cumulative voting for the election of directors by removing Article X from our certificate of incorporation. The text of the proposed amendment is set forth on Appendix B to this Proxy Statement.

Our stockholders currently elect directors by a procedure called “cumulative voting.” Cumulative voting enables a stockholder to cumulate votes for the election of a nominee by casting a number of votes for such nominee equal to the number of directors to be elected multiplied by the number of votes to which the stockholder is entitled. The stockholder also may distribute his or her votes among two or more nominees on the same basis. This procedure allows a stockholder to cumulate his or her votes for one or more of the nominees for director, meaning that his or her votes may be cast for one or more of the nominees. For example, in an election of three directors, if a stockholder held one vote, the stockholder would have three votes. He or she could cast those three votes for one of the directors, or cast two votes for one director and one vote for another, or cast one vote for each of the three nominees.

Our Board of Directors believes this procedure is overly complicated to implement and seldom if ever used by stockholders and is no longer in the best interests of our company and our stockholders, particularly in view of our large number of stockholders and broad-based ownership. In addition, a stockholder or group of stockholders holding a relatively small number of shares that cumulatively votes its shares in an election of directors could elect one or more directors whose loyalty may primarily be to the minority group responsible for their election rather than to our company and all of our stockholders. Our Board of Directors believes that each director is responsible to, and should represent the interests of all stockholders as opposed to a minority stockholder group that may have special interests and goals inconsistent with those of the majority of stockholders. The election of directors who view themselves as representing a particular minority stockholder group could result in partisanship and discord on our Board of Directors, and may impair the ability of our directors to act in the best interests of our company and all of our stockholders.

Accordingly, our Board of Directors is proposing to eliminate cumulative voting by removing Article X of our certificate of incorporation. If this proposal is accepted by the stockholders, our directors will then be elected by plurality vote as provided by our bylaws, without the right to cumulate votes.

The elimination of cumulative voting might under certain circumstances render more difficult or discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our common shares or the removal of incumbent management. Neither management nor our Board of Directors is aware of any attempt by any stockholder to accumulate sufficient shares to obtain control of our company.

If the amendment is approved by the requisite vote of the stockholders, we will file an amended and restated certificate of incorporation with the Delaware Secretary of State as soon as reasonably practicable after the Annual Meeting. The amendment shall become effective upon filing with the Delaware Secretary of State.

Vote Required

Approval of the amendment to our certificate of incorporation will require the affirmative vote of the majority of the outstanding shares of common stock entitled to vote at the Annual Meeting. Proxies solicited by management for which no specific direction is included will be voted “for” the approval of the amendment.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE APPROVAL OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO ELIMINATE CUMULATIVE VOTING FOR THE ELECTION OF DIRECTORS.

PROPOSAL FIVE:

APPROVAL OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO INCREASE OUR AUTHORIZED SHARES OF COMMON STOCK

On March 19, 2013, our Board of Directors unanimously approved, subject to stockholder approval, an amendment to our certificate of incorporation to increase our authorized shares of common stock from 25,000,000 to 50,000,000 and to make a corresponding change to the number of authorized shares of capital stock. The text of the proposed amendment is set forth on Appendix B to this Proxy Statement.

We currently have a total of 30,000,000 shares of capital stock authorized under of certificate of incorporation, consisting of 25,000,000 shares of common stock and 5,000,000 shares of preferred stock. Our Board of Directors is asking our stockholders to approve an amendment that will increase the number of authorized shares of common stock from 25,000,000 to 50,000,000, and increase the number of authorized shares of all classes of stock from 30,000,000 to 55,000,000. The number of shares of authorized preferred stock would remain unchanged.

Our Board of Directors has determined that it would be in our best interests to increase the number of authorized shares of common stock in order to provide our company with the flexibility to pursue all finance and corporate opportunities involving our common stock, which may include private or public offerings of our equity securities, or to issue stock dividends, without the need to obtain additional stockholder approvals. There are currently no formal proposals or agreements that would require an increase in our authorized shares of common stock. Each additional authorized share of common stock would have the same rights and privileges as each share of currently authorized common stock.

As of March 28, 2013, 14,670,020 shares of common stock, $0.001 par value, were outstanding, leaving 9,819,166 shares of common stock available for issuance. As of December 31, 2012, we had reserved, pursuant to varies equity award plans, 1,265,857 shares of common stock, of which 804,781 were reserved for options currently outstanding and 461,076 were available for future option grants. Additionally, as of December 31, 2012, we had warrants outstanding to purchase 1,587,301 shares of common stock. We have no shares of preferred stock outstanding.

At present, our Board of Directors has no immediate plans, arrangements or understandings to issue the additional shares of common stock. However, it desires to have the shares available to provide additional flexibility to use our common stock for business and financial purposes in the future as well to have sufficient shares available to provide appropriate equity incentives for our employees.

The issuance of additional shares of common stock in the future will have the effect of diluting earnings per share, voting power and common shareholdings of stockholders. It could also have the effect of making it more difficult for a third party to acquire control of our company. The shares will be available for issuance by our Board of Directors for proper corporate purposes, including but not limited to, stock dividends, acquisitions, financings and equity compensation plans. Our management believes the increase in authorized share capital is in the best interests of our company and our stockholders and recommends that the stockholders approve the increase in authorized share capital.

If the amendment is approved by the requisite vote of the stockholders, we will file an amended and restated certificate of incorporation with the Delaware Secretary of State as soon as reasonably practicable after the Annual Meeting. The amendment shall become effective upon filing with the Delaware Secretary of State.

Vote Required

Approval of the amendment to our certificate of incorporation will require the affirmative vote of the majority of the outstanding shares of common stock entitled to vote at the Annual Meeting. Proxies solicited by management for which no specific direction is included will be voted “for” the approval of the amendment.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE APPROVAL OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO INCREASE OUR AUTHORIZED SHARES OF COMMON STOCK.

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Objectives and Philosophy

Our executive compensation program is designed to:

To achieve these objectives we have established compensation programs that tie a substantial portion of each executive’s overall compensation to key strategic operational and financial goals such as the development of our product candidates, the establishment and maintenance of key strategic relationships, and the identification and advancement of additional product candidates. The Compensation Committee’s approach emphasizes the setting of compensation at levels the committee believes are competitive with executives in other companies of similar size and stage of development operating in the biotechnology industry while taking into account our relative performance and our own strategic goals. Our annual cash incentives and a portion of our longer term incentives, such as our performance-based equity awards, are tied to our achievement of corporate operating goals. We believe that successful execution against goals is the best way to enhance long-term stockholder value. Overall, our pay programs attempt to balance cash and equity to reward both short- and long-term performance.

Compensation Determination Process and the Role of Executive Officers in Compensation Decisions

The compensation review process was conducted subsequent to the end of the 2012 fiscal year in order to facilitate the comparison of corporate objectives against our full year performance. The Chief Executive Officer provided a presentation regarding our current compensation philosophies and programs to the Compensation Committee with the remaining members of the Board of Directors invited to attend. Typically, the Chief Executive Officer produces an executive compensation review for each Named Executive Officer, excluding the Chief Executive Officer, which includes recommendations for:

The Chief Executive Officer may also recommend other changes to an executive’s compensation package, such as changes in the executive’s eligibility for cash incentives. The Compensation Committee evaluates and, if determined appropriate or advisable, revises the Chief Executive Officer’s recommendations and forwards its own recommendations to the Board of Directors, which may in turn suggest further revisions.

The Compensation Committee also meets in executive sessions without the Chief Executive Officer present to discuss the Chief Executive Officer’s compensation, including base salary, year-end cash incentive award and annual stock option grant, and to make recommendations regarding such compensation to the Board of Directors. The Board of Directors considers the Compensation Committee’s recommendations with respect to the Chief Executive Officer in executive session and provides feedback to the Compensation Committee. With the exception of executive sessions of the Compensation Committee and the Board of Directors to review, recommend and approve the Chief Executive Officer’s compensation, the Chief Executive Officer is generally present at all deliberations of the Compensation Committee and the Board of Directors related to executive compensation.

During the fourth quarter of the fiscal year, the Chief Executive Officer recommends to the Compensation Committee the corporate objectives to be adopted under the terms of the STIP for the upcoming year. The Compensation Committee evaluates and may revise the Chief Executive Officer’s recommendations and forwards its own recommendations to the Board of Directors, which may in turn suggest further revisions.

The Compensation Committee makes final determinations with respect to the award of cash incentives under the STIP and all annual equity awards. The Board of Directors, after reviewing the recommendations of the Compensation Committee, makes final determinations with respect to the cash incentives to the executive officers and the Chief Executive Officer, as well as the corporate

objectives under the STIP. From time to time at the request of the Compensation Committee, members of our executive management team, including representatives from finance, legal and human resources, may provide information to the Compensation Committee and attend all or a portion of certain of the committee’s meetings.

Benchmarking of Executive Compensation

Every year or at the direction of the Compensation Committee, our management reviews peer group data to determine whether total direct compensation and each component of the compensation package are approximately equal to the targeted 50th percentile for executive officer compensation of our peer group. The peer group companies are amended from time to time at the discretion of the Board of Directors and based on Radford recommendations. In 2011, Radford was retained to review compensation levels and executive agreements of our executive officers and to provide a report summarizing relevant benchmark data and making recommendations as to executive compensation levels. Radford’s review included benchmarking the base salary, target total cash (base salary plus target cash incentives) and long-term incentives of our executives with industry-appropriate peers based on the following characteristics:

In addition, Radford also examined research and development spending, cash on-hand and enterprise value as additional metrics to help determine appropriate peer companies.

The peer group recommended by Radford in 2011 and approved by the Compensation Committee and the Board of Directors for the evaluation of compensation levels for the 2012 fiscal year, after a comprehensive review, analysis and discussion regarding Radford’s recommendations, is comprised of the companies set forth below.

Benchmarking in the Context of Our Other Executive Compensation Principles

In establishing executive compensation, the Compensation Committee focuses on a range around the 50th percentile of peer group benchmarking for each of base salary, target total cash (base salary plus target cash incentives) and long-term incentives for each similarly situated executive, which the Compensation Committee believes provides the tools to allow a company of our size to attract, compete for and retain the type of executives necessary for us to our achieve our goals but conserve our cash and equity as much as possible.

The Compensation Committee realizes, however, that using a peer benchmark is neither the only means for gathering and validating market data nor the only criteria for establishing executive pay. In instances where an executive officer is uniquely critical to our success, the Compensation Committee may provide compensation in excess of the benchmark. Upward or downward variations for base salary and long-term incentives may also occur as a result of the individual’s experience level, the balance of the individual’s different elements of compensation, market factors and other strategic considerations, which we refer to below as compensation factors. Additional market surveys, such as the Radford Global Life Sciences Survey, which reports compensation practices of a broad range of life science companies, are also utilized in determining market competitive compensation. The Compensation Committee believes that, given the competitiveness of our industry and our company culture, our base compensation, cash incentives and equity programs are flexible, reward the achievement of clearly defined corporate goals and are generally sufficient to retain our existing executive officers and to hire new executive officers when necessary.

Elements of Executive Compensation

We have designed and implemented compensation policies that have historically allowed us to recruit both in our geographic areas of operation (i.e., Seattle, Washington and Vancouver, British Columbia) and other areas. We seek to implement and utilize compensation policies that balance fixed and variable pay costs for a long-term, sustainable approach to talent acquisition and retention. Our executive compensation consists of base salary, cash incentives and stock option and RSU grants, each of which is discussed in detail below.

Base Salary

We provide an annual salary based on comparable market data for level of responsibility, expertise, skills, knowledge, experience, our unique organizational requirements and desire to maintain internal equity. When establishing executive compensation for 2012, the Compensation Committee focused on the respective peer group market survey as well as the Radford Global Life Sciences Survey for base salaries and incentive compensation. The executive base salary program targets a range around the 50th percentile of salaries for executives with the requisite skills in similar positions with similar responsibilities at comparable companies. In reviewing base salaries annually, the Compensation Committee also considers the role, overall value and contribution each executive makes to the achievement of our objectives. Executives may be compensated below or above that range based on the compensation factors described above. The Compensation Committee reviews base salaries in the first quarter of each year and may make adjustments from time to time to realign salaries with market levels after taking into account the compensation factors.

Cash Incentives

The STIP provides an annual opportunity for our Named Executive Officers to receive a discretionary cash bonus (stated as a percentage of each officer’s salary) based on performance related to corporate objectives established by the Board of Directors. The STIP, when combined with each executive’s base salary, is designed to provide total target cash compensation within a range around the 50th percentile of our peer group, subject to adjustment for the compensation factors described above. For any given year, these objectives may relate to operational, strategic or financial factors such as developing our product candidates, establishing and maintaining key strategic relationships, raising or maintaining certain levels of capital, improving our results of operations or increasing the price per share of our common stock. The Compensation Committee alone determines achievement level of corporate objectives as it relates to incentive compensation for executive officers. If corporate objectives are not achieved at a 100% level, the Compensation Committee may determine that the corporate objectives were not achieved or, in its sole discretion, may determine that such objectives were partially achieved. The Compensation Committee may award bonuses based on the foregoing determinations or, after considering market conditions, our financial position or other factors, the Compensation Committee may, in its sole discretion, determine not to award any bonuses or to award bonuses at less than maximum eligibility. Cash bonuses paid do not exceed the maximum eligibility amount.

Equity Awards

Our 2010 Performance Incentive Plan provides alternative forms of long-term incentives for our executive officers, including stock options with time-based vesting, which require the market value of our common stock to increase before they are valuable; performance-based RSUs, the right to which depends on successful completion of corporate performance goals; or RSUs with time-based vesting. We do not use a targeted split of cash and equity when setting compensation for our executive officers.

The number of stock options granted is discretionary and the value earned on any grant varies with the stock price over the option term. In large part due to the length of product development cycles, it is critical for our business to align the interests of executive officers and stockholders, and to retain executive officers by means of what we hope will be long-term wealth creation in the value of their stock options and RSUs, which have vesting provisions that encourage continued employment. We have historically elected to use stock options as the primary long-term equity incentive vehicle. Stock option grants are made at the commencement of employment, may be made annually and, occasionally, may be made following a significant change in job responsibilities or to meet other special objectives, including strategic goals and retention. Historically, annual stock option grants have generally occurred at or near the end of the year, as part of our annual evaluation of executive compensation, and are targeted around the 50th percentile of our peer group (in terms of market value), subject to adjustment for the compensation factors described above and the availability of equity under our equity-based compensation plans. Commencing in 2012, annual stock option grants occur subsequent to the filing of our annual report on Form 10-K for the most recently completed year. We expect to continue to use stock options as a long-term incentive vehicle because:

25

Table of Contents

Beginning in 2012, we awarded RSUs, including performance-based RSUs pursuant to the terms of our 2010 Performance Incentive Plan. Our decision to use RSUs for annual replenishment equity awards was based on a desire to reduce short-term dilution and stock plan share usage. RSUs provide the right to receive a specified number of shares of our common stock at no cost to the employee if the employee remains employed by us on the date the RSUs vest. The compensation value of RSUs does not depend solely on future stock price increases. While unvested, the value of RSUs provides a significant retention inventive and maintains alignment between the interests of stockholders and of management. Although its value may increase or decrease with changes in the stock price during the period before vesting, an RSU will have value in the long term, while the entire compensation value of a stock option depends on future stock price appreciation. Accordingly, RSUs can deliver significantly greater share-for-share compensation value at grant than stock options, and we can offer comparable compensation value with fewer shares and less dilution for our stockholders.

Stock Ownership Guidelines

Although stock option grants encourage equity ownership, we currently do not require our directors or executive officers to own a particular number of shares of our common stock. The Compensation Committee believes that stock and option holdings among our directors and executive officers are sufficient at this time to align this group’s interests with those of our stockholders.

Perquisites

Our executive officers located in Canada participate in the same group insurance and employee benefit plans as our other salaried employees in Canada and our executive officers located in the United States participate in the same group insurance and employee benefit plans as our other salaried employees in the United States. Tax preparation services are paid for executive officers who owe additional tax liabilities incurred by working in non-resident countries. At this time, we do not provide other special benefits or other perquisites to our executive officers.

2012 Officer Compensation

Salary

Scott Cormack became our Chief Executive Officer and President in 2008. Since 2008, the Board of Directors has successively increased his salary based on performance, which has brought his compensation more in line with the 50th percentile of peer public company chief executive officers. His leadership has driven our performance, leading our predecessor from its early start-up phase through development to proof of scientific concept in humans, the merger in 2008 that resulted in a public entity and the licensing of our lead product candidate. With respect to the 2012 fiscal year, based on Mr. Cormack’s instrumental role as our Chief Executive Officer in achieving our 2011 objectives, as well as a comprehensive review, analysis and discussion of the salaries of executives as reported by Radford Executive Compensation Report in 2011, Mr. Cormack’s base salary for 2012 was increased 3% to approximately CDN$520,150, which was consistent with the 50th percentile of the peer company survey, as converted to Canadian dollars, and warranted based on his performance and contribution to the achievement of company objectives.

Ms. Burris was our Chief Financial Officer from January 2011 to January 2013 and our Executive Vice President Operations from January 2011 to March 31, 2013. In determining her base salary for 2012, the Compensation Committee considered Ms. Burris’ extensive financial and operations management expertise as a public biotechnology company executive. Based on a comprehensive review, analysis and discussion of the salaries of executives in similar roles reported in the Radford Global Life Sciences Survey report, Ms. Burris’ base salary for 2012 was increased 3% and set at $375,950, which is approximately equal to 95% of the 50th percentile of the survey based on a combination of the survey data for the CFO/COO job descriptions. On March 31, 2013, Ms. Burris began serving as a consultant to our company, as which she will receive a monthly retainer of approximately $34,000 and will be eligible to receive an incentive payment of up to 40% of the aggregate amounts paid to Ms. Burris during the 2013 fiscal year, which will be based on a percentage according to our achievement of corporate objectives.

Dr. Cindy Jacobs is our Executive Vice President and Chief Medical Officer. In determining her base salary for 2012, the Compensation Committee considered Dr. Jacobs’ important role in furthering the development of our clinical assets and extensive experience in obtaining U.S. Food and Drug Administration approval for product candidates, as well as her instrumental role in partnering, alliance management and strategic discussions. Based on a comprehensive review, analysis and discussion of the salaries of executives as reported by Radford in 2011, Dr. Jacobs’ base salary for 2012 was increased 3% and set at $391,400, which is approximately equal to 105% of the 50th percentile of the peer company survey from 2011.

Table of Contents

During 2011 and until May 31, 2012, Cameron Lawrence served as our Principal Accounting Officer. In determining Mr. Lawrence’s base salary for 2012, the Compensation Committee took into account his finance and accounting background and his contributions to us in his role as Principal Accounting Officer. Based on a comprehensive review, analysis and discussion of the salaries as reported by Radford in 2011 and consistent with our compensation policies that allow us to recruit both in our geographic areas of operation (i.e., Seattle, Washington and Vancouver, British Columbia) and other areas, Mr. Lawrence’s base salary for 2012 was increased approximately 13% and was set at CDN$158,500, which was approximately equal to 95% of the 50^th percentile for financial executives.

Cash Incentives

In accordance with the Compensation Committee’s goal to target compensation around the 50th percentile of our peer group as described further in the section entitled “Benchmarking of Executive Compensation” and based on a comprehensive review, analysis and discussion of the recommendations set forth in the Radford report, the Compensation Committee recommended, and the Board of Directors approved, an increase in each Named Executive Officer’s bonus potential for 2012, as follows:

As a result, each Named Executive Officer’s bonus potential for 2012 was approximately equal to the 50th percentile of our peer group.

In the fourth quarter of 2011, the Board of Directors adopted the following 2012 corporate objectives under the STIP:

27

Table of Contents

The Board of Directors selected these particular corporate objectives based on its judgment that they represented areas over which the Named Executive Officers have significant operational control and on which the Board of Directors believed they should focus to move our strategic plan forward and enhance stockholder value during 2012.

Performance Against 2012 Corporate Objectives

The Compensation Committee determined that the corporate objectives for 2012 were achieved at the 90th percentile. This represented the Committee’s assessment that the first and second objectives were fully met but that the third was only partially met given that Borealis-1 accrued patients more slowly at its initiation than was originally anticipated. Accordingly, all persons eligible for a bonus under the STIP for 2012 were paid 90% of their 2012 bonus eligibility attributable to corporate objectives. Mr. Lawrence was not eligible to receive a bonus under the STIP as his employment with our company terminated as of May 31, 2012. For Mr. Cormack, Ms. Burris and Dr. Jacobs, 100% of their STIP eligibility was attributable to the achievement of the corporate objectives and, therefore, the final amount awarded to each is as set forth below:

Long-Term Incentive Awards

Stock option grants are discretionary based on the Compensation Committee’s analysis of employee achievement of company-wide and individual objectives. The Compensation Committee determined to award each Named Executive Officer non-qualified stock options to acquire shares of our common stock and RSUs pursuant to the terms and conditions of the 2010 Performance Incentive Plan. In each case, the Compensation Committee considered and evaluated the Radford report, the compensation factors described above and the amount of equity available for grant under our 2010 Performance Incentive Plan.

The number of stock options granted was calculated using an option grant dollar value (based on a Black-Scholes model) benchmarked to the 50th percentile based upon the comprehensive review conducted by Radford in 2011. Each option was granted with a 10-year term and an exercise price equal to the closing price of our common stock on NASDAQ on the date of grant. Consistent with the recommendations in the Radford report, vesting occurs monthly over four years, which represented a change from some of our prior practices of vesting stock option awards annually over four years.

The number of time-based RSUs and performance-based RSUs granted were calculated using a 30-day average stock price and a Black-Sholes value. Based on a comprehensive review, analysis and discussion of the equity awards reported in the Radford 2011 Report, the aggregate value of the time-based RSUs and performance-based RSUs granted to each Named Executive Officer, other than Cameron Lawrence, was benchmarked at the 75th percentile, with 50% of the total award consisting of time-based RSUs and 25% of the total award consisting of performance-based RSUs. The Compensation Committee determined the relative mix of time-based and performance-based RSUs was appropriate because such mix is consistent with our primary intent to retain our executive officers, while at the same time aligning long-term interests and encouraging long-term stockholder value. The time-based RSUs will vest annually over four years beginning on January 1, 2012. The performance-based RSUs will vest with respect to 100% of the award upon the achievement of both the successful enrollment and release of data from our Synergy trial and the completion of enrollment of our Borealis-1 trial.

Advisory Vote on Executive Compensation

In 2011, we held an advisory say-on-pay vote to approve the compensation of our executive officers, with approximately 98% of the votes cast in favor of our executive compensation program. In light of the support by our stockholders of our 2011 executive compensation program, the Compensation Committee has not made significant changes to our 2012 executive compensation program

In addition, at our 2011 annual meeting of stockholders, a majority of our stockholders voted in favor of an advisory vote on executive compensation every three years, and, accordingly, our Board of Directors determined that we will hold an advisory vote on executive compensation at our annual meeting of stockholders every three years. We expect to hold the next vote on executive compensation at the 2014 annual meeting of stockholders.

Other Policies and Considerations

Internal Pay Equity

The Compensation Committee reviewed the 2011 Radford report compensation and concluded that total compensation for a company’s chief executive officer is generally higher than the total compensation for either its chief financial officer or chief medical officer, and that the total compensation of the chief medical officer is generally higher than the total compensation of the chief financial officer. The relative total compensation for our executive officers for 2012 followed the same pattern observed in the Radford report, with our Chief Executive Officer receiving the highest total compensation, followed by our Chief Medical Officer and our Chief Financial Officer. Our ordinal pay ranking is consistent with comparable companies, and as each component of compensation for each executive officer is determined in relation to the 50th percentile of officers holding positions having similar responsibilities at comparable companies, the Compensation Committee believes that relative compensation among our executive officers is appropriate and consistent with maintaining internal pay equity.

Relationship Between Compensation Elements

Each element of executive officer compensation was determined with reference to the 50th percentile of the same element paid to executive officers holding the similar position at comparable companies. Therefore, no objective formula was utilized when determining the relative proportion of salary, cash incentive or equity awards relative to each other or to total compensation.

Employment Agreements and Termination Benefits

The employment agreement for each executive officer contains provisions related to termination and change of control. When establishing the termination and change of control provisions of the employment agreements, the Compensation Committee and the Board of Directors considered the Radford report, which provided recommendations to the Compensation Committee regarding the termination and change of control provisions for each executive officer based on publicly available information regarding the practices of our peer group, policy statements made by significant investor groups and an analysis of current market trends. We provide change in control protections to our officers to alleviate concerns regarding the possible occurrence of such a transaction, allowing them to focus their attention on our business. In addition, these protections encourage executives to remain with the Company during the threat or negotiation of a change in control transaction, which preserves our value and the potential benefit to be received by our stockholders in the transaction. The specific terms of the termination and change of control arrangements, as well as an estimate of the compensation that would have been payable had they been triggered as of the end of 2012, are described in detail in the section below entitled “Executive Compensation – Potential Payments Upon Termination/Change of Control.”

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee during fiscal year 2012 served as one of our officers, former officers or employees nor received directly or indirectly compensation from the Company, other than in the capacity as a member of our Board and Compensation Committee. There was no direct or indirect control by the members of the Compensation Committee of the Company. No member of the Compensation Committee, directly or indirectly, is the beneficial owner of more than 10% of the Company’s equity, nor are they an executive officer, employee, director, general partner or a managing member of one or more entities that are together the beneficial owners of more than 10% of the Company’s equity. The Compensation Committee members are not aware of any business or personal relationship between (i) a member of the Compensation Committee and any person who has provided or is providing advice to the Compensation Committee; and (ii) an executive officer of the company and any firm or other person who is employed or is employing such person to provide advice to the Compensation Committee. During fiscal year 2012, none of our executive officers served as a member of the compensation committee of any other entity, one of whose executive officers served as a member of our Board of Directors or Compensation Committee, and none of our executive officers served as a member of the board of directors of any other entity, one of whose executive officers served as a member of our Compensation Committee.

Compensation Committee Report

The Compensation Committee of the Board of Directors has reviewed and discussed “Compensation Discussion and Analysis” required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Board of Directors that the “Compensation Discussion and Analysis” be included in the our 2012 Annual Report on Form 10-K and this Proxy Statement.
