As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, including some of the compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an “emerging growth company” until the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more; (ii) December 31, 2018; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv)  the date on which we are deemed to be a large accelerated filer under SEC rules.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why is the Company Soliciting My Proxy?

Our board of directors is soliciting your proxy to vote at the 2014 annual meeting of stockholders to be held at Apella^™, 450 East 29th Street, 2nd Floor, New York, NY 10016, on Monday, June 30, 2014, at 2:00 p.m. local time and any adjournments or postponements of the meeting, which we refer to as the annual meeting. The proxy statement, along with the accompanying Notice of Annual Meeting of Stockholders, summarizes the purposes of the meeting and the information you need to know to vote at the annual meeting.

We have made available to you on the Internet or have sent you this proxy statement, the Notice of Annual Meeting of Stockholders, the proxy card and a copy of our Annual Report on Form 10-K for the fiscal year ended 2013 because you owned shares of our common stock on the record date. We intend to commence distribution of the proxy materials to stockholders on or about May 23, 2014.

Who Can Vote?

Only stockholders who owned our common stock at the close of business on May 14, 2014 are entitled to vote at the annual meeting. On this record date, there were 29,227,745 shares of our common stock outstanding and entitled to vote. Our common stock is our only class of voting stock.

You do not need to attend the annual meeting to vote your shares. Shares represented by valid proxies, received in time for the annual meeting and not revoked prior to the annual meeting, will be voted at the annual meeting. For instructions on how to change or revoke your proxy, see “May I Change or Revoke My Proxy?” below.

How Many Votes Do I Have?

Each share of our common stock that you own entitles you to one vote.

How Do I Vote?

Whether you plan to attend the annual meeting or not, we urge you to vote by proxy. All shares represented by valid proxies that we receive through this solicitation, and that are not revoked, will be voted in accordance with your instructions on the proxy card or as instructed via Internet or telephone. You may specify whether your shares should be voted for or withheld for each nominee for director and whether your shares should be voted for, against or abstain with respect to the other proposal. If you properly submit a proxy without giving specific voting instructions, your shares will be voted in accordance with the board of directors’ recommendations as

noted below. Voting by proxy will not affect your right to attend the annual meeting. If your shares are registered directly in your name through our stock transfer agent, Computershare Trust Company, N.A., or you have stock certificates registered in your name, you may vote:

Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m. Eastern Time on June 29, 2014.

If your shares are held in “street name” (held in the name of a bank, broker or other holder of record), you will receive instructions from the holder of record. You must follow the instructions of the holder of record in order for your shares to be voted. Telephone and Internet voting also will be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you plan to vote your shares in person at the annual meeting, you should contact your broker or agent to obtain a legal proxy or broker’s proxy card and bring it to the annual meeting in order to vote.

How Does the Board of Directors Recommend That I Vote on the Proposals?

The board of directors recommends that you vote as follows:

If any other matter is presented at the annual meeting, your proxy provides that your shares will be voted by the proxy holder listed in the proxy in accordance with his or her best judgment. At the time this proxy statement was first made available, we knew of no matters that needed to be acted on at the annual meeting, other than those discussed in this proxy statement.

May I Change or Revoke My Proxy?

If you give us your proxy, you may change or revoke it at any time before the annual meeting. You may change or revoke your proxy in any one of the following ways:

Your most current vote, whether by telephone, Internet or proxy card is the one that will be counted.

Table of Contents

What if I Receive More Than One Proxy Card?

You may receive more than one proxy card if you hold shares of our common stock in more than one account, which may be in registered form or held in street name. Please vote in the manner described above under “How Do I Vote?” for each account to ensure that all of your shares are voted.

Will My Shares be Voted if I Do Not Vote?

If your shares are registered in your name or if you have stock certificates, they will not be counted if you do not vote as described above under “How Do I Vote?” If your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above, the bank, broker or other nominee that holds your shares has the authority to vote your unvoted shares only on the ratification of the appointment of our independent registered public accounting firm (Proposal 2 of this proxy statement) without receiving instructions from you. Therefore, we encourage you to provide voting instructions to your bank, broker or other nominee. This ensures your shares will be voted at the annual meeting and in the manner you desire. A “broker non-vote” will occur if your broker cannot vote your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter or because your broker chooses not to vote on a matter for which it does have discretionary voting authority.

Your bank, broker or other nominee does not have the ability to vote your uninstructed shares in the election of directors. Therefore, if you hold your shares in street name it is critical that you cast your vote if you want your vote to be counted for the election of directors (Proposal 1 of this proxy statement). In the past, if you held your shares in street name and you did not indicate how you wanted your shares to be voted in the election of directors, your bank, broker or other nominee was allowed to vote your shares on your behalf in the election of directors as it deemed appropriate. Thus, 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, no votes will be cast on this proposal on your behalf.

Table of Contents

Is Voting Confidential?

We will keep all the proxies, ballots and voting tabulations private. We only let our Inspector of Election, Computershare Trust Company, N.A., examine these documents. Management will not know how you voted on a specific proposal unless it is necessary to meet legal requirements. We will, however, forward to management any written comments you make, on the proxy card or otherwise provide.

Where Can I Find the Voting Results of the Annual Meeting?

The preliminary voting results will be announced at the annual meeting, and we will publish preliminary, or final results if available, in a Current Report on Form 8-K within four business days of the annual meeting. If final results are unavailable at the time we file the Form 8-K, then we will file an amended report on Form 8-K to disclose the final voting results within four business days after the final voting results are known.

What Are the Costs of Soliciting these Proxies?

We will pay all of the costs of soliciting these proxies. Our directors and employees may solicit proxies in person or by telephone, fax or email. We will pay these employees and directors no additional compensation for these services. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward these proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their expenses.

What Constitutes a Quorum for the Annual Meeting?

The presence, in person or by proxy, of the holders of a majority of the voting power of all outstanding shares of our common stock entitled to vote at the annual meeting is necessary to constitute a quorum at the annual meeting. Votes of stockholders of record who are present at the annual meeting in person or by proxy, abstentions, and broker non-votes are counted for purposes of determining whether a quorum exists.

Attending the Annual Meeting

The annual meeting will be held at 2:00 p.m. local time on Monday, June 30, 2014, at Apella™, 450 East 29th Street, 2nd Floor, New York, NY 10016. When you arrive at the meeting site, signs will direct you to the appropriate meeting rooms. You need not attend the annual meeting in order to vote.

Householding of Annual Disclosure Documents

SEC rules concerning the delivery of annual disclosure documents allow us or your broker to send a single set of our proxy materials to any household at which two or more of our stockholders reside, if we or your broker believe that the stockholders are members of the same family. This practice, referred to as “householding,” benefits both you and us. It reduces the volume of duplicate information received at your household and helps to reduce our expenses. The rule applies to annual reports, proxy statements and information statements. Once you receive notice from your broker or from us that communications to your address will be “householded,” the practice will continue until you are otherwise notified or until you revoke your consent to the practice. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If your household received a single set of proxy materials this year, but you would prefer to receive your own copy, please contact our transfer agent, Computershare Trust Company, N.A., by calling their toll free number, 1-877-373-6374.

If you do not wish to participate in “householding” and would like to receive your own set of our proxy materials in future years, follow the instructions described below. Conversely, if you share an address with another stockholder and together both of you would like to receive only a single set of proxy materials, follow these instructions:

Description of the Merger and Private Placement in August 2013

On August 29, 2013, Intra-Cellular Therapies, Inc., or ITI, completed a reverse merger, referred to throughout this proxy statement as “the Merger,” with a public shell company named Oneida Resources Corp., or Oneida. Oneida was formed in August 2012 as a vehicle to investigate and, if such investigation warranted, acquire a target company or business seeking the perceived advantages of being a publicly held corporation. In the Merger, each outstanding share of capital stock of ITI was exchanged for 0.5 shares of common stock of Oneida, and each outstanding option and outstanding warrant of ITI was assumed by Oneida and became exercisable for 0.5 shares of Oneida common stock. As a result of the Merger and related transactions, ITI survived as a wholly-owned subsidiary of Oneida, Oneida changed its fiscal year end from March 31 to December 31, and Oneida changed its name to Intra-Cellular Therapies, Inc. In addition, we began operating ITI and its business, and therefore ceased being a shell company. Following the Merger and the redemption of all then outstanding shares of Oneida at the closing of the Merger, the former shareholders of ITI owned 100% of the shares of our outstanding capital stock.

Immediately prior to the Merger, on August 29, 2013, ITI sold to accredited investors approximately $60.0 million of its shares of common stock, or 18,889,307 shares at a price of $3.1764 per share, which we refer to throughout this proxy statement as the “Private Placement,” which included $15.3 million in principal and $0.8 million in accrued interest from the conversion of ITI’s then outstanding convertible promissory notes.

Except as indicated in footnotes to this table, we believe that the stockholders named in this table have sole voting and investment power with respect to all shares of common stock shown to be beneficially owned by them based on information provided to us by these stockholders, subject to community property laws, where applicable.

The principal occupation and employment during the past five years of each of our directors and nominees was carried on, in each case except as specifically identified above, with a corporation or organization that is not a parent, subsidiary or other affiliate of us. There is no arrangement or understanding between any of our directors or nominees and any other person or persons pursuant to which he or she is to be selected as a director or nominee.

There are no legal proceedings to which any of our directors is a party adverse to us or any of our subsidiaries or in which any such person has a material interest adverse to us or any of our subsidiaries.

Director Independence

Our board of directors has reviewed the materiality of any relationship that each of our directors has with Intercept, either directly or indirectly. Based upon this review, our board has determined that all of our directors other than Dr. Mates, our chief executive officer, are “independent directors” as defined by The NASDAQ Stock Market. In making such determinations, the board of directors considered the relationships that each such non-employee director or director nominee has with our company and all other facts and circumstances the board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In addition, our board of directors considered the association of certain of our directors with the holders of more than 5% of our common stock as well as the effect of each of the transactions described in “Certain Relationships and Related Person Transactions” below.

Committees of the Board of Directors and Meetings

Meeting Attendance. During the fiscal year ended December 31, 2013, there were ten meetings of our board of directors and one meeting of the compensation committee, which was the only standing committee of the board of directors. No director attended fewer than 75% of the total number of meetings of the board of directors and of committees of the board on which he or she served during fiscal 2013, other than Richard Lerner, M.D., who attended five of the ten board meetings held during his tenure, and Sir Michael Rawlins, M.D., FRCP, FMedSci, who attended five of the eight board meetings held during his tenure. Both Rory B. Riggs and Robert L. Van Nostrand were not elected to our board of directors until 2014. The board of directors has adopted a policy under which each member of our board of directors is strongly encouraged but not required to attend each annual meeting of our stockholders. We did not hold an annual meeting of stockholders in 2013.

Our board of directors has established an audit committee, a compensation committee and a nominating and governance committee. Each committee operates under a charter approved by our board of directors. Copies of each committee’s charter are posted on the Investor Relations section of our website, which is located at www.intracellulartherapies.com, under the caption “Corporate Governance.” The composition and function of each of these committees are described below.

Audit Committee. This committee currently has three members, Mr. Van Nostrand (Chairman), Sir Michael and Mr. Riggs. Our audit committee’s role and responsibilities are set forth in the audit committee’s written charter and include the authority to retain and terminate the services of our independent registered public accounting firm. In addition, the audit committee reviews the annual financial statements, considers matters relating to accounting policy and internal controls and reviews the scope of annual audits. All members of the

13

Table of Contents

audit committee satisfy the current independence standards promulgated by the Securities and Exchange Commission and by The NASDAQ Stock Market, as such standards apply specifically to members of audit committees. The board of directors has determined that Mr. Riggs is an “audit committee financial expert,” as the Securities and Exchange Commission has defined that term in Item 407 of Regulation S-K. Please also see the report of the audit committee set forth elsewhere in this proxy statement.

Compensation Committee. Our compensation committee met one time during fiscal 2013. This committee currently has three members, Mr. Marcus (Chairman), Dr. Alafi and Mr. Riggs. Our compensation committee’s role and responsibilities are set forth in the compensation committee’s written charter and includes reviewing, approving and making recommendations regarding our compensation policies, practices and procedures to ensure that legal and fiduciary responsibilities of the board of directors are carried out and that such policies, practices and procedures contribute to our success. Our compensation committee also administers our 2013 Equity Incentive Plan. The compensation committee is responsible for the determination of the compensation of our chief executive officer, and shall conduct its decision making process with respect to that issue without the chief executive officer present. All members of the compensation committee qualify as independent under the definition promulgated by The NASDAQ Stock Market.

Our compensation committee makes all compensation decisions regarding our executive officers and directors, after which it makes a recommendation to our full board of directors. Our board of directors then approves the compensation for our executive officers and directors.

During the last month of each fiscal year or the first calendar quarter of the following year, we evaluate each executive’s performance for that year. In connection with each annual review cycle, Dr. Mates, our president and chief executive officer, meets with our executive officers to discuss our accomplishments during the year and the individual’s performance and contributions over the prior year. Based on these discussions, Dr. Mates evaluates each executive’s performance. Dr. Mates also prepares her own self-assessment as well as a detailed review of company performance against stated corporate goals. This process leads to a recommendation by Dr. Mates to the compensation committee with respect to each executive officer, including herself, as to:

These recommendations are reviewed and taken into account by the compensation committee. The compensation committee makes a recommendation regarding executive compensation to the full board of directors, which then approves the compensation of our executive officers.

On March 6, 2014, our compensation committee engaged Pearl Meyer & Partners (“PM&P”), an independent compensation consultant, to assist the committee in determining a peer group of companies to use for director compensation based on our company’s current stage of development, to provide comparative data on director compensation practices in our industry and to generally advise us on our director compensation program. The compensation committee has the sole authority to approve the terms of the engagement of PM&P.

Although our board of directors and compensation committee consider the advice and recommendations of our independent compensation consultants as to our director compensation program, our board of directors and compensation committee ultimately make their own decisions about these matters. Our compensation committee may engage other independent compensation consultants to provide additional guidance for executive and director compensation and conduct further competitive benchmarking against a peer group of publicly traded companies.

Table of Contents

PM&P did not provide any services to us or our compensation committee other than as described above in connection with our executive and director compensation for 2013, although we may engage PM&P or another consultant in 2014 to provide services for us in connection with executive and director compensation for 2014. The compensation committee has assessed the independence of PM&P pursuant to SEC rules and concluded that PM&P’s work for the compensation committee does not raise any conflict of interest.

Our compensation committee will also review and discuss annually with management our “Compensation Discussion and Analysis” disclosure to the extent such disclosure is required by SEC rules. These rules are not yet applicable to us because we are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012. See the “Explanatory Note” at the beginning of this proxy statement.

Nominating and Governance Committee. Our nominating and governance committee has three members, Dr. Alafi (Chairman), Mr. Lerner and Mr. Marcus. The nominating and governance committee’s role and responsibilities are set forth in the nominating and governance committee’s written charter and include evaluating and making recommendations to the full board of directors as to the size and composition of the board of directors and its committees, evaluating and making recommendations as to potential candidates, and evaluating current board members’ performance. All members of the nominating and governance committee qualify as independent under the definition promulgated by The NASDAQ Stock Market.

If a stockholder wishes to nominate a candidate for director who is not to be included in our proxy statement, it must follow the procedures described in our By-Laws and in “Stockholder Proposals and Nominations for Director” at the end of this proxy statement.

In addition, under our current corporate governance policies, the nominating and governance committee may consider candidates recommended by stockholders as well as from other sources such as other directors or officers, third party search firms or other appropriate sources. For all potential candidates, the nominating and governance committee may consider all factors it deems relevant, such as a candidate’s personal integrity and sound judgment, business and professional skills and experience, independence, knowledge of the industry in which we operate, possible conflicts of interest, diversity, the extent to which the candidate would fill a present need on the board of directors, and concern for the long-term interests of the stockholders. In general, persons recommended by stockholders will be considered on the same basis as candidates from other sources. If a stockholder wishes to propose a candidate for consideration as a nominee by the nominating and governance committee under our corporate governance policies, it should submit recommendations for consideration in writing, addressed to the nominating and governance committee, care of our Corporate Secretary, at our principal offices. Submissions must be made by mail, courier or personal delivery; e-mailed submissions will not be considered. A nominating recommendation must be accompanied by the following information concerning each recommending shareholder:

15

Table of Contents

A nominating recommendation must be accompanied by the following information concerning the proposed nominee:

The recommending shareholder must also furnish a statement supporting its view that the proposed nominee possesses the minimum qualifications prescribed by the committee for nominees, and briefly describing the contributions that the nominee would be expected to make to the board and to the governance of the Company. The recommending shareholder must state whether, in the view of the shareholder, the nominee, if elected, would represent all shareholders and not serve for the purpose of advancing or favoring any particular shareholder or other constituency of the Company.

The nominating recommendation must be accompanied by the written consent of the proposed nominee to: (a) be considered by the committee and interviewed if the committee chooses to do so in its discretion, and (b) if nominated and elected, to serve as a director of the Company. The recommending shareholder must furnish the proposed nominee’s contact information for this purpose.

A shareholder (or group of shareholders) wishing to submit a nominating recommendation for an annual meeting of shareholders must ensure that it is received by the Company, as provided above, not later than 120 calendar days prior to the first anniversary of the date of the proxy statement for the prior annual meeting of shareholders. In the event that the date of the annual meeting of shareholders for the current year is more than 30 days following the first anniversary date of the annual meeting of shareholders for the prior year, the submission of a recommendation will be considered timely if it is submitted a reasonable time in advance of the mailing of our proxy statement for the annual meeting of shareholders for the current year.

If a recommendation is submitted by a group of two or more shareholders, the information regarding recommending shareholders set forth in paragraph three above must be submitted with respect to each shareholder in the group.

The nominating and governance committee considers issues of diversity among its members in identifying and considering nominees for director, and will strive where appropriate to achieve a diverse balance of backgrounds, perspectives, experience, age, gender, ethnicity and country of citizenship on the board of directors and its committees.

Board Leadership Structure and Role in Risk Oversight

Our board of directors does not have a policy regarding the separation of the roles of Chief Executive Officer and Chairman of the board of directors, as our board of directors believes it is in the best interest of the

16

Table of Contents

Company to make that determination based on the position and direction of the Company and the membership of the board of directors. Our board of directors has determined that having an employee director serve as Chairman is in the best interest of our stockholders at this time because of the efficiencies achieved in having the role of Chief Executive Officer and Chairman combined, and because the detailed knowledge of our day-to-day operations and business that the Chief Executive Officer possesses greatly enhances the decision-making processes of our board of directors as a whole. We have a strong governance structure in place, including independent directors, to ensure the powers and duties of the dual role are handled responsibly. We do not have a lead independent director.

The Chairman of the board of directors and the other members of the board of directors work in concert to provide oversight of our management and affairs. Our board of directors encourages communication among its members and between management and the board of directors to facilitate productive working relationships. Working with the other members of the board of directors, Dr. Mates also strives to ensure that there is an appropriate balance and focus among key board responsibilities such as strategic development, review of operations and risk oversight.

Stockholder Communications to the Board

Generally, stockholders who have questions or concerns should contact our Investor Relations department at 212-923-3344. However, any stockholders who wish to address questions regarding our business directly with the board of directors, or any individual director, should direct his or her questions in writing to the Chairman of the board of directors at Intra-Cellular Therapies, Inc., Attention: Chairman of the Board, 3960 Broadway, New York, New York 10032. Communications will be distributed to the board, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of the board of directors may be excluded, such as: junk mail and mass mailings, resumes and other forms of job inquiries, surveys and solicitations or advertisements.

In addition, any material that is unduly hostile, threatening, or illegal in nature may be excluded, provided that any communication that is filtered out will be made available to any outside director upon request.

Risks Related to Compensation Practices and Policies

Consistent with SEC disclosure requirements, we have assessed our compensation policies, practices and awards and have concluded that our compensation policies, practices and awards do not create risks that are reasonably likely to have a material adverse effect on the Company. Our management assessed our compensation and benefits programs to determine if the programs’ provisions and operations create undesired or unintentional risk of a material nature. We do not have any programs where the ability of a participant may directly affect variability or timing of payout. Rather, our compensation programs include a combination of fixed base salaries, cash bonuses, long-term incentive awards, and employee retirement plans that are generally uniform in design and operation throughout the company and with all levels of employees. The compensation policies and practices are substantially the same.

Based on the foregoing, we believe that our compensation policies, practices and awards do not create risks that are likely to have a material adverse effect on the company as a whole. We also believe that our incentive compensation arrangements provide incentives that do not encourage risk-taking beyond the organization’s ability to effectively identify and manage significant risks, are compatible with our effective internal controls and our risk management practices, and are supported by the oversight and administration of the compensation committee with regard to executive compensation programs.

Such severance benefits following a change of control are payable on condition that she executes a general release in favor of us, returns all our property and complies with her post-termination obligations under her employment agreement, her proprietary information, inventions, and non-competition agreement, and her general release.

Allen A. Fienberg, Ph.D. We entered into an employment agreement with Dr. Fienberg in February 2008, who has been our Vice President of Business Development since 2002. The agreement provides for a salary of $221,400 effective in February 2008, subject to our annual review and adjustment in the discretion of our board of directors, and that Dr. Fienberg is eligible for bonus payments and stock options as may be awarded by our board of directors.

In December 2013, he was awarded a bonus of $25,800, or 10% of his then base salary, for his performance during the fiscal year ended December 31, 2013. In addition, his employment agreement provides that we will pay the premium on a life insurance policy in an amount equal to one and one half times his base salary; however, we paid a premium in the amount of $276 on a life insurance policy with a face value of $150,000, to which he assented. For 2012, we also paid $7,650 in matching contributions under our 401(k) plan. The employment agreement also provides that Dr. Fienberg is entitled to participate in our benefit plans on the same basis as other executive level employees as well as long-term disability insurance and reimbursement for reasonable business expenses. The initial term of the agreement was three years and will be renewed for successive one year terms, unless we or Dr. Fienberg provides notice that we or he, as the case may be, does not wish to renew the agreement or wishes to renew the agreement on different terms than those contained in the agreement.

If Dr. Fienberg’s employment is terminated for any reason, he will be entitled to compensation and benefits through the last day of his employment, including accrued but untaken vacation. If his employment is terminated due to his death or disability, we will also pay him or his estate the compensation which would otherwise have been payable to him through the end of the month in which such termination occurs as well as payment for any accrued but untaken vacation. If his employment is terminated without cause by us or he terminates his employment for good reason, he will receive the following severance benefits following his employment termination, on condition that he executes a general release in our favor: (a) payment of 12 months of his then current base salary and the pro rata portion of an amount equal to the bonus he was awarded for the previous year, if any, which severance payments will be paid in one lump sum on the date the general release he executes becomes effective; (b) payment for 12 months of the portion of the COBRA premiums that we paid prior to his termination; and (c) all of his unvested stock options will become fully vested and exercisable. Dr. Fienberg will also be entitled to such severance benefits if we elect not to renew his employment agreement for reasons other than death, disability or cause, but (i) such severance benefits are conditioned on Dr. Fienberg executing a general release in our favor, returning all our property, and complying with his employment agreement, proprietary information, inventions, and non-competition agreement, and the general release and (ii) Dr. Fienberg will not be eligible for such severance benefits if he or we wish to renew the agreement on different terms than those contained in his employment agreement. In the event of a change of control, 75% of his unvested stock options and restricted stock will immediately vest.

Pursuant to his proprietary information, inventions, and non-competition agreement, Dr. Fienberg has agreed to not (i) solicit customers, consultants, contractors or employees of ours for a period of one year after the termination of his employment or (ii) compete with us for a period of one year after the later of the termination of his employment or the date a court of competent jurisdiction enters an order enforcing the non-competition provision.

The meanings of the terms “cause,” “good reason,” “disability” and “change of control” for purposes of these employment agreements are described below under “Potential Payments upon Termination or Change in Control.”

Director Compensation

The following table shows the total compensation paid or accrued during the fiscal year ended December 31, 2013 to each of our directors, other than Dr. Mates who does not receive compensation for her service as a director.

Director Compensation Policy

As compensation to our non-employee directors for the year ended December 31, 2013 and 2012, we granted options to purchase 20,000 shares, and 12,500 shares of our common stock, respectively, to each of our non-employee directors serving during such years. We granted any non-employee director who resigned from or joined the ITI board of directors during such years the pro rata portion of the annual option grant representing the portion of such year during which such non-employee director served. We intend to adopt a non-employee director compensation policy designed to ensure that the compensation aligns the directors’ interests with the long-term interests of the stockholders, that the structure of the compensation is simple, transparent and easy for stockholders to understand and that our directors are fairly compensated.

EQUITY COMPENSATION PLAN INFORMATION

The following table provides certain aggregate information with respect to all of our equity compensation plans in effect as of December 31, 2013.

2003 Equity Incentive Plan

The ITI 2003 Equity Incentive Plan, as amended, was adopted by the board of directors of ITI in July 2003 and by the stockholders of ITI in September 2003. The 2003 Equity Incentive Plan was subsequently amended in January 2006, February 2010 and December 2012, and expired by its terms in July 2013. As a result of such expiration, no additional awards may be granted under the 2003 Equity Incentive Plan, but equity awards previously granted under the 2003 Equity Incentive Plan will remain outstanding and continue to be governed by the terms of the 2003 Equity Incentive Plan. In connection with the Merger, we assumed the options then outstanding under the 2003 Equity Incentive Plan, and immediately following the Merger on August 29, 2013, the only outstanding awards under the 2003 Equity Incentive Plan were options to purchase 1,462,380 shares of our common stock. The 2003 Equity Incentive Plan is administered by our board of directors.

If we are acquired, the surviving or acquiring company may assume or continue the outstanding options by substituting either (a) the consideration payable with respect to the outstanding shares of common stock in connection with the acquisition or (b) shares of stock of the successor or acquiring company. If the surviving or acquiring company does not assume or continue the outstanding options, the outstanding options will be accelerated in full prior to the effective time of the acquisition and will terminate if not exercised at or prior to such effective time.

2013 Equity Incentive Plan

In August 2013, our board of directors approved the 2013 Equity Incentive Plan. The 2013 Equity Incentive Plan became effective on November 7, 2013. Unless sooner terminated by our board of directors or our stockholders, the 2013 Equity Incentive Plan will expire 10 years from its date of effectiveness. Under our 2013

30

Table of Contents

Equity Incentive Plan, we may grant incentive stock options, nonstatutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and other stock awards to our employees, directors and consultants.

As of December 31, 2013, the maximum number of shares of our common stock that may be delivered in satisfaction of awards under the 2013 Equity Incentive Plan is 837,390 shares, plus up to an additional maximum of 1,400,125 shares which may be issued solely after the cancellation or expiration of any unexercised stock options that we assumed in the Merger. These numbers are subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

In addition, the 2013 Equity Incentive Plan contains an “evergreen” provision, which allows for an annual increase in the number of shares of our common stock available for issuance under the 2013 Equity Incentive Plan on January 1 of each year commencing on January 1, 2014 and ending upon expiration of the 2013 Equity Incentive Plan. Effective January 1, 2014, our board of directors approved for reservation an additional 800,000 shares of our common stock for issuance under the 2013 Equity Incentive Plan pursuant to the “evergreen” provision of the 2013 Equity Incentive Plan. In the future, the annual increase in the number of shares shall be equal to the lesser of:

Shares of our common stock to be issued under the 2013 Equity Incentive Plan may be authorized but unissued shares of our common stock or previously issued shares acquired by us. Any shares of our common stock underlying awards that otherwise expire, terminate, or are forfeited or reacquired by us will again be available for issuance under the 2013 Equity Incentive Plan.

The 2013 Equity Incentive Plan is administered by our compensation committee. Our compensation committee has full power and authority to determine the terms of awards granted pursuant to this plan, including:

However, at such time as we may be subject to Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code, a maximum of 200,000 shares of our common stock subject to options, stock appreciation rights and other awards whose value is determined by reference to an increase over an exercise or strike price of at least 100% of the fair market value on the date the award is granted may be granted to any one participant during any one calendar year.

Our board of directors may amend or discontinue the 2013 Equity Incentive Plan at any time and may amend any outstanding award. No such amendment may materially impair the rights under any outstanding award without the holder’s consent. Stockholder approval will be required for any amendment to the 2013 Equity Incentive Plan to the extent such approval is required by law, including the Code or applicable stock exchange requirements.

31

Table of Contents

If we are acquired, our board of directors will (i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the award or to substitute a similar award for the award; (ii) cancel or arrange for the cancellation of the award, to the extent not vested or not exercised prior to the effective time of the transaction, in exchange for such cash consideration, if any, as our board of directors in its sole discretion, may consider appropriate; and (iii) make a payment, in such form as may be determined by our board of directors equal to the excess, if any, of (A) the value of the property the holder would have received upon the exercise of the award immediately prior to the effective time of the transaction, over (B) any exercise price payable by such holder in connection with such exercise. In addition in connection with such transaction, our board of directors may accelerate the vesting, in whole or in part, of the award (and, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such transaction and may arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by the Company with respect to an award.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers, and persons who own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than ten percent stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations regarding the filing of required reports, we believe that all Section 16(a) filing requirements applicable to our directors, executive officers and greater-than-ten-percent beneficial owners with respect to fiscal 2013 were met.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

In addition to the director and executive officer compensation arrangements discussed above in “Executive Officer and Director Compensation,” since January 1, 2012, we have engaged in the following transactions in which the amount involved exceeded the lesser of $120,000 or one percent of the average of our total assets at year end for the last two completed fiscal years and in which any director, executive officer or holder of more than 5% of our voting securities, whom we refer to as our principal stockholders, or affiliates or immediate family members of our directors, executive officers and principal stockholders, had or will have a material interest. We believe that all of these transactions were on terms as favorable as could have been obtained from unrelated third parties.

As described above, the following executive officers and directors held the following positions at ITI prior to the Merger:

Some of our directors are affiliated with our principal stockholders as indicated in the table below:

Table of Contents

The directors of ITI were previously selected as directors of ITI in accordance with the terms of ITI’s then existing restated certificate of incorporation, which was no longer effective following the Merger, and ITI’s Second Amended and Restated Voting Agreement effective as of October 25, 2007, as amended, which was terminated immediately prior to the Effective Time of the Merger.

Convertible Promissory Notes Issued in 2012 and 2013

In October 2012, ITI entered into a convertible note purchase agreement with certain investors pursuant to which ITI issued convertible promissory notes having an aggregate principal amount of approximately $15.3 million, which were issued on October 25, 2012, November 14, 2012 and March 20, 2013. Certain of these convertible promissory notes were purchased by our principal stockholders and affiliates of our directors in the following amounts and on the following dates:

The convertible promissory notes were unsecured, accrued interest at the rate of 6% per year and had a maturity date of October 25, 2013. The convertible promissory notes converted into shares of ITI common stock in connection with the Private Placement discussed in “—Common Stock Issued in Private Placement in 2013” below. In addition, ITI paid $7,200 to the purchasers’ legal counsel for fees and expenses of purchasers’ legal counsel incurred in connection with the convertible promissory note financing.

Common Stock Issued in Private Placement in 2013

The following table summarizes ITI’s sales of its common stock on August 29, 2013 in the Private Placement to our officers, directors and beneficial owners of more than five percent of any class of our voting securities. The purchase price of $3.1764 per share (as adjusted to $6.3528 after giving effect to the Merger) was the fair market value as determined by arms-length negotiations between sophisticated investors and ITI’s management and board of directors. In addition, the holders of the convertible promissory notes issued to certain principal stockholders and an affiliate of one of our directors in 2012 elected to convert the aggregate principal amount plus accrued interest on all of ITI’s outstanding convertible promissory notes into shares of ITI common stock at the purchase price of $3.1764 per share (as adjusted to $6.3528 after giving effect to the Merger). ITI received no additional consideration from the conversion of the convertible promissory notes.

At the Effective Time of the Merger, on August 29, 2013, each share of ITI preferred stock and ITI common stock outstanding immediately prior to the Effective Time was exchanged for 0.5 shares of our common stock.

Assumption of Outstanding Stock Options in Merger

At the Effective Time, on August 29, 2013, we assumed all options to purchase ITI common stock then outstanding under the ITI 2003 Equity Incentive Plan, and such options became exercisable for an aggregate of 1,462,380 shares of Company common stock, subject to the vesting and other terms of such options. The vesting of such options was not accelerated as a result of the Merger. The following table provides the number of outstanding options and the weighted average exercise price of such options under the 2003 Equity Incentive Plan held by our officers, directors and beneficial owners of more than five percent of any class of our voting securities that we assumed from ITI in connection with the Merger, as adjusted for the exchange ratio in the Merger:

The Redemption

Immediately following the Effective Time, pursuant to the terms of a Redemption Agreement dated August 29, 2013 by and among the Company and its then-current sole stockholder, we completed the closing of a redemption of 5,000,000 shares of Company common stock from our then-current sole stockholder in consideration of $60,000, plus professional costs related to the transaction that were approximately $20,000. The 5,000,000 shares constituted all of the issued and outstanding shares of the Company’s capital stock, on a fully-diluted basis, immediately prior to the Merger.

Participation in Our Public Offering

New Ventures I, LLC, of which Mr. Riggs, one of our directors, purchased 28,571 shares of common stock in our public offering which closed on February 5, 2014 at the public offering price of $17.50 per share. In addition, we believe entities affiliated with Fidelity Investments also purchased an aggregate of 1,550,000 shares of common stock in the offering at the public offering price.

Agreements with Stockholders

Termination of Existing Stockholder Agreements

In connection with ITI’s Series C preferred stock financing in 2007 and 2010, ITI entered into various stockholder agreements with the holders of its common stock and preferred stock relating to voting rights, information rights and registration rights, among other things. The stockholder agreements terminated immediately prior to the Effective Time of the Merger. Parties to the existing registration rights agreement, however, as well as our directors and executive officers and all of our other stockholders, were provided with an opportunity to become parties to the registration rights agreement that ITI entered into in connection with the Private Placement, as discussed below under “—Registration Rights Agreement.”

Registration Rights Agreement

At the closing of the Private Placement, ITI entered into a registration rights agreement with the investors in the Private Placement and also the existing stockholders of ITI who agreed to become parties to certain provisions of the agreement or who choose to become parties in the future, which covers substantially all of our outstanding shares of common stock as of December 31, 2013. We assumed the registration rights agreement in connection with the Merger. Pursuant to the registration rights agreement and subject to the rules and regulations of the SEC, we have agreed to file a shelf registration statement covering the resale of the shares of our common stock held by the investors in the Private Placement and the shares of our common stock held by the former stockholders of ITI who are parties to the agreement. We were required to file the shelf registration statement within 45 days of the date of the registration rights agreement (October 13, 2013), which we filed on September 18, 2013 and which was declared effective on December 18, 2013.

We will be liable to each investor in the Private Placement (but not to the former stockholders of ITI who are parties to the agreement) for liquidated damages, on a 30-day basis, equal to 1.0% of the aggregate purchase price paid by the investor for the registrable shares of our common stock then held by the investor, subject to an overall cap of 5%, (i) if we suspend (subject to limited blackout periods described below) or terminate the registration statement prior to the earlier of December 18, 2016 and the date on which all of the registrable shares cease to be registrable shares, or (ii) in the event one or more suspensions of the effectiveness of the registration statement exceeds 60 days in the aggregate during any 12-month period. We will be permitted to suspend the registration statement one or more times during any 12-month period provided such suspensions do not exceed 30 consecutive days or 60 days in the aggregate in any 12-month period. Any suspension associated with our filing of an annual, periodic or current report, as required by the Exchange Act, will be permitted and will not be counted against the 60 day limitation. Expenses with respect to the filing and effectiveness of such registration statement (but not selling expenses, or underwriter or agent compensation) will be paid by us, including expenses of one counsel for the selling stockholders.

Lock-up Provisions in Registration Rights Agreement

One of the provisions of the registration rights agreement that was applicable to the former stockholders of ITI who are parties to the agreement (other than the investors in the Private Placement), who hold an aggregate of approximately 12,607,110 shares of common stock, is a lock-up provision pursuant to which these stockholders agreed, subject to specified exceptions, not to sell, transfer, dispose of, contract to sell, sell any option or contract to purchase, or otherwise transfer or dispose of, directly or indirectly, without the written consent of Leerink Partners LLC, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock prior to April 30, 2014. These lock-up provisions did not apply to, among other things, shares of common stock acquired in connection with any follow-on securities offerings by us or in open market transactions, or upon the exercise of stock options granted pursuant to our equity incentive plans, so long as the shares acquired upon exercise remain subject to the lock-up provisions in the agreement, or certain gifts and other transfers for estate-planning purposes or by stockholders who are entities to their limited partners, members or stockholders, as specified in the agreement. In the event that a former stockholder of ITI was also an

39

Table of Contents

investor in the Private Placement, then these lock-up provisions in the agreement only applied with respect to the shares held by such stockholder that were not purchased in the Private Placement. These lock-up provisions expired on April 30, 2014 pursuant to their terms.

Lock-up Agreements

We and each of our directors and executive officers and certain stockholders, who collectively own 16,437,038 shares of our common stock, agreed in connection with our public offering of shares of common stock which closed on February 5, 2014, that, without the prior written consent of Leerink Partners LLC and Cowen and Company, LLC, on behalf of the underwriters, we and our directors and executive officers and certain stockholders would not, subject to limited exceptions, directly or indirectly sell or dispose of any shares of our common stock or any securities convertible into or exchangeable or exercisable for shares of our common stock prior to April 30, 2014, subject to extension as provided in the lock-up agreement. The lock-up agreement also contained certain exceptions for, among other things, certain transfers as gifts; transfers by stockholders who are entities to their limited or general partners, members, stockholders or affiliates, as specified in the agreement; transfers to immediate family members or other transfers for estate-planning purposes; dispositions of shares acquired in open market transactions after the completion of the public offering; dispositions of shares acquired in the Private Placement; and the establishment of trading plans pursuant to Rule 10b5-1 under the Exchange Act. These lock-up agreements expired on April 30, 2014 pursuant to their terms.

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and certain of our officers. The indemnification agreements, our restated certificate of incorporation and our restated bylaws require us to indemnify our directors and officers to the fullest extent permitted by Delaware law. In addition, as a condition to the Merger, we also entered into an indemnity agreement with the former sole officer and director of the Company pursuant to which we agreed to indemnify him for actions taken by him in his official capacities relating to the consideration, approval and consummation of the Merger and certain related transactions.

As a condition to the Merger, we entered into an Indemnity Agreement with our former sole officer and director pursuant to which we agreed to indemnify such former officer and director for actions taken by him in his official capacities relating to the consideration, approval and consummation of the Merger and certain related transactions.

Lease Agreement

On March 31, 2014, we entered into a long-term lease with ARE-East River Science Park LLC for approximately 12,000 square feet of useable laboratory and office space located at 430 East 29th Street, New York, New York 10016, which we expect to occupy as our headquarters on or about February 2015. The cost for rent and maintenance of common areas will initially be approximately $1.3 million per year, with base rent subject to annual increases of 3%. The lease has a term of five years. Joel S. Marcus, one of our directors, is co-founder, Chairman of the board of directors, Chief Executive Officer, President and a director of Alexandria Real Estate Equities, Inc., which is the parent company to the landlord under the lease.

Policy for Approval of Related Person Transactions

Pursuant to the written charter of our audit committee, the audit committee is responsible for reviewing and approving, prior to our entry into any such transaction, all transactions in which we are a participant and in which any parties related to us, including our executive officers, our directors, beneficial owners of more than 5% of our securities, immediate family members of the foregoing persons and any other persons whom our board of directors determines may be considered related parties under Item 404 of Regulation S-K, has or will have a direct or indirect material interest.

40

Table of Contents

In reviewing and approving such transactions, the audit committee will obtain, or will direct our management to obtain on its behalf, all information that the committee believes to be relevant and important to a review of the transaction prior to its approval. Following receipt of the necessary information, a discussion will be held of the relevant factors if deemed to be necessary by the committee prior to approval. If a discussion is not deemed to be necessary, approval may be given by written consent of the committee. This approval authority may also be delegated to the chair of the audit committee in some circumstances. No related party transaction will be entered into prior to the completion of these procedures.

The audit committee or its chair, as the case may be, will approve only those related party transactions that are determined to be in, or not inconsistent with, the best interests of us and our stockholders, taking into account all available facts and circumstances as the committee or the chair determines in good faith to be necessary in accordance with principles of Delaware law generally applicable to directors of a Delaware corporation. These facts and circumstances will typically include, but not be limited to, the benefits of the transaction to us; the impact on a director’s independence in the event the related party is a director, an immediate family member of a director or an entity in which a director is a partner, stockholder or executive officer; the availability of other sources for comparable products or services; the terms of the transaction; and the terms of comparable transactions that would be available to unrelated third parties or to employees generally. No member of the audit committee will participate in any review, consideration or approval of any related party transaction with respect to which the member or any of his or her immediate family members has an interest.

In the event that either nominee becomes unable or unwilling to serve, the shares represented by the enclosed proxy will be voted for the election of such other person as the board of directors may recommend in that nominee’s place. We have no reason to believe that any nominee will be unable or unwilling to serve as a director.

A plurality of the shares voted “For” each nominee at the annual meeting is required to elect each nominee as a director.

THE BOARD OF DIRECTORS RECOMMENDS THE ELECTION OF RICHARD LERNER, M.D. AND SIR MICHAEL RAWLINS, M.D., FRCP, FMEDSCI AS DIRECTORS, AND PROXIES SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR THEREOF UNLESS A STOCKHOLDER HAS INDICATED OTHERWISE ON THE PROXY.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee has appointed Ernst & Young LLP, as our independent registered public accounting firm, to audit our financial statements for the fiscal year ending December 31, 2014. The board of directors proposes that the stockholders ratify this appointment. Ernst & Young LLP audited our financial statements for the fiscal year ended December 31, 2013. We expect that representatives of Ernst & Young LLP will be present at the annual meeting, will be able to make a statement if they so desire, and will be available to respond to appropriate questions.

In deciding to appoint Ernst & Young LLP, the audit committee reviewed auditor independence issues and existing commercial relationships with Ernst & Young LLP and concluded that Ernst & Young LLP has no commercial relationship with the Company that would impair its independence for the fiscal year ending December 31, 2014.

The following table presents fees for professional audit services rendered by Ernst & Young LLP for the audit of our annual financial statements for the years ended December 31, 2013 and December 31, 2012, and fees billed for other services rendered by Ernst & Young LLP during that period.

Prior to our application for listing on the NASDAQ Global Select Market in January 2014, we did not have a separate audit committee, and our full board of directors served in that function.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-audit Services of Independent Public Accountant

Consistent with SEC policies regarding auditor independence, the audit committee has responsibility for appointing, setting compensation and overseeing the work of our independent registered public accounting firm. In recognition of this responsibility, the audit committee has established a policy to pre-approve all audit and permissible non-audit services provided by our independent registered public accounting firm.

Prior to engagement of an independent registered public accounting firm for the next year’s audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services to the audit committee for approval.

1. Audit services include audit work performed in the preparation of financial statements, as well as work that generally only an independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits, and attest services and consultation regarding financial accounting and/or reporting standards.

2. Audit-Related services are for assurance and related services that are traditionally performed by an independent registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.

3. Tax services include all services performed by an independent registered public accounting firm’s tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance, tax planning, and tax advice.

4. Other Fees are those associated with services not captured in the other categories. We generally do not request such services from our independent registered public accounting firm.

Prior to engagement, the audit committee pre-approves these services by category of service. The fees are budgeted and the audit committee requires our independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage our independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the audit committee requires specific pre-approval before engaging our independent registered public accounting firm.

The audit committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the audit committee at its next scheduled meeting.

In the event the stockholders do not ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm, the audit committee will reconsider its appointment.

The affirmative vote of a majority of the shares cast affirmatively or negatively at the annual meeting is required to ratify the appointment of the independent registered public accounting firm.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE TO RATIFY THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, AND PROXIES SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR OF SUCH RATIFICATION UNLESS A STOCKHOLDER INDICATES OTHERWISE ON THE PROXY.
