PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD JUNE 15, 2007

QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING

Why am I receiving these materials?

We have sent you this proxy statement and the enclosed proxy card because the Board of Directors of ACADIA Pharmaceuticals Inc. (sometimes referred to as the “Company”, “ACADIA”, “we”, “our” or “us”) is soliciting your proxy to vote at the 2007 Annual Meeting of Stockholders. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card.

The Company intends to mail this proxy statement and accompanying proxy card on or about May 15, 2007 to all stockholders of record entitled to vote at the annual meeting.

Who can vote at the annual meeting?

Only stockholders of record at the close of business on April 16, 2007 will be entitled to vote at the annual meeting. On this record date, there were 35,965,016 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on April 16, 2007 your shares were registered directly in your name with ACADIA’s transfer agent, Mellon Investor Services, then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on April 16, 2007 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.

What am I voting on?

There are two matters scheduled for a vote:

•

Election of two directors; and

•

Ratification of PricewaterhouseCoopers LLP as independent auditors of the Company for its fiscal year ending December 31, 2007.

How do I vote?

You may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the annual meeting or vote by proxy using the enclosed proxy card. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy.

•

To vote in person, come to the annual meeting and we will give you a ballot when you arrive.

•

To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than from ACADIA. Simply complete and mail the proxy card to ensure that your vote is counted. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 16, 2007.

What if I return a proxy card but do not make specific choices?

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted “For” the election of each of the two nominees for director, “For” the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one proxy card?

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:

•

You may submit another properly completed proxy card with a later date.

•

You may send a timely written notice that you are revoking your proxy to ACADIA’s Secretary at 3911 Sorrento Valley Boulevard, San Diego, California 92121.

•

You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

When are stockholder proposals due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by January 16, 2008, to Thomas H. Aasen, Secretary, ACADIA Pharmaceuticals Inc., 3911 Sorrento Valley Boulevard, San Diego, California 92121. If you wish to submit a proposal that is not to be included in next year’s proxy materials, your proposal generally must be submitted in writing to the same address no later than March 17, 2008 but no earlier than February 15, 2008. Please review our bylaws, which contain additional requirements regarding advance notice of stockholder proposals.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count “For” and “Withhold” and, with respect to proposals other than the election of directors, “Against” votes, abstentions and broker non-votes. Abstentions will be counted towards the vote total for each proposal, and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal

What are “broker non-votes”?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed “non-routine.” Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are generally those involving a contest or a matter that may substantially affect the rights or privileges of shareholders, such as mergers or shareholder proposals.

How many votes are needed to approve each proposal?

•

For the election of directors, the two nominees receiving the most “For” votes (from the holders of the shares present in person or represented by proxy and entitled to vote on the election of directors) will be elected. Only votes “For” or “Withheld” will affect the outcome.

•

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares are present at the meeting in person or represented by proxy. On the record date, there were 35,965,016 shares outstanding and entitled to vote. Thus, the holders of 17,982,509 shares must be present in person or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the meeting in person or represented by proxy may adjourn the meeting to another date.

How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting. Final voting results will be published in the Company’s quarterly report on Form 10-Q for the second quarter of 2007.

PROPOSAL 1

ELECTION OF DIRECTORS

ACADIA’s Board of Directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including a vacancy created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is elected and qualified.

The Board of Directors presently has eight members. There are two directors in Class III, whose term of office expires in 2007, and there is one vacancy resulting from the resignation of Mark R. Brann in October 2006. Stockholders may not vote for a greater number of nominees than two. The two nominees for Class III directors are Leslie Iversen and Gordon Binder. Each of the nominees is currently a director of ACADIA. Each of these nominees was elected by our stockholders prior to our initial public offering. If elected at the annual meeting, each of these nominees would serve until the 2010 annual meeting and until his or her successor is elected and has qualified, or, if sooner, until the director’s death, resignation or removal. The terms of the directors in Classes I and II expire at our 2008 and 2009 Annual Meetings of Stockholders, respectively. It is the Company’s policy to encourage directors and nominees for director to attend the Annual Meeting. Eight of the nine directors attended the 2006 Annual Meeting of Stockholders.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. The two nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the two nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by ACADIA’s management. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE IN FAVOR OF EACH NAMED NOMINEE.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of the Board of Directors

As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. Our Board of Directors consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the Nasdaq, as in effect time to time.

Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that all of our directors are independent directors within the meaning of the applicable Nasdaq listing standards, except for Dr. Hacksell, our Chief Executive Officer.

Our independent directors meet quarterly in regularly scheduled executive sessions at which only non-employee directors are present and which were presided over by the Chairman of the Board. All of the committees of our Board of Directors are comprised entirely of directors determined by the Board to be independent within the meaning of the applicable Nasdaq listing standards.

Meetings of the Board of Directors

The Board of Directors met six times during the last fiscal year, including two telephonic meetings. All directors except Mr. Binder attended at least 75% of the aggregate of the meetings of the Board and of the committees on which they served, held during the period for which they were directors or committee members, respectively.

Information Regarding Committees of the Board of Directors

The Board has an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides membership and meeting information for fiscal 2006:

(1)	Dr. Brann resigned from the Board of Directors, and as our President and Chief Scientific Officer, as of October 20, 2006.

Below is a description of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee of the Board of Directors. The Board of Directors has determined that each member of such committees meets the applicable Nasdaq rules and regulations regarding “independence” and that each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

Audit Committee

The Audit Committee of the Board of Directors is composed of three directors and was established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (the “Exchange Act”) to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. The Audit Committee operates pursuant to a written charter that is available on our website at http://www.acadia-pharm.com. The functions of the Audit Committee include, among other things:

•

reviewing and pre-approving the engagement of our independent registered public accounting firm to perform audit services and any permissible non-audit services,

•

reviewing our annual and quarterly results, financial statements and reports and discussing the statements and reports with our independent registered public accounting firm and management,

•

reviewing and discussing with our independent registered public accounting firm and management, as appropriate, significant issues that arise regarding accounting principles and financial statement presentation, and matters concerning the scope, adequacy and effectiveness of our financial controls,

•

establishing procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal auditing controls or auditing matters, and

•

establishing procedures for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters.

The Board of Directors reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Audit Committee are independent (as independence is currently defined in the applicable Nasdaq listing standards). Our Board of Directors has determined that Mr. Binder qualifies as an “audit committee financial expert,” as defined in applicable Securities and Exchange Commission (“SEC”) rules. The Board made a qualitative assessment of Mr. Binder’s level of knowledge and experience based on a number of factors, including his formal education, prior experience and business acumen.

Report of the Audit Committee of the Board of Directors

AU section 380), as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T. The Audit Committee has also received the written disclosures and the letter from the independent accountants required by the Independence Standards Board Standard No. 1, (Independence Discussions with Audit Committees), as adopted by the PCAOB in Rule 3600T and has discussed with the independent accountants the independent accountant’s independence. Based on the foregoing, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in our Annual Report in Form 10-K for the fiscal year ended December 31, 2006. The Audit Committee also has engaged PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2007 and is seeking ratification of such selection by the stockholders.

Compensation Committee

The Compensation Committee is composed of three directors and all members of the Compensation Committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards. The Compensation Committee operates pursuant to a written charter that is available on our website at http://www.acadia-pharm.com. The functions of the Compensation Committee include, among other things:

•

determining the compensation and other terms of employment of our executive officers and reviewing and suggesting corporate performance goals and objectives relevant to such compensation, which shall support and reinforce our long-term strategic goals,

•

recommending to our Board of Directors the type and amount of compensation to be paid or awarded to non-employee directors for their service on our Board of Directors and its committees,

•

evaluating and recommending to our Board of Directors the equity incentive plans, compensation plans and similar programs advisable for us, as well as modification or termination of existing plans and programs,

•

establishing policies with respect to equity compensation arrangements, and

•

reviewing the terms of any employment agreements, severance arrangements, change-in-control protections and any other compensatory arrangements for our executive officers and approving any such agreements for all officers prior to approval by the Board of Directors.

Commencing this year, the Compensation Committee also began to review with management the Company’s Compensation Discussion and Analysis and to consider whether to recommend that it be included in proxy statements and other filings.

Compensation Committee Processes and Procedures. Typically, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with management. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, provide financial or other background information or advice or otherwise participate in Compensation Committee meetings. The Chief Executive Officer does not participate in, and is not present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company, as well as authority to obtain, at the expense of the Company, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. In particular, the Compensation Committee has authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms.

Under its charter, the Compensation Committee may form, and delegate authority to, subcommittees, as appropriate. In 1998, the Compensation Committee formed a Non-Officer Stock Option Committee, currently composed of Dr. Hacksell, to which it delegated authority to grant, without any further action required by the Compensation Committee, stock options to employees who are not officers of the Company. The purpose of this delegation of authority is to enhance the flexibility of option administration within the Company and to facilitate the timely grant of options to non-management employees, particularly new employees, within specified limits approved by the Compensation Committee. Specific authority of the Non-Officer Stock Option Committee is specified on a quarterly basis, but, generally, this subcommittee may not grant options to acquire more than an aggregate of 150,000 shares per quarter or 25,000 shares per employee. Typically, as part of its oversight function, the Compensation Committee will review on a quarterly basis the list of grants made by the subcommittee.

Historically, the Compensation Committee has made adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings held during the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive

Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives, as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, executive stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels, compensation surveys, and recommendations of any compensation consultant, if applicable.

The specific determinations of the Compensation Committee with respect to executive compensation for fiscal 2006 are described in greater detail in the Compensation Discussion and Analysis section of this proxy statement.

Compensation Committee Interlocks and Insider Participation

As indicated above, the Compensation Committee consists of Drs. Kaplan and Walton and Mr. Rasmussen. No member of the Compensation Committee has ever been an officer or employee of ours. None of our executive officers currently serves, or has served during the last completed fiscal year, on the compensation committee or board of directors of any other entity that has one or more executive officers serving as a member of our Board of Directors or Compensation Committee.

Compensation Committee Report

The material in this report is not “soliciting material” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis contained in this proxy statement. Based on this review and discussion, the Compensation Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated into our Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

The foregoing report has been furnished by the Compensation Committee.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee operates pursuant to a written charter that is available on our website at http://www.acadia-pharm.com. The functions of the Nominating and Corporate Governance Committee include, among other things:

•

interviewing, evaluating, nominating and recommending individuals for membership on our Board of Directors,

•

evaluating nominations by stockholders of candidates for election to our Board of Directors,

•

evaluating director performance on our Board of Directors and applicable committees of the Board and determining whether continued service on the Board is appropriate,

•

developing, reviewing and amending a set of corporate governance policies and principles, including our Code of Business Conduct and Ethics,

•

considering questions of possible conflicts of interest of directors as such questions arise, and

•

overseeing and reviewing the processes and procedures we use to provide information to the Board of Directors and its committees.

Candidates for director nominees are reviewed in the context of the current composition of our Board of Directors, our operating requirements and the long-term interests of our stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee considers skills, diversity, age, and such other factors as it deems appropriate given the current needs of the Board of Directors and ACADIA, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews such directors’ overall service to us during their term, including the number of meetings attended, level of participation, quality of performance, and any other relevant considerations. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee would be independent under applicable Nasdaq listing standards and SEC rules and regulations with the advice of counsel, if necessary. The Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of our Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider candidates’ qualifications and selects candidates for recommendation to the Board by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, based on whether the candidate was recommended by a stockholder or not. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee must do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 3911 Sorrento Valley Boulevard, San Diego, California 92121. Each submission must set forth: the name and address of the stockholder on whose behalf the submission is made; the number of our shares that are owned beneficially by such stockholder as of the date of the submission; the full name of the proposed candidate; a description of the proposed candidate’s business experience for at least the previous five years; complete biographical information for the proposed candidate; and a description of the proposed candidate’s qualifications as a director. For the proposed candidate to be considered for nomination for the 2008 Annual Meeting of Stockholders, the written communication must be received by January 16, 2008.

Stockholder Communications With the Board of Directors

The Company’s Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to the Company’s General Counsel at 3911 Sorrento Valley Boulevard, San Diego, CA 92121. All communications will be compiled by the General Counsel and submitted to the Board or the individual directors on a periodic basis. These communications will be reviewed the General Counsel, who will determine whether they should be presented to the Board. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications). All communications directed to the Audit Committee in accordance with the Company’s Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters, discussed below, will be treated in accordance with that policy.

Code of Ethics

The Company has adopted the ACADIA Pharmaceuticals Inc. Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on our

website at http://www.acadia-pharm.com. If the Company makes any substantive amendments to this Code of Business Conduct and Ethics or grants any waiver from a provision of the Code to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.

Open Door Policy for Reporting Accounting and Auditing Matters

We have adopted an Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters to facilitate the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, as well as the confidential, anonymous submission by our employees of concerns regarding these matters. The Open Door Policy is available on our website at http://www.acadia-pharm.com.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Audit Committee of our Board of Directors has engaged PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2007 and is seeking ratification of such selection by our stockholders at the annual meeting. PricewaterhouseCoopers LLP has audited our financial statements since 1996. Representatives of PricewaterhouseCoopers LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of PricewaterhouseCoopers LLP to our stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether to retain PricewaterhouseCoopers LLP. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of ACADIA and our stockholders.

To be approved, the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm must receive a “For” vote from the majority of shares present and entitled to vote either in person or by proxy. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes will be counted towards a quorum, but will not be counted for any purpose in determining whether this matter has been approved.

Principal Accountant Fees and Services

The following table provides information regarding the fees billed to us by PricewaterhouseCoopers LLP for the fiscal years ended December 31, 2006 and 2005. All fees described below were approved by the Audit Committee.

Pre-Approval Policies and Procedures.

The Audit Committee has pre-approval polices and procedures in place, pursuant to which services proposed to be performed by our independent registered public accounting firm are pre-approved by the Audit Committee. The policies generally pre-approve specified services in the defined categories of audit services, audit-related services, and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent registered public accounting firm or on an individual service-by-service basis. The pre-approval of non-audit services also has been delegated to the chairperson of the Audit Committee, but each pre-approval decision is reported to the full Audit Committee at its next scheduled meeting. All of the tax fees incurred in 2006 and 2005 were approved in accordance with our pre-approval polices and procedures.

The Audit Committee has determined that the rendering of the services other than audit services by PricewaterhouseCoopers LLP is compatible with maintaining PricewaterhouseCoopers LLP’s independence.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE IN FAVOR OF PROPOSAL 2.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table provides information regarding the beneficial ownership of our common stock as of February 15, 2007 by: (i) each of our directors, (ii) each of our Named Executive Officers (as defined below), (iii) all of our current directors and executive officers as a group, and (iv) each person, or group of affiliated persons, known by us to beneficially own more than five percent of our common stock. The table is based upon information supplied by our officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC. Unless otherwise indicated in the footnotes to the table and subject to community property laws where applicable, we believe that each of the stockholders named in the table has sole voting and investment power with respect to the shares indicated as beneficially owned.

Applicable percentages are based on 29,947,477 shares outstanding on February 15, 2007, adjusted as required by rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on April 16, 2007, which is 60 days after February 15, 2007. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Certain of the options in this table are exercisable at any time but, if exercised, are subject to a lapsing right of repurchase until the options are fully vested.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

Overview

The Compensation Committee of our Board of Directors, composed entirely of independent directors, administers our executive compensation program. The role of the Compensation Committee is to oversee our compensation and benefit plans and policies, to administer our stock plans, and to review and recommend to the full Board of Directors for approval annually all compensation decisions relating to our executive officers.

Compensation Philosophy

Our executive compensation policies are designed to

•

align executive compensation with our business objectives and corporate performance;

•

attract and retain executive officers who contribute to our company’s long-term success;

•

reward and motivate executive officers who contribute to our operating and financial performance; and

•

link executive officer compensation and stockholder interests through the grant of long-term incentives under our stock option plans.

Our Compensation Committee believes that our compensation programs should include short-term and long-term components, including cash and equity-based compensation, and should reward performance as measured against established goals. The Compensation Committee evaluates both performance and compensation to make sure that the compensation provided to executives remains competitive relative to compensation paid by companies of similar size and stage of development operating in the biotechnology industry, taking into account our relative performance and our own strategic goals. Our Compensation Committee considers the total current and potential long-term compensation of each of our executive officers in establishing each element of compensation.

Our Compensation Committee reviews and recommends to the full Board of Directors on an annual basis the compensation to be paid to our chief executive officer and other executive officers. As part of this process, we conduct benchmarking of the aggregate level of our executive compensation, as well as the mix of elements used to compensate our executive officers. In addition, our Compensation Committee has historically taken into account input from other independent members of our Board of Directors and publicly available data relating to the compensation practices and policies of other companies within and outside our industry. While benchmarking may not always be appropriate as a stand-alone tool for setting compensation due to the aspects of our business and objectives that may be unique to us, the Compensation Committee generally believes that gathering this

information is an important part of our compensation-related decision-making process. Our Compensation Committee may retain the services of third-party executive compensation specialists from time to time, as it sees fit, in connection with the establishment of cash and equity compensation and related policies.

The chief executive officer evaluates the performance of other executive officers on an annual basis and makes recommendations to the Compensation Committee with respect to annual salary adjustments, bonuses and annual stock option grants. The Compensation Committee exercises its own discretion in determining salary adjustments and discretionary cash and equity-based awards for our executive officers.

Elements of Executive Compensation

Compensation of our executive officers consists of four principal components: base salary, potential annual incentive bonus, long-term incentives, and post-employment compensation. Since we have been a public company, changes to base salary, awards of incentive bonuses and long-term incentive awards have been generally determined in connection with the regularly scheduled meeting of the Board of Directors in March of each year.

Base Salary. As a general matter, the base salary for each executive officer is initially established through negotiation at the time the officer is hired, taking into account such officer’s qualifications, experience, prior salary, and competitive market salary information for similar positions in the biotechnology industry. The base salaries of our executive officers are reviewed annually and adjustments to each executive officer’s base salary is determined by an assessment of our company’s performance, the performance of each executive officer against his individual job responsibilities including, where appropriate, the impact of such performance on our company’s business results, competitive market conditions for executive compensation for similar positions, and recognizing cost of living considerations.

Annual Incentive Bonuses. In addition to base salary, the Compensation Committee evaluates the performance of, and recommends for approval to our Board of Directors the bonuses payable to, our executive officers on an annual basis. We believe that performance-based cash bonuses play an important role in providing incentives to our executives to achieve defined annual corporate goals. Each year, the Compensation Committee reviews a detailed set of overall corporate performance goals for the current year prepared by management and presented to the full Board of Directors that are intended to apply to the executives’ bonus awards. Annual incentive bonuses are based on each officer’s overall individual performance in his position, his relative contribution to our company’s operational and financial performance during the year, our company’s overall performance in achieving corporate goals, including the achievement of our research and development milestones, including the advancement of our clinical programs and the advancement of our preclinical assets toward clinical development, and competitive market bonus information. The annual incentive bonuses for 2006 were based on, and for 2007 will be based on, targets measured as a percentage of the executives’ individual base salaries as follows: 30% for Uli Hacksell, our Chief Executive Officer; 25% for Roger Mills, our Executive Vice President, Development; 23.5% for Thomas H. Aasen, our Vice President and Chief Financial Officer, and Brian Lundstrom, Senior Vice President, Business Development; and 20% for Bo-Ragnar Tolf, Vice President, Chemistry. The Compensation Committee then has the discretion to recommend bonus amounts from 0 to 150% of the applicable target percentage to our Board of Directors.

Long-Term Incentives. Our long-term incentives are primarily in the form of stock option awards. The objective of these awards is to advance our longer-term interests and those of our stockholders and to complement incentives tied to annual performance. Stock option grants to executives generally are made pursuant to our 2004 Equity Incentive Plan (the “2004 Plan”) at the inception of service and each year thereafter in connection with the regular meeting of the Board of Directors in March of each year. Annual refresher stock option grants to eligible non-executive employees are also made in connection with the March meeting of the Board of Directors. We do not coordinate the grant of stock options to the timing of releases of material non-public information. Stock options only produce value to our executives if the price of our stock appreciates,

thereby directly linking the interests of executives with those of stockholders. The number of stock options granted is based on the executive’s position, the executive’s performance in the prior year, the executive’s potential for continued sustained contributions to our company’s success, and competitive market information. The executive’s stock options are granted with an exercise price based on the fair market value, which is deemed to be the closing price on the trading date prior to grant pursuant to the terms of the 2004 Plan. Stock options granted under the 2004 Plan generally vest over a four-year period (with 25% vesting after one year and the remainder vesting monthly thereafter) and each option is exercisable over a ten-year period following its grant unless the executive’s employment terminates prior to such date. Incentive stock options also include certain other terms necessary to assure compliance with the Internal Revenue Code. The 2004 Plan also permits the issuance of other types of awards, including stock appreciation rights and restricted stock, among others. We have only awarded stock options under the 2004 Plan, but the Compensation Committee, in its discretion, may elect to make different types of awards.

Post-employment Compensation. Our executive officers, who are designated below under “—Summary compensation table,” are entitled to certain severance and change in control benefits, the terms of which are described below under “—Post employment compensation.” We believe these severance and change in control benefits are an essential element of our overall executive compensation package and assist us in recruiting and retaining talented individuals and aligning the executive’s interests with the best interests of the stockholders.

Other Compensation. Consistent with our compensation philosophy, we intend to continue to maintain our current benefits for our executive officers, which are also generally available to employees, including medical, dental, vision and life insurance coverage and 401(k) matching contributions; however, the Compensation Committee in its discretion may revise, amend or add to the officer’s executive benefits.

Section 162(m) Compliance. Section 162(m) of the Internal Revenue Code generally limits the tax deductions a public corporation may take for compensation paid to its executive officers to $1 million per executive per year. Performance based compensation tied to the attainment of specific goals is excluded from the limitation. Our stockholders have previously approved our 2004 Plan, thereby qualifying options and stock appreciation rights under these plans as performance-based compensation exempt from the Section 162(m) limits. Other awards under the 2004 Plan also may qualify as performance-based compensation. In addition, the Compensation Committee intends to evaluate our executive compensation policies and benefit plans during the coming year to determine whether additional actions to maintain the tax deductibility of executive compensation are in the best interest of our stockholders.

(1)

Amounts shown do not reflect amounts actually received by the named individual. The amounts reflect the product of (i) the difference between the market closing price on the date of exercise less the exercise price of the applicable option multiplied by (ii) the number of shares exercised under the applicable option.

Post-Employment Compensation

The amount of compensation payable to each executive officer upon termination of the employment of the executive is shown below. Our Compensation Committee may in its discretion revise, amend or add to the benefits.

Payments made upon termination

Regardless of the manner in which a Named Executive Officer’s employment terminates, the Named Executive Officer is entitled to receive amounts earned during his term of employment, including accrued and unpaid salary and payment in lieu of unused vacation days.

Potential payment under employment arrangements

We have entered into offer letters or employment agreements with each of our Named Executive Officers, setting forth their respective base salary, bonus targets, and other employment benefits. Each Named Executive Officer’s employment is on an “at-will” basis and can be terminated by us or the applicable officer at any time, for any reason and with or without notice, subject, where applicable, to the severance arrangements contained therein. In the event that Dr. Tolf’s employment is terminated by us during its term, we are obligated, except in limited circumstances, to provide Dr. Tolf with six months’ notice. If we terminate the employment of Dr. Hacksell, Mr. Aasen or Dr. Mills for reasons other than cause, we are obligated to pay that executive officer one year’s salary and to continue other benefits the officer may be receiving at the time of termination for the one-year period following termination of employment. If we terminate the employment of Mr. Lundstrom for reasons other than cause, we are obligated to pay him six months’ salary and to continue other benefits he may be receiving at the time of termination for the six-month period following termination of employment. Under the employment offer letters, “cause” means, generally, (a) material failure to competently perform assigned duties for the Company, (b) sustained poor performance of any material aspect of job duties or obligations, (c) dishonesty, gross negligence or other material misconduct, or (d) conviction of, or the entry of a pleading of guilty or nolo contendere to, any crime involving moral turpitude or any felony.

Effect of change in control on stock option awards

In the event the Company is acquired or completes a corporate transaction, any unvested options held by a Named Executive Officer will be immediately vested, subject to the officer’s continued employment for a period of at least six months following the completion of the corporate transaction if so requested by the company. For the purpose of the foregoing, a “corporate transaction” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events:

•

a sale or other disposition of all or substantially all, as determined by the Board of Directors in its discretion, of the consolidated assets of the Company and its subsidiaries;

•

a sale or other disposition of at least 90% of the outstanding securities of the Company;

•

a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or

•

a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of common stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or otherwise.

If a corporate transaction had occurred, effective as of December 31, 2006, the value of the accelerated options to our executive officers would have been: $459,335, $192,344, $61,000, $98,152 and $85,988 to Dr. Hacksell, Mr. Aasen, Dr. Mills, Mr. Lundstrom and Dr. Tolf, respectively, calculated as the sum for each

individual of the products of the (i) the difference between the exercise price of each option deemed accelerated and fair market value on December 31, 2006 multiplied by (ii) the number of shares deemed accelerated under the applicable option.

NonQualified Deferred Compensation

None of our Named Executive Officers participates in or have account balances in nonqualified defined contribution plans or other nonqualified deferred compensation plans maintained by us. Our Compensation Committee may elect to provide our officers and other employees with non-qualified defined contribution or other nonqualified deferred compensation benefits in the future.

Equity Compensation Plan Information

The following table provides certain information as of December 31, 2006, with respect to all of our equity compensation plans in effect on that date.


	Number of securities to be issued upon exercise of outstanding options, warrants and rights (a)	Weighted-average exercise price of outstanding options, warrants and rights (b)		Number of securities remaining available for issuance under equity compensation plans (excluding securities reflected in column (a)) (c)
Equity compensation plans approved by stockholders(1)	2,820,389	$	6.62	844,997
Equity compensation plans not approved by stockholders(2)	—		—	—
Total	2,820,389	$	6.62	844,997

(1)

Includes our 1997 Stock Option Plan, the 2004 Plan, and our 2004 Employee Stock Purchase Plan (the “ESPP”). 297,424 shares under column (c) are attributable to our ESPP. Each of our 2004 Plan and our ESPP contain so called “evergreen” provisions providing for annual increases to their respective share reserves in connection with the 2007 Annual Meeting of Stockholders. The number of shares to be added to our 2004 Plan will be equal to the least of: (i) 1,078,950, which is three percent of the number of shares of our outstanding common stock as April 16, the record date for the 2007 Annual Meeting of Stockholders; (ii) 750,000; or (iii) an amount determined for such year by our board of directors. The number of shares to be added to our ESPP will be equal to the least of: (i) 359,650, which is one percent of our outstanding common stock as of April 16, the record date for the 2007 Annual Meeting of Stockholders; (ii) 150,000; or (iii) an amount determined for such year by our Board of Directors.

(2)	As of December 31, 2006, we did not have any equity compensation plans that were not approved by our stockholders.

Director Compensation

We provide each of our non-employee directors cash compensation in the form of an annual retainer of $15,000, plus an additional $12,500 for the Chairman of the Board of Directors and an additional $5,000 for the committee chairpersons. The annual retainers may, at the election of the individual director, be converted into an option to purchase a number of shares of stock equal to the quotient of three times the retainer amount to be converted, divided by the exercise price for such option, as determined in accordance with the terms of the 2004 Plan. The 2004 Plan provides that the exercise price for options are equal to the closing price for the Company’s common stock on the trading day immediately prior to option grant date. Directors receive $1,000 per board meeting attended in person and $250 per meeting attended telephonically. Committee members receive $750 per regular meeting and $500 per special telephonic meeting, and the chairpersons receive twice those amounts. We also reimburse our non-employee directors for their reasonable expenses incurred in attending meetings of our Board of Directors and committees of the Board.

Each of our non-employee directors also receives stock option grants under our 2004 Plan. Options granted to our non-employee directors are intended by us not to qualify as incentive stock options under the Internal Revenue Code of 1986, as amended. These option grants are non-discretionary.

Any person who joins the Board of Directors as a non-employee director will receive an option to purchase 15,000 shares of common stock upon his or her election. In addition, any person who is a non-employee director on the date of each annual meeting of our stockholders will be automatically granted, on the annual meeting date, an option to purchase 10,000 shares of common stock. The annual retainer amount and option grant may be pro rated for a director that joins the Board other than at the first meeting of the Board following the annual meeting of stockholders. In addition, directors may elect to convert their retainer amounts, in whole or in part, into options under the 2004 Plan with an aggregate exercise price equal to three times the amount elected for conversion.

Initial grants (i.e., those made upon a non-employee director’s election to our Board of Directors) vest over two years following the date of grant, and annual grants, including any retainer amounts that are converted, vest at the rate of 1/4th each quarter after the date of grant. In general, the term of stock options granted under the 2004 Plan may not exceed ten years.

Unless the terms of an director’s stock option agreement provide for earlier or later termination, if an optionholder’s service relationship with us, or any affiliate of ours, ceases for any reason, the optionholder may exercise any vested options up to three years from cessation of service.

The following table shows for the fiscal year ended December 31, 2006 certain information with respect to the compensation of all persons who served as directors of the Company during the year, other than Dr. Hacksell and Dr. Brann, who are Named Executive Officers and received no additional compensation for their services as directors:

TRANSACTIONS WITH RELATED PERSONS

Related-Person Transactions policy and Procedures

The charter of the Audit Committee states that it will review, consideration and approval or ratification of “related-persons transactions.” A “related-person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company and any “related person” are participants involving an amount that exceeds $120,000. Transactions involving compensation for services provided to the Company as an employee, director, consultant or similar capacity by a related person are not covered. A related person is any executive officer, director, or more than 5% stockholder of the Company, including any of their immediate family members, and any entity owned or controlled by such persons.

Where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-person transaction to the Audit Committee (or, where Audit Committee approval would be inappropriate, to another independent body of the board) for consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to the Company of the transaction and whether any alternative transactions were available. To identify related-person transactions in advance, the Company relies on information supplied by its executive officers and directors. In considering related-person transactions, the Committee takes into account the relevant available facts and circumstances including, but not limited to (a) the risks, costs and benefits to the Company, (b) the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated, (c) the terms of the transaction, (d) the availability of other sources for comparable services or products and (e) the terms available to or from, as the case may be, unrelated third parties or to or from employees generally. In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval. In determining whether to approve, ratify or reject a related-person transaction, the Committee will look at, in light of known circumstances, whether the transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders, as the Committee determines in the good faith exercise of its discretion.

Certain Related-Person Transactions

On January 10, 2005, we entered into a License, Option and Collaboration Agreement with Sepracor Inc. In connection with the collaboration, Sepracor has purchased an aggregate of 1,890,422 shares of the Company’s common stock for an aggregate of $20 million in two $10 million tranches. The first tranche of 1,077,029 shares closed on January 13, 2005 and the second tranche of 813,393 shares closed on January 13, 2006. Pursuant to the collaboration agreement, Sepracor had provided research funding to the Company in the aggregate amount of $6.7 million through March 31, 2007.

Until April 2004, one of our directors, Dr. Kaplan, was an executive officer and board member of Allergan with whom we have ongoing collaborations.

One of our directors, Alan G. Walton, is the General Partner of Oxford Bioscience Partners IV and mRNA Fund II L.P., which are affiliated funds and which together hold more than 5% of our outstanding stock.

In October 2006, the Company entered into an agreement to provide initial seed funding to help establish Abbey Pharmaceuticals, Inc. (“Abbey”), a startup biotechnology company focused on medications for substance abuse. Abbey is led by Mark R. Brann, the Company’s former President, Chief Scientific Officer and Director. The Company has agreed to increase its investment in Abbey to an aggregate of $1 million upon Abbey’s satisfaction of certain conditions, including completion of an external equity financing. Once Abbey has obtained equity financing, the Company may collaborate with Abbey in the field of substance abuse.

In connection with Dr. Brann’s resignation, on October 20, 2006, ACADIA entered into a separation agreement and a consultant agreement with Dr. Brann. Pursuant to the separation agreement, Dr, Brann is entitled to certain benefits, including reimbursement of his COBRA premiums through December 31, 2008. Pursuant to the consultant agreement, Dr. Brann will provide consulting services to ACADIA focused on ACADIA’s technology and related scientific applications. Copies of the separation agreement and consultant agreement were included as exhibits to the Company’s Current Report on Form 8-K, which was filed with the SEC on October 23, 2006.

Our bylaws provide that we will indemnify our directors and executive officers, and may indemnify other officers, employees and other agents, to the fullest extent permitted by law. Our bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in connection with their services to us, regardless of whether our amended and restated bylaws permit such indemnification. We have obtained a policy of directors’ and officers’ liability insurance.

We have entered, and intend to continue to enter, into indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our bylaws. These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers, or any of our subsidiaries or any other company or enterprise to which the person provides services at our request.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding”, potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are stockholders of ACADIA Pharmaceuticals Inc. will be householding our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your broker. Direct your written request to ACADIA Pharmaceuticals Inc., 3911 Sorrento Valley Boulevard, San Diego, California 92121, Attn: Investor Relations, or contact Investor Relations at (858) 558-2871. Stockholders who currently receive multiple copies of the proxy statement at their addresses and would like to request householding of their communications should contact their brokers.

OTHER MATTERS

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.
