PROXY STATEMENT FOR THE 2016 ANNUAL MEETING OF STOCKHOLDERS

---

March 8, 2016

INFORMATION ABOUT SOLICITATION AND VOTING

        The accompanying proxy is solicited on behalf of the board of directors of Corium International, Inc. ("Corium") for use at Corium's 2016 Annual Meeting of Stockholders ("Annual Meeting") to be held on March 8, 2016, at 1:00 p.m. (Pacific Time), and any adjournment or postponement thereof. This proxy statement for the 2016 Annual Meeting ("Proxy Statement") and the accompanying form of proxy were first mailed to stockholders on or about January 19, 2016. An annual report for the year ending September 30, 2015 is enclosed with this Proxy Statement. An electronic copy of this Proxy Statement and annual report on Form 10-K are available at www.proxyvote.com.

GENERAL INFORMATION ABOUT THE ANNUAL MEETING

Purpose of the Annual Meeting

        At the Annual Meeting, stockholders will act upon the proposals described in this Proxy Statement.

Record Date; Quorum

        Only holders of record of our common stock at the close of business on January 8, 2016 ("Record Date") will be entitled to vote at the Annual Meeting. At the close of business on the Record Date, we had 22,219,413 shares of common stock outstanding and entitled to vote.

        The holders of a majority of the voting power of the shares of stock entitled to vote at the Annual Meeting as of the Record Date must be present at the Annual Meeting in order to hold the Annual Meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the Annual Meeting if you are present and vote in person at the Annual Meeting or if you have properly submitted a proxy.

Voting Rights; Required Vote

        In deciding all matters at the Annual Meeting, each holder of shares of our common stock is entitled to one vote for each share of common stock held as of the close of business on the Record Date. We do not have cumulative voting rights for the election of directors. You may vote all shares owned by you as of the Record Date, including (i) shares held directly in your name as the stockholder of record and (ii) shares held for you as the beneficial owner in street name through a broker, bank, trustee or other nominee.

        Stockholder of Record: Shares Registered in Your Name.    If, on the Record Date, your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the Annual Meeting or vote by telephone, by Internet or by filling out and returning the proxy card.

        Beneficial Owner: Shares Registered in the Name of a Broker or Nominee.    If, on the Record Date, your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your nominee on how to vote the shares held in your account, and your nominee has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. However, the organization that holds your shares is considered the stockholder of record for purposes of voting at the Annual Meeting. Because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the Annual Meeting.

Table of Contents

        Each director will be elected by a plurality of the votes cast, which means that the three individuals nominated for election to the board of directors at the Annual Meeting receiving the highest number of "FOR" votes will be elected. You may either vote "FOR" one or any of the nominees or "WITHHOLD" your vote with respect to one or any of the nominees. Ratification of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2016 will be obtained if the number of votes cast "FOR" the proposal at the Annual Meeting exceeds the number of votes "AGAINST" the proposal.

        Broker non-votes occur when shares held by a broker for a beneficial owner are not voted either because (i) the broker did not receive voting instructions from the beneficial owner, or (ii) the broker lacked discretionary authority to vote the shares. Abstentions occur when shares present at the Annual Meeting are marked "abstain." Broker non-votes and abstentions are counted for purposes of determining whether a quorum is present, but have no effect on the outcome of the matters voted upon. Under the listing rules and interpretations of The Nasdaq Stock Market LLC ("Nasdaq"), "non-routine" matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors, executive compensation and certain corporate governance proposals, even if management-supported. At our Annual Meeting, only ratification of the appointment of our independent registered public accounting firm is considered a "routine" matter. Note that if you are a beneficial holder and do not provide specific voting instructions to your broker, the broker that holds your shares will not have discretionary authority to vote on the election of directors. Accordingly, we encourage you to provide voting instructions to your broker, whether or not you plan to attend the Annual Meeting.

Recommendations of the Board of Directors on Each of the Proposals Scheduled to be Voted on at the Annual Meeting

        The board of directors recommends that you vote "FOR" each of the Class II directors named in this Proxy Statement ("Proposal 1") and "FOR" the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2016 ("Proposal 2"). None of the directors or executive officers has any substantial interest in any matter to be acted upon, other than elections to office with respect to the directors so nominated.

Voting Instructions; Voting of Proxies

        If you are a stockholder of record, you may:

•

vote in person — we will provide a ballot to stockholders who attend the Annual Meeting and wish to vote in person;



•

vote via telephone or Internet — in order to do so, please follow the instructions shown on your proxy card; or



•

vote by mail — complete, sign and date the proxy card enclosed herewith and return it before the Annual Meeting in the envelope provided.

        Votes submitted by telephone or Internet must be received by 11:59 p.m. (Eastern Time) on March 7, 2016. Submitting your proxy, whether via the Internet, by telephone, or by mail, will not affect your right to vote in person should you decide to attend the Annual Meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct it how to vote your shares. You may either vote "FOR" all of the nominees to the board of directors, or you may withhold your vote from any nominee you specify. For any other matter to be voted on you may vote "FOR" or "AGAINST" or "ABSTAIN" from voting. Your vote is important. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure that your vote is counted.

        All proxies will be voted in accordance with the instructions specified on the proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the Annual Meeting, your shares will be voted in accordance with the recommendations of our board of directors stated above.

Table of Contents

        If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute "broker non-votes" (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, shares that constitute broker non-votes will be counted for the purpose of establishing a quorum for the Annual Meeting.

        If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each proxy card and vote each proxy card by telephone. If you are voting by mail, please complete, sign and return each proxy card to ensure that all of your shares are voted.

Expenses of Soliciting Proxies

        Corium will pay the expenses of soliciting proxies. Following the original mailing of the soliciting materials, Corium and its agents, including directors, officers and other employees, without additional compensation, may solicit proxies by mail, electronic mail, telephone, facsimile, by other similar means or in person. Following the original mailing of the soliciting materials, Corium will request brokers, custodians, nominees and other record holders to forward copies of the soliciting materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, Corium, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials through the Internet, you are responsible for any Internet access charges you may incur.

Revocability of Proxies

        A stockholder who has given a proxy may revoke it at any time before it is exercised at the Annual Meeting by:

•

delivering to the Corporate Secretary of Corium (by any means, including facsimile) a written notice stating that the proxy is revoked;



•

signing and delivering a proxy bearing a later date;



•

voting again by telephone or Internet; or



•

attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).

Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions.

Voting Results

        Voting results will be tabulated and certified by the inspector of elections appointed for the Annual Meeting. The preliminary voting results will be announced at the Annual Meeting. The final results will be tallied by the inspector of elections and filed with the Securities and Exchange Commission ("SEC") in a current report on Form 8-K within four business days of the Annual Meeting.

BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD; CORPORATE GOVERNANCE STANDARDS AND DIRECTOR INDEPENDENCE

        Corium is strongly committed to good corporate governance practices. These practices provide an important framework within which our board of directors and management can pursue our strategic objectives for the benefit of our stockholders.

Corporate Governance Guidelines

        Our board of directors has adopted corporate governance guidelines that set forth the role of the board of directors, director independence standards, board structure and functions, director selection considerations and other policies for the governance of Corium ("Corporate Governance Guidelines"). Our Corporate Governance Guidelines are available on the Investors section of our website, which is located at http://ir.coriumgroup.com,

by clicking on "Corporate Governance Guidelines," under "Corporate Governance." Our nominating and corporate governance committee reviews the Corporate Governance Guidelines periodically, and recommends changes to our board of directors as warranted.

Board Leadership Structure

        Our Corporate Governance Guidelines provide that our board of directors shall be free to choose its chairperson in any way that it considers in the best interests of our company, and that the nominating and corporate governance committee shall periodically consider the leadership structure of our board of directors and make such recommendations to the board of directors with respect thereto as the nominating and corporate governance committee deems appropriate. Our Corporate Governance Guidelines also provide that, when the positions of chairperson and Chief Executive Officer are held by the same person, the independent directors may designate a "lead independent director." In cases in which the chairperson and Chief Executive Officer are the same person, the chairperson schedules and sets the agenda for meetings of the board of directors, and chairs such meetings. If the chairperson is not present, the lead independent director chairs such meetings. In addition, the responsibilities of the lead independent director include: presiding over executive sessions of independent directors; serving as a liaison between the chairperson and the independent directors; being available, under appropriate circumstances, for consultation and direct communication with stockholders; and performing such other functions and responsibilities as requested by the board of directors from time to time.

        Our board of directors believes that Corium and our stockholders are best served by having David L. Greenwood serve as Chairman. Our board of directors believes that the current board leadership structure, coupled with a strong emphasis on board independence, provides effective independent oversight of management while allowing the board and management to benefit from Mr. Greenwood's extensive financial and business expertise in the biotechnology industry. Robert W. Thomas currently serves as lead independent director to coordinate the activities of the non-employee directors and to perform other duties and responsibilities as our board of directors may from time to time determine. Our board of directors believes that its independence and oversight of management is maintained effectively through this leadership structure, the composition of the board of directors and sound corporate governance policies and practices.

Our Board of Directors' Role in Risk Oversight

        Our board of directors, as a whole, has responsibility for risk oversight, although the committees of our board of directors oversee and review risk areas that are particularly relevant to them. The risk oversight responsibility of our board of directors and its committees is supported by our management reporting processes, which are designed to provide visibility to the board of directors and to our personnel that are responsible for risk assessment and information about the identification, assessment and management of critical risks and management's risk mitigation strategies. These areas of focus include, but are not limited to, competitive, economic, operational, financial (accounting, credit, liquidity and tax), legal, regulatory, compliance and reputational risks.

        Each committee of the board of directors meets in executive session with key management personnel and representatives of outside advisors to oversee risks associated with their respective principal areas of focus. The audit committee reviews our major financial risk exposures and the steps management has taken to monitor and control such exposures, including our risk assessment and risk management policies and guidelines. The compensation committee reviews risks and exposures associated with compensation programs and arrangements, including incentive plans. The nominating and corporate governance committee, together with the audit committee, reviews our major legal compliance risk exposures and monitors the processes put in place by management to mitigate these exposures, including our legal risk assessment and legal risk management policies and guidelines.

Director Independence

        Our board of directors determines the independence of our directors by applying the applicable Nasdaq rules and listing standards. These provide that a director is independent only if the board affirmatively determines that the director does not have a relationship with the company which, in the opinion of the board of

4

Table of Contents

directors, would interfere with the exercise of his or her independent judgment in carrying out the responsibilities of a director. They also specify various relationships that preclude a determination of director independence. Such relationships may include employment, commercial, accounting, family and other business, professional and personal relationships.

        Applying these standards, the board annually reviews the independence of our directors, taking into account all relevant facts and circumstances. In its most recent review, our board of directors considered, among other things, the relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

        Based upon this review, our board of directors has determined that all of the non-employee members of our board (other than Mr. Greenwood) are currently independent as determined under applicable Nasdaq rules and listing standards. All members of our audit committee, compensation committee and nominating and corporate governance committee must be independent directors under the applicable Nasdaq rules and listing standards. Members of the audit committee also must satisfy a separate SEC independence requirement, which provides that (i) they may not accept directly or indirectly any consulting, advisory or other compensatory fee from Corium or any of its subsidiaries other than their directors' compensation, and (ii) they may not be an affiliated person of Corium or any of its subsidiaries. Members of the compensation committee also must satisfy a separate SEC independence requirement and a related Nasdaq listing standard with respect to their affiliation with Corium and any consulting, advisory or other fees they may have received from Corium. Our board of directors has determined that all members of our audit committee, compensation committee and nominating and corporate governance committee are independent and satisfy the relevant SEC and Nasdaq independence requirements for such committees.

Board Committees

        Our board of directors has established an audit committee, a compensation committee, a nominating and corporate governance committee and a technology and product development committee. The composition and responsibilities of each committee are described below. Each of these committees, with the exception of the technology and product development committee, has a written charter approved by our board of directors. Copies of the charters for the audit committee, compensation committee and nominating and corporate governance committee are available, without charge, upon request in writing to Corium International, Inc., 235 Constitution Drive, Menlo Park, California 94025, Attn: Corporate Secretary or by clicking on "Corporate Governance" in the Investors section of our website, http://ir.coriumgroup.com. Members serve on these committees until their resignations or until otherwise determined by our board of directors.

Audit Committee

        Our audit committee is comprised of Eric H. Bjerkholt, who is the chair of the audit committee, Dr. Bhaskar Chaudhuri and Dr. Paul Goddard. The members of our audit committee meet the requirements for independence under current Nasdaq and SEC rules, regulations and listing standards. Each member of our audit committee is financially literate as required by the Nasdaq listing standards. In addition, our board of directors has determined that Mr. Bjerkholt is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities Act of 1933, as amended. This designation does not impose on him any duties, obligations or liabilities that are greater than are generally imposed on members of our audit committee and our board of directors. Our audit committee is directly responsible for, among other things:

•

selecting the independent registered public accounting firm to audit our financial statements, discussing the scope and results of the audit with the independent registered public accounting firm and reviewing, with management and that firm, our interim and year-end operating results;



•

ensuring the independence of the independent registered public accounting firm;



•

establishing procedures for employees to anonymously submit concerns about questionable accounting or audit matters;



•

considering the adequacy of our internal controls and internal audit function;

5

Table of Contents

•

reviewing material related party transactions or those that require disclosure; and



•

approving or, as permitted, pre-approving all audit and non-audit services to be performed by the independent registered public accounting firm.

Compensation Committee

        Our compensation committee is comprised of Mr. Thomas, who is the chair of the compensation committee, Mr. Ronald Eastman and Dr. Goddard. The composition of our compensation committee meets the requirements for independence under current Nasdaq and SEC rules, regulations and listing standards. Each member of this committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended ("Exchange Act"), an outside director, as defined pursuant to Section 162(m) of the Code and is "independent" as defined in Section 5605(a)(2) of the Nasdaq rules and Rule 10C-1 promulgated under the Exchange Act. The purpose of our compensation committee is to discharge the responsibilities of our board of directors relating to compensation of our executive officers. Our compensation committee is responsible for, among other things:

•

reviewing and approving, or recommending that our board of directors approve (if the compensation committee or legal counsel determines that such approval by the board of directors is desirable or required by applicable law or the Nasdaq rules) the compensation of our executive officers and the other terms of any compensatory agreements with our executive officers;



•

reviewing and recommending to our board of directors the compensation of our non-employee directors;



•

administering our stock and equity incentive plans;



•

reviewing and approving, or making recommendations to our board of directors with respect to, incentive compensation and equity plans; and



•

reviewing our overall compensation philosophy.

        The compensation committee may take into account the recommendations of the Chief Executive Officer with respect to compensation of the other executive officers, and the recommendations of the board of directors or any member of the board of directors with respect to compensation of the Chief Executive Officer and other executive officers.

        The compensation committee engaged an independent executive compensation consulting firm, Radford, an AON Hewitt Company ("Radford"), to evaluate our executive compensation program and practices and to provide advice and ongoing assistance on executive compensation matters for fiscal 2015. Specifically, Radford was engaged to:

•

provide compensation-related data for a peer group of companies to serve as a basis for assessing competitive compensation practices;



•

review and assess our current director, Chief Executive Officer and other executive officer compensation policies and practices and equity profile relative to market practices;



•

review and assess our current executive compensation program relative to market to identify any potential changes or enhancements to be brought to the attention of the compensation committee; and



•

review market practices on employee stock purchase plans and other equity programs.

        Representatives of Radford met informally with the chair of the compensation committee and attended the regular meetings of the compensation committee.. During fiscal 2015, Radford worked directly with the compensation committee (and not on behalf of management) to assist the committee in satisfying its responsibilities and undertook no projects for management without the committee's prior approval. The compensation committee has determined that none of the work performed by Radford during fiscal 2015 raised any conflict of interest.

Nominating and Corporate Governance Committee

        Our nominating and governance committee is comprised of Dr. Chaudhuri, who is the chair of the nominating and governance committee, Mr. Eastman and Mr. Thomas. The composition of our nominating and governance committee meets the requirements for independence under current Nasdaq rules and listing standards. Our nominating and governance committee is responsible for, among other things:

•

identifying and recommending candidates for membership on our board of directors;



•

developing, reviewing and recommending our Corporate Governance Guidelines and policies;



•

reviewing proposed waivers of the code of business conduct and ethics for directors and code of business conduct and ethics for employees;



•

overseeing the evaluation of our board of directors on an annual basis; and

assisting our board of directors on corporate governance matters.

Technology and Product Development Committee

        Our technology and product development committee is comprised of Dr. Phyllis Gardner, who is the chair of the technology and product development committee, Dr. Chaudhuri, and Dr. Ivan Gergel. The board of directors formed this committee for the purpose of advising on technology and product development matters and other related matters as determined by the board of directors from time to time.

Compensation Committee Interlocks and Insider Participation

        None of our executive officers has served as a member of the board of directors, or as a member of the compensation or similar committee, of any entity that has one or more executive officers who served on our board of directors or compensation committee during fiscal 2015.

Code of Business Conduct and Ethics

        We have adopted a Code of Business Conduct and Ethics for Directors ("Code of Conduct for Directors") and a Code of Business Conduct and Ethics for Employees ("Code of Conduct for Employees"). Our Code of Conduct for Directors and our Code of Conduct for Employees are posted on the Investors section of our website located at http://ir.coriumgroup.com by clicking on "Corporate Governance." Any amendments or waivers of our Code of Conduct for Directors or our Code of Conduct for Employees pertaining to a member of our board of directors or one of our executive officers will be disclosed on our website at the above-referenced address.

Board and Committee Meetings and Attendance

        Our board of directors and its committees meet throughout the year on a set schedule, and also hold special meetings and act by written consent from time to time. During fiscal 2015, our board of directors met seven times, including telephonic meetings, the audit committee held six meetings, the compensation committee held five meetings and the nominating and corporate governance committee held three meetings. None of the directors attended fewer than 75% of the aggregate of the total number of meetings held by the board of directors and the total number of meetings held by all committees of the board of directors on which such director served (during the period that such director served on the board of directors and any committee).

Board Attendance at Annual Stockholders' Meeting

        Our policy is to invite and encourage each member of our board of directors to be present at our annual meetings of stockholders. At our annual meeting of our stockholders in 2015, five of the directors who were on the board of directors as of the date of the meeting attended the meeting.

NOMINATIONS PROCESS AND DIRECTOR QUALIFICATIONS

Nomination to the Board of Directors

        Candidates for nomination to our board of directors are selected by our board of directors based on the recommendation of the nominating and corporate governance committee in accordance with the committee's charter, our certificate of incorporation and bylaws, our Corporate Governance Guidelines and the criteria adopted by the board of directors regarding director candidate qualifications. In recommending candidates for nomination, the nominating and corporate governance committee considers candidates recommended by directors, officers, employees, stockholders and others, using the same criteria to evaluate all candidates. Evaluations of candidates generally involve a review of background materials, internal discussions and interviews with selected candidates as appropriate and, in addition, the committee may engage consultants or third-party search firms to assist in identifying and evaluating potential nominees.

        Additional information regarding the process for properly submitting stockholder nominations for candidates for membership on our board of directors is set forth below under "Stockholder Proposals to Be Presented at Next Annual Meeting."

Director Qualifications

        With the goal of developing a diverse, experienced and highly-qualified board of directors, the nominating and corporate governance committee is responsible for developing and recommending to the board of directors the desired qualifications, expertise and characteristics of members of our board of directors, including the specific minimum qualifications that the committee believes must be met by a committee-recommended nominee for membership on the board of directors and any specific qualities or skills that the committee believes are necessary for one or more of the members of the board of directors to possess.

        Since the identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors, and will be significantly influenced by the particular needs of the board of directors from time to time, our board of directors has not adopted a specific set of minimum qualifications, qualities or skills that are necessary for a nominee to possess, other than those that are necessary to meet U.S. legal, regulatory and Nasdaq listing requirements and the provisions of our certificate of incorporation, bylaws, Corporate Governance Guidelines and charters of the board committees. In addition, neither the board of directors nor the nominating and corporate governance committee has a formal policy with regard to the consideration of diversity in identifying nominees. When considering nominees, the nominating and corporate governance committee may take into consideration many factors including, among other things, a candidate's independence, integrity, skills, financial and other expertise, breadth of experience, knowledge about our business or industry and ability to devote adequate time and effort to responsibilities of the board of directors in the context of its existing composition. Through the nomination process, the nominating and corporate governance committee seeks to promote board membership that reflects a diversity of business experience, expertise, viewpoints, personal backgrounds and other characteristics that are expected to contribute to the board of directors' overall effectiveness. The brief biographical description of each director set forth in Proposal 1 below includes the primary individual experience, qualifications, attributes and skills of each of our directors that led to the conclusion that each director should serve as a member of our board of directors at this time.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

        Our board of directors currently consists of nine directors and is divided into three classes. Each class serves for three years, with the terms of office of the respective classes expiring in successive years. Directors in Class II will stand for election at our Annual Meeting to be held on March 8, 2016.

With respect to our Chief Technology Officer and Vice President of Research and Development (Dr. Singh) only, these benefits are in effect for three years after the date of his severance benefits letter, subject to extension by written agreement signed by Dr. Singh and one of our authorized officers.

        In addition, in the event of a termination of the employment of Mr. Staple or Mr. Breuil by us without "cause" or by such officer for "good reason" (as such terms are defined in their respective offer letters) within one year following a liquidation event (or with respect to Mr. Breuil, prior to a liquidation event but after Corium enters into a definitive agreement for a transaction that, if consummated, would constitute a liquidation event) the then outstanding and unexercisable options held by such officer will vest with respect to 100% of the shares.

RELATED PARTY TRANSACTIONS

        Other than compensation arrangements, including the executive officer and director compensation arrangements discussed above under "Executive Compensation" and "Proposal No. 1 — Election of Directors — Director Compensation," respectively, since October 1, 2014, there has not been, nor is there currently proposed, any transaction or series of similar transactions to which we were or will be a party in which the amount involved exceeds $120,000 and in which our directors, executive officers, former directors, former executive officers, director nominees and holders of more than 5% of our common stock, or other persons as may be required to be disclosed pursuant to Item 404 of Regulation S-K, had or will have a direct or indirect material interest. We refer to such persons collectively as related parties.

Review, Approval or Ratification of Transactions with Related Parties

        The charter of our audit committee requires that any transaction with a related party that must be reported under applicable rules of the SEC, other than compensation related matters, must be reviewed and approved or ratified by our audit committee. Our related party transactions policy does not permit our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of our common stock and any members of the immediate family of and any entity affiliated with any of the foregoing persons, to enter into any transaction with us, irrespective of the amounts involved, without first submitting the transaction to our Chief Financial Officer for his determination of what approvals are required under the policy, and the review and approval of the chair of our audit committee, or another member of our audit committee in the event it is inappropriate for the chair of our audit committee to review such transaction due to a conflict of interest. In approving or rejecting any such proposal, our approving committee member will consider the relevant and available facts and circumstances, including, but not limited to, the related party's relationship to Corium and interest in the transaction, the material facts of the proposed transaction, including the proposed aggregate value of such transaction, the rationale for the proposed transaction and the impact on a director's independence in the event the related party is a director, immediate family member of a director or an entity with which a director is affiliated. Our approving committee member shall approve only those transactions with related parties that, in light of known circumstances, are in or are not inconsistent with, the best interests of Corium and our stockholders, as determined in such member's good faith exercise of discretion.
