Item 1.
|
Security and Issuer.
|
The class of equity securities to which this statement relates is the shares of common stock, par value $0.001 per share (“Shares”), of Supernus Pharmaceuticals, Inc. (the “Issuer”). The Shares are listed on the NASDAQ Global Market under the ticker symbol “SUPN.” The Issuer’s principal offices are located at 1550 East Gude Drive, Rockville, Maryland 20850.
|
Item 2.
|
Identity and Background.
|
(a) This Statement is being filed by OrbiMed Advisors LLC, a limited liability company organized under the laws of Delaware (“Advisors”), OrbiMed Capital GP II LLC, a limited liability company organized under the laws of Delaware (“GP II”), and Samuel D. Isaly (“Isaly”), an individual (collectively, the “Reporting Persons”).
(b) — (c) Advisors, a registered investment adviser under the Investment Advisers Act of 1940, as amended, is the sole managing member of GP II, as more particularly described in Items 5 and 6 below. Advisors has its principal offices at 601 Lexington Avenue, 54th Floor, New York, NY 10022.
GP II is the general partner of OrbiMed Private Investments II, LP (“OPI II”) and OrbiMed Private Investments II (QP), LP (“OPI II QP”), two limited partnerships that hold securities of the Issuer, as more particularly described in Items 5 and 6 below. GP II has its principal offices at 601 Lexington Avenue, 54th Floor, New York, NY 10022.
Isaly is the managing member of, and owns a controlling interest in, Advisors.
In accordance with the provisions of General Instruction C to Schedule 13D, the information required by Item 2 of Schedule 13D with respect to each person managing or otherwise controlling Advisors and GP II is set forth on Schedules I and II hereto and incorporated by reference herein.
(d) — (e) During the last five years, neither the Reporting Persons nor any person named in Schedules I or II have been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
|
Item 3.
|
Source and Amount of Funds or Other Considerations.
|
Not applicable.
|
Item 4.
|
Purpose of Transaction.
|
As described more fully in Item 5 below, this statement relates to the disposition of Shares by the Reporting Persons. The Shares initially had been acquired (and those that continue to be held, are held) by the Reporting Persons for the purpose of making an investment in the Issuer and not with the intention of acquiring control of the Issuer’s business on behalf of OPI II and OPI II QP.
The Reporting Persons from time to time intend to review their investment in the Issuer on the basis of various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s Shares in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time. If the Reporting Persons believe that further investment in the Issuer is attractive, whether because of the market price of the Issuer’s Shares or otherwise, they may acquire Shares or other securities of the Issuer either in the open market or in privately negotiated transactions. Similarly, depending on market and other factors, the Reporting Persons may determine to dispose of some or all of the Shares currently owned by the Reporting Persons or otherwise acquired by the Reporting Persons either in the open market or in privately negotiated transactions.
5
Except as set forth above, the Reporting Persons have not formulated any plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer, (b) an extraordinary corporate transaction involving the Issuer or any of its subsidiaries, (c) a sale or transfer of a material amount of the assets of the Issuer or any of its subsidiaries, (d) any change in the present Board of Directors or management of the Issuer, (e) any material change in the Issuer’s capitalization or dividend policy, (f) any other material change in the Issuer’s business or corporate structure, (g) any change in the Issuer’s charter or bylaws or other instrument corresponding thereto or other action which may impede the acquisition of control of the Issuer by any person, (h) causing a class of the Issuer’s securities to be deregistered or delisted, (i) a class of equity securities of the Issuer becoming eligible for termination of registration or (j) any action similar to any of those enumerated above.
|
Item 5.
|
Interest in Securities of the Issuer.
|
(a) — (b) As of this date of this filing, the Reporting Persons may be deemed, directly or indirectly, including by reason of their mutual affiliation, to be the beneficial owners of the Shares held by OPI II and OPI II QP. As of the date of this filing, OPI II directly holds 1,818,800 Shares and OPI II QP directly holds 681,200 Shares.
Advisors, pursuant to its authority as the sole managing member of GP II, the general partner of OPI II and OPI II QP, may be deemed to indirectly beneficially own the securities of the Issuer held by OPI II and OPI II QP, which represent an aggregate of 2,500,000 Shares and constitute approximately 8.07% of the outstanding Shares. Isaly, pursuant to his authority as the managing member of, and owner of a controlling interest in, Advisors, may also be deemed to indirectly beneficially own the foregoing securities of the Issuer attributable to Advisors.
GP II, pursuant to its authority as the general partner of OPI II and OPI II QP, may be deemed to indirectly beneficially own the securities of the Issuer held by OPI II and OPI II QP, which represent an aggregate of 2,500,000 Shares and constitute approximately 8.07% of the outstanding Shares.
As a result of the agreements and relationships described in Item 2 above and Item 6 below, the Reporting Persons have shared discretionary power to direct the vote and the disposition of the securities of the Issuer held by OPI II and OPI II QP.
