On December 28, 2009 OrbiMed Capital GP III LLC and OrbiMed Advisors LLC made an in-kind distribution of 1,800,153 shares of  Common Stock to investors in Caduceus and Associates. Concurrently, Associates transferred 4,947 shares of Common Stock to OrbiMed Advisors LLC. On January 7, 2010 OrbiMed Advisors LLC made an in-kind distribution to its members of 4,947 shares of Common Stock.
 
As a result of the transactions described in this Item 3, the Reporting Persons are beneficial owners of approximately 12.86% of the outstanding Shares of the Issuer.  Isaly, as the owner of a controlling interest in both OrbiMed Advisors LLC and OrbiMed Capital GP III LLC, is the beneficial owner of approximately 12.86% of the outstanding Shares of the Issuer.

None of the Reporting Persons have acquired or disposed of any additional Shares of the Issuer since January 7, 2010.
 
Item 4.
Purpose of Transaction.
 
Of the in-kind distribution of the Common Stock made to investors in Caduceus on December 28, 2009, as described in Item 3., 3,406 shares were allocated to Michael B. Sheffery, a director of the Issuer, who also is a partner of OrbiMed Advisors LLC and of OrbiMed Capital GP III LLC. Of the in-kind distribution of the Common Stock made by OrbiMed Advisors LLC to its members on January 7, 2010 as described in Item 3., 466 shares were allocated to Mr. Sheffery. As a result of these transactions, Mr. Sheffery holds directly 3,872 shares of Common Stock of the issuer.
 
Prior to the close of June 8, 2007, Michael B. Sheffery a director of the Issuer, who also is a partner of OrbiMed Advisors LLC and of OrbiMed Capital GP III LLC, was the recipient of a grant of stock options of the Issuer (the “Director’s Stock Options”).  Pursuant to an agreement with the Reporting Persons, Sheffery is obligated to transfer any Shares issued under the Director’s Stock Options to the Reporting Persons, who will distribute the Shares to Caduceus and Associates on a pro-rata basis.

The amount shown represents (i) options to purchase 74,292 Shares, held by Caduceus, (ii) options to purchase 708 Shares, held by Associates.
 

 
This statement relates to the acquisition of Shares by the Reporting Persons.  The Shares acquired by the Reporting Persons were acquired 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 the Reporting Persons’ respective advisory clients.
 
The Reporting Persons previously were granted and exercised the right to appoint a representative to the Board of Directors (the “Board”) of the Issuer, so as to permit active monitoring of the operations of the Issuer.  As mentioned above, Michael B. Sheffery currently serves as the Reporting Persons’ representative on the Board.
 
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 of Common Stock 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.
 
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 or 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, OrbiMed Advisors LLC, OrbiMed Capital GP III LLC and Samuel D. Isaly may be deemed directly or indirectly, including by reason of their mutual affiliation, to be the beneficial owners of the Shares described in Item 3.  Based upon information contained in the most recent available filing by the Issuer with the SEC, such Shares constitute approximately 12.98% of the issued and outstanding Shares.  As described above in Item 2, Isaly owns, pursuant to the terms of the limited liability company agreement of each of
 

 
OrbiMed Advisors LLC and OrbiMed Capital GP III LLC, a controlling interest in the outstanding limited liability company interests of such entity.  As a result, Isaly, OrbiMed Advisors LLC and OrbiMed Capital GP III LLC share power to direct the vote and to direct the disposition of the Common Stock described in Item 3.
 
(c) Except as disclosed in Item 3, the Reporting Persons have not effected any transactions in the Shares during the past sixty (60) days.
 
(d) Not applicable.
 
(e) Not applicable.
 
Item 6.
Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.
 
In addition to the relationships between the Reporting Persons described in Item 5, OrbiMed Capital GP III LLC is the general partner of Caduceus, pursuant to the terms of its limited partnership agreement. OrbiMed Advisors LLC acts as investment manager of Associates, pursuant to the terms of its investment advisory agreement. Pursuant to these agreements and relationships, OrbiMed Advisors LLC and OrbiMed Capital GP III LLC have discretionary investment management authority with respect to the assets of these investment accounts. Such authority includes the power to vote and otherwise dispose of securities purchased by Caduceus and Associates. The number of outstanding Shares of the Issuer attributable to Caduceus is 1,788,100 Shares and 742,925 Warrants and to Associates 17,000 Shares and 7,075 Warrants. OrbiMed Advisors LLC, pursuant to its authority under its investment advisory contracts with Associates, may be considered to hold indirectly 17,000 Shares and 7,075 Warrants and OrbiMed Capital GP III LLC, pursuant to its authority under its investment advisory contract with Caduceus, may be considered to hold indirectly 1,788,100 Shares and 742,925 Warrants. As noted above under Item 4, Michael B. Sheffery, a partner of OrbiMed Advisors LLC and of OrbiMed Capital GP III LLC, has been appointed to the Board of the Issuer and, accordingly, the Reporting Persons may have the ability to effect and influence control of the Issuer.
 
Also as noted in Item 4, Sheffery has been granted a number of Director’s Stock Options and is obligated to transfer any Shares issued pursuant to such Options to the Reporting Persons, who will distribute the Shares to Caduceus and Associates on a pro-rata basis.  Accordingly, the number of Director’s Stock Options attributable to Caduceus and Associates is 74,292 and 708, respectively.  Of these OrbiMed Advisors LLC and OrbiMed Capital GP III LLC may be considered to hold indirectly 708 and 74,292 Director’s Stock Options, respectively.
 
Other than the agreements and the relationships mentioned above, to the best knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any persons with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any of the Shares, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
