The disclosure in Item 4 below is incorporated herein by reference. The securities of the Issuer purchased by the Funds (as defined below) reported herein were purchased with working capital both in open market transactions directly with a broker dealer and in private transactions directly with the Issuer. The aggregate purchase price of the securities of the Issuer directly held by the Funds reported herein was approximately $127,111,191.

 

 

 

 

Item 4. Purpose of the Transaction.

 

667, L.P. (“667”) and Baker Brothers Life Sciences, L.P. (“Life Sciences”, and together with 667, the “Funds”) hold securities of the Issuer previously purchased in private transactions directly with the Issuer and previously purchased in open market transactions directly with a broker dealer. All securities were purchased using the working capital of the Funds. Julian C. Baker and Felix J. Baker each directly hold 23,459 shares of Common Stock of the Issuer received as part of a pro-rata distribution from 14159, L.P. for no consideration on January 28, 2015. On September 23, 2015, Stephen R. Biggar, an employee of the Adviser and former director of the Issuer, exercised options to purchase 5,833 shares of Common Stock of the Issuer that were granted to Mr. Biggar during his previous service on the Board of Directors of the Issuer (the “Board”). Mr. Biggar previously served on the Board as a representative of the Funds. The policy of the Funds and the Adviser does not permit employees of the Adviser to receive compensation for serving as a Director of the Issuer. Therefore, Mr. Biggar has no pecuniary interest in any options to purchase Common Stock or shares of Common Stock directly held by him. The Funds are instead entitled to the pecuniary interest in any options to purchase Common Stock and shares of Common Stock received as director compensation. As of the date of the filing of this Schedule 13D, Mr. Bigger also directly holds options to purchase 90,000 shares of Common Stock of the Issuer that were granted to him during his service on the Board.

 

The information in Item 5(c) is incorporated by reference herein.

 

The Funds hold securities of the Issuer for investment purposes. The Reporting Persons or their affiliates may purchase additional securities or dispose of securities in varying amounts and at varying times depending upon the Reporting Persons’ continuing assessments of pertinent factors, including the availability of shares of Common Stock or other securities for purchase at particular price levels, the business prospects of the Issuer, other business investment opportunities, economic conditions, stock market conditions, money market conditions, the attitudes and actions of the board of directors and management of the Issuer, the availability and nature of opportunities to dispose of shares of the Issuer and other plans and requirements of the particular entities. The Reporting Persons may discuss items of mutual interest with the Issuer, which could include items in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

 

Depending upon their assessments of the above factors, the Reporting Persons or their affiliates may change their present intentions as stated above and they may assess whether to make suggestions to the management of the Issuer regarding financing, and whether to acquire additional securities of the Issuer, including shares of Common Stock (by means of open market purchases, privately negotiated purchases, or otherwise) or to dispose of some or all of the securities of the Issuer, including shares of Common Stock, under their control.

 

Except as otherwise disclosed herein, at the present time, the Reporting Persons do not have any plans or proposals with respect to any extraordinary corporate transaction involving the Issuer including, without limitation, those matters described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

 

Item 5.   Interest in Securities of the Issuer.

 

(a) and (b) Items 7 through 11 and 13 of each of the cover pages of this Schedule 13D are incorporated herein by reference.
