Item 3 is hereby amended and restated to read as follows:

The Shares purchased by BVF, BVF2 and Trading Fund OS were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted. The aggregate purchase price of the 1,265,953 Shares owned directly by BVF is approximately $15,075,269, including brokerage commissions. The aggregate purchase price of the 1,103,314 Shares owned directly by BVF2 is approximately $14,041,998, including brokerage commissions. The aggregate purchase price of the 159,537 Shares owned directly by Trading Fund OS is approximately $1,324,498, including brokerage commissions. The aggregate purchase price of the 231,878 Shares held in the Partners Managed Accounts is approximately $1,005,667, including brokerage commissions.

The aggregate purchase price of the 2,313 shares of Series X Convertible Preferred Stock, par value $0.05 per share (the “Series X Preferred Stock”) owned directly by BVF is approximately $9,321,390, including brokerage commissions. The aggregate purchase price of the 1,506 shares of Series X Preferred Stock owned directly by BVF2 is approximately $6,069,180, including brokerage commissions. The aggregate purchase price of the 412 shares of Series X Preferred Stock owned directly by Trading Fund OS is approximately $1,660,360, including brokerage commissions. The aggregate purchase price of the 772 shares of Series X Preferred Stock held in the Partners Managed Accounts is approximately $3,111,160, including brokerage commissions.

The Shares beneficially owned by Mr. Perry were awarded by the Issuer in connection with his service as a director.

Item 5.

Interest in Securities of the Issuer.

Items 5(a)-(c) are hereby amended and restated to read as follows:

(a)                The aggregate percentage of Shares reported owned by each person named herein is based on a denominator that is the sum of: (i) 9,761,901 Shares outstanding as of March 5, 2020, which is the total number of Shares outstanding as reported in the Issuer’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 10, 2020, (ii) certain or all of the 1,252,772 Shares underlying the Series Y Preferred Stock and (iii) with respect to Mr. Perry, 28,441 Shares issuable on the exercise of certain options.

As of the date hereof, the Reporting Persons hold 5,003 shares of Series X Preferred Stock, convertible into an aggregate of 5,003,000 Shares. Each share of Series X Preferred Stock is convertible into 1,000 Shares. The Series X Preferred Stock may not be converted if, after such conversion, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), more than 19.99% of the Shares outstanding immediately after giving effect to such conversion (the “Series X Beneficial Ownership Limitation”). As of the date hereof, the Series X Beneficial Ownership Limitation, limits the aggregate conversion of the Series X Preferred Stock by the Reporting Persons to zero out of the 5,003,000 Shares underlying the Series X Preferred Stock.

As of the date hereof, the Reporting Persons hold 1,252.772 shares of Series Y Preferred Stock, convertible into an aggregate of 1,252,772 Shares. Each share of Series Y Preferred Stock is convertible into 1,000 Shares based on a conversion price of $13.00 per Share. The Series Y Preferred Stock may not be converted if, after such conversion, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Exchange Act, more than 50.0% of the Shares outstanding immediately after giving effect to such conversion (the “Series Y Beneficial Ownership Limitation”). As of the date hereof, the Series Y Beneficial Ownership Limitation does not limit the aggregate conversion of the Series Y Preferred Stock by the Reporting Persons.

As of the date hereof, (i) BVF beneficially owned 1,921,912 Shares, including 655,959 Shares issuable upon the conversion of certain Series Y Preferred Stock and excluding 2,313,000 Shares issuable upon the conversion of certain Series X Preferred Stock, representing percentage ownership of approximately 18.5% of the Shares outstanding, (ii) BVF2 beneficially owned 1,700,127 Shares, including 596,813 Shares issuable upon the conversion of certain Series Y Preferred Stock and excluding 1,506,000 Shares issuable upon the conversion of certain Series X Preferred Stock, representing percentage ownership of approximately 16.4% of the Shares outstanding, (iii) Trading Fund OS beneficially owned 159,537 Shares, excluding 412,000 Shares issuable upon the conversion of certain Series X Preferred Stock, representing percentage ownership of approximately 1.6% of the Shares outstanding, and (iv) 231,878 Shares were held in the Partners Managed Accounts, excluding 772,000 Shares issuable upon the conversion of certain Series X Preferred Stock, representing percentage ownership of approximately 2.4% of the Shares outstanding.

BVF2 GP, as the general partner of BVF2, may be deemed to beneficially own the 1,700,127 Shares beneficially owned by BVF2, representing percentage ownership of approximately 16.4% of the Shares outstanding.

Partners, as the investment manager of BVF, BVF2, Trading Fund OS and the Partners Managed Accounts and the sole member of Partners OS, may be deemed to beneficially own the 4,013,454 Shares beneficially owned in the aggregate by BVF, BVF2, Trading Fund OS, and held in the Partners Managed Accounts, representing percentage ownership of approximately 36.4% of the Shares outstanding.

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 4,013,454 Shares beneficially owned by Partners, representing percentage ownership of approximately 36.4% of the Shares outstanding.

Mr. Lampert, as a director and officer of BVF Inc. may be deemed to beneficially own the 4,013,454 Shares beneficially owned by BVF Inc., representing percentage ownership of approximately 36.4% of the Shares outstanding.

As of the date hereof, Mr. Perry beneficially owned 40,240 Shares, including 28,441 Shares issuable on the exercise of certain options that are exercisable within sixty days hereof, representing percentage ownership of less than 1%.

(b)       Each of BVF, BVF2 and Trading Fund OS shares with Partners voting and dispositive power over the Shares each such entity beneficially owns. BVF shares with BVF GP voting and dispositive power over the Shares beneficially owned by BVF. BVF2 shares with BVF2 GP voting and dispositive power over the Shares beneficially owned by BVF2. Each of BVF GP and BVF2 GP shares with BVF GPH voting and dispositive power over the Shares each such entity beneficially owns. Trading Fund OS shares with Partners OS voting and dispositive power over the Shares beneficially owned by Trading Fund OS. Partners, BVF Inc. and Mr. Lampert share voting and dispositive power over the 4,005,341 Shares they may be deemed to beneficially own with BVF, BVF GP, BVF2, BVF2 GP, Trading Fund OS, Partners OS, BVF GPH and the Partners Managed Accounts.

(c)       Schedule A annexed hereto lists all transactions in securities of the Issuer by the Reporting Persons since the filing of Amendment No. 3 to the Schedule 13D. All of such transactions were effected in the open market.

The filing of this Schedule 13D shall not be deemed an admission that the Reporting Persons are, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, the beneficial owners of any securities of the Issuer that he or it does not directly own. Each of the Reporting Persons specifically disclaims beneficial ownership of the securities reported herein that he or it does not directly own.
