All other securities were purchased on the open market. The aggregate purchase price of the securities of the Issuer directly held by the Funds reported herein was approximately $80,541,765.
Item 4. Purpose of the Transaction.
The disclosure in Item 3 and in Item 6 below is incorporated herein by reference.
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 (the “Board”) and management of the Issuer, the availability and nature of opportunities to dispose of securities of the Issuer and other plans and requirements of the particular entities. The Reporting Persons may discuss items of mutual interest with the Issuer’s Board, management and other investors, and other items in subparagraphs (a) through (j) of Item 4 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, conversion of Class A Common Stock, Series A Preferred, Series A-1 Preferred, Series A-2 Preferred 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.
The disclosure in Item 4 is incorporated by reference herein.
(a) and (b) Items 7 through 11 and 13 of each of the cover pages of this Schedule 13D are incorporated herein by reference. Set forth below is the aggregate number of shares of Common Stock directly held by each of the Funds, which may be deemed to be indirectly beneficially owned by the Reporting Persons, as well as shares of Common Stock that may be acquired upon conversion of Class A Common Stock, Series A Preferred, Series A-1 Preferred and Series A-2 Preferred (as defined below), subject to the limitations on conversion described below.

The Class A Common Stock is only convertible to the extent that after giving effect or immediately prior to such exercise the holders thereof, their affiliates and any person who are members of a Section 13(d) group with the holders or one of their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 4.99% of the outstanding Common Stock (the “Beneficial Ownership Limitation”). By written notice to the Issuer, the Funds may from time to time increase or decrease the Beneficial Ownership Limitation applicable to that Fund to any percentage not in excess of 19.99%. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Issuer. As a result of this restriction, the number of shares of Common Stock that may be issued upon conversion of the Class A Common Stock by the above holders may change depending upon changes in the outstanding Common Stock. Due to the Beneficial Ownership Limitation, the Funds cannot presently convert any shares of Class A Common Stock.
The Series A Preferred and Series A-1 Preferred are only convertible to the extent that after giving effect or immediately prior to such conversion the holders thereof, their affiliates and any person who are members of a Section 13(d) group with the holders or one of their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 4.99% of the outstanding Common Stock (the “Series A and Series A-1 Beneficial Ownership Limitation”). By written notice to the Issuer, the Funds may from time to time increase or decrease the Series A and Series A-1 Beneficial Ownership Limitation applicable to that Fund to any percentage not in excess of 19.99%. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Issuer. As a result of this restriction, the number of shares of Common Stock that may be issued upon conversion of the Series A Preferred and Series A-1 Preferred by the above holders may change depending upon changes in the outstanding Common Stock. Due to the Series A and Series A-1 Beneficial Ownership Limitation, the Funds cannot presently convert any shares of Series A Preferred or Series A-1 Preferred.
The Series A-2 Preferred is only convertible to the extent that after giving effect or immediately prior to such conversion the holders thereof, their affiliates and any person who are members of a Section 13(d) group with the holders or one of their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 9.99% of the outstanding Common Stock (the “Series A-2 Beneficial Ownership Limitation”). By written notice to the Issuer, the Funds may from time to time increase or decrease the Series A-2 Beneficial Ownership Limitation applicable to that Fund to any percentage not in excess of 19.99%. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Issuer. As a result of this restriction, the number of shares of Common Stock that may be issued upon conversion of the Series A-2 Preferred by the above holders may change depending upon changes in the outstanding Common Stock.
The Adviser GP is the sole general partner of the Adviser. Pursuant to management agreements, as amended, among the Adviser, the Funds, and their respective general partners, the Funds’ respective general partners relinquished to the Adviser all discretion and authority with respect to the investment and voting power of the securities held by the Funds, and thus the Adviser has complete and unlimited discretion and authority with respect to the Funds’ investments and voting power over investments.
(c) The Reporting Persons or their affiliates have not effected any transactions in securities of the Issuer during the past 60 days.
(d) Certain securities of the Issuer are held directly by 667, a limited partnership the sole general partner of which is Baker Biotech Capital, L.P., a limited partnership the sole general partner of which is Baker Biotech Capital (GP), LLC. Julian C. Baker and Felix J. Baker are the managing members of Baker Biotech Capital (GP), LLC.

Julian C. Baker and Felix J. Baker are the managing members of Baker Brothers Life Sciences Capital (GP), LLC.
(e) Not applicable.
Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
Shareholders Agreement Dated February 15, 2019
The Issuer, the Funds, and several other investors are parties to a Shareholders Agreement dated February 15, 2019 (the “Shareholders Agreement”), providing the Funds and other investor signatories to the Shareholders Agreement with certain registration rights.
Pursuant to the Shareholders Agreement, the Funds may, on two occasions, require the Issuer to file a registration statement covering all or any portion of the Funds’ securities of the Issuer in connection with an underwritten offering if the total offering price of the securities to be sold in such underwritten offering (inclusive of any piggyback shares and before deduction of underwriting discounts) is expected to exceed, in the aggregate, $10,000,000. Additionally, pursuant to the Shareholders Agreement, upon such time as the Issuer shall have qualified for the use of Form S-3, the Issuer is required to file a Shelf Registration Statement on Form S-3 providing for the resale of shares as requested by the Funds if they would be deemed affiliates (as such term is defined in Rule 144 under the Securities Act) of the Issuer at the time of such request, and the Issuer must take steps necessary to keep such Shelf Registration Statement effective for so long as the requesting investor signatories remain affiliates of the Issuer. The Funds are also entitled to piggyback registration rights whereby the Funds may require the Issuer to include their securities of the Issuer in any registration statement that the Issuer files to register its securities either for its own account or for the account of others. The Shareholders Agreement contains customary indemnification provisions pertaining to such registration rights and requires that the Issuer bear certain registration and selling expenses incurred in connection with the registrations described above, other than underwriting discounts and selling commissions.
The foregoing description of the Shareholders Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Shareholders Agreement, which is incorporated by reference as Exhibit 99.2, and incorporated herein by reference.
