Item 1. | Security and Issuer |
Item 1 of the Statement is amended and supplemented as follows:
This Amendment No. 11 (this “Amendment No. 11” or this “13D/A”) amends and supplements the Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on November 13, 2019, and amended on July 10, 2020, September 21, 2020, June 2, 2021, July 6, 2022, October 21, 2022, March 30, 2023, August 11, 2023, December 13, 2023, March 6, 2024 and August 7, 2024 (as amended, the “Statement”), filed by RA Capital Management, L.P., Dr. Kolchinsky, Mr. Shah, and RA Capital Healthcare Fund, L.P. with respect to the common stock, par value $0.001 per share (the “Common Stock”), of 89bio, Inc., a Delaware corporation (the “Issuer”). Unless otherwise defined herein, capitalized terms used in this Amendment No. 11 shall have the meanings ascribed to them in the Statement. Unless amended or supplemented below, the information in the Statement remains unchanged.
Item 2. | Identity and Background |
Item 2 of the Statement is amended and restated in its entirety to read as follows:
(a) | This Amendment No. 11 is being filed on behalf of RA Capital Management, L.P. (“RA Capital”), Peter Kolchinsky, Rajeev Shah, and RA Capital Healthcare Fund, L.P. (the “Fund”), who are collectively referred to herein as the “Reporting Persons.” The agreement among the Reporting Persons to file this 13D/A jointly in accordance with Rule 13d-1(k) of the Securities Exchange Act of 1934, as amended (the “Act”), is attached hereto as Exhibit 1. |
The Reporting Persons’ ownership of the Issuer’s securities includes (i) 13,840,034 shares of Common Stock held directly by the Fund; (ii) 335,364 shares of Common Stock held directly by RA Capital Nexus Fund, L.P. (the “Nexus Fund”); (iii) a total of 78,900 vested stock options (right to buy) held by Derek DiRocco for the benefit of RA Capital; and (iv) a total of 4,331,081 pre-funded warrants (“PFWs”), through which the Fund has the right to acquire 4,331,081 shares of Common Stock subject to the PFW Beneficial Ownership Blocker as defined below. The PFWs contain a provision (the “PFW Beneficial Ownership Blocker”) which precludes exercise of the PFWs to the extent that, following the exercise, the Reporting Persons, together with their affiliates and other attribution parties, would beneficially own more than 9.99% of the Issuer’s outstanding Common Stock. By virtue of the PFW Beneficial Ownership Blocker, the PFWs are currently not exercisable.
RA Capital Healthcare Fund GP, LLC is the general partner of the Fund and RA Capital Nexus Fund GP, LLC is the general partner of the Nexus Fund. The general partner of RA Capital is RA Capital Management GP, LLC, of which Dr. Kolchinsky and Mr. Shah are the controlling persons. RA Capital serves as investment adviser for the Fund and the Nexus Fund and may be deemed a beneficial owner, for purposes of Section 13(d) of the Act, of any securities of the Issuer held by the Fund or the Nexus Fund. The Fund and the Nexus Fund have delegated to RA Capital the sole power to vote and the sole power to dispose of all securities held in the Fund’s and the Nexus Fund’s portfolio, including the shares of the Issuer’s Common Stock reported herein. Because the Fund and the Nexus Fund have divested themselves of voting and investment power over the reported securities they hold and may not revoke that delegation on less than 61 days’ notice, the Fund and the Nexus Fund disclaim beneficial ownership of the securities they hold for purposes of Section 13(d) of the Act and therefore disclaim any obligation to report ownership of the reported securities under Section 13(d) of the Act. As managers of RA Capital, Dr. Kolchinsky and Mr. Shah may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Issuer beneficially owned by RA Capital. RA Capital, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of the securities reported in this 13D/A other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of this 13D/A shall not be deemed an admission that either RA Capital, Dr. Kolchinsky, or Mr. Shah is the beneficial owner of such securities for any other purpose.
(b) | The address of the principal business office of each of the Reporting Persons is 200 Berkeley Street, 18th Floor, Boston, MA 02116. |
(c) | The Fund is a private investment vehicle. RA Capital provides investment management services to the Fund and the Nexus Fund. The principal occupation of each of Dr. Kolchinsky and Mr. Shah is investment management. |
(d) | During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). |
(e) | During the last five years, none of the Reporting Persons has been 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 of 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. |
(f) | See Item 6 of the cover pages. |
Item 3. | Source and Amount of Funds or Other Consideration |
Item 3 of the Statement is hereby amended and supplemented as follows:
2024 Pre-Funded Warrants
On November 14, 2024, the Fund purchased pre-funded warrants (the “2024 Pre-Funded Warrants”) to purchase 3,250,000 shares of Common Stock at a price of $8.499 per warrant share, from the underwriters of the Issuer’s underwritten offering (the “2024 Offering”). The aggregate purchase price for all securities acquired by the Fund in the 2024 Offering was $27,621,750, which was funded by the working capital of the Fund.
Item 5. | Interest in Securities of the Issuer |
Item 5 of the Statement is hereby amended and restated in its entirety to read as follows:
(a) | The information set forth in rows 11 and 13 of the cover pages to this Schedule 13D/A is incorporated by reference. The percentage set forth in row 13 is based on the sum of (i) 117,582,220 shares of Common Stock outstanding as of November 18, 2024, as reported in the Issuer's prospectus supplement dated November 12, 2024 filed with the Securities and Exchange Commission on November 13, 2024, after giving effect to an additional 2,205,882 shares issued and sold pursuant to the underwriters' option; and (ii) 78,900 shares of Common Stock issuable upon exercise of stock options, as applicable. |
(b) | The information set forth in rows 7 through 10 of the cover pages to this Schedule 13D/A and Item 2 above is incorporated by reference. |
(c) | Except as described herein, the Reporting Persons have not effected any transactions in the Common Stock during the past sixty days. |
(d) | No person (other than the Reporting Persons) is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock subject to this 13D/A. |
(e) | Not applicable. |
Item 6. | Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer |
Item 6 of the Statement is hereby amended and supplemented as follows:
Item 3 is incorporated by reference.
2024 Pre-Funded Warrants
Each 2024 Pre-Funded Warrant has an exercise price of $0.001 per share of Common Stock, is immediately exercisable and does not expire. Under the terms of the 2024 Pre-Funded Warrants, the Issuer may not effect the exercise of any 2024 Pre-Funded Warrant, and the Fund will not be entitled to exercise any portion of any 2024 Pre-Funded Warrant, which, upon giving effect to such exercise, would cause the Fund (together with its affiliates) to own more than 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the 2024 Pre-Funded Warrants.
The exercise price and the number of shares of Common Stock issuable upon exercise of each 2024 Pre-Funded Warrant are subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock.
In the event of certain fundamental transactions (as described in the 2024 Pre-Funded Warrants), a holder of 2024 Pre-Funded Warrants will be entitled to receive, upon exercise of the 2024 Pre-Funded Warrants, the kind and amount of securities, cash or property that such holder would have received had they exercised in full the 2024 Pre-Funded Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the 2024 Pre-Funded Warrants.
References to and the description of the 2024 Pre-Funded Warrants set forth above in this Item 6 do not purport to be complete and are qualified in their entirety by reference to the full text of the Form of 2024 Pre-Funded Warrant, which is attached hereto as Exhibit 4 and incorporated by reference herein.
Item 7. | Material to be Filed as Exhibits |
Item 7 of the Statement is amended and supplemented by the following:
Exhibit 1 | Joint Filing Agreement |
