| Item 1. | Security and Issuer |
Item 1 of the Statement is amended and supplemented as follows:
This Amendment No. 7 (this “Amendment No. 7” or this “13D/A”) amends and supplements the statement on 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, and March 30, 2023 (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. 4 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 13D/A 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 include (1) 11,081,584 Common Stock shares held directly by the Fund, (2) a total of 48,722 vested stock options (right to buy), (3) 694 stock options (right to buy) which shall vest within 60 days of this filing, (4) a total of 2,816,900 warrants (“Warrants”), with each Warrant exercisable for one-half a share of Common Stock, through which the Fund has a right to acquire 1,408,450 Common Stock shares subject to a Beneficial Ownership Blocker detailed below, and (5) 335,364 Common Stock shares held directly by RA Capital Nexus Fund, L.P. (the “Nexus Fund”). The Warrants contain a provision (the “Beneficial Ownership Blocker”) which precludes exercise of the warrants to the extent that, following exercise, the Reporting Persons, together with their affiliates and other attribution parties, would beneficially own more than 19.99% of the Ordinary Shares outstanding. 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 \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 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.

| (a) | The information set forth in rows 11 and 13 of the cover pages to this 13D/A is incorporated by reference. The percentage set forth in row 13 is based on 75,480,884 outstanding shares of Common Stock, as reported by the Issuer in its Form 10-Q filed with the SEC on August 9, 2023. |
| (b) | The information set forth in rows 7 through 10 of the cover pages to this 13D/A and Item 2 above is incorporated by reference. |

|
Item 7 of the Statement is amended and supplemented by the following:
Exhibit 1 Joint Filing Agreement | |
5 The Common Stock and percentage ownership reported in this amendment reflect an increase in the number of outstanding shares of the Issuer. The vesting options in Item 5(c) did not cause a material change in the Reporting Persons’ beneficial ownership.
