Item 7.01 Regulation FD Disclosure.

On October 11, 2021, Gossamer Bio, Inc. (the “Company”) issued a press release reporting the addition of two CNS-penetrant Bruton's tyrosine kinase, or BTK, inhibitors to its product candidate pipeline discussed in Item 8.01 below. The full text of the press release is attached as Exhibit 99.1 to this Current Report.

The information contained in this Item 7.01, including in Exhibit 99.1 hereto, is being “furnished” and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, is not subject to the liabilities of that section and is not deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except as shall be expressly set forth by specific reference in such a filing.

Item 8.01 Other Events.

On October 11, 2021, the Company announced the addition of two CNS-penetrant BTK inhibitors to its product candidate pipeline. The Company plans to initiate first-in-human studies of the first of these candidates, GB5121, in the fourth quarter of 2021. The Company intends to develop GB5121 in CNS-oncology indications, including relapsed / refractory primary CNS lymphoma, for which a potentially registrational Phase 1b / 2 study is expected to initiate in the first half of 2022. The second product candidate, GB7208, is currently in IND-enabling studies and is expected to enter the clinic in the second half of 2022. The Company intends to develop GB7208 in neuroinflammatory and neurodegenerative diseases, including multiple sclerosis (MS). In a BTK-dependent pre-clinical disease model, GB7208 demonstrated superior outcomes vs. tolebrutinib, a BTK inhibitor being studied in a broad Phase 3 program for MS.
