Block & Leviton LLP (, a national securities litigation firm, announces that it has filed a class action lawsuit on behalf of shareholders against Gossamer Bio, Inc. (Nasdaq: GOSS) and certain of its officers and directors for securities fraud. The lead plaintiff deadline is June 2, 2020. Investors who purchased Gossamer shares between February 8, 2019 and December 13, 2019, should contact the firm for a free case evaluation.

Gossamer is a clinical-stage biopharmaceutical company focused on developing and commercializing therapeutics in the areas of immunology, inflammation, and oncology. The company’s most advanced product is its GB001 drug, a DP2 antagonist, in development to treat asthma. In February 2019, Gossamer held its initial public offering (“IPO”) of common stock, selling approximately 19.8 million shares at $16.00 each.

The complaint, filed in the U.S. District Court for the Southern District of California, alleges that the materials supporting this offering, and certain of Gossamer’s post-IPO public filings, may have misled investors or otherwise omitted material facts relevant to Gossamer’s GB001 drug and its related clinical trials and studies. The case is captioned Kuhne v. Gossamer Bio, Inc., et al., No. ______ (S.D. Cal.), and was filed at the James M. Carter & Judith N. Keep United States Courthouse, 333 West Broadway, San Diego, California, 92101.

On December 16, 2019, Novartis announced that it was terminating the development of its DP2 antagonist for asthma after it failed a pair of phase 3 clinical trials. As a result, Gossamer’s common stock dropped by approximately 37% in one day. The stock has continued to plummet, and is presently trading around $10.00 per share.
