Current/Last Presiding Judge:  
Hon. Charles R. Breyer

Filing Date: June 07, 2024

According to the Complaint, Gritstone bio, Inc., a clinical-stage biotechnology company, engages in developing vaccine-based immunotherapy candidates against cancer and infectious diseases.

In September 2023, Gritstone entered into a contract with the Biomedical Advanced Research and Development Authority to run a 10,000 participant, randomized Phase 2b double-blinded study to compare the efficacy, safety, and immunogenicity of its COVID-19 vaccine candidate with an approved COVID-19 vaccine.

The Complaint alleges that throughout the Class Period, Defendants made materially false and misleading statements regarding the Company's business, operations, and prospects. Specifically, the Complaint alleges Defendants made false and/or misleading statements and/or failed to disclose that: (i) the Company would be unable to launch the Phase 2b CORAL Study in the timeframe it had represented to investors; (ii) the foregoing would impair Gritstone's ability to obtain external funding in connection with the Study, thereby negatively affecting Gritstone's ability to maintain its balance sheet and cash position; (iii) accordingly, Gritstone overstated its ability to successfully develop and commercialize its products; (iv) as a result, the Company's public statements were materially false and misleading at all relevant times.

Plaintiff voluntarily dismissed this case on June 17, 2024. A related case continues under Docket 24-CV-03640.

On September 10, 2024, the Court issued an Order appointing Lead Plaintiff and Counsel. Lead Plaintiff filed an amended Complaint on November 8.
