The Allegations: Robbins LLP is Investigating Allegations that Gritstone bio, Inc. (GRTS) Misled Investors Regarding the Initiation of its Phase 2b CORAL Study

According to the complaint, in September 2023, Gritstone entered into a contract with the Biomedical Advanced Research and Development Authority (“BARDA”) 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 (a samRNA vaccine candidate) with an approved COVID-19 vaccine (the “Phase 2b CORAL Study” or the “Study”). In a press release announcing the Study, the Company stated the Study would be fully funded by BARDA and was expected to launch in the first quarter of 2024.

Plaintiff alleges that during the class period, defendants 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; and (iii) accordingly, Gritstone overstated its ability to successfully develop and commercialize its products.

The complaint alleges that on February 12, 2024, Gritstone announced the delay of the launch of the Study until Fall 2024. Then, on February 29, 2024, Gritstone announced an approximate 40% reduction of its workforce "following the recently announced delay of the proposed CORAL Phase 2b study, which resulted in Gritstone not receiving external funding it previously anticipated beginning in 1Q 2024, associated with the initiation of the study. On this news, Gritstone's stock price fell almost 28%, to close at $2.02 per share on March 1, 2024.
