Case details:

According to the complaint, Gritstone is a clinical-stage biotechnology company that is developing potential vaccine-based immunotherapies for cancer and infectious diseases.

According to the complaint, in September 2023, Gritstone entered into an agreement with the Biomedical Advanced Research and Development Authority (“BARDA”) to conduct a 10,000-participant, randomized, double-blind Phase 2b study to compare the efficacy, safety and immunogenicity of its drug candidate COVID-19 vaccine (samRNA vaccine candidate) with an approved COVID-19 vaccine (the “Phase 2b CORAL Study” or the “Study”). In a press release announcing the Phase 2b CORAL study, the Company stated that the contract “provides strong validation of (its) innovative infectious disease vaccine platform”, that execution of the study will be fully funded by BARDA, and that the study is expected to launch in the first quarter of 2024 year.

The complaint alleges that throughout the term of the agreement, Gritstone made false and misleading statements regarding the Company’s business, operations and prospects. Specifically, Gritstone made false and/or misleading statements and/or failed to disclose that:

(1) the Company will not be able to commence the Phase 2b CORAL Study on the date it has presented to investors;

(2) the foregoing would hamper Gritstone’s ability to obtain external financing in connection with the Study, thereby adversely affecting Gritstone’s ability to maintain its balance sheet and cash position;

(3) therefore, Gritstone overestimated its ability to successfully develop and commercialize its products; AND

(4) as a result, the Company’s public statements were materially false and misleading at all material times.

According to the complaint, the truth began to emerge on February 12, 2024, when Gritstone issued a press release announcing that the Company was delaying the initiation of the Study until the fall of 2024 to allegedly “enable the use of fully compliant raw materials in production.” with GMP. vaccine, which is expected to increase the regulatory utility of the study.” Gritstone then issued a press release on February 29, 2024 in which it “announces (announces) a reduction in its workforce of approximately 40%,” stating that “this move comes in conjunction with the recently announced delay of the proposed Phase 2b CORAL trial, which has resulted in Gritstone has not received previously anticipated external financing beginning in Q1 2024 related to the initiation of the study.”

On this news, the Gritstone share price fell by $0.78 per share, or 27.86%, to close at $2.02 per share on March 1, 2024.

Therefore, the complaint alleges that as a result of Gritstone’s unlawful acts and omissions and the sharp decline in the market value of the Company’s securities, investors have suffered significant losses and damages.
