Details of the case:

According to the lawsuit, throughout the Class Period, defendants made false and/or misleading statements and/or failed to disclose that:

  • Gritstone would be unable to launch the Phase 2b CORAL Study, a study comparing Gritstone’s COVID-19 vaccine candidate with an approved COVID-19 vaccine, in the timeframe it had represented to investors;
  • the foregoing would impair Gritstone’s ability to obtain external funding in connection with the Phase 2b CORAL Study, thereby negatively affecting Gritstone’s ability to maintain its balance sheet and cash position;
  • accordingly, Gritstone overstated its ability to successfully develop and commercialize its products; and
  • as a result, Gritstone’s public statements were materially false and misleading at all relevant times.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
