Case Details

The Complaint alleges that, throughout the Class Period, Defendants made materially false and misleading statements and/or failed to disclose that: (1) Jasper lacked the controls and procedures necessary to ensure that the third-party manufacturers on which it relied were manufacturing products in full accordance with cGMP regulations and otherwise suitable for use in clinical trials; (2) the foregoing failure increased the risk that results of ongoing studies would be confounded, thereby negatively impacting the regulatory and commercial prospects of Jasper’s products, including briquilimab; (3) the foregoing increased the likelihood of disruptive cost-reduction measures; (4) accordingly, Jasper’s business and/or financial prospects, as well as briquilimab’s clinical and/or commercial prospects, were overstated; and (5) as a result, Defendants’ statements about the Company’s business, operations, and prospects were materially false and misleading at all relevant times.
