ATLANTA, Sept. 22, 2025 (GLOBE NEWSWIRE) -- A shareholder class action lawsuit has been filed against Jasper Therapeutics, Inc. (“Jasper” or the “Company”) (NASDAQ: JSPR). The lawsuit alleges that Defendants made materially false and/or misleading statements and/or failed to disclose material adverse information regarding Jasper’s business, operations, and compliance policies, including allegations that: (i) 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; (ii) the foregoing failure increased the risk that results of ongoing studies would be confounded, thereby negatively impacting the regulatory and commercial prospects of the Company’s products, including briquilimab; (iii) the foregoing increased the likelihood of disruptive cost-reduction measures; and (iv) accordingly, Jasper’s business and/or financial prospects, as well as briquilimab’s clinical and/or commercial prospects, were overstated.
