The Allegations: Robbins LLP is Investigating Allegations that Jasper Therapeutics, Inc. (JSPR) Misled Investors Regarding the Commercial Prospects of its Lead Product Candidate Briquilimab

According to the complaint, defendants failed to disclose 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, the Company's business and/or financial prospects, as well as briquilimab's clinical and/or commercial prospects, were overstated.

When the truth was revealed on July 7, 2025, Jasper's stock price fell $3.73 per share, or 55.1%, to close at $3.04 per share on July 7, 2025.
