Pomerantz Law Firm Initiates Class Action Against Jasper Therapeutics for Securities Violations

Pomerantz Law Firm Initiates Class Action Against Jasper Therapeutics

In a significant move within the realm of biotechnology, Pomerantz LLP has announced the filing of a class action lawsuit against Jasper Therapeutics, Inc. and certain of its executives. The suit, which is being processed in the United States District Court for the Northern District of California, is categorized under the docket number 25-cv-08010. The class action aims to represent all individuals and entities outside of the defendants that acquired Jasper's securities from November 30, 2023, through July 3, 2025, as they seek damages related to alleged violations of federal securities laws.

Overview of Jasper Therapeutics

Jasper Therapeutics focuses on developing therapeutic solutions aimed at combating mast cell-driven diseases, such as Chronic Spontaneous Urticaria (CSU) and allergic asthma. The company's flagship candidate, briquilimab, attempts to inhibit the stem cell factor from activating the CD117 receptor, which is critical to mast cell functionality. Jasper argues that this blockade could potentially lead to improved outcomes for patients suffering from conditions driven by mast cells.

During 2024, the company made strides by securing an oversubscribed financing round, amassing $50 million aimed at bolstering briquilimab's development and extending its operational cash runway throughout the third quarter of 2025.

The Allegations

However, according to the complaint, Jasper's executives misrepresented the company's operational integrity and compliance standards concerning the manufacturing of their drug candidates. The firm allegedly did not possess adequate systems to guarantee that their selected third-party manufacturers adhered to the stringent current Good Manufacturing Practices (cGMP). This shortcoming purportedly increased risks associated with clinical trials, subsequently impacting the overall business and financial health of the company.

As per the claims, these misleading statements significantly inflated Jasper's market appeal and investments while underrepresenting potential imminent pitfalls stemming from compromised manufacturing practices. For instance, a press release from Jasper on July 7, 2025, disclosed issues with a drug lot used in a clinical trial, which resulted in a notable drop of 55.1% in the company's stock price following this revelation.

Clinical Trials and Their Fallout

Jasper had been conducting several clinical trials, including the BEACON Study, aimed at treating CSU. However, revelations regarding complications with a specific drug lot led to a halt in this and other related studies, ultimately affecting their reputation and market strategies. Analysts swiftly reacted, with BMO Capital Markets downgrading the company's stock status and revising price targets downward, reflecting growing skepticism related to Jasper's trajectory.

Legal Consequences

Investors who acquired Jasper securities during the specified class action period have until November 18, 2025, to engage the court for the designation of Lead Plaintiff in the ongoing litigation. Pomerantz LLP, with its renowned reputation in handling class-action securities cases, has a notable history of advocating for victims of corporate malpractice.

Conclusion

This class action signals an escalating trend wherein investors are actively pursuing accountability within biotech firms wherein operational transparency and compliance are critically under scrutiny. As the litigation unfolds, stakeholders will be observing closely how Jasper Therapeutics navigates these allegations as it attempts to recover from the damaging fallout and maintain its commitment to innovative healthcare solutions.
