Pomerantz Law Firm Investigates Claims Against Summit Therapeutics

On June 7, 2025, Pomerantz LLP announced an investigation of claims on behalf of investors in Summit Therapeutics Inc. (NASDAQ: SMMT). The firm is looking into whether Summit, along with its directors and officers, engaged in securities fraud or other unlawful activities that could have harmed investors. This announcement comes in the wake of recent concerning revelations regarding the company’s clinical trials and the resulting impact on its stock price.

Background on Summit Therapeutics

Summit Therapeutics is a biopharmaceutical company primarily focused on developing innovative treatments for infectious diseases and genetic disorders. The company's notable product candidates include ivonescimab, which recently underwent a Phase III clinical trial known as HARMONi. This was the first global Phase III study evaluating the safety and efficacy of ivonescimab in conjunction with standard chemotherapy.

Recent Developments

On May 30, 2025, Summit released the topline results from the HARMONi study, which indicated that patients receiving ivonescimab alongside chemotherapy were 48% less likely to experience disease progression or death compared to those who received conventional chemotherapy alone. However, despite these findings, the company fell short in demonstrating a statistically significant improvement in overall survival rates, a key metric in clinical trials that measures the duration of life before death from any cause.

As a direct consequence of this news, Summit's stock price plummeted by $7.99, representing a staggering 30.5% drop, closing at $18.22 per share on the same day. Such a drastic decline has raised concerns among investors and led to the initiation of Pomerantz LLP’s investigation.
