Investor Alert: Pomerantz Law Firm's Investigation into Summit Therapeutics

Pomerantz LLP, a leading law firm based in New York, is currently investigating claims on behalf of investors who have purchased shares of Summit Therapeutics Inc. (NASDAQ: SMMT). This investigation is primarily focused on whether the company and its executives may have engaged in fraudulent practices regarding securities that could have adversely affected investors' interests.

In a troubling turn of events, the investigation was prompted by a significant announcement made by Summit on May 30, 2025. The company released topline results from the Phase III clinical trial for its drug Ivonescimab, which is aimed at treating serious medical conditions. Although the trial indicated that patients receiving ivonescimab in conjunction with chemotherapy had a lower probability of disease progression or death by 48% compared to those on chemotherapy alone, it failed to demonstrate a statistically significant improvement in overall survival—a crucial measure in evaluating the efficacy of cancer treatments.

Stock Price Impact

As a direct consequence of this announcement, Summit's stock suffered a staggering drop of $7.99 per share, equating to a decrease of 30.5%, closing at approximately $18.22 on the same day. Investors were understandably shaken, leading to increasing scrutiny and questions about the company's practices and transparency.

Just a few months later, on September 7, Summit disclosed additional data from the aforementioned clinical trial, revealing that the outcomes were significantly weaker in North American and European patients compared to those from other regions. In light of this information, the company's stock price plummeted again—this time by $6.54 per share or 25.15%—closing at $19.45 on September 8, 2025.
