Pomerantz Law Firm Investigates Investor Claims on Summit Therapeutics Inc.

Pomerantz LLP has recently initiated an investigation aimed at representing investors of Summit Therapeutics Inc. (NASDAQ: SMMT). This inquiry follows concerning developments linked to the company’s Phase III clinical trial results for the treatment ivonescimab, which resulted in a significant decline in stock price following the announcement.

Recent Developments and Investigation Details

On May 30, 2025, Summit released a press statement detailing the topline findings from the HARMONi clinical trial—its first global Phase III study of ivonescimab combined with chemotherapy. Although the trial reported that patients treated with ivonescimab experienced a 48% lower likelihood of disease progression or death compared to those receiving only chemotherapy, the overall survival rates did not show a statistically significant improvement, a crucial measure for evaluating treatment success. Upon this release, Summit's stock plummeted by 30.5%, closing at $18.22 per share, translating into a loss of $7.99 per share in a single trading day.

The Pomerantz law firm’s inquiry seeks to ascertain if Summit and its executives engaged in any fraudulent activities or unlawful business conduct. Such concerns have spurred discussions among investors, prompting Pomerantz to urge affected parties to reach out to their representatives if they are interested in joining a class action lawsuit.
