Summit Therapeutics Provides Update on Ridinilazole

Menlo Park, CA, July 14, 2022 (GLOBE NEWSWIRE) -- Summit Therapeutics Inc. (NASDAQ: SMMT) (“Summit,” "we," or the “Company”) today provided an update with respect to the clinical development of ridinilazole, its lead Phase III product candidate for the treatment of patients with Clostridioides difficile infection (“C. diff. infection” or “CDI”).

This week, Summit and the US Food & Drug Administration (the “FDA”) held a Type C meeting during which Summit discussed certain data from the Ri-CoDIFy Phase III clinical trial with the agency. The FDA and Summit discussed a possible pathway in which to advance ridinilazole forward with the goal of achieving marketing authorization. This pathway would involve reasonable efforts that would likely involve at least one additional clinical trial. We plan to explore this possibility.

We also plan to share the results from our Ri-CoDIFy Phase III clinical trial through an oral abstract presentation at IDWeek 2022, a major medical conference scheduled to be held in Washington, DC in October. IDWeek is the joint annual meeting of the Infectious Diseases Society of America (IDSA), Society for Healthcare Epidemiology of America (SHEA), the HIV Medicine Association (HIVMA), the Pediatric Infectious Diseases Society (PIDS), and the Society of Infectious Diseases Pharmacists (SIDP).

About the Ri-CoDIFy Study
The Ri-CoDIFy Phase III trial, combining Ri-CoDIFy 1 (NCT: 03595553) and Ri-CoDIFy 2 (NCT: 03595566), is a multi-center, international, double-blinded active-controlled randomized clinical trial comparing ridinilazole, an investigative drug, against vancomycin that randomized 759 patients with C. diff. infection. Patients were randomized 1:1 to receive either ridinilazole or vancomycin. Ridinilazole was administered twice daily for ten days; vancomycin was administered four times daily for ten days. Patients receiving ridinilazole were provided with two placebo pills per day to maintain consistency of administration between the two arms. For inclusion within the study, each patient was required to have a positive C. difficile free toxin test and require antimicrobial treatment for CDI.

The Ri-CoDIFy Phase III study was funded in part with federal funds from the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services, under contract number HHSO100201700014C.
