Traws Pharma Inc. announced the completion of enrollment in its Phase 2 clinical study evaluating ratutrelvir, an investigational oral Mpro/3CL protease inhibitor, in comparison to PAXLOVID® in patients with mild-to-moderate COVID-19. The study also includes a single arm for patients ineligible to receive PAXLOVID®. According to the company, ongoing clinical results indicate ratutrelvir has demonstrated a differentiated profile versus PAXLOVID®, with observations of fewer adverse events, absence of viral rebounds, and faster time to sustained symptom resolution. These findings have also been observed in PAXLOVID®-ineligible patients. Final results have not yet been presented. Additionally, Traws Pharma provided an update on its tivoxavir marboxil program, indicating that a new compressed tablet formulation may offer 28-day prophylactic protection against a broad range of seasonal and pandemic-potential influenza variants. A human influenza prophylaxis challenge study is scheduled for June 2026, following a planned bridging study in healthy volunteers to confirm extended drug exposure. Results from the challenge study will determine progression to registration studies.
