NCT ID NCT06212336

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This large clinical trial in West Africa is testing several drugs—including favipiravir, ribavirin, dexamethasone, and a new drug called ARN-75039—to find a better treatment for Lassa fever, a viral disease that kills thousands each year. The study will enroll about 1,755 hospitalized patients and measure whether these drugs reduce death and organ failure compared to standard care. The goal is to find a safer and more effective option than the current treatment, ribavirin, which has serious side effects.
