Can a new pill tame fungal infections when standard drugs fail?
NCT ID NCT07804368
First seen Sep 04, 2026 · Last updated Sep 04, 2026
Summary
This Phase 2 trial tests an oral antifungal drug called oteseconazole in adults with dimorphic fungal infections, including coccidioidomycosis, blastomycosis, and histoplasmosis. Participants must already be on antifungal therapy but need a different option because standard first-line treatment is not working, causes side effects, or is unavailable. Researchers will track symptoms, daily function, safety, and quality of life during treatment and for up to 6 months after. The goal is to see if oteseconazole can safely control these infections as a salvage or consolidation therapy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oteseconazole (also known as VIVJOA), an oral antifungal drug
- What this could lead to
- If it works, oteseconazole could offer a new treatment option for people with serious fungal infections who cannot tolerate or do not respond to standard antifungal drugs.
- What could go wrong
- This is an early-stage trial with only 30 participants, so results may not apply to everyone. The drug may cause side effects or may not control the infection better than existing options.
