New drug candidate B-OT takes first step in human safety trial
NCT ID NCT07450833
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tested the safety and tolerability of an experimental drug called Benfo-Oxythiamine (B-OT) in 48 healthy male volunteers. Researchers gave the drug as single or multiple daily doses and monitored participants closely for side effects, blood levels, and lab changes. The goal was to see if B-OT is safe enough to study further for possible use against infectious diseases and cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Benfo-oxythiamine (B-OT)
- What this could lead to
- If this drug proves safe, it could pave the way for future studies testing B-OT as a treatment for infectious diseases or cancer.
- What could go wrong
- This is a very early Phase 1 trial in only 48 healthy volunteers. It only looks at safety and how the drug moves through the body, not whether it works against any disease. Many drugs fail in later stages.
