Can this new drug safely reverse a blood thinner? early trial underway
NCT ID NCT07202663
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This early-phase trial tested the safety of a new drug called BB-025, designed to reverse the effects of another experimental drug, BB-031. 72 healthy volunteers received either BB-025 or a placebo, alone or after BB-031, and were monitored for 28 days. The main goal was to check for side effects and measure how the drugs move through the body.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BB-025 (reversal agent) and BB-031 (RNA aptamer)
- What this could lead to
- If successful, this could lead to a way to quickly reverse the effects of BB-031, which might be used as a blood thinner.
- What could go wrong
- This is an early Phase 1 trial in healthy volunteers, not patients. It only tests safety and drug levels, not whether the reversal agent works in a real medical emergency.
