Can VC005 mix safely with common drugs? a trial puts it to the test
NCT ID NCT07796191
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This Phase 1 trial in healthy adults examines whether the investigational drug VC005 interacts with three other medications: verapamil, probenecid, and metformin. Researchers will give participants a single dose of VC005 alone, then combine it with each other drug, measuring how the levels of these drugs change in the blood. The goal is to understand whether VC005 affects or is affected by these common medicines, which helps guide safe dosing in future studies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VC005 tablets, given alone or with verapamil, probenecid, or metformin
- What this could lead to
- If the trial succeeds, it could clarify how VC005 behaves when taken with common medications, helping doctors choose safe doses for future patients.
- What could go wrong
- This is an early-stage trial in healthy volunteers, so results may not predict effects in patients. Drug interactions can vary widely among individuals, and unexpected side effects are possible.
