Can an experimental drug share the Body's chemical highways without causing a pileup?
NCT ID NCT07820891
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers are running a Phase 1 trial to see whether the experimental drug BGB-43395 changes how the body handles four other medicines: midazolam, celecoxib, dabigatran, and rosuvastatin. About 24 healthy adults take BGB-43395 along with these probe drugs in a fixed sequence. The team measures blood levels of the probe drugs to check for drug interactions and tracks side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BGB-43395, an experimental oral drug, given with four probe drugs (midazolam, celecoxib, dabigatran, and rosuvastatin)
- What this could lead to
- If BGB-43395 does not disrupt how the body clears these probe drugs, researchers gain confidence that it may be safer to combine with other medicines later.
- What could go wrong
- This is a small Phase 1 study in healthy volunteers, so it cannot show whether BGB-43395 works for any disease. A drug interaction found here could complicate future use, and healthy participants may still experience side effects.
