What this trial studies

This Phase 1 interventional study enrolls healthy adult volunteers to measure drug levels when atorvastatin and metformin are given with and without ulonivirine. Participants will receive the study drugs under controlled conditions and have blood samples taken over time to compare concentrations and pharmacokinetics. Safety monitoring including labs and ECGs will be performed during the study period. Results will clarify whether coadministration alters exposure to the commonly used drugs atorvastatin and metformin.

Who should consider this trial

Good fit: Healthy adults with a body mass index between 18.0 and 32.0 kg/m2 who have no significant medical history and test negative for HIV, hepatitis B, and hepatitis C.

Not a fit: People with a history of cancer, positive HIV/HBV/HCV tests, significant medical conditions, or those on chronic medications are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, this could help doctors know whether dose changes are needed when patients take ulonivirine with atorvastatin or metformin.

How similar studies have performed: Drug–drug interaction studies like this have guided dosing for other antiviral and chronic medications, but specific interaction data for ulonivirine with atorvastatin and metformin are limited.
