Summary

This is a Phase I, single-center, open-label, fixed-sequence, 2-period crossover study in healthy adults to evaluate the effect of oral rifabutin (RBT) 300 milligram (mg) on the pharmacokinetics of oral cabotegravir (CAB) 30 milligram ( mg). This study will evaluate the drug-drug interaction (DDI) potential between CAB and RBT to inform dosing strategies for tuberculosis in subjects receiving CAB for human immunodeficiency virus (HIV) treatment or prevention. In Treatment Period 1 (Treatment A) participants will receive CAB 30 mg once daily for 14 days, followed by Treatment Period 2 (Treatment B) where participants will receive RBT 300 mg once daily with CAB 30 mg once daily for 14 days. The total study duration will be approximately for 10 weeks. Approximately 15 healthy subjects will be enrolled to ensure that 12 subjects complete dosing and critical assessments.
