Brief 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.

Primary Outcome Measures :
  1. Assessment of Plasma CAB Pharmacokinetic (PK) Parameter: Area Under the Concentration-time Curve Over One Dosing Interval (AUC [0 to Tau]) [ Time Frame: Pre-dose (within 15 minutes prior to dose) on Days 13 and 14; and 1, 2, 3, 4, 8, 12, and 24 hours post-dose on Day 14, pre-dose (within 15 minutes prior to dose) on Days 26, 27 and 28; and 1, 2, 3, 4, 8, 12 and 24 hours post-dose on Day 28 ]
    Blood samples for PK analysis of CAB were collected at pre-dose (within 15 minutes prior to dose) on Days 13 and 14; and 1, 2, 3, 4, 8, 12, and 24 hours post-dose on Day 14, pre-dose (within 15 minutes prior to dose) on Days 26, 27 and 28; and 1, 2, 3, 4, 8, 12 and 24 hours post-dose on Day 28. AUC (0 to tau) was calculated using the linear trapezoidal rule for each incremental trapezoid and the log trapezoidal rule for each decremental trapezoid. PK Summary Population included participants who had CAB PK parameter estimates from both serial PK sampling time periods 1 and 2.
