Cabotegravir is being developed for the treatment of human immunodeficiency virus (HIV) 1 infection. Specifically, it is being developed as a component of a 2-drug maintenance regimen (post-induction of viral suppression) that includes rilpivirine. Rilpivirine requires food for optimal absorption; therefore the recommended intake of cabotegravir in the planned Phase 3 treatment studies is with food regardless of fat or calorie content, when administered along with rilpivirine. This is a single-center, randomized, open-label, two-way crossover study in healthy adult subjects to assess the effect of a high fat meal on the single dose pharmacokinetics of CAB 30 mg. Approximately, 24 subjects will be enrolled in the study and will be screened for 30 days. Twelve subjects with at least 10 hours of fasting will be randomized to receive a single dose of cabotegravir orally (Schedule 'A'). The remaining 12 subjects will receive a single dose of cabotegravir orally along with high fat meal (Schedule 'B'). After 15 days, the subjects earlier undergoing 'Schedule A' will be switched to 'Schedule B' and those undergoing 'Schedule B' will undergo 'Schedule A'. All the subjects will be followed up to 30 days from the day of receiving first dose of cabotegravir to evaluate the effect of a high fat meal on the pharmacokinetics of cabotegravir.

| Number of subjects with abnormal vital signs (body temperature, systolic and diastolic blood pressure, and pulse rate) | Vital signs will be measured in semi supine position after 10 minutes rest and will include temperature, systolic and diastolic blood pressure and pulse rate. Measurements that deviate substantially from previous readings will be repeated immediately. Two blood pressure (BP) and heart rate (HR) measurements will be taken at pre dose on Day 1.
