Summary
This is an open-label, dose-escalation study to investigate the safety, tolerability and pharmacokinetics (PK) of single subcutaneous (SC) administration of long acting (LA) Cabotegravir (CAB) 200 milligrams per milliliter (mg/mL) with Recombinant Human Hyaluronidase PH20 (rHuPH20) (Part A), a single-dose or repeat-dose SC or intramuscular (IM) administration of LA CAB (greater than or equal to) \>=400 mg/mL (Part C), single-dose IM administration of LA CAB Formulation I (Part C Cohort C8) and LA CAB Formulation J (Part C Cohort C11), and a single-dose or repeat-dose IM administration of rilpivirine (RPV) (Part E). Part A of the study (CAB 200 mg/mL with rHuPh20) has been closed to further enrolment based on preliminary results. Part D of the study (CAB \>=400 mg/mL with rHuPH20) will not be conducted due to changes in the study design.
