Change From Baseline in the Acceptability of Intervention Measure (AIM) Total Score in Staff Study Participants at Month 4
Baseline and Month 4

AIM is a four item survey that assessed the acceptability of an implementation process. The staff study participants were asked to indicate how much they agreed or disagreed with each of the 4 items in the AIM based on their current experiences with implementing the CAB + RPV injection treatment on a five point rating scale (1=completely disagree to 5=completely agree). The AIM total score ranges from 1 to 5 with 1 indicating the least acceptability and 5 the most acceptability. Baseline is defined as the latest pre-treatment assessment with a non-missing value, including those from unscheduled visits. Change from Baseline value is defined as post-dose value minus Baseline value.

CAB trough concentrations for target of 1.05 microgram per milliliter (μg/mL) for men and 1.39 μg/mL for women
From Month 13 to Month 25

CAB trough concentrations are evaluated at or above the target of 1.05 μg/mL for men and 1.39 μg/mL for women, once steady state has been achieved, but no earlier than Month 13 of the study.

Percentage of Participants With HIV-ribonucleic Acid (RNA) >=50 Copies Per Milliliter (c/mL) as Per Food and Drug Administration (FDA) Snapshot Algorithm at Month 12 [Maintenance Phase]
At Month 12 [Maintenance Phase]

Percentage of participants with HIV-1 RNA \>=50 c/mL as per FDA snapshot algorithm at Month 12 was assessed to demonstrate the antiviral activity of CAB LA+RPV LA Q2M and DTG + RPV regimen in HIV-1 infected antiretroviral therapy (ART) experienced participants. The HIV-1 RNA \>=50 c/mL per Snapshot algorithm was determined by the last on-treatment HIV-1 RNA measurement within the 12 months analysis visit window.

ArmTypeDescription
CAB LA + RPV LA GroupEXPERIMENTALParticipants receive initial injections at Day 1 and Month 1, followed by maintenance injections every 2 months for up to 24 months.
Oral ART Control GroupACTIVE_COMPARATORParticipants continue to take their current oral ART for 6 months, including a final dose at their first injection visit.
CAB LA 600 mg (Q8W)EXPERIMENTALAll enrolled participants have previously received CAB LA as part of the HPTN 083 and HPTN 084 parent studies or their sub-studies. Participants will continue receiving CAB LA 600 mg via gluteal intramuscular (IM) injection.
Subjects with HIV infectionEXPERIMENTALHIV-infected subjects receiving CAB LA+RPV LA will be included in this arm.
CAB GroupEXPERIMENTALParticipants receive lead-in injections comprising cabotegravir LA during month one and injections of a new formulation of CAB LA at Month 3, Month 5 and every 4 months thereafter to Month 29.
CAB LA + RPV LA Q2MEXPERIMENTALEligible participants from LAI116482 (NCT01641809 \[LATTE\]) study who were administered oral CAB 30 milligrams (mg) plus RPV 25 mg and who successfully completed Week 300 received their first dose CAB LA (600 mg) plus RPV LA (900 mg) injections within 2 hours of the final oral dose of LATTE given on the same day. The second loading injections were administered 1 month after initial loading dose, with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) occurring Q2M thereafter. Participants continued to receive the treatment until the study intervention was locally approved and commercially available. Participants who received at least one dose of CAB LA and/or RPV LA and discontinued the CAB LA + RPV LA regimen for any reason entered a 52-week long-term follow-up (LTFU) Phase.
DTG + RPVEXPERIMENTALEligible participants from LAI116482 (NCT01641809 \[LATTE\]) study who were administered oral CAB 30 mg plus RPV 25 mg and who successfully completed Week 300 received their first dose of the Dolutegravir (DTG) 50 mg plus RPV 25 mg, once daily as oral regimen on Day 1 until Month 12 in the current study. These participants were not eligible for the LTFU phase.
LTFU: CAB LA+RPV LA Q2M GroupEXPERIMENTALThis group included the participants who received at least one dose of CAB LA and/or RPV LA and discontinued the CAB LA + RPV LA regimen for any reason before end of Maintenance Period. The participants entered a 52-week LTFU period.
