Phase 2b, Open-label, Multicenter, Rollover Study to Assess Antiviral Activity and Safety of Long-acting (LA) Cabotegravir (CAB) Plus LA Rilpivirine (RPV), Administered Every 2 Months (Q2M), in Human Immunodeficiency Virus (HIV)-Positive Participants From the LATTE Study

Phase 2

Completed

Conditions: HIV Infections

Interventions: Drug: RPV
Drug: CAB LA
Drug: RPV LA
Drug: DTG

Registration Number: NCT03639311

Lead Sponsor: ViiV Healthcare

Brief Summary: This study (POLAR), is designed to assess the antiviral activity and safety of CAB LA plus RPV LA, administered Q2M, in approximately 100 adult HIV-1 infected, antiretroviral therapy (ART) experienced participants. Participants will rollover from the NCT01641809 (LATTE) study, who have completed minimum duration of Week 312 and with demonstrated HIV-1 ribonucleic acid (RNA) suppression (less than \[\<\]50 copies (c) per milliliter \[mL\]), while receiving a two-drug regimen consisting of once-daily oral CAB at 30 milligram (mg) plus RPV at 25 mg. The participants will be offered the option to switch to the LA, intramuscular injections of CAB LA plus RPV LA, Q2M or the oral fixed dose combination (FDC) of dolutegravir (DTG) plus RPV, for the continued maintenance of HIV-1 RNA suppression, known as the Maintenance Phase (From Day 1 to Commercial Approval). Duration of study will vary from country to country, until regimen receives regulatory approval and becomes commercially available. The study plans to enroll approximately 100 participants. Any participant who receives at least one dose of CAB LA and/or RPV LA and discontinues the CAB LA plus RPV LA regimen for any reason will enter a 52-week Long-Term Follow-Up (LTFU) phase. Those participants must remain on suppressive highly active antiretroviral therapy (HAART) for at least 52 weeks after the last dose of CAB LA and or RPV LA.

The Weighted Impact Score (WIS) was calculated for the 26 domain items by multiplying impact score(IS) (-3\[maximum {max.} negative impact\] to +1\[max. positive impact\] by the corresponding importance score (3 \[very important\] to 0\[not all important\]). Average Weighted Impact (AWI) score was calculated by summing individual weighted IS and dividing by the number of domain items. The ranges of WIS and average IS were from -9(max. negative) to +3(max. positive);higher score indicates positive impact. Change from Baseline was defined as post-dose visit value minus Baseline value (latest pre-treatment assessment with a non-missing value). SD=0.00 is defined as SD resulted below the detectable limit of the assay and approximate to 0.00.
