Study Endpoints

Primary Endpoints

Percentage of Participants With Plasma Human Immunodeficiency Viruses (HIV)-1 Ribonucleic Acid (RNA) Greater Than or Equal to (>=) 50 Copies Per Milliliter (c/mL) at Month 12/11 - ITT-E Population
At month 12/11

Percentage of participants with plasma HIV 1 RNA \>= 50 c/mL at month 12 was assessed using the food and drug administration (FDA) snapshot algorithm. For the Q2M arm, data from the Q2M OLI participants at Month 12 visit and Q2M D2I participants at Month 11 visit were combined as the study objective was to demonstrate the non-inferior antiviral activity of (Q2M) (OLI+ D2I combined) compared to BIK. For BIK arm, data was collected at month 12 visit. Month 12/11 refers to the Month 12 (OLI and BIK) visit/Month 11 (DTI) visit. The FDA snapshot algorithm defines a participant's virologic response status using only the viral load at the predefined time point within a window of time (HIV-RNA equal to or above 50 copies/mL and HIV-RNA below 50 copies/mL), along with study drug discontinuation status. The third category of the FDA snapshot ("No virologic data") is not pre-defined as an endpoint and therefore not reported separately.

The third category of the FDA snapshot ("No virologic data") is not pre-defined as an endpoint and therefore not reported separately.

Percentage of Participants With Plasma Human Immunodeficiency Virus-ribonucleic Acid (HIV-RNA) >=50 Copies Per Milliliter (c/mL) as Per Food and Drug Administration (FDA) Snapshot Algorithm at Week 48
Week 48

Percentage of participants with HIV-1 RNA \>=50 c/mL as per FDA snapshot algorithm at Week 48 was assessed to demonstrate the non-inferior antiviral activity of CAB LA+RPV LA Q8W compared to CAB LA + RPV LA Q4W regimen over 48 weeks in HIV-1 infected 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 Week 48 analysis visit window. Intent-to-treat-Exposed (ITT-E) Population comprised of all randomized participants who received at least one dose of study treatment. Participants were assessed according to their randomized treatment, regardless of the treatment they received.

Week 48

Number of participants with virologic failure endpoint (HIV-1 RNA\>=50 c/mL) as per Food and Drug Administration (FDA) snapshot algorithm at Week 48 was assessed to demonstrate the non-inferior antiviral activity of switching to intramuscular (IM) CAB LA+RPV LA every 4 weeks compared to continuation of current ART regimen over 48 weeks in HIV-1 infected ART-experienced participants. The HIV-1 RNA \>=50 copies/mL per snapshot algorithm was determined by the last available on-treatment HIV-1 RNA measurement within the analysis visit window of interest.

Percentage of Participants With Virologic Failure (HIV-1 Ribonucleic Acid [RNA] >=50 Copies Per Millilter [mL]) Using Snapshot Algorithm at Week 48
Week 48

Frequently asked questions about Cabotegravir

What is Cabotegravir used for?

Cabotegravir is an investigational small molecule in Phase 3 clinical development for the treatment of HIV infections, including Human Immunodeficiency Virus and HIV Infections.
