Clinical Trial Summary

This Antiretroviral Therapy as Long Acting Suppression every 2 Months (ATLAS-2M) study is designed to demonstrate the non-inferior antiviral activity and safety of CAB LA + RPV LA administered every 8 weeks (Q8W) compared to CAB LA + RPV LA administered every 4 weeks (Q4W) over a 48-week treatment period in approximately 1020 adult HIV-1 infected subjects. Subjects will be divided in 2 groups; Group 1 will include subjects receiving current anti-retroviral (ART) standard of care (SOC) therapy whereas group 2 will include subjects currently receiving CAB LA + RPV LA Q4W in ATLAS study. Subjects in both groups will be randomized to receive CAB LA + RPV LA Q4W or Q8W. The study will be carried out in 3 phases including screening phase, maintenance phase and extension phase. Subjects choosing not to enter the Extension phase can complete their study participation at the Week 100 visit and enter into the 52-week Long-Term Follow-Up (LTFU) Phase as required. A sub-study in the ATLAS-2M study will evaluate the pharmacokinetics, tolerability and efficacy of CAB and RPV long acting injections following intramuscular administration in the Vastus Lateralis Muscle (thigh) in HIV-infected Adult Participants who have received at least three years of Gluteal Injections in this ATLAS-2M Study.

Participants with primary syphilis or early latent secondary syphilis (acquired within the preceding year) who have a positive RPR test and have not been treated may be treated during the screening period and if completion of antibiotic treatment occurs during the screening period, may be allowed entry after consultation with the Medical Monitor. If antibiotic treatment cannot be completed before the screening window ends, subjects may be rescreened once following completion of antibiotic therapy for primary or early latent secondary syphilis.

• Subjects who, in the investigator's judgment, pose a significant suicide risk. Subject's recent history of suicidal behavior and/or suicidal ideation should be considered when evaluating for suicide risk.
