Non-reproductive potential defined as: pre-menopausal females with one of the following: documented tubal ligation; documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion; hysterectomy; Documented Bilateral Oophorectomy.

Postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels consistent with menopause (refer to laboratory reference ranges for confirmatory levels)]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment.

The investigator is responsible for ensuring that participants understand how to properly use these methods of contraception.

* Capable of giving signed informed consent. Eligible subjects or their legal guardians (and next of kin when locally required), must sign a written Informed Consent Form before any protocol-specified assessments are conducted.

* During participation in ATLAS, any HIV-1 RNA measurement >=200 copies/mL
* More than two total measurements of plasma HIV-1 RNA >=50 c/mL during participation in the ATLAS trial will require direct approval by the ATLAS-2M Medical Monitor and Study virologist for study participation.

For all subjects:

* Women who are pregnant, breastfeeding or plan to become pregnant or breastfeed during the study.
* Any evidence of a current Center for Disease Control and Prevention (CDC) Stage 3 disease except cutaneous Kaposi's sarcoma not requiring systemic therapy and CD4+ counts <200 cells/µL are not exclusionary.
* Subjects with moderate to severe hepatic impairment.

* Subjects determined by the Investigator to have a high risk of seizures, including participants with an unstable or poorly controlled seizure disorder. A subject with a prior history of seizure may be considered for enrollment if the Investigator believes the risk of seizure recurrence is low. All cases of prior seizure history should be discussed with the Medical Monitor prior to enrollment.
* All subjects will be screened for syphilis (rapid plasma reagin [RPR]). Subjects with untreated secondary (late latent) or tertiary syphilis infection, defined as a positive RPR and a positive treponemal test without clear documentation of treatment, are excluded. Subjects with a false positive RPR (with negative treponemal test) or serofast RPR result (persistence of a reactive nontreponemal syphilis test despite history of adequate therapy and no evidence of re-exposure) may enroll after consultation with the Medical Monitor. 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.
* The subject has a tattoo or other dermatological condition overlying the gluteus region which may interfere with interpretation of injection site reactions.
* Evidence of Hepatitis B virus (HBV) infection based on the results of testing at Screening for Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (anti-HBc), Hepatitis B surface antibody (anti-HBs) and HBV deoxyribonucleic acid (DNA) as follows:

Subjects positive for HBsAg are excluded; Subjects negative for anti-HBs but positive for anti-HBc (negative HBsAg status) and positive for HBV DNA are excluded. Note: Participants positive for anti-HBc (negative HBsAg status) and positive for anti-HBs (past and/or current evidence) are immune to HBV and are not excluded.

* Asymptomatic individuals with chronic hepatitis C virus (HCV) infection will not be excluded, however Investigators must carefully assess if therapy specific for HCV infection is required; participants who are anticipated to require HCV treatment within 12 months must be excluded. (HCV treatment on study may be permitted post Week 52, following consultation with the medical monitor).
* Subjects with HCV co-infection will be allowed entry into this study if: liver enzymes meet entry criteria; HCV Disease has undergone appropriate work-up, and is not advanced, and will not require treatment prior to the Week 52 visit. Additional information (where available) on participants with HCV co-infection at screening should include results from any liver biopsy, Fibroscan, ultrasound, or other fibrosis evaluation, history of cirrhosis or other decompensated liver disease, prior treatment, and timing/plan for HCV treatment; In the event that recent biopsy or imaging data is not available or inconclusive, the Fib-4 score will be used to verify eligibility: Fib-4 score >3.25 is exclusionary; Fib-4 scores 1.45 - 3.25 requires Medical Monitor consultation; Fibrosis 4 Score Formula:

* Any condition which, in the opinion of the Investigator, may interfere with the absorption, distribution, metabolism or excretion of the study drugs or render the participant unable to receive study medication.
* History or presence of allergy or intolerance to the study drugs or their components or drugs of their class. In addition, if heparin is used during pharmacokinetic sampling, participants with a history of sensitivity to heparin or heparin-induced thrombocytopenia must not be enrolled.
* Current or anticipated need for chronic anti-coagulation with the exception of the use of low dose acetylsalicylic acid (<=325 mg) or hereditary coagulation and platelet disorders such as hemophilia or Von Willebrand Disease.

Summary
Brief 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.
