入选标准

•Sub-study specific Inclusion Criteria:
•Capable of giving sub-study specific informed consent.
•Eligible participants must have been on CAB LA + RPV LA regimen for a minimum of 152 weeks while on the ATLAS2-M study. Any disruptions in dosing during ATLAS2-M must be discussed with the Medical Monitor for a final determination of eligibility into the sub-study.
•Plasma HIV-1 RNA <50 copies/mL at Sub-Study Screening.
•Inclusion criteria detailed for the ATLAS-2M main study apply to the sub-study:
•A female participant is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotropin [hCG] test) not lactating, and at least one of the following conditions applies:
•Non-reproductive potential defined as:
•Pre-menopausal females with one of the following:
•i. Documented tubal ligation ii. Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion iii. Hysterectomy iv. 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. 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.
•Reproductive potential and agrees to follow one of the options listed in the Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) from 30 days prior to the first dose of study medication, throughout the study, for at least 30 days after discontinuation of all oral study medications, and for at least 52 weeks after discontinuation of CAB LA and RPV LA.
•The investigator is responsible for ensuring that participants understand how to properly use these methods of contraception.

排除标准

•Sub-study specific Exclusion Criteria:
•Participants with more than 1 plasma HIV-1 RNA measurement >=50 copies/mL to <200 copies/mL (virologic blip) within 24 weeks prior to sub-study Screening visit.
•Any Suspected Virologic Failure (HIV-RNA greater than [>]200 copies/mL as defined in during ATLAS-2M study.
•Participants planning to require oral bridging during participation in the ATLAS-2M sub-study.
•The participant has a tattoo or any dermatological condition overlying the thigh region which may interfere with interpretation of injection site reactions.
•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.
•Exclusion criteria detailed for the ATLAS-2M main study apply to the sub-study:
•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 Cluster of Differentiation 4 positive (CD4+) counts <200 cells per microliter are not exclusionary.
•Participants with moderate to severe hepatic impairment.
•Any pre-existing physical or mental condition (including substance use disorder) which, in the opinion of the Investigator, may interfere with the participant's ability to comply with the dosing schedule and/or protocol evaluations or which may compromise the safety of the participant.
•Participants determined by the Investigator to have a high risk of seizures, including participants with an unstable or poorly controlled seizure disorder. A participant 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.
•Participants who, in the investigator's judgment, pose a significant suicide risk. Participant's recent history of suicidal behavior and/or suicidal ideation should be considered when evaluating for suicide risk.
•Unstable liver disease (as defined by any of the following: presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice or cirrhosis), known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator assessment).
•History of liver cirrhosis with or without hepatitis viral co-infection.
•Ongoing or clinically relevant pancreatitis.
•Clinically significant cardiovascular disease, as defined by history/evidence of congestive heart failure, symptomatic arrhythmia, angina/ischemia, coronary artery bypass grafting (CABG) surgery or percutaneous transluminal coronary angioplasty (PTCA) or any clinically significant cardiac disease.
•Ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical intraepithelial neoplasia; other localized malignancies require agreement between the investigator and the Study medical monitor for inclusion of the participant prior to randomization.
•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 PK 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 lesser than or equal to (<=)325 mg or hereditary coagulation and platelet disorders such as hemophilia or Von Willebrand Disease.
•Any verified Grade 4 laboratory abnormality. A single repeat test is allowed during the Screening phase to verify a result.
•Any acute laboratory abnormality at Screening, which, in the opinion of the investigator, would preclude the participant's participation in the study of an investigational compound.
•Participant has estimated creatine clearance <50mL per minute per 1.73 square meter via Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) Method.
