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

Study Overview
=================
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.

(ii) 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 enrolment. (b) 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 the methods of contraception. Capable of giving signed informed consent. Must have been on oral CAB 30 mg plus RPV 25 mg regimen through at minimum Week 300 of the LATTE study as per LATTE protocol dosing requirements and until Day 1 of the POLAR study. Any disruptions in dosing during LATTE must be discussed with the Medical Monitor for a final determination of eligibility. Plasma HIV-1 RNA <50 c/mL at Week 300. If participant has plasma HIV-1 RNA >= 50 c/mL at Week 300 in LATTE, a single repeat to determine eligibility may be allowed ONLY after consultation with the medical monitor. Exclusion Criteria: During the last 6 months of participation in LATTE, consecutive (2 or more sequential) plasma HIV-1 RNA measurements >=50 c/mL. During the last 6 months of participation in LATTE, any HIV-1 RNA measurement >=200 c/mL.

Participants with moderate to severe hepatic impairment determined by Child-Pugh classification. 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 enrolment if the Investigator believes the risk of seizure recurrence is low. 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.

Evidence of Hepatitis B virus (HBV) infection based on the results of testing for Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (anti-HBc), Hepatitis B surface antibody (anti-HBs) and HBV DNA as follows; Participants positive for HBsAg are excluded; participants negative for anti-HBs but positive for anti-HBc (negative HBsAg status) and positive for HBV DNA are 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, following consultation with the medical monitor). Participants 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. 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 fibrosis- 4 (Fib-4) score will be used to verify eligibility where Fib-4 score >3.25 is exclusionary; Fib-4 scores 1.45 - 3.25 requires Medical Monitor consultation where the Fibrosis 4 Score Formula: age multiplied by aspartate amino transferase (AST) divided by platelets multiplied by square of alanine aminotransferase (ALT).

| Urine Albumin/Creatinine Ratio and Urine Protein/Creatinine Ratio | Urine samples were collected for the analysis of urine albumin/creatinine ratio and urine protein/creatinine ratio. | At Day 1 | 
| Absolute Values of Urine Creatinine | Urine samples were collected for the analysis of urine creatinine. | At Day 1 | 
| Absolute Values of Urine Phosphate | Urine samples were collected for the analysis of urine phosphate. | At Day 1 | 
| Absolute Values of Urine Specific Gravity | Urine samples were collected for the analysis of urine specific gravity. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. | At Day 1 | 
| Absolute Values of Urine Potential of Hydrogen (pH) | Urine samples were collected for analysis of urine pH. pH is calculated on a scale of 0 to 14, values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH of less than 7 is acidic and a pH of greater than 7 is basic. Normal urine has a slightly acidic pH (5.0-6.0). | At Day 1 | 
| Number of Participants With Treatment Emergent Genotypic Resistance | Plasma samples were collected and analyzed for genotypic resistance from participants who met confirmed virologic withdrawal criteria. | Up to Month 12 | 
| Number of Participants With Treatment Emergent Phenotypic Resistance | Plasma samples were collected and analyzed from participants who met confirmed virologic withdrawal criteria. | Up to Month 12 | 
| Change From Baseline in HIV Dependent Quality of Life (HIVDQoL - Self-completion Questionnaire Designed to Measure QoL in People Living With HIV) | HIVDQoL includes 2 overview items and 26 domain items. The 2 overview items: Item 1: 3(excellent) to -3(extremely bad); Higher score indicates better quality of life. Item 2: -3(very much better) to 1(worse); Lower score indicates better quality of life. The Weighted impact score was calculated for 26 individual domain items by multiplying impact score (-3[maximum negative impact] to +1[maximum 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 impact scores and dividing by the number of domain items. The ranges of weighted impact score and average impact score were from -9(maximum negative impact) to +3(maximum positive impact); 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). | Baseline (Day 1) and at Months 6 and 12 | 
| Change From Baseline in Treatment Satisfaction Score of HIV Treatment Satisfaction Status Questionnaire (HIVTSQs) | HIVTSQs total treatment satisfaction score is computed with 1-11 items. Items 1-11 are summed to produce score with possible range of 0 to 66. Higher the score, greater improvement in satisfaction with treatment; lower score, greater the deterioration in satisfaction with treatment. A score of 0 represents no change. The higher the score, the greater the improvement in treatment satisfaction as compared to the past few weeks. A smaller score represents a decline in treatment satisfaction compared to the past few weeks. Baseline value is defined as latest pre-treatment assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was defined as post-dose visit value minus Baseline value. | Baseline (Day 1) and at Months 6 and 12 | 
| Change From Baseline in Individual Item Score of HIVTSQs | HIVTSQs is a 12 item questionnaire. The individual item scores are rated as 6 (very satisfied, convenient, flexible, etc.) to 0 (very dissatisfied, inconvenient, inflexible, etc.). Higher scores represent greater treatment satisfaction as compared to the past few weeks. Change from Baseline is defined as post-dose value minus Baseline value. Baseline value is defined as latest pre-treatment assessment with a non-missing value, including those from unscheduled visits. | Baseline (Day 1) and at Months 6 and 12 | 
| Change in Treatment Satisfaction Over Time Using the HIV Treatment Satisfaction Change Questionnaire (HIVTSQc) | HIVTSQc (change version) total treatment satisfaction score is computed with 1-11 items. Items 1-11 are summed to produce score with possible range:-33 to 33. Higher scores represent greater improvement in treatment satisfaction compared to satisfaction with treatment received during the induction phase; lower scores represented deterioration in satisfaction with treatment. A score of 0 represents no change. A maximum of 5 items can be missing, the missing scores were imputed with the mean of the completed item scores. If 6 or more items are missing, then the overall treatment satisfaction scale score should not be computed and remain missing. | At Month 12 |
