Recruitment details

The study consists in 2 periods: Maintenance Period and Extension Period. Any participants who successfully completed 12 months of CAB+RPV treatment in the Maintenance Phase had the option to enter the Extension Phase and continued to have access to CAB + RPV.

Screening details

Total 687 were enrolled out of which 681 were included in intent-to-treat exposed population (ITT-E) that is all enrolled participants who received at least one dose of investigational product (IP) during the Maintenance Phase of the study (on or after Day 1). 6 participants did not receive any dose of IP.

Oral lead-in phase (OLI)

Arm description

Participants with human immunodeficiency viruses (HIV)-1 who chose oral lead in (OLI) received oral 30 milligram (mg) Cabotegravir (CAB) tablet + 25 mg Rilpivirine (RPV) tablet once daily (QD) for one month. At the month 1 visit, the last dose of oral CAB + RPV was given, followed by the first 600 mg CAB long-acting (LA) + 900 mg RPV LA intramuscular injection (IM), and second injection of CAB LA 600 mg + RPV LA 900 mg at month 2, and then subsequent injections once every 2 months (Q2M) until Month 12 (Maintenance Phase). The participants had the option to continue the regimen in the Extension Phase.

Notes
[2] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
Justification: The participants in Oral lead-in phase (OLI) group and Direct to injections (D2I) group received same treatment regimen in both Maintenance and Extension Periods, hence data was summarized by Maintenance Period and by Maintenance+Extension Period. The Biktarvy (BIK) group was followed only in Maintenance Period, since it was dissolved at the start of Extension Phase, when participants transitioned to Switch Q2M Group or commercial available treatments, based on protocol criteria.

Justification: Extension Period followed the participants from Oral lead-in phase (OLI), Direct to injections (D2I) and the Switch Q2M groups. The data for Oral lead-in phase (OLI) and Direct to injections (D2I) groups was summarized and presented by Maintenance Period and by Maintenance+Extension Period, hence were not added in this period. The data for Switch Q2M group was summarized and presented only for Extension Period, as this group was formed at the start of Extension Period.

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 ^[1]

End point description

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.

Notes
[1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
Justification: As per study design, the endpoints were presented for OLI + D2I arms combined as Q2M. Whereas, the baseline period was separated as OLI and D2I.

Percentage of participants with plasma HIV-1 RNA <50 c/mL at Month 6/5 - ITT-E Population ^[8]

End point description

Percentage of participants with plasma HIV 1 RNA < 50 c/mL was assessed using the FDA snapshot algorithm. For the Q2M arm, data from the Q2M OLI participants at Month 6 visit and Q2M D2I participants at Month 5 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 6 visit. Month 6/5 refers to the Month 6 (OLI and BIK) visit/Month 5 (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.

Change from baseline in renal biomarker: urine retinol binding protein 4 (microgram per liter (ug/L)) ^[20]

End point description

Serum samples were collected to evaluate renal specific biomarkers: urine retinol binding protein 4. Baseline value is defined as latest pre-treatment assessment with a non-missing value, including those from unscheduled visits. Change from baseline is defined as post-dose visit value minus baseline value. For the Q2M arm, data from the Q2M OLI participants at Month 6 and 12 visit and Q2M D2I participants at Month 5 and 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 6 and 12 visit. Month 6/5 refers to the Month 6 (OLI and BIK) visit/Month 5 (DTI) visit.

End point description

The homeostatic model assessment (HOMA) is a method used to quantify insulin resistance. HOMA-IR is calculated as fasting insulin microunits per liter (microU/L) multiplied by fasting glucose (nmol/L) divided by 22.5. Higher HOMA-IR values indicate increased insulin resistance; values <2 is generally regarded as normal. Baseline value is defined as latest pre-treatment assessment with a non-missing value, including those from unscheduled visits. Change from baseline is defined as post-dose visit value minus baseline value.

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.

[31] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
Justification: As per study design, the endpoints were presented for OLI + D2I arms combined as Q2M. Whereas, the baseline period was separated as OLI and D2I.

Change from month 2/1 in dimension scores using perception of injection (PIN) questionnaire - Q2M ^[32]

End point description

The PIN questionnaire was used to explore the dimension scores based on 4 dimensions including acceptance of injection site reactions (ISRs), Bother from ISRs, Leg movement and Sleep categories. Domain scores were calculated as a mean of all items with the domain. The PIN response options range from 1 (totally acceptable) to 5 (not at all acceptable). This endpoint was only planned to be analyzed for Q2M arm. Month 2/1 refers to the Month 2 (OLI and BIK) visit/Month 1 (DTI) visit.

End point description

The PIN questionnaire was used to explore the individual item scores based on anxiety before, pain, satisfaction, anxiety after and willingness categories. The items in the scale are rated on a 5-point scale and questions are phrased in such a way as to ensure that 1 is very dissatisfied and 5 was very satisfied. This endpoint was only planned to be analyzed for Q2M arm. Month 2/1 refers to the Month 2 (OLI and BIK) visit/Month 1 (DTI) visit.

Were there any global substantial amendments to the protocol? Yes

30 Jun 2020

The primary reason for protocol amendment 01 is to add minor clarifications to address study completion, PK collection, and endpoint timings. Country-specific details were added to Appendix 10 to address UK MHRA requirements. The protocol short title was updated. Corrections to typographical errors in protocol text and title were made throughout.

08 Sep 2021

The primary reason for protocol amendment 02 is to address and clarify comments raised during the course of the study and to implement country specific changes following regulatory review.

10 Feb 2022

The primary reason for protocol amendment 03 is to address and clarify comments raised during the course of the study.

Were there any global interruptions to the trial? No
