About this study
Official title: Phase 3 Double-blind Multicenter Randomized Active-Controlled Study to Evaluate the Safety and Efficacy of Bictegravir/Lenacapavir Versus Biktarvy® (Bictegravir/Emtricitabine/Tenofovir Alafenamide) in Virologically Suppressed People With HIV-1
The goal of this clinical study is to learn more about the effects of switching to the study drugs, bictegravir (BIC)/lenacapavir (LEN), fixed-dose combination (FDC) versus current therapy bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) FDC in people living with HIV-1 (PWH) who are successfully treated with B/F/TAF (virologically suppressed).
The primary objective of this study is to evaluate the efficacy of switching to BIC/LEN (75/50 mg) FDC tablets versus continuing on B/F/TAF (50/200/25 mg) FDC tablets in virologically suppressed PWH.

| Study group | Role | What they receive |
|---|---|---|
| Blinded Phase: Treatment Group 1: BIC/LEN 75/50 mg | Experimental | Participants will switch from bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) 50/200/25 mg fixed-dose combination (FDC) tablets to bictegravir/lenacapavir (BIC/LEN) 75/50 mg FDC tablets + placebo-to-match (PTM) B/F/TAF tablets, administered orally, once daily up to 48 weeks. Participants will also receive a 2-day oral pharmacokinetic (PK) loading dose of LEN 600 mg on Days 1 and 2, in addition to the daily doses of BIC/LEN 75/50 mg and PTM B/F/TAF tablets starting on Day 1.
At the end of blinded treatment (EBT) participants will enter the open label (OL) phase and continue to receive BIC/LEN 75 mg/50 mg FDC tablets through at least 48 weeks in the OL phase. At the OL Week 48, participants will be given an option to continue to receive BIC/LEN FDC tablets. Receives: Drug: Bictegravir/Lenacapavir (BIC/LEN) FDC; Drug: Lenacapavir; Drug: Placebo to match B/F/TAF |
| Blinded Phase: Treatment Group 2: B/F/TAF 50/200/25 mg | Active comparator | Participants will continue with their B/F/TAF 50/200/25 mg tablets and start PTM BIC/LEN tablets on Day 1 administered orally, once daily up to 48 weeks. Participants will receive PTM oral LEN PK loading tablets for 2 days (2 PTM LEN tablets on Day 1 and on Day 2).
Participants who complete the EBT will be given an option to enter the OL phase to receive BIC/LEN FDC tablets. Receives: Drug: B/F/TAF; Drug: Placebo to match BIC/LEN FDC; Drug: Placebo to match Lenacapavir |
| Open-label Phase: BIC/LEN 75/50mg | Experimental | Participants from Treatment Group 1 will receive BIC/LEN FDC tablets through at least OL Week 48. At the OL Week 48 visit, participants from Treatment Group 1 will be given the option to continue to receive BIC/LEN FDC tablets. Participants in Treatment Group 2 who complete the EBT visit will be given the option to enter the OL phase to receive BIC/LEN FDC tablets. Participants from Treatment Group 2 who enter the OL phase will also receive a 2-day oral loading dose of LEN 600 mg (2 × 300 mg LEN on Day 1 and on Day 2).
All participants who enter the OL phase may continue to receive BIC/LEN FDC tablets daily until study drug is available or until Gilead Sciences (Gilead) elects to discontinue the study. Receives: Drug: Bictegravir/Lenacapavir (BIC/LEN) FDC; Drug: Lenacapavir |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Human Immunodeficiency Virus-1 Ribonucleic Acid (HIV-1 RNA) ≥ 50 Copies/mL at Week 48 as Determined by the United States Food and Drug Administration (US FDA) Defined Snapshot Algorithm
Participants who had the last available on-treatment HIV-1 RNA≥ 50 copies/mL in the Week 48 analysis window, or who did not have on-treatment HIV-1 RNA data in the Week 48 analysis window and participants who discontinued study drug prior to or in the Week 48 analysis window due to lack of efficacy, or who discontinued study drug prior to or in the Week 48 analysis window due to reasons other than adverse event (AE), death, or lack of efficacy and have the last available on-treatment HIV-1 RNA ≥ 50 copies/mL were included. The Week 48 window was between Days 295 and 378 (inclusively). Percentages were rounded off.
Measured: Week 48
Secondary outcomes (11)
Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 as Determined by the US FDA-Defined Snapshot Algorithm
Participants who had the last available on-treatment HIV-1 RNA < 50 copies/mL in the Week 48 analysis window were included. The Week 48 window for snapshot algorithm was between Days 295 and 378 (inclusively). Percentages were rounded off.

Primary outcome
Percentage of Participants With Human Immunodeficiency Virus-1 Ribonucleic Acid (HIV-1 RNA) ≥ 50 Copies/mL at Week 48 as Determined by the United States Food and Drug Administration (US FDA) Defined Snapshot Algorithm
Time frame: Week 48
Participants who had the last available on-treatment HIV-1 RNA≥ 50 copies/mL in the Week 48 analysis window, or who did not have on-treatment HIV-1 RNA data in the Week 48 analysis window and participants who discontinued study drug prior to or in the Week 48 analysis window due to lack of efficacy, or who discontinued study drug prior to or in the Week 48 analysis window due to reasons other than adverse event (AE), death, or lack of efficacy and have the last available on-treatment HIV-1 RNA ≥ 50 copies/mL were included. The Week 48 window was between Days 295 and 378 (inclusively). Percentages were rounded off.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Bictegravir/Lenacapavir (BIC/LEN) FDC, Lenacapavir and B/F/TAF in people with HIV-1-infection, run by Gilead Sciences at 104 sites in 14 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 104 sites in United States, Germany, Italy, Canada, Spain and 9 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Nov 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Human Immunodeficiency Virus-1 Ribonucleic Acid (HIV-1 RNA) ≥ 50 Copies/mL at Week 48 as Determined by the United States Food and Drug Administration (US FDA) Defined Snapshot Algorithm (time frame: Week 48). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06333808, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Nov 2026.
