AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with HIV-1 whose virus is already well controlled on Biktarvy (B/F/TAF). It compares switching to bictegravir/lenacapavir with staying on Biktarvy.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- HIV-1 infection with virus kept below 50 copies/mL at screening and in earlier tests.
- Earlier treatment
- Must have taken B/F/TAF for at least 6 months before screening. Must not have had lenacapavir before.
- Biomarker or test result
- HIV-1 RNA below 50 copies/mL. No known or suspected resistance to bictegravir or tenofovir alafenamide. Kidney function (eGFR) above 30 mL/min.
Main reasons for not taking part
- Pregnant or breastfeeding
- Chronic hepatitis B infection
- Active tuberculosis or other serious infection needing treatment through a vein
- Decompensated liver cirrhosis
- Active cancer needing systemic treatment

To evaluate the efficacy of switching to bictegravir/lenacapavir (BIC/LEN) (75/50 mg) fixed-dose combination (FDC) tablets versus continuing on bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) (50/200/25 mg) FDC tablets in virologically suppressed people with HIV-1Read full original descriptionShow less
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
To evaluate the efficacy of switching to bictegravir/lenacapavir (BIC/LEN) (75/50 mg) fixed-dose combination (FDC) tablets versus continuing on bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) (50/200/25 mg) FDC tablets in virologically suppressed people with HIV-1
Inclusion: Aged ≥ 18 years at screening; Currently receiving B/F/TAF for at least 6 months prior to screening; If plasma HIV-1 RNA measurements in the last 6 months prior to screening are available, all levels must be < 50 copies/mL; At least one documented HIV-1 RNA level measured between 6 and 12 months (± 2 months) prior to screening. This and any other HIV-1 RNA measurements documented in this period must be < 50 copies/mL; Plasma HIV-1 RNA levels < 50 copies/mL at screening; No documented or suspected resistance to BIC (mutations T66A/I/K, E92G/Q, G118R, F121Y, Y143C/H/R, S147G, Q148H/K/R, N155H/S, or R263K in the integrase gene); No documented or suspected resistance to tenofovir alafenamide (TAF; mutations K65R, K65N, K70E, Q151M or T69 insertion, or ≥ 3 of the following thymidine analog mutations [M41L, D67N, K70R, L210W, T215Y/F, K219Q/E/N/R] in the reverse transcriptase gene); Estimated glomerular filtration rate > 30 mL/min according to the Cockcroft-Gault formula for creatinine clearance (CLcr); Participants assigned female at birth and of childbearing potential who engage in heterosexual intercourse must agree to use protocol-specified methods of contraception.
Exclusion: Active, serious infections (other than HIV-1) requiring parenteral therapy < 30 days prior to randomization; Acute hepatitis < 30 days before randomization; Requirement for ongoing therapy with or prior use of any prohibited medications listed in Section 5.3 of the protocol; Participation or planned participation in any other clinical study (including observational studies) without prior approval from the sponsor; Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the participant unsuitable for the study or unable to comply with dosing requirements; Prior use of, or exposure to, LEN; Active tuberculosis infection; Chronic hepatitis B virus (HBV) infection, as determined by either: a) Positive HBV surface antigen and negative HBV surface antibody, regardless of HBV core antibody status, at the screening visit. b) Positive HBV core antibody and negative HBV surface antibody, regardless of HBV surface antigen status, at the screening visit; Known hypersensitivity to the study drug, its metabolites, or any formulation excipient; History of or current clinical decompensated liver cirrhosis (eg, ascites, encephalopathy, or variceal bleeding); Active malignancy requiring acute systemic therapy; Positive serum pregnancy test or pregnant at screening or a positive pregnancy test prior to Day 1 randomization; Any of the following laboratory values at screening: a) Alanine aminotransferase > 5 × upper limit of normal (ULN) b) Direct bilirubin > 1.5 × ULN c) Platelets < 50,000/mm3 d) Hemoglobin < 8.0 g/dL; Participants under guardianship, curatorship, or legal protection may not participate in the study; Abnormal electrocardiogram (ECG) at the screening visit that is clinically significant as determined by the investigator; Breastfeeding (nursing).
