Study to Compare an Oral Weekly Islatravir/Lenacapavir Regimen With Bictegravir/Emtricitabine/Tenofovir Alafenamide in Virologically Suppressed People With HIV-1 (ISLEND-1)
EU CTIS ID: 2024-514046-37-00
What this study is testing
To evaluate the efficacy of switching to oral weekly islatravir (ISL; MK-8591)/lenacapavir (LEN; GS-6207) tablet regimen versus continuing B/F/TAF in virologically suppressed people with HIV (PWH) at Week 48
- Therapeutic confirmatory (Phase III)

Who can take part
You may be able to join if
- Participants 18 years of age or older at screening and able to understand and give written informed consent.
- HIV-1 RNA < 50 copies/mL for ≥ 6 months before screening, as documented by: • One HIV-1 RNA < 50 copies/mL immediately preceding the 24 week period prior to screening. • Within 24 weeks prior to screening, if HIV-1 RNA results are available, all levels must be < 50 copies/mL. • During the 6 to 12 months period prior to screening, transient detectable viremia ≥ 50 copies/mL is acceptable (“blip”), as long as it is not confirmed on 2 consecutive visits.
- Plasma HIV-1 RNA levels < 50 copies/mL at screening.
- Participants are receiving B/F/TAF for ≥ 6 months prior to screening and willing to continue until Day 1.
- Participants assigned female at birth and of childbearing potential who engage in heterosexual intercourse must agree to use protocol-specified methods of contraception as described in Appendix 11.5.
- Note: Other protocol defined Inclusion criteria may apply.
You likely can't join if
- Participants who meet any of the following exclusion criteria are not eligible to be enrolled in this study: 1) Prior virologic failure. 2) Prior use of, or exposure to, ISL or LEN. 3) Active, serious infections requiring parenteral therapy within 30 days before randomization. 4) Active tuberculosis infection. 5) Acute hepatitis within 30 days before randomization. 6) HBV infection, as determined below at the screening visit: a) Positive HBV surface antigen. OR b) Positive HBV core antibody and negative HBV surface antibody. Note: participants found to be susceptible to HBV infection (eg, negative hepatitis B surface antibody at the screening visit, regardless of prior HBV vaccination history) should be recommended to receive HBV vaccination.
- 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.
- Participants of childbearing potential (as defined in Appendix 11.5) who have a positive serum pregnancy test at screening or positive urine and serum pregnancy tests at Day 1 prior to study drug administration.
- Participants who plan to continue breastfeeding during the study.
- Requirement for ongoing therapy or use of any prohibited medications listed in Section 5.3 within 30 days prior to screening through the last dose of study drug.
- Note: Other protocol defined Exclusion criteria may apply.
