CAPELLA Trial Summary

This trial will test lenacapavir as an addition to existing HIV treatments for people with drug resistance. The goal is to see if lenacapavir can help people with failing HIV treatment regimens.

Who is the study for?
This trial is for adults and adolescents living with HIV who have developed resistance to multiple drugs, specifically at least two agents from three or more of the main classes of antiretroviral (ARV) medications. Participants must be on a failing ARV regimen, have an HIV-1 RNA level ≥ 400 copies/mL, and not have an ongoing Hepatitis C infection.Check my eligibility
What is being tested?
The study tests Lenacapavir's effectiveness when added to a failing drug regimen in patients with multi-drug resistant HIV. It involves comparing placebo treatments against subcutaneous and oral forms of Lenacapavir alongside an Optimized Background Regimen (OBR).See study design
What are the potential side effects?
While specific side effects are not listed here, participants may experience adverse reactions related to Lenacapavir or their individual OBRs. These could include typical ARV-related side effects such as gastrointestinal issues, fatigue, potential liver toxicity, and possible injection site reactions.

3Treatment groups
Experimental Treatment
Placebo Group
Group I: Cohort 2: LenacapavirExperimental Treatment3 Interventions
Participants with a ≥ 0.5 log10 copies/mL HIV-1 RNA decline at the Cohort Selection Visit compared with the screening visit or with HIV-1 RNA < 400 copies/mL or if Cohort 1 is fully enrolled will receive oral lenacapavir 600 mg tablet on Days 1 and 2 and 300 mg tablet on Day 8, and will initiate an OBR on Day 1 in Oral Lead-in Period (Baseline to Day 14); followed by Maintenance Period where participants will receive SC lenacapavir 927 mg at Day 1 SC Visit (14 days after the first dose of oral lenacapavir) while continuing their OBR. Participants will receive their subsequent SC lenacapavir injection at the Week 26 Visit (relative to Day 1 SC). At Week 52 (relative to Day 1 SC), participants will be given the option to receive SC lenacapavir injections every 6 months (26 weeks), while continuing their OBR, until the product becomes accessible to participants through an access program or until Gilead elects to discontinue the study in the country.
Group II: Cohort 1A: LenacapavirExperimental Treatment4 Interventions
Participants with human-immunodeficiency virus-1 ribonucleic acid (HIV-1 RNA) ≥ 400 copies/mL and with a <0.5 log10 HIV-1 RNA decline at Cohort Selection visit compared with screening visit will receive oral lenacapavir 600 mg tablet on Days 1 and 2 and 300 mg tablet on Day 8, while continuing their failing regimen in blinded Functional Monotherapy Period (Baseline to Day 14); followed by unblinded Maintenance Period where participants will receive subcutaneous (SC) lenacapavir 927 mg and will initiate an OBR at Day 1 SC Visit (14 days after the first dose of oral lenacapavir). Participants will receive their subsequent SC lenacapavir injection at Week 26 Visit (relative to Day 1 SC). At Week 52 (relative to Day 1 SC), participants will be given an option to receive SC lenacapavir injections every 6 months (26 weeks), while continuing their OBR, until product becomes accessible to participants through an access program or until Gilead elects to discontinue the study in the country.
Group III: Cohort 1B: Placebo to LenacapavirPlacebo Group5 Interventions
Participants with HIV-1 RNA ≥ 400 copies/mL and with a <0.5 log10 HIV-1 RNA decline at the Cohort Selection visit compared with screening visit will receive oral lenacapavir placebo on Days 1, 2, and 8 while continuing their failing regimen in blinded Functional Monotherapy Period (Baseline to Day 14); followed by unblinded Maintenance Period where participants will receive oral lenacapavir 600 mg on Days 15 and 16 and 300 mg on Day 22, and will initiate an OBR on Day 15. At Day 1 SC (14 days after the first dose of oral lenacapavir), participants will receive SC lenacapavir 927 mg while continuing OBR. Participants will receive their next SC injection at the Week 26 Visit (relative to Day 1 SC). At Week 52 (relative to Day 1 SC), participants will be given an option to receive SC lenacapavir every 6 months (26 weeks), while continuing their OBR, until the product becomes accessible to participants through an access program or until Gilead elects to discontinue study in the country.
