Study of Lenacapavir and Emtricitabine/Tenofovir Disoproxil Fumarate (F/TDF) in Prevention of HIV in Cisgender Women in the United States (HPTN 102)

Phase 2
Recruiting
Conditions
Pre-Exposure Prophylaxis of HIV Infection
Interventions
Drug: Emtricitabine/Tenofovir Disoproxil Fumarate (F/TDF)
Registration Number
NCT06101329
Lead Sponsor
Gilead Sciences
Brief Summary

The goal of this clinical study is to look at how lenacapavir (LEN) passes through the body and to assess the safety of LEN and emtricitabine/tenofovir disoproxil fumarate (F/TDF) for prevention of HIV in the cisgender women in the US.

The primary objectives of this study are: 1) to characterize the pharmacokinetics (PK) of LEN in United States (US) cisgender women; 2) to evaluate the safety of LEN and F/TDF for pre-exposure prophylaxis (PrEP) in US cisgender women; and 3) to evaluate the general acceptability of LEN injections and oral F/TDF in US cisgender women.

Randomized Phase: Lenacapavir (LEN) GroupLenacapavir TabletParticipants will receive subcutaneous (SC) lenacapavir (LEN) 927 mg on Day 1 and Week 26 and oral LEN 600 mg on Days 1 and 2.
Randomized Phase: Emtricitabine/Tenofovir Disoproxil Fumarate (F/TDF) GroupEmtricitabine/Tenofovir Disoproxil Fumarate (F/TDF)Participants will receive oral F/TDF (200/300 mg) daily for 52 weeks.
PK Tail Phase: F/TDFEmtricitabine/Tenofovir Disoproxil Fumarate (F/TDF)After the completion of the Randomized Phase, participants in LEN group will be transitioned to receive F/TDF and participants in F/TDF group will continue to receive F/TDF in the PK Tail Phase. All participants will receive F/TDF, once daily for 78 weeks beginning 26 weeks after the last LEN injection.
Randomized Phase: Lenacapavir (LEN) GroupLenacapavir InjectionParticipants will receive subcutaneous (SC) lenacapavir (LEN) 927 mg on Day 1 and Week 26 and oral LEN 600 mg on Days 1 and 2.
Primary Outcome Measures
NameTimeMethod
Percentage of Participants Experiencing Treatment-emergent Clinical Laboratory AbnormalitiesFirst dose date up to 30 days post last dose at Week 78
Pharmacokinetic (PK) Parameter: Ctrough for Lenacapavir (LEN) at the End of Week 26Week 26

Ctrough is defined as the concentration at the end of the dosing interval.

PK Parameter: Ctrough for LEN at the End of Week 52Week 52

Ctrough is defined as the concentration at the end of the dosing interval.

Percentage of Participants Experiencing Treatment-emergent Adverse Events (TEAEs)First dose date up to 30 days post last dose at Week 78
Satisfaction With Use of LEN and F/TDF as PrEP as Assessed by Percentage of Participants with Satisfaction Questionnaire ResponsesUp to Week 52

To assess the satisfaction with use of the study drug, participants will complete the questionnaire including a question on satisfaction with use of the assigned study drug on an ordinal 5-category scale with a response of: Very satisfied, Satisfied, Neutral, Dissatisfied, or Very dissatisfied.

General Acceptability of LEN and F/TDF as PrEP as Assessed by Percentage of Participants with Acceptability Questionnaire ResponsesUp to Week 52
