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

Group Intervention Description Randomized Phase: Lenacapavir (LEN) Group Lenacapavir Tablet Participants 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) Group Emtricitabine/Tenofovir Disoproxil Fumarate (F/TDF) Participants will receive oral F/TDF (200/300 mg) daily for 52 weeks. PK Tail Phase: F/TDF Emtricitabine/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) Group Lenacapavir Injection Participants 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
Name Time Method Percentage of Participants Experiencing Treatment-emergent Clinical Laboratory Abnormalities First dose date up to 30 days post last dose at Week 78 Pharmacokinetic (PK) Parameter: Ctrough for Lenacapavir (LEN) at the End of Week 26 Week 26 Ctrough is defined as the concentration at the end of the dosing interval.
PK Parameter: Ctrough for LEN at the End of Week 52 Week 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 Responses Up 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 Responses Up to Week 52 To assess the acceptability of the study drug, participants will complete the questionnaire including a question on general acceptability of the assigned study drug on an ordinal 5-category scale with a response of: Completely unacceptable, Unacceptable, No opinion, Acceptable, or Completely acceptable.
Willingness to Use LEN and F/TDF as PrEP as Assessed by Percentage of Participants with Willingness to Use Questionnaire Responses Up to Week 52 To assess the willingness to use the study drug, participants will complete the questionnaire including a question on willingness to use the assigned study drug on an ordinal 5-category scale with a response of: Definitely Yes, Probably yes, Not sure/undecided, Probably No, or Definitely No.
