Study of Lenacapavir as a Once-Yearly Injection for HIV Pre-exposure Prophylaxis (PrEP)
Purpose
The goal of this clinical study is to learn more about the study drug lenacapavir (LEN), safety, tolerability, and pharmacokinetics (how LEN is absorbed, modified, distributed, and removed from the body of the participants) of once-yearly intramuscular for HIV pre-exposure prophylaxis (PrEP) in people with an indication for PrEP. The primary objective of this study is to evaluate the pharmacokinetics (PK) and the safety and tolerability of intramuscular (IM) every 12 months (Q12M) LEN for PrEP among people with an indication for PrEP.

Study Design
- Phase
- Phase 3
- Study Type
- Interventional
- Allocation
- Non-Randomized
- Intervention Model
- Single Group Assignment
- Intervention Model Description
- It is a single arm study that means all participants will receive LEN. However, the study provides LEN in 2 phases, therefore, the two phases are reported as 2 separate arms.
- Primary Purpose
- Prevention
- Masking
- None (Open Label)
Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Lenacapavir (LEN) |
Participants with an indication for pre-exposure prophylaxis will receive for approximately 52 weeks: - LEN 3000 mg injection once on Day 1 - Oral LEN 600 mg on Day 1 and Day 2 during the Main Study Period Participant will receive additional oral LEN if IM injection are not available. |
|
|
Experimental LEN Extension Phase |
Participants with an indication for pre-exposure prophylaxis will receive LEN 3000 mg injection once on Day 1 (approximately one year after their initial dose) during the Extension Phase. Participants will receive oral LEN if IM injections are not available. |
