简要总结
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.

研究组 & 干预措施
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.
If participants choose to not receive additional LEN injections, they will continue onto the pharmacokinetic (PK) Tail Phase for up to 52 weeks.
干预措施: Lenacapavir Tablet (Drug)
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.
If participants choose to not receive additional LEN injections, they will continue onto the PK Tail Phase for up to 52 weeks.
