Study of Lenacapavir and Emtricitabine/Tenofovir Disoproxil Fumarate (F/TDF) for Prevention of HIV in People Who Inject Drugs (HPTN 103) (PURPOSE 4)

LAST UPDATED

April 29, 2024

Clinicaltrials.gov ID

NCT06101342

OVERVIEW

A Phase 2, Open-Label, Multicenter, Randomized Study to Evaluate the Pharmacokinetics and Safety of Twice Yearly Long-Acting Subcutaneous Lenacapavir for Pre-Exposure Prophylaxis in People Who Inject Drugs (PURPOSE 4)

PROTOCOL SUMMARY

The goals of this clinical study are 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 pre-exposure prophylaxis (PrEP) in people who inject drugs (PWID) in the United States (US). The primary objectives of this study are to characterize the pharmacokinetics (PK) of LEN and to evaluate the safety of LEN and F/TDF for PrEP in US PWID.
