Implementation Study of Lenacapavir Pre-exposure Prophylaxis for HIV Prevention
(PROPEL)
What this study is about
The goal of this observational study is to generate real-life information on the use of lenacapavir (LEN, YEZTUGO®, (YTG)) for pre-exposure prophylaxis (PrEP) across diverse clinical settings in the United States. The study will characterize how PrEP is initiated, used, and discontinued in routine clinical practice when LEN is added as PrEP option and will evaluate persistence on LEN PrEP.
View original scientific description
The goal of this observational study is to generate real-life information on the use of lenacapavir (LEN, YEZTUGO®, (YTG)) for pre-exposure prophylaxis (PrEP) across diverse clinical settings in the United States. The study will characterize how PrEP is initiated, used, and discontinued in routine clinical practice when LEN is added as PrEP option and will evaluate persistence on LEN PrEP. The primary objective of this study is to evaluate real-life persistence on LEN PrEP at Week 52 in diverse clinical settings in the United States.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Able to comprehend and provide a signed written informed consent, which must be obtained prior to initiation of screening study procedures;
- Willing and able to comply with all study requirements;
- Presents at a study site needing or wanting PrEP for HIV prevention as determined by local clinical practice guidelines and institutional protocols, including new PrEP users (PrEP naïve) and current or former users of oral (emtricitabine/tenofovir disoproxil fumarate (coformulated; Truvada®; F/TDF) or emtricitabine/tenofovir alafenamide (coformulated; Descovy®; F/TAF)) or injectable (LEN or cabotegravir (CAB)) PrEP who indicate interest in discussing PrEP methods that they are clinically eligible to receive;
- Eligible for LEN PrEP per standard of care procedures, for example, being HIV-1 negative at screening using a Food and Drug Administration (FDA) approved/cleared test for diagnosis of acute or primary HIV-1 infection;
- After PrEP counseling to learn about the advantages and disadvantages of various PrEP methods:
- Selects LEN PrEP as their chosen PrEP method; OR,
- Selects a different PrEP method or chooses not to start or continue PrEP. Key
Exclusion criteria
- Any other indication not already listed above that would make the participant ineligible for LEN PrEP at enrollment according to local guidelines, organizational protocols, US Prescribing Information (USPI) for the PrEP product, and/or Center for Disease and Control (CDC) guidance.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
