Pioneering Research to Optimize Pre-exposure Prophylaxis (PrEP) Expansion With Lenacapavir (LEN)
Summary: 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 pri...
Lenacapavir Intensification to Disrupt HIV Reservoirs in Virologically Suppressed People With HIV Receiving Antiretroviral Therapy
Background: Antiretroviral viral therapy (ART) allows people with human immunodeficiency (HIV) to live long, healthy lives. But ART is not a cure. HIV can remain in the body, in infected cells called reservoirs. If a person stops taking ART, the HIV can rebound and reach high levels in their blood. Researchers want to find ways to reduce the size of HIV reservoirs in people taking ART.
Expanding PrEP Options Among Young MSM, Transgender and Non-binary Persons in Brazil: Incorporating Twice-yearly Lenacapavir for HIV Prevention - The ImPrEP LEN Brasil Study
Summary: The goal of this study is to learn how well long-acting lenacapavir works to prevent human immunodeficiency virus (HIV) infection in people at higher risk of getting HIV in Brazil. The study will also learn about safety, continued use over time, and whether people prefer this option compared to daily oral pre- exposure prophylaxis (PrEP). The main questions it aims to answer are: How many particip...
A Phase 3, Single-Arm Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Once-Yearly Intramuscular Lenacapavir for HIV Pre-exposure Prophylaxis (PrEP) in People With an Indication for PrEP
Summary: 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 pharmacokinet...
INCLUSION - Enhancing PrEP Uptake and Retention Among Latine Transgender Women and Gay, Bisexual, and Other Men Who Have Sex With Men in the South Using Long-Acting Injectable PrEP
Summary: The purpose of this project is to test a culturally-tailored, community-delivered long-acting injectable PrEP (lenacapavir) program for Latine gay and bisexual men (GBM) and transgender women (TGW). The objective is to evaluate whether this intervention demonstrates greater persistence on lenacapavir for Latine GBM and TGW compared with what has been observed historically at the Duke PrEP Clinic.
A Phase 2/3, Open-Label Study to Evaluate the Pharmacokinetics, Safety, and Antiviral Activity of Bictegravir/Lenacapavir in Children and Adolescents With HIV-1
Summary: The goal of this clinical study is to learn about the safety and tolerability of bictegravir/lenacapavir (BIC/LEN) and to learn how the study drug interacts with the body in virologically suppressed (VS) children and adolescents with human immunodeficiency virus type 1 (HIV-1) on a stable and complex antiretroviral (ARV) regimen. The study will also assess the safe loading dose of LEN and pharmaco...
A Phase 2, Open-label, Single-Arm Study to Evaluate the Pharmacokinetics, Safety, Tolerability, and Antiviral Activity of Long-Acting Lenacapavir in Combination With an Optimized Background Regimen in Treatment-experienced Adolescents and Children With HIV-1
Summary: The goal of this clinical study is to learn more about the study drug, lenacapavir (LEN). The study will assess the safety, tolerability, and efficacy of long-acting LEN when combined with other medicines in adolescents and children living with HIV-1 who weigh at least 35 kg and have been treated before for HIV-1. The study will also see how easy it is for participants to take LEN as injection or ...
Real World Use of Lenacapavir, as an add-on to an Optimized Background Regimen in France: a Retrospective Observational Study (LENAddOn)
Summary: For most people with HIV (PWH), an effective antiretroviral regimen can be devised. However, some PWH have multiple treatment failures due to viral resistance or unacceptable side effects to medication and no longer have durable viral suppression. People with multidrug-resistant HIV-1 are at increased risk for hospitalization, progression to acquired immunodeficiency syndrome, and death. Lenacapav...
