A Phase 3, Randomized, Active-Controlled, Double-Blind Clinical Study to Evaluate the Efficacy and Safety of MK-8527 Oral Once-Monthly as HIV-1 Preexposure Prophylaxis in Women
Summary: Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection. The goals of this study are to learn: * If taking MK-8527 once a month works to prevent HIV-1 infection better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day * About the safety of MK-8527 and if people tolerate it
Effect of CYP2B6 Genotype and Efavirenz on the Disposition and Pharmacodynamic of Methadone and Tizanidine in Healthy Volunteers
Summary: The main goal of this clinical study is to test how CYP2B6 genetic variations and efavirenz (cornerstone in HIV-1 therapy) dictate the disposition (PK) of CYP2B6 substrate (methadone) and PK and effect (PD) of CYP1A2 substrate (tizanidine). Specifically, the investigators will test whether efavirenz produces CYP2B6 genotype dependent unanticipated DDIs with CYP2B6 (methadone) and CYP1A2 (tizanidin...
A Phase 2 Randomized Cross-Over Design Study of the Early Metabolic Effects of Dolutegravir or Tenofovir Alafenamide in Healthy Volunteers
Background: People with HIV take drugs to keep the amount of virus in their body low. One type of these drugs, called integrase strand transfer inhibitors (INSTIs), can cause weight gain over time. Weight gain can cause diabetes, heart disease, and other serious issues. Researchers want to understand how INSTIs cause weight changes.
Investigating the Feasibility of Repurposing HIV Antivirals in Adults With Long Covid
Summary: The trial will test if two repurposed HIV antivirals can reduce symptom burden in adult participants with Long Covid compared to placebo. Viral infection and viral reactivation have been documented in Long Covid. Participants will be randomly allocated to receive antivirals, Truvada (tenofovir disoproxil/emtricitabine, TDF/FTC, Group 1) or Selzentry (Group 2), or a placebo (pill) (Group 3), taken ...
A Randomized, Double-Blind Evaluation of the Pharmacokinetics, Safety, and Antiviral Efficacy of Tenofovir Alafenamide (TAF) in Children and Adolescent Subjects With Chronic Hepatitis B Virus Infection
Summary: The goals of this clinical study are to compare the effectiveness, safety and tolerability of study drug, tenofovir alafenamide (TAF), versus placebo in teens and children with CHB and to learn more about the dosing levels in children.
DD-PrEP: Pharmacokinetic Evaluation of Single Dosing With Two F/TAF Tablets Among Healthy Volunteers
DD-PrEP: Pharmacokinetic Evaluation of Single Dosing With Two F/TAF Tablets Among Healthy Volunteers
Summary: The goal of this study is to evaluate the pharmacokinetics of a one-time dosing of two F/TAF tablets over a 14-day period.
Prefrontal Cortical Stimulation (PCS) for Severe Treatment Resistant Depression
Summary: This research study is designed to test if electrical stimulation of the surface of the brain in the frontal region will help treat depressive symptoms. Participants receive intermittent electrical stimulation to the brain, which involves surgically placing electric leads in between the tough fibrous membrane covering the surface of the brain and the surface of the brain itself. This type of stimu...
Phase III, Open-label, Randomized, Multicenter Trial EvaLuating the Non-inferiority of DORAvirine Versus DOlutegravir Based Antiretroviral Regimens in Treatment-naïve People Living With HIV-1 Infection
Summary: Phase III trial evaluating doravirine as an alternative to dolutegravir in treatment naïve people living with HIV-1 infection.
Impact of Two Types of Interventions (Ventrogluteal Versus Dorsogluteal Injection Site; Virtual Reality Headset: Presence or Absence) on Pain After Injections of Vocabria® (Cabotegravir) and Rekambys® (Rilpivirine) in Patients Infected With Human Immunodeficiency Virus -1
Summary: This is a multicenter, randomized, open-label study with a cross-over design. The objective of this project is to compare the intensity of pain induced by injectable antiretroviral (ARV) treatment (Cabotegravir® and Rilpivirine®) in patients infected with HIV-1, depending on the injection site and whether or not they are wearing a virtual reality headset. The reference group being the dorsogluteal...
A Phase I, Multi-centre, Open-label, Single Dose Escalation Study to Evaluate the Pharmacokinetics, Safety and Tolerability of Long-acting Cabotegravir Co-administered With Recombinant Human Hyaluronidase PH20 (rHuPH20) in Healthy Adult Volunteers
Summary: This is an open-label, dose-escalation study to investigate the safety, tolerability and pharmacokinetics (PK) of single subcutaneous (SC) administration of long acting (LA) Cabotegravir (CAB) 200 milligrams per milliliter (mg/mL) with Recombinant Human Hyaluronidase PH20 (rHuPH20) (Part A), a single-dose or repeat-dose SC or intramuscular (IM) administration of LA CAB (greater than or equal to) \...
Feasibility of CSF (Cerebrospinal Fluid) and Plasma ctDNA (Circulating Tumor Deoxyribonucleic) in BRAF (V-raf Murine Sarcoma Viral Oncogene Homolog B1)-Altered Glioma During Treatment With Plixorafenib
Summary: Evaluating the sensitivity and feasibility of using ctDNA assays optimized for detecting very low ctDNA counts from cerebrospinal fluid (CSF) and plasma. The investigators will evaluate the sensitivity of ctDNA from plasma and CSF at baseline (defined as Cycle1 Day1 (C1D1) pre-treatment) and over time in response to treatment with plixorafenib co-administered with cobicistat in BRAF-V600E mutant g...
IMplementation of CAB+RPV LA for People With HIV in Non-Metropolitan Areas: Addressing Adherence Barriers Through Learning and Evidence-Informed Strategies (IM-CAPABLE)
Summary: The goal of this implementation science study is to learn about the experience of receiving and providing cabotegravir + rilpivirine long-acting (CAB+RPV LA) injections as treatment for human immunodeficiency virus (HIV) for people who live a significant distance from an HIV provider. The main questions it aims to answer are: * Is CAB+RPV LA feasible and acceptable to patients and staff? * What ba...
