Active clinical trials for "HIV Infections"

This study is being done to evaluate the relationship between adherence to antiretroviral therapy (ART) and HIV drug concentrations in persons living with HIV (PLWH) that are taking tenofovir alafenamide (TAF). Adherence will be measured with an ingestible biosensor (digital pill). Antiretroviral drug concentrations will be measured in different types of blood cells.

The pilot study proposal aims to modulate craving and attentional bias towards smoking cues in 40 people living with HIV/AIDS (PLWHA) using transcranial magnetic stimulation (TMS), with functional MRI (fMRI) brain correlates. TMS is a form of noninvasive brain stimulation and modulates neural activity using tiny doses of focused electricity. For the study, participants would perform two cognitive tasks and neuroimaging before and after the TMS and investigators would compare changes in these paradigms with TMS. The investigators will also get a point of contact urine drug screen before study initiation. The investigators will aim to recruit 20 subjects in each arm of our trial (total of 40) from the BlueGrass HIV Clinic.

Project AProaCH is an open pilot trial of a cognitive behavioral therapy (CBT) for individuals with HIV with various psychological comorbidities, which the investigators call "syndemics". Syndemics are co-occurring psychosocial problems that interact with each other and with health behavior such as HIV sexual transmission risk behavior and adherence to self care.

The purpose of this study is to determine whether a modified form of the ARTAS (Antiretroviral Treatment and Access to Services) intervention, adapted for HIV patients who have fallen out of care, can be successful in re-engaging patients in care and reducing HIV-1 viral load.

HIV infection is associated the development of increased oxidative stress and deficiency of glutathione (GSH), the dominant endogenous antioxidant protein, but the underlying mechanisms contributing to GSH deficiency are hitherto unknown. Furthermore GSH metabolism has not been studied in HIV patients, in whom the burden of risk factors promoting oxidative stress is highest. Our previous studies in non-HIV human subjects with diabetes-related oxidative stress and GSH deficiency have demonstrated that the latter is due to decreased synthesis of GSH. Importantly, short-term dietary supplementation with the simple GSH precursor amino-acids cysteine and glycine, boosted GSH synthesis and cellular concentrations, corrected GSH deficiency, and reduced oxidative stress and oxidant damage. The current proposal will study whether (1) defective synthesis underlies GSH deficiency in patients with HIV, and will test a simple, inexpensive and rational therapy based on protein supplementation to improve GSH synthesis and concentrations and lower markers of oxidative stress and oxidant damage in these patients; (2) study if correction of GSH deficiency is asssociated with any changes in (a) impaired mitochondrial fuel oxidation in the fasted and insulin stimulated states; (b) insulin sensitivity; (c) body composition and anthropometry; (d) forearm muscle strength; (e) plasma biochemistry, and (f) quality of life indices in these subjects.

The objective of this study was to assess the bioequivalence of Roxane's zidovudine 300 mg tablet compared to GlaxoSmithKline's Retrovir® 300 mg tablet under fed conditions using a single-dose, randomized, 2-treatment, 2-period, 2-sequence crossover design.

The objective of this study was to assess the bioequivalence of Roxane's zidovudine 300 mg tablet compared to GlaxoSmithKline's Retrovir® 300 mg tablet under fasting conditions using a single-dose, randomized, 2-treatment, 2-period, 2-sequence crossover design.

This protocol serves to extend the successful treatment for HIV positive patients beyond the endpoints provided by the Phase 2b TaiMed Biologics-sponsored protocol TMB202 (entitled "A Phase 2b Randomized, Double-Blinded, 48-Week, Multicenter, Dose-Response Study of Ibalizumab Plus an Optimized Background Regimen in Treatment-Experienced Patients Infected with HIV-1 (Amended to 24 Week Study)"), for 24 weeks. Ibalizumab may be administered beyond 24 weeks under this protocol as supply permits and patients continue to demonstrate virologic response.

The purpose of this study is to measure the decay characteristics of HIV in the blood of patients after taking a combination of anti-HIV drugs, which includes a new class of anti-HIV drug, an integrase inhibitor. This study explores how this new combination of therapy reduces virus in various compartments of the body and immune system.

The intensification with maraviroc in recently HIV-1-infected patients of a preferred gold-standard triple therapy composed of raltegravir plus tenofovir/emtricitabine could accelerate the decay of the HIV-1 reservoir in latently infected cells established early in HIV-1 infection. This could provide further insight into this area, decrease the size of latent reservoir, and translate into clinical benefits for patients.
