Active clinical trials for "HIV Infections"

The purpose of this study was to determine the effects of nevirapine on the steady state pharmacokinetics of fluconazole and to assess the steady-state pharmacokinetics of nevirapine when given in combination with fluconazole.

The purpose of this study is to demonstrate non-inferiority in efficacy while switching to a once-daily single-tablet regimen containing darunavir (DRV)/ cobicistat (COBI)/ emtricitabine (FTC)/ tenofovir alafenamide (TAF) (D/C/F/TAF tablet) relative to continuing the current regimen consisting of a boosted protease inhibitor (bPI) combined with tenofovir disoproxil fumarate (FTC/TDF) in virologically-suppressed (human immunodeficiency virus type 1 ribonucleic acid [HIV-1 RNA] concentrations less than [<] 50 copies per milliliter [copies/mL]) HIV-1 infected participants.

This study will compare safety, efficacy, and tolerability of a two drug regimen of dolutegravir (DTG) plus (+) lamivudine (3TC) administered once daily with DTG plus two nucleoside reverse transcriptase inhibitors (tenofovir disoproxil fumarate [TDF]/emtricitabine [FTC] fixed dose combination [FDC]) administered once daily in human immunodeficiency virus (HIV) 1 infected adult participants that have not previously received antiretroviral therapy. The study is designed to demonstrate the non inferior antiviral activity of DTG + 3TC regimen to that of DTG + TDF/FTC FDC and will characterise the long term antiviral activity, tolerability and safety of DTG plus 3TC through Week 148. Approximately, 700 participants will be randomised 1:1 to receive DTG + 3TC or DTG + TDF/FTC FDC. Participants will be stratified by screening HIV 1 ribonucleotide nucleic acid (RNA) levels and by screening CD4+ (cluster of differentiation 4) cell count.

Background: In most people infected with human immunodeficiency virus (HIV), their immune system cannot control HIV infection. They need drugs called combination antiretroviral therapy (cART) to control the HIV. When people stop cART treatment, their immune system cannot control the infection again. They can also become resistant to cART and have lasting side effects. Researchers want to test if the drug vedolizumab is effective at controlling HIV infection without the need for cART. Objective: To test if vedolizumab is safe and can control the amount of HIV in the blood when cART is not taken. Eligibility: People ages 18-65 who have HIV and are being treated with cART Design: Participants will be screened with: Physical exam Medical history Electrocardiogram: Soft, sticky patches on the chest, arms, and legs measure heart activity. Blood and urine tests Participants will have a baseline visit. This will be 2-5 hours each day for 1-2 days. It will include repeats of the screening tests and: Leukapheresis: Blood is removed through a needle in the arm. A machine separates the white blood cells from the blood. The rest of the blood is returned to the participant. Neurologic exam: The nerves and reflexes are tested. First vedolizumab infusion through an arm vein Participants will have visits every 4 weeks for 30 weeks. These will include: Vedolizumab infusions Repeats of baseline tests Participants will have more visits for blood draws. Participants will keep taking cART until after the week 22 infusion. After discontinuing cART at study week 22, participants will be seen every two weeks to monitor the CD4 count and the level of HIV in the blood. Some of these visits will occur in between infusion visits and will only take about 1 hour to complete. cART will be restarted if a participant's HIV levels go up to high, or if their CD4 cell counts decreases by too much. For the follow-up phase, participants will have visits every 4 weeks for 24 weeks. These will include blood tests and a physical exam. ...

A phase I absolute bioavailability study of BMS-626529 following oral and intravenous dosing

This study is a Phase IIa, randomized, multi-site, two-arm, double-blinded study to evaluate the safety, tolerability, and acceptability of GSK1265744 long acting injectable formulation (744 LA) in adult male subjects. To evaluate the safety and tolerability of the injectable agent, 744 LA (800 milligrams (mg) dose administered at three time points at 12 week intervals) through Week 41 in HIV-uninfected men. Eligible participants will be randomized in a 5:1 ratio to receive 744 LA or matching placebo. Participants will receive daily oral 744 (30 mg tablets) or matching placebo for 4 weeks during the Oral Phase of the study, followed by a one week washout period. Following safety lab assessments from the Oral Phase, participants will enter the Injection Phase and receive Intramuscular (IM) injections of 744 LA or placebo at three time points at 12 week intervals. IM injections will consist of 800 mg of 744 or a matching control

This study is a 48-week, Phase IIIb, randomly assigned, open-label, active-controlled, multicenter, parallel group, non-inferiority study. This study is designed to demonstrate the non-inferior antiviral activity of switching to the Abacavir (ABC) 600 milligrams (mg)/Dolutegravir(DTG) 50 mg/Lamivudine (3TC) 300 mg fixed-dose combination (FDC) compared with continuing the subject's current suppressive regimen through 24 weeks. The study will be conducted in approximately 538 Human Immunodeficiency Virus -1 (HIV-1) infected individuals who are on stable suppressive combination antiretroviral therapy (cART) with 2 Nucleoside reverse transcriptase inhibitors (NRTIs) plus either a protease inhibitor (PI), an non-nucleoside reverse transcriptase inhibitor (NNRTI), or an integrase inhibitor (INI). Eligible subjects will be randomly assigned 1:1 to continue their current regimen (approximately 269 subjects) or be switched to ABC/DTG/3TC FDC (approximately 269 subjects) once daily for 24 weeks. At Week 24, individuals originally randomly assigned to continue their current regimen will switch to ABC/DTG/3TC FDC and be followed for an additional 24 weeks. Individuals initially randomly assigned to ABC/DTG/3TC FDC will continue on that treatment arm for an additional 24 weeks. A pharmacokinetic (PK) substudy will be conducted at a small number of sites (approximately 10) to evaluate predose DTG concentrations as well as residual drug concentrations of efavirenz (EFV), nevaripine (NVP), amprenavir (APV) and tipranavir (TPV) in a subgroup of subjects who switch from EFV, NVP, fosamprenavir/ritonavir (FPV/r) or tipranavir/ritonavir (TPV/r).

The purpose of the study is to demonstrate the noninferiority of Algeron in combination with ribavirin compared to PegIntron in combination with ribavirin in treatment of chronic hepatitis C in Human Immunodeficiency Virus-1 infected patients

The study hypothesis is that cenicriviroc will improve cognition in HIV infected individuals with cognitive impairment. The investigators will study the effect of cenicriviroc on cognition in 24 subjects over a 24 week period.

The primary objective of this study is to evaluate whether an intervention that involves the medication naltrexone, will reduce drinking and improve health outcomes in women with HIV infection and hazardous drinking. Our central hypotheses are that, compared to women who receive placebo (sugar pill containing no medicine), women who receive naltrexone will have decreased rates of hazardous drinking, improved HIV medication adherence, less rapid disease progression, and reduced sexual risk behavior. The study design will involve 240 HIV-infected women with hazardous drinking, who will be recruited from HIV clinics, neighborhoods and referrals in Miami, Florida. Eligible women will receive either a daily pill containing naltrexone (50mg) or an identical-appearing placebo for four months. All participants will receive encouragement and feedback related to their drinking regardless of medication assignment. The study participants will be assessed at two, four and seven months after enrollment. The proposed work is innovative because pharmacologic treatment for alcohol has not been evaluated in HIV-infected women. If our hypotheses are confirmed, the study findings would transform the approach to hazardous drinking within clinics serving HIV-infected women.
