Active clinical trials for "HIV Infections"

Background: When there is a threat to the body, the immune system triggers inflammation. Too much inflammation can damage the body or cause painful symptoms. Some people with HIV feel sick after they start HIV drugs because their recovering immune systems cause too much inflammation. Or their immune systems can become activated all the time. This can cause serious health problems. Researchers want to test if the drug CC-11050 helps treat inflammation in people taking HIV drugs. Objectives: To test if CC-11050 is safe and well-tolerated for people with HIV who are taking HIV drugs. To see if it reduces inflammation. Eligibility: People ages 18 and older with HIV who have been on antiretroviral therapy for at least 1 year. Design: Participants will be screened with: Medicine review Physical exam and medical history Blood and urine tests Chest x-ray Electrocardiogram (ECG): Soft electrodes on the skin record heart signals. Participants will be randomly assigned to take capsules of either CC-11050 or a placebo. They will take the capsules every day for 12 weeks. They will continue to take their HIV drugs. Participants will have a baseline visit within 2 months of screening. This includes: Physical exam and medical history Blood and urine tests ECG Leukapheresis: Blood is removed by a needle in one arm and passed through a machine that removes white blood cells. The rest of the blood is returned through a needle in the other arm. Participants will have follow-up visits 2, 4, 8, 12, and 16 weeks after the baseline visit. These may include repeats of some of the baseline tests.

The purpose of this study is to explore a possible link between the autonomic nervous system and immune function in patients with HIV. Sometimes HIV can cause these nerves to function abnormally, this is called HIV-associated autonomic neuropathy (HIV-AN). HIV-AN is a condition that is different from person to person. In some people it causes no symptoms and is not harmful, in others it may cause symptoms such as dizziness or lightheadedness, nausea, vomiting, diarrhea, constipation, or problems urinating. Most people with HIV-AN don't know that they have it. One of the important nerves in the autonomic nervous system is the vagus nerve. Abnormal function of the vagus nerve may cause stomach and intestinal slowing, which could lead to an overgrowth of bacteria. The body senses these bacteria and tries to fight them, leading to inflammation. In this study the researchers will test whether abnormal function of the vagus nerve in HIV is associated with stomach slowing and overgrowth of bacteria, and if a drug called pyridostigmine can help.

This study assessed the safety and tolerability of enfuvirtide in participants with advanced HIV genotype 1 (HIV-1) disease. Eligible participants who failed treatment with regimens containing at least one product from each anti-retroviral class, or had experienced intolerance to previous anti-retroviral regimens received enfuvirtide, 90 milligrams (mg) subcutaneously (SC) twice daily (BID) as long as there were no enfuvirtide related treatment limiting toxicities and participants benefited from study treatment as per investigator's discretion. The anticipated time on study treatment was based on the commercial availability of enfuvirtide in Thailand, and the target sample size was 30 individuals.

Sleep problems, such as insomnia, are more frequent and intense in individuals living with HIV. These sleep difficulties can increase the difficulties in thinking and concentrating. Digital cognitive behavioral therapy for insomnia (dCBT-I) is a computer-based treatment intervention that provides strategies to improve sleep. This intervention has been shown to improve sleep and daytime function (concentration, productivity) in people with insomnia. However, the effects of this intervention in people living with HIV are unknown.

The proposed study, for HIV positive alcohol dependent adults currently taking naltrexone, is a pilot randomized controlled trial (RCT) examining the outcomes of a 12-week behavioral support program delivered via text-messaging. It is expected that the text messaging intervention will reduce alcohol use and HIV-risk behaviors. The investigators also hypothesize that the intervention will improve adherence to HIV treatment and naltrexone. To test the effects of the intervention on these target outcomes, 25 participants receiving the text messaging intervention will be compared to 25 participants receiving an informational pamphlet. The pamphlet will contain information about the importance of HIV treatment adherence, reducing HIV risk behaviors, and health consequences associated with alcohol use. By providing support to maximize HIV treatment regimen and naltrexone adherence, coupled with coping skills to promote abstinence from alcohol, the text messaging intervention may provide a promising, cost-effective, and easily deployable behavioral support program for alcohol users who are HIV-infected.

This pilot single arm, single site, open-labeled switch study seeks to enroll thirty (30) HIV positive patients infected with CCR5 tropic virus that have achieved an undetectable viral load on a non-Selzentry®-containing regimen [Protease Inhibitor (PI)/Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI)/Integrase Inhibitor plus 2 Nucleoside Reverse Transcriptase Inhibitor (NRTI)] and switch them to once-daily Selzentry® (600mg qd) plus the same 2 NRTIs.

Antiretroviral therapy (ART) can reduce HIV to very low levels in the blood, but it cannot cure HIV infection because a small amount of virus remains in cells as a hidden (latent) form. The purpose of this study was to evaluate the safety and efficacy of single dose and multiple dose administration of romidepsin (RMD) in HIV-infected adults.

1. PROTOCOL SUMMARY This is a prospective, randomized open-label, 2 arm, 3-phase trial to compare the 48-weeks virological response of two different regimens containing abacavir/lamivudine (abacavir/lamivudine +darunavir/ritonavir (DRV/r) vs abacavir/lamivudine + raltegravir (RAL) in antiretroviral therapy naive, HIV+ individuals presenting for care with CD4+ counts < 200/mm3. 1.1 Clinical Objectives: Primary Objective: To compare the 48-week virological response to two different regimens containing abacavir/lamivudine (abacavir/lamivudine +darunavir/ritonavir (DRV/r) vs abacavir/lamivudine + raltegravir (RAL) in antiretroviral therapy naive, HIV+ individuals presenting for care with CD4+ counts < 200/mm3. Secondary Objective: a) To compare immunological response at 48 weeks; b) To determine the safety and tolerability of the 2 regimens. 1.2 Study population: 350 in/out patients 1.3 Outcome Primary Endpoint Proportion of patients with HIV RNA<50 copies/mL after 48 weeks Secondary Endpoints(s) Change in CD4+ cell count from baseline through week 48 Time to virological rebound 1.4 Study design: Multicentre, parallel group, randomised, open label, non-inferiority study 1.5 Treatment regimens: Arm A: abacavir/lamivudine 1 tablet once a day + raltegravir 400 mg (1 tablet twice a day) Arm B: abacavir/lamivudine 1 tablet once a day + ritonavir 100 mg + darunavir 800 mg once a day. All drugs have been approved for the treatment of HIV infection. The study population will consist of 350 HIV-positive, HLA B5701-negative patients. At baseline, patients will be randomized 1:1 to start abacavir/lamivudine plus either raltegravir or darunavir/ritonavir. Randomization will be stratified on the basis of the screening CD4+ cell count (≤100 vs ≥100 cells/µL), to ensure balance across treatments groups 1.7 Criteria for Safety: Adverse events and laboratory assessments. 1.8 Statistical analysis: As this is a non-inferiority trial, we will calculate the difference in the proportions of patients experiencing the primary outcome in the two treatment arms and will calculate a 95% confidence interval for this. Non-inferiority of the raltegravir arm will be demonstrated if the lower limit of the 95% confidence interval is greater than -12%. In case non-inferiority will be met, analyses for superiority will be performed.

This is a single-center, randomized, open-label, 3 parallel treatment study in healthy adult subjects to assess the relative bioavailability of new formulations of GSK1265744 LAP 400 mg intra muscular compared to the current GSK1265744 LAP 400 mg nanomilled formulation. This study will evaluate LAP formulations of GSK1265744 with different particle sizes. Following a 14 day lead in period with oral GSK1265744, forty-five subjects will receive 400 mg of one of three GSK1265744 formulations which vary in particle size from 200 nm to 5 um by intramuscular injection. Samples for determination of GSK1265744 concentrations will be collected for 12 weeks post-injection. Safety will be evaluated by adverse event recording and laboratory values at frequent intervals throughout the trial. A subgroup of 12 subjects will receive a 3 mg dose of oral midazolam at baseline on Day-29 and then again on the last day of the oral GSK1265744 lead in period to evaluate the effect of GSK1265744 on CYP3A enzymes. The subjects will undergo follow-up evaluations for a minimum of 12 weeks.

In this study, investigators propose to randomize 165 human immunodeficiency virus positive patients to one of three 16-week treatment conditions: (1) standard care; (2) standard care + cell phone-based adherence reminders; or (3) standard care + cell phone-based adherence reminders and contingency management. In this latter condition, patients will earn reinforcement for sending in time- and date-stamped self videos of antiretroviral therapy medication ingestion. Primary outcomes will include viral loads and self-report measures of adherence, and effects will be evaluated both during the treatment period and throughout a one-year follow-up. Investigators hypothesize that the cell phone reminder condition will improve adherence relative to standard care, and the cell phone reminder plus contingency management condition will have the best outcomes. Results from this study may have widespread implications for the use of cell phones as a novel technology to improve initial adherence to antiretroviral therapy, thereby reducing the spread of drug resistant human immunodeficiency virus strains to the community.
