Filter by:This study involves researching new approaches to treating HIV infection. Currently, HIV infection is treated with combinations of drugs called antiretrovirals. These drugs protect cells from infection by interfering with the viruses' ability to make copies of itself by infecting new target cells. Though these drugs are very effective, they cannot cure HIV infection and must be taken each and every day at prescribed doses to maintain their beneficial effect. This research study is investigating a new approach that involves an addition to existing medications. The study is investigating a medication called Poly-ICLC (Hiltonol®, Oncovir), which is an adjuvant. Adjuvants are medications that are designed to boost your body's immune responses resulting from a vaccine. The investigators want to test whether Poly-ICLC is an adjuvant that is effective in HIV-infected patients. A vaccine is not given in this study, but just investigating the adjuvant, Poly-ICLC, to determine whether it may be safe and useful in future vaccines that could be used to treat HIV, called therapeutic vaccines. One goal of future therapeutic vaccines is to reduce the virus that remains persistently inside of cells in a dormant or resting state despite treatment with HIV medications. This persistent pool is termed the "latent virus pool" or "viral reservoir". One tactic to reduce this viral reservoir is to first stimulate HIV to start replicating in order to force it out of hiding. Once viral replication occurs, the infected cells may then be recognized and killed by cells of the immune system. Therefore, we also want to see what effect Poly-ICLC has on the virus that lives inside of cells. Specifically, the investigators want to look at whether Poly-ICLC increases the level of virus inside your cells while also improving your immune system's responses. The investigators are doing this research in hope to find new ways to treat HIV infection that may reduce exposure to medications that are called antiretrovirals. Antiretrovirals are medications used to treat HIV infection. They are very effective but have side effects and have to be taken each and every day and cannot cure HIV.
This study seeks to determine the public health impact of providing rapid HIV test kits to men who have sex with men (MSM) so they may test themselves at their convenience. The study will determine if men who receive the rapid HIV test kits report HIV testing at least three times per year. This study will be conducted in four consecutive parts. The first three parts are formative in nature to guide the development and implementation of Part 4 of the study. The research study will use two different types of rapid HIV tests. The OraQuick® In-Home HIV Test for oral fluid (FDA approved for home use) and Sure Check® HIV 1/2 Assay, currently FDA-approved for professional use and distributed in the U.S. as Clearview® Complete HIV-1/2 Rapid Test. An Investigational Device Exemption will be obtained from the FDA to allow the contractor to supply the Sure Check® HIV 1/2 Assay to study participants since it is not approved for home use.
This study will be a phase 1, open label, parallel group, three period crossover study to evaluate the effect of dolutegravir (DTG) on the steady state pharmacokinetics of metformin and on the safety and tolerability of dolutegravir and metformin. Subjects will have a screening visit within 30 days prior to the first dose of study drug, three treatment periods, and a follow up visit 7-14 days after the last dose of study drug. Eligible subjects will be assigned to one of the two treatment cohorts. Subjects will receive metformin 500 milligram (mg) after every 12 hours (q12h) for 5 days in Period 1; metformin 500 mg q12h plus dolutegravir 50 mg after every 24 hours (q24h) (Cohort 1) or 50 mg q12h (Cohort 2) for 7 days in Period 2; and metformin 500 mg q12h for 10 days in Period 3. There will be no washout periods between treatments. All doses of study drug will be taken following a meal. Safety evaluations will be collected during each period. Serial pharmacokinetic (PK) samples will be collected for metformin on the last day of each period and for dolutegravir on the last day of Period 2.
Design: Randomized clinical trial involving hospitalized HIV-1 infected children. Children will be randomized to randomized to urgent (<48 hours) versus early antiretroviral therapy (7-14 days). This trial will be unblinded. Population: Hospitalized HIV-1 infected children who are antiretroviral therapy (ART) naïve ≤ 12 years of age. Sample size: 360 children will be randomized (180 per arm). Treatment: All infants will be treated with ART according to World Health Organization (WHO) and Kenyan national guidelines. Study duration: Enrollment into the study will occur over the course of 36-48 months and each infant will be routinely followed for a maximum of 6 months. Study site: Kenyan hospitals. Primary hypothesis: HIV-1 infected children hospitalized with severe co-infection either may be unsalvageable due to too far advanced immunosuppression/co-infection or may benefit from urgent ART. Secondary hypotheses: Urgent ART during an acute infection could potentially result in increased risk of immune reconstitution inflammatory syndrome (IRIS) or drug toxicities/interactions. Specific aims: 1. To compare the 6 month all-cause mortality rate, incidence of immune reconstitution inflammatory syndrome (IRIS), and incidence of drug toxicity in HIV-1 infected children (≤ 12 years old) presenting to hospital with a serious infection randomized to urgent (<48 hours) versus early ART (7-14 days). 2. To determine co-factors for mortality, IRIS, and drug toxicity. Potential cofactors will include: baseline weight-for-age, height-for-age, weight-for-height (Z-scores), CD4, HIV-1 RNA, type of co-infection, age, rate of viral load and CD4 change following ART, immune activation markers, pathogen and HIV-1 specific immune responses. Secondary aim: To determine etiologies of IRIS and to compare immune reconstitution to HIV, TB, EBV and CMV following ART overall and in each trial arm.
The purpose of this study is to determine if there is an interaction in healthy subjects taking BMS-663068 with Darunavir/Ritonavir and/or Etravirine.
This study will evaluate two new GSK1265744 sodium salt tablet formulations and provide data for selection of one of these tablet formulations for use in Phase 3. This is a single-center, randomized, two part, open-label, crossover study in healthy adult subjects. Part A is a randomized, open-label, 3-way balanced cross-over design in 24 subjects to assess the oral bioavailability of two GSK1265744 sodium salt tablet formulations relative to the current GSK1265744 sodium salt formulation being used in the phase IIb studies under fasting conditions. Part A treatment periods will be separated by a 14 day washout. After completion of Part A, preliminary PK data will be analyzed and a decision will be made based on pre-specified criteria, as to which formulation will be used to conduct Part B. Fifteen subjects who will have participated in Part A will participate in Part B and receive the selected formulation with a moderate fat meal. All treatments will be administered as single 30 mg doses of GSK1265744. Safety evaluations and serial PK samples will be collected during each treatment period. A follow-up visit will occur 10 - 14 days after the last dose of study drug.
The objectives of this Phase I/II trial is to evaluate the safety, tolerability and immunogenicity of THV01 compared to placebo in HIV-1 infected patients on HAART (highly active antiretroviral therapies). THV01 is composed of two vaccines that derived from the HIV (human immunodeficiency virus): lentiviral vectors. They are non-replicative and not infectious. They will be injected intramuscularly, eight weeks apart. Three doses will be assessed and compared to placebo. Eligible patients must have an undetectable viral load and must be treated by HAART for more than 12 months. They will be randomly allocated to one of the study group and will receive the experimental drugs at one of the three doses or a matching placebo. Their anti-HIV treatment will be alleviated around each experimental drugs' administration to enable THV01 efficacy. HAART will be resumed one week after the second injection. 15 weeks after resumption, HAART will be interrupted. Patients will then be monitored every 2 weeks for CD4+ T cell counts and viral load as well as for thorough assessment of the elicited immune response. Stringent anti-HIV treatments resumption criteria have been implemented, based on the CD4+ T cell counts and the viral load. 38 patients were enrolled in THV01-11-01 study and received the 2 injections. A long-term follow-up of all enrolled patients will be performed for 5 years post-prime administration. This will provide additional data on the safety and the potential long-term risks/benefits associated with THV01. The final study report will be written after the last patient last visit in the long-term follow-up.
The study is a phase I/II, double-blind, placebo-controlled, randomized cross-over clinical trial of tocilizumab (TCZ) or placebo in HIV-infected subjects receiving antiretroviral therapy with suppressed viral replication and CD4+ T cell count ≥350 and ≤1,000 cells/mm3)
Substance use, particularly the compulsive behaviors associated with addiction, lead to unhealthy behaviors including non-adherence to antiretroviral therapy (ART) and treatment failure. High on the list of disorders leading to non-adherence is heroin addiction as a wide range of impulsive, high-risk behaviors accompanies it. The science of adherence would be improved by developing new methods to prevent relapse to heroin addiction, especially methods that can be used in settings that are not limited by the aims to test such a method using an implantable naltrexone formulation (IN) that is approved in Russia and blocks opioid effects for 3 months. The efficacy of the IN should be better than oral naltrexone (ON) because it does not depend on daily behavior to take a tablet and maintains a constant plasma level for months, which should result in sustained blockade, less relapse, and better ART adherence and treatment response.
The Pediatric Enhanced Surveillance Study is a three part study of HIV-infected infants and children in South Africa to examine, clinical, immunologic, virologic, metabolic, psychosocial and behavioral outcomes. This study has two parts: (1) comprehensive de-identified records review of all HIV-infected children enrolled in at the pediatric Wellness and ART clinics at the five study sites; and (2) a prospective cohort surveillance study with active consented enrollment with 12-24 months of follow-up. As part of the prospective cohort, the study will aim to collect outcomes on children lost to follow-up, including causes of death through review of death certificates in the clinical chart and through verbal autopsy reports. The study will provide insights into overall outcomes for the larger pediatric patient populations in the province and South Africa. This work is designed in collaboration with the provincial health authorities of the Eastern Cape Department of Health (EC), The International Center for acquired immune deficiency syndrome (AIDS) Care and Treatment Programs (ICAP) South Africa and Center of Disease Control (CDC)-South Africa in support of the South African National ART Program for Children and aims to collect and analyze accurate, relevant and useful information that will be available on children seen at facilities. For the prospective cohort study, we will aim to enroll 400 children newly initiated on ART at 5 health facilities in the Eastern Cape of South Africa who will be actively followed for up to 24 months.
