Filter by: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 purpose of this study is to evaluate the efficacy and tolerability of DAA-based regimens in the clinical practice in HIV/HCV-coinfected patients. Hypothesis: The efficacy and tolerability of DAA-based regimens in the clinical practice is different to what is observed in clinical trials in HIV/HCV-coinfected patients.
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.
This study identifies social and behavioral factors likely to influence PrEP acceptability and adherence among men who have sex with men (MSM), and collaborates with a community health center to evaluate a two-stage intervention to improve PrEP decision-making, as well as persistence and adherence for those who chose to take PrEP.
Ibalizumab is a humanized immunoglobulin G monoclonal antibody directed against a human T-cell receptor (CD4) and thus suppresses HIV replication by blocking entry of HIV into CD4+ lymphocytes. Ibalizumab has completed phase I and II clinical studies in HIV-negative and HIV-infected individuals showing safety and efficacy for suppressing HIV replication.
The two original objectives were to determine in HIV-infected children initiating antiretroviral therapy (ART): 1. Whether clinically driven monitoring (CDM) will have a similar outcome in terms of disease progression or death as routine laboratory and clinical monitoring (LCM) for toxicity (haematology/biochemistry) and efficacy (CD4)? 2. Whether induction with four drugs from two ART classes followed by maintenance with three drugs after 36 weeks be more effective than a continuous non-nucleoside reverse transcriptase inhibitors (NNRTI)-based triple drug regimen in terms of CD4 and clinical outcome? Two secondary objectives were to determine 3. Whether changing from twice daily lamivudine+abacavir to once daily lamivudine+abacavir after 48 weeks on ART will have a similar outcome in terms of virological suppression and will result in improvements in adherence to ART? 4. Whether stopping daily cotrimoxazole prophylaxis in children over 3 years of age who have been on ART for at least 96 weeks has a similar outcome in terms of hospitalisation or death as continuing daily cotrimoxazole?
