NCT02128217
Early identification of acute HCV infection is essential to prevent chronic infections and the long-term liver disease complications that may occur. Early identification and treatment of HCV during the acute phase can result in significantly higher response rates with shorter durations of therapy. Pegylated-interferon alfa (PEG-IFN) was the typical treatment for HCV infection. Participants subcutaneously inject PEG-IFN where the average duration of treatment was approximately 20 weeks. With the advancement of direct-acting antivirals (DAAs), it was possible to see if a new DAA might be non-inferior compared to (PEG-IFN). The study was designed to see if a fixed-dose combination tablet can replace the old HCV treatments by being more effective, safer and better tolerated in HIV-infected participants with new HCV infection. The study was a Phase I, open-label, two cohort clinical trial, in which 44 acutely HCV-infected HIV-1 positive participants were enrolled. Participants in each cohort were evaluated in two steps: on treatment (Step 1) and follow-up after discontinuing study treatment (Step 2). The cohorts were enrolled sequentially. Participants in Cohort 1 were enrolled and administered oral Sofosbuvir (SOF) in combination with weight-based ribavirin (RBV). Participants in Cohort 2 were enrolled and administered an oral fixed dose combination of Ledipasvir/Sofosbuvir (LDV/SOF).
NCT00094523
This study was designed to evaluate and compare safety, tolerability of subjects who successfully suppress HIV-1 on their first PI regimen to those who switch to fosamprenavir. This is a 48-week study, where subjects who were assigned to be in their original PI-group have the option of switching to fosamprenavir on week 24. Prior to being assigned their treatment group, subjects had to be suppressed for at least three months. All subjects also take a background regimen of two nucleoside/nucleotide reverse transcriptase inhibitors.
NCT01263015
The purpose of this trial is to assess the non-inferior antiviral activity of GSK1349572 50 mg plus Abacavir/Lamivudine once daily versus Efavirenz/Emtricitabine/Tenofovir disoproxil fumarate (ATRIPLA® a trade mark of Bristol-Myers Squibb and Gilead Sciences LLC) over 48 weeks; non-inferiority will also be tested at Week 96. This study will be conducted in HIV-1 infected ART-naïve adult subjects. Long term antiviral activity, tolerability, safety, and development of viral resistance will be evaluated.
NCT01772823
Approximately 200 HIV-uninfected young men who have sex with men (YMSM) at high risk of acquiring HIV infection, ages 18-22 years, inclusive, will be recruited across all participating Adolescent Medicine Trials Units (AMTU). The behavioral intervention will be assigned at the level of the site, which include Many Men, Many Voices (3MV) and Personalized Cognitive Counseling (PCC). Subjects will first complete the behavioral intervention offered at their respective site and then be provided with open label emtricitabine (FTC)/tenofovir (TDF) (Truvada®) as PrEP. Behavioral and biomedical data will be collected at baseline and 0, 4, 8, 12, 24, 36 and 48 weeks. Any subjects who become HIV infected during the course of the study will be discontinued from the study agent and followed for an additional 24 weeks after the study visit at which HIV infection is confirmed. Those subjects who meet specific bone or renal criteria at the Week 48 visit or the 24-Week HIV Seropositive visit will be followed for an additional 48 weeks in the Extension Phase to monitor longer-term outcomes of potential concerns.
NCT01751594
The proposed research study aims to conduct a culturally-based secondary prevention intervention targeted toward HIV-positive Black young men who have sex with men (B-YMSM) to explore (1) feasibility and acceptability (Trial 1 and Trial 2) and (2) evidence of potential efficacy (Trial 2). The primary outcomes will be health promotion behaviors (i.e., treatment adherence, sexual risk reduction, reduction in substance use behaviors, and HIV status disclosure). Psychosocial factors (i.e. self-esteem, critical consciousness, and socio-political awareness) will be examined as secondary outcomes.
NCT00855335
The purpose of this study is to study how changes in the body during pregnancy influence the blood levels of TMC114 (darunavir) and ritonavir taken together, darunavir and cobicistat taken as a fixed-dose combination, TMC125 (etravirine) taken alone or with darunavir and ritonavir or rilpivirine in patients with human immunodeficiency virus-1 (HIV-1). This study will examine how these drugs are absorbed in the body, how they are distributed within the body and how they are removed from the body over time. Any pregnant woman who is currently receiving darunavir with ritonavir, darunavir with cobicistat, etravirine or rilpivirine for HIV-1, and who meets the eligibility criteria for the study, will be allowed to enroll. Patients must be willing to remain on study medication during the course of their pregnancy, and 12 weeks postpartum. The information collected may help answer questions about how to best prescribe these three drugs for pregnant women.
NCT00118898
Currently, the preferred anti-HIV regimens used in the United States consist of two nucleoside reverse transcriptase inhibitors (NRTIs) and the nonnucleoside reverse transcriptase inhibitor (NNRTI) efavirenz (EFV). However, with new anti-HIV drugs being approved, alternative regimens need to be tested to determine if new drug combinations have increased effectiveness in treating HIV. The purpose of this study is to test the safety, tolerability, and effectiveness of four different regimens in HIV-infected adults who have never taken anti-HIV drugs.
NCT00084136
This study compared 3 different three-drug combinations in HIV infected individuals starting their first HIV treatment regimens. Participants were recruited from resource-limited areas in Africa, Asia, South America, Haiti, and also from the United States. The study hypothesis was each of the once daily combinations (PI based, or NNRTI based) would not have inferior efficacy compared to the twice daily NNRTI based combination.
NCT00082628
The primary objective of the study is to determine if Serostim® 4 mg administered daily for 12 weeks as treatment for the abnormal fat accumulation and distribution associated with HIV-associated Adipose Redistribution Syndrome (HARS) reduces Visceral Adipose Tissue (VAT, measured by CT scan) more effectively than placebo.
NCT02480881
This is an open-label, single sequence, 4-cycle, 4-treatment, drug-drug interaction (DDI) study in healthy female subjects on oral contraceptives (OC). There is no formal research hypothesis to be statistically tested. It is expected that coadministration of BMS-663068 with OC will not affect the pharmacokinetics (PK) of either ethinyl estradiol (EE) or norethindrone (NE).
NCT01449929
This study will be conducted in approximately 468 HIV-1 infected antiretroviral therapy (ART)-naïve subjects. Subjects will be randomized 1:1 to receive dolutegravir (DTG) 50 mg once daily (approximately 234 subjects) or darunavir/ritonavir (DRV/r) 800 mg/100 mg once daily (approximately 234 subjects), each in combination with fixed-dose dual nucleoside reverse transriptase inhibitor (NRTI) therapy (either abacavir/lamivudine (ABC/3TC) or tenofovir/emtricitabine (TDF/FTC). Subjects will be stratified by screening HIV-1 RNA and background NRTI selection. The primary analysis will take place after the last subject completes 48 weeks on therapy; an additional analysis will be conducted after the last subject completes Week 96 on study.
NCT01092611
The purpose of this long-term follow-up study is to assess the long-term health status of HIV-infected subjects who previously participated in GSK-sponsored trials evaluating the investigational HIV vaccine 732462. This study will provide additional data concerning the long-term benefits/risks associated with vaccination. No vaccine will be administered during the study period. Vaccines were administered during the primary studies.
NCT00951015
This Phase IIb study in HIV-infected antiretroviral naive subjects will select an optimal once daily dose of GSK1349572 from a range of doses for future evaluation.
NCT00931801
The purpose of this Phase IV pilot study is to evaluate the safety, tolerability, and satisfaction of a nucleoside analog reverse-transcriptase inhibitors (NRTI)sparing regimen for participants fully suppressed on an atazanavir/ritonavir based highly active antiretroviral therapy (HAART)regimen plus emtricitabine/tenofovir (Truvada). Several pharmacologic factors support this concept including the favorable drug interaction between atazanavir and raltegravir. Participants will be randomized to either continue on their current regimen or one of two study arms (atazanavir 300mg plus ritonavir 100mg daily plus raltegravir 400mg twice daily or atazanavir 300mg twice daily plus raltegravir 400mg twice daily). Participants will be followed for 48 weeks for safety, tolerability, and satisfaction. After baseline, the participants will have six clinic visits for evaluation and labs.
NCT02415595
The purpose of this study is to find at least one dose of BMS-955176 that will be safe, effective and tolerable for HIV-1 infected treatment naive adults.
NCT01721109
The primary objectives of this study are to evaluate the steady-state pharmacokinetics (PK) and confirm the dose of the elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF) single-tablet regimen (STR) (Part A) and to evaluate the safety and tolerability of EVG/COBI/FTC/TDF STR through Week 48 (Part B) in HIV-1 infected, antiretroviral (ARV) treatment-naive adolescents. A total of 50 adolescent participants (12 to \< 18 years of age) will be enrolled to receive EVG/COBI/FTC/TDF as follows: * Part A: Twelve to 16 eligible participants will be enrolled to evaluate steady-state PK, and confirm the dose, with the intent to enroll at least 4 participants 12 to \< 15 and at least 4 participants 15 to \< 18 years of age. * Part B: Following confirmation of EVG exposure in at least 12 participants from Part A, 34 to 38 participants in addition to those enrolled in Part A will be enrolled to evaluate the safety, tolerability, and antiviral activity of EVG/COBI/FTC/TDF STR.
NCT01923311
The primary objectives of this study are to evaluate the safety, tolerability and steady-state PK and confirm the dose of EVG/r in HIV-1 infected, antiretroviral treatment-experienced children 4 weeks to \<18 years of age. The study consists of 2 parts: Part A and Part B. Part A will enroll participants with suppressed viremia (HIV-1 RNA \< 50 copies/mL) or failing a current antiretroviral (ARV) regimen (HIV-1 RNA \> 1,000 copies/mL only for participants in Cohort 2, Part A) to evaluate the steady state PK and confirm the dose of EVG. Part B will enroll participants who are failing a current ARV regimen (HIV-1 RNA \> 1,000 copies/mL) to evaluate the safety, tolerability, and antiviral activity of EVG. The study consists of 4 age cohorts with each cohort including 2 parts (Part A and Part B) with the exception of the adolescent age cohort (Cohort 1: 12 to \< 18 years old) containing Part B only.
NCT01543958
HIV-infected people can have an increase in inflammation in their body organs, even after taking anti-HIV medicines. Sevelamer carbonate is used to bind phosphate in dialysis patients. It can also bind endotoxin in the gut and lowers endotoxin levels in the blood of dialysis patients. Sevelamer carbonate decreases the inflammation endotoxin causes in dialysis patients. A5296 is a phase II, single-arm study to evaluate the effect of 8 weeks of sevelamer carbonate administration on markers of microbial translocation and T-cell activation in the blood in chronically HIV-infected subjects not receiving ART.
NCT01335698
The purpose of this study is to describe the safety, efficacy, and pharmacokinetics of a regimen of atazanavir powder boosted with ritonavir and an optimized dual nucleoside reverse transcriptase inhibitor in pediatric patients aged ≥3 months to \<11 years.
NCT00860977
This study is a multicentre, randomized, placebo-controlled, fully blinded, clinical trial of twice daily oral valacyclovir 500mg versus placebo with the goal of delaying the need for initiating HAART among HIV infected individuals who neither use nor require HAART, and who have not used chronic suppressive anti-HSV therapy for at least the 6 months prior to study initiation.
