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.
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.
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.
NCT00325702
This project will develop, implement, and evaluate a community-level intervention for Black and White substance-using MSM between the ages of 15 and 29. The intervention is designed to change both social norms and risk behavior using persuasive media communication and interpersonal networking as primary intervention strategies. Qualitative data from focus groups and interviews will inform the development of the intervention. The effects of the intervention will be assessed through annual interviews with young Black and White MSM in Philadelphia where the intervention will be implemented and in Baltimore, our comparison community.
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.
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.
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).
NCT01347164
Black men who have sex with men (MSM) have the highest rates of HIV infection in the United States and represent a population in need of new HIV prevention interventions. Although 20 to 40% of Black MSM are estimated to have female partners, no interventions tailored to the needs of Black MSM/W have been developed and rigorously evaluated. This project will develop, implement, and evaluate an individual-level intervention (ILI), titled "RISE", that will assist Black MSM/W to reduce their risk for acquiring and transmitting HIV infection. This intervention will address the effect of individual level factors, interpersonal relationships including sexual, peer and family relationships, and socio-cultural influences on the sexual risk behaviors of MSM/W. The intervention will consist of six counseling sessions held between a trained counselor and participant, and will be guided by three theoretical perspectives: an ecological perspective of behavior, stress and coping theory, and social cognitive theory. The COLOURS Organization, the sole agency in Philadelphia dedicated to exclusively serving the Black LGBT community, will be a key collaborator in the development and implementation of the intervention. The evaluation design utilizes a randomized controlled trial to test the effectiveness of the proposed intervention. Chain referral, based on principles of respondent-driven sampling, will be used to recruit 250 HIV-positive and HIV-negative Black bisexually-active men into this study. The specific aims of this research are to: * develop a new theoretically-based individual-level HIV prevention intervention culturally tailored to the needs of HIV-positive and HIV-negative Black MSM/W; * evaluate the intervention with a randomized control group design, using RDS to recruit 250 Black MSM/W who do not inject drugs and who report recent unprotected sex; * assess the efficacy of the intervention and test the intervention model through the collection of behavioral risk assessments and HIV and STD testing at three time points: baseline, immediately post-intervention and three-months post-intervention; * examine and describe individual factors, interpersonal relationships and network factors, and socio-cultural factors that may affect risk behaviors for HIV infection and transmission among Black MSM/W; * develop recommendations for recruiting Black bisexually-active men and providing them with targeted HIV prevention interventions. Evaluation data collection will be conducted using ACASI. Data analysis will include Repeated Measures ANOVA to make assessments of changes over time and intervention dose effects and structural equation modeling to assess causal associations between factors in the conceptual model. This proposed study has significance for increasing our understanding various types of factors that may affect sexual risk behaviors of Black MSM/W as well as potentially providing an important new tool for HIV prevention specifically targeting the needs and risk behaviors of Black MSM/W.
NCT02227277
The purpose of this study is to determine if treatment with pegylated interferon alpha 2b (peg-IFN-α2b) will reduce the amount of integrated HIV DNA in peripheral blood cells and tissues of individuals with chronic HIV infection receiving antiretroviral treatment (ART). A reduction and/or clearance of the latent viral reservoir (i.e.: virus that remains dormant in HIV-infected subjects receiving suppressive treatment ) is considered essential for HIV eradication. By measuring the changes in integrated proviral HIV DNA, which is considered a surrogate measure of the latent reservoir, the investigators will establish if peg-IFN-α2b treatment should be considered as a component of future viral eradication strategies.
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.
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.
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.
NCT01579695
The purpose of this observational, 10-year, prospective cohort study is to assess the potential safety concerns of long-term exposure to EGRIFTA® in HIV-infected subjects with abdominal lipohypertrophy compared with a similar group of subjects not exposed to EGRIFTA®.
NCT00665353
Insulin resistance is common in people coinfected with HIV and Hepatitis C virus (HCV) and is associated with poor responses to treatment for HCV. Pioglitazone is an FDA-approved medication for the treatment of type 2 diabetes. It works by increasing the body's sensitivity to insulin. The purpose of this study is to determine whether treatment with pioglitazone prior to HCV treatment with peginterferon and ribavirin is safe and effective in improving the treatment outcome in insulin-resistant, HIV/HCV-coinfected people for whom previous treatment with peginterferon and ribavirin was unsuccessful.
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.
NCT02043015
The purpose of this study is to evaluate the acceptability and uptake of a combination package of biomedical, behavioral and community-level HIV prevention interventions and services for men who have sex with men (MSM) in South Africa.
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.
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.
