NCT00082394
The aim of this study was to assess whether TRIZIVIR, administered twice-daily was as safe, tolerable and efficacious as a combination of the drugs COMBIVIR administered twice-daily and atazanavir administered once daily. Over the course of 48 weeks, various parameters that measure safety, tolerability and efficacy of the investigational drugs were measured and compared.
NCT00002377
To investigate the efficacy and safety of RS-79070 when used as induction therapy in patients with newly diagnosed peripheral retinitis. To assess the effects of induction and maintenance level dosing of RS-79070 on CMV viral load, estimated by plasma CMV PCR. To assess the pharmacokinetics of ganciclovir following administration of RS-79070 in the target population.
NCT00100984
The main objective of this study is to compare the safety and efficacy of an enfuvirtide containing regimen to a nucleoside combination regimen. Resistance information will also be collected.
NCT01003990
The purpose of this study is to provide atazanavir or tenofovir-emtricitabine to HIV-infected subjects who have completed atazanavir or tenofovir-emtricitabine therapy on a previous BMS sponsored clinical trial and to collect long-term safety information on the treated population.
NCT02257788
PRO 140 2103 is a multicenter, randomized parallel group study, conducted in male and female adult subjects infected with CCR5-tropic HIV-1.
NCT01492842
The proposed study is a substudy of ATN 106 and a cross sectional study intended to be conducted at each of the AMTUs newly participating in ATN III. The intent is to enroll all youth with behaviorally-acquired HIV who have enrolled in ATN 106. The study involves a review of the subjects' medical chart and a collection of an oral rinse sample.
NCT02411630
The purpose of this study is to test a new way to take a questionnaire that asks about adherence (whether the person is taking the medicine correctly). This new questionnaire is called Interactive Questionnaire System (iQS). In this study, the iQS will be tested on HIV-negative young men who have sex with men (YMSM) who are taking PrEP as part of another study, either ATN 110 or ATN 113.
NCT02438592
This is an observational study involving retrospective and prospective medical record review covering a total maximum of 104 weeks (24 months) per subject. An Audio Computer- Assisted Self-Interview (ACASI) at study entry will assess demographic and psychosocial variables of study subjects. Data will also be collected to assess clinic level variables. Definitions of engagement, prescription of antiretroviral therapy (ART), and viral suppression in the Continuum of Care (CoC) will utilize common definitions including those by U.S. Department of Health and Human Services (DHHS) and Health Resources and Services Administration (HRSA) HIV/AIDS Bureau (HAB). Data will be collected in a large, simple trial design manner to provide all elements for both the primary and secondary outcomes.
NCT00104429
This study is a 96-week study designed to evaluate the safety and efficacy of GW873140 in combination with Combivir in HIV infected, untreated subjects.
NCT00491556
This study proposes to evaluate a pre-DHHS guideline of HAART initiation and then de-intensification management strategy in adolescents with mild immunosuppression and compare changes in CD4% from baseline to week 48 and then during de-intensification.
NCT00106964
Hepatitis B is a contagious virus that can damage a person's liver. It can be prevented by vaccination, but for many HIV-positive people, the vaccines do not help them achieve adequate protection against this virus. In an attempt to improve response to vaccination and achieve protection from hepatitis B, this trial will compare the immune system response to 3 hepatitis B vaccine regimens in HIV-positive adolescents 12 through 24 years of age.
NCT00489034
The proposed multi-site, longitudinal study will examine the correlation of substance use, mental health disorders, and social networks to engagement in care for HIV-infected adolescent females, aged 13 years, 0 months - 23 years, 11 months, and suggest ways to promote adherence and retention in treatment, care, and prevention programs. Qualitative and quantitative data collection methods will be used with index participants and network members.
NCT00103883
Identifying young people with early HIV-1 infection is important for increasing linkage to care, for behavioral counseling, and for enrolling individuals into programs that can provide effective interventions to disease progression and improve outcome. This study will develop and evaluate a saliva-based sensitive/less sensitive (S/LS) assay for differentiating persons with recent HIV-1 infection (less than 133 days) from those with established HIV-1 infection.
NCT00142753
This is an exploratory, laboratory-based evaluation of cellular immune response to immunization with hepatitis B surface antigen in HIV-infected and HIV-uninfected adolescents. This is a substudy of ATN 024 and ATN 025. This substudy will compare cellular immune response in responders and nonresponders to immunization and also evaluate the relationship of these factors to the persistence of known correlates of serologic protection for the hepatitis B virus.
NCT00867854
This laboratory-based sub-study of ATN 061 and ATN 071 will examine the effect of early treatment followed by treatment de-intensification to atazanavir/ritonavir (ATV/r) monotherapy on steady-state frequencies of replication-competent CD4+ T cell Human Immunodeficiency Virus (HIV)-1 reservoirs or cell-associated infectivity (CAI) and persistent low-level viremia (LLV), and their contribution to successful long-term control of HIV-1 replication among HIV-1 infected adolescents and young adults.
NCT00107029
This protocol is a study of HIV+ young people who were identified as having certain HIV-1 specific T-cell responses and genetic markers while previously enrolled in the 5-year longitudinal adolescent study, "REACH." Blood samples will be collected, a medical and medication history and physical examination will be performed every 6 months for a total of 2 years.
NCT00686049
The goal of this study is to assess the reliability of the HIV Treatment Readiness Measure (HTRM) to assist clinicians in: (1) determining whether or not youth living with HIV are ready to initiate HAART and (2) identifying youth who may be in need of additional support services to facilitate their adherence to HAART. The current study will examine the psychometric properties of the HTRM and establish its test-retest reliability over a two week period. If the HTRM is found to be reliable, a subsequent study will examine its predictive validity.
NCT00142740
This laboratory-based substudy of an effectiveness trial of two Hepatitis B vaccines in HIV-negative youths is being done to evaluate the genetic contribution to the individualized immune response.
NCT00068809
This study will determine if taking anti-HIV drugs 4 days a week will control HIV-1 viral replication in patients who have already had at least 6 months of documented viral suppression with full-time treatment. If this strategy is shown to be safe in this study, a larger study will be undertaken to determine if the strategy can decrease overall drug exposure and help young people adjust more easily to a chronic medication schedule.
NCT00891644
This is the second phase of a two-phase, cross-sectional study of linkage to medical care of HIV positive youth. Social, psychological and behavioral factors associated with receipt of care will be evaluated. This study will also compare three methods for recruitment of out-of-care youth using a randomized permuted block list of possible sequences.
