A multicenter, randomized, parallel-group, placebo-controlled, double-blind, Phase 1/2a clinical study to investigate the safety, tolerability, immunogenicity and exploratory efficacy of a vaccine regimen consisting of an Ad26.Mos4.HIV prime and a boost with Modified Vaccinia Ankara (MVA)-BN-HIV in combination with broadly neutralizing antibodies (bNAb) PGT121, PGDM1400, and VRC07-523LS in human immunodeficiency virus type 1 (HIV-1)-infected study participants on suppressive anti-retroviral therapy (ART).
The purpose of this study is to demonstrate the effectiveness of Symtuza® in a rapid reinitiation model of care in patients with HIV-1 infection and who are treatment-experienced but have been off of antiretroviral therapy (ART) for 12 or more weeks.
This study is intended to evaluate: 1. Any changes in the gut microbiome from baseline compared to end of study in both healthy (HIV-negative) subjects and HIV+ patients with or without chronic diarrhea, following one month of treatment with crofelemer (Mytesi), delayed release 125 mg tablets twice daily (BID) following one month of treatment. 2. The safety and tolerability of crofelemer, (Mytesi) delayed release 125 mg tablets BID in healthy (HIV-negative) volunteers and HIV+ patients following one month of treatment.
While advances in medication have led to greatly improved outcomes for people living with HIV/AIDS, less than one-third of all people living with the disease are adherent enough to their medication to achieve viral suppression. Alcohol consumption has been shown to have a significant effect on HIV medication adherence, so the proposed research will aim to reduce alcohol use among people living with HIV/AIDS through a technology-driven intervention. This eight-session intervention will be delivered using a combination of videoconferencing, smart phones, and Bluetooth-enabled breathalyzers for monitoring of alcohol consumption, with an overall goal of reducing alcohol use, mitigating adherence issues, and achieving optimal prevention and treatment responses for people living with HIV/AIDS.
STRIDE2 is a longitudinal, non-randomized study of individuals living with HIV who are dependent on opioids. This study is funded by the National Institute on Drug Abuse (R01DA030768, Altice, PI; Taxman \& Lawson, Co-PIs) and is being conducted by George Mason University, Yale University, and Howard University.
The purpose of this study is to test the effectiveness and implementation of a brief, integrated behavioral intervention for HIV medication adherence and substance use in the HIV care setting in South Africa. The intervention is specifically designed to be implemented by non-specialist counselors using a task sharing model in local HIV clinics. The behavioral intervention will be compared to usual care, enhanced with referral to a local outpatient substance use treatment program (Enhanced Standard of Care - ESOC) on study endpoints (as described in study endpoint section below).
The purpose of this study is to use technology to improve symptom status and ultimately improve patient centered outcomes in people living with HIV/AIDS (PLWHA). The primary purpose of the intervention (VIP-HANA) is to improve symptom status. The investigators hypothesize that VIP-HANA will improve symptom frequency and intensity.
The intent of the proposed randomized controlled trial is to test the efficacy of a principle-based, transdiagnostic cognitive behavioral therapy (CBT) intervention that addresses the pathways through which minority stress compromises young gay and bisexual men's (YGBM) co-occurring mental (e.g., depression), behavioral (e.g., substance use), and sexual (e.g., condomless anal sex) health problems.
The purpose of the study is to evaluate the safety and feasibility of administering SB-728mR-HSPC after conditioning with busulfan.
The purpose of this study is to determine whether the use of rectal lubricants can affect how well the medication, Truvada, will work to prevent infection with HIV when someone is exposed to HIV in the rectum.
The purpose of this study is to determine whether cognitive rehabilitation or psychoeducation impacts medication adherence in HIV-1 seropositive individuals.
This study is designed to see how HIV infected patients perform when taking a single fixed dose HIV medication compared to a regimen with multiple tablets. The study is also going to be looking at the differences in complications between the two groups.
The purpose of this study is to assess the safety and tolerability of various regimens containing adenovirus serotype 26-Mosaic -Human Immunodeficiency Virus (Ad26.Mos.HIV), Modified Vaccinia Ankara (MVA)-Mosaic, and/or HIV type 1 Clade C glycoprotein 140 drug product (gp140 DP) components and to compare envelope binding antibody responses between the different vaccine regimens.

The purpose of the study are the following: 1) Pilot test and conduct baseline and 3 month follow up assessments to evaluate the preliminary efficacy of the DVD-based HIV/HCV intervention by randomly assigning 210 Latino corrections-involved, outpatient abuse treatment clients to either the experimental intervention or to a wait list control group; and 2) to evaluate both participant and interventionist acceptability of this novel DVD-based intervention. They study hypothesis are the following: 1. participants in the intervention condition will report greater reductions in sexual risk behaviors (e.g., unprotected sexual contact) from baseline to 3 month follow-up compared to the control group; 2. participants will report greater reductions in drug risk behaviors (e.g., sharing injection equipment, drug use during sex) from baseline to 3 month follow-up compared to the control group; 3. participants who report more HIV prevention information, motivation, and behavioral skills will report fewer sexual risk behaviors.
Background: - The human immunodeficiency virus (HIV) causes acquired immune deficiency syndrome (AIDS). Combination antiretroviral therapy (ART) drugs treat HIV infection. They generally decrease the amount of HIV virus in the blood (called viral load) to very low levels. This happens only if the drugs still fight HIV and if taken every day exactly as prescribed. When not taken as directed, or if the ART drugs are not strong enough, the virus can become resistant to them, and the ART will not work to control the virus. Researchers want to know how to control HIV in people who can t lower their viral load with their current ART drugs. Objective: -\<TAB\>To better control HIV in people who can t get a lower viral load even with ART drugs and to learn more about why the HIV is not under control. Eligibility: * People at least 18 years old and with HIV. * People who have been on at least two combinations of ART drugs (including current ART). * People whose last two viral loads were greater than 1,000 copies/mL. Design: * Participants will be screened with medical history, physical exam, and blood tests. * Participants will then have a baseline visit. They will have another physical exam, blood tests, plus answer questions about what they know about HIV and ART, and how they take their ART. * Participants will arrange to stay in the NIH hospital for 7 8 days. * They will take their medications as usual. At the time to take the ART drugs, they will have to ask a nurse to bring them. If they forget, the nurse will bring them. * Participants will meet with a doctor, pharmacist, social worker and nurse to discuss ways to help participants remember to take their drugs. * Participants will have blood drawn about every other day. * Researchers will study the test results. Some participants will be put on different ART drugs. If that happens, participants will have another NIH hospital stay for 7-8 days. * Participants will have 4 follow-up visits over 12 weeks, then every 3 months for 2 years or more.
The primary objective of this study is to evaluate the efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed dose combination (FDC) plus darunavir (DRV) relative to current antiretroviral regimens (ARV) in virologically suppressed, HIV-1 positive participants with HIV-1 RNA \<50 copies/mL at Week 24. This study consists of 48 weeks of open-label phase followed by an optional Extension Phase in which all the participants will receive E/C/F/TAF+DRV.
The primary objective of this study is to evaluate the efficacy of tenofovir alafenamide (TAF) versus placebo, each administered with the existing, failing antiretroviral (ARV) regimen. There are 2 parts to this study: Part 1 and Part 2. Part 1 consists of 2 cohorts, starting with a sentinel cohort, in which participants will be enrolled to receive open-label TAF in addition to their current failing ARV regimen. This cohort will then be followed by a randomized, double-blind, cohort to compare the addition of TAF or placebo in HIV-1 positive adults who are failing their current ARV regimen. In Part 2, all participants who complete Part 1 of the study will discontinue their failing ARV regimen and TAF or placebo for a 14-day washout period. Following the washout period, all participants who received TAF in Part 1 and have a \> 0.5 log10 decline in HIV-1 RNA will receive elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) single-tablet regimen (STR) plus atazanavir (ATV) once daily for 48 weeks. Participants who received TAF who have a ≤ 0.5 log10 decline in HIV-1 RNA will be discontinued from the study and will not be eligible to continue into Part 2 of the study. All participants who received placebo in Part 1 will be eligible to participate in Part 2 regardless of their viral load change. After completion of Part 2, all participants will be eligible to continue to receive E/C/F/TAF plus ATV in the extension phase until E/C/F/TAF becomes commercially available, or until Gilead Sciences terminates development of E/C/F/TAF in the applicable country.
The primary objective of this project is to assess the study population's acceptance of two medication adherence support strategies: incentive-based programs and electronic medication monitoring. The study population is adolescents (ages 16 - 24) positive for human immunodeficiency virus (HIV) currently undergoing treatment with antiretrovirals at St. Jude's HIV clinic. Participation in the study will involve completion of a survey: an Audio Computer Assisted Self Interview (ACASI). The duration of the survey is anticipated to be 10-20 minutes. Patient identifiers will not be attached the survey.
The purpose of this project is to gather pilot data related to risk factors associated with suicide in Veterans with Human Immunodeficiency Virus (HIV)/ Acquired Immune Deficiency Syndrome (AIDS) and to develop an educational and interventional tool and instructional guide that can be utilized by local and national providers to increase understanding regarding suicide risk assessment. There are no hypotheses associated with this qualitative pilot study.
The primary objective of this study is to evaluate the efficacy of a regimen containing elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) in HIV-1 infected, antiretroviral treatment-naive adult women.
This randomized clinical trial uses a health plan's electronic medical record (EMR) alcohol screen; and examines innovative behavioral interventions, and their cost effectiveness, for hazardous drinking within a large HIV primary care clinic. We will compare Motivational Interviewing (MI) and Email Feedback (EF) to usual care; and evaluate the effect of the interventions on unhealthy drinking, comorbid drug use, enrollment in substance use treatment programs, and HIV outcomes including antiretroviral therapy adherence, HIV RNA control, and unsafe sex. Given the well-known adverse effects of unhealthy drinking on HIV care and outcomes, the proposed study has the potential to make a significant impact in the care of HIV patients.
