Active clinical trials for "HIV Infections"

HIV-infected pregnant women who begin taking antiretroviral (ARV) medications in the late stages of pregnancy need an effective medication regimen to reduce the risk of transmitting HIV to their children. This study examined the virologic response, safety, and tolerability of two different ARV medication regimens in HIV-infected pregnant women who were between 20 and 36 weeks pregnant when they entered the study.

The proposed study aims to test the feasibility and preliminary efficacy of a combined 4-session HIV sexual risk reduction (HIVSRR) and microfinance intervention (including 34 training session and matched savings) to reduce unprotected sex and to increase proportion of income from sex work among women engaged in high risk sexual activity in Ulaanbaatar, Mongolia. Feasibility and preliminary efficacy will be tested using a randomized clinical trial (RCT) with 134 women sex workers meeting eligibility criteria. Following eligibility screening, eligible women will complete informed consent, a baseline assessment, and be randomized to one of 2 study conditions: 1) the combination HIV sexual risk reduction plus microfinance (HIVSRR+MF); or 2) a 4-session HIVSRR alone control condition. The study design will permit us to: Examine and enhance the feasibility (i.e. recruitment, engagement, attendance, retention data collection) of a combination HIV sexual risk reduction and MF intervention with high risk women in Ulaanbaatar, Mongolia; Examine the preliminary outcomes of the interventions on decreasing unprotected acts of vaginal and anal intercourse; increasing the proportion of protected vaginal and/or anal acts using barrier protection and decreasing number of sexual partners with repeated measures at baseline, immediately post-intervention, and 3 and 6 month follow-up assessments. Use the results of the pilot study to inform the design of a future R01 application.

The purpose of this study is to evaluate the safety of two HIV vaccines in HIV-1-infected young adults who are taking anti-HIV medications and have very low virus levels. This study will also look at how the immune system responds to the vaccines.

A proof of concept study to evaluate the feasibility of using the Shang Ring, a novel male circumcision device across all childhood age groups namely infants (under 1), 1-5 age group, 6-12 age group and the 13-17 age group. The study will evaluate the safety, efficacy and course of wound healing when using the Shang Ring technique across the four childhood age groups.

Background: - VRC01 is a manmade antibody directed against the human immunodeficiency virus (HIV). Antibodies fight infection. Researchers eventually want to know if VRC01 helps prevent or treat HIV infection. In this study they want to know if the study drug is safe if taken in a vein or under the skin. Taking VRC01 in this study will not protect against HIV infection. Objectives: - To see if VRC01 and placebo are safe and well tolerated. Eligibility: - Healthy adults 18 to 50 years old. Design: Participants will be screened with medical history, physical exam, and lab tests. Participants will be randomly divided into 4 groups. VRC01 or the placebo will be given in weeks 1 and 4. Blood samples will be taken several times after each VRC01 or placebo dose. Three groups will receive VRC01 by needle into a vein with an IV pump. It will take about 1 hour and it is done in the hospital. One group will receive either VRC01 or the placebo by needle into the fatty tissue under the skin, usually the belly. It will take up to 20 minutes and it is done in the hospital. Participants will stay in the hospital overnight after receiving the medication and have about 14 clinic visits over 4 months. Most clinic visits last about 2 hours. Participants will keep a symptom diary after receiving the medicatino. Participants can volunteer to have mouth, rectal, and genital samples taken throughout the study. The study will last 8 months.

This study will evaluate the safety of the dapivirine vaginal ring when inserts once every 4 weeks in postmenopausal women over 12 weeks of product use.

The primary objective of the study is to evaluate the capacity of Dolutegravir + Rilpivirine vs. continued triple combination HAART to maintain plasma HIV RNA ≤ 50 copies/ml throughout 24 weeks in patients with plasma HIV RNA ≤ 50 copies/mL for at least 2 years under conventional HAART (2 NNRTI + 3rd agent). The main secondary objectives are the following: % of virologic success (plasma viral load ≤ 50 copies/mL) at W24 and W48 % of patients who maintain a plasma viral load ≤ 50 copies / ml from D0 to W48 % of virological failure defined by two consecutive plasma viral load > 50 copies/mL Profile of genotypic resistance in case of virological failure. The trial will be conducted according to the design below, in 3 steps: Step 1: enrollment of 80 patients (40 in each arm) Step 2: enrollment on hold until W16 data from the 40 patients enrolled in the intervention arm have been analyzed. Step 3: resumption and completion of enrollment if conditions for resuming enrollment at the end of step 2 are fulfilled, i.e. if the percentage of patients randomized to the intervention arm who have a plasma viral load ≤ 50 copies/mL from D0 to W16 is significantly > 70%, which translates in a maximum of 6 virologic failures.

This study aims to describe the proportion of participants with non-occupational post-exposure prophylaxis (NPEP) failure, defined as NPEP non-completion (including loss to follow-up) at week 4 or primary HIV infection at week 4 or 12, excluding those participants who should and do cease study drug because: The participant is found to be HIV-infected (study drugs will be ceased until the genotype of the infecting strain is determined) The source is found to be HIV-uninfected The primary study objectives are: To describe on-drug adherence and regimen completion rates of 28 days of NPEP using dolutegravir (DTG) with co-formulated emtricitabine-tenofovir (FTC-TDF) To describe the safety of 28 days of non-occupational post-exposure prophylaxis (NPEP) using dolutegravir with co-formulated emtricitabine-tenofovir The study is a multi-site, prospective, open-label, non-randomized trial. One-hundred (100) eligible participants will receive dolutegravir (one tablet) with co-formulated emtricitabine-tenofovir, two tablets, once daily for 28 days based on one of the following exposures: receptive anal intercourse with a source known to be HIV-infected; or receptive anal intercourse with a source of unknown HIV status; or insertive anal intercourse with a source known to be HIV-infected There will be 7 study visits over a 12-week period. Follow-up post NPEP is for 8 weeks i.e. to week-12 post-exposure. Any participant who is intolerant of dolutegravir will be managed at the investigator's discretion.

Building upon the successful qualitative Phase I of the study, Phase II commences in month 10. The Project manager and research staff will recruit 600 women living with AIDS (WLA) and their oldest child between the ages of 3 and 8. The WLA will be recruited from Primary Health Centers (PHCs) randomly selected from 72 closest PHCs in terms of HIV prevalence in the rural Andhra Pradesh (AP) area of Nellore. WLA will be recruited by means of approved flyers posted in selected PHCs. Interested WLA will approach the research staff, stationed at the PHC to be screened for eligibility via a consent script. Once eligibility is determined for the WLA, based upon the following criteria: age, HIV and ART status (validated by ART and HIV card); having a child (3-8 years) and whether or not the WLA was a participant of the previous intervention group from the Asha pilot study, a parental consent will be obtained from the WLA for permission to include her oldest child in the study. The oldest child between 3-8 years of age will be brought in to the research office or PHC (after mother speaks with the child at home). All children will have blood work drawn and physical health assessment on their first visit (total of 15 minutes). All eligible WLA will undergo a second consent for enrollment. General Procedure: Following informed consent, the WLA will be randomly assigned into one of four programs 1) Asha Support Only; 2) Asha Support + Training; 3) Asha Support + Food; or 4) Asha Support + Training + Food. After blood draw and physical assessment of the WLA, an appointment will be made for the assigned interviewer (blinded to program) to visit the WLA at their home preferably (or other location of choice) to conduct several 24 hour dietary assessments. Urine will be collected in labeled bottles on the morning after the 3rd day of the diet recall by the interviewer and sent directly to the lab in a cooler. Also, on the same day, the baseline assessment will be entered into the PC tablets; 50 minutes estimated with breaks). After a longer break, the WLA will then be asked to respond to additional questions about the sociodemographic and psychomotor development of their child (about 30 minutes). Interviewers will visit the WLA monthly until the end of the intervention (month 6) to provide individual weekly Asha Support and conduct group sessions and collect ongoing data, 24-hour recall, and ART pill count for WLA, and follow up questionnaires at 6-, 12- and 18-months.

To determine the efficacy of an improved rapid diagnostic test using venous whole blood and fingerstick whole blood. The clinical performance of Reveal G4 Rapid HIV-1 Antibody Test will be determined by comparing the results with patient infected status for HIV-1 (human immunodeficiency virus type 1). The study will consist of a single one-hour visit, at which time blood samples will be collected and tested with the investigational device (Reveal G4) and FDA approved comparator assays for detection of HIV-1 antibodies.
