NCT ID: NCT05872659 Recruiting - AIDS Virus Clinical Trials

Mesenchymal Stem Cells for Immune Non-responder Patients With HIV Infection

Start date: April 16, 2023
Phase: Early Phase 1
Study type: Interventional

The goal of this clinical trial is to explore the effect of mesenchymal stem cell therapy on immune non-responder patients. The main questions it aims to answer are: 1. Efficacy of human umbilical cord mesenchymal stem cells combined with antiviral therapy in the treatment of AIDS patients with immune non-response. 2. Safety of human umbilical cord mesenchymal stem cells combined with antiviral therapy in AIDS patients with immune non-response. Participants will receive CD4,CD4/CD8, and RNA viral load tests and will be randomly assigned to either saline or mesenchymal stem cell therapy. Investigators will evaluate the safety and efficacy of mesenchymal stem cell therapy based on examination results.

NCT ID: NCT05423418 Recruiting - Clinical trials for Human Immunodeficiency Virus (HIV)

Safety, Tolerability, and Immunogenicity of ALFQ in a HIV Vaccine Containing A244 and B.65321 in Healthy Adults

RV575
Start date: August 29, 2022
Phase: Phase 1
Study type: Interventional

This study will evaluate the safety and tolerability (including reactogenicity) of candidate vaccine A244/B.63521 with Army Liposome Formulation (ALF) mixed with the saponin QS-21(Quillaja saponaria-21) (ALFQ) adjuvant. The purpose of this phase I randomized, double-blind clinical trial is to optimize vaccine adjuvant ALFQ dosing by assessing safety, reactogenicity, and immunogenicity. Safety and tolerability will be assessed with both clinical and laboratory monitoring. Sixty human immunodeficiency virus (HIV) negative participants will be enrolled to one of three arms. Vaccinations via intramuscular (IM) injection will occur at months 0, 1, and 2. All participants will receive A244 and B.63521 (300 micrograms of each). In addition, Arm 1 will receive 200 micrograms of ALFQ. Arm 2 will receive 100 micrograms of ALFQ. Arm 3 will receive 50 micrograms of ALFQ.

NCT ID: NCT03615183 Completed - Clinical trials for Human Immunodeficiency Virus

A Study of MK-8527 in Human Immunodeficiency Type 1 Virus (HIV-1) Infected Participants (MK-8527-002)

Start date: February 11, 2019
Phase: Phase 1
Study type: Interventional

This study will evaluate the anti-retroviral activity of MK-8527 in HIV-1 infected, ART-naïve participants. The primary hypothesis is that MK-8527 has superior anti-retroviral activity compared to placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.

NCT ID: NCT01976715 Completed - Clinical trials for Human Immunodeficiency Virus

Study of People With HIV Infection Who Have High Viral Loads Despite Combination Antiretroviral Therapy

Start date: February 11, 2014
Phase:
Study type: Observational

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.

NCT ID: NCT00458302 Completed - HIV Infections Clinical Trials

Treatment Simplification by Darunavir/Ritonavir 800/100 mg Once a Day Versus a Triple Combination Therapy With Darunavir/Ritonavir

MONET
Start date: June 2007
Phase: Phase 3
Study type: Interventional

The purpose of the study is to compare the efficacy, safety and tolerability of darunavir/ritonavir 800/100 mg once a day (O.D.) as a monotherapy versus a triple combination therapy containing 2 nucleosides and darunavir/ritonavir in 250 HIV-1 infected patients who have been on Highly Active Antiretroviral Therapy (HAART) and have plasma viral load below 50 copies/ml for at least 24 weeks.

NCT ID: NCT00393302 Completed - HIV Clinical Trials

HIV Testing in Pregnant Women: Evaluating an Opt-Out Testing Strategy

Start date: September 2003
Phase:
Study type: Observational

Mother-to-child transmission of HIV is an important but preventable mode of infection. Prevention depends on identifying pregnant women infected with HIV and offering medications during pregnancy which can dramatically decrease the chances of transmission. Currently universal screening of all pregnant women for HIV is recommended in the province of Ontario. Unfortunately the rates of screening are still low: estimates place the average rate at 50% -60%. We believe that rates in our clinic at the Women's Health Care Centre are significantly higher in part because all our patients have a first obstetrical visit. This is an unhurried visit with a trained obstetrical nurse who offers pre-test counselling and explores reasons why patients refuse testing. We hypothesize that with this system, acceptance rates for HIV screening are significantly higher than the provincial average.
