7 Clinical Trials for Various Conditions
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 is a single center exploratory imaging study involving one intravenous microdose of 89Zr-DFO-VRC01 followed by whole-body PET-MR imaging in HIV infected individuals and healthy volunteers. Imaging data will be obtained from up to four static PE-MR images in order to determine dosimetry and temporal tissue uptake/tissue distribution of 89Zr-DFO-VRC01. This is not a treatment study of the biological activity of 89Zr-DFO-VRC01 to impact HIV persistence.
The purpose of this study was to evaluate the safety, tolerability, pharmacokinetics (PK), and antiviral activity of an antibody (called VRC01) in HIV-infected adults whose HIV was well-controlled with HIV medicines. The study examined whether VRC01 controlled or delayed the return of HIV viremia when the participants' HIV medicines were briefly stopped during the study.
The purpose of this study was to evaluate the safety, tolerability, and effect of an experimental human monoclonal antibody (mAb), VRC-HIVMAB060-00-AB (VRC01), in adults infected with HIV who were receiving antiretroviral therapy (ART).
Background: HIV causes AIDS, a serious disease that can lead to fatal infections. HIV infection can be controlled but not cured, nor is there a vaccine to prevent it. Antibodies may offer a promising new way to prevent HIV infection. Antibodies are proteins that are naturally made by the body to fight germs. One antibody (VRC01.23LS) has been tested in the lab and was found to block HIV-like viruses. Researchers want to find out if it is safe to inject VRC01.23LS into people. Objective: To test the safety of VRC01.23LS in healthy adults. Eligibility: Healthy people aged 18 to 60 years. Design: Participants will be divided into 6 groups: Some will get 1 dose of VRC01.23LS. They will visit the clinic up to 14 times in 24 weeks. Some will get 3 doses, each 12 weeks apart. They will have 25 clinic visits over 48 weeks. For some participants, the drug will be given through a tube attached to a needle inserted into a vein in the arm. This will take about 30 minutes. Others will receive the drug as an injection under the skin in a fatty area of the belly, arm, or thigh; each dose may need up to 3 individual injections. Participants will stay in the clinic up to 8 hours on the days they receive VRC01.23LS. Participants will receive a thermometer and measuring tool. They will check their temperature daily for 7 days after they receive the study drug. They will measure any redness, swelling, or bruising at the injection site.
This is the first clinical trial of the VRC-HIVMAB060-00-AB (VRC01) monoclonal antibody. VRC01 is a broadly neutralizing antibody directed against HIV. This is a dose-escalation study to examine safety, tolerability, dose and pharmacokinetics of VRC01. The hypothesis is that VRC01 will be safe for administration to HIV-1 infected adults by the intravenous (IV) and subcutaneous (SC) routes and will not elicit hypersensitivity reactions. Samples will be collected to learn if VRC01 is detectable in mucosal secretions and blood of participants and how long VRC01 can be detected in the blood after it is given. Between 15 and 25 HIV-1 infected adults, ages 18-70 years will be enrolled. There are 4 dose escalation groups for IV administration; the doses are 1 mg/kg, 5 mg/kg, 20 mg/kg and 40 mg/kg. There is 1 group for SC administration at 5 mg/kg. Each group is expected to include at least 3 participants. Each participant will receive two infusions of VRC01 with about 1 month between doses. Infusions are administered in an inpatient unit and an overnight stay at the NIH Clinical Center is required. No more than one subject per day per group will receive a first infusion of the VRC01 product by the IV route and no more than one subject per week will receive a first infusion of the product by the SC route. Study participation lasts for 24 weeks. Participant health and effect on CD4 count and HIV viral load will be monitored. Samples will be collected and stored for research purposes. ...
The purpose of this study was to assess the safety and pharmacokinetics (PK) of three monoclonal antibodies, VRC01, VRC01LS, and VRC07-523LS, in HIV-exposed infants who are at increased risk of mother-to-child HIV transmission.
