This study is for patients who have been diagnosed with Multiple System Atrophy (MSA). The main goals of this study are to determine how safe and well tolerated AZD3241 is in patients who have MSA, and whether AZD3241 has certain effects in the brain of patients with MSA. These effects in the brain are measured with positron…
This trial is testing two experimental vaccines for HIV called DV700P-RNA and DV701B1.1-RNA. This trial is a Phase 1 study testing whether these vaccines are safe to use in people and can be taken comfortably, as well as how the immune system responds to the vaccines.Both vaccines are made using messenger ribonucleic acid (…
The HIV Vaccine Trials Network, Division of AIDS, and Columbia University Irving Medical Center are conducting a trial to learn about the safety and effectiveness of 3 experimental HIV vaccines. This is a first-in-human phase 1 clinical trial of experimental HIV vaccines utilizing the mRNA vaccine platform. The 3 different experimental vaccines being tested…

The HIV Vaccine Trials Network (HVTN) and Columbia University Irving Medical Center (CUIMC) are conducting a study to learn about the safety and effectiveness of an experimental HIV vaccine. The study vaccine is a protein vaccine called N332-GT5 gp140. It includes a manmade protein that looks like a protein found on the outside of HIV. The study vaccine is…
This study is designed to test how well an intravenous human immunoglobulin concentrate, IGIV-C (compared with placebo) improves your muscle weakness associated with MG symptoms. A placebo is a medication that looks like the study medication but has no active ingredient. Immunoglobulin is an antibody produced by white blood cell…
This study is designed to test how well an intravenous human immunoglobulin concentrate, IGIV-C (compared with placebo) improves the ability to taper participant's dose of corticosteroids without causing significant increase in your muscle weakness and worsening MG symptoms. A placebo is a medication that looks like the study medication but has no active…
The HIV Vaccine Trials Network, Division of AIDS, and Columbia University Irving Medical Center are conducting a trial to learn about the safety and effectiveness of two new experimental HIV vaccines. This is a first-in-human phase 1 clinical trial where we will be testing 2 study vaccines, CH505M5 N197D mRNA-gp160 and CH505 TF mRNA-gp160. The goal is to…
The purpose of this study is to see how safe and well tolerated the study drug BMS-986168 is at different drug amounts and to measure the amount of study drug in your blood and cerebrospinal fluid (CSF) after taking the drug. This study will also measure the effect of the study drug on the amount of extracellular Tau (eTau) in…
