The purpose of this study is to study the safety and feasibility of giving intestinal transplant patients CD34+ stemcells (the cells that make all the types of blood cells) obtained from their organ donor's bone marrow as an IV…
The purpose of this study is to see whether or not the medicine, Abatacept, when given after hematopoietic stemcell transplantation (HSCT) is effective in treating GVHD in children and adolescents with sickle cell disease (SCD). We are also planning to gather…
The purpose of this study is to test a new medicine to prevent liver venoocclusive disease (VOD) in patients undergoing hematopoietic stemcell transplant (HSCT) who are at high risk or very high risk for liver VOD following HSCT. Liver VOD can be a complication of bone marrow and/or…
The main purpose of the study is to find out about whether the study drug is safe in humans and aneffective treatment in pediatric patients with acute Graft versus Host Disease (GVHD). GVHD mayoccur after a bone marrow or stemcell transplant in which someone receives bone marrow tissue or…
Are you undergoing a stemcell transplant? You may be at high risk for infections after the transplant. This study is looking at the safety and effectiveness of an investigational medication for those who have undergone a stemcell…
The primary objectives of this study are to measure the safety and effectiveness of bone marrow transplant (BMT) using specific chemotherapy in children with less severe SCD and to understand the long term effects of bone marrow transplant in children with SCD, by evaluating ovarian reserve, sickle cell related brain problems…
In this trial, we will evaluate whether partially-HLA matched allogeneic multivirus-specific VSTs, will be safe and produce anti-viral effects in immunodeficient recipients infected with one of more of the targeted viruses that are persistent despite conventional anti-viral therapy. This will be in patients who have received a hematopoietic…
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…
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…
