Top Cities for Organ Transplant Clinical Trials
Organ Transplant clinical trials are recruiting across 59 cities. Here are the cities with the most active studies:
Organ Transplant Trial Phases
45 research organizations are sponsoring organ transplant trials.
About Organ Transplant
Organ transplantation is a surgical procedure to replace a diseased organ with a healthy one from a donor. Managing rejection through immunosuppressive medications is a lifelong requirement. Research continues to improve outcomes through better immunosuppression, organ preservation, and xenotransplantation.
Clinical trials are advancing new treatments for organ transplant. Currently, 57 studies are recruiting a combined 200,273,876 participants across the United States. Research is being conducted by 45 organizations including Center for International Blood and Marrow Transplant Research, M.D. Anderson Cancer Center, University of Minnesota and 42 others.
2026 Organ Transplant Research Landscape
As of July 2026, the organ transplant clinical trial landscape includes 57 actively recruiting studies across 59 cities in the United States. These studies are collectively seeking 200,273,876 participants, with an average enrollment target of 3,513,577 per study.
The research spans multiple phases of development: 16 studies are in NA, 9 studies are in PHASE2, 5 studies are in PHASE4, 5 studies are in PHASE1, 4 studies are in PHASE3, 4 studies are in EARLY_PHASE1.

The Collection and Storage of Umbilical Cord Blood for Transplantation
The goal of this study is to collect blood samples from the umbilical cords of newborn babies, as soon as they are delivered, and to place these samples in the MD Anderson Cord Blood Bank. Your sample may be included in the National Cord Blood Inventory (NCBI) which is part of the CW Bill Young Cell Transplantation Program. The NCBI is a federally-supported program to assist in the collection of c...
