NMDP to Present New Stem Cell Transplantation Data at the 2024 American Society of Clinical Oncology Annual Meeting

-- April 24 2024

MINNEAPOLIS, April 24, 2024 – NMDPSM, a global nonprofit leader in cell therapy, and CIBMTR® (Center for International Blood and Marrow Transplant Research®) will present new data on hematopoietic cell transplantation (HCT) treatment effects in patients with hematological malignancies at the American Society of Clinical Oncology (ASCO) Annual Meeting May 31–June 4, 2024, in Chicago, Ill., and online. A chief focus will be sharing interim findings from ACCESS, the prospective, multi-center, Phase II clinical trial of HCT using human leukocyte antigen (HLA)-mismatched unrelated donors (MMUD) for peripheral blood stem cell transplant in adults and bone marrow stem cell transplant in children.

“New findings from the ACCESS study will advance broader understanding of how mismatched unrelated donors can safely and effectively address gaps in equitable access to transplant for those patients who are unable to find a fully matched donor,” said Steven M. Devine, M.D., Chief Medical Officer, NMDP; Senior Scientific Director, CIBMTR. “Acceptance to present our collective work is not only an honor, it’s a recognition that advancing the evidence base for MMUD transplant for patients with blood cancers and blood disorders remains of global importance to finding new cures and saving more lives.”

CIBMTR is a research collaboration between the Medical College of Wisconsin and NMDP, advancing research in cellular therapies to improve patient outcomes.

About the ACCESS Trial

ACCESS (NCT04904588) is a multi-center, Phase II study of hematopoietic stem cell transplantation (HCT) using mismatched unrelated donors (MMUD) for peripheral blood stem cell (PBSC) transplant in adults and bone marrow stem cell transplant in children. This trial completed enrollment in its adult arms ahead of schedule and is continuing to enroll within its pediatric arm. ACCESS aims to expand upon previous peer-reviewed findings of its 15-MMUD trial (NCT02793544) that showed encouraging three-year outcomes in the use of post-transplant cyclophosphamide in MMUD HCT, and a recent observational study that established no discernable differences in graft-versus-host disease, relapse-free survival or overall survival for patients who had a hematopoietic cell transplant (HCT) with an 8/8 or 7/8 unrelated donor for adult patients with hematologic malignancies.


CIBMTR® (Center for International Blood andMarrow Transplant Research®) is a nonprofit research collaboration between NMDPSM, in Minneapolis, and the Medical College of Wisconsin, in Milwaukee. CIBMTR collaborates with the global scientific community to increase survival and enrich quality of life for patients. CIBMTR facilitates critical observational and interventional research through scientific and statistical expertise, a large network of centers, and a unique database of long-term clinical data for more than 630,000 people who have received hematopoietic cell transplantation and other cellular therapies.
