MINNEAPOLIS--(BUSINESS WIRE)--The National Marrow Donor Program® (NMDP)/Be The Match® in partnership with CIBMTR® (Center for International Blood and Marrow Transplant Research®) and the National Institute of Health’s National Heart, Lung, and Blood Institute (NHLBI) announced that the Journal of the American Medical Association (JAMA) published findings from the Pre-MEASURE study. The research explores a standardized method of assessing measurable residual disease (MRD) before allogeneic hematopoietic stem cell transplantation (HCT) in patients with acute myeloid leukemia (AML). It provides valuable insight into MRD as a predictive tool to inform HCT decisions and individualize treatment to improve outcomes.
“Allogeneic transplant is already an important treatment for many patients with AML. Unlocking the potential of precision medicine to improve it further will require a firm foundation of evidence. This Pre-MEASURE study demonstrates that it would be possible, using a blood test before transplant, to identify patients who may benefit from additional therapy beyond the current standard of care,” said Christopher Hourigan, DM, DPhil, FRCP, Chief of the Laboratory of Myeloid Malignancies, NHLBI.
The Pre-MEASURE study is the largest cohort of next-generation sequencing-based MRD testing (NGS-MRD) prior to allogeneic HCT for AML to date. It confirmed the ability to identify patients in complete remission (CR1) but at high risk of subsequent relapse using NGS-MRD testing pre-transplant. In addition, it found that reduced-intensity conditioning (RIC) was associated with a higher risk of relapse in those testing NGS-MRD positive. The research was conducted collaboratively by NMDP/Be The Match, CIBMTR, and NHLBI.
“NMDP/Be The Match is dedicated to ensuring that patients thrive following transplant. By developing standardized approaches for monitoring MRD before and after allogeneic HCT for AML allows physicians to create a personalized treatment approach that offers the best chances for success following HCT,” said Jeffery J. Auletta, MD, Senior Vice President, Patient Outcomes and Experience, NMDP/Be The Match; Chief Scientific Director, CIBMTR-NMDP; and Scientific Director, CIBMTR CRO Services. “We’re fortunate to have supported the Pre-MEASURE study featured in the Journal of The American Medical Association and to share the study’s findings for the benefit of patients everywhere. We are also supporting the forthcoming MEASURE study, which will standardize and optimize post-HCT MRD detection.”
In the Pre-MEASURE study, the team used ultra-deep error-corrected NGS techniques at a centralized NHLBI laboratory to determine if patients in clinical complete remission had MRD detectable by NGS-MRD before transplant, and how this was associated with outcomes for patients after transplant. Detection of persistent NPM1 and/or FLT3-ITD mutations was observed in 17.3% of patients (approximately 1 in 6) before transplant and was associated with significantly increased relapse and worse survival after transplant. Detecting MRD before transplant helps transplant teams identify patients at greater risk of relapse. Transplant teams could, in the future, alter the treatment plan for those patients to give them the best possible chance of optimal outcomes. The findings of this research provide evidence in support of a precision medicine approach for adult patients with AML undergoing transplant and are currently being implemented in a prospective clinical protocol at transplant centers throughout the United States.
The study was also presented at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting in June 2022. (Dillon LW, Gui G, Page KM, et al.
