7/25/2025	2400: Pre-TED	Add	Instructions updated on when Q12 comes due for subsequent transplants: The Research Sample Repository contains blood samples from unrelated recipients and/or their adult volunteer donors or cord blood units. Related allogeneic recipients and/or donors will participate at selected transplant centers. The primary objective of the Research Repository is to make blood samples available for research studies related to histocompatibility and hematopoietic cellular transplantation. Studies in which these data may be used include Improving the understanding of tissue matching for hematopoietic cellular donors and recipients. Determining and evaluating the factors that affect transplant outcomes. Studying the distribution of HLA tissue types in different populations (e.g., study tissue typing differences between different racial and ethnic populations to help develop methods to improve tissue matching between donors and recipients, including testing of rare HLA types). Indicate if the recipient signed an IRB-approved consent form to donate research blood samples to the NMDP / CIBMTR. If Yes (recipient consented), continue with _Date form signed. If No (recipient declined), Not approached, or Not applicable (center not participating), continue with Is the recipient participating in a clinical trial. For subsequent allogeneic transplants, this question is disabled, and blood samples are not submitted as consent and blood sample collection is only required for the first allogeneic transplant.

1/24/2025	AML Response Criteria	Add	Example 1 and 2 updated to further clarify 0% blasts in the blood is required to report CR for recipients with MDS / MPN who transformed to AML with residual MDS / MPN: Example 1: A recipient who transformed from MDS to AML received AML induction therapy. A bone marrow biopsy was performed post-induction and showed remission; however, there was still evidence of dysplasia present. The recipient did not receive additional therapy and went to transplant. In this scenario, the pre-transplant disease status may be reported as “CR” if all AML criteria are met in addition to having 0 % blasts in the peripheral blood. Example 2: A recipient who transformed from primary myelofibrosis to AML achieved remission following induction therapy and went to transplant. During the Day 100 reporting period, a bone marrow biopsy was performed and myelofibrosis was present. In this case, the post-transplant disease status may still be reported as “CR” if all AML criteria are met in addition to having 0 % blasts in the peripheral blood.

Additionally, therapy for measurable residual disease (MRD) may also be administered. Indicate if the recipient received treatment post-infusion for measurable residual disease (MRD), persistent, relapsed, or progressive disease in the current reporting period.
1/24/2025	2113: CLL Post-Infusion	Add	Clarified where MRD treatment is reported: Report the date when treatment for measurable residual disease (MRD), persistent, relapsed, or progressive disease was started in the current reporting period. If multiple treatments were started in the reporting period, report the date of the first treatment.

Recipients generally receive a HCT / cellular therapy under a specific protocol which defines radiation and / or systemic therapy to be given post-infusion, along with prophylactic medication as well as any systemic therapy, radiation, and / or other treatments to be administered post-infusion as planned (or maintenance) therapy. Planned (maintenance or consolidation) therapy is given to assist in prolonging remission. Planned therapy may be described in a research protocol or standard of care protocol and these should be referred to when completing this section. If post-infusion therapy is given as prophylaxis or maintenance for recipients in CR consider this ‘planned therapy,’ even if this was not documented prior to infusion. Do not include any treatment administered as a result of relapse, progression, or persistent disease. Indicate if therapy was given for reasons other than measurable residual disease (MRD), relapse, progressive, or persistent disease in the current reporting period.
