Trial Outcomes & Findings for Transplantation of Partially Mismatched Related or Matched Unrelated Bone Marrow for Patients With Refractory Severe Aplastic Anemia (NCT NCT02224872)

NCT ID: NCT02224872

Last Updated: 2023-03-10

Results Overview

Feasibility will be met with the following conditions: the patient has the transplant, is assessed for the safety endpoint, and survives one year. The safety monitoring plan is included to monitor graft failure (day 60), grade 2-4 acute graft versus host disease (day100), 6 month mortality (day 180), and chronic graft versus host disease (day 180).
