Double stem cell transplant could be Game-Changer for rare blood disorder
NCT ID NCT07499284
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding umbilical cord blood to a half-matched stem cell transplant can help people with aplastic anemia, a serious condition where the bone marrow stops making enough blood cells. About 224 participants aged 14 and older will receive either the combined transplant or standard care. The goal is to see if this approach improves survival, reduces complications like graft-versus-host disease, and helps the new stem cells take hold more successfully.

Inclusion Criteria: (1)Aged ≥14 years. (2) Patients diagnosed with aplastic anemia meeting the diagnostic criteria of the Chinese Guidelines for the Diagnosis and Management of Aplastic Anemia (2024 Edition). (3) Patients who were eligible for allogeneic bone marrow or peripheral blood hematopoietic stem cell transplantation in accordance with the Clinical Application and Management Specifications for Allogeneic Hematopoietic Stem Cell Transplantation Technology (2022 Edition). (4) The patient understands the study protocol and voluntarily signs the informed consent form. (5) Life expectancy of ≥3 months; (6) Pre-transplant assessment meets the following criteria: Karnofsky Performance Status (KPS) score≥70, Eastern Cooperative Oncology Group Performance Status (ECOG PS) score≤2, and Hematopoietic Cell Transplantation-Comorbidity Index (HCT-CI) score≤2. Exclusion Criteria: (1)Patients with aplastic anemia secondary to malignancy treatment or those with concurrent active malignancy. (2) Women who are pregnant or lactating. (3) Patients with psychiatric or psychological disorders that preclude adequate compliance with the treatment protocol. (4) Patients with positive serologic testing for any of the four major infectious diseases (hepatitis B, hepatitis C, syphilis, HIV). (5) Patients with systemic infection or localized severe infection requiring active antimicrobial therapy. (6) Patients with significant dysfunction of major organs (e.g., heart, lung, liver, kidney). (7) Patients with a known allergy or hypersensitivity to any drug or component used in this study. (8) Patients who are currently participating in or plan to participate in any other clinical trial. (9) Any other condition deemed by the investigator to render the patient unsuitable for study participation.
