What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.
