February 27, 2026 updated by: Institute of Hematology & Blood Diseases Hospital, China

A Clinical Study on the Efficacy and Safety of Luspatercept in Improving Early Anemia After Allogeneic Hematopoietic Stem Cell Transplantation

This study aims to evaluate whether luspatercept can improve the efficacy and safety of anemia treatment in patients with hematologic malignancies after allogeneic hematopoietic stem cell transplantation.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study aims to investigate whether the early post-transplant application of luspatercept can improve early anemia and transfusion dependency in patients with hematologic malignancies after hematopoietic stem cell transplantation. Meanwhile, the investigators aim to evaluate the safty of administration of luspatercept post-transplantation, and assess its impact on platelet and neutrophil engraftment, as well as its effect on the incidence of complications such as poor graft function.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 1. Diagnosis of malignant hematological tumors and undergoing allogeneic hematopoietic stem cell transplantation.
  • 2. Expected survival after transplantation exceeds 1 month.
  • 3. Age 18-60 years.
  • 4. Hemoglobin ≤60 g/L on day 0 after transplantation.
  • 5. Eastern Cooperative Oncology Group (ECOG) score 0-2.
  • 6. Able to independently sign the informed consent form.
  • 7. The informed consent form must be signed before the start of the study procedures. For individuals aged 18 years and above, the informed consent form should be signed by the patient themselves or their immediate family members. Considering the patient's condition, if signing by the patient themselves is not conducive to treatment, the legal guardian or immediate family member should sign the informed consent form.

Exclusion Criteria:

  • 1. Uncontrolled infection at the time of enrollment, or requiring mechanical ventilation or hemodynamic instability;
  • 2. Severe organic damage: hepatic or renal impairment;
  • 3. Occurrence of any of the following within 6 months prior to the study: myocardial infarction, severe/unstable angina pectoris, congestive heart failure, or cerebrovascular accident, including transient ischemic attack;
  • 4. Presence of psychiatric disorders or other conditions that may compromise compliance with study treatment and monitoring requirements. Failure to sign the informed consent form;
  • 5. Inability or unwillingness to sign the consent form;
  • 6. Participation in other transplant-related clinical studies;
  • 7. Other circumstances deemed by the investigator as potentially affecting the study or ethics, including drug allergies, patient non-compliance with study procedures, or involvement of the research center staff and their immediate relatives.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Luspatercept treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
