The Efficacy and Safety of Stereotactic Radiotherapy Bridging Allogeneic Hematopoietic Stem Cell Transplantation for the Treatment of Hematological Malignance Patients With Extramedullary Infiltrating

March 4, 2026 updated by: Institute of Hematology & Blood Diseases Hospital, China
Application of Stereotactic Body Radiotherapy (SBRT) Bridging to Allogeneic Hematopoietic Stem Cell Transplantation in Adult Hematological Malignance Patients with Extramedullary Lesions. This study aims to improve transplantation outcomes with extramedullary lesions. The investigators aim to study the Post-Transplantation Evaluation of Disease-Free Survival, Overall Survival, Treatment-Related Mortality, Cumulative Recurrence Rate, Post-Transplantation Complications, and Safety Data.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Description

Inclusion Criteria:

Subjects who meet all of the following criteria are eligible for enrollment in this study:

  • Age between 18 and 60 years.
  • A confirmed diagnosis of a hematologic malignancy, including but not limited to Acute Myeloid Leukemia (AML), Acute Lymphoblastic Leukemia (ALL), Chronic Myeloid Leukemia (CML), Myelodysplastic Syndromes (MDS), Non-Hodgkin Lymphoma (NHL), Hodgkin Lymphoma (HL), and Multiple Myeloma (MM).
  • Diagnosis of extramedullary disease/lesions confirmed by one of the following: pathological biopsy, cytology, or at least one imaging modality (including PET-CT, contrast-enhanced CT, or contrast-enhanced MRI).
  • Presence of a suitable donor and scheduled to undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT).
  • Karnofsky Performance Status (KPS) score > 60% or Eastern Cooperative Oncology Group Performance Status (ECOG PS) score of 0 to 2.
  • Has not participated in any other clinical trial involving cell-based or immunotherapies for the treatment of the primary disease.
  • The subject voluntarily agrees to participate in the study, demonstrates good compliance, and is willing to cooperate with follow-up procedures.
  • A signed informed consent form must be obtained prior to the initiation of any study-related procedures. For subjects aged 18 years or older, consent is to be provided by the subject or their immediate family member. If, in the physician's judgment, obtaining consent directly from the subject is not in the patient's best interest regarding their medical condition, the informed consent form may be signed by the legal guardian or an immediate family member of the patient

Exclusion Criteria:

  • Previous history of one or more autologous or allogeneic stem cell transplants prior to enrollment.
  • Uncontrolled infection at the time of enrollment, or requirement for mechanical ventilatory assistance, or hemodynamic instability.
  • Severe organ dysfunction, including but not limited to hepatic or renal impairment, and heart failure.
  • Evidence of active HIV replication; positive HCV antibody and detectable HCV-RNA within 90 days prior to enrollment; or positive HBsAg. Known seropositivity for HIV or active hepatitis C virus.
  • Presence of psychiatric disorders or any other condition that, in the investigator's opinion, would compromise the subject's ability to cooperate with study treatment and monitoring requirements.
  • Inability or unwillingness to provide written informed consent.
  • Any other condition or circumstance that, in the judgment of the investigator, may pose a risk to the subject or prevent the subject from meeting or fulfilling the study requirements.

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.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
