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
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult patients with malignant hematologic diseases who are eligible for allogeneic hematopoietic stem cell transplantation

Description

Inclusion Criteria:

  • Aged 19 and older
  • Patients scheduled for umbilical cord blood transplantation as a primary allogeneic hematopoietic stem cell transplantation for the treatment of the following hematologic diseases:

Acute leukemia (myeloid/lymphoid/mixed lineage) / Myelodysplastic syndromes / Chronic leukemia (myeloid/lymphoid/monocytic) and myeloproliferative neoplasms / Malignant lymphomas, multiple myeloma / Other malignant hematologic malignancies / bone marrow failure diseases, including aplastic anemia

- If all contents of the consent form are understood and consented to in writing.

Exclusion Criteria:

  • Patients with a history of allogeneic hematopoietic stem cell transplantation or those undergoing transplantation for the treatment of engraftment failure (secondary allogeneic hematopoietic stem cell transplantation is an exclusion criterion; however, patients eligible for registration include those undergoing their first allogeneic stem cell transplantation following an autologous stem cell transplantation).
  • Patients with severe, uncontrolled infections or severe cardiopulmonary dysfunction, as judged by the investigator.
  • Patients with an ECOG Performance Status (PS) greater than 3 or those receiving mechanical ventilation in the intensive care unit.
  • Patients who do not consent to participate in the study or those deemed unsuitable for sincere participation by the attending physician.

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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 21, 2023

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
