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

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

60 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

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.
Outcome Measure
Measure Description
Time Frame
Occurrence of Dose Limiting Toxicities
Time Frame: 4 Weeks

Dose limiting toxicity (DLT) was defined as any of the following adverse events occurring by Day 29 (7 days after the last investigational medicinal product [IMP] administration) of this trial for which a causal relationship to the IMP could not be ruled out. Severity of the adverse events was evaluated in accordance with the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) ver. 4.0. Blood toxicity did not include hematology parameters of laboratory tests.

  • Non-blood toxicities ≥ Grade 3, excluding cases of anorexia, nausea, vomiting, diarrhea, and constipation where it is possible to continue the clinical trial by use of supportive therapy
  • Blood toxicities ≥ Grade 4, although febrile neutropenia ≥ Grade 3 will be counted as DLT.
4 Weeks

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.
Outcome Measure
Measure Description
Time Frame
Recurrence Based on the Response Evaluation Criteria by the International Working Group
Time Frame: 4 weeks
A case will be designated as relapse if any of the following occur. Reappearance of leukemic blast cells in the peripheral blood or ≥5% blast cells in the bone marrow after complete remission (morphologic relapse).
4 weeks

Primary Completion (Actual)

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.
