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.

Detailed Description

Since the advent of treatment with tyrosine kinase inhibitors (TKI), the incidence of blast crises has significantly decreased. Nevertheless, about 5% of patients diagnosed with chronic myeloid leukemia (CML) will evolve into a blast phase at some point during the course of their disease. Furthermore, despite the advances made in CML treatment, outcome of patients with blast crises are still dismal. Due to the rarity of this condition clinical trials are challenging, and collaboration between researchers both at national and international level is needed to collect a meaningful number of data.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Patients with CML Blast crisis, either newly diagnosed or as evolution of a CML in chronic phase

Description

Inclusion Criteria:

  • Age >18 years

  • Diagnosis of BCR-ABL positive CML blast crisis according to the WHO criteria:

    • Blasts 20% or more of peripheral blood white cells or bone marrow cells or
    • Extramedullary blast proliferation or
    • Large foci or clusters of blasts in bone marrow biopsy

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
Overall survival
Time Frame: through study completion in 2024
how many patients survive after a blast crisis event
through study completion in 2024

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
Rate of hematologic response to treatment
Time Frame: through study completion in 2024
how many patients have a hematologic response to the local standard Treatment after a blast crisis event
through study completion in 2024
Rate of molecular response to treatment
Time Frame: through study completion in 2024
how many patients have a molecular response to the local standard Treatment after a blast crisis event
through study completion in 2024
Rate of blast crises in Europe in the era of TKI treatment
Time Frame: through study completion in 2024
how many patients have blast crisis events compared to all treated CML-patients in the trial centers
through study completion in 2024

Primary Completion (Anticipated)

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.
