Study summary

Multicentric prospective and retrospective register collecting patient with CML blast crisis diagnosed in Germany and Europe

Read the 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.

Study population

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

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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

Exclusion criteria

Exclusion Criteria:

  • Lack of
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Overall survival

    how many patients survive after a blast crisis event

    Time frame: through study completion in 2024

Secondary outcomes

  1. Rate of hematologic response to treatment

    how many patients have a hematologic response to the local standard Treatment after a blast crisis event

    Time frame: through study completion in 2024

  2. Rate of molecular response to treatment

    how many patients have a molecular response to the local standard Treatment after a blast crisis event

    Time frame: through study completion in 2024

  3. Rate of blast crises in Europe in the era of TKI treatment

    how many patients have blast crisis events compared to all treated CML-patients in the trial centers

    Time frame: through study completion in 2024
