Completed
Conditions
Accelerated Phase Chronic Myelogenous Leukemia
Blastic Phase Chronic Myelogenous Leukemia
Philadelphia Chromosome-positive Acute Lymphoblastic Leukemia
Chronic Phase Chronic Myelogenous Leukemia
Registration Number
NCT03647215
Lead Sponsor

Brief Summary

A multicenter, prospective cohort study of the mutation status of patients with chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) who are being treated with first or subsequent tyrosine kinase inhibitor (TKI) therapy in the UK, Ireland, or France.

Recruitment & Eligibility

Status
COMPLETED
Sex
All
Target Recruitment
427
Inclusion Criteria
  • Adult patients (age ≥ 18 years) with CML (in all phases of disease) or Ph+ ALL with detectable BCR-ABL levels who are being treated with a first or subsequent TKI.

  • Patients with CML must meet the warning or failure criteria as per the ELN guidelines for first second and subsequent treatment line, including:

    • BCR-ABL/ABL IS transcripts > 10% at 3 months
    • BCR-ABL/ABL IS transcripts > 1% at 6 months
    • BCR-ABL/ABL IS transcripts > 0.1% at 12 months or later
  • Patients with CML must not currently be in MMR (ie, have disease with BCR-ABL1/ABL1 transcripts > 0.1% IS).

OR

  • Patients with Ph+ ALL with any level of BCR-ABL/ABL IS transcripts. Patients with Ph+ ALL should have BCR-ABL1/ABL1 transcript levels > 0.1% and should not be currently enrolled in UKALL14 but may have relapsed during or after participation in UKALL14.
  • Patients with an intermediate or high Sokal score (> 0.8) can be recruited into the study from 3 months after diagnosis, irrespective of BCR-ABL1/ABL1 transcript levels at 3 months.
  • Patients with additional chromosomal abnormalities at diagnosis and patients with AP-CML may be recruited into the study, irrespective of BCR-ABL1/ABL1 transcript levels at 3 months and beyond provided BCR-ABL1/ABL1 transcript levels are > 0.1% IS. It is recommended that these patients have mutational analysis performed every 3 months irrespective of BCR-ABL1/ABL1 transcript levels until they reach MR3/MMR (BCR-ABL1/ABL1 < 0.1% IS).
  • Any patients who have previously undergone testing for KD mutations, irrespective of KD mutational analysis test results.
  • Patients who have the ability to understand the requirements of the study and provide written informed consent.
Exclusion Criteria

Patients without detectable BCR-ABL and patients who have switched TKI due to intolerance but who have met the criteria for optimal response (CP-CML, ELN 2013 guidelines).
