Study Description

Brief summary:

Additional information is needed to characterize the safety profile of ponatinib as it is used in routine clinical practice in Europe. This observational cohort study will provide a real-life picture of ponatinib use in clinical practice and additional quantification and characterization of adverse events (AEs) and their outcomes in patients with Chronic Myeloid Leukemia in any phase treated with ponatinib.

  • Condition or Disease:Chronic Myeloid Leukemia, Chronic Phase
  • Intervention/Treatment:
  • Phase: N/A

Detailed Description

This study is a multicentre, long-term, prospective and retrospective, observational cohort study of patients who are treated with ponatinib. The study is non-interventional; all Treatment decisions are made at the discretion of the patient's healthcare provider (HCP) and are not mandated by the study design or protocol. A heterogeneous sample of oncology practice sites in Germany (both Hospitals and Field based Haematologists) treating adult patients with Chronic Myeloid Leukemia in any phase using ponatinib will be selected for participation in the study. Eligible, consenting patients initiating treatment with ponatinib will be enrolled into the prospective part of the study. Eligible consenting patients with Chronic Myeloid Leukemia in any Phase that have initiated ponatinib outside clinical trial after its approval in Germany will be enrolled in the retrospective part of the study. Approximately 100 patients will be enrolled from approximately 50 sites. The patient enrolment period is estimated to be approximately two years. Patients who experience an Adverse Event (AE) during treatment or within the 30 days post discontinuation will be followed for 12 months to determine the consequences of the Adverse Event. Data on patient's history, patient's data at baseline, ponatinib treatment, Adverse Events, all medications received, and efficacy measures will be collected during the study in conjunction with routine care visits, anticipated to be approximately every 3 months. Information on any new therapies, including treatment for Chronic Myeloid Leukemia and other medications will be collected during follow-up.

Study Design

  • Study Type: Observational
  • Estimated Enrollment: 100 participants
  • Observational Model: Case-Only
  • Time Perspective: Retrospective
  • Official Title: Observational Study on Chronic Myeloid Leukemia Patients in Any Phase Treated With Ponatinib (Iclusig®) at Any Dose
  • Actual Study Start Date: July 2015
  • Estimated Primary Completion Date: December 2022
  • Estimated Study Completion Date: December 2022

Outcome Measures

  • Primary Outcome Measures: 1. Change in Cytogenetic response [ Time Frame: through study completion, an average of 3 years ]
    Achievement of cytogenetic Response (percentage of Ph+ metaphases)
  • 2. Molecular response [ Time Frame: through study completion, an average of 3 year ]
    BCR-ABL in % (lower is better)

Eligibility Criteria

  • Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
  • Sexes Eligible for Study: All
  • Accepts Healthy Volunteers: No
  • Sampling Method: Non-Probability Sample
  • Study Population: The study will include patients with Chronic Myeloid Leukemia in any phase that are initiating or have initiated treatment with ponatinib and who meet the enrolment criteria and provide informed consent. A group of patients, for whom the decision of starting ponatinib has already been made, but in whom ponatinib has not yet been started, will be identified prospectively and invited to enrol into the study. The study enrolment date is the date the informed consent is signed. An additional group of patients who have received or are receiving ponatinib treatment outside clinical trials will be invited to join the retrospective part of the study.


Inclusion Criteria:

- Adult patients (age ≥18 years) with Chronic Myeloid Leukemia in any phase who are
initiating ponatinib monotherapy, or for whom ponatinib monotherapy was initiated
after ponatinib approval in Germany. [The decision to prescribe ponatinib must have
been made prior to enrolment in the study. Patients enrolled in the retrospective part
of the study may or may not be still on ponatinib treatment at the time informed
consent is given. These retrospective patients should have started Treatment after

- Patients who have the ability to understand the requirements of the study, and provide
written informed consent to comply with the study data collection procedures.

- Patients with a minimum life expectancy of 3 months

Exclusion Criteria:

- Patients previously treated with investigational ponatinib (within a clinical trial)

- Patients receiving an investigational agent

- Patients who are pregnant and/or breastfeeding

- Patients who are pregnant and/or breastfeeding
