Despite significant progress in the treatment of patients with chronic phase CML, there is still need to further optimize therapy to reach the goal of disease eradication for almost all patients. In case of imatinib failure, dasatinib and nilotinib are effective treatment options after an individualized treatment selection. Although MMR rates of around 30% after 2 years of therapy are a significant achievement, options that may improve response rates in depth are still desirable. Ponatinib is a third generation TKI with very high anti-clonal activity in all CML phases. Moreover, it also eradicates most of the known and problematic mutations and only very few (compound) mutations may induce ponatinib-resistance.
Based on its favourable target spectrum, it is expected that Ponatinib may be more effective than 2nd line dasatinib or nilotinib in achieving early (i.e., at 6 months) cytogenetic and molecular responses in patients after inappropriate response to imatinib, and more effective as 2nd line treatment after failure of initial treatment with dasatinib or nilotinib than a cross-over between the 2nd generation TKIs. The basic hypothesis underlying therapeutic programs in CML is to be able to achieve meaningful and long-lasting suppression of the Philadelphia chromosome and breakpoint cluster region-abelson fusion gen (BCR-ABL). Complete cytogenetic responses have been associated with improved survival in CML, while major molecular responses are associated with improved event-free survival.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||54 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Phase 2 Clinical Trial With Ponatinib as a Second Line Therapy for Patients With Chronic Myeloid Leukemia in Chronic Phase Resistant or Intolerant to Prior First Line Tyrosine Kinase Inhibitor Treatment|
|Actual Study Start Date :||December 11, 2018|
|Estimated Primary Completion Date :||October 2020|
|Estimated Study Completion Date :||April 2023|
Patients in this treatment arm receive Ponatinib: starting dose 30 mg once-daily. Doses may be increased in case of inappropriate response and reduced to manage drug-related adverse events (AEs) and may be re-escalated once events resolve.
2 film-coated tablets à 15mg for oral administration on a daily basis

- Major Molecular Response (MMR) of treatment [ Time Frame: by 12 moths ]To estimate the proportion of CP-CML patients with tyrosine kinase inhibitor (TKI)-resistance or intolerance to first line therapy with TKI, attaining MMR by 12 months of treatment with second line Ponatinib therapy.
- Time to toxicity [ Time Frame: up to 24 months ]To evaluate the toxicity profile of ponatinib in patients with CML in chronic phase after one TKI failure toxicities will be followed up at each visit during the treatment phase and will be assessed using CTCAE v.5.0. Type of toxicity (hematologic or non-hematologic) along with the grading will be followed up on.
- Time to response [ Time Frame: at 3, 6, 9, 12, 18 and 24 months ]To estimate the time to CCyR, MMR, MCyR and MR4 for patients treated with Ponatinib as second line therapy for CP-CML (chronic phase-chronic myelogenous leukemia).
- Durations of response [ Time Frame: at 3, 6, 9, 12, 18 and 24 month ]To evaluate the duration of hematologic, cytogenetic and molecular response to Ponatinib after one TKI failure.
- Occurrence of BCR-ABL-mutations [ Time Frame: at 3, 6, 9, 12, 18 and 24 months ]To evaluate the occurrence of BCR-ABL-mutations in patients with failure of Ponatinib 2nd line therapy.
- Time to progression [ Time Frame: at 3, 6, 9, 12, 18 and 24 months ]To define the time to progression for patients with CML in chronic phase treated with Ponatinib after one TKI failure.
- Time to overall survival [ Time Frame: at 3, 6, 9, 12, 18 and 24 month ]To define the time to overall survival for patients with CML in chronic phase treated with Ponatinib after one TKI failure.
