PONS = Ponatinib in Second Line [Germany]

What is the purpose of the study

This is a non-randomized, open label study evaluating the safety and efficacy of second line ponatinib therapy in patients suffering from Chronic Myeloid Leukemia in Chronic Phase and who are resistant or intolerant to earlier treatment with another Tyrosine Kinase Inhibitor (TKI). Ponatinib will be given at a dose of 30mg. The dose may be reduced further to 15mg. The study is being performed in Germany.

Key inclusion criteria

Adult patients (age ≥ 18) diagnosed with Ph-positive (by cytogenetics) or BCR-ABL-positive (by PCR) chronic myeloid leukemia (CML) in chronic phase.

Patients should have demonstrated to have
– a failure of a prior first line TKI treatment with either imatinib, dasatinib or nilotinib, defined as per European LeukemiaNet (ELN) recommendations,
– or intolerance to prior TKI treatment defined as grade 3 or 4 toxicity, or persistent grade 2 toxicity despite optimal management including dose adjustment, or in a patient where dose reductions are considered to be not in the patient’s best interest to obtain an adequate response. Intolerant patients should not have achieved or have lost major cytogenetic molecular response at the time of enrollment.

Patients should also have an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2, as well as adequate function of liver, kidney and pancreas. Patients should have fully recovered from the acute effects of prior cancer therapy.

Pregnant patients cannot be included.

Additional criteria may apply.
