Principal Investigator

Michael Heinrich

Study Purpose

The purpose of this study is to compare any good and bad effects of different starting doses of ponatinib, also called AP24534 or Iclusig, (the “study drug”), to determine which dose provides the best control of Chronic Phase Chronic Myeloid Leukemia (CP-CML) with the least amount of side effects. The use of the study drug could improve the status of your cancer, but it could also cause side effects. This study will allow the researchers to know whether this different approach is better, the same, or worse than the usual approach. To be better, the study drug should decrease the amount of detectable cancer in your blood.

Medical Condition(s)

Duration of Participation

The duration of the trial will be 24 months. You will undergo screening tests for up to 3 weeks prior to treatment to determine if you meet the criteria to participate in this trial. The length of time you will take ponatinib will depend on your cancer status (if you benefit from treatment) and how well you tolerate ponatinib.
