The PACE trial is a global, single-arm clinical study of oral ponatinib in 320 patients with chronic phase, accelerated phase, or blast phase CML, as well as Ph+ ALL. Patients resistant or intolerant to dasatinib (Sprycel(R)) or nilotinib (Tasigna(R)), or with T315I mutation of BCR-ABL, will be enrolled in the trial. Patients will be grouped into one of six separate cohorts based on their phase of CML (i.e., chronic, accelerated or blast) and BCR-ABL mutation status (i.e., with or without the T315I mutation); Ph+ ALL patients will be grouped with blast phase CML. A total of 160 patients with chronic phase CML will be included. The primary endpoints are major cytogenetic response rate for chronic phase patients and major hematologic response rate for accelerated or blast phase CML patients and Ph+ ALL patients. Secondary endpoints in the trial include major molecular response rate, duration of response, progression-free survival, and overall survival.

Patients will receive ponatinib in tablet form once daily at a dose of 45 mg. The PACE trial will be conducted at approximately sixty centers in North America, Europe, Australia and Asia. Full patient enrollment is anticipated by year-end 2011.

"Clinical results from the ongoing Phase 1 trial of ponatinib, taken together with the preclinical data that characterize ponatinib as a potent, pan-BCR-ABL inhibitor, provide a strong rationale for advancing directly to a pivotal trial of ponatinib in a population of patients who have extremely limited, if any, treatment options," stated Jorge Cortes, M.D., professor and deputy chair, Department of Leukemia, The University of Texas MD Anderson Cancer Center and a leading investigator in the PACE trial. "There is great interest in the PACE trial from clinicians and patients, and I look forward to having this investigational option available for patients with this disease."
