Celator Pharmaceuticals, Inc., a biopharmaceutical company that is transforming the science of combination therapy and developing products to improve patient outcomes in cancer, today announced that patients have been enrolled in an investigator-initiated Phase 2 clinical study evaluating CPX-351 (cyatarabine:daunorubicin) Liposome Injection as a treatment for patients with newly diagnosed Acute Myeloid Leukemia (AML) at high risk for induction treatment mortality.
"Patients with newly diagnosed AML at increased risk of early death urgently need safer and more effective treatment," said Jorge Cortes, M.D., Deputy Department Chair, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center. "Our earlier experiences with CPX-351 in newly diagnosed and first relapse AML patients make us optimistic about this trial."
Phase 2 studies with CPX-351 observed improved efficacy and reduced early mortality in the majority of patients studied directly supporting evaluating CPX-351 in this population of newly diagnosed AML patients at high risk for induction treatment mortality.
The Phase 2 study will enroll up to 55 patients, with the primary objective to assess the preliminary efficacy and safety of multiple dose levels of CPX-351 in patients with newly diagnosed AML at high risk for induction treatment mortality. High risk for induction treatment mortality is defined as 30%-50% predicted risk of expiring by day 60. Estimation of risk for induction treatment mortality will be based on factors associated with lower likelihood of AML response with or without factors that reduce tolerance to treatment-associated adverse events. Every patient must have at least one AML-related factor (adverse cytogenetics, secondary AML, MDR phenotype, etc.) that contributes to elevated risk of induction treatment mortality. Patients may or may not have patient-related factors (poor performance status, co-morbidities, poor organ function, etc.) that also contribute to elevated risk of induction treatment mortality.
"We are pleased that Dr. Cortes and MD Anderson Cancer Center chose to study CPX-351 in this patient population," said Arthur Louie, Chief Medical Officer of Celator Pharmaceuticals. "As we await overall survival data from our CPX-351 Phase 3 trial in patients with high-risk AML, we believe there is significant potential for CPX-351 in other AML populations as well as other blood cancers, and we believe it important to evaluate these opportunities."
