EWING, N.J., Dec. 12, 2013 (GLOBE NEWSWIRE) -- Celator Pharmaceuticals, Inc. (Nasdaq:CPXX), a pharmaceutical company developing new and more effective therapies to treat cancer, today announced that the independent Data and Safety Monitoring Board (DSMB) for the Company's Phase 3 clinical study comparing CPX-351 (cytarabine:daunorubicin) Liposome Injection versus the conventional cytarabine and daunorubicin treatment regimen (commonly referred to as 7+3 ) as first-line therapy in older patients with high-risk (secondary) acute myeloid leukemia (AML) should continue as planned without any modifications.
"We are encouraged by the progress of the study and the DSMB's recommendation," said Arthur Louie, Chief Medical Officer of Celator Pharmaceuticals. "This is the first safety review of available data from the Phase 3 study and we look forward to reporting updates as the study progresses and to completing enrollment of the study in 2014."
The DSMB assessment was based on a pre-planned safety analysis on the first 75 randomized patients included in the study with a minimum of 60 days of follow-up. The DSMB will conduct additional periodic reviews after 150 patients, 225 patients and 300 patients become evaluable for safety review.
The Phase 3 study is being conducted in partnership with The Leukemia & Lymphoma Society® (LLS) through its Therapy Acceleration Program (TAP), which has supported the development of CPX-351 beginning in Phase 2.
The study (Protocol NCT01696084) is currently enrolling patients between the ages of 60 and 75 who have pathological diagnosis of AML according to WHO criteria (with at least 20% blasts in the peripheral blood or bone marrow) with confirmation of:
- Therapy-related AML
- AML with a history of myelodysplasia (MDS)
- AML with a history of chronic myelomonocytic leukemia (CMMoL)
- De novo AML with karyotypic abnormalities characteristic of MDS
Patients are randomized 1:1 to receive either CPX-351 (100u/m2; Days 1, 3, and 5 by 90 minute infusion) or 7+3 (cytarabine 100mg/m2/day by continuous infusion for 7 days and daunorubicin 60mg/m2 on days 1, 2, and 3). Patients are monitored for all clinical adverse events as well as laboratory evaluations. The primary efficacy endpoint of the study is overall survival. The study is being conducted in the United States and Canada with approximately 40 leading cancer centers expected to participate.
