Celator® Pharmaceuticals Presents Data at the American Association for Cancer Research Annual Meeting
EWING, N.J., April 22, 2015 /PRNewswire/ -- Celator Pharmaceuticals, Inc. (Nasdaq: CPXX), a biopharmaceutical company that is transforming the science of combination therapy and developing products to improve patient outcomes in cancer, today announced the presentation of data for CPX-351, its lead product candidate, at the American Association for Cancer Research (AACR) Annual Meeting in Philadelphia, PA on April 18-22, 2015.
Data were presented describing the effects of combining CPX-351 with traditional chemotherapy and novel molecularly targeted agents intended for use in treating AML and other blood cancers.
These studies have examined the impact of combining CPX-351 with approved anti-leukemia drugs such as fludarabine as well as novel molecularly targeted agents such as the Chk1 inhibitors MK-8776 and LY2603618. In both cases, the combined agents complemented each other's anti-leukemic properties, resulting in an enhanced overall effect.
When fludarabine and CPX-351 were exposed to leukemia cells, intracellular concentrations of cytarabine triphosphate (Ara-CTP) were increased by two to three fold. This is important since Ara-CTP is the active form of cytarabine that kills the leukemia cells. Chk1 inhibitors and CPX-351 synergized to induce increased DNA fragmentation and apoptosis, leading to increased (as high as 10-fold) leukemia cell kill in a number of AML lines as well as in AML patient blasts.
"Together, these results provide promising evidence that CPX-351 may combine favorably with a wide range of agents to achieve enhanced anti-leukemic effects against AML cells," said Lawrence Mayer, Ph.D., President and Chief Scientific Officer at Celator. "As we await the clinical data from our CPX-351 Phase 3 trial, we remain committed to exploring the expanded potential of CPX-351 as a foundation of care upon which additional agents can be added to further improve the outcomes of patients with AML as well as other blood cancers."

About Celator Pharmaceuticals, Inc.
Celator Pharmaceuticals, Inc., with locations in Ewing, N.J., and Vancouver, B.C., is a clinical stage biopharmaceutical company that is transforming the science of combination therapy, and developing products to improve patient outcomes in cancer. Celator's proprietary technology platform, CombiPlex®, enables the rational design and rapid evaluation of optimized combinations incorporating traditional chemotherapies as well as molecularly targeted agents to deliver enhanced anti-cancer activity. CombiPlex addresses several fundamental shortcomings of conventional combination regimens, as well as the challenges inherent in combination drug development, by identifying the most effective synergistic molar ratio of the drugs being combined in vitro, and fixing this ratio in a nano-scale drug delivery complex to maintain the optimized combination after administration and ensure its exposure to the tumor. Celator's pipeline includes lead product, CPX-351 (a liposomal formulation of cytarabine:daunorubicin) for the treatment of acute myeloid leukemia; CPX-1 (a liposomal formulation of irinotecan:floxuridine) for the treatment of colorectal cancer; a preclinical stage product candidate, CPX-8 (a hydrophobic docetaxel prodrug nanoparticle formulation), being studied by the National Cancer Institute's Nanotechnology Characterization Laboratory. The company is advancing the CombiPlex platform and broadening its application to include molecularly targeted therapies and epigenetic modulators.
