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; and 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.
