Stock Update (NASDAQ:CPXX): Celator Pharmaceuticals Inc Receives Allowance of Expanded U.S. Claims on CombiPlex® Technology

Celator Pharmaceuticals Inc (NASDAQ:CPXX) announced that it was given a notice of allowance of claims by the United States Patent and Trademark Office for the patent “Compositions for Delivery of Drug Combinations.”  This patent covers the Company’s proprietary CombiPlex technology, and the allowed claims increase the scope of drug delivery vehicles covered by the patent.

Celator recently announced the successful application of its proprietary CombiPlex technology to drug combinations incorporating molecularly targeted agents (MTAs), where marked improvements in pharmacokinetics, tolerability, efficacy and drug ratio-dependent efficacy were achieved. The chemical features of many MTAs require drug carriers capable of co-encapsulating hydrophobic drugs, and the allowed claims now broadly cover micelles, polymer nanoparticles, polymer microparticles, polymer-lipid hybrid systems and derivatized single chain polymers. These types of drug carriers are often used to encapsulate hydrophobic drugs for systemic delivery.

“This is an important development for our CombiPlex platform,” said Dr. Lawrence Mayer, president and chief scientific officer at Celator. “The repertoire of drug carriers now covered by the patent claims, positions Celator for leadership in a space where evidence is mounting that improved delivery of MTA combinations could overcome significant challenges experienced with conventional formulations of these agents. We expect this will strengthen our ability to pursue R&D collaborations with biopharmaceutical companies.” (Original Source)
