Summary for Patent: 7,709,444

Title:	Echinocandin pharmaceutical formulations containing micelle-forming surfactants
Abstract:	Pharmaceutical formulations are described comprising an echinocandin compound or echinocandin/carbohydrate complex and a pharmaceutically acceptable micelle-forming surfactant in a non-toxic aqueous solvent such that the solubilization of the echinocandin compound is optimized and the ability to freeze-dry the solution is maintained. Both the solution and freeze-dried formulations have increased stability. A bulking agent, tonicity agent buffer and/or a stabilizing agent may optionally be added to the formulations to further enhance the stability of the formulation.

For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
