In other Pfizer news, the Court of Appeal of The Hague in the Netherlands upheld Pfizer’s basic patent covering atorvastatin, the active ingredient in Lipitor. The decision means Ranbaxy is unable to launch a generic version of the drug before Lipitor’s basic patent (EP 247,633) expires in November 2011. Ranbaxy can seek to appeal the decision to the Supreme Court of the Netherlands.
Nottingham, UK (Feb. 20)-Upperton, a biotechnology company specializing in spray drying and particle technologies, will collaborate with Novozymes (Bagsvaerd, Denmark) for commercializing the companies’ jointly-owned “rP-nano” technology, a targeted drug delivery system that uses the natural binding properties of recombinant protein nanoparticles to enhance drug and gene bioavailability. The rP-nano technology can produce nanoparticles from peptides and proteins, including monoclonal antibodies and enzymes, without denaturation. Under the terms of the agreement, Upperton will use rP-nano technology to generate nanoparticles from recombinant proteins expressed in Novozymes’ proprietary, yeast-based expression system. The rP-nano technology can generate nanoparticles of 10–120 nm and be optimized for permeability and retention, according to Upperton. The nanoparticles produced through this process retain the natural binding properties of the recombinant proteins from which they are made and bind to specific cell types to enable more targeted drug delivery and improved bioavailability, according to the company.
Winnersh, UK (Feb. 20)-Vernalis made an early settlement on a $56-million loan due to Endo Pharmaceuticals. The loan was originally due for repayment in August 2009.

According to a company release, the early loan settlement and the restructuring were triggered by FDA’s recent nonapproval of the company’s supplementary NDA submission for its product “Frova” for the treatment of menstrual migraine.
