The US Court of Appeals for the Federal Circuit (CAFC) has denied its petition to rehear the negative decision regarding the validity of US Patent No 9,187,405, covering a dosing regimen for 0.5mg of its blockbuster multiple sclerosis drug Gilenya (fingolimod), Swiss pharma giant Novartis (NOVN: VX) announced this morning.
Novartis plans to file a petition seeking further review of the CAFC’s decision with the US Supreme Court. Gilenya, one of Novartis’ top-selling therapies, generated around $2.8 billion sales last year.
In August 2020, the US District Court for the District of Delaware issued a favorable decision and a permanent injunction was granted against Chinese drugmaker HEC Pharma (HKG: 1558) until the expiration of the ’405 patent in December 2027 (including pediatric exclusivity). HEC Pharma was the only remaining Abbreviated New Drug Application (ANDA) filer challenging this patent.
