Novartis to Appeal CAFC’s ‘Unprecedented’ U-Turn in Ruling on Multiple Sclerosis Drug Claims to SCOTUS

Novartis Pharmaceuticals announced today that it will appeal the U.S. Court of Appeals for the Federal Circuit’s (CAFC’s) June decision invalidating its patent for a dosing regimen for its multiple sclerosis drug Gilenya to the U.S. Supreme Court, after the CAFC denied its request to rehear the case. The CAFC in June vacated a different three-judge panel’s January opinion upholding Novartis’ U.S. Patent No. 9,187,405. In the original ruling, Chief Judge Moore had dissented from the majority; in the rehearing, Moore authored the opinion vacating the January decision, with Judge Linn dissenting.

PTAB ends Kyle Bass IPRs targeting Acorda patents on Ampyra MS treatment with no findings of obviousness

A panel of administrative patent judges (APJs) at the Patent Trial and Appeal Board (PTAB) issued a final written decision ending a series of inter partes review (IPR) proceedings targeting patents covering a popular multiple sclerosis (MS) treatment developed and sold by Ardsley, NY-based Acorda Therapeutics (NASDAQ:ACOR). The decision strengthens the patent portfolio covering Acorda’s Ampyra pharmaceutical even as competition from generic manufacturers has ramped up in recent months. The IPRs, instituted after petitions from the Kyle Bass-backed Coalition for Affordable Drugs (ADORCA), targeted four patents listed in the U.S. Food and Drug Administration’s (FDA) Orange Book.

Patent Granted on Long-Acting Drug for Multiple Sclerosis

The conjugates covered by this patent could enable less frequent and better tolerated dosing of one of the most widely used treatments worldwide for relapsing-remitting multiple sclerosis, interferon-beta-1b. The invention described in the European Patent relates to methods for the preparation of conjugates of poly(ethylene glycol), and derivatives thereof, with interferon-beta-1b. Compared to the corresponding unconjugated bioactive components, the conjugates of the invention have increased stability (i.e., longer shelf life and longer half-lives in vivo). In addition, compared to conjugates of the same bioactive component prepared with polymer chains that are attached randomly to solvent-accessible sites along the polypeptide chains, the conjugates of the invention have increased receptor-binding activity and increased potency.
