VFMCRP announces U.S. Court upholds validity of Velphoro® patent

U.S. District Court for the District of Delaware rules Teva Pharmaceuticals infringes VFMCRP patent

Disputes with all other Abbreviated New Drug Application (ANDA) filers regarding Velphoro® have been settled

ST. GALLEN, SWITZERLAND – 22 August 2022 – Vifor Fresenius Medical Care Renal Pharma (VFMCRP) today announced that the U.S. District Court for the District of Delaware issued a judgment in VFMCRP’s favor regarding U.S. patent no. 9,561,251 which covers the formulation for Velphoro® (sucroferric oxyhydroxide). The decision, subject to appeal, holds that the generic sucroferric oxyhydroxide product proposed by Teva Pharmaceuticals USA, Inc., in its Abbreviated New Drug Application (ANDA) will infringe the Velphoro® U.S. patent no. 9,561,251, which expires in July 2030 (including pediatric extension). Currently, Velphoro® is protected by multiple Orange Book listed patents which expire between May 2029 and May 2035.

A further ANDA patent infringement lawsuit against Teva based on patents no. 10,682,376, no. 10,695,367 and no 11,013,761, all expiring in May 2029 remains pending.

VFMCRP has previously settled disputes with Lupin Pharmaceuticals, Inc and Annora Pharma Pvt. Ltd. which had filed ANDAs to market a generic version of Velphoro®.
