Perrigo Co. PLC said Promius Pharma LLC filed a lawsuit to assert patents for its psoriasis treatment Sernivo.
Perrigo is looking to market a generic version of Sernivo, or betamethasone dipropionate, spray, in the U.S. The drug, which is used to treat mild-to-moderate plaque psoriasis in adults, generated annual market sales of about $16 million for the year ended March, according to IQVIA data cited by Perrigo.
Promius Pharma, a U.S.-based unit of Indian pharmaceutical company Dr. Reddy's Laboratories Ltd., filed the patent litigation in the U.S. District Court for the Eastern District of Texas.
Perrigo makes over-the-counter healthcare products, infant formulas, branded OTC products, and generic pharmaceutical products.
