ALLEGAN, Mich. Perrigo on Wednesday announced that it has acquired the exclusive U.S. store brand rights to sell and distribute dextromethorphan polistirex extended-release suspension cough suppressant -- the generic version of Reckitt Benckiser's Delsym -- from Tris Pharma.
Tris believes it has a first-to-file ANDA application for the generic that can entitle it to 180 days of generic exclusivity upon approval. Tris and Reckitt Benckiser are currently engaged in Paragraph IV/Hatch-Waxman litigation over the Tris ANDA filing. Under the agreement Perrigo and Tris will share profits, and Perrigo will pay Tris certain milestone payments.
Delsym had annual sales of approximately $125 million dollars, Perrigo reported, citing SymphonyIRI data.
