Alvogen subsidiary, Lotus Pharmaceuticals (“Lotus”), today announced that Celgene filed a suit on 6 September 2017 in the United States District Court for the District of New Jersey. The lawsuit was filed under provisions of the Hatch-Waxman Act, resulting in a stay of final Food and Drug Administration (FDA) approval of Lotus’ Abbreviated New Drug Application (ANDA) for up to 30 months from the date the plaintiffs, Celgene, received notice of Lotus' ANDA filing or until final resolution of the matter before the court, whichever occurs sooner, subject to any other exclusivities.
Lotus filed an ANDA with the United States FDA seeking regulatory approval to market a generic version of Revlimid®. Lotus’ ANDA included a paragraph IV certification with respect to the patents listed in the FDA’s listing of Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”).
Lotus’ ANDA product is a generic version of Celgene’s Revlimid® 2.5, 5, 10, 15, 20 and 25 mg, which is indicated for the treatment of several hematological malignancies including multiple myeloma. The product was developed by Lotus pharmaceuticals in Taiwan.
