FDA Issues Complete Response on Combo Pain Drug
FDA has issued Charleston Laboratories and Daiichi Sankyo a complete response letter (CRL) on their NDA for CL-108 (hydrocodone, acetaminophen, promethazine), an investigational treatment for managing pain severe enough to require an opioid analgesic while preventing or reducing the associated opioid-induced nausea and vomiting when alternative treatments for pain are inadequate. “The CRL stated that the NDA in its present form was not approved and provided guidance on information needed to resolve matters identified,” the companies say, adding that they intend to work closely with FDA to address the points raised in the letter. Charleston Labs says CL-108 is a novel bi-layered tablet containing 12.5 mg of immediate release promethazine with a modified release of 7.5 mg of hydrocodone and 325 mg of acetaminophen.
