CL-108 is a novel, bi-layered tablet containing 7.5 mg of hydrocodone and 325mg of acetaminophen with 12.5mg of immediate-release promethazine.

The studies will evaluate the safety and efficacy of CL-108, the first of its kind intended to treat moderate to severe acute pain while reducing nausea and vomiting, common side effects of opioids. . One study is a randomized, double-blind, placebo- and active-controlled trial conducted in patients following bunionectomy surgery at 3 major research centers in the United States. The second study is being conducted at 17 research centers across the country in patients suffering moderate to severe acute pain from osteoarthritis of the knee or hip.

“Following the announcement of our collaboration with Daiichi Sankyo, the initiation of these two clinical trials marks a critical moment in our timeline for Charleston Laboratories,” said Mr. Paul Bosse, President and CEO at Charleston Laboratories. “As a result of the planning and hard work by our Chief Scientific Officer, Dr. Bernard Schachtel, and his dedicated research staff, Charleston is already conducting the final studies to support the NDA for CL-108, which is targeted for filing with the FDA later next year.”

The results of the first Phase 3 trial were published in abstract form (“Demonstration of the safety and efficacy of CL-108 for moderate-to-severe pain with reduction of opioid-induced nausea and vomiting”) in the April 2014 issue of the Journal of Pain, the official journal of the American Pain Society.i The study was terminated early by an external Data Safety Monitoring Board because of the significant (p < 0.01) evidence of the safety and efficacy of CL-108.
