Teva reports top-line results from final Phase III study of armodafinil (NUVIGIL®) in patients with major depression associated with bipolar I disorder

Teva Pharmaceutical Industries Ltd. (NYSE: TEVA) today announced top-line results of its final Phase III clinical study for armodafinil (NUVIGIL®) as adjunct therapy in adults with major depression associated with bipolar I disorder. The study reached statistical significance in several important secondary endpoints, such as responder rate and remission. However, it did not reach its primary endpoint –to determine whether armodafinil treatment (150mg per day) is more effective than placebo as adjunct therapy to mood stabilizers and/or atypical antipsychotics.

This study was the third of three, Phase III studies, all of which demonstrated improvements in patient response. However, based on an evaluation of the totality of results, Teva will not proceed with regulatory filings for armodafinil for the treatment of major depression associated with bipolar I disorder. There is no material impact to the Company.

“While this study demonstrated a numerical improvement, we are disappointed that armodafinil did not reach statistical significance. Teva remains committed to advancing science in serious conditions affecting the central nervous system.“ Said Michael Hayden, M.D., Ph.D., President of Global R&D and Chief Scientific Officer at Teva. “We will continue to focus on our current NUVIGIL® indications and we remain committed to improving wakefulness in adult patients with excessive sleepiness associated with shift work disorder, obstructive sleep apnea or narcolepsy.”
