Cephalon Provides Clinical Update on Phase II Study of NUVIGIL as an Adjunctive Therapy in Adults with Schizophrenia
FRAZER, Pa., June 2 /PRNewswire-FirstCall/ — Cephalon, Inc. (Nasdaq: CEPH) today announced that the primary endpoint was not met in a Phase II clinical trial that examined NUVIGILÃ‚® (armodafinil) Tablets [C-IV] as an adjunctive therapy for the treatment of the negative symptoms of schizophrenia, which include problems with motivation and emotional withdrawal. The analysis of the data showed that treatment with armodafinil did not lessen the severity of the negative symptoms of schizophrenia compared to placebo in the 24-week study. As a result of the outcome of this trial, Cephalon has decided not to move forward with this clinical program.
The trial was designed to evaluate whether armodafinil treatment (150, 200, or 250 mg/day) was more effective than placebo treatment as an adjunctive therapy to antipsychotic medication in alleviating the negative symptoms of schizophrenia, as assessed by the primary outcome measure of the Positive and Negative Syndrome Scale. Although an interim analysis showed a trend towards a positive dose dependent treatment effect, it was not statistically significant and not maintained in the final analysis of all patients. Armodafinil was generally well tolerated in the study and the side effects were consistent with the known safety profile. Results of this study will be presented at a future medical meeting.
“While we are disappointed that the results of this study did not demonstrate a benefit for this patient population, Cephalon remains committed to the NUVIGIL clinical development plan,” said Dr. Lesley Russell, Chief Medical Officer at Cephalon. “We are continuing our discussions with the agency on our application for excessive sleepiness associated with jet lag disorder and Phase III trials are on track evaluating armodafinil in bipolar depression and excessive sleepiness resulting from traumatic brain injury.”
NUVIGIL is the longer-lasting isomer of modafinil. It is indicated to improve wakefulness in patients with excessive sleepiness associated with treated obstructive sleep apnea (OSA), shift work disorder (SWD), or narcolepsy. NUVIGIL is not approved as a treatment for jet lag disorder, bipolar depression, traumatic brain injury, or their associated symptoms. The NUVIGIL (armodafinil) label includes a bolded warning for serious or life-threatening rash, including Stevens-Johnson Syndrome, that has been reported in adults in association with the use of armodafinil and in adults and children in association with the use of modafinil, a racemic mixture of S and R modafinil (the latter is armodafinil, the active ingredient in NUVIGIL). NUVIGIL is not approved for use in pediatric patients for any indication.
The most common adverse events in controlled clinical trials (five percent or greater) were headache, nausea, dizziness, and insomnia. Full prescribing information for NUVIGIL is available at http://www.nuvigil.com/.
