ROCKVILLE, Md., Oct. 22, 2012 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq:SUPN), a specialty pharmaceutical company, received approval from the Food & Drug Administration (the "FDA") for Oxtellar XR , a novel once-daily extended release formulation of oxcarbazepine (formerly known as SPN-804). The approval letter states that the FDA has completed its review of the application and that Oxtellar XR is approved effective October 19, 2012 for use as recommended in the agreed-upon labeling. The FDA granted a waiver for the pediatric study requirement for ages birth to one month and a deferral for submission of post-marketing assessments for children 1 month to 6 years of age. The post-marketing pharmacokinetic assessments are due in 2016 followed by clinical assessments in 2021. "This is excellent news for Supernus and patients with epilepsy. We are very excited for having obtained two NDA approvals since our IPO in May of 2012; tentative approval on Trokendi XR ™ received in June and now final approval on Oxtellar XR. We are committed to the epilepsy community and very much look forward to making our products available to patients, " said Jack Khattar, Chief Executive Officer, President and Director of Supernus. "This approval represents a significant milestone for Supernus in realizing its vision of becoming a leading CNS specialty pharmaceutical company. We will now focus on completing the build-out of our commercial organization including, hiring, training and deploying our field sales force to launch Oxtellar XR in the first quarter of 2013. I would like to take this opportunity to thank all Supernus employees for a remarkable achievement in developing and advancing two NDAs in a relatively short period of time by industry standards. Also, I would like to thank our advisors and clinical investigators for their assistance in completing the clinical development of Oxtellar XR. The approval of Oxtellar XR adds to our proven and long track record of developing novel and differentiated products using our technologies and expertise," added Jack Khattar.
