CUPERTINO, Calif., Oct. 1, 2012 /PRNewswire/ -- NextWave Pharmaceuticals, an emerging specialty pharmaceutical company, announced FDA approval of Quillivant XR(methylphenidate hydrochloride) for extended-release oral suspension, CII. Quillivant XR is approved for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). Quillivant XR is the first once-daily, extended-release liquid methylphenidate available for patients with ADHD.
"The approval of Quillivant XR fills a void that has long existed in the treatment of ADHD," said Ann Childress, M.D., President of the Center for Psychiatry and Behavioral Medicine, Las Vegas, who was an investigator in the Quillivant XR laboratory classroom study. "We routinely see the struggles of patients who have difficulty swallowing pills or capsules. Having the option of a once-daily liquid will help alleviate some of these issues while still providing the proven efficacy of methylphenidate for 12 hours after dosing."
The efficacy of Quillivant XR was evaluated in a randomized, double-blind, placebo-controlled, crossover, multicenter, laboratory classroom study of 45 children with ADHD. There was an open-label dose optimization period (four to six weeks) with an initial 20mg dose of Quillivant XR once daily in the morning. The dose was titrated weekly in 10 or 20mg increments until an optimal dose or maximum dose of 60mg per day was reached. Patients then entered a two-week double-blind, crossover treatment of the individually optimized dose of Quillivant XR or placebo.
At the end of each week, trained observers evaluated the attention and behavior of the patients in a laboratory classroom using the SKAMP (Swanson, Kotkin, Agler, M-Flynn and Pelham) rating scale. Quillivant XR significantly improved ADHD symptoms compared to placebo at the primary endpoint of four hours post-dose, and in a secondary analysis, showed significant improvement at every time point measured, from 45 minutes to 12 hours after dosing.
"We are pleased with the FDA's approval of Quillivant XR and believe it will address an important need for many patients with ADHD and their caregivers," said Jay Shepard, President and CEO of NextWave Pharmaceuticals. "We are eager to enter into the ADHD market and believe the unique liquid formulation of Quillivant XR -- which was developed in conjunction with NextWave's technology and manufacturing partner Tris Pharma -- will provide another treatment option for patients with ADHD."
Quillivant XR is expected to become available in pharmacies in January 2013. Quillivant XR was developed using Tris Pharma's patent protected drug delivery platform.
