Neos Therapeutics Completes Resubmission of NDA for Cotempla XR-ODT for the Treatment of ADHD

DALLAS/FORT WORTH, Texas, Dec. 20, 2016 -- Neos Therapeutics, Inc. (NASDAQ:NEOS), a pharmaceutical company focused on developing, manufacturing and commercializing innovative extended-release (XR) products using its proprietary modified-release drug delivery and orally disintegrating tablet (ODT) technology platforms today announced that it has completed the resubmission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for Cotempla XR-ODT™, the Company’s methylphenidate extended-release orally disintegrating tablet, for the treatment of ADHD.

“Today marks an important milestone for Neos, as Cotempla XR-ODT is a key product candidate in our growing portfolio of patient-friendly treatment options for ADHD. If approved, Cotempla XR-ODT will provide a once-daily extended release profile in an ODT formulation of methylphenidate,” said Vipin K. Garg, Ph.D., President and CEO of Neos Therapeutics. “We recently submitted another NDA for our amphetamine XR oral suspension drug candidate, NT-0201. If approved, we expect to sell these ADHD products by the end of 2017 alongside Adzenys XR-ODT™. We look forward to offering a portfolio of innovative products for both of the stimulant medications that are most widely prescribed for the treatment of ADHD.”

In November 2015, Neos received a FDA-issued Complete Response Letter for Cotempla XR-ODT requiring that the Company conduct a bridging study to demonstrate bioequivalence between the clinical trial material and the to-be-marketed drug product, including an assessment of food effect, and to provide validation and three months of stability data. This resubmission follows the successful completion of the bioequivalence bridging study, and the validation and stability campaigns. This is a Class 2 resubmission, with a target six-month Prescription Drug User Fee Act (PDUFA) review period.

The NDA includes a Phase 3 clinical efficacy and safety study in children in a laboratory classroom setting. Treatment with Cotempla XR-ODT showed a statistically significant improvement in ADHD symptom control compared to placebo across the classroom day. Onset of effect was observed within one hour post-dose and persisted through 12 hours. No serious adverse events were reported during the study and the adverse event profile was consistent with the drug’s mechanism of action.¹ In addition, data from a pharmacokinetic study in children with ADHD was submitted.²

About ADHD

According to the Centers for Disease Control and Prevention, ADHD is one of the most common childhood disorders and can continue through adolescence and adulthood.³ In fact, ADHD is estimated to affect 5 percent of children and 2.5 percent of adults in the U.S.⁴ Symptoms include inattentiveness, hyperactivity and impulsiveness.⁴ These patterns of behavior are seen in many settings (school, home, work) and can impact performance and relationships.

Stimulant medications such as amphetamine and methylphenidate are the standard of care for treating ADHD, and extended-release (XR) formulations of these medications allow for once-daily dosing.⁵ Most of the existing treatment options are tablets or capsules, which need to be swallowed intact or in some cases sprinkled on certain foods or fluids and ingested immediately. Orally disintegrating tablets differ from traditional tablets and capsules in that they are designed to disintegrate in the mouth, rather than being swallowed whole.
