Supernus is a specialty pharmaceuticals company focused on developing and commercializing products for the treatment of central nervous system, or CNS, diseases. The company's lead products, Oxtellar XR® and Trokendi XR®, are for the treatment of epilepsy. Supernus is also developing several product candidates to address large market opportunities in psychiatry, including SPN-810 for the treatment of Impulsive Aggression in patients with attention deficit hyperactivity disorder (ADHD) and SPN-812 for the treatment of ADHD.

Supernus has two products for the treatment of epilepsy: Oxtellar XR®, launched in the first quarter of 2013, and Trokendi XR®, launched in the third quarter of 2013.

Oxtellar XR® is a novel, oral, once-daily, extended-release formulation of oxcarbazepine. Oxcarbazepine was developed by Novartis Pharmaceuticals Corporation and launched under the brand name Trileptal®.

Oxcarbazepine is an active voltage-dependent sodium channel blocker that, despite its effectiveness in treating epilepsy, is associated with many side effects that tend to limit its use, such as dizziness, double vision, somnolence, nausea, and vomiting.

Trokendi XR® is a novel, oral, extended-release, once-daily formulation of topiramate for the treatment of epilepsy. Trokendi XR® delivers topiramate, one of the most effective anti-epilepsy drugs, which was developed by Johnson & Johnson and marketed under the brand name Topamax®.

Topiramate as an anti-epileptic drug is indicated for monotherapy and adjunctive therapy of epilepsy, as well as for the treatment of migraine.

Side effects associated with topiramate, which have tended to limit its use, include dizziness, fatigue, somnolence, and slowing of certain cognitive functions.

Oxtellar XR® and Trokendi XR® are designed to improve patient compliance compared to the current immediate-release products that are taken multiple times per day.

Oxtellar XR® and Trokendi XR® deliver lower peak plasma concentrations and lower input rate over an extended time period, resulting in smoother and more consistent blood levels of oxcarbazepine or topiramate during the day compared to immediate-release products. Moreover, Oxtellar XR® and Trokendi XR® avoid blood level fluctuations that can be associated with many of the side effects or breakthrough seizures that patients can suffer from when taking immediate-release products.
