The development program which will be referred to as SPN-817 will utilize a novel synthetic form of huperzine A which is a potent acetyl cholinesterase inhibitor with pharmacological activities in CNS conditions such as epilepsy. SPN-817 will have a new chemical entity status (NCE) in the U.S. market, and Supernus expects to have significant IP protecting this product candidate through its own research and development efforts as well as the in-licensed IP.
SPN-817 represents a novel mechanism of action for an anticonvulsant. Development of SPN-817 will initially focus on the drug’s anticonvulsant activity that has been shown in preclinical models for partial seizures and Dravet Syndrome. It increases cortical acetylcholine and readily crosses the blood brain barrier showing an increase in gamma-aminobutyric acid (GABA), a seizure inhibitor, in the cortical region of the brain. In a predictive preclinical seizure model, huperzine A demonstrated 57 times more potency than levetiracetam, a leading anti-epilepsy drug.
Supernus will focus on completing and optimizing the synthesis process of the drug and the development of a novel dosage form. Given the potency of huperzine A, a novel extended release oral dosage form is critical to the success of this program because initial studies with immediate release formulations of non-synthetic huperzine A have shown dose-limiting serious side effects.
Supernus plans on studying SPN-817 initially in catastrophic pediatric epilepsy disorders such as Dravet Syndrome. A Phase I proof-of-concept trial is currently underway in adult patients with refractory complex partial seizures to study the safety and pharmacokinetics profile of a new extended release formulation.
"Supernus, with its strong presence in epilepsy and its proven technologies and research and development capabilities, represents an ideal partner for us. Huperzine A has a novel mechanism of action that represents a new approach for the treatment of epilepsy. We look forward to working with Supernus and progressing SPN-817 in the clinic, and eventually to its availability to patients," said Dr. Collins.
"We are excited to add SPN-817 to our portfolio as part of our long term growth strategy. It represents a strong strategic fit with Oxtellar XR and Trokendi XR in neurology. We are committed to epilepsy patients and to bringing to them novel alternative treatment options," said
