SPN-817 is an investigational small molecule being developed for epilepsy, including focal onset seizures and treatment-resistant epilepsy. It is currently in Phase 2 clinical development and is not yet approved by the FDA. The drug is being studied in adult patients with these seizure disorders.
SPN-817 targets acetylcholinesterase (AChE), an enzyme involved in neurotransmission. By inhibiting this enzyme, the drug may modulate cholinergic signaling in the brain, which is being investigated as a potential mechanism for reducing seizure activity in epilepsy patients.
SPN-817 is being developed by Supernus Pharmaceuticals, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol SUPN. The company is conducting Phase 2 clinical trials to evaluate the drug's safety and efficacy in treating epilepsy and focal onset seizures.
SPN-817 is currently in Phase 2 clinical development. It is being evaluated in multiple Phase 2 trials, including a double-blind, placebo-controlled study in adults with focal onset seizures and an open-label extension study. The drug is investigational and has not received FDA approval.
SPN-817 is being studied in several clinical trials. NCT05518578 is a Phase 2 safety and tolerability study in adults with treatment-resistant epilepsy. NCT06798896 is a Phase 2 double-blind, placebo-controlled study in focal onset seizures. NCT07141329 is an open-label extension study in focal onset seizures. A Phase 1 bioavailability study (NCT05102552) has been completed.
SPN-817 is a distinct investigational compound with a unique mechanism of action targeting acetylcholinesterase. It is not the same as other marketed epilepsy drugs, which typically work through different pathways such as sodium channels or GABA receptors. SPN-817 is being developed specifically for treatment-resistant epilepsy and focal onset seizures.
