NeurOp Receives FDA Orphan Drug Designation for NP10679 for Treatment of Subarachnoid Hemorrhage

Atlanta, GA – December 8, 2021NeurOp, Inc., a clinical-stage biotechnology company focused on neurological and psychiatric disorders, today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to the company’s investigational candidate NP10679 for the treatment of subarachnoid hemorrhage (SAH).

SAH is a life-threatening type of stroke caused by bleeding into the space surrounding the brain. In patients who experience SAH caused by a ruptured aneurysm, vasospasm producing ischemic damage occurs in over one-third of patients during the week following the event and often results in permanent disability or death.

The mechanism by which ischemia damages the brain involves overactivation of NMDA receptors. Ischemia also induces acidity of brain tissue. Together, these insights led NeurOp to develop NMDA receptor blockers with increased potency in acidic tissue. NeurOp’s lead compound NP10679 is a highly selective antagonist for NMDA receptors and has greater potency in acidic conditions. These properties will enable it to provide neuroprotection against ischemic injury caused by vasospasm in SAH with fewer negative side effects than currently available NMDA inhibitors and other treatments.

“NP10679 demonstrated safety, tolerability and positive pharmacokinetics in our Phase 1 studies that make it an attractive candidate for prophylactic treatment following SAH,” said James McNamara, M.D., Executive Chairman of NeurOp. “Based on its encouraging profile, we look forward to commencing a Phase 2 clinical trial of NP10679 for SAH in 2023.”

The FDA Office of Orphan Products Development grants orphan drug designation to investigational drugs and biologics intended for the treatment, diagnosis or prevention of rare diseases, which are defined as those that affect fewer than 200,000 people in the U.S. The program provides certain benefits that include tax credits and application fee waivers designed to offset some development costs, as well as seven-year marketing exclusivity to sponsors of approved orphan products.

About NP10679
NeurOp is developing NP10679 as a subunit-specific NMDA receptor inhibitor for CNS disorders. NMDA receptors are activated by the neurotransmitter glutamate, the predominant excitatory transmitter in the brain. Several neurological disorders, including pain, treatment-resistant depression and brain damage resulting from acute brain injury, such as stroke or SAH, are associated with overactivity of these receptors. NP10679 is selective for a specific NMDA subtype, GluN2B, and has increased potency in acidic conditions. Its enhanced selectivity and disease context-dependent target engagement may provide neuroprotection with fewer negative side effects than currently available NMDA inhibitors.

About NeurOp, Inc.

NeurOp Initiates Phase 1 Clinical Trial of NMDA Receptor Inhibitor NP10679

NeurOp, Inc., a clinical-stage biotechnology company, today announced the initiation of a Phase 1 clinical trial of NP10679, a highly potent and selective GluN2B subunit-specific NMDA (N-methyl-D-aspartate) receptor inhibitor. NeurOp is investigating NP10679 for several neurological disorders that are associated with over-activity of these receptors.

The randomized, placebo-controlled, single ascending dose study will assess the safety, pharmacokinetics and pharmacodynamics of NP10679 in healthy volunteers. The study is being conducted in collaboration with Pharmaron (Baltimore) and is currently enrolling subjects in the United States. Data collected from the study will inform dose and schedule for further development of NP10679 for potential use in severe pain and the prevention of ischemic damage following subarachnoid hemorrhage (SAH).

Certain areas of the brain become acidified by metabolic insufficiency or increased neuronal activity. This condition or “context” exists in severe pain and SAH and may also exist in brain areas that are undergoing seizures or involved in nicotine or opioid addiction.

“NP10679 is a first-in-class therapy as a context-dependent NMDA receptor inhibitor,” said NeurOp’s Chief Scientific Officer, Robert Zaczek, PhD. “Preclinical data demonstrate that NP10679 is different from other NMDA therapies, because of its selectivity, safety profile and potency at low pH, a condition found in a number of central nervous system disorders.”

“We have achieved a significant milestone for NeurOp now that NP10679 has advanced to the clinic,” said James McNamara, MD, Executive Chairman at NeurOp. “We look forward to moving this compound through clinical development and are particularly encouraged by its potential as a treatment for severe pain. With the opioid epidemic facing the nation, the need for effective and safe medications for severe pain is greater than ever.”

NP10679 is bioavailable either orally or by IV, and it is currently being evaluated in this study by the IV route. An IND for NP10679 was opened in 2016.
