Axsome Therapeutics Receives FDA Clearance of IND for Phase 2/3 Trial of AXS-05 in Alzheimer’s Disease Agitation

NEW YORK, Jan. 03, 2017 (GLOBE NEWSWIRE) -- Axsome Therapeutics, Inc. (NASDAQ:AXSM), a clinical-stage biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, today announced that its Investigational New Drug Application (IND) for AXS-05 in the treatment of agitation in patients with Alzheimer’s disease (AD) has been cleared by the U.S. Food and Drug Administration (FDA). The IND clearance permits Axsome to proceed with its planned Phase 2/3 clinical trial of AXS-05 in this indication. Axsome anticipates commencing this trial in the first half of 2017.

“Agitation, including aggression, is seen in a significant percentage of patients with Alzheimer’s disease, leads to early nursing home placement, accelerates cognitive decline, and increases the risk of death,” said Herriot Tabuteau, M.D., Chief Executive Officer of Axsome Therapeutics. “We look forward to examining the potential of AXS-05 to treat this distressing condition for which there is currently no approved treatment. The successful filing and FDA clearance of this IND is a key milestone for Axsome and marks the second open IND for AXS-05.”

The planned Phase 2/3 trial is a multicenter, randomized, double-blind, placebo-controlled study to examine the efficacy and safety of AXS-05 in AD patients with agitation. Approximately 330 subjects will be randomly assigned to treatment with AXS-05, placebo, or bupropion, which is one of the components of AXS-05. The primary endpoint of the trial will be assessed using the Cohen-Mansfield Agitation Inventory.

About Agitation in Alzheimer’s Disease

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that manifests initially as forgetfulness advancing to severe cognitive impairment and memory loss. It afflicts an estimated 5 million individuals in the United States, a number that is anticipated to increase to approximately 14 million by 2050. In addition to cognitive decline, individuals diagnosed with AD typically experience behavioral and psychological symptoms including agitation which is reported in as many as 40% of patients. Agitation is characterized by emotional distress, aggressive behaviors, disruptive irritability, and disinhibition. Agitation in patients with AD has been associated with increased caregiver burden, decreased functioning, earlier nursing home placement, and increased mortality. There are currently no therapies approved by the FDA for the treatment of agitation in patients with AD.

About AXS-05

AXS-05 is a novel, oral, investigational drug product under development for the treatment of central nervous system (CNS) disorders. AXS-05 utilizes Axsome’s technology of combining bupropion and dextromethorphan. Dextromethorphan is an NMDA receptor antagonist, sigma-1 receptor agonist, and inhibitor of the serotonin and norepinephrine transporters. Bupropion serves to increase the bioavailability of dextromethorphan, and is a norepinephrine and dopamine reuptake inhibitor, and a nicotinic acetylcholine receptor antagonist. AXS-05 is an investigational drug product not approved by the FDA.
