Axsome Therapeutics Initiates ADVANCE-2 Phase 3 Trial of AXS-05 in Alzheimer’s Disease Agitation

NEW YORK, Sept. 08, 2022 (GLOBE NEWSWIRE) -- Axsome Therapeutics, Inc. (NASDAQ: AXSM), a biopharmaceutical company developing and delivering novel therapies for the management of central nervous system (CNS) disorders, announced that it has enrolled the first patient in the ADVANCE-2 trial of AXS-05, an investigational treatment for Alzheimer’s disease (AD) agitation.

ADVANCE-2 (Addressing Dementia via Agitation-Centered Evaluation-2) is a Phase 3, randomized, double-blind, placebo-controlled, multicenter, trial to assess the efficacy and safety of AXS-05 for the treatment of agitation associated with AD. Approximately 350 patients will be randomized in a 1:1 ratio to receive AXS-05 or placebo for 5 weeks. The primary efficacy measure is the Cohen-Mansfield Agitation Inventory (CMAI).

AXS-05 has been granted U.S. Food and Drug Administration (FDA) Breakthrough Therapy designation for the treatment of Alzheimer's disease agitation.

About Alzheimer’s Disease (AD) Agitation

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, and behavioral and psychological symptoms including agitation. AD is the most common form of dementia and afflicts an estimated 6 million individuals in the United States, a number that is anticipated to increase to approximately 14 million by 2050 [1]. Agitation is reported in up to 70% of patients with AD and is characterized by emotional distress, aggressive behaviors, disruptive irritability, and disinhibition [2]. Agitation in patients with AD has been associated with increased caregiver burden, decreased functioning, accelerated cognitive decline, earlier nursing home placement, and increased mortality [2-4]. There are currently no therapies approved by the FDA for the treatment of agitation in patients with AD.

About AXS-05

AXS-05 (dextromethorphan-bupropion) is a novel, oral, patent protected, investigational N-methyl-D-aspartate (NMDA) receptor antagonist with multimodal activity under development for the treatment of Alzheimer’s disease (AD) agitation and other central nervous system (CNS) disorders. AXS-05 utilizes a proprietary formulation and dose of dextromethorphan and bupropion, and Axsome’s metabolic inhibition technology, to modulate the delivery of the components. The dextromethorphan component of AXS-05 is an uncompetitive NMDA receptor antagonist, also known as a glutamate receptor modulator, and a sigma-1 receptor agonist. The bupropion component of AXS-05 serves to increase the bioavailability of dextromethorphan, and is a norepinephrine and dopamine reuptake inhibitor. AXS-05 is covered by a robust patent estate extending out at least to 2037-2040. AXS-05 has been granted FDA Breakthrough Therapy designation for the treatment of Alzheimer’s disease agitation. AXS-05 is not approved by the FDA for the treatment of AD agitation.
