Axsome Therapeutics Initiates ACCORD Phase 3 Trial of AXS-05 in Alzheimer’s Disease Agitation
Axsome Therapeutics has initiated the ACCORD Phase 3 trial to evaluate AXS-05 for treating Alzheimer’s disease agitation. AXS-05, an investigational NMDA receptor antagonist, aims to address a significant unmet need as no treatments are currently approved for this condition. The trial will include an open-label stabilization phase followed by a randomized double-blind period. Topline results are expected in late 2022, supported by previous positive findings from the ADVANCE trial. The FDA has granted Breakthrough Therapy designations for AXS-05, underscoring its potential impact.
- Initiation of Phase 3 ACCORD trial for AXS-05 targeting Alzheimer’s disease agitation.
- AXS-05 has received Breakthrough Therapy designation from the FDA for this indication.
- Previous positive results from the ADVANCE trial bolster confidence in AXS-05’s effectiveness.
- None.
ACCORD is the second pivotal trial of AXS-05 in Alzheimer’s disease agitation
No treatments are currently approved for Alzheimer’s disease agitation
NEW YORK, Dec. 31, 2020 (GLOBE NEWSWIRE) -- Axsome Therapeutics, Inc. (NASDAQ: AXSM), a biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, announced the initiation of the ACCORD (Assessing Clinical Outcomes in Alzheimer’s Disease Agitation) study, a Phase 3, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of AXS-05 in the treatment of Alzheimer’s disease (AD) agitation. AXS-05 (45 mg dextromethorphan-105 mg bupropion modulated delivery tablet) is a novel, oral, investigational NMDA receptor antagonist with multimodal activity. There is currently no approved treatment for AD agitation.
ACCORD is being conducted using a randomized-withdrawal design, in which all patients are first treated with open-label AXS-05, with the patients experiencing a treatment response being subsequently randomized in a double-blind fashion to continued treatment with AXS-05 or to switch to placebo. Patients completing the ACCORD trial will be eligible to enter an open-label safety extension trial. Initiation of the safety extension trial is expected imminently. Topline results from the ACCORD trial are anticipated in the second half of 2022.
“Initiation of the ACCORD Phase 3 trial in Alzheimer’s disease agitation continues the expedited clinical development of AXS-05 for this serious condition. The potential for AXS-05, with its unique pharmacological profile, in this indication is supported by the positive results in our completed pivotal ADVANCE trial,” said Herriot Tabuteau, MD, Chief Executive Officer of Axsome. “Alzheimer’s disease agitation is a prevalent and debilitating condition that is associated with earlier nursing home placement, accelerated progression to severe dementia, and increased risk of death. There are currently no approved treatments for Alzheimer’s disease agitation. If successfully developed, AXS-05 has the potential to address this high unmet need and significantly improve the lives of patients and their caregivers.”
Initiation of the ACCORD Phase 3 trial follows a Breakthrough Therapy meeting with the U.S. Food and Drug Administration (FDA), announced in August, to discuss the development plan for AXS-05 in AD agitation. Results of the meeting confirmed the pivotal status of the previously completed ADVANCE trial of AXS-05 in AD agitation. The meeting followed the receipt in June of Breakthrough Therapy designation from the FDA for AXS-05 for the treatment of AD agitation, the second Breakthrough Therapy designation received by Axsome for AXS-05. The designation was supported by the positive results of the ADVANCE trial. A Breakthrough Therapy designation is granted to potentially expedite development and review timelines for a promising investigational medicine when preliminary clinical evidence indicates it may demonstrate substantial improvement on one or more clinically significant endpoints over available therapies for a serious or life-threatening condition.
About the ACCORD Trial
ACCORD (Assessing Clinical Outcomes in Alzheimer’s Disease Agitation) is a Phase 3, randomized, double-blind, multicenter, placebo-controlled, trial to evaluate the efficacy and safety of AXS-05 in patients with Alzheimer’s disease (AD) agitation. Enrolled patients will first enter a 9-week, open-label stabilization period, during which they will be treated with AXS-05 and monitored for a treatment response based on the Cohen-Mansfield Agitation Inventory (CMAI). Patients who experience a treatment response during the stabilization period will then be randomized into the double-blind treatment period, in a 1:1 ratio, to continue treatment with AXS-05 or to switch to placebo, for up to 26 weeks or until a relapse of agitation occurs. The primary endpoint will be the time from randomization to relapse. Assessments will include the CMAI, clinician- and caregiver-rated scales, and safety parameters.
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
About AXS-05
AXS-05 (dextromethorphan-bupropion modulated delivery tablet) is a novel, oral, patent-protected, investigational NMDA receptor antagonist with multimodal activity under development for the treatment of major depressive disorder 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 N-methyl-D-aspartate (NMDA) receptor antagonist, also known as a glutamate receptor modulator, which is a novel mechanism of action, meaning it works differently than currently approved therapies for major depressive disorder. The dextromethorphan component of AXS-05 is also a sigma-1 receptor agonist, nicotinic acetylcholine receptor antagonist, and inhibitor of the serotonin and norepinephrine transporters. The bupropion component of AXS-05 serves to increase the bioavailability of dextromethorphan, and is a norepinephrine and dopamine reuptake inhibitor, and a nicotinic acetylcholine receptor antagonist. AXS-05 is covered by more than 93 issued U.S. and international patents which provide protection out to 2040. AXS-05 has been granted U.S. Food and Drug Administration Breakthrough Therapy and Fast Track designations for Alzheimer’s disease agitation. AXS-05 is not approved by the FDA.
