NEW YORK, June 07, 2019 (GLOBE NEWSWIRE) --  Axsome Therapeutics, Inc. AXSM, a clinical-stage biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, is providing the following update on the Company's continued progress at its Annual Meeting of Stockholders being held today:

AXS-05

AXS-05 (dextromethorphan/bupropion) is Axsome's novel, oral, investigational NMDA receptor antagonist with multimodal activity being developed for the following indications: treatment resistant depression (TRD), major depressive disorder (MDD), Alzheimer's disease (AD) agitation, and smoking cessation. AXS-05 has been granted U.S. Food and Drug Administration (FDA) Breakthrough Therapy designation for the treatment of MDD and Fast Track designations for the treatment of TRD and for the treatment of AD agitation.

Depression

• Axsome continues to expect topline results from the ongoing Phase 3 STRIDE-1 trial of AXS-05 in TRD in the second half of 2019.
  
  
• Axsome is on track to initiate its planned placebo-controlled Phase 3 trial of AXS-05 in MDD this quarter with topline results anticipated in the second half of 2019.
  
  
• An NDA filing for AXS-05 in the treatment of MDD is targeted for 2020. 

Alzheimer's Disease Agitation

• Axsome remains on track to report topline results from the ongoing Phase 2/3 ADVANCE-1 trial of AXS-05 in agitation associated with Alzheimer's disease in the first half of 2020.

AXS-07

AXS-07 (MoSEIC™ meloxicam/rizatriptan) is Axsome's novel, oral, investigational medicine with distinct dual mechanisms of action being developed for the acute treatment of migraine.

• Based on the continued faster-than-expected enrollment in the MOMENTUM Phase 3 trial of AXS-07 in the acute treatment of migraine, Axsome continues to anticipate topline results from this trial in the second half of 2019. MOMENTUM is being conducted pursuant to an FDA Special Protocol Assessment (SPA).

AXS-12

AXS-12 (reboxetine) is Axsome's novel, oral, potent and highly selective norepinephrine reuptake inhibitor being developed for the treatment of narcolepsy. AXS-12 has been granted Orphan Drug Designation by the FDA for the treatment of narcolepsy.

• Based on current enrollment trends, Axsome now anticipates topline results from the CONCERT Phase 2 trial of AXS-12 in narcolepsy in the second half of 2019 versus previous guidance of the second quarter of 2019.

Financial Update

• Axsome believes that its current cash will be sufficient to fund the Company's anticipated operations, based on its current operating plans, into at least the first quarter of 2021, or approximately 1 year beyond the readout of all of the above ongoing and planned clinical trials.
  
  
• Axsome currently does not anticipate future equity financings prior to the readout from its Phase 3 trials.

Anticipated Clinical Trial Readouts

• Phase 3 STRIDE-1 trial of AXS-05 in TRD, topline data (2H 2019)
  
  
• Phase 3 placebo-controlled trial of AXS-05 in MDD, topline data (2H 2019)
  
  
• Phase 3 trial of AXS-07 in the acute treatment of migraine, topline data (2H 2019)
  
  
• Phase 2 trial of AXS-12 in narcolepsy, topline data (2H 2019)
  
  
• Phase 2/3 ADVANCE-1 trial of AXS-05 in AD agitation, topline data (1H 2020)

About AXS-05

AXS-05 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 consists of a proprietary formulation and doses of dextromethorphan and bupropion and utilizes Axsome's metabolic inhibition technology. The dextromethorphan component of AXS-05 is a non-competitive 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 available therapies for depression. 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 30 issued U.S. and international patents which provide protection out to 2034. AXS-05 is not approved by the FDA.

About AXS-07

AXS-07 is a novel, oral, investigational medicine with distinct dual mechanisms of action under development for the acute treatment of migraine. AXS-07 consists of MoSEIC™ meloxicam and rizatriptan. Meloxicam is a new molecular entity for migraine enabled by Axsome's MoSEIC (Molecular Solubility Enhanced Inclusion Complex) technology, which results in rapid absorption of meloxicam while maintaining a long plasma half-life. Meloxicam is a COX-2 preferential non-steroidal anti-inflammatory drug and rizatriptan is a 5-HT1B/D agonist. AXS-07 is designed to provide rapid, enhanced and consistent relief of migraine, with reduced symptom recurrence. AXS-07 is not approved by the FDA.

About AXS-12

AXS-12 (reboxetine) is a novel, oral, investigational medicine in development for the treatment of the symptoms of narcolepsy. AXS-12 is a highly selective and potent norepinephrine reuptake inhibitor. AXS-12 is an investigational drug product not approved by the FDA.
