Topline results now anticipated in 2H 2019
Trial enriched with only patients with history of inadequate response to prior migraine treatments
Trial compares AXS-07 to placebo and active comparator
Trial being conducted under FDA Special Protocol Assessment (SPA)
Company to discuss development on the conference call scheduled today at 8:00 AM Eastern
NEW YORK, May 06, 2019 (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 the acceleration of the timeline for reporting topline results from the MOMENTUM Phase 3 trial of AXS-07 (MoSEIC™ meloxicam and rizatriptan), Axsome’s novel, oral, investigational medicine with distinct dual mechanisms of action for the acute treatment of migraine. The trial is being conducted pursuant to a U.S. Food and Drug Administration (FDA) Special Protocol Assessment (SPA). The first patient was enrolled in the MOMENTUM trial in March 2019, and currently approximately 40% of the target number of patients have been randomized. Based on the faster-than-expected enrollment in this trial, topline results are now expected in the second half of 2019, versus previous guidance of the first quarter of 2020.
The MOMENTUM (Maximizing Outcomes in Treating Acute Migraine) Phase 3 trial is a randomized, double-blind, placebo- and active-controlled study of AXS-07 for the acute treatment of migraine, in which patients are randomized to treatment with AXS-07, rizatriptan, meloxicam, or placebo. Rizatriptan, the active comparator in the trial, is considered to be one of the most efficacious oral medications currently available for the acute treatment of migraine [1].
Patients enrolled in the MOMENTUM trial must have a history of inadequate response to prior acute migraine treatments, assessed using the Migraine Treatment Optimization Questionnaire (mTOQ-4). The mTOQ-4 is a validated questionnaire that assesses efficacy response to prior acute treatments based on four aspects (two-hour pain freedom, efficacy for at least 24 hours with one dose, ability to plan daily activities, and disruption of daily activities) [2]. In addition to having a history of inadequate response, the majority of patients randomized to date in the MOMENTUM trial also report allodynia with their migraine attacks. Allodynia, which is pain from normally non-painful stimuli (such as brushing hair, wearing glasses, taking a shower, etc.), has been shown to be strongly associated with worse outcomes for pain freedom and pain relief after treatment with triptan medications [3,4].
The MOMENTUM trial is being enriched with difficult-to-treat patients because they represent a population for whom superior medicines are urgently needed. The rapid absorption and distinct dual mechanisms of action of AXS-07 provide a scientific rationale for potential success in providing relief for this more treatment resistant population. AXS-07 consists of MoSEIC™ meloxicam and rizatriptan. Meloxicam, a COX-2 preferential non-steroidal anti-inflammatory drug, 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. Rizatriptan is a potent 5-HT1B/D agonist.
“The stringent design of the MOMENTUM trial, which is enrolling a difficult-to-treat patient population and utilizing a potent active comparator, sets a high bar for the demonstration of efficacy of AXS-07,” said Herriot Tabuteau, MD, Chief Executive Officer of Axsome. “Success in this trial would highlight the potentially differentiated efficacy profile of this novel, oral treatment with distinct dual mechanisms of action, designed to address the unmet medical needs in the acute treatment of migraine. We are pleased with the pace of enrollment and look forward to the results of the MOMENTUM trial, anticipated in the second half of 2019, which, if positive, would support the filing of an NDA for AXS-07 potentially as early as 2020.”
Elements of the MOMENTUM Trial:
- Eligible patients are randomized in a 2:2:2:1 ratio to treatment with AXS-07, rizatriptan, meloxicam, or placebo. The target number of patients is approximately 875.
- Eligible patients must have a history of inadequate response to prior acute migraine treatments, assessed using the mTOQ-4 questionnaire.
- Co-primary endpoints are freedom from headache pain two hours after dosing, and freedom from the most bothersome migraine-associated symptom (nausea, photophobia, or phonophobia) two hours after dosing, for AXS-07 as compared to placebo.
- Superiority of AXS-07 to the rizatriptan and meloxicam arms (component contribution) will be established based on sustained freedom from headache pain from two to 24 hours after dosing.
The MOMENTUM study is being conducted pursuant to an SPA with the FDA. The SPA provides agreement that the overall MOMENTUM trial design (e.g., entry criteria, dose selection, endpoints) and planned analysis adequately address objectives that, if met, will support the regulatory submission for approval of AXS-07 for the indication of acute treatment of migraine in adults with or without aura.
Conference Call Information
Axsome will host a conference call and webcast today at 8:00 AM Eastern to discuss the progress of the MOMENTUM Phase 3 trial in the acute treatment of migraine as well as AXS-05 in the treatment of major depressive disorder following a Breakthrough Therapy meeting with the FDA. To participate in the live conference call, please dial (844) 698-4029 (toll-free domestic) or (647) 253-8660 (international), and use the conference ID 3977129.

A replay of the webcast will be available for approximately 30 days following the live event.
About the MOMENTUM Trial
MOMENTUM is a Phase 3, randomized, double-blind, multicenter, controlled trial to assess the efficacy and safety of AXS-07 in the acute treatment of migraine. Approximately 875 patients, with a history of inadequate response to prior migraine treatments, will be randomized in a 2:2:2:1 ratio to treatment with AXS-07, rizatriptan, meloxicam, or placebo. The two co-primary endpoints of the trial are the proportion of patients who are free from headache pain two hours after dosing, and the proportion of patients who no longer suffer from their most bothersome migraine-associated symptom (nausea, photophobia, or phonophobia) two hours after dosing, for AXS-07 as compared to placebo.
About Migraine
Over 37 million Americans suffer from migraine according to the Centers for Disease Control, and it is the leading cause of disability among neurological disorders in the United States according to the American Migraine Foundation. Migraine is characterized by recurrent attacks of pulsating, often severe and disabling head pain associated with nausea, and sensitivity to light and or sound. It is estimated that migraine accounts for $78 billion in direct (e.g. doctor visits, medications) and indirect (e.g. missed work, lost productivity) costs each year in the United States [5]. Published surveys of migraine sufferers indicate that more than 70% are not fully satisfied with their current treatment, that nearly 80% would try a new therapy, and that they desire treatments that work faster, more consistently, and result in less symptom recurrence [6,7].
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.
