Analyst · Ladenburg Thalmann. Matt, your line is open
Thank you, Mark. Good morning, everyone and thank you all for joining Axsome Therapeutics fourth quarter and full year 2018 results conference call. Axsome is committed to developing novel medicines for patients with serious CNS disorders, a population that is underserved by the limited treatment options for many of these disorders. We took significant steps toward this goal in 2018 and have continued that momentum so far this year. As a result of efforts by our team, we now have three differentiated CNS product candidates, AXS-05, AXS-07, and AXS-12 in active clinical development across six different indications. Cedric will speak in detail about all of our ongoing clinical trials with these candidates shortly. But first, I wanted to share some of my thoughts on our accomplishments in 2018 and the opening months of 2019. Since this time last year, we have advanced our ongoing clinical trials with AXS-05, our novel, oral NMDA receptor antagonist with multimodal activity. We have unveiled new internally generated product candidates and launched clinical trials in new indications. In 2018, we announced positive outcomes of the interim analysis of STRIDE-1 Phase 3 trials of AXS-05 in treatment resistant depression and the ADVANCE-1 Phase 2/3 trial of AXS-05 in agitation associated with Alzheimer’s disease. Additionally, in little more than 6 months, we initiated, executed and completed a positive ASCEND Phase 2 trial of AXS-05 in major depressive disorder, or MDD. This study allowed us to demonstrate for the first time the rapid substantial and statistically significant antidepressant effect for AXS-05 as compared to an active comparator. Based on these results we now intend to develop AXS-05 for the indication of MDD in addition to treatment resistant depression and plan to meet with the FDA in the second quarter to discuss the potential of regulatory path for the broader MDD indication. In 2018, we also continued development of our AXS-07 product candidate for the acute treatment of migraine. In addition to AXS-05 and AXS-07, we expanded our CNS product portfolio with the addition of another internally generated product candidate AXS-12 for narcolepsy. We subsequently received FDA orphan drug designation for AXS-12 for the treatment of this disabling disorder. As we focused on growing our core CNS portfolio, we created a separate business unit called Axsome Pain and Primary Care or Axsome PPC to house and enhance the value of our non-core pain and primary care assets. Two of the product candidates AXS-06 and AXS-02 which were housed in Axsome PPC are being developed directly by Axsome. And one of the product candidates, neridronate is covered by Axsome’s intellectual property portfolio. In addition to the significant expansion of our clinical development portfolio, we have also considerably strengthened our financial position. Axsome’s recent financings, which total $46 million, expand the company’s cash runaway into at least fourth quarter of 2021 based on current operating plans. This is well beyond data readouts for all of our ongoing clinical trials with AXS-05, AXS-07 and AXS-12. 2019 is already off to a busy start. In addition to reporting positive top line results from our Phase 2 ASCEND trial of AXS-05 in MDD, we have recently launched a CONCERT Phase 2 trial of AXS-12 in narcolepsy and the MOMENTUM Phase 3 trial of AXS-07 in migraine. We expect top line results from the CONCERT study of AXS-12 in narcolepsy in the second quarter of 2019. The MOMENTUM study of AXS-07 in the acute treatment of migraine is being conducted pursuant to a special protocol assessment with the FDA. Top line results from the MOMENTUM study are expected through the first quarter of 2020. I am proud of all that our team has accomplished over the past 15 months and we look forward to top line results from the Phase 3 STRIDE-1 trial of AXS-05 in treatment resistant depression, the Phase 2 trial of AXS-05 in smoking cessation, the Phase 2 CONCERT trial of AXS-12 in narcolepsy, the Phase 3 MOMENTUM trial of AXS-07 in migraine and the Phase 2/3 ADVANCE trial of AXS-05 in Alzheimer’s disease agitation over the coming quarters. For more detail regarding these ongoing clinical programs, I will turn the call over to Cedric.
Cedric O’Gorman: Thank you, Herriot. And I am pleased to review our five ongoing CNS clinical programs and provide an update on the status and timelines of these studies. Let us first consider our clinical programs with AXS-05. AXS-05 is a novel oral investigational NMDA receptor antagonist with multimodal activity that is being evaluated in four separate indications; treatment resistant depression, major depressive disorder, Alzheimer’s disease agitation and smoking cessation. AXS-05 is being granted FDA fast track designations for the treatment of treatment resistant depression and Alzheimer’s disease agitation. The STRIDE-1 trial is a Phase 3 multi-center randomized double blind active controlled trial to assess the efficacy and safety of AXS-05 in the treatment of treatment resistant depression. To-date approximately 95% of the target number of subjects have been randomized into this trial and we expect top line data from the STRIDE-1 study in the second quarter of 2019. As Herriot mentioned in January of this year we announced positive results for the Phase 2 ASCEND study, a randomized double blind active controlled multi-center U.S. trial of AXS-05 in acutely depressed patients with confirmed moderate to severe MDD. In this study, AXS-05 met the pre-specified primary end point by rapidly substantially and statistically significantly reducing depressive symptoms measured using the Montgomery-Åsberg Depression Rating Scale or MADRS total score as compared to the active comparator bupropion. Additionally, statistical significance was achieved versus bupropion as early as within 2 weeks from baseline. A successfully developed AXS-05 has the potential to be the first oral NMDA receptor antagonist approved for the treatment of depression. We expect to present further details of the study results at upcoming scientific meetings, meeting with the FDA in the second quarter of 2019 to discuss the potential regulatory path for developing AXS-05 for the broader MDD indication. Axsome is enrolling the ADVANCE-1 study, a Phase 2/3 multi-center randomized, double-blind, controlled trial to evaluate the efficacy and safety of AXS-05 in patients with agitation associated with Alzheimer’s disease. In December 2018, Axsome announced positive results of an interim futility analysis for the Phase 2/3 ADVANCE-1 trial. The interim analysis was conducted by an independent data monitoring committee, which recommended continuation of the AXS-05 treatment arm and no further randomization of subjects to the bupropion treatment arm. Axsome has followed the IDMC’s recommendation. The previously planned second interim analysis will no longer be performed in order to preserve statistical power for the final analysis. Today, just over 40% of the target number of subjects, have been randomized in this trial. Top line results are anticipated in the first half of 2020. AXS-05 is also being evaluated in a Phase 2 randomized double-blind controlled trial for smoking cessation treatment in smokers attempting to quit. The trial is being conducted under research collaboration between Duke University and Axsome. The primary outcome measure is the change in smoking intensity. Today, it’s approximately 95% of the target number of subjects have been randomized in this trial. Top line results are anticipated in the second quarter of 2019. Now, I will discuss AXS-07 and our acute migraine trial, the MOMENTUM study. AXS-07 consists of MoSEIC meloxicam and rizatriptan. Meloxicam is a new molecular entity for migraine enabled by Axsome’s MoSEIC or molecular solubility enhanced inclusion complex technology which results in rapid absorption of meloxicam while maintaining along 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. In February 2019, Axsome reached agreement with the FDA under a special protocol assessment or SPA for the design endpoints and statistical approach of the MOMENTUM study. The two co-primary endpoints of this trial are the proportion of patients who are free from headache pain 2 hours after dosing and the proportion of patients who no longer suffer from their most bothersome migraine associated symptom, nausea, photophobia, phonophobia, 2 hours after dosing. Enrollment in this study commenced this month and data is expected in the first quarter of 2020. Finally, I would like to describe our Phase 2 trial, the CONCERT study of AXS-12 which Axsome is developing for the treatment of narcolepsy. AXS-12 Reboxetine is a novel, oral highly selective and potent norepinephrine reuptake inhibitor. The CONCERT study is a Phase 2 double-blind randomized placebo-controlled crossover multi-center trial. Efficacy assessments will include the frequency of cataplexy attacks, and measures of other symptoms of narcolepsy. This trial has just commenced and top line data is expected in the second quarter of 2019. I would now like to turn the call over to Nick to provide the financial update for the full year of 2018.
