NEW YORK, Jan. 13, 2020 (GLOBE NEWSWIRE) -- Axsome Therapeutics, Inc. (NASDAQ: AXSM), a clinical-stage biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, has entered into an agreement with Pfizer Inc. (NYSE: PFE) for an exclusive U.S. license to Pfizer's clinical and nonclinical data, and intellectual property for reboxetine, the active pharmaceutical ingredient in AXS-12 which Axsome is developing for the treatment of narcolepsy. The agreement also provides Axsome exclusive rights to develop and commercialize esreboxetine, a new late-stage product candidate now referred to as AXS-14, in the U.S. for the treatment of fibromyalgia.
Under the terms of the agreement, Axsome will receive from Pfizer an exclusive U.S. license to Pfizer data for reboxetine and esreboxetine encompassing a full range of nonclinical studies, and short-term and long-term clinical trials involving more than five thousand patients. The licensed data includes results of a positive Phase 3 and a positive Phase 2 trial of esreboxetine in the treatment of fibromyalgia. Axsome will have the exclusive right and sole responsibility of developing AXS-14 (esreboxetine) in the U.S. for the treatment of fibromyalgia and for other indications.
Pfizer will receive shares of Axsome common stock having a value of $8 million, based on the average closing price of Axsome's common stock for the 10 prior trading days, in consideration for the license and rights. Pfizer will also receive an upfront cash payment of $3 million, up to $323 million in regulatory and sales milestones, and tiered mid-single to low double-digit royalties on future sales. Pfizer will also have a right of first negotiation on any potential future strategic transactions involving AXS-12 and AXS-14.
Axsome recently completed and announced positive results for a Phase 2 trial of AXS-12 in the treatment of narcolepsy and is preparing to advance AXS-12 into Phase 3 trials for the treatment of narcolepsy in 2020, as previously disclosed.
"We are very pleased to announce this agreement with Pfizer to help advance the development of AXS-12 for the treatment of narcolepsy and of AXS-14 for the treatment of fibromyalgia, two serious CNS disorders which currently have limited treatment options," said Herriot Tabuteau, MD, Chief Executive Officer of Axsome. "The valuable clinical and nonclinical data under this exclusive license will enable us to potentially significantly accelerate our AXS-12 clinical program while reducing development risk and costs. Furthermore, through this agreement, we are able to expand our CNS pipeline with AXS-14, which has demonstrated efficacy in completed Phase 3 and Phase 2 trials in fibromyalgia. With the recently announced Phase 2 success of AXS-12 resulting in its planned advancement to Phase 3 this year, and with the addition of AXS-14, our pipeline will now contain four differentiated Phase 3-stage product candidates with the potential to positively affect many of the millions of people living with distressing CNS disorders."
Summary of the Agreement
Reboxetine (AXS-12)
- Axsome will receive from Pfizer an exclusive U.S. license to data from a full range of nonclinical studies with reboxetine, to data from numerous short-term and long-term clinical trials of patients treated with reboxetine, and to other reboxetine intellectual property. Reboxetine is not approved in the U.S. for any indication and is marketed by Pfizer outside of the U.S. for the treatment of depression.
- Reboxetine is the active pharmaceutical ingredient in AXS-12 which is being developed for the treatment of narcolepsy. Axsome recently completed and announced positive results for a Phase 2 trial of AXS-12 in the treatment of narcolepsy, demonstrating statistically significant improvements in cataplexy, excessive daytime sleepiness, as well as cognitive function compared to placebo. Axsome is preparing to initiate Phase 3 trials of AXS-12 in the treatment of narcolepsy in 2020, as previously disclosed.
- The licensed nonclinical and clinical data are expected to reduce or eliminate the need for Axsome to conduct certain studies thereby mitigating risk and associated costs, and potentially significantly accelerating the clinical development and commercialization timelines of AXS-12.
- Axsome has Orphan Drug Designation for AXS-12 in the treatment of narcolepsy, and 2 pending U.S. patents covering AXS-12.
Esreboxetine (AXS-14)
- Axsome will receive from Pfizer an exclusive license to develop and commercialize esreboxetine, now referred to as AXS-14, in the U.S. for fibromyalgia and all other indications. The license encompasses nonclinical and clinical data for esreboxetine including results from a positive Phase 3 and a positive Phase 2 trial of esreboxetine in the treatment of fibromyalgia conducted by Pfizer.
- Esreboxetine, the SS-enantiomer of racemic reboxetine, is the more selective and potent enantiomer, which has been evaluated for the treatment of fibromyalgia. Fibromyalgia is a chronic disorder characterized by widespread pain, fatigue, disturbed sleep, depression, and cognitive impairment. The condition affects approximately 5 million Americans of whom approximately 90% are women. It is considered to be mediated mainly in the CNS. Treatment options for fibromyalgia are limited with only three pharmacologic treatments currently approved by the FDA.
- In a Phase 3 trial conducted by Pfizer in 1,122 patients with fibromyalgia treated with esreboxetine or placebo for 14 weeks, the study met the two primary endpoints demonstrating statistically significant improvements compared to placebo in the weekly mean pain score (p<0.001, p<0.001, and p=0.025, for 4 mg, 8 mg and 10 mg daily doses, respectively), and the Fibromyalgia Impact Questionnaire (FIQ) total score (p<0.001, p<0.001, and p=0.023, for 4 mg, 8 mg and 10 mg doses, respectively). Esreboxetine also resulted in statistically significant improvements as compared to placebo on the Patient's Global Impression of Change (PGI-C) scale (p=0.002, p=0.001, and p=0.007, for 4 mg, 8 mg and 10 mg doses, respectively), and in fatigue as measured using the Global Fatigue Index (p=0.001 and p=0.001, for 4 mg and 8 mg daily doses, respectively).1
- In a Phase 2 trial conducted by Pfizer in 267 patients with fibromyalgia treated with esreboxetine (dose escalated to 8 mg/day) or placebo for 8 weeks, the study met its primary endpoint demonstrating statistically significant improvements compared to placebo in the weekly mean pain score (p=0.006). The study also demonstrated statistically significant improvements in additional efficacy outcomes including the FIQ total score (p<0.001), the PGIC scale (p<0.001), and fatigue as measured using the Multidimensional Assessment of Fatigue scale (p<0.001).2
- AXS-14 expands Axsome's late-stage pipeline of product candidates for difficult-to-treat CNS disorders.
- Axsome has 3 pending U.S. patents covering AXS-14.
Financial Terms
- Pfizer will receive shares of Axsome common stock having a value of $8 million, based on the average closing price of Axsome's common stock for the 10 prior trading days. Pfizer will also receive an upfront cash payment of $3 million.
- Pfizer will receive up to $323 million in regulatory and sales milestones, and tiered mid-single to low double-digit royalties on future sales.
- Pfizer will have a right of first negotiation on any potential future strategic transactions involving AXS-12 or AXS-14.

About Narcolepsy
Narcolepsy can be a serious and debilitating neurological condition that causes dysregulation of the sleep-wake cycle and is characterized clinically by excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, sleep paralysis, and disrupted nocturnal sleep. Narcolepsy afflicts an estimated 185,000 individuals in the U.S. Cataplexy is seen in an estimated 70% of narcolepsy patients and is a sudden reduction or loss of muscle tone while a patient is awake, typically triggered by strong emotions such as laughter, fear, anger, stress, or excitement. Narcolepsy interferes with cognitive, psychological, and social functioning, increases the risk of work- and driving-related accidents, and is associated with a 1.5 fold higher mortality rate. Depression is reported in up to 57% of patients.
About Fibromyalgia
Fibromyalgia is a chronic disorder often characterized by widespread pain, fatigue, disturbed sleep, depression, and cognitive impairment. Other symptoms of this disorder can include tingling in the hands and feet and headaches. Fibromyalgia is considered to be mediated mainly in the central nervous system. Approximately 5 million Americans, 90% of whom are women, are estimated to suffer from fibromyalgia. Treatment options for fibromyalgia are limited with only three pharmacologic treatments currently approved by the FDA.
About AXS-12
AXS-12 (reboxetine) is a highly selective and potent norepinephrine reuptake inhibitor for the treatment of narcolepsy.
