"We believe that AXS-02 holds promise in the treatment of knee OA due to its unique, non-opioid mechanisms of action for pain," said Randall Kaye, M.D., Chief Medical Officer of Axsome. "AXS-02 potently inhibits bone turnover and localizes preferentially to regions of increased turnover. BMLs therefore represent an entirely novel biomarker strategy for identifying knee OA patients that may respond to AXS-02 treatment.""We are pleased to initiate a Phase 3 trial in this important indication which touches the lives of so many," said Herriot Tabuteau, M.D., Chief Executive Officer of Axsome. "The initiation of the COAST-1 study represents the achievement of another key milestone for Axsome, following our initial public offering in November 2015. Axsome has now initiated three pivotal trials, in three indications, with two product candidates, in less than one year." About the COAST-1 Study COAST-1 (Clinical Knee Osteoarthritis Symptom Treatment 1) is a randomized, double-blind, placebo-controlled trial to assess the efficacy and safety of AXS-02 administered orally to patients with knee osteoarthritis (OA) associated with bone marrow lesions (BMLs). This trial is anticipated to enroll approximately 346 patients with clinically diagnosed knee OA and at least one confirmed BML in the affected knee on MRI. Eligible patients must be at least 50 years of age, either male or postmenopausal female, and have at least moderate pain intensity. After a baseline period, patients meeting the entry criteria will be randomized in a 1:1 ratio to receive either (1) AXS-02 tablets once per week or (2) matching placebo tablets once per week, under fasting conditions for 6 weeks. Randomized patients will remain blinded for an additional 18 weeks, totaling 24 weeks for the double-blind phase. The primary endpoint is the change in pain intensity from baseline to week 24, measured using a 0-10 numerical rating scale (NRS). Axsome has reached agreement with the U.S. Food and Drug Administration (FDA) regarding a Special Protocol Assessment (SPA) for the COAST-1 study. The SPA provides agreement that the design and planned analysis of the COAST-1 study adequately address objectives that, if met, would support a regulatory submission for approval of AXS-02 for the treatment of the pain of knee OA associated with BMLs.
About AXS-02AXS-02 (disodium zoledronate tetrahydrate) is a potent osteoclast inhibitor being developed as an oral, targeted, non-opioid, potentially first-in-class therapeutic for chronic pain. AXS-02 has a high affinity for bone mineral, and reduces osteoclast activity by inhibiting the farnesyl pyrophosphate synthase (FPPS) enzyme. AXS-02 is being developed for the treatment of complex regional pain syndrome (CRPS), the pain of knee osteoarthritis (OA) associated with bone marrow lesions (BMLs), and chronic low back pain (CLBP). Phase 3 trials are underway with AXS-02 in CRPS and knee OA associated with BMLs, and are planned in CLBP. AXS-02 is an investigational medication not approved by the FDA. About Knee Osteoarthritis (OA) associated with Bone Marrow Lesions (BMLs) Knee OA is a disorder characterized by periarticular bone changes, progressive loss of articular cartilage, joint space narrowing, and eventual total joint failure. It is clinically manifested by knee pain, significant physical disability, and reduced quality of life. BMLs are regions of increased signal intensity on magnetic resonance imaging (MRI) of the knee in patients with knee OA. BMLs are strongly associated with the presence and severity of knee pain, and predict disease severity and structural progression in patients with knee OA, based on published studies. Results of epidemiological studies suggest that there are approximately 7 million symptomatic patients in the United States, 50 years of age and older, with radiographic knee OA and BMLs. About Axsome Therapeutics, Inc. Axsome Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, including pain, for which there are limited existing treatment options. Axsome's product candidate portfolio includes two late-stage candidates, AXS-02 and AXS-05. AXS-02 is currently in Phase 3 trials in complex regional pain syndrome (CRPS) and knee osteoarthritis (OA) associated with bone marrow lesions (BMLs) with an additional Phase 3 trial planned in chronic low back pain (CLBP) associated with Modic changes (MCs). AXS-05 is currently in a Phase 3 trial in treatment resistant depression (TRD). AXS-02 and AXS-05 are investigational products not approved by the FDA.
