Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that the European Medicines Agency (EMA) has granted orphan medicinal product designation to reldesemtiv for the treatment of amyotrophic lateral sclerosis (ALS). Previously reldesemtiv was granted orphan drug designation for the treatment of ALS by the U.S. Food & Drug Administration.
SOUTH SAN FRANCISCO, Calif., March 04, 2020 (GLOBE NEWSWIRE) -- Cytokinetics, Inc. (Nasdaq: CYTK) today announced that the European Medicines Agency (EMA) has granted orphan medicinal product designation to reldesemtiv for the treatment of amyotrophic lateral sclerosis (ALS). Previously reldesemtiv was granted orphan drug designation for the treatment of ALS by the U.S. Food & Drug Administration. Cytokinetics is developing reldesemtiv, a fast skeletal muscle troponin activator (FSTA), as a potential treatment for people with ALS, SMA and certain other debilitating diseases and conditions associated with skeletal muscle weakness and/or fatigue.
Orphan medicinal product designation is adopted by the European Commission based on an opinion by the EMA’s Committee for Orphan Medicinal Products (COMP). Orphan medicinal product designation is granted by the EMA to medicines intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating disease affecting fewer than 5 in 10,000 persons in the European Union, or for which it is unlikely that the costs associated with the development and commercialization of the medicine would be recovered by expected sales under normal market conditions without the incentives provided by the designation. The designation offers potential incentives, which may include a ten-year period of EU marketing exclusivity from the date of marketing authorization, EU-funded research, protocol assistance and fee reductions.
“Receipt of orphan status in Europe builds on the orphan status we received in the U.S., reinforcing the continued unmet need for patients in these key regions who are combatting weakening muscle function and the relentless challenges related to ALS,” said Fady I. Malik, M.D., Ph.D., Cytokinetics’ Executive Vice President of Research & Development.
About Reldesemtiv
Skeletal muscle contractility is driven by the sarcomere, the fundamental unit of skeletal muscle contraction and a highly ordered cytoskeletal structure composed of several key proteins. Skeletal muscle myosin is the motor protein that converts chemical energy into mechanical force through its interaction with actin. A set of regulatory proteins, which includes tropomyosin and several types of troponin, make the actin-myosin interaction dependent on changes in intracellular calcium levels. Reldesemtiv, a next-generation FSTA arising from Cytokinetics’ skeletal muscle contractility program, slows the rate of calcium release from the regulatory troponin complex of fast skeletal muscle fibers, which sensitizes the sarcomere to calcium, leading to an increase in skeletal muscle contractility. Reldesemtiv has demonstrated pharmacological activity that may lead to new therapeutic options for diseases associated with skeletal muscle weakness and fatigue.
FORTITUDE-ALS, the Phase 2 clinical trial of reldesemtiv in patients with ALS, showed that the trial did not achieve statistical significance for a pre-specified dose-response relationship in the primary endpoint of change from baseline in slow vital capacity (SVC) after 12 weeks of dosing (p=0.11). However, patients on all dose groups of reldesemtiv declined numerically less than patients on placebo for SVC and ALS Functional Rating Scale-Revised (ALSFRS-R), with larger differences emerging over time.
About ALS
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that afflicts approximately 20,000 people in the United States and a comparable number of patients in Europe. Approximately 5,000 new cases of ALS are diagnosed each year in the United States. The average life expectancy of an ALS patient is approximately three to five years after diagnosis and only approximately 10 percent of patients survive for more than 10 years. Death is usually due to respiratory failure because of diminished strength in the skeletal muscles responsible for breathing. Few treatment options exist for these patients, resulting in a high unmet need for new therapies to address functional deficits and disease progression.
About Cytokinetics and Astellas Collaboration
In 2013, Cytokinetics and Astellas formed a partnership focused on the research, development, and potential commercialization of skeletal muscle activators. The primary objective of the collaboration is to advance novel therapies for diseases and medical conditions associated with muscle impairment and weakness. Cytokinetics initially exclusively licensed to Astellas rights to co-develop and potentially co-commercialize reldesemtiv and other FSTAs in non-neuromuscular indications and to develop and commercialize other novel mechanism, skeletal muscle activators in all indications. Under the agreement as subsequently expanded and amended, Astellas also has exclusive rights to co-develop and commercialize reldesemtiv and other FSTAs in certain neuromuscular indications (including SMA and ALS). Cytokinetics has certain development and commercialization rights, including the right to co-promote FSTAs for neuromuscular indications in the U.S., Canada and Europe and to co-promote the other collaboration products in the U.S. and Canada. In November 2019, Cytokinetics and Astellas agreed in principle to revise the terms of the collaboration with respect to reldesemtiv whereby Cytokinetics would obtain exclusive control of the product and Astellas, for reduced collaboration funding and the provision of certain support, would obtain low- to mid-single future royalties on reldesemtiv in certain markets. Until the companies finalize revisions, the collaboration remains in effect in accordance with its current terms, the agreement in principle remains non-binding, and there can be no assurance Cytokinetics will enter into definitive agreements with Astellas regarding any revised terms.
About Cytokinetics
Cytokinetics is a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle activators and next-in-class muscle inhibitors as potential treatments for debilitating diseases in which muscle performance is compromised and/or declining. As a leader in muscle biology and the mechanics of muscle performance, the company is developing small molecule drug candidates specifically engineered to impact muscle function and contractility. Cytokinetics is collaborating with Amgen Inc. (Amgen) to develop omecamtivmecarbil, a novel cardiac muscle activator. Omecamtivmecarbil is the subject of an international clinical trials program in patients with heart failure including GALACTIC-HF and METEORIC-HF. Amgen holds an exclusive worldwide license to develop and commercialize omecamtivmecarbil with a sublicense held by Servier for commercialization in Europe and certain other countries. Cytokinetics is collaborating with Astellas Pharma Inc. (Astellas) to develop reldesemtiv, a fast skeletal muscle troponin activator (FSTA). Astellas currently holds an exclusive worldwide license to develop and commercialize reldesemtiv. Licenses held by Amgen and Astellas are subject to specified co-development and co-commercialization rights of Cytokinetics. Cytokinetics is also developing CK-274, a novel cardiac myosin inhibitor that company scientists discovered independent of its collaborations, for the potential treatment of hypertrophic cardiomyopathies (HCM). Cytokinetics is conducting REDWOOD-HCM, a Phase 2 trial of CK-274 in patients with obstructive HCM. Cytokinetics continues its over 20-year history of pioneering innovation in muscle biology and related pharmacology focused to diseases of muscle dysfunction and conditions of muscle weakness.
