SHENZHEN, CHINA – January 08, 2025 – (ACN Newswire) – China Medical System Holdings Limited (the “Company”, together with its subsidiaries, the “Group” or “CMS”) is pleased to announce that on 8 January 2025, the Group through a wholly-owned subsidiary of the Company entered into a License, Collaboration and Distribution Agreement  (the “Agreement”)  with Alpha Cognition Inc. (“Alpha”) of the improved new drug ZUNVEYL（benzgalantamine delayed-release tablets）(“ZUNVEY” or  the “Product”)  for the treatment of mild-to-moderate dementia of the Alzheimer’s type. The Group is entitled to an exclusive right to develop, register, manufacture, import, export and commercialize the Product in Asia (excluding Japan), Australia and New Zealand (the “Territory”), Alpha reserves the right to manufacture and supply in the Territory. The term of cooperation commences on the effective date of the Agreement and extends for twenty years, which may be automatically renewed every five years upon the expiration unless terminated by notice from either party. As the second oral therapy approved by the U.S. Food and Drug Administration (FDA) for the treatment of Alzheimer’s disease during the past decade, ZUNVEYL demonstrates a potentially better safety profile to improve compliance of patients and therefore brings clinical benefits. CMS has rooted in the central nervous system therapeutic fields for years, continuously deploying and developing global differentiated and innovative products to strengthen its competitiveness in its advantageous specialty therapeutic fields. ZUNVEYL will further diversify our Group’s innovative drug product matrix and synergize with various central nervous system products including the marketed innovative drug VALTOCO (diazepam nasal spray), the original branded drug Deanxit (flupentixol and melitracen tablets) and the innovative pipeline drug Y-3 injection (a novel brain cytoprotectant that treats stroke). Leveraging its proven clinical development capability and compliant commercialization system with high efficiency, CMS will promote the approval of ZUNVEYL in China as soon as possible to bring a new drug option for the treatment of cognitive impairment in Alzheimer’s disease patients. About ZUNVEYL ZUNVEYL was approved in July 2024 by the U.S. FDA. As a new generation of acetylcholinesterase inhibitor (AChEI), ZUNVEYL can inhibit the acetylcholinesterase from breaking down the neurotransmitter acetylcholine, increase the level of acetylcholine in the central nervous system, and therefore alleviate cognition and memory impairment in Alzheimer’s disease patients. As a prodrug of galantamine, ZUNVEYL remains inert as it passes through the stomach and the intestine, and eventually releases the active drug into the bloodstream after being metabolized by the liver. With such a mechanism of action, ZUNVEYL is expected to have equivalent efficacy as galantamine with the potential of reducing gastrointestinal (GI) side effects and addressing certain tolerability issues. Galantamine has accumulated extensive evidence of efficacy and demonstrated long-term clinical benefit in the treatment of mild-to-moderate dementia of the Alzheimer’s type since the approval of FDA in 2001[1]. Moreover, GI adverse events documented across all studies for ZUNVEYL were less than 2% and no insomnia was observed[2]. Patent in regard to use of ZUNVEYL has already been granted in China. About Alzheimer’s disease Alzheimer’s disease is a chronic, progressive neurodegenerative disease characterized by progressive decline in memory and other cognitive functions, among which some of the patients will progress to dementia. Dementia is a kind of syndrome with acquired cognitive function impairment as the core symptom, and can lead to the reduction of patients’ daily living, learning, working and social interaction ability. Alzheimer dementia accounts for 50% to 70% of all types of dementia[3,4]. According to the epidemiological study results published in the Lancet Public Health[5], there are about 9.83 million patients with Alzheimer dementia in China, of which 7.93 million are mild-to-moderate[6]. With the intensifying aging trend, the number of patients and the consequent disease burden will further increase in the future. Currently the clinical treatment of Alzheimer’s disease can be categorized as improving cognitive symptoms and decelerating disease progression[7], and AChEI belongs to the former. According to the Research Report on the Diagnosis and Treatment of Alzheimer’s disease Patients in China[8], the high incidence of side effects is one of the major pain points for existing drugs for Alzheimer’s disease, suggesting that Alzheimer’s disease patients still have an urgent need for safer therapies. About ALPHA Alpha is a commercial stage, biopharmaceutical company dedicated to developing treatments for patients suffering from neurodegenerative diseases, such as Alzheimer’s disease and cognitive impairment with mild Traumatic Brain Injury. On July 2024, Alpha received approval by the FDA of its New Drug Application (NDA) for ZUNVEYL for the treatment of mild-to-moderate Alzheimer’s disease. Alpha will now focus on the development of commercial manufacturing and commercial sales of ZUNVEYL oral tablet formulation. Additionally, Alpha has three pre-clinical development programs: ZUNVEYL in combination with memantine for the treatment of moderate-to-severe Alzheimer’s disease, ALPHA-1062 sublingual formulation for the treatment of mild-to-moderate Alzheimer’s disease, ALPHA-1062 intranasal formulation for the treatment of cognitive impairment with mild Traumatic Brain Injury.
