SHENZHEN, CHINA – China Medical System Holdings Limited (the “Company”, together with its subsidiaries, the “Group” or “CMS”) is pleased to announce that on 2 December 2024, the Group through a wholly-owned subsidiary of the Company entered into an Exclusive Commercialization Agreement (the “Agreement”) with Atom Therapeutics Co., Ltd (hereinafter referred to as “Atom Therapeutics”, formerly named as “Jiangsu Atom Bioscience and Pharmaceutical Co., Ltd.”) of class 1 innovative drug ABP-671 for the treatment of gout and hyperuricemia (the “Product”). In accordance with the Agreement, the Group is entitled to an exclusive commercialization right of the Product in Mainland China, Hong Kong Special Administrative Region and Macao Special Administrative Region. The term of cooperation commences on the effective date of the Agreement and extends for ten years from the date the Product is first approved for market launch in Mainland China (the “Authorization Term”). Upon the expiration of the Authorization Term, it may be automatically renewed for an additional ten years, subject to specific conditions stipulated in the Agreement.
ABP-671 is a class 1 innovative chemotherapeutic drug for the treatment of gout and hyperuricemia, currently in Phase 2b/3 clinical trials for gout in China and overseas. The Product reduces renal re-absorption of uric acid by inhibiting Urate Anion Transporter 1 (URAT1). The results of two completed phase 2 clinical trials demonstrated favorable efficacy and safety profiles across multiple dose groups (ranging from 1 mg to 12 mg) of ABP-671. The 2 mg once-daily dosage of the Product was proved to be as effective as, or even better than, benzbromarone or febuxostat (maximum dosage of 80mg). The reduction in uric acid levels was sustained throughout the 24-hour period, with no significant safety concerns identified. This product is anticipated to offer more effective and safer treatment alternatives for patients suffering from gout and hyperuricemia[1]. Multiple patents in regard to substance and use of the ABP-671 have been granted in China.
Hyperuricemia is defined as a fasting blood uric acid level exceeding 420μmol/L (7.0 mg/dL) in adults on a normal purine diet on two separate days. The deposition of urate crystals in hyperuricemia patient results in arthritis, medically termed gout. Hyperuricemia and gout can cause acute and chronic inflammatory injury in articular cartilage, bone, kidney and vascular wall, which can lead to multiple organ damage of the heart, brain and kidney, etc. The data presented in the White Paper on Hyperuric Acid and Gout Trends in China (2021) indicates that, the incidence rate of hyperuricemia is 13.3%, with approximately 177 million hyperuricemia patients and the incidence rate of gout is 1.1% in general, with about 14.66 million gout patients in China. Frost & Sullivan indicates that, the number of people with hyperuricemia and gout in China will continue to increase in the future, reaching 240 million and 52.2 million respectively by 2030. Currently, the commonly used uric acid-lowering drugs in clinical practice in China are those which inhibit uric acid synthesis or promote uric acid excretion. Due to certain limitations in the efficacy and safety of the marketed uric acid-lowering drugs, such as causing renal failure, sudden cardiac death or severe liver toxicity. There is still an urgent need for effective and safe uric acid-lowering drugs among gout and hyperuricemia patients in China.
ABP-671 is currently with the potential to be the promising and safe product for the treatment of gout and hyperuricemia. Through this collaboration, it fills the blank in the CMS’s product portfolio of the treatment of gout. Gout and hyperuricemia are both rheumatic diseases and chronic metabolic diseases, which are highly consistent with the Group’s strategic layout in the cardio-cerebrovascular/ gastroenterology business and the network resources of marketed products. If approved for marketing in the future, the Product will synergize with the Group’s marketed product Metoject (methotrexate injection) in rheumatology and with Elcitonin (elcatonin injection) in endocrinology and orthopedics, in terms of expert network and market resources. Based on the unmet clinical needs and the expected solid clinical data of the Product, the Group is looking forward to the smooth advancement of the clinical development of ABP-671, allowing patients with relevant indications to benefit from this innovative treatment sooner.
