SHENZHEN, CHINA – China Medical System Holdings Limited (“CMS”, or the “Group”) is pleased to announce that on 13 March 2026, new drug for renal anaemia Desidustat Tablets (the “Product”) has been approved for marketing in China by the National Medical Products Administration of the People’s Republic of China (NMPA). The Product is a novel, oral HypoxiaInducible Factor-Prolyl Hydroxylase Inhibitor (HIF-PHI) for treating anaemia in non-dialysis adult, Chronic Kidney Disease (CKD) patients.

The approval of Desidustat Tablets will further strengthen the Group’s overall layout in the field of nephrology, and synergize with the marketed innovative drug Velphoro (Sucroferric Oxyhydroxide Chewable Tablets, indicated for CKD hyperphosphatemia). Through the efficient linkage of nephrology expert resources and channel networks, the Group is expected to rapidly promote the large-scale clinical application of Desidustat Tablets, providing differentiated treatment options for Chinese CKD patients with renal anaemia and making a positive contribution to the Group’s performance.

As a novel oral HIF-PHI, the Product’s mechanism of action promotes erythropoiesis through increasing endogenous erythropoietin, improving iron availability and reducing hepcidin. Its China Phase III clinical trial has demonstrated positive results. The primary endpoint of the haemoglobin (Hb) mean change from baseline to Week 7-9 has indicated that, Desidustat is more effective than placebo in increasing Hb level. Results from the extension study demonstrate that the Product can maintain Hb level within the target range over the long term with acceptable safety. In addition, the Product significantly reduces hepcidin levels and ameliorates iron metabolism disorders.

There is still a large unmet need in the treatment of anaemia in CKD patients in China. It is estimated that there are more than 120 million CKD patients in China^[1]. Anaemia is one of the frequent complications of CKD, which exhibits a progressively increasing incidence with disease progression. A survey in China showed that the prevalences of anaemia in patients at CKD stage 1 to 5 were 22.0%, 37.0%, 45.4%, 85.1%, and 98.2%, respectively^[2]. The target-achieving rate (the Hb level reaching the target value (110~120g / L)) has increased to 51.5% for haemodialysis CKD patients with anaemia^[3], but is still only 8.2% for anaemia patients in non-dialysis CKD^[4]. The Product is administrated orally, thus expecting to improve the treatment compliance of patients and to meet the unmet treatment needs in the field of CKD anaemia.

Desidustat Tablets have been approved for marketing in India.
