Renal Anemia of Chronic Kidney Disease

For patients with renal anemia treated with hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), there is a clinical need of switching to long-acting and safe medications. Pegmolesatide, a polyethylene glycol (PEG)-conjugated erythropoiesis-stimulating peptide, is a long-acting erythropoiesis-stimulating agent (ESA) with sustained activity. It was approved for marketing by the National Medical Products Administration (NMPA) in June 2023. Phase III clinical trials have demonstrated its efficacy and safety in dialysis patients with renal anemia who were previously treated with recombinant human erythropoietin (rHuEPO). However, there are currently no data regarding the efficacy and safety of switching from HIF-PHIs to pegmolesatide, and there is a lack of standard for the dose conversion. This study is a multi-center, prospective, open-label, randomized parallel-controlled clinical trial, planning to enroll 96 patients. All enrolled patients will receive 12 weeks of treatment and be followed up for 16 weeks.

This study is a prospective, multicenter, parallel-controlled, open-label clinical trial, planned to be conducted across multiple research centers in various provinces and cities in China. It will enroll 240 dialysis-dependent chronic kidney disease (DD-CKD) patients with anemia who have been receiving rHuEPO treatment for at least 4 weeks, with hemoglobin (Hb) levels of ≥70 g/L and \<110 g/L. After enrollment, participants will be randomly assigned in a 1:1:1 ratio to the experimental group, control group, and exploratory group. The study will involve a 24-week treatment and observation period, divided into three phases: a screening period (Day -28 to Day -1), a treatment period (Week 0 to Week 16), and an extension period (Week 17 to Week 24). The primary objective is to assess the impact of the three treatment regimens on the hemoglobin levels of patients with DD-CKD anemia.
