简要总结
A multicenter, Phase II, randomized, double-blind, single ascending dose (SAD) and multiple ascending dose (MAD), as well as single-arm clinical study evaluating the long-term efficacy and safety of MT1013 in hemodialysis subjects with secondary hyperparathyroidism. The SAD study consists of five cohorts at doses of 5, 10, 20, 40, and 60 mg. The MAD study consists of three cohorts at doses of 5, 10, and 20 mg. In both the SAD and MAD studies, each cohort includes 8 subjects (6 subjects receive the active investigational drug, and 2 subjects receive matching placebo), and the cohorts are conducted sequentially. In the long-term dosing cohort, all subjects will undergo regular hemodialysis three times per week, receiving the drug once after each hemodialysis session for a total duration of 52 weeks
