Phase 2a Study to Evaluate PRS-080 in Anemic Chronic Kidney Disease Patients

This is a multi-center, randomized, double-blind, placebo-controlled, multiple ascending dose, pilot Phase 2a study in anemic stage 5 chronic kidney disease patients requiring hemodialysis. Eligible patients will undergo screening assessments and PRS-080#22-DP will be administered by intravenous infusion. The study will consist of 2 dose cohorts of 4 mg/kg and 8 mg/kg body weight with 6 patients in each cohort. Using a standard 4+2 design, 4 patients in each cohort will be randomized to PRS-080#022-DP and 2 patients in each cohort will be randomized to placebo. The decision to escalate the dose will be based on an interim analysis of clinical and laboratory safety as well on a comparison with pharmacokinetic data. Safety and tolerability, pharmacokinetics, pharmacodynamics as well as potential immunogenicity will be investigated.
