  Purpose
This study will investigate the levels of CTA018 in the body over time (pharmacokinetics, PK) in patients with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT), undergoing regular hemodialysis. This study will also investigate the safety and effects of different strengths of CTA018, on parathyroid hormone (PTH) levels.

Condition Intervention Phase
Chronic Kidney Disease Secondary Hyperparathyroidism Chronic Renal Insufficiency Chronic Renal Failure Drug: CTA018 Injection Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label, Four Week, Dose Escalating Pharmacokinetic, Pharmacodynamic, Efficacy and Safety Study of CTA018 Injection in Subjects With Stage 5 Chronic Kidney Disease With Secondary Hyperparathyroidism on Hemodialysis
