Phase 1

Recruiting

• Conditions: Chronic Kidney Diseases; Magnetic Resonance Imaging
• Interventions: Diagnostic Test: Polysaccharide superparamagnetic ferric oxide injection

• Registration Number: NCT05687864
• Lead Sponsor: Chia Tai Tianqing Pharmaceutical Group Co., Ltd.

Brief Summary

Polysaccharide super paramagnetic ferric oxide injection is an iron supplement developed for patients with iron deficiency anemia. Due to its characteristics, it has the potential to be a contrast agent. The DJTCSCYHT-I-04 study is a single-center, multiple-strength and single-dose phase I clinical study on cardiovascular MRI in patients with chronic kidney disease, aiming to investigate the effects and safety of multi-strength, single-dose at different time points, and to provide reference for clinical diagnosis and MRI enhancement.
