NCT06010537

Brief Summary

This is a contrast-enhanced magnetic resonance imaging (MRI) study conducted on a single-administration of polyglucose superparamagnetic iron oxide injection. Two dose groups are set up in this study, 2.5 mg/kg and 3 mg/kg, and two subjects in each group received the test drug for safety evaluation.

  • Use of any prescription medication, over-the-counter medication, any vitamin product or herbal remedy within 14 days prior to dosing;
  • The need to use tobacco, alcohol and caffeinated beverages, or certain foods that may affect metabolism (e.g., grapefruit, grapefruit juice, etc.) during the trial period, or a significant change in dietary or exercise habits prior to the trial, or any other factor that affects the absorption, distribution, metabolism, or excretion of the drug;
  • Use of an investigational drug or participation in a clinical trial of a drug within 2 months prior to dosing;
