A Study of a Gadolinium-Based Contrast Agent (GBCA) for Adults Undergoing Magnetic Resonance Imaging (MRI) for Known or Highly Suspected Body Parts (Non-Central Nervous System) Lesions
China306 participantsStarted 2025-11-14
Plain-language summary
The purpose of this study is to evaluate the efficacy of HRS-9231 for Magnetic Resonance Imaging (MRI) of body regions excluding the Central Nervous System (CNS) in patients undergoing MRI examinations, using the patient's own unenhanced MRI images as a control; to demonstrate that the efficacy of HRS-9231 is not inferior to gadobutrol for lesion visualization in body MRI; to evaluate the safety of HRS-9231 for body MRI; and to explore the population pharmacokinetic characteristics of HRS-9231 in subjects undergoing body MRI examinations.

Inclusion criteria
✓. Provide written informed consent, be willing and able to comply with study requirements.
✓. Age ≥18 years, male or female.
✓. Subjects who are scheduled to undergo a contrast-enhanced MRI (including MRA) examination and who, within 12 months prior to signing the informed consent form, have had imaging examinations that identified at least one known or highly suspected region of enhancement abnormality or lesion in the body.
Exclusion criteria
✕. Investigator judges unstable clinical condition or comorbidities that may affect MRI image comparability or study parameters.
✕. Severe renal impairment (baseline eGFR \< 30 mL/min/1.73m²) before first dose; acute kidney injury regardless of eGFR.
✕. Acute kidney injury, irrespective of eGFR levels.
✕. Contraindication to MRI or gadolinium contrast agents.
✕. History of severe allergic reactions to drugs, contrast agents, or other allergens.
What they're measuring
1
To compare the lesion visualization scores (border delineation) of HRS-9231-enhanced with gadobutrol-enhanced MRI.
Timeframe: Day 1 after procedure.
2
To compare the lesion visualization scores (internal morphology) of HRS-9231-enhanced with gadobutrol-enhanced MRI.
Timeframe: Day 1 after procedure.
3
To compare the lesion visualization scores (degree of contrast enhancement) of HRS-9231-enhanced with gadobutrol-enhanced MRI.
