About

The overall objective of this study is to evaluate the safety and diagnostic efficacy of Mangoral in liver MRI in participants with known or suspected focal liver lesions and severe renal impairment. The diagnostic efficacy of Mangoral will be assessed in terms of visualization of detected focal liver lesions in combined MRI (CMRI: combined Mangoral-enhanced and unenhanced MRI) compared to unenhanced MRI.

Full description

The overall objective of this multicenter, open-label, study is to evaluate the safety and diagnostic efficacy of Mangoral in participants with known or suspected focal liver lesions and severe renal impairment. Study treatment is a single oral dose of Mangoral (800 mg manganese chloride [II] tetrahydrate, 500 mg L-alanine, and 800 IU vitamin D3). Adult male and female participants with severe renal impairment or acute kidney injury and who are being evaluated for known or suspected focal liver lesions will be included. Primary diagnostic efficacy in terms of visualization of detected lesions will be evaluated centrally by 3 independent readers. Study MRIs will also be evaluated by the on-site radiologists for the assessment of secondary objectives and for clinical purposes.
