P03277 Dose Finding Study in Central Nervous System (CNS) Magnetic Resonance Imaging (MRI)

The purpose of this study was to determine a safe and effective dose of a new gadolinium-based contrast agent (GBCA) P03277 based on the Contrast to Noise Ratio (CNR) when comparing with gadobenate dimeglumine (MultiHance®) at 0.1 mmol/kg body weight (BW). Contrast to Noise Ratio (CNR), a well-known quantitative parameter directly related to contrast medium/GBCA efficacy, was chosen as the primary endpoint in order to have a precise determination of P03277 clinical dose. This was a multi-center, international, prospective, double-blind, randomized, controlled, parallel dose groups, cross-over with comparator study in male and female subjects presenting with known or highly suspected focal areas of disruption of the Blood Brain Barrier including at least one expected enhancing lesion of minimum 5 mm, who were scheduled to undergo a routine contrast-enhanced Magnetic Resonance Imaging (MRI) of Central Nervous System.
