16The purpose of this study was to investigate the pharmacokinetics of MP-3180 (1 µmol/kg) compared to the pharmacokinetics of iohexol (5 mL of a 300 mg iodine (I)/mL solution) in healthy adult participants. The secondary objective was to evaluate the safety and tolerability of MP-3180 in healthy adult participants.
Single-dose pharmacokinetics were characterized in sixteen (16) healthy, adult male participants in this Phase 1, open-label study following the administration of a single, intravenous 1 µmol/kg dose over 2 minutes followed by 10 mL saline under fasting conditions. Iohexol (Omnipaque-300, 5 mL of a 300 mg I/mL solution) was also administered over 2 minutes followed by 10 mL of saline. The pharmacokinetics of MP-3180 and iohexol was assessed by statistical comparison of pharmacokinetic parameters derived from plasma concentration-time curves and urine recovery data.
MP-3180 (1 µmol/kg or 0.372 mg/kg) (fluorescent tracer agent) was administered by IV injection (2.5 mL to 3.5 mL for participant weights of 70 kg to 91 kg) over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.
Iohexol (Omnipaque 300, 5 mL) was administered by IV injection over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.
MP-3180 (1 µmol/kg or 0.372 mg/kg) was administered by IV injection (2.5 mL to 3.5 mL for participant weights of 70 kg to 91 kg) over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes. The iohexol comparator (Omnipaque 300, 5 mL) was then administered by IV injection over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.
