Pharmacokinetics of MP-3180 and Use of Noninvasive Fluorescence Detection Device in Healthy Volunteers

MP-3180 0.5 µmol/kg (0.186 mg/kg) dose (fluorescent tracer agent) was administered by IV injection over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.

MP-3180 1 µmol/kg (0.186 mg/kg) dose (fluorescent tracer agent) was administered by IV injection over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.

MP-3180 2 µmol/kg (0.744 mg/kg) dose (fluorescent tracer agent) was administered by IV injection over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.

MP-3180 4 µmol/kg (1.488 mg/kg) dose (fluorescent tracer agent) was administered by IV injection over 2 minutes, followed by a 10 mL saline flush IV over 2 minutes.

The Optical Renal Function Monitor (ORFM) investigational device noninvasively monitors fluorescent light emission from an exogenous tracer agent over time. Prior to administration of MP-3180 and iohexol, ORFM sensor probes were affixed to each of the participants via standard adhesive pads to four locations: forehead, sternum, upper inner arm, side trunk. The administration of the MP-3180 infusion and iohexol infusion occurred at least 15 minutes after the start of the data acquisition software.

Iohexol (Omnipaque 300, 5 mL) (comparator agent) was administered by IV injection over 2 minutes after MP-3180 injection, followed by a 10 mL saline flush IV over 2 minutes.
