Clinical Trial Summary

The purpose of this early feasibility study was to investigate the pharmacokinetics of MP-3180 administered in rising doses and to evaluate the use of the Optical Renal Function Monitor (ORFM), an investigational noninvasive fluorescence detection device.


Description:

This was an open-label, rising single-dose study to investigate the pharmacokinetics of the investigational agent, MP-3180, and to evaluate the use of the Optical Renal Function Monitor (ORFM), an investigational noninvasive fluorescence detection device. Single-dose pharmacokinetics at four dose levels were evaluated following the administration of a single, intravenous dose of MP-3180. Iohexol was also administered followed by saline. Prior to administration of MP-3180 and iohexol, ORFM sensor probes were affixed to four locations on the body of each participant. The noninvasive fluorescent signal from MP-3180 was measured using the ORFM investigational device continuously for approximately four hours post MP-3180 administration. For the determination of the pharmacokinetic disposition of MP-3180 and iohexol, blood samples were collected from each participant provided the individual completed all blood collections in the study. The pharmacokinetics of MP-3180 and iohexol were assessed by statistical comparison of pharmacokinetic parameters derived from plasma concentration-time curves and urine recovery data.

Intervention

Drug:
Below target dose MP-3180
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.
At target dose MP-3180
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.
2 times above target dose MP-3180
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.
4 times above target dose MP-3180
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.
Device:
ORFM prototype
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.
Other:
Iohexol comparator
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.

Outcome

Type Measure Description Time frame Safety issue
Other Correlation between MP-3180 fluorescence intensity and MP-3180 concentration in plasma Blood samples were collected and analyzed using validated analytical methods. The fluorescence intensity at the time of the blood sampling was compared to plasma concentrations. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary Total plasma clearance of MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. Total plasma clearance (the volume of plasma cleared of the drug over time) was calculated as: Clp = Dose/ AUC8. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary Renal clearance of MP-3180 and iohexol Urine samples were collected pre-dose (time 0) and 5 mL urine samples were collected each time the subject voided.
The total volume of urine excreted was recorded until 12 hours post-dose, and analyzed using validated analytical methods. Renal clearance (the volume of plasma cleared of the drug by the kidneys over time) was calculated as: CLr
= Ae/ AUClast, where Ae is the cumulative amount of analyte excreted in urine over the sampling interval.
60, 120, 240, 360, 600 and 720 minutes post-dose No
Primary Maximum Plasma Concentration (Cmax) for MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. Maximum plasma concentration (Cmax; measured in ng/mL) was directly determined from the concentration-time data. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary Time to Maximum Plasma Concentration (Tmax) for MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. The time to maximum plasma concentration (Tmax; measured in hours) was directly determined from the concentration-time data. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary The terminal rate constant for MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. The terminal rate constant (?z) was determined by linear regression of the terminal linear phase of the log plasma concentration-time profile. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration for MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. The area under the plasma concentration-time curve (ng*hr/mL) was estimated from time 0 to the last measurable concentration using noncompartmental analyses. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary Area under the plasma concentration-time curve from time zero to infinity for MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. The area under the plasma concentration-time curve (ng*hr/mL) from time 0 to infinity was calculated as: AUC8 = AUClast + LQC/?z where LQC is the predicted concentration (based on the terminal regression) at the time of the last measurable concentration. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Primary The elimination half-life of MP-3180 and iohexol Blood samples were collected and analyzed using validated analytical methods. The elimination half-life (the time required for the concentration of the drug to reach half of its original value) was calculated as t1/2 ?z= ln(2)/ ?z. Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
