Clinical Trial Summary

The 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.


Description:

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.

Outcome

Type Measure Description Time frame Safety issue
Other Correlation between the plasma clearance of MP-3180 and the plasma clearance of iohexol Blood samples were collected and analyzed using validated analytical methods. Mean concentrations over time were determined. 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 the following times after dosing: 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. Pre-dose and each time the participant voided up to 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 the following times after dosing: 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 the following times after dosing: 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 the following times after dosing: 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 the following times after dosing: 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 the following times after dosing: 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 the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose No
Secondary Incidence of adverse events An adverse event (AE) was defined as any untoward medical occurrence in a study subject after study drug administration and that did not necessarily have a causal relationship with this treatment. 1, 3, and 8 hours after dosing, and within 2 weeks after the final study dose Yes
Secondary Number of laboratory values that fall outside of pre-specified normal ranges Blood samples were collected and analyzed for hematology and clinical chemistry. Out of range values were documented. Pre-dose and within 2 weeks after the final study dose Yes
