简要总结
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.
详细描述
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.

Time to Maximum Plasma Concentration (Tmax) for MP-3180 and iohexol
时间窗: Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose
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.
The terminal rate constant for MP-3180 and iohexol
时间窗: Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose
Blood samples were collected and analyzed using validated analytical methods. The terminal rate constant (λz) was determined by linear regression of the terminal linear phase of the log plasma concentration-time profile.

时间窗: Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose
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.
Total plasma clearance of MP-3180 and iohexol
时间窗: Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose
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/ AUC∞.
Maximum Plasma Concentration (Cmax) for MP-3180 and iohexol
时间窗: Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose
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.
Area under the plasma concentration-time curve from time zero to infinity for MP-3180 and iohexol
时间窗: Pre-dose and 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose
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: AUC∞ = AUClast + LQC/λz where LQC is the predicted concentration (based on the terminal regression) at the time of the last measurable concentration.
Renal clearance of MP-3180 and iohexol
时间窗: 60, 120, 240, 360, 600 and 720 minutes post-dose
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.
