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 |
