The total volume of urine excreted was recorded until 12 hours post-dose, and was 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.
Correlation Between the Transdermal Fluorescence Intensity of MB-102 as Measured by the Brilliance Device and Plasma Concentration of MB-102 at Each Time Point in the Renal Excretion Phase in Participants With Normal-CKD Stage 2 Renal Function Pre-dose (time 0) and 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, and 480 minutes post dose Blood samples were collected pre-dose (time 0) and at 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, and 480 minutes post dose, and were analyzed using validated analytical methods. Transdermal fluorescence intensity at the time of blood sampling as measured by the Brilliance device was documented, and the correlation between the transdermal fluorescence intensity of MB-102 as measured by the Brilliance device and the plasma concentration of MB-102 at each time point in the renal excretion phase was calculated.
The Terminal Rate Constant for MB-102 Pre-dose and 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) minutes post dose. Blood samples were collected pre-dose (time 0) and at 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) minutes post dose, and were 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.
Correlation Between the Transdermal Fluorescence Intensity of MB-102 as Measured by the Quantum Leap Device and Plasma Concentration of MB-102 at Each Time Point in the Renal Excretion Phase Pre-dose (time 0) and 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) minutes post dose Blood samples were collected pre-dose (time 0) and at 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) minutes post dose, and were analyzed using validated analytical methods. Transdermal fluorescence intensity at the time of blood sampling as measured by the QuantumLeap device was documented, and the correlation between the transdermal fluorescence intensity of MB-102 as measured by the QuantumLeap device and the plasma concentration of MB-102 at each time point in the renal excretion phase was calculated.
Number of Participants With Adverse Events Related to the Use of the Radiance Device From the time of dosing through the follow-up visit, up to 10 days The number of participants with adverse events related to the use of the Radiance device was documented.
Number of Participants With Adverse Events Related to the Use of the Brilliance Device From the time of dosing through the follow-up visit, up to 10 days The number of participants with adverse events related to the use of the Brilliance device was documented.
Renal Clearance of MB-102 Pre-dose and each time the participant voids up to 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 was 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.
Correlation Between the Transdermal Fluorescence Intensity of MB-102 as Measured by the Brilliance Device and Plasma Concentration of MB-102 at Each Time Point in the Renal Excretion Phase in Participants With CKD Stage 3-4 Renal Function Pre-dose (time 0) and 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) and 960, 1440, 1920, 2400, and 2880 (±30 min) minutes post dose Blood samples were collected pre-dose (time 0) and at 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) and 960, 1440, 1920, 2400, and 2880 (±30 min) minutes post dose, and were analyzed using validated analytical methods. Transdermal fluorescence intensity at the time of blood sampling as measured by the Brilliance device was documented, and the correlation between the transdermal fluorescence intensity of MB-102 as measured by the Brilliance device and the plasma concentration of MB-102 at each time point in the renal excretion phase was calculated.
