Area Under the Plasma Concentration-time Curve From Time Zero to Infinity

Pharmacokinetics and Safety Study of Azacitidine in Cancer Patients With and Without Impaired Renal Function · Source last updated 2019-11-19

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: GEOMETRIC_MEAN
Unit: ng*hr/mL
Interval / dispersion: Geometric Coefficient of Variation
Time frame: Day 1 at predose, 5, 15, 30, 45 minutes and 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, and 8 hours post-dose

What was measured

The area under the plasma concentration-time curve from time zero to infinity (AUC0-inf) for azacitidine after a single dose, calculated by the linear trapezoidal rule and extrapolated to infinity according to the following equation: AUC0-inf = AUC0-t + (Ct/ke), where Ct is the last quantifiable concentration and ke = elimination rate constant.

Analysis population: Pharmacokinetic Population, consisting of all participants with evaluable plasma or urine concentration data for azacitidine. This analysis was performed for participants with normal renal function only.

Groups in this outcome

Azacitidine 25 mg/m^2

Participants with normal renal function (defined as creatinine clearance \> 80 mL/min/1.73m\^2) received a single subcutaneous dose of azacitidine 25 mg/m\^2 on Day 1.

Azacitidine 50 mg/m^2

Participants with normal renal function received a single subcutaneous dose of azacitidine 50 mg/m\^2 on Day 1.

Azacitidine 75 mg/m^2

Participants with normal renal function received subcutaneous doses of azacitidine 75 mg/m\^2 on Days 1 to 5.

Azacitidine 100 mg/m^2

Participants with normal renal function received a single subcutaneous dose of azacitidine 100 mg/m\^2 on Day 1.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.

Ratio of geometric mean is calculated as Azacitidine 50 mg/m\^2 / Azacitidine 25 mg/m\^2 and expressed as a percentage.
group Description
Geometric means, ratio and 90% CI of ratio of geometric means are from one way analysis of variance models on the nature log-transformed dose-normalized AUC0-inf, obtained on Day 1. Azacitidine 25 mg/m\^2 is the reference group for comparisons.
