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 and Day 5: 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 the last quantifiable time point (AUC0-t) of azacitidine following a single dose (Day 1) and multiple doses (Day 5) was calculated by the linear trapezoidal rule for participants with normal renal function and for participants with severe renal impairment.

Analysis population: Pharmacokinetic Population, consisting of all participants with evaluable plasma or urine concentration data for azacitidine. This analysis was performed for participants in the 2 treatment groups who received azacitidine treatment for 5 days.

Groups in this outcome

Normal RF: Azacitidine 75 mg/m^2

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

Severe RI: Azacitidine 75 mg/m^2

Participants with severe renal impairment (RI) received subcutaneous doses of azacitidine 75 mg/m\^2 on Days 1 to 5.

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

group Description
Comparison of AUC0-t after a single dose (Day 1) in participants with normal renal function and participants with severe renal impairment. Geometric means, ratio and 90% CI of ratio of geometric means are from an analysis of variance model with renal function group (normal and severe), visit (Day 1 and Day 5), renal function group by visit interaction as fixed effect, and patient nested within renal function group as a random effect on the nature log-transformed pharmacokinetic parameters
