Blinded Cross-Over Bioequivalence (BE) Trial of Luitpold Azacitidine vs Vidaza

American Regent, Inc.38 enrolled

Overview

The purpose of this study is to assess the bioequivalence of subcutaneous Vidaza® and subcutaneous Luitpold Azacitidine pharmacokinetics and to assess the comparative safety of subcutaneous Vidaza® versus subcutaneous Luitpold Azacitidine.

To assess the bioequivalence of Vidaza® and Luitpold Azacitidine pharmacokinetics, in terms of Maximal Concentration (Cmax), Area Under the Curve From Time Zero to the Time of Last Quantifiable Concentration (AUC 0-t), and Area Under the Curve From Time Zero Extrapolated to Infinity (AUC 0-∞), following SC administration. To assess the comparative safety of Vidaza® versus Luitpold Azacitidine during the 2 day study period.

Outcomes

Primary Outcomes

Area Under the Curve (AUC) From Time Zero to the Time of Last Quantifiable Concentration (AUC 0-t)

The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample; AUC 0-t is defined as AUC from time 0 to the last data point

Time frame: 0.125, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 hours after dosing on days 1 and 2.

Area Under the Curve From Time Zero Extrapolated to Infinity (AUC 0-∞)

The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample. AUC 0-∞ is defined as area under the concentration vs. time curve from zero to infinity.

Time frame: 0.125, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 hours after dosing on days 1 and 2

Observed Maximal Concentration (Cmax)

Cmax refers to the highest measured drug concentration which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample.

Time frame: 0.125, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 hours after dosing on days 1 and 2
