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

Phase 1

Completed

Conditions: Myelofibrosis
Myelodysplastic Syndrome
Chronic Myeloid Leukemia
Chronic Lymphocytic Leukemia

Brief Summary: 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.

Detailed Description: 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.

Primary Outcome Measures

Name	Time	Method
Area Under the Curve (AUC) From Time Zero to the Time of Last Quantifiable Concentration (AUC 0-t)	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.	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
Area Under the Curve From Time Zero Extrapolated to Infinity (AUC 0-∞)	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	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.
Observed Maximal Concentration (Cmax)	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	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.
