Design outcomes

Primary

MeasureTime frame
Primary Objective: To characterize the pharmacokinetic profiles of Azathioprine and 6-Mercaptopurine following a single dose of Azathioprine 50 mg Tablets under fasting condition and to assess the bioequivalence of Azathioprine 50 mg Tablets between test and reference products. Secondary objective: To assess the safety and tolerability of the test and reference products in adult human patients with Rheumatoid Arthritis (RA) who are on a regimen of oral Azathioprine under fasting condition.Timepoint: 0.00 and post dose administration at 0.16 (10 min), 0.33 (20 min), 0.50 (30 min), 0.67 (40 min), 0.83 (50 min), 1.00 (60 min), 1.16 (1 hour and 10 min), 1.33 (1 hour and 20 min), 1.67 (1 hour and 40 min), 1.83 (1 hour and 50 min), 2.00 (120 min), 2.33 (2 hour and 20 min), 2.67 (2 hour and 40 min), 3.00 (180 min), 4.00, 5.00, 6.00 and 8.00 hours post dose in each period.

Secondary

MeasureTime frame
Secondary objective: To assess the safety and tolerability of the test and reference products in adult human patients with Rheumatoid Arthritis (RA) who are on a regimen of oral Azathioprine under fasting condition.Timepoint: Medical Examination will be performed at the time of check-in, at the time of last sampling time point of period I and at the time of check-out 24.00 hours post dose of period-II. Vital signs (Blood pressure, pulse rate, respiratory rate and body temperature) will be recorded at check in, pre dose in each period and at checkout of period II.
