Primary purpose: BASIC_SCIENCE

Brief summary: The purpose of this study is to evaluate and compare the relative bioavailability of a single 0.6 mg tablet of Colcrys® (colchicine, USP) when crushed and sprinkled on applesauce (1 tablespoon) relative to the same dose given as an intact tablet to healthy subjects following an overnight fast. A secondary objective is to evaluate the safety and tolerability of this regimen in healthy volunteers. All study subjects will be monitored for adverse events throughout the study period.

Detailed description: The purpose of this study is to evaluate and compare the relative bioavailability of a single 0.6 mg tablet of Colcrys® (colchicine, USP) when crushed and sprinkled on applesauce (1 tablespoon) relative to the same dose given as an intact tablet to healthy subjects following an overnight fast. Sixteen healthy, non-smoking, non-obese, male and female volunteers between 18-55 years of age will be randomly assigned in a crossover fashion to receive each of two dosing regimens in sequence with a 14 day washout period between dosing periods. In each of the dosing periods, after an overnight fast, subjects will receive one intact Colcrys® 0.6 mg tablet (followed by 240 mL of water) or one Colcrys® 0.6 mg tablet crushed and sprinkled on 1 tablespoon of applesauce (followed by 240 ml of water) according to the randomization schedule. Blood samples will be drawn from all participants before dosing and for 48 hours post-dose at times sufficient to adequately define the pharmacokinetics of colchicine. Vital signs (blood pressure, heart rate, respiratory rate and temperature) will be measured prior to dosing, 1 hour ± 30 minutes post-dose and upon discharge from the clinical facility. Subjects will be monitored throughout their participation in the study for adverse reactions.
