Participant Flow

Twenty-four (24) healthy, non-smoking, male and female volunteers, consisting of volunteers from the community at large, were enrolled in the study.

41 subjects were screened, 11 were screen failures, 4 had schedule conflicts, 1 was transferred to a different study, and 1 was not needed

Colchicine Alone / With Cyclosporine
\[All subjects received each of the study treatments.\] Each subject received one 0.6 mg colchicine tablet on Day 1 at 7:15 a.m. after an overnight fast, followed by a washout period of 14 days. Then, on Day 15, each subject received both one 0.6 mg colchicine tablet and one 100 mg cyclosporine capsule at 7:15 a.m. after an overnight fast of at least 10 hours.
