NCT ID: NCT01040845

Last Updated: 2010-01-05

Oral Contraceptive With Placebo Then Colchicine
\[All subjects received each of the two study treatments in a randomly assigned sequence of two dosing cycles.\] On the mornings of Days 1 to 20 of each cycle, each subject took one active tablet of Ortho-Novum 1/35. On Days 8 to 20, subjects additionally took one capsule of study drug (matching placebo capsule during the first cycle or over-encapsulated colchicine tablets 0.6 mg during the second cycle) twice daily. On Day 21 of each cycle, subjects received a single dose of study drug and a single active tablet of Ortho-Novum 1/35; then, 12 hours later, they received a second dose of study drug with a light snack. Inert Ortho-Novum 1/35 tablets were taken on Day 22 (after breakfast and the last blood sample), and then daily on Days 23 to 28.
