Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
In 2007 between 4 April and 3 December 813 patients were screened at 74 US treatment centers. 72 centers randomized a total 575 patients. 185 patients at 54 centers had a qualifying gout flare and 184 are included in the ITT population. The remaining, 390 patients had no flare or had a flare that failed to qualify for study medication use

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
813 patients with confirmed diagnosis of gout based on American College of Rheumatology criteria were screened. 575 patients qualified and were randomized within 28 days of screening. 238 patients failed screening. The vast majority, 235 (98.7%) failed to meet inclusion/exclusion criteria.

Reporting Groups
  Description
High Dose Colchicine(MPC-004) Standard Dose Colchicine - 4.8 mg (total dose): 1.2 mg of oral colchicine (2 x 0.6 mg tablets) at onset of confirmed gout flare followed by 0.6 mg oral colchicine (1 x 0.6 mg tablet) every hour for 6 hours. All doses were over encapsulated to mimic the appearance of the placebo.
Low Dose Colchicine(MPC-004) Low Dose Colchicine - 1.8 mg (total dose): 1.2 mg of oral colchicine (2 x 0.6 mg tablets) at onset of confirmed gout flare followed by 0.6 mg oral colchicine (1 x 0.6 mg tablet) after 1 hours followed by placebo every hour thereafter hourly for 5 additional hours. All active doses were over encapsulated to mimic the appearance of the placebo.
Placebo Two oral placebo capsules at onset of a confirmed gout flare followed by 1 oral placebo capsule every hour for an additional 6 hours.
