NCT00506883

Brief Summary

This study is a multicenter, randomized, double-blind, placebo-controlled, parallel group, dose-comparison to determine the efficacy and safety of a standard-dose of colchicine (4.8 mg) versus low-dose colchicine (1.8 mg) or placebo for acute gout flares.

Outcome Measures

Primary Outcomes (1)

  • Responders

    Responders were defined as patients who achieved a ≥ 50% reduction in target joint pain score from baseline at 24 hours without using rescue drug, using an 11 point scale from 0 to 10, with 10 being the worst pain imaginable after beginning therapy.

    24 hours after baseline

Study Arms (3)

High Dose Colchicine

EXPERIMENTAL

After confirmation of a gout flare, patients were to begin standard dosing of colchicine 4.8mg (two capsules (1.8mg) initially followed by additional one capsule doses (0.6mg) every hour for an additional 6 doses).

Drug: High Dose Colchicine (4.8 mg total dose)

Low Dose Colchicine

EXPERIMENTAL

Within 12 hours of a confirmed gout flare, patients were to begin the low dose colchicine regimen consisting of a total dose of 1.8 mg - two colchicine capsules initially (1.2 mg)followed an hour later by a single additional capsule of active drug(0.6 mg)then by 5 additional hourly doses of an identical looking placebo capsules

Drug: Low Dose Colchicine (1.8mg total dose)

Placebo

PLACEBO COMPARATOR
Other: Placebo Control

Interventions

At randomization, patients were given an identical looking blister pack containing (8) over encapsulated colchicine 0.6 mg tablets identical in appearance to placebo capsules. Patients were instructed to take 2 capsules initially (1.2 mg) followed by an additional capsule (0.6 mg) every hour for a total of six additional doses (total colchicine dose 4.8 mg) beginning within 12 hours of onset of a qualifying gout flare as confirmed by calling the gout flare call center.

Also known as: Colcrys TM, Colchicine 0.6 mg
High Dose Colchicine

At randomization, patients were given an identical looking blister pack containing (3) over encapsulated colchicine 0.6 mg tablets identical in appearance to placebo capsules and five placebo capsules. Patients were instructed to take 2 capsules initially (0.6 mg x 2) followed by an additional capsule every hour for a total of six additional doses (one active (0.6 mg) and 5 placebo capsules), a total colchicine dose = 1.8 mg) beginning within 12 hours of onset of a qualifying gout flare as confirmed by calling the gout flare call center

Also known as: Colcrys TM, Colchicine 0.6 mg
Low Dose Colchicine

At randomization, patients were given an identical looking blister pack containing (8) placebo capsules identical in appearance to the study drug. Patients were instructed to take 2 capsules initially followed by an additional capsule every hour for a total of six additional doses beginning within 12 hours of onset of a qualifying gout flare as confirmed by calling the gout flare call center.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients of either gender and of any race ≥18 years of age.
  • If female, patients must be postmenopausal as evidenced by lack of menses for ≥12 consecutive months.
  • Patients must present with a confirmed diagnosis of gout.
  • Patients must have experienced ≥2 acute gouty arthritic attacks in the 12 months prior to randomization.
  • Patients on urate lowering therapy must be on a stable dose and schedule with no changes in therapy for 4 weeks prior to randomization and expected to remain on a stable regimen during study participation.
  • Patients must be willing to adhere to the study schedule and the protocol requirements.
  • Patients must be willing and able to give written informed consent. A HIPAA and/or state privacy consent must also be signed.

You may not qualify if:

  • Patients with acute polyarticular gout (\>4 joints).
  • Patients who have experienced \>2 acute gouty arthritic attacks per month, or \>12 attacks overall, in the 6 months prior to randomization.
  • Patients with arthritis due to any cause other than gout that may confound any study assessments per Investigator discretion.
  • Patients with a history of myocardial infarction, unstable angina, cerebrovascular events, or coronary artery bypass grafting within the previous 6 months prior to screening.
  • Patients with active myeloid leukemia, obstructive gastrointestinal cancer, or metastatic cancer.
  • Patients with chronic renal dysfunction (creatinine clearance \<60 mL/min as estimated with the Cockcroft Gault formula).
  • Patients with chronic hepatic dysfunction.
  • Patients with a history of alcohol or substance abuse within the 12 months prior to randomization.
  • Patients who have any concomitant illness or other finding that, in the opinion of the Investigator, would confound the study data or place the patient at unacceptable risk if the patient were to participate in the study, or that would require frequent adjustments in concomitant medications during the course of the study.
  • Patients using systemic corticosteroid, cyclosporine, adalimumab, etanercept, infliximab, anakinra, abatacept, mycophenolate, azathioprine, anticoagulants (warfarin, heparin, low molecular weight heparin \[LMWH\], antithrombin agents, thrombin inhibitors, or selective Factor Xa inhibitors \[note, use of aspirin ≤325 mg/day is allowed\]), or chronic use of non steroidal anti inflammatory drugs (NSAIDs), acetaminophen, tramadol, and other analgesics such as opiates at screening
  • Use of any investigational drug within 30 days prior to randomization.
  • Patients currently participating in another research study or anticipated to enroll in such during participation in this study.
  • Patients for whom informed consent cannot be obtained.
  • Patients who have previously been randomized into this study and begun ingestion of study drug.
