Eligibility criteria:

        Inclusion Criteria:

          -  Subjects must present with confirmed diagnosis of gout, meeting the American College
             of Rheumatology (ACR) 1977 preliminary criteria for the classification of acute
             arthritis of primary gout

          -  Subjects must have experienced at least one (1) acute gouty arthritic attack in the 12
             months prior to randomization

          -  Presence of acute gout flare for no longer than 3 days at Visit 2

          -  Pain intensity at inclusion (Visit 2) of 7-10 on 11-point PI-NRS (defined as severe
             gout flare for this study)

          -  All patients should not have contraindications for Colchicine use

          -  Subjects with a history of intolerance to NSAIDs (Checklists Checklist 1)

          -  Subjects with significant medical contraindication to NSAIDs (Checklist 2)

          -  Subjects with past failure of NSAIDs to control acute gouty arthritis attacks in the
             previous 12 months (Checklist 3)

          -  Regarding significant medical contraindication to NSAIDs or past failure of NSAIDs to
             control acute gouty arthritis attacks in the previous 12 months (i.e. refractoriness
             to NSAIDs) the patient must meet one of below criteria:

               1. At least one historical episode within the previous 12 months of being refractory
                  or intolerant to NSAIDs that makes the physician concerned to use NSAIDs for a
                  subsequent acute gout attack

               2. The current (referring) physician judgment is that NSAIDs are not appropriate for
                  treating the patient's gouty arthritis flare which may be due to changes in
                  patient status such as worsening co-morbid conditions or co-medications (e.g., GI
                  tract disease, renal insufficiency, hypertension, fluid retention, concurrent use
                  of diuretics and/or an angiotensin converting enzyme inhibitor or angiotensin
                  receptor blocker, especially in CKD)

          -  Subjects must be willing and able to give written informed consent. A HIPAA and/or
             state privacy consent must also be signed

          -  Subjects must be able to swallow tablets

             30 days prior to screening

             prior to randomization (historical lab results are acceptable).

             infectious/septic arthritis, acute polyarticular gout (4 or more joints), with

             attacks overall, in the 6 months prior to randomization

          -  Uncontrolled hypertension (>160/90 mmHg seated) (if the first set of BP assessment
             meets the definition of uncontrolled hypertension, a second set of BP assessments may
             be performed after the patient has rested for at least 30 min. If the second set of BP
             assessments does not meet the definition of uncontrolled hypertension the patient will
             be eligible for participation)
