Gout
About this trial
This is an interventional prevention trial for Gout focused on measuring Gout, Chronic gout, Gouty arthritis, Gout flares
Eligibility Criteria
Core study
Inclusion Criteria:
- Signed written informed consent before any study procedure is performed.
- History of at least 2 gout flares in the year prior to Screening (Visit 1, based on patient history), thus, candidates for initiating uric acid lowering therapy.
- Confirmed diagnosis of gout meeting the American College of Rheumatology (ACR) 1977 preliminary criteria for the classification of arthritis of primary gout.
- Body Mass Index (BMI) ≤ 40 kg/m^2.
- Willingness to initiate allopurinol therapy as urate lowering agent for their gout therapy or having initiated allopurinol therapy within ≤ 1 month before Screening (Visit 1) or willing to re-initiate allopurinol therapy if this was stopped > 2 months before Screening (Visit 1) for reasons different to toxicity/ intolerance or lack of efficacy.
Exclusion Criteria:
- Acute gout flare within 2 weeks of Screening (Visit 1) and during the Screening period.
- History of allergy or contraindication to colchicine or allopurinol.
- History of intolerance to allopurinol or to oral colchicine in appropriate dose for prophylactic use.
- History of bone marrow suppression.
- Absolute or relative contraindication to both naproxen and oral prednisolone/ prednisone.
Extension study
Inclusion criteria:
- Patients who completed the core study. A patient is defined as completing the core study if he/she completed the study up to and including the last visit (Visit 9).
- Patients who have signed a written informed consent before any trial procedure is performed.
Exclusion Criteria:
- Patients for whom continuation in the extension study is not considered appropriate by the treating physician.
- Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive pregnancy test (serum or urine).
Other protocol-defined inclusion/exclusion criteria applied to the study.
