Cardiovascular Safety of Febuxostat and Allopurinol in Participants With Gout and Cardiovascular Comorbidities (CARES) — CARES  

Cardiovascular Disease Clinical Trial

Official title: A Multicenter, Randomized, Active-Control, Phase 3B Study to Evaluate the Cardiovascular Safety of Febuxostat and Allopurinol in Subjects With Gout and Cardiovascular Comorbidities

Status Completed

Clinical Trial Summary

The purpose of this study is to see whether subjects with gout who receive febuxostat or allopurinol for up to 9 years have a higher rate of serious heart and blood vessel complications (major cardiovascular events).

Clinical Trial Description

The drug tested in this study was called Febuxostat (TMX-67). Febuxostat compared with allopurinol was evaluated for the cardiovascular (CV) safety in people with gout and significant CV comorbidities.

The study enrolled 6198 patients. Participants with a diagnosis of gout were enrolled in a 1:1 ratio to receive either:

• Febuxostat

• Allopurinol

Participants received febuxostat 40 mg or 80 mg for the study depending on their serum uric acid levels were either <6.0 mg/dL or ≥6.0 mg/dL during specified visits. Allopurinol 200 mg to 400 mg (for moderate renal impairment),or 300 mg to 600 mg (for normal and mild renal impairment), increased in 100 mg increments each month until serum uric acid was <6.0 mg/dL was received.

This multi-center trial was conducted in Canada, Mexico and United States. The overall time to participate in this study was approximately 7 years (84 months). Participants made multiple visits to the clinic and were also contacted through the telephone. ;
