Background/Aims: Cyclooxygenase-2 (COX-2) may play an important role in the neuropathology of Alzheimer's disease ( AD). The efficacy and safety of celecoxib ( 200 mg bid), a COX-2 selective inhibitor, were assessed in patients >= 50 years with established mild-to-moderate AD to determine whether treatment was effective in retarding deterioration of cognitive function. Methods: This was a 52-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group study. The primary efficacy end points were the change from baseline to week 52 in the Alzheimer's Disease Assessment Scale-Cognitive Behavior (ADAS-cog) composite score and the week 52 Clinician's Interview-Based Impression of Change Plus (CIBIC+). Results: At 52 weeks, change in ADAS-cog scores from baseline was similar for placebo and celecoxib 200 mg bid groups (5.00 and 4.39, respectively). CIBIC+ scores were also similar (4.83 and 4.92). Two extension studies were conducted but were terminated early based on these efficacy results. Safety data from all 3 studies indicated that celecoxib was generally well-tolerated. Conclusion: Celecoxib 200 mg bid did not slow the progression of AD in this study, and the occurrence of adverse events was as expected for an elderly population with a complex chronic medical condition.
