The introduction of celecoxib (Celebrex, Figure 1; GD Searle and Co) as the first cyclooxygenase (COX)2 selective inhibitor in the US and the expected introduction of rofecoxib (Vioxx; Merck and Co Inc) as the first COX2 inhibitor with an acute pain indication, has prompted interest in this class of drugs as a possible therapeutic improvement on dual COX1/COX2 inhibitor NSAIDs, currently on the market. Recognition that the COX-2 enzyme may have a broader role than pain and inflammation has led to studies investigating the efficacy of COX-2 inhibitors for Alzheimer's disease (AD), stroke, cardiovascular disease and colon cancer. Speakers at the second annual conference sponsored by IBC, addressed issues ranging from the basic concepts of COX2 specificity versus selectivity, pathways and regulatory factors related to COX2 expression, the principles underlying the possible broad implications of the COX2 mechanisms, as well as summaries of recently completed clinical trials supporting the clinical efficacy and safety of COX2 inhibitors in humans. The timeliness of this meeting is emphasized by the recent approval of rofecoxib by the FDA Arthritis Advisory panel and the initial reports in the media of toxicity attributed to celecoxib. Preclinical and limited clinical data presented suggest possible therapeutic roles for selective COX2 inhibitors in neurodegeneration due to both AD and stroke, the prevention and treatment of colon cancer, prevention of premature labor, as well as pain and inflammation.
