The aim of this study is to compare a PPI (esomeprazole) plus a COX-2 inhibitor (celecoxib) with a PPI plus a nonselective NSAID (naproxen) in preventing recurrent ulcer bleeding in arthritis patients with a history of ulcer. The investigators hypothesized that among patients with a history of ulcer bleeding who receive prophylaxis with a PPI, celecoxib would be superior to naproxen for the prevention of recurrent ulcer bleeding irrespective of concomitant use of aspirin.

Clinical Details

Official title: A Double-blind Randomized Comparison of Esomeprazole Plus Celecoxib Versus Esomeprazole Plus Naproxen for Prevention of Recurrent Ulcer Bleeding in Arthritis Patients (NSAID#8 Study)

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Recurrent ulcer bleeding within 78 weeks according to pre-specified criteria

Secondary outcome: Cardiovascular events

Detailed description: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly consumed drugs worldwide for the relief of pain and arthritis. However, the use of NSAIDs increases the risk of ulcer bleeding by 4-fold. Current evidence indicates that combination of conventional NSAIDs and a proton pump inhibitor (PPI) reduces the risk of ulcer complications. The alternative strategy is to replace conventional, non-selective NSAIDs with NSAIDs selective for cyclooxygenase-2 (COX-2 inhibitors). Recently, there are concerns about the cardiovascular safety of COX-2 inhibitors and conventional NSAIDs. Because of such concern, patients requiring anti-inflammatory analgesics who have cardiovascular risk factors (e. g. smoking, hypertension, hyperlipidemia, diabetes) should receive prophylactic low-dose aspirin. However, concomitant low-dose aspirin negates the gastric sparing effect of COX-2 inhibitors and augments the gastric toxicity of nonselective NSAIDs. Thus, gastroprotective agents such as PPIs should be co-prescribed to patients with high ulcer risk who are taking aspirin plus a COX-2 inhibitor or a nonselective NSAID.
