This trial is a Phase 2, randomized, controlled study to compare the degree of mucosal injury after the oral administration of an investigational product, PL2200, and a marketed 325 mg immediate-release aspirin product. Each group will be treated with either an immediate-release aspirin tablet or PL2200 capsule at 325 mg per day for 6 weeks, and evaluated via an endoscope for any gastrointestinal injury that may have been caused by study medication.
