- Subject who has a history of peptic ulcer disease (PUD) with known aetiology must provide documentation by a gastroenterologist of the aetiology of the PUD and that effective treatment was provided with full eradication of ulcers and symptoms. For such subjects appropriate steps must also have been taken to minimize reoccurrence of risk (i.e. if PUD was nonsteroidal anti-inflammatory drug [NSAID] induced, the subject should no longer be taking NSAID medications; if cause was H. pylori, the subject should have been appropriately treated). Subjects with a history of PUD >10 years ago, without recurrence, may be included after discussion with the medical monitor even if documentation from treating physician is not available or aetiology unclear. See Section 6.3.6 for more details.
