Change from baseline in Electrocardiograms [ Time Frame: Up to 80 weeks. ] [ Designated as safety issue: Yes ]
Change from baseline in Vital signs [ Time Frame: Up to 80 weeks. ] [ Designated as safety issue: Yes ]
Change from baseline in Serum gastrin [ Time Frame: Up to 80 weeks. ] [ Designated as safety issue: Yes ]
Change from baseline in Pepsinogen I and II [ Time Frame: Up to 80 weeks. ] [ Designated as safety issue: Yes ]
Recurrence rate of gastric or duodenal ulcer [ Time Frame: Up to 80 weeks. ] [ Designated as safety issue: No ]
