Primary Outcome Measures:
  • Proportion of subjects who develop endoscopically-diagnosed upper gastrointestinal ulcers. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The proportion of subjects who develop endoscopically-diagnosed gastric ulcers during the 24-week Treatment Period. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • The proportion of subjects who develop endoscopically-diagnosed duodenal ulcers during the 24-week Treatment Period. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • The incidence rate of NSAID-associated serious gastrointestinal complications. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Arms Assigned Interventions
1: Experimental
HZT-501: Ibuprofen 800mg/Famotidine 26.6mg
Drug: Ibuprofen/famotidine
HZT-501: Ibuprofen 800mg/famotidine 26.6mg orally 3 times daily for 24 weeks
2: Active Comparator
Ibuprofen 800mg
Drug: Ibuprofen
Ibuprofen 800mg orally 3 times daily for 24 weeks

Detailed Description:

HZT-501 is a combination product including ibuprofen and the acid reducing agent famotidine. The study is designed to determine whether the combination product reduces the rate of ulcer development in subjects who require long-term daily use of ibuprofen.

Subjects will be assigned randomly, in approximately a 2:1 ratio, to treatment with either HZT-501 (ibuprofen 800 mg/famotidine 26.6 mg) or ibuprofen (800 mg) three times daily for a 24 week treatment period or until they develop either an endoscopically-diagnosed upper gastrointestinal ulcer and/or prohibitive toxicity. Subjects will visit the study center for Screening and at Weeks 4, 8, 16, and 24. Physical exams will be performed, and clinical laboratory measurements made, at selected times during the study. Endoscopic exams will be performed during Screening and at Weeks 8, 16, and 24. Subjects will be contacted four weeks following study completion.
