Primary Outcome Measures
NameTimeMethod
Number of Subjects With Clinically Significant Upper and/or Lower Gastrointestinal Events (CSULGIEs)6 month treatment duration

CSULGIE=any of the following: gastroduodenal (GD) hemorrhage; gastric outlet obstruction; GD, small or large bowel perforation; small or large bowel hemorrhage; clinically significant anemia of defined GI origin; acute GI hemorrhage of unknown origin, including presumed small bowel hemorrhage; clinically significant anemia of presumed occult GI origin including possible small bowel blood loss. Subjects were assessed by an independent GI Events Adjudication Committee, who were blinded to study treatment assignments.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Hemoglobin at Month 6/ETMonth 6/ET
Number of Subjects Withdrawn Due to GI Adverse Events (AEs)6 month treatment duration

GI AEs were defined using MedDRA SOC "Gastrointestinal Disorders" but excluding the following HLGTs: Benign Neoplasms Gastrointestinal; Dental and Gingival Conditions; Oral Soft Tissue Conditions; Salivary Gland Conditions; and Tongue Conditions.

Change From Baseline in Ferretin to Month 6/ETMonth 6/ET
Change From Baseline in Hepatic Measures of GGT, AST or ALT to Month 6/ETMonth 6/ET
Change From Baseline in Iron Binding Capacity to Month 6/ETMonth 6/ET
Change From Baseline in C-Reactive Protein to Month 6/ETMonth 6/ET
Number of Subjects With SUs6 month treatment duration

Subjects with evaluation at an event visit and found to have an ulcer on endoscopy, but did not meet any criteria considered for the primary endpoint by the GI committee were designated as having an SU.

Number of Subjects With CSULGIEs by History of GD Ulceration6 month treatment duration

CSULGIE=any of the following: gastroduodenal (GD) hemorrhage; gastric outlet obstruction; GD, small or large bowel perforation; small or large bowel hemorrhage; clinically significant anemia of defined GI origin; acute GI hemorrhage of unknown origin, including presumed small bowel hemorrhage; clinically significant anemia of presumed occult GI origin including possible small bowel blood loss. Subjects were assessed by an independent GI Events Adjudication Committee, who were blinded to study treatment assignments.

Number of Subjects With a Clinically Significant Decrease From Baseline in Hematocrit and/or Hemoglobin6 month treatment duration

A clinically significant decrease from baseline was defined as a fall in hematocrit \> = 10 percentage points and/or hemoglobin \> = 2 g/dL.

Number of Subjects With CSULGIES or Symptomatic Ulcers (SUs)6 month treatment duration

CSULGIE=any of the following: GD hemorrhage; gastric outlet obstruction; GD, small or large bowel perforation; small or large bowel hemorrhage; clinically significant anemia of defined GI origin; acute GI hemorrhage of unknown origin, including presumed small bowel hemorrhage; clinically significant anemia of presumed occult GI origin including possible small bowel blood loss. Subjects with evaluation at an event visit and found to have an ulcer on endoscopy, but did not meet any criteria considered for the primary endpoint by the GI committee were designated as having an SU.

Change From Baseline in Patient's Global Arthritis Assessment at Month 6/Early Termination (ET)Month 6/Early Termination (ET)

Subjects rated response to question: "Considering all the ways the osteoarthritis or rheumatoid arthritis affects you, how are you doing today?" using a 1 to 5 grading scale where 1=very good and 5=very poor.

Change From Baseline in Hematocrit at Month 6/ETMonth 6/ET
Number of Subjects With Moderate to Severe Abdominal Symptoms6 month treatment duration

Abdominal symptoms were defined by the Medical Dictionary for Regulatory Activities MedDRA System Organ Class (SOC) 'Gastrointestinal Disorders' and keeping high level group term (HLGT) equal to "Gastrointestinal Signs and Symptoms".

Number of Subjects With Hepatic AEs in Gamma Glutamyl-Transferase (GGT), Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) of 3 Times the Upper Limit of Normal (ULN)6 month treatment duration

GGT ULN was 49 international units (IU)/liter (L) for females and 61 IU/L for males, AST ULN was 37 IU/L for females and 39 IU/L for males, and ALT ULN was 43 IU/L for females and 45 IU/L for males.
