Current Primary Outcome Measures
  • Change in Western Ontario and McMaster Universities (WOMAC) Pain Questionnaire Subscore From Baseline [Time Frame: Baseline and 12 weeks] [Designated as safety issue: No]Western Ontario and McMaster Universities (WOMAC) pain questionnaire has 5 questions on pain all use visual analog scale (VAS) of 100 mm, with 0 mm being "no pain" and 100 mm being "extreme pain". The outcome measures a change in WOMAC pain at 12 weeks from baseline (in mm). WOMAC is a self-administered, patient-reported health status questionnaire designed to capture elements of pain, stiffness and physical disability in patients with OA of the knee and/or hip joints. It consists of 24 questions (5 questions about pain, 2 on stiffness and 17 about physical function).
  • Change in Western Ontario and McMaster Universities (WOMAC) Function Questionnaire Subscore From Baseline [Time Frame: 12 weeks] [Designated as safety issue: No]WOMAC function questionnaire (VAS). The 17 questions about function all use visual analog scale (VAS) of 100 mm; 0 mm being "no pain" and 100 mm being "extreme pain". The outcome measures a change in WOMAC pain from baseline (in mm).
    The Western Ontario and McMaster Universities (WOMAC) is a self-administered, patient-reported health status questionnaire that is designed to capture elements of pain, stiffness and physical disability in patients with OA of the knee and/or hip joints. The index consists of 24 questions (5 questions about pain, 2 on stiffness and 17 about physical function).
  • Change in Patient Global Assessment (PGA) Subscore From Baseline [Time Frame: 12 weeks] [Designated as safety issue: No]PGA questionnaire. The patient global assessment (PGA) question asks about how the subject is doing considering his/her arthritis and is measured by a visual analog scale (VAS); 0 mm (very poor) 100 mm (excellent). The outcome measures a change from baseline PGA in mm.
Current Secondary Outcome Measures
  • American Pain Society Patient Outcome Questionnaire (APS-POQ)Total Interference Caused by Pain. [Time Frame: Baseline and Day 7] [Designated as safety issue: No]Mean change from Baseline scores calculated for each subject through Day 7. Scale 0 through 70, where 0=no pain interference and 70=complete interference.
  • Change in Western Ontario and McMaster Universities (WOMAC) Pain Questionnaire Subscore From Baseline [Time Frame: Week 6] [Designated as safety issue: No]Western Ontario and McMaster Universities (WOMAC) pain questionnaire has 5 questions on pain all use visual analog scale (VAS) of 100 mm, with 0 mm being "no pain" and 100 mm being "extreme pain". The outcome measures a change in WOMAC pain at 6 weeks from baseline (in mm). WOMAC is a self-administered, patient-reported health status questionnaire designed to capture elements of pain, stiffness and physical disability in patients with OA of the knee and/or hip joints. It consists of 24 questions (5 questions about pain, 2 on stiffness and 17 about physical function).

The 17 questions about function all use visual analog scale (VAS) of 100 mm; 0 mm being "no pain" and 100 mm being "extreme pain". The outcome measures a change in WOMAC pain from baseline (in mm).

The outcome measures a change from baseline PGA in mm.
  • Antacid Tablet Use [Time Frame: 12 weeks] [Designated as safety issue: No]Tablet pill count
  • Modified Severity of Dyspepsia Assessment (mSODA) [Time Frame: Baseline to 12 weeks] [Designated as safety issue: No]Change from Baseline in the Modified Severity of Dyspepsia Assessment (mSODA) average daily pain intensity converted total score at Week 12. The mSODA instruments consists of 6 questions about abdominal discomfort during the past 24 hours, with a converted score of 2 through 47. Lower score equals less pain.
  • Percent of Days With no Heartburn (Heartburn Resolution) [Time Frame: 12 weeks] [Designated as safety issue: No]During 12 weeks, daily heartburn question with ratings none, mild, moderate, or severe. Percent of days with Heartburn resolution (heartburn is none).
  • Number of Participants Reporting Pre-specified Non-steroidal Antiinflammatory Drug-associated Upper Gastrointestinal (UGI) Symptoms [Time Frame: daily during 12 weeks] [Designated as safety issue: No]Number of participants reporting pre-specified non-steroidal antiinflammatory drug-associated (NSAID) upper gastrointestinal (UGI) symptoms. Pre-specified NSAID-associated UGI symptoms include adverse events such as dyspepsia, abdominal pain or discomfort, nausea, vomiting.
  • The Number of Subjects Who Discontinued From the Study Due to Any Pre-specified Non-steroidal Antiinflammatory Drug-associated Upper Gastrointestinal Adverse Event [Time Frame: daily during 12 weeks] [Designated as safety issue: Yes]The number of subjects who discontinued from the study due to any pre-specified non-steroidal antiinflammatory drug (NSAID)-associated upper gastrointestinal (UGI) adverse event (as classified by MedDRA). Pre-specified NSAID-associated UGI symptoms include adverse events such as dyspepsia, abdominal pain or discomfort, nausea, vomiting.
