Outcome Measures

Primary Outcomes (3)

  • Change in Western Ontario and McMaster Universities (WOMAC) Pain Questionnaire Subscore From Baseline

    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).

    Baseline and 12 weeks

  • Change in Western Ontario and McMaster Universities (WOMAC) Function Questionnaire Subscore From Baseline

    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).

    12 weeks

  • Change in Patient Global Assessment (PGA) Subscore From Baseline

    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.

    12 weeks

Secondary Outcomes (9)

  • American Pain Society Patient Outcome Questionnaire (APS-POQ)Total Interference Caused by Pain.

    Baseline and Day 7

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or non-pregnant female subjects50 years of age and older with a 6-month history of OA of the knee
  • Female subjects were eligible for participation in the study if they were of non-childbearing potential (i.e., physiologically incapable of becoming pregnant); or of childbearing potential, had a negative pregnancy test at Screening, and using adequate contraceptive methods.
  • Subjects were required to have been on a stable dose of NSAIDs, COX-2 inhibitors or other oral analgesic therapy for at least 6 weeks and required to continue treatment for 12 weeks. Current oral analgesic therapy was withdrawn at Screening.
  • Each subject was required to be able to understand and comply with study procedures required of a subject and was able and willing to provide written informed consent prior to any study procedures being performed.
  • Subjects were required to agree to keep physical activity at a stable level throughout the study.
  • Subjects were required to have symptomatic OA of the knee meeting American College of Rheumatology (ACR) criteria for clinical diagnosis of OA.
  • Subjects were required to have an ACR functional class rating of I, II or III. In addition, subjects meet the requirements for OA flare at the Baseline/ Randomization Visit.

You may not qualify if:

  • Subjects with rheumatoid arthritis or gout/pseudo-gout
  • Subjects with fibromyalgia syndrome
  • Acute joint trauma at the index joint within the 3 months prior to screen with active symptoms
  • Previous (in the past 12 months) or anticipated need for surgical or invasive procedure performed on the index joint during the study
  • Subject was currently taking or anticipated to take Coumadin®, warfarin, or lithium
  • History of hypersensitivity to esomeprazole or to another PPI
  • History of allergic reaction or intolerance to any NSAID (including aspirin) and/or subject had a history of NSAID-induced symptoms of asthma, rhinitis, and/or nasal polyps
  • History of allergic reactions to sulfonamides
  • Subjects with intra-articular or intramuscular corticosteroids or intra-articular hyaluronic acid injections within 8 weeks prior to randomization
  • Participation in any study of an investigational treatment in the 4 weeks before Screening
  • Presence of uncontrolled acute or chronic medical illness, e.g. morbid obesity, GI disorder, diabetes, active GI disease, chronic or acute renal or hepatic disorder, depression and/or infection, etc, that would endanger a subject if the subject were to participate in the study
  • GI disorder (e.g., severe erosive esophagitis, Zollinger Ellison syndrome) or surgery leading to impaired drug absorption
  • Peptic ulcer disease within 6 months prior to Screening
  • Evidence of uncontrolled, or unstable cardio- or cerebrovascular disorder, which in the investigator's opinion would have endangered a subject if the subject were to participate in the study
  • Schizophrenia or bipolar disorder
  • +10 more criteria
