Outcome Measures
Primary Outcomes (1)
Mean Change From Baseline to Week 8 in WOMAC Pain Scale, Bioequivalence of Test to Reference.
WOMAC = Western Ontario and McMaster Universities Arthritis Index. The higher number is more pain. Change from baseline to Week 8 as indicated in the title. Scale is 5 questions with a scale of 0-4, higher number is more pain. Therefore, if you have 5 questions and the max score for each is 4, the maximum number on the scale is 20 (5 questions x 4 units on the scale = 20).
8 weeks
Secondary Outcomes (4)
An Evaluation to Determine Superiority of Test and Reference Against Placebo in the Mean Change From Baseline to Week 8 in the Total WOMAC Pain Score.

- Radiograph of the target knee within the previous year with a Grade 1, 2 or 3 disease based upon the Kellgren-Lawrence disease severity scale.
- After a minimum of 7-day wash out of all pain medication has Baseline pain on movement score of ≥ 50mm on a 0-100-mm Visual Analogue Scale for the target knee.
- After a minimum of 7-day wash out of all pain medication has Baseline WOMAC Pain sub scale of ≥ 9 on a 5 question, 5 point (0 to 4) Likert scale for the target knee.
- Willing and able to use only acetaminophen as rescue medication.

Patients who have had high blood pressure measured at least 2 (two) years prior to screening visit and have had no disease activity (i.e., no record of hypertension or anti-hypertensive treatment prescribed) for at least 2 (two) years prior to screening visit may enter into the study.
