Arm Intervention/treatment
Active Comparator: 1
SMC021 Oral Calcitonin

SMC021 Placebo
Drug: Oral Salmon Calcitonin (Placebo)

Primary Outcome Measures :
  1. Joint Space Width (JSW) in the Medial Tibia-femoral Knee Joint in the Signal Knee Measured by X-ray Change From Baseline Over 24 Months [ Time Frame: Change from baseline to 24 months ]
    The signal knee was chosen prior to randomization based on which knee met the inclusion and exclusion criteria. The JSW is the space measured in mm between the 2 bones in the knee joint and this is assessed by x-ray. The JSW decreases with disease progression. The lower limit for participation in the trial were 2 mm JSW. There were no upper limit as long as inclusion and exclusion criteria were met. The outcome was measured as a change in JSW from baseline to month 24.

  2. Pain Subscore Change From Baseline Over 24 Months as Assessed by Western Ontario and McMaster Universities Arthritis (WOMAC) Index [ Time Frame: Change from baseline to 24 months ]
    WOMAC is a self-administered set of standardized questionnaires to evaluate the condition of patients with osteoarthritis of the knee. The subject marks on a scale (1-100) the pain associated with performing each daily activity listed in the questionnaire. 0 is no pain (best), 100 is extreme pain (Worst). The total pain sub score for the questions are then calculated. Total possible minimum sub score is 0, maximum is 500. The final outcome is the absolute change from baseline to 24 months. If the outcome is less that 0 there is improvement (less pain).

Secondary Outcome Measures :
  1. • Bone & Cartilage Metabolism Biochemical Marker Change. • Questionnaires to Assess Function, Stiffness, Pain, Physical Activity, and Quality of Life • Knee Disease Progression Assessed by MRI [ Time Frame: From baseline to 24 months ]
