  Purpose
Matrix metalloproteinases (MMPs) have been implicated in the cartilage degradation. PG-530742 inhibits some MMPs, potentially limiting cartilage degradation and disease progression. This study will test the efficacy and safety of PG-530742 in the treatment of mild to moderate knee osteoarthritis.

Primary Outcome Measures:
  • Change in Minimum Joint Space Width in the Medial Compartment of the Tibiofemoral Joint of the Signal Knee After 1 Year of Treatment [ Time Frame: baseline and 12 months ]
    The structural primary efficacy endpoint is the 1-year change from baseline in minimum joint space width (JSW) in the medial compartment of the tibiofemoral joint of the signal knee, as measured by microfocal knee radiographs obtained in the semi-flexed position.

  • Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Total Score at 1 Year [ Time Frame: baseline and 12 months ]
    The symptomatic primary efficacy endpoint is the change in total WOMAC scores after 1 year of treatment. The WOMAC consists of 24 items divided into 3 subscales: Pain (5 items), Stiffness (2 items), Physical Function (17 items). The WOMAC uses descriptors for all items: none, mild moderate, severe, and extreme (corresponding to an ordinal scale of 0-4.) Scores are summed for items in each subscale, with possible ranges as follows: pain=0-20, stiffness=0-8, physical function=0-68. The total WOMAC score is created by summing the items for all three subscales (min=0, max=96)

Detailed Description:
Matrix metalloproteinases have been implicated in the cartilage degradation that occurs in osteoarthritis. PG-530742 inhibits some of these matrix metalloproteinases, thus potentially limiting cartilage degradation and disease progression. This study will test the efficacy and safety of PG-530742 in the treatment of mild to moderate knee osteoarthritis.
