About

The objective of this study was to explore the efficacy, dose-response and safety of PG201 tablet in Korean patients with osteoarthritis.

Full description

In this study, the PG201 extract, the study drug, was administered twice daily after a meal to two investigational groups, the lower-dose group and the higher-dose group. The efficacy of each of dose group was compared to that of the control group to determine if there was a statistically significant difference between the investigational groups and the placebo group. In addition, the efficacy between the lower dose group and the high dose group was also compared to determine if there was a statistically significant difference.

  • Patients with symptomatic primary osteoarthritis of the knee at least in the last 3 months prior to screening.
  • Patients with severity of grade 2 or 3 according to Kellgren & Lawrence scale based on anteroposterior radiographic evidence of the tibiofemoral joints with osteoarthritis, and who are classified in functional class of I, II or III according to the American Rheumatism Association functional classification.
  • Patients who had a score of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale question 1 ≤80 mm at screening, a score of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale question 1 ≥50 mm at baseline. a decrease in the score of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale question 1 at least by 15mm from screening to baseline and a decrease in the patient self-assessed arthritis symptoms scores at least by one point from screening to baseline.

Exclusion criteria

  • Patients with a known hypersensitivity or intolerance to Nonsteroidal antiinflammatory drugs (NSAIDs), aspirin or Cyclooxygenase-2 inhibitor.
  • Patients with a clinical or biochemical abnormal finding (excluding any finding related to the investigating disease) at the screening visit, which in the investigator's opinion was considered to be clinically significant or might make safe participation in the study more difficult

Patients who have any two or more of bilirubin, Alanine aminotransferase or Aspartate aminotransferase level greater than the Upper Lange of normal will also be excluded.
