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