Outcomes

Primary Outcome Measures

Pain as assessed by Numerical Pain Rating Scale (NPRS)
To evaluate the impact of PG-OA-10CN and PG-OA-10TC on the subject's osteoarthritis of the knee pain as assessed by utilizing a Numeric Pain Rating Scale (NPRS). NPRS is from 0-10, where higher scores indicate worse pain and lower scores indicate less pain reported by the subject.
Pain as assessed by the Knee Injury and Osteoarthritis Outcome Score (KOOS)
To evaluate the impact of PG-OA-10CN and PG-OA-10TC on the subject's osteoarthritis of the knee pain as assessed by the Knee Injury and Osteoarthritis Outcome Score (KOOS). KOOS is scored from 0-100, where 0 represents extreme problems and 100 represents no problems, as reported by the subject.

Secondary Outcome Measures

Incidence of treatment-related adverse events as assessed by CTCAE v4.0.
To evaluate the safety of PG-OA-10CN and PG-OA-10TC for the treatment of pain associated with osteoarthritis of the knee compared to a placebo control assessed by Common Terminology Criteria For Adverse Events (CTCAE) v4.0.
