Study Details

Study Description

Brief Summary

Knee osteoarthritis (KO) is a common arthropathy and a leading cause of disability in elderly adults. Schizandra chinensis(Omija) has been known to have five predominant tastes: salty, sweet, sour, astringent, and bitter. It has also been shown to have various effects on the anti-inflammatory, cardiovascular system, gastrointestinal system, central nervous system, endocrine system, and stress protect. Therefore, this study is designed to evaluate the efficacy and safety on KO of Omija extract.

Condition or Disease Intervention/Treatment Phase
  • Dietary Supplement: Omija extract.
  • Dietary Supplement: Placebo
Phase 2/Phase 3

Detailed Description

In the present study, the investigators will assess the efficacy and safety of the formulation of Omija extract(1,200 mg administered twice a day) on the symptoms of knee osteoarthritis (KO) during a 12-week treatment course. In a randomized, double-blind placebo-controlled trial, subjects will be randomly assign to receive oral omija treatment group(n=30) or placebo group(n=30). The primary efficacy outcome measure will be score change in the WOMAC(Western Ontario and McMaster University Osteoarthritis Index) after 12-weeks. Secondary parameters will be included the Lysholm index score, hs-CRP, osteocalcin(OSC), and deoxypyridinoline(DPYR).

Outcome Measures

Primary Outcome Measures

  1. Changes in WOMAC (Western Ontario and McMaster University Osteoarthritis Index) Totol Score [12 weeks]

    WOMAC(Western Ontario and McMaster University Osteoarthritis Index) total score (score 0-96) was measured in study visit 1(0 week) and visit 3(12 week). The original index consists of 24 Questions. Individual question response is assigned a score of between 0 (none) to 4 (extreme) and summed to form a score ranging from 0 (best) to 96 (worst).

Secondary Outcome Measures

  1. Changes in Lysholm Index Score [12 weeks]

    Lysholm index score total score (score 0-100) was measured in study visit 1(0 week) and visit 3(12 week). The original index consists of 9 Questions(Limp, Assive devices, Up stair, Giving way, Sauat, Sit down&up, Cripitation, Swelling, Pain). Lysholm index score total score summed to form a score ranging from 0 (worst) to 100 (best).

  2. Changes in Hs-CRP(High Sensitivity C-reactive Protein) [12 weeks]

    hs-CRP(high sensitivity C-reactive protein) was measured in study visit 1(0 week) and visit 3(12 week).

  3. Changes in OSC(Osteocalcin) [12 weeks]

    OSC(Osteocalcin) was measured in study visit 1(0 week) and visit 3(12 week).

  4. Changes in DPD(Deoxypyridinoline) [12 weeks]

    DPD(Deoxypyridinoline) was measured in study visit 1(0 week) and visit 3(12 week).
