Brief Summary:
The purpose of this clinical trial is to evaluate the efficacy and safety of Cortex Eucommiae (CE: Eucommia ulmoides Oliver extract) in subjects with mild osteoarthritis (OA).

Condition or disease Intervention/treatment Phase
Osteoarthritis Dietary Supplement: CE Dietary Supplement: Placebo Not Applicable

Detailed Description:
This is a 12-week, multi-center, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of Cortex Eucommiae (CE: Eucommia ulmoides Oliver extract) in subjects with mild OA. One hundred subjects with mild OA will be recruited and randomly divided into 2 groups, each group will receive Cortex Eucommiae (CE: Eucommia ulmoides Oliver extract) or placebo and will take CE or placebo for 12 weeks. Outcomes will be evaluated by self-administered questionnaires and lab test results. The hypothesis is that Cortex Eucommiae (CE: Eucommia ulmoides Oliver extract) which as a dietary supplementation may slow down or reverse OA.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. VAS (Visual Analogue Scale) [ Time Frame: Change of the week 6, 12 from baseline ]
    VAS to measure changes in joint pain on 6, 12 weeks after administration in comparison with baseline

  2. K-WOMAC (Korean-Western Ontario and McMaster Universities) [ Time Frame: Change of the week 6, 12 from baseline ]
    K-WOMAC to measure changes in joint pain and function on 6, 12 weeks after administration in comparison with baseline

  3. KSF-36 (Korean-Short Form Health Survey 36) [ Time Frame: Change of the week 6, 12 from baseline ]
    KSF-36 to measure changes in physical and mental function on 6, 12 weeks after administration in comparison with baseline


Secondary Outcome Measures :
  1. Subject's global impression of change scale [ Time Frame: 6 weeks, 12 weeks ]

    The change in activity limitations, symptoms, emotions and overall quality of life, related to painful condition that is assessed by subject

    Level of Quality

    • Excellent: substantial overall improvement of symptoms
    • Good: overall improvement of symptoms
    • Neutral: no change compared with before
    • Worse: overall deterioration of symptoms
    • Very much worse: substantial overall deterioration of symptoms

  2. Investigator's global impression of change scale [ Time Frame: 6 weeks, 12 weeks ]

    The change in activity limitations, symptoms, emotions and overall quality of life, related to painful condition that is assessed by investigator

    Level of Quality

    • Excellent: substantial overall improvement of symptoms
    • Good: overall improvement of symptoms
    • Neutral: no change compared with before
    • Worse: overall deterioration of symptoms
    • Very much worse: substantial overall deterioration of symptoms

  3. ESR (Erythrocyte sedimentation rate) [ Time Frame: Change of the week 12 from baseline ]
    ESR to measure changes in blood inflammatory marker on 12 weeks after administration in comparison with baseline

  4. CRP (C-reactive protein) [ Time Frame: Change of the week 12 from baseline ]
    CRP to measure changes in blood inflammatory marker on 12 weeks after administration in comparison with baseline
