Study Description
Brief Summary:
The purpose of this study is to evaluate efficacy and safety of SI000413 in patients with knee osteoarthritis by orally administration and to determine optimal dose.

Condition or disease Intervention/treatment Phase
Osteoarthritis, Knee Drug: SI000413 Drug: microcrystalline cellulose Phase 2

Detailed Description:

This is a dose-response, double blind , placebo-controlled study. All patients are required to have 2 weeks washout period from prior medication. Subjects will discontinue current medications 2 weeks prior to randomization. Among those who meet the inclusion criteria, only subjects recording visual analogue scale(VAS) of higher than 40mm(VAS range from 0mm(no pain) to 100mm(unbearable pain)) are enrolled in this study.

Subjects meeting screening criteria will be randomized to receive 8 weeks dosing of an active dose of SI000413 or placebo.

Outcome Measures

Primary Outcome Measures :
  1. K-WOMAC [ Time Frame: Visit 6(8 week), baseline ]
    The primary endpoint will be the change in the sum of the K-WOMAC OA index at Visit 6(8 weeks) vs. baseline(Visit 2, 0 week).

Secondary Outcome Measures :
  1. knee pain intensity assessment [ Time Frame: baseline, Visit 4(4 week), Visit 6(8 week) ]
    The change from baseline to each day(4 week and 8 week). Subjects assess knee pain intensity by using 100mm VAS at each time.

  2. Global assessment(regarding to disease activity) [ Time Frame: Visit 4(4 week), Visit 6(8 week) ]
    The change from Visit 4 to Visit 6 using 100mm VAS. Each patient and investigator assess by using 100mm VAS.

  3. K-WOMAC each domain assessment [ Time Frame: baseline, Visit 6(8 week) ]

    The change from Visit 6(8 weeks) vs. baseline(Visit 2, 0 week) in the K-WOMAC each domain score.

    * K-WOMAC 3 domains: pain domain, stiffness domain, physical function domain

  4. ESR & hs-CRP [ Time Frame: baseline, Visit 4(4 week), Visit 6(8 week) ]
    The change from baseline to each day(Visit 4, Visit 6) using laboratory test.
