About this study

Official title: Efficacy and Safety of Omija Extract on Gonarthritis

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.

Read the 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).

What is being measured

The primary outcome is the main question the study is designed to answer.

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

    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).

    Measured: 12 weeks

Secondary outcomes (4)
  1. Changes in Lysholm Index Score

    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).

    Measured: 12 weeks

  2. Changes in Hs-CRP(High Sensitivity C-reactive Protein)

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

    Measured: 12 weeks

  3. Changes in OSC(Osteocalcin)

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

    Measured: 12 weeks

  4. Changes in DPD(Deoxypyridinoline)

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

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Omija extract. in people with Mild Knee Osteoarthritis, run by Chonbuk National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Feb 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in WOMAC (Western Ontario and McMaster University Osteoarthritis Index) Totol Score (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2013.
