About this study

Official title: The Minimal Effective Dose of Cis-9-cetylmyristoleate (CMO) in Persons Presenting With Knee Joint Pain

Cis-9-cetylmyristoleate (CMO) is a naturally occurring fatty acid complex (FAC). Nutraceuticals containing CMO are used to improve knee pain despite the lack of placebo-controlled studies in humans. The aim of the double-blind controlled clinical trial is to explore the minimal effective dose of CMO for relieving knee joint pain.

Read the detailed description

Methods: Twenty-eight subjects, who are clinically or radiologically diagnosed as having mild degree arthritic knee joint pain, are randomized into 3 groups; Groups A, B, C that contained 100%, 80%, and 62.4% of fatty acid component with 12.5% of Cis-9-cetylmyristoleate (CMO), and control Group D (starch 100%). The pain intensity, functional disability state and change in the general status were assessed for a 12-week ingestion period.

Being tested
JOINTRUS®, 80% dose of JOINTRUS®, 62.4% dose of JOINTRUS®, Starch 100%

What is being measured

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

  1. CHANGE of Pain

    using the NRS score, composed of an 11-point scale from 0 (no pain) to 10 (the worst pain possible)

    Measured: change from baseline at 3 months

Secondary outcomes (3)
  1. difference in NRS pain score from baseline within groups

    Measured: at 1-month follow-up, at 2-month follow-up, and at 3-month follow-up

  2. change of the WOMAC score

    using the Korean version of WOMAC

    Measured: change from baseline at 3 months

  3. Global Impression of Change

    a scale ranging from 1 (very much improved) to 7 (very much worse).

    Measured: at 3-month follow-up

Questions about this trial

What is this clinical trial studying?

A study testing JOINTRUS®, 80% dose of JOINTRUS® and 62.4% dose of JOINTRUS® in people with Knee Pain Intermittent, run by Seoul National University.

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 1 inclusion and 12 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 15 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

CHANGE of Pain (time frame: change from baseline at 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02800759, which also lists 9 linked publications.

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 15 Jun 2016.
