Effect of Cis-9-cetylmyristoleate in Sub-healthy Subjects Presenting With Knee Joint Pain

June 10, 2016 updated by: Jeeyoun Moon, Seoul National University

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.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Active Comparator: 100% of JOINTRUS®
After randomization, 100% dose of JOINTRUS® is taken per day for 3 months in 7 sub-healthy persons >18 years of age and knee joint pain with a 0-10 numerical rating scale (NRS) pain score ≤ 4. This study included a 7-day baseline screening period (Visit 1) and was followed by randomization (Visit 2), a 12-week ingestion period with clinic visits at week 4 (Visit 3), 8 (Visit 4), and 12 (Visit 5) after starting ingestion, and a 4-week post-ingestion safety follow-up. The pain intensity, functional disability state and change in the general status were assessed for a 12-week ingestion period.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
CHANGE of Pain
Time Frame: change from baseline at 3 months
using the NRS score, composed of an 11-point scale from 0 (no pain) to 10 (the worst pain possible)
change from baseline at 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
difference in NRS pain score from baseline within groups
Time Frame: at 1-month follow-up, at 2-month follow-up, and at 3-month follow-up
at 1-month follow-up, at 2-month follow-up, and at 3-month follow-up
change of the WOMAC score
Time Frame: change from baseline at 3 months
using the Korean version of WOMAC
change from baseline at 3 months
Global Impression of Change
Time Frame: at 3-month follow-up
a scale ranging from 1 (very much improved) to 7 (very much worse).

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
