This clinical trial aims to clarify the effect of UltraHA® on knee joint conditions.

Study Overview

Status

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

In this study, the investigators will evaluate the knee condition before and after the intervention. The groups to be compared are two different doses of UltraHA® and a placebo.

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.

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
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at Week 12
Time Frame: Week 12
The WOMAC contains 24 questions, including pain for 5 questions, stiffness for 2 questions, and physical function for 17 questions, answered on a range of 0 (mildest) to 4 (most severe). The sum of responses is evaluated as the WOMAC scores.
Week 12

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
Each WOMAC subscale score at Week 12
Time Frame: Week 12
The WOMAC contains 24 questions, including pain for 5 questions, stiffness for 2 questions, and physical function for 17 questions, answered on a range of 0 (mildest) to 4 (most severe). The sum of each subscale response is evaluated as the WOMAC subscale score.
Week 12
Subjective symptoms at Week 12
Time Frame: Week 12
Assess knee pain, stiffness, discomfort, and health using visual analogue scale. There is a 100 mm straight line with the best and worst degree of sensation indicated at both ends, and the current degree of sensation is marked on the line with the best imaginable state being 0 and the worst state being 100.
Week 12
