Comparing Efficacy and Safety of a Single Intraarticular Injection of a Novel Crosslinked Hyaluronic Acid (HYAJOINT Plus) With Synvisc-One for the Treatment of Knee Osteoarthritis: A Randomized-Controlled, Double-Blind Trial

Viscosupplementation has been widely used for the treatment of knee osteoarthritis (OA). There is no well controlled trial comparing one injection regimen of HA for the treatment of knee OA. The purpose of this study was to compare the efficacy and safety of one intraarticular injection of a novel crosslinked HA (HYAJOINT Plus) with Synvisc-One for the treatment of knee OA.

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 a prospective, randomized controlled, double-blind trial with 6-month follow up, patients with knee OA (Kellgren-Lawrence grade 2 or 3) were randomized to receive one intraarticular injection of 3 ml HYAJOINT Plus (microbial fermented HA, 20 mg/ml) (N=66) or 6 ml Synvisc-One (avian derived HA, 8 mg/ml) (N=66). The primary outcome was change in the visual analog scale (VAS) pain (0-100mm) over 6 months. Secondary outcomes included The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequesne index, Timed Up-and-Go test (TUG), single leg stance test (SLS), use of rescue analgesics and patient satisfaction.

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.

Ages Eligible for Study

36 years to 81 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

    • grade 2 or 3 knee OA according to the Kellgren-Lawrence grading system based on radiographs taken within the previous 6 months
    • Radiological evidence of bilateral knee OA was accepted if global pain VAS in the contralateral knee was less than 30 mm.

Exclusion Criteria:

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
VAS pain score
Time Frame: at 1, 3 and 6 months postinjection
the change from baseline in the VAS pain score over 6 months.
at 1, 3 and 6 months postinjection

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
WOMAC, Likert Scale
Time Frame: at 1, 3 and 6 months postinjection
a 24-item questionnaire with 3 subscales measuring pain, stiffness, and physical function. Total score is 96 and lower scores indicate better outcomes.
at 1, 3 and 6 months postinjection
Lequesne index
Time Frame: at 1, 3 and 6 months postinjection
Maximal score is 24 and higher scores represent worse function.
at 1, 3 and 6 months postinjection
Timed Up-and-Go test (TUG)
Time Frame: at 1, 3 and 6 months postinjection
a simple measurement of time in seconds for a person to rise from an armchair, walk 3 meters, turn around, walk back to the chair, and sit down
at 1, 3 and 6 months postinjection
Single-leg stance test (SLS)
Time Frame: at 1, 3 and 6 months postinjection
by raising one foot up without touching it to the supported lower extremity with target knee OA and maintain balance for as long as possible.
at 1, 3 and 6 months postinjection
satisfaction based on a 100 mm VAS
Time Frame: at 1, 3 and 6 months postinjection
Patients were asked to rate their treatment satisfaction compared to the preinjection condition, based on a 100 mm VAS
at 1, 3 and 6 months postinjection
The reported adverse events
Time Frame: at 1 week (safety records via phone call), 1, 3 and 6 months after the injection
based on adverse events reported by the patients during the study period and physical examination findings by the evaluator after injections and at each follow-up visit
at 1 week (safety records via phone call), 1, 3 and 6 months after the injection
