Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The knee osteoarthritis is a frequent degenerative condition that mainly affects subjects over 60, population often weakened by numerous comorbidities and concomitant treatments, justifying the development of new therapies.

The viscosupplementation is a symptomatic treatment for knee osteoarthritis ; the objective of this intra-articular injection of hyaluronic acid is to reduce knee pain and improve mobility. In practice, there are two protocols to administer viscosupplementation : in a single injection or in three injections performed weekly.

The present clinical investigation has the objective to evaluate the safety and efficacy of use of Pandora, a hyaluronic acid associated with tranexamic acid, in a single injection (HO-1) or in three injections performed weekly (HS-3), compared to a referred and commercialized medical device.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This clinical investigation is a prospective, multicenter, randomized, parallel groups study of a class III Medical Device.

This study is designed to compare the safety of use and the efficacy of Pandora in its two forms : in a single injection (HO-1) or in three injections (HS-3) to a single intra-articular injection of 2.5 ml (SINOVIAL®ONE)

A descriptive analysis will be carried out to characterize the demographic data, the history of the disease and its treatments, the clinical and radiological data of the patients at inclusion.

The efficacy of Pandora will be demonstrated by describing the variation of WOMAC A1 score "walking pain" of target knee in repeated measures.

In total, 252 participants will be enrolled across 40 study centers in France and Monaco.

The total duration of subjects' participation is 12 months ; overall study duration including the enrollment period is expected to take approximately 24 months.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Prospective, multicenter, controlled, single blind, randomized in parallel groups Clinical Investigation.

Subjects will receive one of three viscosupplementations depending on the randomization.

The study includes two periods :

* The first period (26 weeks) : prospective, multicenter, randomized in three parallel groups study, comparing the two forms of Pandora gel (HO-1 and HS-3) to SINOVIAL® ONE. The comparison between HO-1 and SINOVIAL® ONE is realized in single blind and the comparison between HS-3 and SINOVIAL® ONE is realized without masking.
* The second period (26 weeks) is an exploratory, prospective, multicenter phase comparing these same devices without masking.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patient aged between 35 and 85 years.
* Body mass index (BMI) \< 35 kg.m2.
* Medial or lateral femoro-tibial knee osteoarthritis, diagnosed according to the American College of Rheumatology criteria, radiological stage 2 and 3 according to the Kellgren-Lawrence criteria modified by Felson on an X-ray, of the knee in extension, less than 6 months old.
* Knee osteoarthritis responsible for walking pain in the target knee, assessed between 4 and 8 inclusive on an 11 points numerical scale (0 = none to 10 = extreme).
* Unilateral or bilateral knee osteoarthritis if the walking pain in the contralateral knee is \< 3 based on 11 points numerical scale (0-10).
* Ambulatory patient able to walk 50 meters without a cane, crutch or walker.
* Patient giving his informed consent.
* Patient agreeing to follow-up study visits.
* Patient affiliated to the health social security system or beneficiary of such plan.
* Patient requiring viscosupplementation according to the investigator.

Exclusion Criteria

* Patient presenting knee osteoarthritis without impingement joint space narrowing of the femoro-tibial compartment (modified Kellgren stage 0-1) or with complete impingement joint space narrowing on the knee weight-bearing radiograph in extension (modified Kellgren stage 4).
