Combination of PRP and XLHA Prepared With RegenMatrix Medical Device To Treat Moderate to Severe Knee Osteoarthritis
Study Details
Study Description
Brief Summary
In this clinical trial the investigator assess the safety and efficacy of a single injection of a combination of cross-linked hyaluronic acid (HA) with autologous platelet-rich plasma (PRP) obtained with the RegenMatrix medical device to improve symptoms of moderate to severe knee osteoarthitis (grade III-IV Kellgren-Lawrence).

Detailed Description
In this multicenter, randomized, double-blind, three-arm study, the investigator propose to evaluate the safety and efficacy at Day0, Month1, Month3 and Month6 of a single intra-articular injection of a combination RM-PRP-XLHA (experimental treatment: combination of cross-linked HA and PRP obtained with the RegenMatrix medical device) against Hylan G-F 20 (reference treatment) and placebo for the treatment of moderate to severe knee osteoarthritis.
The symptomatic benefit will be evaluated in terms of pain reduction and improvement of patient's quality of life. The functional benefit of the treatment will also be evaluated, on a reduced number of participants, by a gait analysis, performed only in the coordinating centre.
The medical device RegenMatrix is an adaptation of the medical device Cellular Matrix (certified since 2013,CE2797). It differs from the latter only for by presence of cross-linked HA instead of linear HA, and is therefore particularly suitable for the treatment of moderate to severe knee osteoarthritis.

Outcome Measures
Primary Outcome Measures
- Variation in the osteoarthritis related pain [6 months (Day 0 - Month 6)]
It will be assessed by the mean difference in the WOMAC A score on a 100-mm VAS overtime
Secondary Outcome Measures
- Variation in the overall osteoarthritis related pain [M1 and M3 (Day 0-Month 1; Day 0 - Month 3)]
It will be assessed by the mean difference in the WOMAC A score on a 100-mm VAS overtime
- Variation of joint stiffness after the first awakening and later in the day [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
It will be assessed by the mean difference in the WOMAC B score overtime
- Variation of joint function during daily activity [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
It will be assessed by the mean difference in the WOMAC C score overtime
- Variation in the osteoarthritis related symptoms [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
It will be assessed by the mean difference in the total WOMAC score Month 1, Month 3 and M6 (D0-M1; D0-M3; D0-M6)
- Variation of patient's quality of life [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
It will be assessed by the SF-12 questionnaire
- Pain, function, patient's general assessment [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
It will be assessed by the% of OMERACT-OARSI responders
- Assessment of the minimal meaningful change according to the patient's perception [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
The Minimal Clinically Important Improvement (MCII) will be assessed on the basis of the answers to the WOMAC questionnaire.
- Assessment of the highest level of symptom beyond which patients consider themselves well. [Month 1, Month 3 and Month 6 (D0-Month 1; Day 0-Month 3; Day 0-Month 6)]
The Patient Acceptable Symptom State (PASS) will be assessed on the basis of the answers to the WOMAC questionnaire.
- Rescue medication [Month 1, Month 3 and Month 6 (Day 0-Month 1; Day 0-Month 3; Day 0-Month 6)]
Consumption of level 1 and 2 painkillers, NSAIDs and corticosteroids
