Conditions

Device: SYNVISC-ONE
Registration Number
NCT03203408
Lead Sponsor

Brief Summary

The main objective of the study was to demonstrate the non-inferiority of the efficacy of a single intra-articular injection of OSTENIL PLUS compared to that of a single intra-articular injection of the reference product SYNVISC-ONE in the treatment of symptomatic tibiofemoral osteoarthritis. The primary endpoint was the change in mean score on the WOMAC pain scales from D0 to D180.

Detailed Description

After a period of washout-out for NSAIDs, the patients received a single intra-articular injection of OSTENIL PLUS or of SYNVISC-ONE in the most painful knee. The study involved a preselection visit at D-7 and five further visits: at D0 (baseline, evaluation before intra-articular injection), at D2 ± 2 days (injection), at D30 ± 15 days, at D90 ± 15 days and C5 at D180 ± 15 days.

To enrol the patients as quickly as possible, 129 sites, i.e. general medical or rheumatology practices, were open. After verifying the inclusion and exclusion criteria, the evaluating investigators assigned a randomisation number based on the chronological order of inclusion of patients at their site. The patient was then sent to the injecting investigator so that he/she could give the injection of the product corresponding to the randomisation number.

  • Bilateral symptomatic knee osteoarthritis of the same severity on both sides;
  • Post-traumatic secondary knee osteoarthritis;
  • Knee osteoarthritis of radiographic grade I, Ia or IV;
  • Exclusively patellofemoral osteoarthritis where the symptoms are principally of patellofemoral origin (Patellar syndrome);
  • Symptomatic homolateral coxarthrosis;
  • Varus or valgus deformation of the selected knee (deformation axis ≥15° in X-ray);

  • Femoral or sciatic nerve root pain of the lower limb to be tested;
  • Tendinopathy (e.g. hip periarthritis);
  • Treatment with intra-articular hyaluronic acid in the selected knee during the 6 months before inclusion;
  • Intra-articular injection of corticosteroids in the selected knee during the 2 months before inclusion;
  • Treatment with symptomatic slow-acting drugs for osteoarthritis and/or dietary supplements for osteoarthritis (chondroitin sulphate, diacerein, avocado and soybean unsaponifiables, oxaceprol, copper granions, glucosamine) which had been started less than 3 months previously or whose dose had been changed during the last 3 months before inclusion;
  • Total knee replacement of the selected knee;
  • Surgery of the other knee or of the hip or any other surgery scheduled during the period of the study;
  • History of any surgical intervention, arthroscopy, osteotomy, etc. in the year before inclusion;
  • Obesity: body mass index ≥30 kg/m2;
  • History of autoimmune disease;

  • Wound or skin condition of the selected knee;
  • Anticoagulant treatment with heparin or warfarin (platelet antiaggregants such as ASPIRIN ≤325 mg/d, ticlopidine or clopidogrel were allowed);
  • Known hypersensitivity to hyaluronic acid and/or to avian proteins and/or paracetamol;
  • Known hypersensitivity to mannitol;
  • Participation in a clinical research study within the previous 3 months;
