Osteo Arthritis Knee
Conditions
Keywords
Hyaluronic Acid, Chondroitin sulfate
Brief summary
This is a multicentre, prospective, sponsor initiated clinical investigation that aims to evaluate safety and efficacy of Hyaluronic Acid Combined With Chondroitin Sulfate in symptomatic patients with OA of the knee.
Interventions
Subjects' participation in the study will last 26 weeks. The study includes 7 visits that consist of a Screening visit, three treatment visits and three follow-up visits. Eligible subjects will undergo a Baseline visit (V1 at week 0) during which, after the confirmation of eligibility, assessments and ultrasound evaluation, the study subjects will be treated with the 1st injection of 2%Hyaluronic Acid and 2% chondroitin sulfate Subsequent treatments will be administered at weekly intervals during Visit 2 (V2 at week 1) and Visit 3 (Visit 3 at week 2) after the effectiveness assessments. Study subjects will return for Follow-up visits 1 month (Visit 4 at week 6), 3 months (Visit 5 at week 14) and 6 months (Visit 6 at week 26) after the last injection

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain score measured by Visual Analogue Scale (VAS) | at week 6, 14 and 26 | Change in pain perception from baseline in patient with knee osteoarthritis after three intra-articular 2% Chondroitin Sulfate + 2% hyaluronic Acid injections assessed by Visual Analogue Scale (VAS) (From 0 to 100) at weeks 6, 14 and 26 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in knee pain and function up to 26 weeks | at weeks 6, 14 and 26 | Change from baseline provided by the intra-articular 2% Chondroitin Sulfate + 2% Hyaluronic Acid injections measured by Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index (0-100 mm) for knee at weeks 6, 14 and 26 |
| Change from baseline up to 26 weeks after first treatment on knee functional disability on Clinical Observer Global Assessment (COGA) | at weeks 6, 14 and 26 | Change from baseline up to 26 weeks after first treatment in COGA of knee functional disability, assessed by VAS (0-100) |
| Number of patients Responder to treatment | Weeks 6, 14 and 26 | Number of patients with clinical response to treatment using the OMERACT-OARSI set of criteria: high improvement in pain or function ≥ 50% or improvement in at least 2 of the 3 of the following criteria: high improvement in pain or function ≥ 50% or improvement in at least 2 of the 3 following: * pain ≥ 20% and absolute change ≥10, * function ≥20% and absolute change ≥10, * PGA ≥ 20% and absolute change ≥10. |
| Change from baseline in Synovitis at 6 weeks | at week 6 | Change in Synovitis at week 6 vs week 0 assessed by ultrasound scored according to the scoring systems proposed by OMERACT US on knee OA. A global score for synovitis corresponds to the maximum score for synovitis obtained at the suprapatellar or parapatellar recesses. Synovitis (grades 0-3): Grade 0 = no synovitis, Grade 1= minimal distension, Grade 2= moderate distension or enlargement, Grade 3= severe distension or enlargement of the recess |
| Change in Patient's Global Assessment | at weeks 6, 14 and 26 | Change from baseline up to 26 weeks after first treatment in Patient's Global Assessment of knee functional disability, assessed by VAS (0-100) |
| Change from baseline in knee Effusion at 6 weeks | at week 6 | Change in Effusion at week 6 vs week 0 assessed by ultrasound scored according to the scoring systems proposed by OMERACT US on knee OA. Effusion (0-1) 0= absence, 1= presence |
| Change from baseline in popliteal cyst at 6 weeks | at week 6 | Change in Popliteal cyst at week 6 vs week 0 assessed by ultrasound scored according to the scoring systems proposed by OMERACT US on knee OA. Popliteal cyst (0-1) 0= absence, 1= presence |
| Change in Synovial Power Doppler signal at week 6 | at week 6 | Changein Synovial Power Doppler signal at week 6 vs week 0 assessed by ultrasound. Synovial Power Doppler signal (0-1) and (0-3) Grade 0 = no intra-articular colour signal Grade 1 = up to three signal colour signals or two single and one confluent colour signals representing only low flow |
| Safety of the treatment. Number of patient with treatment related adverse events | through study completion | Safety evaluation by tracking the number of patient withdrawals and their adverse events correlated to treatment at each visit |
| Change from baseline in Synovial hypertrophy at 6 weeks | at week 6 | Change in Synovial hypertrophy at week 6 vs week 0 assessed by ultrasound scored according to the scoring systems proposed by OMERACT US on knee OA. Synovial hypertrophy (0-1) where 0= absence, 1= presence |
