  • Contraindications to 4% GAG: hypersensitivity to the product components;
  • Infections or skin diseases in the area of the injection site;
  • Change in the dosage of ongoing non-pharmacologic therapy for the lower extremities (including physical therapy) initiated in the month before first injection;
  • Anticoagulant (coumarinic compound) and heparin. Related to associated diseases
  • Severe diseases (e.g., liver or renal failure, lung/heart disease, tumour, HIV);
  • Severe alteration of mobility interfering with the functional evaluation;
  • High risk of haemorrhage;
  • Patient with known allergy to paracetamol;
  • Anticipated need for any surgical or other invasive procedure during the trial including prosthesis in the target knee.

Related to study subjects

• Participation to a therapeutic clinical trial in the last 3 months before first injection;
• Pregnancy, breastfeeding, planned conception and premenopausal women without contraception, tubal ligation or hysterectomy

Intervention / Treatment

Other: Hyaluronic Acid Combined With Chondroitin Sulfate; The treatment consists of 3 intra articular injections of Hyaluronic Acid With Chondroitin Sulfate administered one per week for 3 consecutive weeks: the 1st at Visit 1 (Week 0), the 2nd at Visit 2 (Week 1) and the 3rd at Visit 3 (Week 2)

Device: Hyaluronic Acid Combined With Chondroitin Sulfate; 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

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in pain score measured by Visual Analogue Scale (VAS)	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	at week 6, 14 and 26

Secondary Outcome Measures

Change from baseline up to 26 weeks after first treatment on knee functional disability on Clinical Observer Global Assessment (COGA)	Change from baseline up to 26 weeks after first treatment in COGA of knee functional disability, assessed by VAS (0-100)	at weeks 6, 14 and 26
Number of patients Responder to treatment	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.	Weeks 6, 14 and 26
Change from baseline in Synovitis at 6 weeks	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	at week 6
Change from baseline in Synovial hypertrophy at 6 weeks	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	at week 6
Change from baseline in knee Effusion at 6 weeks	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	at week 6
Change from baseline in popliteal cyst at 6 weeks	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	at week 6
Change in Synovial Power Doppler signal 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	at week 6
Safety of the treatment. Number of patient with treatment related adverse events	Safety evaluation by tracking the number of patient withdrawals and their adverse events correlated to treatment at each visit	through study completion
