Brief Summary

This multicentre, prospective, randomized, double-blind, active-controlled, parallel group clinical investigation is aimed to assess the safety and the clinical performance over 6 months of a single intra-articular injection of PVA Hydrogel, novel polyvinyl alcohol preparation, as compared to hyalan G-F20, (Synvisc-One®) one of the most commonly used and best performing hyaluronic acid based products, in patients with symptomatic knee osteoarthitis (OA).

Detailed Description

To compare the effects of a single intra-articular injection of a novel polyvinyl alcohol preparation (PVA Hydrogel) and hylan G-F20 (Synvisc-One®) in patients with symptomatic knee OA.

Patients with knee OA (ACR clinical and radiological criteria) symptoms for ≥6 months, insufficient/failed response to analgesics, K&L stage II-III (x-Rays within past 12 months), a knee pain score of 4-9 (0-10 NRS) in the target knee and <3 in the contralateral knee, will be enrolled in a randomised, controlled, double-blind, parallel group 26-week clinical investigation to receive a single intra-articular injection of PVA Hydrogel or Synvisc-One®. Safety (both at the injection site (primary end-point) and overall) and efficacy (change in pain in the target knee (0-10 NRS), WOMAC Osteoarthritis Index (total and subscales) and Patient's Global Assessment of knee OA (0-10 NRS)) will be evaluated.

After signing an informed consent, patients will be screened at least 7 days before randomisation, when they will received a single intra-articular injection of either PVA Hydrogel or Synvisc-One® (1:1 allocation ratio) and will be then seen for follow-up 1, 2 and 4 days (this latter just in case of AE occurrence at the target knee) and 2, 4, 8, 12, 18 and 26 weeks after IA injection.

Eligibility Criteria

Inclusion Criteria

1. Signed and dated informed consent obtained before undergoing any clinical-investigation-related procedure.

2. Male or female aged between 40 and 80 years.

3. Documented diagnosis of primary OA of the knee, based on the clinical and radiological American College of Rheumatology (ACR) criteria for knee OA:

• Knee pain,
• X-ray osteophytes,
• at least one of the following: (a) age >50 years; (b) morning stiffness <30 minutes in duration; (c) crepitus on active motion.

4. Grade II-III according to the Kellgren and Lawrence classification (X-ray evidence at enrolment or within the previous 12 months).

5. Knee OA symptoms for at least six months.

6. Failure to respond (i.e. did not respond sufficiently) to analgesics and/or regular NSAIDs, or proven intolerance to regular use of NSAIDs or to weak opioids analgesics.

Exclusion Criteria

8. Ability and willingness to communicate, participate, and comply with the requirements and scheduled procedures of the clinical investigation.

(a) Medical history and Concomitant Diseases related criteria

1. Presence of isolated or predominantly symptomatic patellofemoral OA of the knee (i.e. pain when climbing stairs or forcing the patient to extend his leg when sitting on a low sit).

2. Presence of secondary osteoarthritis and/or other rheumatic diseases. In particular, history or presence of the following diseases should be excluded: septic arthritis, inflammatory joint disease, gout, recurrent episodes of pseudogout, Paget's disease of bone, articular fracture, ochronosis, acromegaly, haemocromatosis, Wilson's disease, primary osteochondromatosis.

3. Contralateral (i.e. non-target) knee pain >3 on the NRS

4. Any knee OA treatment for both knees (other than the clinical investigation viscosupplementation of the target knee) anticipated within the next 6 months.

5. Presence of pain (any severity) in the ipsilateral and/or contralateral hip.

6. Presence of disease of the spine or other lower extremity joints of sufficient severity to affect the clinical investigation assessments.

7. Anterior cruciate ligament repair, reconstruction or injury in the target knee within the previous 3 years.

8. Cartilage repair/surgery in the target knee within the previous 3 years.
