Brief summary: Osteoarthritis (OA) is a chronic degenerative joint disease characterized macroscopically by progressive damage of articular cartilage, joint space narrowing, subchondral bone remodelling, joint marginal osteophyte formation and synovitis. It is also characterized by a decrease of the concentration and molecular weight of the hyaluronic acid in the synovial fluid which ultimately leads to poor viscoelastic properties of synovial fluid and induction of proinflammatory pathways.

The intra-articular injection of viscosupplementation gel (mainly exogenous hyaluronic acid) represents one of the most used therapeutic strategies to treat osteoarthritis symptoms.

Several studies on knee Osteoarthritis, have shown that one or more weekly injection of viscosupplementation gel significantly relieves articular pain and ameliorates mobility and joint function for at least 6 months and more. Repeated courses of intra-articular injections are an effective and safe treatment for knee osteoarthritis symptoms.

Based on studies conducted on intra-articular viscosupplementation gels, the most common side effects expected are local transient and short-lived adverse events such as pain, swelling and arthralgia in the site of administration, which are fully reversible in the days following the injection. Furthermore, such local effects may occur in a minority of cases and are usually treated conservatively with ice, non-steroidal anti-inflammatory drugs, and relative rest.

Detailed description: Pivotal clinical investigation, interventional, prospective, comparative, single-blinded, controlled with two arms, randomized, multicentre clinical trial designed to assess the performance and safety of ABIO3419 for the treatment of osteoarthritis of the knee.

  1. Non-severe Grade 2 to 3 osteoarthritis of the knee according to the Kellgren-Lawrence (KL) classification, confirmed by an extension face X-rays shot, supported by flexion face X-rays shot (optional) obtained within 6 months from the screening visit.
  2. Subjects suffering from OA symptoms of the target knee for at least 6 months prior to the screening visit.

* a dedicated pain relief medicine consumption.
* 3. Subject suffering from a severe or progressive disease or any other pathology which, according to the investigator, may interfere with evaluation of the results of the study: diabetes, autoimmune pathology, cardiac pathologies, hepatic deficiency, epilepsy, porphyria, rheumatoid arthritis or other systemic inflammatory process.
* 4. Subject who has a known history of severe multiple allergies, angioedema or anaphylactic shock according to the investigator opinion.
