Overview

The benefits of single or repetitive administration (1 to 6) can have similar result in terms of muscular strength and patients' quality of life improvement, benefiting of the advantages of polymerized polynucleotides (IRADYN) formulation.

Of all osteoarthritis' localization into human body, knee OA represents the most common OA localization. On 2014 the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) has suggested as first step of pharmacological treatment for knee osteoarthritis (OA) a background therapy with chronic symptomatic slow-acting drugs for osteoarthritis (SYSADOAs). In this class of natural compounds, hyaluronic acid (HA) has evidenced its efficacy after intra-articular (IA) administration in patient with mild to moderate knee OA . The filler used in this clinical investigation is using polymerised polynucleotides (PDRN) that has hydrophilic properties of polyanions; therefore, it can bind water molecules and provide a moisturising and lubricant effect. Its viscoelastic properties allow it to compensate for the loss of synovial fluid viscosity in the event of degenerative or trauma joint alterations. These actions reduce the mechanical stress on joints, thereby decreasing friction. This improves joint function and movement with significant relief of pain commonly associated with this problem. Moreover, the enzymatic degradation of the polynucleotide chain releases nucleotides into the synovial cavity. These nucleotides can bind water molecules and share the same viscoelastic properties as the entire chain, helping extend the duration of the effect. The benefits of single or repetitive administration (1 to 6) can have similar result in terms of muscular strength and patients' quality of life improvement, benefiting of the advantages of polymerized polynucleotides (IRADYN) formulation.

Outcomes

Primary Outcomes

Change in Range of Motion (ROM)

Change in Range of Motion (ROM) parameters, measured in degrees, using a goniometer (Active Knee Flexion - AKF, Passive Knee Flexion - PKF, Active Knee Extension - AKE, Passive Knee Extension - PKE)

Time frame: 14 weeks compared with baseline

Change in Visual Analogue Scale (VAS) for pain (at rest)

Visual Analogue Scale (VAS) for pain at rest is a 100 mm chart-line scale for the mentioned situation on which the subject must draw a mark on the scale to emphasize the intensity of the pain. Minimum score is 0 and it means no pain. Maximum score is 100 and represents the maximum pain that patient can suffer.

Time frame: 14 weeks compared to baseline

Secondary Outcomes

Absolute change in Visual Analogue Scale (VAS) for pain (on moving and on pressing)

Absolute change in VAS for pain (on moving and on pressing) at all visits compared to Baseline Visit. Visual Analogue Scale (VAS) for pain under pressure and at movement is a 100 mm chart-line scale for each of the mentioned situations on which the subject must draw a mark on the scale to emphasize the intensity of the pain. Minimum score is 0 and it means no pain. Maximum score is 100 and represents the maximum pain that patient can suffer.

Time frame: Up to 14 weeks

Absolute change in Knee injury and Osteoarthritis Outcome Score (KOOS)

KOOS consists of 5 subscales: Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport/Rec) and knee related Quality of life (QOL). Standardized answer options are given (5 Likert boxes) and each question is assigned a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.

Time frame: 6 weeks and 14 weeks compared to baseline
