Clinical Efficacy and Safety of NEOIAL HC for Intra-articular Use in the Treatment of Severe Knee Osteoarthritis

Nextrasearch S.r.l.s.15 enrolled

Overview

Osteoarthritis (OA) is one of the most frequent causes of pain and disability in adults. According to the Osteoarthritis Research Society International (OARSI), at least 40% of people over the age of 65 suffer from symptomatic osteoarthritis of the hip or knee. Knee osteoarthritis (OA) is the eleventh leading cause of years lived with disability according to the World Health Organization. The guidelines show that treatment with intra-articular injections of hyaluronic acid (HA) leads to a slow, prolonged pain relief (up to six months after the first injection); On the other hand, there is little evidence in the literature about the intra-articular use of isolated collagen or in combination with hyaluronic acid in the treatment of knee osteoarthritis. The present study showed a clinically good safety profile and provided preliminary evidence of the efficacy of NEOIAL HC for the treatment of symptomatic knee OA

Interventions

Patients with severe knee osteoarthritis were enrolled in the clinical study and treated with 3 injections of 40 mg NEOIAL HC (HA sodium salt at 2% with two molecular weights 20% with pm at 400 kD and 80% between 1200 and 1500 kD t + collagen) at a distance of 1 week from each other, followed by a fourth infiltration of the same product at a distance of 1 month from the third.Patients were followed up with baseline clinical evaluation, reporting of adverse events after each single infiltration and subsequently at the end of treatment, 3, 6 months follow-up.

Outcomes

Primary Outcomes

VAS score

The primary objective in the study was to evaluate the mean changes from baseline at Month 3 in VAS Pain Subscale Score

Time frame: 6 months

Secondary Outcomes

Knee Injury and Osteoarthritis Outcome Score (KOOS)

The KOOS is self-administered and assesses 5 domains: pain, symptoms, activities of daily living (ADL), sport and recreation function, and knee-related quality of life. This scale is used to evaluate knee function in terms of activities of daily living (ADL).

Time frame: 6 months
