简要总结
The OLE was aimed to assess long-term safety and efficacy of one and two courses of IA HBISA in patients with knee osteoarthritis.
详细描述
HBISA (polyacrylamide hydrogel) endoprosthesis of synovial fluid NOLTREX™ is intended for the symptomatic treatment of adult patients with osteoarthritis (OA) reducing pain and improving mobility.
The aim of the 6-month OLE was to evaluate the long-term safety and efficacy of one and two courses of IA Polyacrylamide hydrogel with silver ions in patients with knee osteoarthritis who had received at least one IA injection of NOLTREX™ and completed the visit 5 in the IA/PAAG-SI/OA/2019 study.
In OLE patients who had received a course of treatment (one or two weekly intra-articular injections of 4.0 NOLTREX™ depending on the stage of OA and the clinical response to treatment) in the parent study might receive a single repeat course of NOLTREX™ at the visits 1/2 or 3/4 when clinically indicated. The WOMAC was the primary outcome measure.

研究组 & 干预措施
Medical Device: HBISA (polyacrylamide hydrogel) synovial fluid endoprosthesis NOLTREX™
Sixty-five (65) patients were included in the study and divided into three groups based on the number of NOLTREX™ courses received:
- Group A consisted of 5 patients who received 2 NOLTREX™ courses, the first course in the IA/PAAG-SI/OA/2019 study and the second one at Visits 1/2 of OLE (IA/PAAG-SI/OA/2020) study.
- Group B comprised 43 patients who received 2 NOLTREX™ courses, the first course in the IA/PAAG-SI/OA/2019 study and the second one at Visits 3/4 of OLE.
- Group C consisted of 17 patients who had received only 1 NOLTREX™ course in the parent study.
干预措施: Hydrous biopolymer with silver ions "Argiform" (HBISA) endoprosthesis of synovial fluid NOLTREX™ (Device)
结局指标
主要结局
Change in the Total WOMAC Score (WOMAC-T)
时间窗: baseline (OLE visit 0 and visit 1 study 1 [week 1]), OLE visits 3 (week 11) and 5 (week 23)
Mean change in WOMAC-T from baseline (visit 0 \[screening\] of OLE and visit 1 (week 1) of the parent study) to visit 3 (week 11) and visit 5 (week 23). Patients were asked to complete the questionnaire during the study visits. The Western Ontario and McMaster Universities Osteoarthritis Index Version 3.1 Visual Analog Scale Format (WOMAC VA 3.1) applies a 100-mm VAS and consists of three subscales: pain (5 questions), stiffness (2 questions), and physical function (17 questions). The scores for each subscale are summed up, with a possible score range of 0-500 for Pain, 0-200 for Stiffness, and 0-1700 for Physical Function. Higher scores represent worse pain, stiffness, and functional limitations. A sum of the scores for all three subscales gives a total WOMAC score (0-2400), where 0 represents the best and 2400 the worst possible health status. The higher the score, the poorer the function. Therefore, an improvement was achieved by reducing the overall score.
