About this study
Official title: Intra-Articular Hyaluronic Acid (ArtiAid® Plus) for Knee Osteoarthritis: A Post-market, Open-Label, Long-Term Historical Control Study
The goal of this open-label, post-market clinical follow-up study is to demonstrate the safety and performance of ArtiAid® Plus Intra-articular Injection in patients with knee osteoarthritis(OA). The main questions it aims to answer are:
- the safety profile of ArtiAid® Plus;
- the clinical performance of ArtiAid® Plus, such as pain relief and satisfaction of treatment.
Participants will receive weekly injections of ArtiAid® Plus for 3 weeks and be follow-up for 26 weeks.
Read the detailed description
An open-label study will be performed in single center to monitor about 60 patients with knee osteoarthritis(OA), each treated with 3 injections of ArtiAid® Plus 1.5% (MAXIGEN BIOTECH INC., Taiwan). Follow-up visits will be at 4 weeks, 12 weeks(a telephone contact by the investigator) and 26 weeks after the injections. The primary endpoint of this study is to monitor the adverse events after injecting ArtiAid® Plus. The secondary endpoints of this study are demonstrating the clinical performance of ArtiAid® Plus, such as resting knee pain and satisfaction of treatment by using the visual analog scale (VAS). Analysis of variance (ANOVA) will be applied to the clinical data and T-test will be used to test for the differences between baseline and each visit. The paired student t-test was used to analyze variations in each group over a period of time. Statistical significance was established at p < 0.05.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ArtiAid® Plus Intra-articular InjectionDevice
Inject ArtiAid® Plus in the affected joint at weekly interval for 3 weeks
| Study group | Role | What they receive |
|---|---|---|
| ArtiAid® Plus group | Experimental | Each pre-filled syringe contains 15 mg/ml (1.5%) sodium hyaluronate, subjects received one injection per week for three weeks. Receives: Device: ArtiAid® Plus Intra-articular Injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Treatment-related Adverse Events
The adverse events are defined as any unfavorable sign occurrence in a subject after treatment. The investigator assesses the severity and the relationship of each event to the use of the study device.
Measured: 0 week to 26 weeks after injections
Secondary outcomes (2)
Resting knee pain: VAS (visual analog scale)
Current level of resting knee pain will be assessed by a patient-reported VAS (visual analog scale), subjects mark on a 0-100 mm line, where 0 represent "no pain" and 100 represents "maximum pain". The VAS pain score will be assessed at baseline 4 weeks and 26 weeks after injections.
Measured: Baseline, 4 weeks, and 26 weeks after injections
Satisfaction of treatment: VAS (visual analog scale)
The satisfaction of treatment will be assessed by a patient-reported VAS (visual analog scale), subjects mark on a 0-100 mm line, where 0 represent "least satisfied" and 100 represents "highest satisfaction". The VAS pain score will be assessed at 4 weeks and 26 weeks after injections.
Measured: 4 weeks, and 26 weeks after injections
