Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At week 0, participants with symptomatic primary knee osteoarthritis will be randomized to receive a single intraarticular injection of Articul One or with Synvisc-One Registered Trademark or Placebo. Total 30 subjects (20 in Articul One, 5 in Synvisc-One Registered Trademark, 5 in Placebo) will be enrolled in the study.
Once a participant qualifies to participate in the study, the site will receive the randomization number for the participant via the interactive web response system (IWRS).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A block randomization method will be implemented using SAS ver.9 or higher. The entire randomization-related procedure will be performed and managed by IWRS

Statistical methods / analysis
From previous studies that measured the WOMAC A change after Synvisc-One administration in patients with symptomatic primary knee osteoarthritis, the pre-dose to post-dose Week 12 score change was reported as 0.9+/-0.8 points, respectively(Chevalier). Therefore, this study assumed the expected for pre-dose to post-dose change in the WOMAC A score as 0.9 points, and the standard deviation for the change was assumed as 0.8 of standard deviations in prior studies.
Based on these assumptions and the significance level for a 2-sided test of 0.05, statistical power of 99%, the minimum sample size is calculated.
Considering drop-out rate of 25%, total 20 subjects were calculated.
In addition, this study is designed to exploratory comparison of the difference between Articul One vs Synvisc-One and Articul One vs Placebo. Thus total 10 subjects (5 in Synvisc-One, 5 in Placebo) additionally will be enrolled in the study.
The planned number of subjects is considered adequate to obtain data for effect size and sample size for subsequent next clinical studies.

For the efficacy assessment, the Full Analysis set is used as the main analysis set, and the Per Protocol set is also analyzed supportively and results are compared.

Summary
Brief summary
This study aims to investigate the effectiveness and safety of a single intraarticular injection of Articul One in comparison with Synvisc-One Registered Trademark or placebo for the treatment of symptomatic primary knee osteoarthritis. 30 subjects will be randomized to receive either Articul one , the experimental arm (20 subjects), Synvisc-One Registered Trademark, the active comparator arm (5 subjects), or Placebo (5 subjects). This will be done by analysing questionnaires to understand the severity of the disease status, pain and rescue medication diary, and side effects. Safety will be monitored during the treatment visits using standard measures, including physical exams, vital signs (including oral temperature), and side effect monitoring.

Subjects may be eligible to join this study if they are aged over 40 years, have knee pain due to osteoarthritis of the knee and are in otherwise general good health.

This study will investigate a single dose of Articul One in comparison with Synvisc-One Registered Trademark or placebo (a treatment with no active ingredients which looks like the real thing but it is not). This study is ‘double-blind’ which means the subject and the assessing doctor, together with the study staff will not know whether the subject is receiving Articul One, Synvisc-One Registered Trademark or placebo. The person who administers the injection will be unblinded (they will know what treatment the subject will receive) however, they will not allow the subject or the assessing team know which treatment is being received.

The study includes a screening visit (visit 1) to check eligibility and to explain the study.. There will be 1 treatment visit (visit 2) which will occur within 21 days of visit 1. There will also be 4 further visits to assess the safety and effectiveness of the treatment. These visits will occur at weeks 4, 12, 20 and 26.

During the follow up period, four clinic visits are required for: review of diary, medications, AEs;. Participants will record rescue pain medication in a daily diary.
