ClinicalTrials.gov ID: NCT07267793
What this study is testing
What is Synovian®?
Synovian® is an investigational medicine, given as an injectable medicine, being studied as a potential treatment for osteoarthritis.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This clinical trial aims to evaluate and compare the efficacy and safety of CartiPRO, an approved intra-articular atelocollagen injection, versus Synovian injection for the relief of knee pain in patients with knee osteoarthritis. The investigational device is administered intra-articularly, with a second injection given 24 weeks after the first dose.
