简要总结
Performance of CCoat Intra-Articular Injections in Mild to Moderate Knee Osteoarthritis: A Prospective, Randomized, Double-Blind, Multi-center Trial
详细描述
The study aims to evaluate the performance of a single intra-articular injection of CCoat in patients with mild to moderate knee osteoarthritis over 26 weeks. Intra-articular injections are widely used for their localized efficacy and reduced systemic toxicity compared to oral treatments. Current treatments, including corticosteroids and hyaluronic acid, have limitations such as short-term effects and potential cartilage damage [1],[2],[3],[4]. Platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) offer promise but require further validation [5],[6],[7]. CCoat, a liposomal boundary lubricant, provides a novel approach by coating cartilage surfaces to reduce wear, offering mechanical protection without altering synovial fluid properties.
CCoat is a new intra-articular (IA) injectable joint lubricant for patients suffering from mild to moderate knee osteoarthritis (OA), developed by Liposphere LTD. CCoat is a liposomal boundary lubricant that coats the cartilage surface and temporarily protects it from further damage and degradation.
The performance and safety of CCoat device over 26 weeks is being evaluated in another multi-center, prospective, placebo controlled, randomized, double- blinded clinical study in 150 patients with mild to moderate OA of the knee (per study protocol # CLD0000616). As this study is ongoing, there is no currently available data related to the performance of the device. With regards to the CCoat's safety, in the interim analysis no safety concerns were raised.
This clinical investigation aims to further confirm the performance of CCoat when used as intended for the treatment of mild to moderate knee osteoarthritis (OA) in a larger patient population group, in comparison to a marketed hyaluronic acid product. This study is critical to further confirm the benefit-risk profile of the CCoat device as a valid therapeutic option for knee OA treatment, which remains a significant unmet medical need.

结局指标
主要结局
Change from baseline in Knee injury and Osteoarthritis Outcome Score (KOOS) Pain score at 12 weeks
时间窗: Time Frame: Day 0, up to week 12
The change in KOOS Pain score from baseline to 12 weeks visit will be compared between the treatment groups using a repeated measures analysis of covariance (ANCOVA, SAS® MIXED procedure). The model will include the following fixed effects: treatment group, visit, treatment group by visit interaction with Baseline KOOS Pain, K/L grade, and center entered as covariates. The principal statistical analysis will be a comparison between the treatment groups, derived from the visit by treatment group interaction term from the model. The adjusted mean change from baseline in KOOS Pain scores at 12 weeks post treatment initiation will be estimated from the model (LS Means) interaction term for each group as well as the difference between the adjusted means and presented together with 95% Confidence Intervals (CI's).
次要结局
- The secondary objective is to assess change from baseline to 2 and 12 weeks in KOOS Symptoms and ADL scores.(baseline to 2 and 12 weeks in KOOS Symptoms and ADL scores.)
