Trial overview
The source data includes three Phase 3 interventional trials that investigate Sodium Hyaluronate in different clinical settings.[1][2][3]
Two trials studied people with chronic mucopurulent discharge and/or discomfort of the ocular prosthesis socket, and one trial studied patients with knee osteoarthritis.[1][2][3]
All three studies were designed to compare patient outcomes after treatment, rather than to describe the substance itself.[1][2][3]
Eye prosthesis studies
The two eye prosthesis trials had the same title and studied people with chronic discharge and discomfort in the socket of an artificial eye.[1][2]
These studies compared Hylan eye drops, which are listed in the trial data as the Sodium Hyaluronate-related active control, with other treatments such as vitamin A ointment and low-dose steroid eye drops.[1][2]
One of these trials was completed and included 40 participants, while the other was withdrawn and planned to include 100 participants.[1][2]
The brief summary says the study aimed to test the effect of artificial tears, vitamin A ointment, and steroid drops in artificial eye wearers with chronic irritation and/or excess discharge.[1][2]
Knee osteoarthritis study
The third trial is a Phase 3 multicentre, randomized, open clinical trial in patients with knee osteoarthritis.[3]
This study compared allogenic mesenchymal cells, autologous mesenchymal cells, and an active control with hyaluronic acid, which is the term used in the trial data for the control treatment linked to Sodium Hyaluronate research.[3]
The study was authorised and planned to enroll 120 patients.[3]
The goal was to compare clinical, functional, and radiological response, meaning how patients feel, how they function, and what imaging tests show.[3]
What the trials measure
The main outcome in the eye prosthesis studies was the change in discomfort score and discharge score from baseline after 2 weeks of treatment.[1][2]
These scores are simple study measurements used to track whether symptoms get better or worse over time.[1][2]
In the knee osteoarthritis study, the main outcomes were pain intensity on the VAS pain scale, functional capacity and pain on the Lequesne scale, symptom burden and physical disability on the WOMAC scale, and lesion improvement or stabilization on T2-mapping MR images at 12 months.[3]
T2-mapping MR images are a type of MRI scan used in the study to look at tissue changes inside the knee joint.[3]
Study status and size
The trial statuses in the data were completed, withdrawn, and authorised.[1][2][3]
The planned or reported enrollment ranged from 40 to 120 participants, showing that these were relatively small to moderate Phase 3 studies.[1][2][3]
Across the source data, the trials focused on symptom relief, function, and imaging outcomes in clearly defined patient groups.[1][2][3]
