Performance and Safety of HyalganBio® Intra-Articular Injections as Add-On to Physical Exercise for Symptomatic Glenohumeral Osteoarthritis

Résumé succinct

This investigation evaluates performance and safety of three intra-articular injections of HyalganBio®, combined with a Physical Exercise Program (PEP) in subjects with glenohumeral osteoarthritis. The main goal is to see whether patients improve shoulder function six months after the first injection, compared with patients who only follow the exercise program. Improvement is measured using the Constant-Murley Score (CMS). Participants first attend a screening visit and, if they meet all criteria, they are enrolled. Within 14 days, they are randomly assigned to one of two groups: group 1 receives three weekly HyalganBio® injections and performs the PEP three times a week for 60 days, recording adherence in a diary; group 2: performs the same PEP schedule and also records adherence in a diary. Follow-up visits take place at 2, 4, and 6 months after the first injection, with additional telephone check-ins at 1 and 3 months.
