Comparing StromaForte (donor bone-marrow mesenchymal stromal cells) versus hyaluronic acid injections for knee osteoarthritis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label, two-treatment-group Phase 2/3 trial compares an allogeneic bone-marrow-derived mesenchymal stromal cell product (StromaForte) with standard hyaluronic acid injections for symptomatic knee osteoarthritis. Adults with Kellgren-Lawrence grade I–IV knee OA and activity-related pain (VAS ≥40) who meet BMI and other eligibility criteria will be enrolled and assigned to receive one of the two intra-articular injection treatments. Participants will undergo baseline radiographic confirmation (images no older than three months) and will be followed for safety and symptom and function measures across the trial period. The protocol emphasizes both efficacy and safety monitoring given the cell therapy intervention.
