NCT06431152

Brief Summary

The study aim to evaluate safety of exosomes (sEVs) from allogeneic mesenchymal stromal cells delivered by an intra-articular injection in the knee of patients with mild to moderate symptomatic osteoarthritis. The sEVs will be produced in a GMP-facility. The investigators expect to enroll 12 patients in this phase 1 trial open label dose-escalation pilot and the follow-up will be up to 12 months.
