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.

Detailed Description

The clinical investigation will represent a Phase 1 trial focusing on small extracellular vesicles derived from mesenchymal stem cell (MSC-sEV) in patients with symptomatic Kellgren II-III knee OA. The phase 1 component of the study will be an open-label dose escalation pilot study in which three cohorts of subjects with OA will receive increasing doses of UC-MSC-sEV administered as a single intra-articular (IA) injection. Each cohort will comprise four participants. Eligible study subjects will be enrolled at the "Clinica Universidad de los Andes".

The small extracellular vesicles derived from umbilical cord mesenchymal stem cell (UC-MSC-sEV) will be prepared in the "Clinica Universidad de los Andes" GMP facility. The sEV-based therapeutic for clinical use will be manufactured in compliance with standardized procedures based on Good Manufacture Practice (GMP) regulations and all quality controls aforementioned. The sEV therapeutic will be transported to the patient administration site under controlled conditions, ensuring maintenance of a temperature range between 2-8°C. The sEV injection is expected to be administered within the first 6 h of product manufacture.

The primary study endpoints of this trial will focus on the safety, feasibility, and toxicity of the sEV-based product. The phase I will examine (1) the incidence of immediate post-infiltration adverse reactions in patients; (2) the occurrence of synovitis post-infiltration in patients at 24 and 48 hours, as well as on days 7 and 15; (3) the frequency of post-infiltration pain reported by patients at 24 and 48 h, and on days 7 and 15; and (4) the prevalence of adverse events related to sEV therapy occurring beyond IA infiltration at 24 and 48 h, and on days 7 and 15, as well as at months 2, 4, 6, 8, 10, and 12. The secondary study endpoint will be determine the optimal dose for phase II trials. The criteria that will be considered are (1) Safety profile at infiltration at 24 and 48 h, and on days 7 and 15, as well as at months 2, 4, 6, 8, 10, and 12; (2) changes in WOMAC scores at months 2, 4, 6, 8, 10, and 12; and (3) alterations in the Visual Analog Scale (VAS) pain scores at months 2, 4, 6, 8, 10, and 12.
