About

Allogeneic mesenchymal trophic factors (MTF) from human umbilical cord tissue-derived mesenchymal stem cells (UC-MSC) injected into the knee joints of 20 patients (group 1) or injected subcutaneously into 20 patients (group 2) is a safe and useful procedure for inducing joint function improvements in osteoarthritis (OA) patients with grade 2, 3, or 4 radiographic OA severity.

Full description

The proposed study will assess primary safety and secondary efficacy endpoints of allogeneic UC-MSC-derived MTF administered to two arms osteoarthritis patients with grade 2, 3, or 4 radiographic OA severity (20 per arm). The first arm will receive an intra-articular injection of MTF into the knee joint under fluoroscopy. The second arm will receive 12 subcutaneous MTF injections, once per week.

For both arms, the primary objective of safety will be defined as freedom from treatment associated adverse events for the period of one year. The secondary objective of efficacy will include evaluation at baseline and at months 3 and 12 of efficacy endpoints of joint function improvement as assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
