Non Union Fracture Clinical Trial
Official title:
A Multi-centre, Open-label, Randomized, Comparative Clinical Trial of Two Doses of Bone Marrow Autologous MSC+ Biomaterial vs Iliac Crest Autologous Graft, for Bone Healing in Non-union After Long Bone Fractures
ORTHOUNION is a multi-centre, open, comparative, randomized, clinical trial with three parallel arms that aims to compare the efficacy of three treatments to enhance bone healing in patients with long bone non-union.
Bone injuries represent an important world medical problem producing significant healthcare and societal expenditure. While most bone injuries are not severe and are capable of healing through bone regeneration by natural callus formation with standard treatments, severe bone injuries may not heal, becoming an important unmet clinical need. Non-unions, or pseudarthrosis, may occur in 5% to 20% of long-bone fractures that fail to heal properly after more than 6 months, with morbidity, prolonged hospitalization, and increased expenses. The most commonly accepted standard augmentation to procure fracture and non-union healing consists of autologous bone grafting, obtained from the same patient in a different surgical site and transplanted to the reconstruction site. However, autologous bone grafting has some drawbacks (such as persistent pain, scar, late recovery, limited amount of bone, etc) and a limited regeneration efficacy (success rate of about 74%) and high societal cost. Culture-expanded autologous MSCs combined with biphasic calcium phosphate (BCP) biomaterial granules have been claimed as a solid regenerative medicine alternative to autologous bone grafting in non-unions, although current data are limited. In this context, the ORTHOUNION initiative focuses on the opportunity to test the hypothesis of superiority of MSC, the investigational ATMP, versus the currently accepted standard therapy, iliac crest bone autograft to biologically augment surgical treatment of long-bone non-unions. ;
