Clinical Trial Summary

This will be a multicenter, prospective, double blind, randomized phase 2/3 trial comparing culture-expanded allogeneic adult BM-MSCs with sham-treated controls. This trial will evaluate the efficacy of intradiscal injection of BM-MSCs in chronic low back pain due to lumbar degenerative disc disease (DDD) unresponsive to conventional therapy . Visual analog scale (VAS) and functional status (by Oswestry Disability Index - ODI) will be evaluated 12 months after treatment, defining responders in case of improvement of VAS for pain of at least 20% and 20 mm between baseline and month 12, or improvement of ODI of 20% between baseline and month 12.


Clinical Trial Description

Degenerative disc disease (DDD) presents a large, unmet medical need. One of the most important public health problems, it affects 70 million Europeans, accounts for 42% of patients with chronic low back pain and costs over $100 billion each year in the European Union. DDD results in a disabling loss of mechanical function. Today, no efficient therapy is available. The disease results from degeneration of cartilage discs with loss of the collagen matrix and nucleus pulposus chondrocyte. Chronic cases often receive surgery, which may lead to biomechanical problems and accelerated degeneration of adjacent segments. Our consortium partners have developed and studied stem cell-based, regenerative therapies with encouraging results in phase 1 and 2 trials. Patients exhibited rapid and progressive improvement of functional and pain indexes by 50% within 6 months and by 65% to 78% after 1 year with no side effects. In addition, MRI T2 relaxation measurements demonstrated a significant improvement of cartilage signal. To develop the world's first effective treatment of DDD, RESPINE aims to assess, via a randomized, controlled, phase 3 clinical trial including 112 patients with DDD, the efficacy of an allogenic intervertebral mesenchymal stem cell (MSC)-based therapy. This innovative therapy aims to rapidly (within 3 months) and durably (at least 24 months) reduce pain and disability. In addition, the consortium aims to provide new knowledge on immune response & safety associated with allogeneic BM-MSC intradiscal injection. ;
