Chronic Low-back Pain Clinical Trial

Official title: Intervertebral Disc Regeneration Mediated by Autologous Mesenchymal Stem/Stromal Cells Intradiscal Injection: a Phase IIB Randomized Clinical Trial - DREAM Trial

Status Recruiting

Clinical Trial Summary

DREAM is a phase II B efficacy monocentric, prospective, randomized, controlled double blinded trial, comparing intra-discal autologous adult bone marrow mesenchymal stem cells (BM-MSC) therapy and sham treated controls in subjects with chronic (> 6 months) Low Back Pain (LBP) due to lumbar multilevel (max. 3 levels) intervertebral disc degeneration (IDD) unresponsive to conventional therapy.

Duration of the recruitment period has been estimated to be 12 months. The efficacy of intradiscal injection of autologous BM-MSC in reducing chronic LBP due to multilevel lumbar IDD will be evaluated after 24 months in terms of pain relief (VAS), functionality (ODI) and quality of life (SF36).

Clinical Trial Description

Low back pain (LBP) is the global leading cause of disability, and furthermore rates sixth in terms of overall disease burden, in both developed and developing countries. LPB is a condition of all ages, from children to elderly, affecting 60-70 percent of the global population during life, and ~700 million people each year. LBP prevalence increases with age, and with populations ageing worldwide, the societal and economic burden associated with LBP will increase substantially over coming years.

Current LBP therapies are aimed at pain reduction, and do not provide restorative treatment. Such conservative strategies (e.g. painkillers and musculoskeletal rearrangement by manual and physiotherapy) rarely address the actual cause of LBP.

In a healthy spine, intervertebral discs (IVDs) separate the vertebrae to provide complex spinal flexibility while supporting large spinal loads. Intervertebral disc degeneration (IDD) is widely recognized as a major contributor to LBP, responsible for at least 40 percent of LBP cases. A key characteristic of IVD degeneration is loss of matrix integrity, thereby causing biomechanical functional failure.

Today, no therapy can restore IVD function or provide long-term relief from symptomatic IDD. New treatment strategies concentrate on treating IDD at an early stage. Stem cell research offers exciting possibilities, and advanced cell-based therapies are considered highly promising strategies in treating IVD degeneration and LBP. Encouraging results suggest that cell-based, regenerative therapies may provide the world first effective therapy for this common and debilitating disease.

The objective of DREAM is to generate efficacy and tolerability profiles of a single injection of 15 million of cells/ml of autologous BM-MSC for each disc affected by IDD (up to 3 discs) versus sham procedure. The potential of BM-MSC to lead to a disease-modifying therapeutic option for the treatment of this chronic and debilitating disease will be assessed by Magnetic Resonance Imaging (MRI) after 6 months, 1 and 2 years. ;
