Safety and Efficacy Study of Rexlemestrocel-L in Subjects With Chronic Discogenic Lumbar Back Pain (MSB-DR003)
MesoblastThe Ainsworth Institute of Pain Management has been selected to join a phase 3 clinical trial studying the safety and efficacy of mesenchymal stems for the treatment of back pain.  This study is being conducted in several cities around the country; we are the only cite in the tri-state area!
Stem cell therapy is being investigated to treat everything from Parkinson’s Disease to heart disease.  There are several different types of stem cell therapy – some that use the bodies on cells to regrow damaged tissue and heal it, while others focus on using pre-grown stem cells that can used like medication to repair the body,  

Each of the bones in the spine is cushioned from one and other by intervertebral discs.  These discs can become damaged in a variety of ways: a car accident, playing golf, bending down to pick up something heavy, etc.  This damage commonly presents as a herniation, aka “a slipped disc.”  This will cause the disc to push out into the spinal cord or a nearby nerve root causing a characteristic pain like sciatica.  Other times, the disc can develop small tear from the inside causing it to become acutely tender causing pain in and around that disc in the low back – we call this discogenic pain.  Over time, damaged discs will lose the nature water contained inside them give them the ability to provide cushion to the spine – this is called degenerative disc disease.
Traditionally, the only way to treat a damaged and painful disc is:

Physical Therapy
Spinal Fusion
Disc Replacement

The above treatments can only treat the pain, not repair the damage.  Once a disc becomes damaged, it will stay that way…indefinitely.   Currently, there is nothing known to man that has been proven to cause a damaged disc to go back to the way it was before the injury.
The scientists at Mesoblast have developed a line of stem cells that can be used “off the shelf” and injected into damaged discs of of the spine.  This clinical trial is a prospective, multi center study focusing on whether or not these cells are effective in repairing damaged discs in the spine, potentially eliminating low back pain.

Low Back Pain

Nine out of 10 Americans will experience back pain in their lives and it is the 5th most common cause for a visit to the doctor. Severe back pain can become so debilitating that simple tasks such as bending down to pick something up or walking to the store can become next to impossible. Luckily, there are many treatment options available to help you get back to feeling more like you.

Can I Participate in this Study?

Must be 18 years of age or older
Chronic low back pain for at least 6 months
A confirmed diagnosis of degenerative disc disease from L1 to S1- -with one symptomatic disc
Failed at least 3 months of conservative therapy

Details of the Study
Patients who qualify for the study will be randomized to receive either a single injection of rexlemestrocel-L into a damaged disc, an injection of rexlemestrocel-L plus hyaluronic acid, or an injection of saline. Patients will then be followed for 12 months.
