Study Summary

The primary purpose of this study is to evaluate the efficacy of rexlemestrocel-L+HA compared to control in reducing low back pain at 12 months post-treatment and safety of a single injection of rexlemestrocel-L+HA injected into a lumbar intervertebral disc compared to control through 12 months post-treatment.

Primary Outcome

Low back pain intensity will be measured using a VAS ranging from 0-100 millimeter (mm). A score of 0 represents no pain and 100 represents worst possible pain.
