A Randomized, Double-blind, Placebo-controlled, Phase 1/2a, Multi-center Clinical Trial for Evaluation of Safety, Tolerability, and Efficacy of CordSTEM-DD in Patients With Chronic Low Back Pain Due to Lumbar Intervertebral Disc Degeneration
The purpose of this clinical study is to evaluate the safety, tolerability, and efficacy of CordSTEM-DD, an allogeneic umbilical cord-derived mesenchymal stem cell, as a cell-therapeutic drug in patients with chronic low back pain due to lumbar intervertebral disc degeneration.
Recently, organic–inorganic hybrid lead halide perovskites have attracted great attention for optoelectronic applications, such as light-emitting diodes, photovoltaics and optoelectronics.
