What this trial studies

This pilot study evaluates the safety and feasibility of umbilical cord Wharton's Jelly allograft injections in 100 participants suffering from chronic lumbar pain. Participants will receive a series of lumbar injections and will be monitored for one year to assess safety, pain relief, and functional improvements. The study is open label and non-controlled, focusing on the effects of the treatment without a comparison group.

Who should consider this trial

Good fit: Ideal candidates are adults over 20 years old with chronic lumbar pain and a pain score of 4 or more on the Numeric Pain Rating Scale.

Not a fit: Patients who have taken pain medications or NSAIDs within two weeks prior to the injection date may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new, effective option for patients suffering from chronic low back pain.

How similar studies have performed: While this approach is novel, similar studies exploring the use of allografts for pain management have shown promising results.
