ClinConnect Summary

This clinical trial is studying a new treatment called VIA Disc NP, which aims to help people with ongoing back pain caused by worn-out discs in their lower spine. This condition is known as degenerative disc disease. The goal of the study is to see how safe and effective this non-surgical treatment is for individuals experiencing pain that hasn’t improved with traditional care, like physical therapy or medication.

To be eligible for the trial, participants need to be between 22 and 85 years old and have had chronic lower back pain for at least six months due to early to moderate disc degeneration. They should also have pain that makes it hard to sit comfortably for more than 30 minutes. If someone joins the study, they will receive one treatment with the VIA Disc NP at their affected disc levels, which could be up to two levels. It's important to know that certain health conditions or recent treatments might prevent someone from participating, so potential participants will be carefully screened. Overall, this study could offer a new option for those struggling with chronic back pain.

• • Received any experimental drug or device to treat the same condition used within 6 months prior to the screening visit or during the course of the clinical trial
• • Other persistent pain/nerve issues including, for example, radiculopathy, leg pain, cauda equine syndrome, etc.
