Overview
VIA Disc NP is an off-the-shelf minimally processed human nucleus pulposus tissue allograft intended to supplement degenerated intervertebral discs.
The study is a randomized, double-blind, sham-controlled, multi-center study in participants with symptomatic lumbar intervertebral disc degeneration (> 6 months) and unresponsive to conservative therapy for at least 3 months. Participants will be randomized on a 1:1 basis to receive either a single VIA Disc NP intradiscal injection at 1 or 2 levels or a sham procedure at 1 or 2 levels.
