VIA Disc NP is a non-surgical intervention intended to supplement nucleus pulposus tissue in degenerated intervertebral discs.
This is a randomized, sham-controlled, multi-center, double-blind clinical trial with an open label roll-in period of one participant per site in which participants with lumbar discogenic pain associated with DDD will receive one VIA Disc NP treatment to each affected level (up to 2 levels). Participants enrolled after the roll-in stage will be randomized on a 2:1 basis to receive either a single VIA Disc NP intradiscal injection at 1 or 2 levels or the sham procedure at 1 or 2 levels. At 12 months, participants in the sham arm with continued symptoms may cross-over, receive VIA Disc NP, and will restart the study visit schedule, completing an additional 12 months of follow-up post-cross-over.
