Clinical Trial Evaluating the Safety and Efficacy of Nucleus Pulposus Allograft in Participants With Degenerative Disc Disease (RESTORE)

Randomized, Sham-Controlled, Multi-Center, Double-Blind Clinical Trial Evaluating the Safety and Efficacy of Nucleus Pulposus Allograft to Supplement Nucleus Pulposus Tissue in Participants With Lumbar Discogenic Pain Associated With Degenerative Disc Disease

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: VIA Disc NP; A single dose, intradiscal delivery of 100mg of VIA Disc NP mixed with sterile saline according to product Instructions for Use (IFU) and administered at up to two affected levels, L1-S1.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Primary Effectiveness Endpoint - Proportion of participants achieving MCID in VAS score from baseline to 12 months.	The primary efficacy endpoint is the proportion of participants who achieve a minimal clinically important difference (MCID), defined as at least a 30% reduction in back pain VAS score from baseline to 12 months, in the VIA Disc NP group compared to that in the sham-control group.	Baseline to 12 Months
Primary Safety Endpoint - Proportion of participants reporting treatment-related AEs at 12 months.	The primary safety endpoint will be the proportion of participants that experience one or more treatment-related (Investigational Product (IP) or procedure), adverse events (AE) in the VIA Disc NP group compared to the sham-control group at 12 months.	Baseline to 12 Months
