Could a disc injection replace surgery for back pain?
NCT ID NCT06615505
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a single injection of VIA Disc NP, a processed human disc tissue, for people with long-term lower back pain from degenerated discs. About 121 participants will receive either the injection or a sham procedure. The goal is to see if the injection safely reduces pain and improves function over 6 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VIA Disc NP (a processed human disc tissue allograft injected into the disc)
- What this could lead to
- If it works, this could offer a new, non-surgical option to reduce back pain and improve function for people with degenerated discs.
- What could go wrong
- This is an early phase 2 trial with only 121 participants, so results may not apply to everyone. The sham procedure may also produce some benefit, making it hard to prove the treatment works.

Key Inclusion Criteria: 1. Age 22 to 85 years old 2. Diagnosis of early to moderate DDD, Modified Pfirrmann Grade 3-7 3. Chronic axial midline low-back pain with or without referred non-radicular leg pain for at least 6 months prior to screening; unresponsive to at least 3 months of conservative care 4. Positive hip flexion test as confirmed with the Neurologic Exam indicating positive provocation with sustained hip flexion at the time of screening 5. Demonstrated intolerance to sitting for more than 30 minutes at a time based on self-report or assessed by a qualified healthcare professional at the screening visit 6. Low-back pain severity score of ≥ 40 to ≤ 90 mm on the VAS at the time of Screening 7. ODI score of ≥ 40 to ≤ 80 at the time of Screening Key Exclusion Criteria: 1. Contraindication to MRI for any reason 2. Contraindications to the proposed sedation/anesthetic protocol 3. Symptomatic involvement of more than two lumbar discs 4. Fracture of the lumbar spine, previous lumbar spine surgery or previous treatment of the target disc(s) 5. Grade 2 or higher spondylolisthesis at the target disc, lumbar spondylitis or other undifferentiated spondyloarthropathy, or Type III Modic changes around the target disc 6. Clinical suspicion of a full thickness annular tear at the target disc or other abnormal disc morphology 7. Clinical suspicion of facet pain as primary pain generator 8. Women who are pregnant or breastfeeding at the time of enrollment and/or plan to become pregnant during the study. Pregnancy is confirmed by: * A positive pregnancy test during the screening visit * Self-reported pregnancy 9. Women of childbearing potential (WOCBP) who are not using a reliable form of contraception (as determined by the Investigator)
