Spine fracture fix: new device aims to ease back pain
NCT ID NCT04821739
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a device called AGN1 LOEP SV Kit for people with painful spinal fractures caused by osteoporosis. The device is injected into the broken vertebra to stabilize it. Researchers will track pain relief over 12 months in 100 participants aged 50 and older.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AGN1 LOEP SV Kit (a device injected into the spine to stabilize the broken bone)
- What this could lead to
- If it works, this could offer a new option to reduce pain and stabilize spine fractures from osteoporosis without major surgery.
- What could go wrong
- This is an early-stage study with only 100 people and no comparison group, so results may not apply broadly. Risks include infection or device-related complications.

Inclusion Criteria: 1. Subject is a male or female 50 years of age or older at time of study treatment. 2. Criterion omitted 3. Subject has only one (1) acute VCF. Subjects are eligible if they have an asymptomatic healed VCF at any non-target vertebral level. 4. This VCF meets all of the following criteria: 1. Fracture due to diagnosed or presumed underlying osteoporosis 2. VCF from T1 to L5 inclusive 3. Fracture age ≤6 months at time of treatment 5. Target VCF shows loss of height in the anterior or middle portion of the vertebral body of not more than 50% based on X-ray at baseline. 6. Target VCF is acute or persistent (not healed), as demonstrated by T2 weighted STIR MRI, bone scan, CT, serial radiographs, or other imaging demonstrating acuity. 7. Subject has central pain upon palpation over the spinal process at the target vertebral body. 8. Subject has failed conservative medical therapy, defined as either having a VAS back pain score of ≥ 70 mm after 24 hours to 6 weeks of conservative care or a VAS back pain score of ≥ 50 mm after 6 weeks of conservative care. 9. Subject has an Oswestry Disability Index (ODI) score of ≥ 30%. 10. Subject is capable of giving written informed consent to participate in the study. 11. The subject's willingness, ability, and commitment to participate in screening, treatment, and all follow-up evaluations for the full length of the study has been documented. Exclusion Criteria: 1. Target VCF is due to underlying or suspected tumor. 2. Target VCF is due to high-energy trauma. 3. Target VCF is diagnosed as an osteonecrotic fracture. 4. Target VCF has segmental kyphosis of \> 30°. 5. Target VCF is unstable including split or burst fractures. 6. Subject has had any prior surgical treatment at the target VCF or adjacent vertebral level (above or below VCF). 7. Subject has neurologic symptoms, deficits, or radiculopathy related to the VCF. 8. Subject has spinal canal compromise causing clinical manifestations of cord, neural foramen, or nerve root compression at the level to be treated. 9. Subject has pain based on clinical diagnosis of herniated nucleus pulposus or severe spinal stenosis (progressive weakness or paralysis). 10. Subject has spondylolisthesis \> Grade 1 at target vertebral body. 11. Subject has pain due to any other condition that requires daily narcotic medication. 12. Subject has severe cardiopulmonary deficiencies. 13. Subject has a bleeding disorder. 14. Subject has a Body Mass Index (BMI) \> 35. 15. Subject has a history of metabolic bone disease other than osteoporosis (e.g., Paget's disease, renal osteodystrophy, or osteomalacia). 16. Subject has a history of tuberculosis spondylitis. 17. Subject has a history of any invasive malignancy (except non-melanoma skin cancer), unless treated with curative intent and with no clinical signs or symptoms of the malignancy for five (5) years. 18. Subject is on oral or parenteral immune-suppressive drugs. 19. Subject has an active bone infection at target VCF. 20. Subject has uncontrolled diabetes mellitus, as determined by the judgment of the Investigator. 21. Subject has severe renal insufficiency defined as an estimated glomerular filtration rate (eGFR) \< 30 mL/min. 22. Subject has a diagnosed calcium metabolism disorder. 23. Subject has known allergies to calcium-based bone void fillers. 24. Subject is pregnant or planning to become pregnant during participation in the study. 25. In the judgment of the Investigator, the subject is not a good study candidate (e.g., inability to maintain follow-up schedule, comorbidity or poor general physical/mental health, or drug or alcohol abuse issues). 26. Subject is currently enrolled in another interventional clinical study.
