STAND - Study of the AGN1 LOEP SV Kit Compared to PMMA in Patients With Vertebral Compression Fractures
This is a multicenter, single-blinded, randomized controlled clinical trial evaluating the safety and efficacy of the AGN1 LOEP SV Kit for the treatment of painful vertebral compression fragility fractures (VCFs). The objective of this study is to demonstrate non-inferiority of the AGN1 LOEP SV Kit for the treatment of VCFs to standard of care vertebroplasty treatment using bipedicular injection of PMMA bone cement.

- Accepts Healthy Volunteers
- Subject is a male or female aged 55 and 85 years, inclusive, of age at time of study treatment. 2. Subject has only one (1) acute VCF. Note that subjects are eligible if they have an asymptomatic, chronic VCF(s) at any non-target, non-adjacent vertebral level. 3. The acute VCF meets all of the following criteria: 1. Due to diagnosed or presumed underlying osteoporosis 2. T1 to L5 inclusively 3. Target VCF-related pain ≤ 6 months at time of study treatment 4. Target VCF shows loss of height of the vertebral body ≤ 50% based on X-ray at baseline. 5. Target VCF is acute or persistent (not healed), as demonstrated on imaging, including T2 weighted STIR MRI, bone scan or bone scan with SPECT/CT, serial radiographs, or other serial imaging demonstrating acuity. 6. Focal tenderness to palpation of the spinal process of the target VCF on the physical exam correlates with imaging. 7. Subject has failed conservative medical therapy (bed rest, observation, chiropractic care, orthotics, opioid and non-opioid analgesics, and/or physical 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 more than 6 weeks of conservative care. 8. Subject has an Oswestry Disability Index (ODI) score of ≥ 30% at baseline. 9. Subject is capable of giving written informed consent to participate in the study. 10. 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.
- Target VCF is unstable, including split or burst fracture. 2. Subject has a bleeding disorder. 3. Subject has an active infection of the spine or has an infection being actively treated with antibiotics. 4. Target VCF is due to underlying or suspected tumor. 5. Target VCF is due to high-energy trauma. 6. Target VCF is due to osteonecrosis. 7. Target VCF has a local kyphotic angle of > 30 degrees, measured as the angle between the superior endplate and inferior endplate at the target VCF. 8. Subject has had any prior surgical treatment at the target vertebral level or adjacent vertebral levels. 9. The pedicle(s) in the target vertebral body appear unable to safely accommodate transpedicular access instrumentation. 10. Subject has neurologic symptoms, deficits, or radiculopathy related to the VCF. 11. Subject has spinal canal compromise causing clinical manifestations of cord, neural foramen, or nerve root compression at the level to be treated. 12. Subject has pain, progressive weakness, or paralysis due to herniated nucleus pulposus or spinal stenosis. 13. Subject has spondylolisthesis > Grade 1 at target vertebral body. 14. Subject requires daily opioid medication for pain not related to the target VCF. 15. Subject has severe cardiopulmonary deficiencies. 16. Subject has a Body Mass Index (BMI) > 35. 17. Subject has a history of metabolic bone disease other than osteoporosis (e.g., Paget's disease, renal osteodystrophy, or osteomalacia). 18. Subject has a history of tuberculous spondylitis. 19. Subject has a history of invasive malignancy within the last five (5) years, other than non-melanoma skin cancer. Subject is not excluded if they have a history of malignancy over 5 years ago treated with curative intent and without clinical signs or symptoms since then. 20. Subject is on oral or parenteral immune-suppressive drugs. 21. Subject has uncontrolled diabetes mellitus. 22. Subject has severe renal insufficiency defined as an estimated glomerular filtration rate (eGFR) < 30 mL/min. 23. Subject has a diagnosed calcium metabolism disorder. 24. Subject has known allergies to calcium-based bone void fillers. 25. Subject is pregnant or planning to become pregnant during participation in the study. 26. In the judgment of the Investigator, the subject is not a good study candidate. (e.g. substance abuse or chemical dependency, inability to adhere to follow-up schedule, progression of the fracture between screening and the procedure visit). 27. Subject is currently enrolled in another interventional clinical study.
- Study Type
- Intervention Model
- Parallel Assignment
- Intervention Model Description
- Four hundred eight (408) eligible subjects at up to twenty (20) study sites will be randomized 1:1 for treatment using the AGN1 LOEP SV Kit (Intervention Group) or PMMA bone cement (Active Control Group).
- Primary Purpose
- Single (Participant)
- Masking Description
- Study subjects will not be informed of their treatment group assignment at the time of randomization or at any time before the subject's last office visit. The blind will be broken only if it is necessary to protect the safety or welfare of the subject as determined by the Investigator.
Treatment with AGN1 LOEP SV Kit
|The AGN1 LOEP SV Kit is intended for fixation of pathological fractures of the vertebral body using vertebral augmentation. Following saline lavage to create space, the AGN1 implant material is injected and hardens in situ to augment the fractured vertebral body. The AGN1 implant material is then resorbed and replaced with new bone.||
Treatment with PMMA bone cement
|High viscosity PMMA bone cement will be used for vertebral augmentation.||
