• 4. MRI finding of severe high-grade lumbar stenosis
• 5. Leg pain exceeding back pain
• 6. Pain worse with flexion maneuvers
• 7. Fracture of lumbar vertebrae
• 8. Inability to perform any of the assessments required for endpoint analysis.
• 9. Clinically significant abnormal screening laboratory or clinical assessment values
• 10.

• 29. History of drug abuse (illegal "street" drugs except marijuana, if it is legal to use in states where patient resides), or prescription medications not being used appropriately for a pre-existing medical condition or alcohol abuse (≥ 5 drinks/day for ˃ 3 months), or documented medical, occupational, or legal problems arising from the use of alcohol or drugs within the past 24 months
