Clinical Trial 50257

Santa Monica, CA 90403


We are currently recruiting for a facet joint osteoarthritis study testing investigational drug XT-150. This treatment is for adult participants experiencing low back pain due to inflammation caused by the facet joint osteoarthritis (FJOA) who are eligible for intra-articular glucocorticoid steroid injection, or radiofrequency ablation of medial branches of the primary dorsal ramus. The possible benefits of this clinical study include longer-term relief in individuals experiencing pain from facet joint osteoarthritis.

Subjects will be evaluated at baseline and followed through 9 months to establish safety and efficacy of the treatment. The study drug will be administered as bilateral injections to the facet joints at the determined level, with a repeat injection at the 90 day mark.

  • Be age 18 to 90 years old
  • Have severe facet arthropathy
  • Low back pain worsened by activity or motion of region
  • No prior history of lumbar fusion surgery
  • No radiofrequency ablation within the last 12 months
