Effect of Abaloparatide on Lumbar Disc Degeneration

Withdrawn before enrolling · Phase 2 · Has a placebo group

Conditions studied: Degeneration Disc Intervertebral

In brief

Low back pain is a major public health issue as the leading cause of disability globally. Degeneration of intervertebral disc (IVD) disorder is once source of low back pain. Current treatment options for low back pain secondary to degeneration of intervertebral disc include conservative care, steroid injections, prescription pain medications, physical therapy, or surgery, such as discectomy or laminectomy. Treatments focus on addressing manifested symptoms rather than functional causes, and symptomatic treatment of discogenic low back pain is less than ideal. The investigators have recently found that parathyroid hormone (PTH) effectively attenuates disc degeneration in aged mice. This clinical trial will test if 3-months of daily PTH-related protein (PTHrP), abaloparatide will improve pain, function, and disc health in people with low back pain secondary to lumbar disc degeneration.

You may qualify if…

• Identifiable change in disc morphology as defined by MRI consistent with early degenerative disc disease as defined by both Modified Pfirrmann (MRI) score of 2-3 (Graded 1-8, where 1= hydrated healthy disc, 8 = dark, dehydrated disc) and Modic Grade II change or less
• Single- or two-level DDD at lumbar spine
• < 30% vertebral body height loss
• Oswestry disability index score > 30
• Failed > 3 months of appropriate non-operative care (i.e. pain medication, local drug injections, physical therapy)
