Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

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.

Primary outcomes1

Outcomes the sponsor listed as primary.

Percentage of participants with improvement in symptomatic or radiographic symptoms as indicated by composite score aggregated from the Oswestry Disability Index (ODI) and Pfirrmann grading system
Time frame · 6 months
Registry description
Composite score will be graded as a score of 0, 1 or 2, whereas: * 0 (no improvement) = less than 15 point score improvement on Oswestry Disability Index (ODI) and less than 1 grade improvement on Pfirrmann grading system. * 1 (some improvement - symptomatic or radiographic) = 15 point or greater improvement on ODI score OR at least 1 grade improvement on Pfirrmann grading system. * 2 (definite improvement) = 15 point or greater improvement on ODI score AND 1 grade or greater improvement on Pfirrmann grading system. ODI is scored on a scale of 0-100 with higher scores indicating worse disability. A decrease in ODI of 15 points is considered a clinically (symptomatic) meaningful improvement by the FDA. The modified Pfirrmann Grading system is an MRI based score (radiographic) of disc degeneration on a scale of 1-8, with higher scores indicating more severe degeneration, such that improvement is by decreasing score.

Secondary outcomes(11)

Change in disability as assessed by ODI
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on disability will be assessed by absolute difference in ODI from baseline in abaloparatide versus placebo group, reported as average per group. ODI assessed pain related disability is scored on a scale of 0-100 with higher scores indicating worse disability.
Change in clinically significant improvement in disability as assessed by ODI
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on disability will be assessed by percentage of patients with 15 point or greater improvement in ODI from baseline in abaloparatide versus placebo group. ODI assessed pain related disability is scored on a scale of 0-100 with higher scores indicating worse disability. A decrease in ODI of 15 points is considered a clinically meaningful improvement by the FDA.
Change in pain as assessed by pain numerical rating scale
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on disability will be assessed by absolute difference in pain numerical rating scale from baseline in abaloparatide versus placebo group, reported as average per group. The pain numerical rating scale assesses pain intensity on a scale of 0-10 with higher scores indicating worse pain.
Change in disability as assessed by PROMIS-29 score
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on disability will be assessed by absolute change in PROMIS-29 score from baseline in abaloparatide versus placebo group, reported as average per group. The PROMIS-29 is a multi-dimensional quality of life instrument that assesses pain, physical function, fatigue, anxiety, depression, sleep disturbance, and social participation on a scale of 0-100 with higher scores indicating more disturbances of that dimension.
Change in radiographic markers of Degenerative Disc Disease (DDD) as assessed by absolute difference in Pfirrmann Grading system
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on changes in radiographic markers of DDD will be assessed by absolute difference in modified Pfirrmann Grading system from baseline, reported as average per group. The modified Pfirrmann Grading system is an MRI based score of disc degeneration on a scale of 1-8, with higher scores indicating more severe degeneration.
Change in radiographic markers of DDD as assessed by improvement in Pfirrmann Grading system
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on radiographic markers of DDD will be evaluated using the percentage of patients with 1 grade or greater improvement in modified Pfirrmann Grading system from baseline in the abaloparatide versus placebo group. The modified Pfirrmann Grading system is an MRI based score of disc degeneration on a scale of 1-8, with higher scores indicating more severe degeneration.
Change in radiographic markers of DDD as assessed by average absolute difference in Modic score
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on radiographic markers of DDD will be assessed by absolute difference in Modic Score from baseline, reported as average per group. Modic score is an MRI based score characterizing the vertebral endplate. Modic score correlates with progressive degenerative changes in the endplate, where 0 = normal; 1= hypervascular; 2 = fatty infiltration; 3 = sclerosis.
Change in radiographic markers of DDD as assessed by Modic score
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
The efficacy of abaloparatide on radiographic markers of DDD will be evaluated using percentage of patients with 1 grade or greater improvement in Modic Score from baseline in the abaloparatide versus placebo group. Modic score is an MRI based score characterizing the vertebral endplate. Modic score correlates with progressive degenerative changes in the endplate, where 0 = normal; 1= hypervascular; 2 = fatty infiltration; 3 = sclerosis.
Change in pain management based on analgesic usage
Time frame · Baseline, 3 months, 6 months, 12 months
Registry description
Evaluate change in pain management in abaloparatide versus placebo groups based on change in the dosage of analgesic used and the number of days of back pain (longer than 30 min/day) in week prior to baseline compared to week prior to 3-, 6-, and 12-month visits.
Requirement of surgical intervention for back pain by patients
Time frame · 12 months
Registry description
Proportion of patients proceeding to a surgical intervention within the 12-month study period in the abaloparatide versus placebo group will be assessed by percentages per arm
Requirement of escalation of medical care related to back pain by patients
Time frame · 12 months
Registry description
Proportion of patients requiring escalation of medical care related to back pain (e.g. spine surgery, injections into IVD, or Emergency Department visits related to debilitating back pain) will be assessed by percentages per arm
