Condition(s) targeted: Disuse Osteoporosis
Intervention: Zoledronic acid (Drug)
Phase: Phase 4
Status: Completed

Summary
In subjects with acute SCI: To compare the effects of parenteral zoledronic acid therapy on
preservation of regional and total skeletal mass (DXA).
Hypothesis: Zoledronic acid will dramatically diminish bone loss in persons with acute SCI,
as evidenced by serial densitometry determinations (DXA).
Clinical Details
Official title: The Efficacy of Zoledronic Acid in the Prevention of Bone Loss in Acute Spinal Cord Injury
Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Bone Mineral Density (BMD) at the Distal Femur and Proximal Tibia at Baseline and Month 12.
Secondary outcome: Bone Mineral Density (BMD) at the Total Hip at Baseline and Month 12
Detailed description:
Immobilization is associated with disuse osteoporosis. Spinal cord injury (SCI) produces a
syndrome of acute skeletal immobilization with immediate and irreversible unloading of the
involved skeletal regions resulting in accelerated bone loss. In addition to rapid bone
loss, there are also the complications of hypercalciuria, hypercalcemia, nephrolithiasis,
and renal insufficiency. In some reports, as much as 50% of regional bone mass has been
lost within the first year after paralysis. A depletion of regional bone of such magnitude
greatly increases the risk of fractures, with associated morbidity and increased cost of
care. Often, these fractures occur with minimal or non-obvious trauma and may pass
undiagnosed for varying lengths of time due to the absence of pain sensation. The acute
complications of fracture may include hemorrhage, deep venous thrombosis, and autonomic
dysreflexia. Long-term complications include functional deformity, non-union, infection,
heterotopic calcification, and significantly longer healing time. The sociology-economic
consequences include a minimum of 1 to 2 weeks of hospitalization and the potential need for
an increased level of attendant care. This study will address the efficacy of a
bisphosphonate, zoledronic acid (Reclast: 5 mg; Novartis Pharmaceuticals Inc., East Hanover,
NJ), in the prevention of the bone loss associated with acute SCI.
Prevention of regional osteoporosis in persons with SCI would reduce the morbidity
associated with fractures, a known secondary complication of immobilization. Thus, the
quality of life would be improved in terms of employment responsibilities (reduction in days
absent from employment and income lost) and personal activities (recreational endeavors,
independence, and ease in which one performs activities of daily living). Individuals with
SCI may then engage more securely in activities without fear of fracture, a tremendous
psychological benefit.
