This technology features a method for preventing or treating radiation-associated loss of bone mass, bone density, or bone strength in a subject. This technology involves administering to the subject an amount of anti-resorptive or osteoclast-inhibiting compound sufficient to prevent or mitigate loss of bone mass, density, or strength caused by radiation-associated increases in the number or activity of osteoclasts.

Existing antiresorptive therapies (bisphosphonates: alendronate/Fosamax, risedronate/Actonel, ibandronate/Boniva, zoledronate/Zometa/Reclast, and pamidronate/Aredia; and anti-RANKL: denosumab/Prolia/Xgeva) for osteoporosis are effective through the inhibition of osteoclastic bone resorption. Data indicate that exposure to ionizing radiation causes a very rapid and profound activation of osteoclasts, to the degree that treatment will likely become necessary once the problem (rapid bone loss) is fully identified.
