Official title

A Randomized Clinical Trial of Prophylactic Risedronate for Patients With Peripheral Lung Tumors Treated With SBRT

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a double blind randomized controlled study investigating the efficacy of a single dose of 150 mg risedronate (a bone anti-resorptive) vs a single dose of placebo given prior to SBRT for peripheral lung tumors that are within 2 cm of the chest wall. Our hypothesis is that the use of a single dose of 150 mg risedronate will eliminate or greatly reduce the rapid bone loss that occurs with radiation induced early osteoclast recruitment/activation. Patients will be given either a single dose of 150 mg risedronate or placebo at the time of their treatment mapping "simulation" CT scan. Typically, radiation treatments begin at 1 - 3 weeks following this mapping scan, as each treatment plan requires detailed physics calculations and quality assurance checks. All CT imaging referenced below is performed as a routine standard of care surveillance and is necessary for cancer treatment follow-up. These chest CT scans that are utilized in this research protocol would be performed every 3 months regardless of inclusion on this trial.
