Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Changes in Mean Cortical Thickness
The primary outcome measure is the percent change in mean cortical thickness (C.Th) of bones receiving 30 Gy or more at 3 months post SBRT, when compared to pre-SBRT cortical thickness
At baseline and at 3 months post radiation
Secondary Outcomes (4)
4 Time Points Assessing Change in Mean Cortical Thickness of Bones
At baseline, 3 months, 6 months, 9 months and 12 months post radiation
Number of Participants With Chest Wall Pain
At baseline, 3 months, 6 months, 9 months and 12 months post radiation
Number of Participants With Rib and Vertebral Fracture
At 12 months post radiation
Urine Concentration at 4 Time Points
At 3 months, 6 months, 9 months and 12 months post radiation

Eligibility Criteria
You may qualify if:
- Patients must have a peripheral lung tumor that is amenable to SBRT as determined by the treating radiation oncologist. To be classified as a peripheral lung tumor, the tumor edge (the edge of the gross tumor volume or GTV in radiation treatment planning software) must be within 2 cm of the chest wall. This is determined by the treating radiation oncologist. The chest wall is defined as the chest wall musculature or ribs/vertebrae immediately adjacent to the lungs.
- Patients must have ECOG status of 0-3
- Patients must have a life expectancy of at least 3 months as determined by the treating radiation oncologist.
- Patients must have the ability to understand and the willingness to sign an IRB-approved informed consent document.
You may not qualify if:
- Tumor edge is greater than 2 cm from the chest wall. The edge of tumor is the edge of the gross tumor volume or GTV as defined in radiation treatment planning software. This is determined by the treating radiation oncologist.
- Tumors that are expected to require more than 10 fractions of radiation as determined by the treating radiation oncologist.
- History of using bone anti-resorptive agents including bisphosphonates or RANK-L inhibitors within the last 1 year.
- Inability to stand or sit upright for at least 30 minutes, which is necessary for ingestion of risedronate.
- Hypocalcemia defined as serum total calcium lower than 8.5 mg/dL on most recent bloodwork that is within 3 months of administration of study drug/placebo.
- Severe renal impairment (EGFR \<30 mL/min) on most recent bloodwork that is within 3 months of administration of study drug/placebo.
- Known allergy to risedronate or other bisphosphonates
- Surgery affecting the bone or dental operations within the last 6 months. This will be explicitly asked and documented in the EMR by treating radiation oncologist.
- Dental operations do not include routine cleaning or cavity fillings
- Dental operations that exclude patients refer to any manipulation of mandible.
- Positive urine pregnancy test in women of child bearing potential within 1 week of registration. Pregnant women are excluded from this study because radiation has clear teratogenic and potentially abortifacient risks.
