Official title
A Phase II Trial of Hypofractionated Radiotherapy in Patients With Limited Progression on Immune Checkpoint Blockade
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Drugs called checkpoint inhibitors help the immune system fight cancer. When the effectiveness of these drugs wears off, it may be possible to renew their effectiveness by combining it with a special type of radiation therapy called stereotactic body radiation therapy (SBRT). SBRT is a commonly used type of radiation therapy that gives high dose radiation with high precision to tumors in 1-5 treatments. Radiation therapy, such as SBRT can also treat sites of metastases. The use of checkpoint inhibitors in combination with SBRT has been suggested to improve the immune response against cancer but has not been tested in a formal clinical trial. Up to three lesions can be treated with SBRT. This study only allows checkpoint inhibitors that are already approved by the Federal Drug Agency (FDA) for the treatment of your disease. All radiation therapy will be done on machines which are FDA approved.
