Official title
Phase I Study of Reirradiation With NBTXR3 for Inoperable Locoregional Recurrent Non-Small Cell Lung Cancer (NSCLC)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I trial investigates the best dose and side effects of NBTXR3 when given together with radiation therapy for the treatment of non-small cell lung cancer that cannot be treated by surgery (inoperable) and has come back (recurrent). NBTXR3 is a radio-enhancer designed to increase the radiotherapy energy dose deposition inside tumor cells. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving NBTXR3 and radiation therapy may increase radiation-dependent tumor cell killing without increasing the radiation exposure of healthy surrounding tissues.
