This phase I/II trial tests the safety, side effects and best dose of NBTXR3 with radiation therapy (RT) and how well the combination works in treating patients with stage I-III non-small cell lung cancer (NSCLC). NBTXR3, a radio-enhancer, is a drug that, when activated by RT, is designed to increase the radiotherapy energy dose and may cause targeted destruction of tumor cells. RT uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Intensity-modulated radiation therapy (IMRT) is a type of 3 dimensional RT that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of RT reduces the damage to healthy tissue near the tumor. Giving NBTXR3 with IMRT may be safe, tolerable and/or effective in treating patients with stage I-III NSCLC.

PRIMARY OBJECTIVES:
I. To evaluate the feasibility and safety of radiation therapy with hafnium oxide-containing nanoparticles NBTXR3 (NBTXR3) in locally-advanced (LA)-NSCLC with the following dose escalation:
Ia. 45 Gy in 15 fractions (fx) with NBTXR3 at 22% recommended phase 2 dose (RP2D);
Ib. 52.5 Gy in 15 fx with NBTXR3 at 22% RP2D;
Ic. 60 Gy in 15 fx with NBTXR3 at 22% RP2D;
Id. 60 Gy in 15 fx with NBTXR3 at 33% RP2D. (Phase I)
II. To estimate the efficacy of radiation therapy alone with NBTXR3 in inoperable, locoregional NSCLC. (Phase II Dose Expansion)
III. To evaluate the safety of RP2D. (Phase II Dose Expansion)
SECONDARY OBJECTIVES:
I. To evaluate the anti-tumor response of radiation with NBTXR3 in patients with inoperable, locoregional NSCLC. (Phase II Dose Expansion)
II. To evaluate time-to-event outcomes for radiation therapy with NBTXR3 in patients with inoperable, locoregional NSCLC. (Phase II Dose Expansion)
EXPLORATORY OBJECTIVE:
I. To assess biomarkers of response in patients treated with NBTXR3/RT. (Phase II Dose Expansion)
OUTLINE: This is a phase I dose-escalation study of NBTXR3 and radiation therapy followed by a phase II dose-expansion study.
Patients receive NBTXR3 intratumorally via endobronchial ultrasound bronchoscopy (EBUS)-guided, cone beam computed tomography (CBCT)-guided bronchoscopic, or computed tomography (CT)-guided injection on day 1. Starting within 14 days of NBTXR3 injection, patients undergo IMRT 5 days per week (Monday-Friday) for up to 15 fractions over 3-4 weeks. Additionally, patients undergo CT or positron emission tomography (PET)/CT, blood sample collection, and biopsy throughout the study.
After completion of study treatment, patients are followed up at 4 and 11-13 weeks after the last fraction of RT and then every 3 months for up to 2 years.
