Study Description

Thoracic radiation therapy combined with chemotherapy (with or without immunotherapy) is the cornerstone of management in patients with locally advanced non-small cell lung cancer (NSCLC). Despite advancement in radiation delivery techniques, about 1/3 of patients who undergo thoracic radiation therapy (TRT) for advanced NSCLC suffer from symptoms of radiation-induced inflammation of the esophagus, also known as radiation-induced esophagitis (RE). Radiation induced esophagitis can have detrimental effect on quality-of-life and can result in unplanned treatment interruptions. If not treated appropriately, acute severe radiation induced esophagitis might also progress to long-term consequences such as esophageal stricture. Existing management of radiation induced esophagitis entails addressing the symptoms and nutritional needs. Anecdotal reports have shown improvement in radiation induced esophagitis symptoms with proton pump inhibitors (PPI); however, no robust prospective evidence exists to support use of PPI to manage radiation induced esophagitis to mitigate detrimental impact on QoL. Recent studies have shown that the PPI esomeprazole has antioxidant, anti-inflammatory and antifibrotic properties; and it potentiates the effect of ionizing radiation on cancer cells.

The investigators hypothesize that the use of esomeprazole will reduce the frequency of symptomatic (grade ≥2) radiation induced esophagitis compared to reported rates in literature. To address this hypothesis, the investigators propose a phase II study with locally advanced non-small cell lung cancer (NSCLC) patients with the following objectives: The primary objective is to evaluate the frequency of acute symptomatic RE and associated patient-reported symptoms with use of 40 mg of esomeprazole (two pills of 20 mg strength of esomeprazole) once daily for the duration of TRT and for two weeks after completion of TRT. Finally, as exploratory objectives, the investigators plan to identify orthogonal biomarkers that predict radiation induced esophagitis (RE) in the context of using esomeprazole.

The frequency of symptomatic radiation induced esophagitis at 2 weeks after RT completion and at 3 months from the start of TRT will be documented in a cohort of patients with locally advanced NSCLC receiving TRT (EQD2 of 45 Gy or higher with concomitant chemotherapy and estimated esophageal maximum dose of 30 Gy or higher). Both clinician-reported metrics (Common Terminology Criteria for Adverse Events version 5.0) and patient-reported metrics (Patient-Reported Outcomes version of the CTCAE [PRO-CTCAE]) will be used.

As part of exploratory objectives, investigators will investigate correlative biomarkers that could predict radiation-induced esophagitis in the context of using esomeprazole.

This work is significant as it will provide important evidence to support the use of esomeprazole, a readily available over-the-counter medication with thoracic radiation therapy to reduce the frequency of symptomatic radiation induced esophagitis given the lack of clinical evidence in the existing literature supporting this premise.
