Summary

The goal of this interventional phase III clinical trial is to evaluate objective intracranial response rate (iORR) after a treatment with total cranial radiation therapy plus concomitant transdermal nitroglycerin (NTG) addition or total cranial radiation therapy only in patients with stage IV non-small cell lung cancer with brain metastases and EGFR mutation. The main questions it aims to answer are:

Determine progression-free survival (PFS) to CNS and overall survival (OS). Evaluate and compare the quality of life (QoL) of patients during and after treatment.

Evaluate the cognitive function of patients before, during and after treatment. Evaluate treatment-associated toxicity to grade adverse treatment events Evaluation of HIF1α, VEGF and ROS1 in peripheral blood before and after nitroglycerin treatment.

All participants will have laboratory tests at the beginning and end of radiation therapy. Cranial MRI will be performed prior to treatment and 12 weeks after the end of treatment, then every 16 weeks until intracranial progression. Patients in the interventional group will be given 36 mg patches of transdermal nitroglycerin for 24 hours with a 12-hour rest interval during treatment with radiation therapy. The control group will only receive total cranial radiation therapy at the same doses and with the same schedule.

Nitroglycerin

Patients in the intervention group will receive four 8mg-patches (36 mg final dose) of transdermal nitroglycerin with 10 mg release in 24 hours, for 24 hours with 12-hour rest intervals (to avoid receptor saturation) during treatment with radiation therapy (30 Gy in 10 fractions, or 10 days of treatment).
