Pneumonitis Prevention Protocol Using Pentoxifylline and α-tocopherol In Stage III Non-Small Cell Lung Cancer Patients Undergoing Chemoradiation

This is a multi-centre, Phase II, double-blind, placebo-controlled randomized trial. Eligible participants will include newly diagnosed, inoperable Stage III patients with NSCLC who will be treated with radical intent concurrent chemoradiation therapy with planned consolidation immune checkpoint inhibitor (ICI) as per standard of care. Participants will be randomized in a 1:1 ratio between control arm (Placebos for 6 months) (Arm 1) and the experimental arm (Pentoxifylline/α-Tocopherol for 6 months) (Arm 2).
