Pneumonitis Prevention with Pentoxifylline and Vitamin E in Stage III NSCLC with Chemoradiation

Official title: Pneumonitis Prevention Protocol Using Pentoxifylline and α-tocopherol in Stage III Non-Small Cell Lung Cancer Patients Undergoing Chemoradiation

Run by University Health Network, Toronto · NCT06634056 · Data updated 2026-11-12

This trial tests whether adding pentoxifylline and vitamin E can help prevent radiation-induced lung injury in adults with stage III non-small cell lung cancer who are receiving chemoradiation and planned immune therapy.

Is this trial a fit for you?

Likely a good fit

Adults with histologically confirmed stage III NSCLC planned for concurrent chemoradiation and consolidation immunotherapy, ECOG 0-2, adequate liver and kidney function, and no contraindications to pentoxifylline or vitamin E.

Probably not a fit

Patients with contraindications to pentoxifylline or vitamin E, those not receiving the planned consolidation immunotherapy, or those with substantial comorbidity or limited life expectancy may not benefit.

What this trial studies

This is a multi-centre, Phase II, double-blind, placebo-controlled randomized trial. Eligible patients have newly diagnosed, inoperable stage III NSCLC and will receive radical-intent concurrent chemoradiation followed by consolidation immune checkpoint inhibitor therapy. Participants are randomized 1:1 to receive either pentoxifylline with α-tocopherol for six months or matched placebos. The study aims to see if the combination can reduce radiation-induced lung injury without adding safety concerns. Primary and secondary endpoints will assess lung injury incidence and safety signals in the context of standard-of-care treatment.

Why it matters

Potential benefit: If successful, the intervention could reduce radiation-related lung injury and improve quality of life for patients receiving chemoradiation and immunotherapy.

How similar studies have gone: Previous evidence suggests phosphodiesterase inhibitors like pentoxifylline may modulate lung injury, but this specific combination concurrent with chemoradiation and immunotherapy is relatively novel and requires trial data for confirmation.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Female and/or male aged ≥ 18 years.
* Histologically confirmed diagnosis of stage III NSCLC, planned for treatment with concurrent chemoradiation and consolidation immune checkpoint inhibitor as per standard of care with no medical contraindications to therapy.
* Patients with ECOG performance status 0-2 within 4 weeks of randomization.
* Adequate liver function (no evidence of Child-Pugh class C disease or cirrhosis) as per blood work done within 30 days of registration.
* Adequate kidney function (Creatinine clearance \> 50 mL/min) as per blood work done within 30 days of registration.

Exclusion Criteria:

* Participation in another clinical study with an investigational product during the last 6 months prior to registration.
* Patients who will have surgery as part of curative treatment.
* Previous radiotherapy to intended treatment volumes in the thorax.
* Active pregnancy.
* Life expectancy of less than 12 months.
* Hypersensitivity to Pentoxifylline or other xanthines such as caffeine, theophylline and theobromine or tocopherol (vitamin E).
* Participant has a history of acute (within 3 months) myocardial infarction, coronary artery disease, or cardiac arrhythmias.
* Ongoing hemorrhage or major bleeding risk. Patients on antiplatelets agents and anticoagulants (Aspirin, Clopidogrel, Ticlopidine, Cilostazol, Dipyridamole, Heparin, Dalteparin, Enoxaparin and Warfarin) can be enrolled, but major bleeding events will be captured. Patients on Warfarin will need frequent monitoring of their coagulation time to adjust Warfarin dosage.
