简要总结

Currently, the standard of care treatment for newly diagnosed, inoperable stage III non-small cell lung cancer is radiotherapy (RT) with concurrent chemotherapy, followed by immune checkpoint inhibitors (ICI). RT is a highly effect local treatment. However, high doses of radiation used in curative settings can cause adverse side effects. The most common RT side effect in lung cancer is Radiation Induced Lung Injury (RILI), which can manifest as pneumonitis and/or pulmonary fibrosis. Lung injury can negatively impact patients' well-being and quality of life, and may lead to increased mortality. Risk of lung injury is particularly increased when patients are treated with a combination of treatments (i.e., RT, chemotherapy, and ICI). The drug Pentoxifylline (in combination with α-Tocopherol (Vitamin E)) has been shown to prevent/alter the progression of lung injury and there is a growing body of evidence to support the safety and efficacy of phosphodiesterase inhibitors in cancer treatment. The proposed study aims to determine if the addition of Pentoxifylline, given in combination with α-Tocopherol (Vitamin E), to standard of care treatment will reduce side effects related to lung injury and improve quality of life in this study population.

详细描述

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).

入选标准

  • •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.

排除标准

  • •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.
