About this trial
In this double-blind phase II randomized controlled trial, patients with lung cancer or ≤2 oligometastatic pulmonary lesions and a concomitant diagnosis of ILD who are planned for radical Radiation Therapy (RT) will be randomized using a 2 x 2 factorial design to oral N-acetylcysteine (NAC) versus placebo, and also to short course corticosteroids versus placebo.
Eligibility criteria
Qualifiers
Lung cancer or 1-2 oligometastatic pulmonary lesions planned for radical intent radiotherapy [minimal Biologically Effective Does (BED) of 48 Gy10 (Gray) or biological equivalent].
Pathologically (histologically or cytologically) proven diagnosis of cancer is not required, but strongly recommended.
If the risk of biopsy is unacceptable, pathologic confirmation is not required providing there is growth over time on Computed Tomography (CT) imaging and/or Fluorodeoxyglucose (FDG) avidity that is strongly suggestive of malignancy.
Fibrotic Interstitial Lung Disease (ILD) of any subtype, as diagnosed by a respirologist and confirmed by central review
Disqualifiers
Prior lung radiotherapy
Current use of oral or intravenous corticosteroids
Plans for the patient to receive other local therapy to the target lesion(s) while on this study, except at disease progression
Any medical condition that could, in the opinion of the investigator, preclude radiotherapy or prevent follow-up after radiotherapy
