Detailed Description

Radiation pneumonitis (RP) is the most common and main dose-limiting toxicity after thoracic RT. RP is characterized histologically by diffuse alveolar damage and acute vascular permeability induced b...

Eligibility Criteria

Inclusion

  • 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
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-3
  • Age ≥ 18
  • Life expectancy \> 6 months
  • Patients are allowed to receive anti-fibrotic agents used in the treatment of Idiopathic Pulmonary Fibrosis (IPF) or non-IPF fibrotic ILD (e.g. nintedanib, pirfenidone) and/or corticosteroids, if those are part of their current ILD treatment regimen. Other immunosuppressive drugs such as mycophenolate, azathioprine, cyclophosphamide, and rituximab must be stopped for 2 weeks prior and 2 weeks after Radiation Therapy (RT).
  • Concurrent standard chemotherapy is allowed where indicated. All other systemic therapies, including biologic targeted agents or immunotherapy, or any drugs with known radiosensitive effects, must be stopped for 2 weeks prior and 2 weeks after treatment.

Exclusion

  • 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
  • Pregnancy
  • If not pregnant, use of effective contraception methods for women of childbearing age is required which can include:
  • hormonal methods (e.g. oral, injected, implanted),
  • placement of an intrauterine device,
  • barrier methods (i.e. condoms),
  • sterilization of the partner (e.g. previous vasectomy)
  • abstinence
  • Women who become pregnant should stop taking NAC and/or dexamethasone and inform their study doctor.
  • Male participants should use adequate forms of birth control with their partners.
  • Currently breastfeeding
  • Current or recent use of NAC
  • Contraindications to dexamethasone or N-Acetyl Cysteine (NAC). These include:
  • Previous intolerance or allergy to dexamethasone or NAC
  • Scleroderma
  • Active infection
  • Glaucoma
  • Psychiatric disorder that could be exacerbated by dexamethasone
  • Cystinuria
  • Any other condition that the treating physician believes to be a contraindication to dexamethasone or NAC
