Study Description
Brief Summary:

RATIONALE: Captopril is a drug that may be able to decrease side effects caused by radiation therapy, and may improve the quality of life of patients with non-small cell lung cancer or limited-stage small cell lung cancer.

PURPOSE: This randomized phase II trial is studying how well captopril works in decreasing side effects and improving the quality of life in patients who have received radiation therapy with or without chemotherapy for stage I, stage II, or stage IIIB non-small cell lung cancer or limited-stage small cell lung cancer.

Condition or disease Intervention/treatment Phase
Lung Cancer Pulmonary Complications Radiation Fibrosis Drug: captopril Phase 2

Detailed Description:


  • Determine the effect of captopril on the incidence of pulmonary damage at 12 months after radiotherapy with or without chemotherapy in patients with stage II-IIIB non-small cell lung cancer, stage I central non-small cell lung cancer, or limited stage small cell lung cancer.
  • Compare the quality of life of patients treated with captopril vs patients who undergo post-radiotherapy observation only.
  • Determine the persistence of captopril's effect on pulmonary toxicity in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, total lung irradiated (< 25% vs 25-37% vs more than 37%), prior surgery (yes vs no), and prior chemotherapy (yes vs no). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral captopril 3 times daily for 1 year in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients undergo observation only for 1 year. Quality of life is assessed at baseline and at months 3, 6, 12, and 18.

Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 205 patients will be accrued for this study within 18 months.
