• Subjects agree to maintain a stable medication regimen in the absence of a disease flare
• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
• carbon dioxide partial pressure < 45 mm Hg, room air oxyhemoglobin saturation > 85%
• A willingness to participate in all portions of the protocol, including serial bronchoscopy, requisite surveillances, and ancillary immunologic studies in follow-up visits at this institution
• For woman of childbearing age, a negative pregnancy test, and a willingness to use two methods of contraception, or abstinence

• Evidence for an opportunistic infection/colonization of the airways, i.e., non-bacterial
• Evidence for systemic illness including hematologic disorders (defined by an absolute neutrophil count (ANC) < 4000 /mL and platelets < 120,000/mL), cirrhosis, or hepatic insufficiency (total bilirubin, or alkaline phosphatase > 1.5 x normal, serum glutamate oxaloacetate transaminase, or serum glutamate pyruvate transaminase > 1.2 x normal values), or a coagulopathy (INR > 1.4), seizure disorder
• Evidence for renal insufficiency with a calculated creatinine clearance using the Cockcroft and Gault's method of < 80 ml/min for males and < 70 ml/min for females, or serum creatinine > 1.4 mg/dL.
• Evidence of coronary artery disease by history, e.g., angina or history of myocardial infarction within the past 12 months, unless corrected by coronary artery bypass graft within < 5 years, and asymptomatic since
• Evidence for systemic abnormal renal function manifested by uncontrolled hypertension (systolic blood pressure > 160 mmHg or diastolic blood pressure >90 mmHg), hyperkalemia (serum potassium > 5.0 meq/dl, and/or elevated serum potassium above the normal range for the subject's age)
• Pregnancy or lactation, or inability to take contraception during and for 6 months following treatment

• Known hypersensitivity or allergy to cyclosporine
• Concurrent participation in other clinical trials within the prior month
• Known medical or psychological condition (severe personality disorder or mental illness) that would not permit the subject to complete the trial or sign informed consent
