Description
Inclusion Criteria:
- Lung transplant recipients 18 years of age or older
- Greater than 6 months after single or bilateral lung transplantation
- Baseline FEV1 and FVC values (mean of two highest value measured 3 weeks apart) > 50% predicted (to assure viable graft)
- Diagnosis of CLAD (two consecutive spirometric values of FEV1 alone or both FEV1 and FVC < 80% of baseline)
Exclusion Criteria
- Acute Rejection (AR) diagnosis by biopsy in the 28 days prior to enrollment
- Treatment with pulse steroids, Anti-thymocyte Globulin (ATG), extracorporeal photopheresis (ECP), plasmapheresis, or Immunoglobulin therapy aimed at CLAD within the 28 days prior to enrollment
- If the subject is receiving chronic Azithromycin therapy, the dose must be stable for the 28 days prior to enrollment
- Presence of active pulmonary infection at the time of enrollment as determined by an investigator in consultation with the treating pulmonologist
- Diagnosis of bronchial stenosis either a) requiring stenting, or b) thought to be responsible for the spirometric decline by principal investigator
- Abnormal liver function tests (aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 2 x upper limit of normal (ULN), Alkaline phosphatase > 2.5 x ULN, total bilirubin > ULN) or known cirrhosis (>2 times upper limit of normal of AST/ALT/AP)
- Total white blood cell (WBC) < 3.0 K/uL
- Moderate to Severe Renal insufficiency (CrCl <15 mL/min calculated by the Cockcroft-Gault equation)
- Use of any medication known to cause significant interactions with pirfenidone (strong CYP1A2 inhibitors such as Fluvoxamine or Enoxacin or inducers)
- Pregnancy or lactation. Women of child-bearing potential will have a pregnancy test at enrollment and must agree to maintain highly effective contraception with two methods of birth control from the date of consent through the end of the study.
- Tobacco use within 6 months
- History of alcohol abuse in the past 1 year as determined by the treating pulmonologist
- Any condition other than CLAD that will likely result in death in the next 1 year
- Any condition in the judgement of the principal investigator that would preclude participation in this study
- EKG with QTc interval > 500 msec at screening
- Listed for repeat lung transplantation

Change in Percent of Functional Small Airways Disease (fSAD) as Measured by Parametric Response Mapping
Time Frame: Baseline, 24 weeks
|
Evaluate if pirfenidone compared to placebo will stabilize progression of fSAD by comparison of inspiratory and expiratory high resolution computed tomography (HRCT) images through co-registration to provide quantitative measures of fSAD.
