Studying the Treatment Effect of Pirfenidone in Chronic Lung Allograft Dysfunction (STOP-CLAD)

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Disorder Related to Lung Transplantation, Chronic Lung Allograft Dysfunction

In brief

Greater than 50% of lung transplant recipients show signs of chronic lung allograft dysfunction (CLAD) by 5 years post-transplantation.Therapies to prevent or slow CLAD are lacking. Anti-fibrotic therapies may offer an avenue to prevent progression of CLAD and prolong allograft survival. This study investigates if Pirfenidone therapy will stabilize lung function decline and slow progression of Functional small airways disease (fSAD) in lung transplant recipients with CLAD.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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)

You may not qualify if…

• 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
