European Trial of Pirfenidone in BOS A European Multi-center Study


Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Disorder Related to Lung Transplantation | CLAD | Bronchiolitis Obliterans
  • Age: Between 18 - 100 Years
  • Gender: Male or Female

Inclusion Criteria:

  • Patients >18 years of age
  • Azithromycin therapy for at least 4 weeks prior to study start, with an Azithromycin dose of minimum 250 mg/day at least 3 times per week as this is considered standard therapy for bronchiolitis obliterans syndrome.
  • Double lung transplantation is required.
  • Patients must be at least 6 months after transplantation and must have documented post-transplant baseline value of FEV1 (mean of the 2 highest values measured at least 3 weeks apart according to ISHLT criteria).
  • Patients must have BOS grade 1 to BOS grade 3.
  • Patients must have documented progressive disease as demonstrated by all of the following criteria:
  • Patients must have at least 3 FEV1-measurements in the last 6 months, each at least 3 weeks apart
  • a total decline of at least 200ml in FEV1 i
  • a decline of at least 50 ml in the last two measurements

Exclusion Criteria

  • Patients with lung redo transplantation, combined transplantation (including heart and lung transplantation) or single lung recipients.
  • Patients with any severe comorbidity complicating BOS which might determine the prognosis and functional level of the patient (e.g. invasive aspergillosis, active malignant disease) within the last 12 months.
  • FEV1 decline related to other non BOS causes (eg pneumothorax, bronchial stenosis, effusion, etc.)
  • Patients who have developed BOS grade 3.
  • Patients who on Thorax CT at entry demonstrate new significant findings which are not compatible with BOS like interstitial fibrosis, consolidation, appearances suggesting Restrictive Allograft Syndrome (RAS) and acute pulmonary infection as cause of decline in lung function.
  • Documented acute perivascular rejection higher than grade A1 or findings compatible with antibody mediated rejection
  • Pregnancy or lactation (women of childbearing capacity are required to have a negative serum pregnancy test before treatment and must agree to maintain highly effective contraception by practicing abstinence or by using at least two methods of birth control from the date of consent through the end of the study).
  • Renal insufficiency (Creatinine clearance <30 ml/min calculated by the CKD-Epi formula.
  • Any of the following liver test criteria above the specified limit:
  • Total bilirubin above the upper limit of the normal range (ULN), except in patients with predominantly unconjugated hyperbilirubinemia (e.g., Gilbert's syndrome)
  • Aspartate or alanine aminotransferase (AST or ALT) >3 ULN
  • Known allergy or hypersensitivity to Pirfenidone
  • Ongoing use or expected use of any of the following therapies:
  • Strong inhibitors of CYP1A2 (e.g. fluvoxamine or enoxacin)
  • Moderate inhibitors of CYP1A2 (e.g. mexiletine, thiabendazole, or phenylpropanolamine [Note: ciprofloxacin will be allowed only at doses 500 mg BID])
  • Previous treatment with Pirfenidone after transplantation
  • Patients who have resumed smoking after transplantation
