Montelukast in Bronchiolitis Obliterans Syndrome (MLK002)

Brief Summary:
Chronic rejection (or Bronchiolitis Obliterans syndrome-BOS) is a major cause of mortality and morbidity after lung transplantation. Because montelukast has been shown to be of some efficacy in a similar disease (Obliterative Bronchiolitis after bone marrow transplantation), the investigators would like to test if montelukast can indeed slow down the progression of chronic rejection after lung transplantation.

Condition or disease Intervention/treatment Phase
Bronchiolitis Obliterans Lung Transplantation Graft Rejection Drug: Montelukast Phase 4

Detailed Description:
  • Prospective, interventional, randomized, double-blind, placebo-controlled trial.
  • Clinical setting (tertiary University Hospital).
  • Investigator-driven, no pharmaceutical sponsor.
  • Lung transplant recipients.
  • Add-on of study-drug (placebo or montelukast) to 'standard of care'
  • 1:1 inclusion ratio (placebo:montelukast).
  • Randomisation at diagnosis of chronic rejection after informed consent.

Drug Information available for: Montelukast

Arm Intervention/treatment
Experimental: montelukast sodium
Daily treatment with 10 mg montelukast after diagnosis of fibroproliferative BOS (fBOS) which is the low neutrophilic phenotype within BOS
Drug: Montelukast
After diagnosis of fBOS every day an oral capsule with 10 mg montelukast of placebo
Other Name: Montelukast TEVA

Placebo Comparator: placebo
Lactose monohydricum Ph.Eur.
Drug: Montelukast
After diagnosis of fBOS every day an oral capsule with 10 mg montelukast of placebo
Other Name: Montelukast TEVA

Primary Outcome Measures :
  1. survival/retransplantation rate after diagnosis of BOS [ Time Frame: 1 year after diagnosis ]
  2. survival/retransplantation rate at 2 years after diagnosis [ Time Frame: 2 years after diagnosis ]

Secondary Outcome Measures :
  1. Obstructive and restrictive pulmonary function evolution [ Time Frame: during 1 and 2 years of treatment ]
  2. Bronchoalveolar lavage fluid (BAL) [ Time Frame: during 1 and 2 years of treatment ]
    BAL will be used to assess cellularity, protein and mRNA concentration and microbiology

  3. peripheral blood [ Time Frame: during 1 and 2 years of treatment ]
    peripheral blood will be used to assess C-reactive protein, protein and mRNA concentration and fibrocytes content

  4. Cytomegalovirus (CMV) and non-CMV infection rates [ Time Frame: during 1 and 2 years of follow up ]
  5. Acute rejection and lymphocytic bronchiolitis rates [ Time Frame: after 1 and 2 years of treatment ]
