Belumosudil to Block Chronic Lung Allograft Dysfunction (CLAD) in High Risk Lung Transplant Recipients
United States234 participantsStarted 2025-03-12
Plain-language summary
The purpose of this study is to see if taking the study drug, Belumosudil, for 52 weeks in addition to your usual care and medication, will prevent Chronic Lung Allograft Dysfunction (CLAD) in participants who have a lung biopsy that shows evidence of rejection or inflammation to the transplanted lung(s). For this study, biopsies that show evidence of Acute Rejection (AR), Lymphocytic Bronchiolitis (LB), Organizing Pneumonia (OP) or Acute Lung Injury (ALI) are referred to as "Qualifying Biopsies"; patients who had evidence of one or more of these conditions on a recent biopsy are eligible for enrollment in this study. Belumosudil is an investigational drug that blocks a molecule in the body that reduces inflammation and scarring and may play a role in the development and progression of CLAD. Belumosudil is a drug approved by the FDA to treat adults and children 12 years and older with chronic graft-versus-host disease (cGVHD), a condition with some similarities to CLAD.
The primary objective it to determine the efficacy of treatment with Belumosudil + maintenance immunosuppression (IS) versus placebo + maintenance IS on preventing the subsequent development of probable or definite CLAD, lung retransplant, or death.

Inclusion criteria
✓. Participant and/or parent or guardian must be able to understand the purpose of the study, willing to participate, sign the informed consent, and if applicable assent.
✓. Single or bilateral lung transplant recipient age ≥ 12 years
✓. A qualifying biopsy obtained 60 to 550 days after lung transplant with evidence of allograft injury histology; a qualifying biopsy must have one or more of the following features alone or in combination: Acute Rejection (AR), Lymphocytic Bronchiolitis (LB), Organizing Pneumonia (OP), or Acute Lung Injury (ALI). The presence of any grade AR (A1 or greater) or LB (B1 or greater) qualifies for inclusion
✓. Females of reproductive potential and males with female partners of reproductive potential must agree to use effective contraception during treatment with belumosudil or placebo and for at least 3 months after the last dose. Participants must agree to refrain from donating or cryopreserving sperm, eggs (ova or ovocytes) for the purpose of reproduction during treatment with belumosudil or placebo and for at least 3 months after the last dose.
✓. Meeting hematologic laboratory criteria: absolute neutrophil count (ANC) \>= 0.5 x 10(9)/L and platelet count \>= 50 x 10(9)/L within 30 days of enrollment
✓. Meeting all blood chemistry laboratory criteria: aspartate aminotransferase (AST) or alanine transaminase (ALT) \< 2x upper limit of normal (ULN), bilirubin \< 1.5x ULN unless due to Gilbert's syndrome, estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73m2 within 30 days of enrollment
