Официальное название

Belumosudil to Block Chronic Lung Allograft Dysfunction (CLAD) in High Risk Lung Transplant Recipients: A Randomized, Multicenter, Double Blind, Placebo-Controlled Trial (CTOT-47)

Обзор

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.

Вмешательства

Препарат Belumosudil
Participants will receive Belumosudil 200 mg daily (increased to 200 mg twice daily in participants receiving concurrent strong CYP3A inducers or PPIs) + maintenance IS for a duration of one year from randomization.
Препарат Placebo for Belumosudil
Participants will receive Placebo for Belumosudil 200 mg daily (increased to 200 mg twice daily in participants receiving concurrent strong CYP3A inducers or PPIs) + maintenance IS for a duration of one year from randomization.

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
Cytomegalovirus (CMV) polymerase chain reaction (PCR) negative within 30 days of enrollment
In the absence of contraindications, must have received adult vaccinations or documented immunity as outlined in current National Institute of Allergy and Infectious Diseases (NIAID) Division of Allergy, Immunology, and Transplantation (DAIT) Guidance for Patients in Transplant Trials

Diagnosed with probable or definite CLAD according to International Society for Heart and Lung Transplantation (ISHLT) guidelines prior to enrollment.
Posttransplant treatment with anti-thymocyte globulin within 30 days or alemtuzumab or any other prohibited medication within 90 days prior to enrollment.
Epstein-Barr virus (EBV) seronegative recipient who received EBV positive donor lung(s).
Treatment with any other investigational pharmacologic agent within 30 days prior to enrollment.
Significant active uncontrolled infection which, in the opinion of the investigator, would place the participant at increased risk.
Current use of sirolimus or everolimus.
Recipient human immunodeficiency virus (HIV) positive.
Recipient Hepatitis B surface antigen positive or Hepatitis B core antibody positive.
Received lung(s) from a donor with known Hepatitis B virus (HBV) including Hepatitis B core antibody positive donors.
Recipient history of Hepatitis C, Hepatitis C seropositive, or received lung(s) from a donor with known Hepatitis C (participants who have 3 months of documented consecutive undetected Hepatitis C virus PCR after treatment or spontaneous clearance will not be excluded).
History of clinically significant surgical factors (such as phrenic nerve damage, transplant lung resection, chest wall surgery), or mechanical factors (such as posttransplant airways disease including bronchial dehiscence, stenosis, dilation, or stent placement, pleural disease) that impedes lung function.
