Belumosudil to Block Chronic Lung Allograft Dysfunction (CLAD) in High Risk Lung Transplant Recipients
(CLAD)
What this study is about
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).
View original scientific description
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).
Interventions
DRUG
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.
DRUG
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.
Primary outcome measures
Time from randomization to the first occurrence of probable or definite CLAD (per ISHLT 2019 standard defined criteria), lung retransplant, or death
Time frame: From randomization until study completion - scheduled assessments: minimum of 1 year, maximum of 3 years
Probable CLAD is defined as a \>= 20% decline in Forced Expiratory Volume in 1 Second (FEV1) compared to the baseline value on 2 measurements taken at least 3 weeks apart and after exclusion or adequate treatment of potential secondary causes of allograft dysfunction. The baseline FEV1 value is defined as the average of the 2 best posttransplant FEV1s taken at least 3 weeks apart
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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. 2. Single or bilateral lung transplant recipient age ≥ 12 years 3. 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 4. 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 purp

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
