Study summary

This double-blind, randomized, placebo-controlled, multinational, multicenter, parallel-group, Phase 3, 2-arm, study will investigate the efficacy and safety of belumosudil compared with placebo, both administered on top of azithromycin and standard-of-care regimen of immunosuppression in male or female participants at least 1 year after bilateral lung transplant, who are at least 18 years of age and who have evidence of progressive CLAD despite azithromycin therapy.

Study details include:

The study duration will be up to 31 weeks for participants not entering the open-label extension (OLE) period and up to 57 weeks for participants entering the OLE period but not the long-term OLE.

The treatment duration will be up to 26 weeks for participants not entering the OLE period and up to 52 weeks for participants entering the OLE period but not the long-term OLE.

The number of visits will be up to 10 visits for participants not entering the OLE period and up to 16 visits for participants entering the OLE period but not the long-term OLE.

For participants who enter the long-term OLE, treatment and study participation will continue with visits every 12 weeks per protocol specifications.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participant ≥1 year post bilateral lung transplantation at the time of screening
  • Participants presenting with CLAD Stage 1 or 2: from >50% to 80% of post-transplant baseline at screening and at randomization
  • Participants who have received at least 8 weeks of azithromycin (≥250 mg/day, at least 3 times a week) prior to randomization

Exclusion criteria

Exclusion Criteria:

  • ≤50% of the post-transplant baseline value (CLAD 3 and 4)
  • Lung function decline that can be explained by non-CLAD causes including but not limited to acute lung allograft rejection (>A1), antibody-mediated rejection, airway stenosis, or tracheobronchomalacia

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
