Liposomal Cyclosporine A for Bronchiolitis Obliterans Syndrome (BOSTON-1 Trial)

Phase 3
Waitlist Available
Research Sponsored by Zambon SpA
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Patients should be on a maintenance regimen of immunosuppressive agents including tacrolimus, a second agent such as but not limited to MMF or azathioprine, and a systemic corticosteroid such as prednisone as third agent. The regimen must be stable within 4 weeks prior to randomization with respect to the therapeutic agents
Patients have no concomitant diagnoses that are considered fatal within one year (12 months) of Screening
Must not have
Patients with confirmed other causes for loss of lung function, such as acute infection, acute rejection, restrictive allograft syndrome (CLAD - RAS phenotype, see Protocol Specific Definition)
Patients with liver disease and serum bilirubin > 3-fold upper limit of normal range or transaminases > 2.5 upper limit of normal range
Timeline
Screening 3 weeks
Treatment Varies
Follow Up baseline through study completion (52 weeks)

Summary

This trial is testing whether adding a certain medication to the usual care for people with BOS may help improve symptoms.

Who is the study for?
This trial is for adults over 18 who had a single lung transplant at least a year ago and are diagnosed with Bronchiolitis Obliterans Syndrome (BOS). They must have stable immunosuppressive therapy, understand the study, consent to data retrieval, not be pregnant or breastfeeding, use contraception if applicable, and not have any life-threatening conditions expected within a year.
What is being tested?
The trial tests aerosolized liposomal cyclosporine A added to standard care versus standard care alone in treating BOS after lung transplantation. The goal is to see if this new treatment improves lung function and patient outcomes compared to usual treatments.
What are the potential side effects?
Potential side effects of liposomal cyclosporine A may include respiratory issues due to inhalation therapy, immune system suppression leading to increased infection risk, possible kidney problems as seen with other forms of cyclosporine A, and general drug sensitivity reactions.
