Inhaled drug aims to save transplanted lungs from silent threat
NCT ID NCT04039347
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an inhaled form of cyclosporine A (L-CsA) added to standard care for lung transplant patients with bronchiolitis obliterans syndrome (BOS), a condition that scars the lungs' small airways. The goal was to see if the treatment could slow the decline in lung function over 24 to 48 weeks. The trial included 164 patients who had already completed earlier studies, but it was terminated early, so results are limited.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients who have completed all visits through the End of Treatment Visit in either BOSTON-1 or BOSTON-2, did not withdraw informed consent, and did not prematurely terminate study drug administration. 2. Patients should be on a three-drug maintenance regimen of immunosuppressive agents including tacrolimus or another CNI, a second agent such as but not limited to MMF or azathioprine, and a systemic corticosteroid such as prednisone. 3. Patients capable of understanding the purposes and risks of the clinical trial, who have given written informed consent and agree to comply with the clinical trial requirements/visit schedules, and who are capable of aerosol inhalation. 4. Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to Visit 1 and must agree to use one of the methods of contraception listed in Appendix II through their End of Study Visit. Exclusion Criteria: 1. Known hypersensitivity to L-CsA or to cyclosporine A. 2. Patients who experienced an AE related to study drug that led to permanent study drug discontinuation in BOSTON-1 or BOSTON-2. 3. Patients with new onset of malignancy while participating in BOSTON-1 or BOSTON-2, including post-transplant lymphoproliferative disorder, with the exception of treated, localized basal and squamous cell carcinomas. 4. Pregnant women or women who are unwilling to use appropriate birth control to avoid pregnancy through their End of Study Visit. 5. Women who are currently breastfeeding. 6. Receipt of an investigational drug, other than L-CsA, as part of a clinical trial within 4 weeks prior to Visit 1. This is defined as any treatment that is implemented under an Investigational New Drug (IND) or compassionate use. 7. Patients who are currently participating in an interventional clinical trial, other than BOSTON-1 or BOSTON-2. 8. Psychiatric disorders or altered mental status precluding understanding of the informed consent process and/or completion of the necessary procedures. 9. Any co-existing medical condition that in the Investigator's judgment will substantially increase the risk associated with the patient's participation in the clinical trial.
