Brief Summary:
The objective of the trial is to assess efficacy and safety of add-on aerosolized liposomal cyclosporine A (L-CsA) to Standard of Care (SoC) therapy as compared to SoC therapy alone in the treatment of Bronchiolitis obliterans syndrome (BOS) in single lung transplant recipients.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Bronchiolitis Obliterans Chronic Rejection of Lung Transplant Lung Transplant Rejection Lung Transplant; Complications Lung Transplant Failure and Rejection Chronic Lung Allograft Dysfunction | Drug: Liposomal Cyclosporine A Drug: standard of care | Phase 3 |
This is a Phase III randomized, controlled clinical trial of L-CsA for the treatment of bronchiolitis obliterans syndrome in adults diagnosed with BOS following single lung transplant. Patients will receive either L-CsA (5 mg) via the PARI Investigational eFlow® Device twice daily plus Standard of Care (SoC) treatment, or SoC alone, for a period of 48 weeks. All patients will be eligible to continue in an open-label extension trial of L-CsA following completion of BOSTON-1.
Regardless of treatment allocation, all patients will continue to receive their SoC regimen for maintenance of the lung allograft. Eligible patients for the clinical trial must have a tacrolimus-based triple-drug therapy in combination with mycophenolate mofetil or its equivalent and a corticosteroid.
A total of 11 visits will be performed during the clinical trial. After informed consent has been obtained, a Screening Visit will be carried out in order to check general eligibility for participation. At the Randomization Visit, inclusion and exclusion criteria will be re-checked and spirometry performed. During the 48-week treatment period, visits are scheduled every 4-8 weeks. If a patient has an event that meets one of the criteria for progression of BOS, he/she will return to the clinic at least 2-weeks later for an unscheduled visit to have spirometry and other procedures performed.

Experimental: L-CsA treatment plus SoC
Liposomal Cyclosporine A 5 mg twice daily for 48 weeks + Standard of Care Therapy
|
Drug: Liposomal Cyclosporine A
This formulation is developed for inhalation use and delivered via the PARI eFlow® Device, which is a new technology of nebulizing liquid drugs with a perforated vibrating membrane resulting in an aerosol with a low ballistic momentum and a high percentage of droplets in a respirable size range of 3-5 μm
Other Name: L-CsA |
|
Active Comparator: Control treatment
In this arm only the standard of care is administered. Standard of care is a maintenance regimen of immunosuppressive agents.
|
Drug: standard of care
Standard of Care Therapy. Eligible 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 receiving azithromycin for prophylaxis or treatment of BOS, must be on a stable regimen for a least 4-weeks prior to randomization and will continue to receive azithromycin during the trial as deemed appropriate by the investigator.

Primary Outcome Measures :
- Mean change in FEV1 (mL) from baseline to Week 48 [ Time Frame: Baseline to Week 48 ]
Secondary Outcome Measures :
- Mean change in FEV1/FVC from baseline to Week 48 [ Time Frame: Baseline to Week 48 ]
- Time to Progression of BOS [ Time Frame: From date of randomization until the date of first documented progression of BOS, or date of retransplantation, or date of death from respiratory failure, whichever came first, assessed up to 52 weeks. ]
defined as the earliest of the following:
- Absolute decrease from baseline in FEV1 >/= 10% or >/= 200 mL and absolute decrease in FEV1/FVC of > 5% OR
- Change in BOS Severity, OR
- Re-transplantation, OR
- Death from respiratory failure This endpoint will be assessed in a combined analysis with a similar Phase III clinical trial, BT - L-CsA - 302 - DLT (BOSTON-2) which will be conducted in the same investigational centers in patients who have undergone double-lung transplantations.
Other Outcome Measures:
- Adverse Events [ Time Frame: Baseline through study completion (52 weeks) ]
- Acute tolerability of L-CsA [ Time Frame: Baseline through Week 48 ]change in forced expiratory volume in one second (FEV1); reports of cough or shortness of breath
- Hematology and Serum Chemistry Parameters [ Time Frame: From date of randomization until end of study participation (52 weeks) ]Number of patients with treatment-related changes in hematology or serum chemistry parameters assessed by CTCAE v5.0.

| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Criteria
Inclusion Criteria:
- Adult patients ≥ 18 years who received a single lung transplant at least 12 months prior to Screening.
-
Patients with BOS diagnosis defined as CLAD-BOS phenotype with:
- Screening FEV1 between 85-51% of personal best FEV1 value post-transplant OR
- Screening FEV1 >85% of personal best FEV1 associated with EITHER a ≥ 200 mL decrease in FEV1 in the previous 12 months OR according to medical history showing BOS progression.
-
Diagnosis of CLAD-BOS must be made at least 12 months after lung transplantation and
- within 12 months prior to the screening visit OR
- more than 12 months from screening and patient must have shown a decline in FEV1 ≥ 200ml in the previous 12 months before screening, which is not due to acute infection or acute organ rejection.

- 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.
