The objective of the trial is to assess the long-term safety and efficacy of L-CsA plus Standard of Care (SoC) in the treatment of BOS in single (SLT) and double lung transplant (DLT) recipients.
This is a Phase III, multicenter, open-label, extension clinical trial of L-CsA for the treatment of BOS.
Enrollment will be limited to patients who have completed 48 weeks participation in either the BT-L-CsA-301-SLT (BOSTON-1) or BT-L-CsA-302-DLT (BOSTON-2) trial. All patients in this clinical trial will receive L-CsA in addition to SoC, regardless of the randomization arm in prior trials.
IMP will be administered by BID inhalation (morning/evening) using the L-CsA eFlow. Patients who did not receive L-CsA in BOSTON-1 or BOSTON-2 must remain in the clinic for at least 4 hours for observation after the first inhalation. At all subsequent visits, one dose administered via inhalation will be monitored by the clinical trial center personnel. In case patients receiving L-CsA undergo the last visit for BOSTON-1 or BOSTON-2 (Visit 9) on the same day as for Visit 1 for BOSTON-3, they will take the first dose for Boston 3 in the evening of this day. This first dose will not be supervised by the site staff. Nebulization time per inhalation dose is approximately 6-10 minutes for the 5 mg dose and 9-13 minutes for the 10 mg dose. Inhalations will be performed BID approximately 12 hours apart through a mouthpiece by slow and deep respiration using the L-CsA eFlow. A high efficiency particulate air filter is used to prevent environmental contamination during exhalation.
|Full study title
|An Open Label Follow-Up Study to Evaluate the Long Term Safety and Efficacy of L-CSA in Patients with a Diagnosis of CLAD-BOS after they have completed the participation to BOSTON 1 and BOSTON 2 studies
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.
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.
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.
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.
Known hypersensitivity to L-CsA or to cyclosporine A.
Patients who experienced an AE related to study drug that led to permanent study drug discontinuation in BOSTON-1 or BOSTON-2.
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.
Pregnant women or women who are unwilling to use appropriate birth control to avoid pregnancy through their End of Study Visit.
Women who are currently breastfeeding.
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.
Patients who are currently participating in an interventional clinical trial, other than BOSTON-1 or BOSTON-2.
Psychiatric disorders or altered mental status precluding understanding of the informed consent process and/or completion of the necessary procedures.
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.

Get screened to confirm eligibility
You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.
Provide your consent to participate
If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.
If you decide to participate in a clinical trial or study, the research team will keep you informed of the study requirements and what you will need to do to throughout the study. For some trials or studies, your health care provider may work with the research team to ensure there are no conflicts with other medications or treatments.
