Bronchiolitis Obliterans Syndrome (BOS)

Bronchiolitis Obliterans Syndrome (BOS), also known as obliterative bronchiolitis (OB) or chronic lung allograft rejection, is caused by T-cell mediated inflammation that leads to blockage of bronchioles, the small and medium airways in the lungs, resulting in respiratory failure and death. BOS most commonly affects people who have received lung or stem cell transplantation, although it is also associated with autoimmune disease and exposure to environmental contaminants. An estimated 15,000 lung transplantation and 9,500 allogeneic hematopoietic stem cell transplantation recipients worldwide are affected by BOS.  To view experts discuss their clinical experience with BOS and the BOSTON-1 and BOSTON-2 studies, please visit here.

Liposomal Cyclosporine A for Inhalation (L-CsA-i)

Breath Therapeutics’ lead candidate, L‑CsA‑i, is a novel liposomal formulation of cyclosporine A designed for inhaled delivery to the lungs. Calcineurin inhibitors (CNIs), like cyclosporine A, are highly potent immunosuppressive drugs and a cornerstone of lung transplant medicine. Due to a narrow therapeutic window, mainly caused by nephrotoxicity, the systemic administration of CNIs cannot achieve sufficient drug levels in the bronchiolar tissue needed to treat BOS. L‑CsA‑i is administered via a customized drug-specific investigational eFlow® nebulizer (PARI Pharma GmbH). The drug-device combination is designed to deliver L-CsA-i to the site of disease in the lung while minimizing systemic exposure. L‑CsA‑i is an investigational compound and its safety and efficacy have not been established. It is not approved for use by any regulatory authority.

BOSTON Development Program

L-CsA-i is being developed for the treatment of BOS in patients age six and older. Five clinical trials are currently planned. BOSTON-1 and BOSTON-2 are pivotal Phase 3 studies with BOS following lung transplantation. BOSTON-3 is an open-label extension study for all study participants who complete BOSTON-1 or BOSTON-2. BOSTON-4 is a Phase 2 study and will be the first trial of L‑CsA‑i in adults with BOS following allogeneic hematopoietic stem cell transplant.  BOSTON-5 is a Phase 2 study in pediatric patients with BOS.

Breath Therapeutics

Founded in 2016, Breath Therapeutics is a private, venture-backed clinical stage biopharmaceutical company specializing in advanced inhaled therapeutics for severe respiratory diseases with high unmet medical need. The company’s proprietary drug formulations have been specifically designed for inhaled administration with exclusively licensed, high performance nebulizer technology. L‑CsA‑i, Breath Therapeutics’ lead asset, is advancing as the first therapy for BOS, a rare and devastating lung disease with no currently available treatment.
