Extracorporeal Photopheresis for Medicare Recipients of Lung Allografts

The primary aims of this study is to determine the efficacy and tolerability of Extracorporeal Photopheresis (ECP) for the treatment of either Refractory Bronchiolitis Obliterans Syndrome (BOS) patients (258 at cessation of enrollment April 7, 2022) or Newly Diagnosed (22 as of enrollment Hold February 2022) Bronchiolitis Obliterans Syndrome patients after lung transplantation. In compliance with the Centers for Medicare and Medicaid Services' (CMS) Coverage with Evidence Development (CED) decision, the study will collect specified demographic, comorbidity, treatment, and outcome data exclusively for Medicare beneficiaries who are treated with ECP for either refractory or New BOS.

Nintedanib in Patients With Bronchiolitis Obliterans Syndrome Following Hematopoietic Stem Cell Transplantation

This study investigates the safety and tolerability of Nintedanib in patients with bronchiolitis obliterans syndrome (BOS) following allogeneic hematopoietic cell transplantation. All study patients with BOS will be treated with the study drug Nintedanib (300 mg/day) as an add-on therapy to their basic immunosuppressive treatment over a 12-months treatment period.

Mechanisms and Targeted Therapy of Airway Basal Cell Dysfunction in Bronchiolitis Obliterans Syndrome

This experimental study aims to investigate the pathogenesis of bronchiolitis obliterans syndrome (BOS) and provide a basis for clinical diagnosis and treatment. The core research question is: whether there is a causal relationship between stem cell dysfunction induced by the inflammatory microenvironment and airway injury repair during the pathological process of BOS? Researchers will collect alveolar lavage fluid specimens from participants and healthy individuals to isolate distal small airway stem cells for subsequent scientific research and comparative analysis, thereby revealing the pathological mechanisms of BOS, exploring precise intervention targets, and developing innovative therapeutic strategies to improve patient prognosis, long-term survival rates, and quality of life.
