Summary: Background:~Bronchiolitis obliterans syndrome (BOS) is a complication people can experience after hematopoietic stem cell transplant. It usually affects people with chronic graft versus host disease (cGVHD). This occurs when donor stem cells attack the cells of the person who received them. BOS reduces airflow and oxygen levels in the body. It may be caused by neutrophil elastase in the body. Rese...

Summary: Hematopoietic stem cell transplant (HSCT) is an effective but toxic therapy and pulmonary morbidity affects as many as 25% of children receiving transplant. Early pulmonary injury includes diffuse alveolar hemorrhage (DAH), thrombotic microangiopathy (TMA) interstitial pneumonitis (IPS) and infection, while later, bronchiolitis obliterans is a complication of chronic GVHD associated with severe mo...

Summary: Hematopoietic stem cell transplant (HSCT) is an effective but toxic therapy, and lung injury affects as many as 25% of children receiving HSCT. Improved transplant techniques and major improvements in survival mean that HSCT is being more widely used, and more mismatched grafts are being used. Bronchiolitis obliterans (BO) is a major limitation of pediatric HSCT success as BO is commonly diagnosed...

Summary: This observational trial studies whether respiratory viruses are the cause of lung disease (bronchiolitis obliterans syndrome [BOS] or graft-versus-host disease of the lung) and changes in lung function in patients who have received a donor stem cell transplant. Patients with chronic graft-versus-host disease are at higher risk of developing BOS. Studies have also shown that patients who had a res...

Summary: This study investigates a type of cell, called abnormal clonogenic epithelial cells, in patients with bronchiolitis obliterans syndrome who have had an donor stem cell transplant or a lung transplant. Learning more about clonogenic cells in these patients may help doctors to detect signs of bronchiolitis obliterans syndrome earlier in future patients.

Summary: This phase I trial studies how well itacitinib works for the treatment of bronchiolitis obliterans syndrome after donor hematopoietic cell transplant. Itacitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Summary: Lung transplantation is the curative treatment for end-stage respiratory failure involving highly selected patients. In 2018, the International Transplant Registry counts 69200 lung transplants among 260 transplant centers. Between 2010 and June 2017, the 3-month survival rate of patients after lung transplantation is 90%. The causes of early death are primary graft failure, renal failure, infecti...

Summary: The primary aim of this study is to determine prospectively the viral and C. pneumoniae infection prevalence and outcomes of infections in lung transplant recipients. The study will also determine the correlation of C. pneumoniae infection with the development of obliterans in lung transplant recipients.

Summary: The Lung Clearance Index, measured by multiple breath washout, is a measure of lung function that is considered a research tool in Canada as the device used to measure it is not approved by Health Canada. The study will assess lung function in patients undergoing routine lung function testing for clinical indications (Cystic Fibrosis and Other Respiratory Diseases). In addition, healthy controls o...

Summary: 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.

Summary: Lung transplantation (TxP) is now a validated treatment of end-stage pulmonary diseases, but long-term graft and patient survival are still hampered by the development of chronic allograft dysfunction (CLAD) affecting > 50% of patients.~The investigators propose to conduct a phase III clinical randomized trial that will assess the efficacy of Nintedanib to hamper the lung decline in LTx recipients...

Summary: Bronchiolitis Obliterans Syndrome (BOS) is a major complication of Hematopoietic Stem cell Transplantation (HSCT) occurring in the context of chronic GVHD and associated with a poor prognosis. The diagnosis of BOS is based on functional (Pulmonary Functional Tests) and morphological criteria (chest CT-scan). Early diagnosis of BOS represents an unmet need and would facilitate early therapeutic int...
