Bronchoscopy With Bronchoalveolar Lavage in Identifying Biomarkers of Response to Immune Checkpoint Inhibitors in Patients With Non-small Cell or Small Cell Lung Cancer

2016-10-19 02:38:21 | BioPortfolio


This pilot clinical trial studies how well bronchoscopy with bronchoalveolar lavage works in identifying biomarkers of response to immune checkpoint inhibitors in patients with non-small cell or small cell lung cancer. Bronchoscopy uses a thin, tube-like instrument inserted through the nose or mouth to view the inside of the trachea, air passages, and lungs. Bronchoalveolar lavage washes out the bronchi and alveoli by flushing with a fluid. Bronchoscopy with bronchoalveolar lavage may make it easier to help determine biomarkers that are more present in some cancers than others that will help determine which individuals have a greater or lesser chance of benefiting from immunotherapy.



I. To discover predictive immune biomarkers of response to immune checkpoint inhibitor therapy in individuals with primary lung cancer.


I. To determine biomarkers that may be predictive of treatment related adverse events, specifically pneumonitis.

II. To further elucidate lung immunologic microenvironment by performing single cell analysis in addition to mass cytometry (Cytof) on cells of bronchoalveolar lavage.


Patients undergo bronchoscopy with bronchoalveolar lavage over 45 minutes.

After completion of study, patients are followed up at 3, 6, 12, and 24 months.

Medical and Biotech [MESH] Definitions

Washing out of the lungs with saline or mucolytic agents for diagnostic or therapeutic purposes. It is very useful in the diagnosis of diffuse pulmonary infiltrates in immunosuppressed patients.

Washing liquid obtained from irrigation of the lung, including the BRONCHI and the PULMONARY ALVEOLI. It is generally used to assess biochemical, inflammatory, or infection status of the lung.

A method of analyzing the variation in utilization of health care in small geographic or demographic areas. It often studies, for example, the usage rates for a given service or procedure in several small areas, documenting the variation among the areas. By comparing high- and low-use areas, the analysis attempts to determine whether there is a pattern to such use and to identify variables that are associated with and contribute to the variation.

Endoscopic examination, therapy or surgery of the bronchi.

Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.
