Alectinib combined with cobimetinib in ALK-Rearranged lung Cancer: A phase IB study.

Introduction: Anaplastic lymphoma kinase rearranged (ALK + ) lung cancers often develop ALK-independent resistance mechanisms that reactivate the mitogen-activated protein kinase pathway signaling pathway. We therefore evaluated alectinib combined with the MEK inhibitor cobimetinib in metastatic ALK + lung cancer.

Materials And Methods: This phase Ib study employed a 3 + 3 design.

Phase I/II Investigator-Initiated Study of Olaparib and Temozolomide in SCLC: Final Analysis and CNS Outcomes.

Purpose: Temozolomide plus PARP inhibition has shown promise in small cell lung cancer (SCLC). We previously reported outcomes from the first 50 patients (cohort 1) of a phase I/II trial of olaparib/temozolomide in recurrent SCLC. In this study, we report a final analysis of this trial, including a second cohort with an alternate dosing strategy and an exploratory analysis of central nervous system (CNS)-specific outcomes.

Arsenic exposure is associated with elevated sweat chloride concentration and airflow obstruction among adults in Bangladesh: a cross sectional study.

Arsenic is associated with lung disease and experimental models suggest that arsenic-induced degradation of the chloride channel CFTR (cystic fibrosis transmembrane conductance regulator) is a mechanism of arsenic toxicity. We examined associations between arsenic exposure, sweat chloride concentration (measure of CFTR function), and pulmonary function among 285 adults in Bangladesh. Participants with sweat chloride ≥ 60 mmol/L had higher arsenic exposures than those with sweat chloride < 60 mmol/L (water: median 77.
