NCT03311620
Needle biopsy samples are routinely collected to evaluate cytomorphology, immunohistochemical markers and for mutational analysis. With regular use of immunotheraputic interventions, needle biospy has become more frequent and requires bigger samples for an increasing battery of tests. There has been no clear consensus on which biopsy needle yields the best biopsy sample. It is unclear if large 19g needle offers better yield than a 22 g needle. Although previous studies comparing 21, 22 and 19g needles have suggested that larger needles yield larger biopsy sizes, conflictng studies have shown that larger biopsies lead to bloodier samples with potentially smaller fragments of tissue, offering no improvement in diagnostic, yield, adequacy or sample size. This study compares biopsy samples collected using 19g and 22g needles from patients of non small cell lung cancer (NSCLC) scheduled to undergo endobronchial ultrasound (EBUS) and transbroncial needle aspiration (TBNA).
NCT02926638
This randomized phase II/III compares rilotumumab when given together with erlotinib hydrochloride against erlotinib hydrochloride alone in treating patients with stage IV squamous cell lung cancer that has come back after previous treatment. This is a sub-study that includes all screened patients positive for the met proto-oncogene (MET)/hepatocyte growth factor (HGF) biomarker. HGF can interact with MET and can cause tumor cells to grow more quickly. Rilotumumab may decrease the activity of HGF and may be able to shrink tumors. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether giving rilotumumab with erlotinib hydrochloride works better than erlotinib hydrochloride alone (standard treatment) in treating squamous cell lung cancer.
