Gefitinib in combination with bevacizumab as first-line therapy seems to be a favorable and well-tolerated treatment for patients with advanced NSCLC with activating EGFR gene mutations, especially those with EGFR exon 19 deletion mutations, although the primary end point was not met because the lower limit of the CI was less than 40%.
There was a somewhat lower incidence of ILD with erlotinib therapy than with gefitinib therapy, despite no statistically significant difference. Patient selection based on awareness by Japanese physicians of the risk factors for ILD, rather than the type of agent, may explain the difference in ILD incidence between the two treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
