Lung Cancer Highlights from ASCO 2016

This year, the Annual Meeting of the American Society of Clinical Oncology (ASCO) did not produce any truly groundbreaking revelations about new treatments for lung cancer. However, researchers did report quite a few positive findings, and some disappointing ones. I have summarized some of the more prominent presentations below. Continue reading…

New Drug May Overcome Resistance to Xalkori

The drug crizotinib (Xalkori) is used to treat non-small cell lung cancer (NSCLC) with mutations in the ALK gene. However, most patients develop resistance to the drug, usually because of further mutations in the ALK gene. A new ALK inhibitor drug, PF-06463922, may offer a solution. PF-06463922 blocked a variety of Xalkori-resistant mutant versions of ALK in cell cultures, and inhibited the growth of Xalkori-resistant ALK-mutant tumors in mice. PF-06463922 also combated tumor cells driven by mutations in ROS1, a gene closely related to ALK, in mouse models. Like Xalkori, PF-06463922 may therefore also be effective for NSCLC patients with ROS1 mutations. Finally, PF-06463922 was able to penetrate into the brain in multiple animal species–important because lung cancer often spreads to the brain.

Targeted Investigational Therapy Potential to Overcome Crizotinib Resistance in Lung Cancers

 PF-06463922, an investigational drug being developed by Pfizer Inc., has the potential to become a new treatment option for patients who have lung cancer harboring abnormalities in the ALK gene, according to preclinical results presented here at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, held Oct. 19-23.
