Phase 2 Study of AUY922 in NSCLC Patients With Exon 20 Insertion Mutations in EGFR

This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is being studied. It also means that the FDA has not yet approved the drug for your type of cancer or for any use outside of research studies. It has been found that some people with NSCLC have a change (mutation) in a certain gene called the EGFR gene. This mutated gene helps cancer cells grow. The majority of NSCLC patients with EGFR mutations achieve good outcomes with erlotinib or other EGFR inhibitor therapies, with a high response rate, prolonged progression-free survival and possibly improved overall survival from therapy. However, the 4% of EGFR mutant patients that harbor an exon 20 insertion mutation historically have reaped little benefit from EGFR-directed therapy due to the low affinity of this mutation for direct EGFR inhibitors, especially erlotinib and gefitinib (see Yasuda et al, Lancet Oncol 2011). This group of patients is ideal for studying other targeted therapeutic strategies that could affect the oncogene mutation in EGFR via alternative mechanisms. AUY922 is an investigational drug that may stop cancer cells from growing abnormally. This drug has been used in other research studies. Information from those other research studies suggests that AUY922 may be effective in killing cancer cells in patients with exon 20 insertion mutations in EGFR. The purpose of this study is to test the safety of AUY922 and determine how well AUY922 works for participants with advanced NSCLC and exon 20 insertion mutations in EGFR.
