Study of EGF816 in Combination With Selected Targeted Agents in EGFR-mutant NSCLC

Inclusion Criteria: * Patients must have histologically or cytologically confirmed locally advanced (stage IIIB) or metastatic (stage IV) EGFR mutant (ex19del, L858R) NSCLC. * Requirements of EGFR mutation status and prior lines of treatment: * Treatment naive patients, who have locally advanced or metastatic NSCLC with EGFR sensitizing mutation (e.g., L858R and/or ex19del), have not received any systemic antineoplastic therapy for advanced NSCLC and are eligible to receive EGFR TKI treatment. Patients with EGFR exon 20 insertion/duplication are not eligible. Note: patients who have received only one cycle of chemotherapy in the advanced setting are allowed. * Patients who have locally advanced or metastatic NSCLC with EGFR sensitizing mutation AND an acquired T790M mutation (e.g., L858R and/or ex19del, T790M+) following progression on prior treatment with a 1st-generation EGFR TKI or 2nd-generation EGFR TKI. These patients may not have received more than 4 prior lines of antineoplastic therapy in the advanced setting, including EGFR TKI, and may not have received any agent targeting EGFR T790M mutation (i.e., 3rd-generation EGFR TKI). * Patients who have locally advanced or metastatic NSCLC with EGFR sensitizing mutation and a "de novo" T790M mutation (i.e., no prior treatment with any agent known to inhibit EGFR including EGFR TKI). These patients may not have received more than 3 prior lines of antineoplastic therapy in the advanced setting, and may not have received any …
