This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PRIMARY OBJECTIVE: I. To evaluate the best objective response rate of osimertinib (AZD9291) among patients with EGFR exon 20 insertions. SECONDARY OBJECTIVES: I. To determine the safety profile of 160 mg once daily (QD) dose of osimertinib (AZD9291) in patients with EGFR Exon 20 insertion mutations. II. To determine the progression-free survival. III. To determine the overall survival. TERTIARY OBJECTIVES: I. To characterize molecular markers of response to treatment in circulating tumor deoxyribonucleic acid (DNA). II. To evaluate biomarkers of response to treatment through retrospecti…
Inclusion Criteria: * Participants must have a pathologically-confirmed diagnosis of non-small cell lung cancer (NSCLC) * Participants must have advanced disease - either stage IV disease, stage IIIB disease not amenable to definitive multi-modality therapy, or recurrent disease after a prior diagnosis of stage I-III disease. All staging is via the American Joint Committee on Cancer (AJCC)/International Association for the Study of Lung Cancer (IASLC) 7th edition staging criteria * An EGFR exon 20 insertion mutation must be detected in the tumor tissue. Patients may be enrolled in the study b…
