The goal of the study is to collect data on patients treated outside of a clinical trial (in routine clinical practice) with standard of care osimertinib with or without chemotherapy in Epidermal Growth Factor Receptor (EGFR)-mutant Non-Small Cell Lung Cancer (NSCLC) to better understand the safety and effectiveness of these standard of care regimens.
Patient must have a pathologically-confirmed diagnosis of non-small cell lung cancer (NSCLC).
Patient must have advanced disease, defined as IIIB (not amenable to definitive multi-modality therapy), IIIC, or IV (includes local or distant 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) 8th edition staging criteria.
Patient tumor must have somatic activating sensitizing mutation in EGFR (e.g., but not limited to Exon 19 deletion, L858R, E709X, G719X, exon 19 insertions, L861Q, S768I). Patients with non-sensitizing mutations in EGFR (EGFR exon 20 insertions) are not eligible. Plasma, cytology, or tumor tissue can be utilized for standard of care mutation testing.
Prior chemotherapy and/or immunotherapy administered as primary treatment for NSCLC before EGFR mutation was identified is allowed ≤ 45 days of study registration to allow for return of sequencing information.
Prior treatment with osimertinib administered as primary treatment for NSCLC is allowed ≤ 30 days of study registration (prior treatment with any other EGFR TKI agent is not allowed).
Patient must not be participating in EA5182 or any other cancer treatment trial. Osimertinib or osimertinib + chemotherapy/immunotherapy given as first-line treatment for this disease cannot be given as part of a clinical trial.
Patients that have received prior radiation therapy in any setting for this disease are eligible.
Adults age ≥ 18 years.
