The purpose of this study is to use archival tissue samples and RW data to generate HER3 expression prevalence data within the NSCLC population and by patient characteristics (e.g., ethnicity, histology, smoking status, age, prior treatment, etc.).~The primary objective of the study will analyze and assess archival tissue specimens and associated RW data to:~Increase the understanding of HER3 expression in NSCLC among HCPs and the medical community~Generate evidence to support future clinical strategies in this area
There is currently a lack of published HER3 expression prevalence data among non-small cell lung cancer (NSCLC) patients. The estimation of HER3 expression prevalence in this population using archival tissue samples and the assessment of associated patient characteristics in real world (RW) data will ultimately inform clinical strategy and increase awareness among health care providers (HCPs) and the greater medical community to improve patient care.
