Non-small cell lung cancer (NSCLC) is a heterogeneous disease, commonly defined by genetic alterations in oncogenic drivers. Targeted therapies have transformed the management of oncogene-driven lung cancers, with targeted agents now approved in the United States for 7 distinct molecular alterations. Nonetheless, acquired resistance remains an ongoing challenge, underscoring the need for alternative therapeutic approaches. Immune checkpoint inhibitors targeting the programmed cell death 1 (PD-1) axis have emerged as important therapies in the management of advanced NSCLC, but the role of these agents in patients with oncogenic driver mutations remains unclear. Here, we focus on epidermal growth factor receptor-mutant and anaplastic lymphoma kinase-rearranged NSCLC as paradigms to explore the role of immune checkpoint inhibitors in oncogene-driven NSCLC. We provide an overview of the clinical data examining programmed death ligand 1 (PD-L1) inhibitor monotherapy, PD-(L)1 inhibitors, and tyrosine kinase inhibitor combinations, as well as combinations of PD-(L)1 inhibitors and chemotherapy.
