KRAS mutation is the most frequent molecular alteration found in advanced NSCLC; it is associated with a poor prognosis without available targeted therapy. Treatment options for NSCLC have been recently enriched by the development of immune checkpoint inhibitors (ICIs), and data about its efficacy in patients with KRAS-mutant NSCLC are discordant. This study assessed the routine efficacy of ICIs in advanced KRAS-mutant NSCLC. ⋯ For patients with KRAS-mutant NSCLC (all mutational subtypes), the efficacy of ICI is similar to that for patients with other types of NSCLC. PD-L1 expression seems to be more relevant for predicting the efficacy of ICIs in KRAS-mutant NSCLC than it is in other types of NSCLC.

Randomized Controlled Trial
Osimertinib Plus Durvalumab versus Osimertinib Monotherapy in EGFR T790M-Positive NSCLC following Previous EGFR TKI Therapy: CAURAL Brief Report.
Osimertinib is a third-generation EGFR-tyrosine kinase inhibitor (TKI). Durvalumab is an anti-programmed death ligand 1 monoclonal antibody. The phase III open-label CAURAL trial (NCT02454933) investigated osimertinib plus durvalumab versus osimertinib monotherapy in patients with EGFR-TKI sensitizing and EGFR T790M mutation-positive advanced NSCLC and disease progression after EGFR-TKI therapy. ⋯ Limited patient numbers preclude formal safety and efficacy comparisons between the two treatment arms. The combination of programmed cell death 1/programmed death ligand 1 inhibitors and EGFR-TKIs as therapy for NSCLC is not well understood, but it requires a careful approach if considered in the future.

Randomized Controlled Trial Multicenter Study
Nivolumab Versus Docetaxel in a Predominantly Chinese Patient Population With Previously Treated Advanced NSCLC: CheckMate 078 Randomized Phase III Clinical Trial.
Data on immuno-oncology agents in Chinese patients are limited despite a need for new therapies. We evaluated the efficacy and safety of nivolumab in a predominantly Chinese patient population with previously treated NSCLC. ⋯ This is the first phase III study in a predominantly Chinese population reporting results with a programmed death 1 inhibitor. In this population with previously treated advanced NSCLC, nivolumab improved OS versus docetaxel. Results were consistent with global CheckMate 017 and 057 studies.
