Driving Best Practices Throughout the Treatment Journey for Patients with NSCLC with Actionable Alterations: A...

Non-small cell lung cancer (NSCLC) treatment has been revolutionized by the advent of targeted therapies for tumors harboring specific actionable alterations. Targeted agents are now approved for use in patients with advanced NSCLC with various drivers including ALK rearrangements, BRAF V600E mutations, EGFR mutations, ERBB2 mutations, KRAS G12C mutations, MET exon 14 skipping alterations, NTRK fusions, RET rearrangements, and ROS1 rearrangements. Importantly, the availability of these agents has raised the clinical question of how to optimally sequence their use alongside chemotherapy and/or immunotherapy strategies, which are indicated for broader populations. Key considerations include (i) evidence for better outcomes when first-line treatment is initiated following availability of molecular profiling data; (ii) the decreasing proportion of patients able to receive therapy in each successive treatment line; (iii) the efficacy of targeted agents demonstrated in either single-arm trials or head-to-head comparisons with chemotherapy and/or immunotherapy, as compared with evidence for poor or modest efficacy of immunotherapy in patients with tumors with actionable drivers; (iv) real-world data showing better outcomes of patients with tumors with actionable alterations who received targeted therapies compared with those who did not; (v) the generally favorable safety profile of targeted therapies, as well as the potential for increased toxicity when immunotherapy precedes certain targeted agents; and (vi) patient-centric factors including the greater ease of administration of oral targeted therapies over intravenous chemotherapy or immunotherapy strategies. In line with these considerations, guidelines typically recommend most targeted agents approved for first-line use as initial therapy over chemotherapy and/or immunotherapy. In this podcast, the authors discuss the current therapeutic landscape of NSCLC with actionable alterations and provide their perspectives on treatment algorithms, and how to optimally sequence therapies for patients with tumors harboring actionable alterations, using patient cases to illustrate key principles.
