Alexander Drilon, MD, on Advanced Metastatic ROS1-Positive NSCLC: Zidesamtinib in TKI-Naive Patients
IASLC WCLC 2026
Alexander Drilon, MD, of Memorial Sloan Kettering Cancer Center, presents efficacy and safety data from a phase II cohort of the ARROS-1 trial, which included patients with locally advanced or metastatic ROS1-positive non–small cell lung cancer (NSCLC) who were naive to tyrosine kinase inhibitor (TKI) therapy (Abstract PL03.06).
Alexander I. Spira MD, PhD, FACP, FASCO, of Virginia Cancer Specialists and US Oncology, discusses findings from a global phase I study of izalontamab brenitecan (BL-B01D1), an antibody-drug conjugate comprising an EGFR x HER3 bispecific antibody conjugated to a novel topoisomerase 1 inhibitor payload via a stable tetrapeptide-based cleavable linker. In a randomized dose-expansion cohort, the agent demonstrated promising efficacy with a tolerable safety profile in patients with previously treated EGFR-mutated non–small cell lung cancer (NSCLC) (Abstract OA10.01).
Anne Chiang, MD, PhD, of Yale University School of Medicine, provides commentary on two China-based phase III studies presented in Presidential Symposium 1: TAISHAN-02, which looked at the antibody-drug conjugate (ADC) tambotatug pelitecan vs topotecan among patients with relapsed small cell lung cancer (SCLC), and ARTEMIS-008, which looked at another ADC, risvutatug rezetecan, among patients with SCLC whose disease progressed on and after platinum-based chemotherapy. Both agents target B7-H3 and showed promising efficacy and safety in this setting (Abstracts PL02.03 and PL02.04).
Giannis S. Mountzios, MD, of Henry Dunant Hospital Center, reviews primary results from the phase III EVOKE-03/KEYNOTE D46 trial, which evaluated first-line sacituzumab govitecan in combination with pembrolizumab in patients with metastatic non–small cell lung cancer (NSCLC) and a PD-L1 tumor proportion score of 50% or higher (Abstract PL02.06).
Jonathan W. Goldman, MD, of the University of California, Los Angeles, reviews findings from the phase II DeLLphi-309 study, which examined the efficacy, safety, and pharmacokinetics of tarlatamab extended-interval dosing regimens (20 mg every 3 weeks and 30 mg every 4 weeks) in comparison to the usual dose of 10 mg every 2 weeks in patients with small cell lung cancer (SCLC) (Abstract OA05.01).
Roy S. Herbst, MD, PhD, of Dartmouth Cancer Center, discusses 8-year overall survival data from the landmark ADAURA trial, which showed the sustained long-term benefit of adjuvant therapy with osimertinib for patients with completely resected, EGFR-mutated stage IB–IIIA non–small cell lung cancer (NSCLC) (Abstract PL03.01).
