Anne Chiang, MD, PhD, on Targeting B7-H3 in Second-Line SCLC Treatment: Novel ADCs
IASLC WCLC 2026
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).
Alberto A. Chiappori, MD, of Moffitt Cancer Center, discusses findings from a phase I trial looking at the safety and efficacy of LB2102, an autologous CAR-T cell therapy targeting DLL3 and armored with a dominant-negative TGF-beta receptor, in pretreated patients with small cell lung cancer (SCLC) (Abstract OA05.02).
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).
Pedro Rocha, MD, PhD, of Vall d'Hebron University Hospital, presents data from the phase Ib DeLLphi-308 study, which investigated subcutaneous administration of the bispecific T-cell engager tarlatamab—which may improve convenience and produce lower peak serum concentrations, potentially reducing adverse events—compared with its usual intravenous administration among patients with extensive-stage small cell lung cancer (SCLC) (Abstract MO15.07).
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).
