Ivonescimab Improves PFS vs Pembrolizumab in Advanced PD-L1+ NSCLC: With Xiuning Le, MD, PhD

Welcome to OncLive On Air^®! I’m your host today, Jax DiEugenio.

OncLive On Air is a podcast from OncLive^®, which provides oncology professionals with the resources and information they need to provide the best patient care. In both digital and print formats, OncLive covers every angle of oncology practice, from new technology to treatment advances to important regulatory decisions.

In today’s episode, supported by Summit Therapeutics, we had the pleasure of speaking with Xiuning Le, MD, PhD, about the use of ivonescimab (SMT112) in patients with PD-L1–positive non–small cell lung cancer (NSCLC). Dr Le is an associate professor in the Department of Thoracic/Head and Neck Medical Oncology in the Division of Internal Medicine at The University of Texas MD Anderson Cancer Center in Houston.

The phase 3 HARMONi-2 trial (NCT05499390) investigated ivonescimab vs pembrolizumab (Keytruda) in patients with locally advanced or metastatic, PD-L1–positive NSCLC without sensitizing EGFR mutations or ALK translocations. At the preplanned interim analysis, at a median follow-up of 8.7 months (IQR, 7.1-10.3), the median progression-free survival was significantly longer in the ivonescimab arm (n = 198) vs the pembrolizumab arm (n = 200), at 11.1 months (95% CI, 7.3-not estimable) vs 5.8 months (95% CI, 5.0-8.2), respectively (stratified HR, 0.51; 95% CI, 0.38-0.69; 1-sided P < .0001). The objective response rates were 50% (95% CI, 43%-57%) and 39% (95% CI, 32%-46%) in these respective arms.

In our exclusive interview, Dr Le discussed the rationale for the HARMONi-2 trial, key findings from the study, and where these findings position the potential role of ivonescimab in the PD-L1–positive NSCLC treatment paradigm.
