S12 Ep28: Ivonescimab Improves PFS vs Pembrolizumab in Advanced PD-L1+ NSCLC: With Xiuning Le, MD, PhD

OncLive® On Air

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.
