Smith, MD, PhD, FACP, Chief Medical Officer at Kapadi, about PD-1/VEGF bispecific antibodies and their implications for immuno-oncology. The opening also considers China’s growing role in oncology innovation and the challenge of making locally generated evidence relevant to global development.\nPatrick asks whether ivonescimab is a new molecular design class or a more convenient way to combine familiar targets. Scott discusses cooperative binding, HARMONi-2 and HARMONi-6, and the unanswered question of whether the bispecific format offers an advantage over two separate antibodies. The conversation then turns to programs built on pembrolizumab: what should change for new studies, trials already underway, and settings where VEGF-directed therapy is unsuitable or unproven?\nKey Takeaways\nDual PD-1 and VEGF targeting has precedents. Ivonescimab’s cooperative binding remains a mechanistic hypothesis to test against appropriate alternatives.\nA new backbone could change comparator choice, differentiation, and the relevance of studies using pembrolizumab as their default control.\nThe decision depends on indication, trial maturity, the partner drug’s rationale, and whether patients can receive VEGF-directed therapy.\n\nFeatured Expert\nScott E. Smith, MD, PhD, FACP, is Chief Medical Officer at Kapadi and a physician-scientist with more than 20 years of leadership in hematology, oncology, and clinical research. As Senior Vice President and Global Head of Hematology at Parexel, he oversaw global clinical trial operations across more than 20 countries. As founder and CEO of Chemosabe Consulting, he has advised more than 15 pharmaceutical and biotechnology companies on clinical development and immunotherapy strategy, contributing to the launch of four hematology and oncology therapies.\nPreviously, Dr. Smith served as Associate Cancer Center Director and Section Chief of Hematology at Loyola University Medical Center, where...","thumbnail_url":"https://img.transistorcdn.com/VEApGY9kGCRBCWdXiyY2M4SbT8Aa9OebLNCW4IYaXZo/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS82Yzgx/ZDVhMTE4YmE1Nzcw/YjRiNTcxZDMzNjA2/YWU0MC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
