The Evolving Landscape of Bispecific Antibodies in Hematologic and Solid Tumors

Dr. Hope Rugo and Dr. Giuseppe Curigliano discuss recent developments in the field of bispecific antibodies for hematologic and solid tumors, including strategies to optimize the design and delivery of the immunotherapy.

TRANSCRIPT

Dr. Hope Rugo: Hello and welcome to By the Book, a podcast series from ASCO that features engaging conversations between editors and authors of the ASCO Educational Book. I am your host, Dr. Hope Rugo. I am the director of the Women's Cancers Program and division chief of breast medical oncology at the City of Hope Cancer Center. I am also the editor-in-chief of the Educational Book.

Bispecific antibodies represent an innovative and advanced therapeutic platform in hematologic and solid tumors. And today, I am delighted to be joined by Dr. Giuseppe Curigliano to discuss the current landscape of bispecific antibodies and their potential to reshape the future of precision oncology.

Dr. Curigliano was the last author of an ASCO Educational Book piece for 2025 titled, "Bispecific Antibodies in Hematologic and Solid Tumors: Current Landscape and Therapeutic Advances." Dr. Curigliano is a breast medical oncologist and the director of the Early Drug Development Division and chair of the Experimental Therapeutics Program at the European Institute of Oncology in Milan. He is also a full professor of medical oncology at the University of Milan.

You can find our disclosures in the transcript of this episode.

Dr. Curigliano, Giuseppe, welcome and thanks for being here.

Dr. Giuseppe Curigliano: Thanks a lot for the invitation.

Dr. Hope Rugo: Giuseppe, I would like to first ask you to provide some context for our listeners on how these novel therapeutics work. And then perhaps you could tell us about recent developments in the field of bispecific antibodies for oncology. We are at a time when antibody-drug conjugates (ADCs) are all the rage and, trying to improve on the targeting of specific antigens, proteins, receptors in the field of oncology is certainly a hot and emerging topic.

Dr. Giuseppe Curigliano: So, thanks a lot. I believe really it was very challenging to try to summarize all the bispecific antibodies that are under development in multiple solid tumors. So, the first thing that I would like to highlight is the context and the mechanism of action of bispecific antibodies.

Bispecific antibodies represent a groundbreaking advancement in cancer immunotherapy, because these engineered molecules have the unique ability to target and simultaneously bind to two distinct antigens. That is why we call them bispecific. So typically, one antigen is
