ESMO 2023 preview – conjugates, bispecifics and more
![](/apexonco/sites/default/files/styles/large/public/articles/Madrid_0.jpg?itok=xu6yfm0Q)
Antibody-drug conjugates look set to have a strong presence at this year’s instalment of ESMO, continuing the industry’s resurgence of this modality after years in relative obscurity. That much is clear from what little is known of the ESMO programme, which so far has revealed only the abstract titles for non-late-breaking presentations. Among ADCs and broadly related approaches there is of course a strong showing from projects that seek either to follow Enhertu with a straight anti-HER2 approach or that take a new twist on the Daiichi Sankyo/AstraZeneca juggernaut, for instance by combining its modality with antagonism against other members of the ErbB family. Among ADCs that, like Gilead’s Trodelvy, target TROP2, Merck & Co/Kelun’s sacituzumab tirumotecan will be closely watched given the promise it showed at ASCO earlier this year. Novel targets will also be on show, with interest undoubtedly being generated by raludotatug deruxtecan, a relatively low-profile member of the Daiichi stable, and Mabwell’s 9MW2821, one of few industry projects against the Nectin-4 antigen that is hit by Seagen’s Padcev.
