As bispecific T-cell engagers (TCEs) gain traction in the oncology treatment landscape, cancer centres must develop robust clinical pathways to ensure their safe and efficient delivery. Given the limited experience of the Canadian medical oncology community with TCEs, collecting and publishing early clinical experiences with these novel agents will be essential to inform best practices and support their safe and effective adoption across the broader Canadian oncology community. The approval of tarlatamab, the first-in-class delta-like ligand 3 (DLL3)-targeted TCE for extensive-stage small cell lung cancer (ES-SCLC), underscores the importance of sharing early clinical experience with this agent, particularly given its unique safety profile, specific monitoring requirements, and use in a population that often has multiple comorbidities. Like other TCEs, tarlatamab is associated with cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), adverse events (AEs) that necessitate the development of dedicated protocols by medical oncologists and multidisciplinary inpatient and outpatient clinical teams to ensure prompt recognition and management of these associated toxicities. By sharing insights into administration protocols, dose ramp-up procedures, post-cycle 1 monitoring, and AE management strategies implemented at their centres, early adopters of tarlatamab can help other institutions develop and refine their own protocols more efficiently. Lessons learned during the early implementation phase, including the roles of various healthcare providers and the transition from inpatient to outpatient care, should facilitate the smoother integration of tarlatamab and other TCEs for solid tumours into clinical pathways across Canada.
