The All Wales Bi-specific Antibody Sub-Group has been established by the Cancer Network as a subgroup of the All Wales Systemic Anti-Cancer Therapy (SACT) Group. It aims to provide a forum for sharing best practice and develop tools and guidelines to support local services to manage the safe introduction of these new medicines into clinical practice. The group will also provide advice and a strategic steer for Bi- specific antibodies enabling a coordinated approach to service provision across Wales.
