Advancing nucleic acid therapeutics with circular RNA

“...the key realization is that optimizing each component individually...is necessary but not sufficient.”In this podcast episode, Jokūbas Leikauskas, Editor, BioInsights, speaks to Trevor Hallam, who served as Chief Scientific Officer of Sail Biomedicines until July 2025. The interview, recorded in June 2025, explores advances in RNA therapeutics, particularly circular RNA (circRNA or eRNA) technologies, and how they may help overcome current limitations in delivery, durability, and specificity for applications such as CAR-T cell therapies and autoimmune disease treatment.
