STING Agonist VB-85247 Induces Durable Antitumor Immune Responses by Intravesical Administration in a Non-Muscle-Invasive Bladder Cancer.

ABSTRACT: Bacillus Calmette-Guérin (BCG) is the current standard of care for non-muscle-invasive bladder cancer (NMIBC), but recurrence is common. Additional therapeutic options are a major unmet medical need for treating unresponsive patients. Stimulator of IFN genes (STING) plays a central role in mounting innate and adaptive immune responses to tumor cells, and activation of STING is a promising immunotherapeutic approach. In this study, we developed STING agonist VB-85247 for treating NMIBC by intravesical delivery as a strategy to provide a sustained period of exposure to bladder cancer cells while avoiding potential issues associated with intratumoral injection of STING agonists, which to date have shown only limited clinical efficacy. VB-85247 induced complete response in an orthotopic NMIBC
