VivoCAR™ Anti-EIIIB (MOR03258) h(CD28-41BB-CD3z) CAR saRNA utilizes the saRNA platform to express the MOR03258 clone. For in vivo applications, the MOR03258 clone is distinguished by its high binding stability to the EIIIB splice variant within the tumor stroma. The intracellular replication of the saRNA backbone ensures a biological magnification effect, resulting in potent CAR expression that drives T-cell activation in situ, effectively targeting the tumor microenvironment and suppressing tumor growth through localized immune modification.

Description of Signaling Cassetes
The third-generation CD28-41BB-CD3ζ architecture employs a sequential costimulatory strategy, where the CD28 module drives rapid initial activation and metabolic reprogramming, while the 4-1BB component sustains long-term cellular viability and mitigates exhaustion. This tandem design, anchored by the CD3ζ signaling chain, synergistically amplifies downstream signal transduction, resulting in a balanced T-cell phenotype with robust effector capacity and prolonged durability. The integrated signaling cascade thus optimizes both kinetic expansion and persistence, enhancing antitumor efficacy.
