摘要: The present disclosure provides fusion proteins with a multifunctional biologic design for programmed target engagement. In certain embodiments, the fusion proteins described herein provide for concurrent target antigen engagement and immune checkpoint or costimulatory receptor targeting. In certain aspects, the fusion protein is masked from presenting any on-target off-tissue action (i.e., toxicity) associated with target engagements. In certain embodiments, the fusion proteins provide a masked antigen binding domain as well as a masked immunomodulatory target binding domain, such that the programmed activation of one binding functionality results in the activation of the other binding functionality as well, thereby yielding a bispecific molecule. Thus, the disclosure also provides for methods of masking and conditional activation of antigen binding domains in specific target tissue setting and targeting and activation of immunomodulatory targets without severe adverse toxicity effects.
