Abstract: The invention relates to agents and methods for targeted delivery of payloads to cells. The agents and methods are useful for delivering therapeutic or diagnostic agents to target cells. In one embodiment, the invention involves administering RNA encoding a peptide or polypeptide (docketing compound) comprising a binding moiety (primary targeting moiety) binding to target cells and a further binding moiety (secondary target) binding to an agent that comprises a payload (effector probe). Following expression of the RNA, the primary targeting moiety may bind to a target antigen such as a cancer antigen on cancer cells and then a secondary targeting moiety comprised in the effector probe may target the secondary target to thereby precisely deliver a “payload” to the target cells such as cancer cells.

Abstract: The present invention relates to the diagnosis and treatment of diseases expressing Fibronectin Extra Domain B (EDB) such as diseases characterized by tissue remodeling and/or angiogenesis, in particular cancerous diseases, such as head and neck, brain, colorectal, lung, prostate and breast cancer. More particularly, the invention concerns peptides targeting Fibronectin Extra Domain B.

Abstract: The present invention provides molecules that mimic antigenic determinants of the integral transmembrane protein claudin 18.2 (CLDN18.2). These molecules compete with CLDN18.2 for binding to a CLDN18.2 binding domain, e.g. a CLDN18.2 binding domain of an antibody, and are capable of detecting antibodies against CLDN18.2. The mimotopes of the invention may be used to generate or inhibit immune responses in animals and preferably humans. Furthermore, they can be used for purposes of detecting agents comprising a CLDN18.2 binding domain in biological samples as well as for purifying agents comprising a CLDN18.2 binding domain.

Abstract: The present disclosure generally relates to therapies involving immune effector cells such as T cells engineered to express antigen receptors such as T cell receptors (TCRs) or chimeric antigen receptors (CARs). It is demonstrated herein that such antigen receptor-engineered immune effector cells may be generated in vitro/ex vivo as well as in vitro by delivering nucleic acid encoding an antigen receptor for genetic modification to cells using particles comprising the nucleic acid and a targeting molecule for targeting the immune effector cells, wherein the targeting molecule is a designed ankyrin repeat protein (DARPin). In particular, DARPins are described herein which are high-affinity binders for CDS binding to the CDS receptor on human and non-human primate (NHP) cells. Nanoparticles functionalized with CD8? targeting DARPins (CDS-DARPin) can deliver genes exclusively and specifically to human CD8+ T cells in vitro and in vivo.

Abstract: The present invention provides molecules that mimic antigenic determinants of the CD3 (cluster of differentiation 3) T-cell co-receptor epsilon chain (CD3?). These molecules compete with CD3? for binding to a CD3? binding domain. e.g. a CD3? binding domain of an antibody, and are capable of detecting antibodies against CD3?. The mimotopes of the invention may be used to generate or inhibit immune responses in animals and preferably humans. Additionally, they may serve as tools for anti-CD3? antibody purification and the detection of anti-CD3? antibodies in biological samples.
