Abstract: Multispecific molecules that include i) a tumor-targeting moiety; and one, two or all of: (ii) an immune cell engager (e.g., chosen from an NK cell engager, a T cell engager, a B cell engager, a dendritic cell engager, or a macrophage cell engager); (iii) a cytokine molecule; and/or (iv) a stromal modifying moiety are disclosed. Additionally disclosed are nucleic acids encoding the same, methods of producing the aforesaid molecules, and methods of treating a cancer using the aforesaid molecules.

Abstract: The disclosure relates to fusion polypeptides comprising serum albumin or a functional variant thereof and GDF15 protein or a functional variant thereof and to pharmaceutical compositions that contain the fusion polypeptides, nucleic acids that encode the fusion polypeptides, methods of making the polypeptides and use of the polypeptides to decreasing appetite, decreasing body weight and treating metabolic diseases.

Abstract: The here described invention discloses a combination of a top and bottom loop binder library using the CD and the FG loops of a number of FnIII domains (FnIII) (e.g., FnIII7, FnIII10 and FnIII14) together with the surface exposed residues of the beta-sheet. The invention also pertains to a method of forming a library of FnIII domain polypeptides useful in screening for the presence of one or more polypeptides having a selected binding or enzymatic activity.

Abstract: Compositions and methods relating to regulatable chimeric antigen receptors (RCARs), where the intracellular signaling or proliferation of the RCAR can be controlled to optimize the use of an RCAR-expressing cell to provide an immune response, are provided. For example, a RCAR can comprise a dimerization switch that, upon the presence of a dimerization molecule, can couple an intracellular signaling domain to an extracellular recognition element, e.g., an antigen binding domain, an inhibitory counter ligand binding domain, or costimulatory ECD domain. An RCAR can be engineered to include an appropriate antigen binding domain that is specific to a desired antigen target and used in the treatment of a disease.

Abstract: The invention pertains to a natural-variant combinatorial library of fibronectin Type 3 domain (Fn3) polypeptides useful in screening for the presence of one or more polypeptides having a selected binding or enzymatic activity. The library polypeptides include (a) regions A, AB, B, C, CD, D, E, EF, F, and G having wildtype amino acid sequences of a selected native fibronectin Type 3 polypeptide or polypeptides, and (b) loop regions AB, CD, and EF having selected lengths (Bottom Loops). The Fn3 may also have loop regions BC, DE, and FG having wildtype amino acid sequences, having selected lengths, or mutagenized amino acid sequences (Top Loops).
