Abstract: The present disclosure is generally directed to compositions that include antibodies, e.g., monoclonal, antibodies, antibody fragments, etc., that specifically bind a CD33 polypeptide, e.g., a mammalian CD33 or human CD33, and use of such compositions in preventing, reducing risk, or treating an individual in need thereof.

Abstract: Described herein are high affinity antigen binding constructs, e.g., antibodies, directed to the ECD2 domain of HER2. The antigen-binding constructs comprise at least one antigen-binding polypeptide construct that binds to ECD2 of HER2 (HER2 ECD2) with increased affinity compared to a wild-type 2C4 antibody. Such antigen-binding polypeptide constructs comprise one or more amino acid modifications in the framework region and/or CDRs compared to the amino acid sequence of a wild-type 2C4 antibody that increase affinity of the antigen-binding polypeptide construct for ECD2 by 2-fold or greater. The antigen-binding constructs can inhibit the growth of HER2-expressing breast cancer cells and gastric cancer cells. Antigen-binding constructs in biparatopic format are internalized in HER2-expressing cells.

Abstract: The present disclosure relates to antidotes to anticoagulants targeting factor Xa. The antidotes are factor Xa protein derivatives that bind to the factor Xa inhibitors thereby substantially neutralizing them but do not assemble into the prothrombinase complex. In one embodiment, the derivatives described herein lack or have reduced intrinsic coagulant activity.

Abstract: Stabilized TCR constructs comprising a TCR alpha chain polypeptide having a variable alpha (V?) domain and a constant alpha (C?) domain and a TCR beta chain polypeptide having a variable beta (V?) domain and a constant beta (C?) domain. The TCR constructs are stabilized by the introduction into the C? domain and/or the C? domain of stabilizing mutations such as non-naturally occurring disulfide bonds between the C? domain and the C? domain (an interchain disulfide bond), non-naturally occurring intrachain disulfide bonds, point mutations, loop truncation mutations, and combinations thereof. TCR fusion proteins comprising one or more of the TCR constructs and a scaffold and/or other biologically active moiety are also described.

Abstract: Heterodimeric Fc variants comprising one or more asymmetric amino acid mutations in the CH2 domain and having increased selectivity of binding to Fc?RIIb as compared to a parental Fc region, polypeptides comprising the heterodimeric Fc variants and polynucleotides encoding the heterodimeric Fc variants. The one or more asymmetric mutations comprise replacement of a loop in the CH2 domain, a mutation at position 236 in the CH2 domain, or a combination of replacement of a loop in the CH2 domain and a mutation at position 236 in the CH2 domain.

Abstract: Provided herein are anti-TREM1 antibodies and related methods of making and using anti-TREM1 antibodies. Also provided are methods and compositions for enhancing an immune response and/or for the treatment of an immune-related condition in an individual, e.g., cancer, comprising killing, disabling, or depleting non-stimulatory myeloid cells using an anti-TREM1 antibody or antigen binding fragment thereof.

Abstract: Antibody-drug conjugates (ADCs) are described, comprising anti-TM4SF1 antibodies, antigen-binding fragments thereof, a linker and a drug. The drug is an inhibitor of tubulin polymerization. Methods of use of the ADCs are also described.

Abstract: Provided herein are anti-MARCO antibodies. Provided are also methods of generating and using anti-MARCO antibodies.

Abstract: This invention provides for a fusion protein between a single chain TNFR2 Selective Agonist protein (scTNFR2 Selective Agonist) and a dimerization domain, such as an IgGFc protein. The single chain TNFR2 Selective Agonist moiety provides a therapeutic activity by selectively activating the TNFR2 form of the TNF-? receptor, thus selectively stimulating Tregs and/or increasing myelin deposition.
