Provided herein are trispecific antigen-binding proteins comprising a domain binding to CD3, a half-life extension domain, and a domain binding to a target antigen. Also provided are pharmaceutical compositions thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such trispecific antigen-binding proteins. Also disclosed are methods of using the disclosed trispecific antigen-binding proteins in the prevention, and/or treatment diseases, conditions and disorders.

Trispecific binding proteins and methods of use

The present invention provides bispecific antibody constructs of a specific Fc modality characterized by comprising a first domain binding to a target cell surface antigen, a second domain binding to an extracellular epitope of the human and/or the Macaca CD3e chain and a third domain, which is the specific Fc modality. Moreover, the invention provides a polynucleotide, encoding the antibody construct, a vector comprising this polynucleotide, host cells, expressing the construct and a pharmaceutical composition comprising the same.

Bispecific t cell engaging antibody constructs

Provided herein are KRAS G12C inhibitors, composition of the same, and methods of using the same. These inhibitors are useful for treating a number of disorders, including pancreatic, colorectal, and lung cancers.

Inhibitors of kras g12c and methods of using the same

The present invention provides bispecific antibody constructs of a specific Fc modality characterized by comprising a first domain binding to BCMA, a second domain binding to an extracellular epitope of the human and/or the Macaca CD3e chain and a third domain, which is the specific Fc modality. Moreover, the invention provides a polynucleotide, encoding the antibody construct, a vector comprising this polynucleotide, host cells, expressing the construct and a pharmaceutical composition comprising the same.

Bcma and cd3 bispecific t cell engaging antibody constructs

Disclosed herein are single chain variable fragment CD3 binding proteins with improved binding affinities, and robust aggregation profiles. Also described are multispecific binding proteins comprising a single chain variable fragment CD3 binding protein according to the instant disclosure. Pharmaceutical compositions comprising the binding proteins disclosed herein and methods of using such formulations are provided.

Single chain variable fragment cd3 binding proteins

The present disclosure relates to a bispecific antibody construct comprising a first binding domain which binds to human FLT3 on the surface of a target cell and a second binding domain which binds to human CD3 on the surface of a T cell. Moreover, the disclosure provides a polynucleotide encoding the antibody construct, a vector comprising said polynucleotide and a host cell transformed or transfected with said polynucleotide or vector. Furthermore, the disclosure provides a process for the production of the antibody construct of the disclosure, a medical use of said antibody construct and a kit comprising said antibody construct.

Antibody constructs for flt3 and cd3

BiTE® therapeutics are single chain antibody constructs harboring two binding moieties: one directed at a tumor associated antigen and one directed at the CD3e protein, which trigger T cell dependent cellular cytotoxicity (TDCC) against targeted cancer cells. Here, we evaluated the suitability of ENPP3 as a potential BiTE® target. The ENPP3 mRNA is highly differentially expressed in clear cell Renal Cell Carcinoma (ccRCC) and the ENPP3 protein is detected with high uniformity and intensity in ccRCC tumor samples by immunohistochemistry. We demonstrated the surface expression of this protein in Renal Cancer cell lines and confirmed that the ENPP3 protein was highly restricted to the luminal side of normal epithelial layers in which it was detected (proximal renal tubules, bronchial epithelium, salivary glands). We developed highly potent anti-ENPP3 BiTE® molecules and demonstrated the in vitro TDCC activity of these molecules. Two anti-ENPP3 BiTE® molecules further demonstrated tumor formation inhibition activity in a human T cell / human target cell admixture mouse xenograft model.
