Patent application number | Description | Published |
20090048122 | Stabilized polypeptide compositions - The invention is based, at least in part, on the development of stabilized binding molecules that consist of or comprise a stabilized scFv and methods for making such stabilized molecules. | 02-19-2009 |
20090130105 | COMPOSITIONS THAT BIND MULTIPLE EPITOPES OF IGF-1R - The instant invention is based, at least in part on the finding that binding molecules which bind to different epitopes within IGF-1R result in improved IGF-1 and/or IGF-2 blocking capabilities when compared to binding molecules that bind to a single IGF-1R epitope. The instant invention provides compositions that bind to multiple epitopes of IGF-1R, for example, combinations of monospecific binding molecules or multispecific binding molecules (e.g., bispecific molecules). Methods of making the subject binding molecules and methods of using the binding molecules of the invention to antagonize IGF-1R signaling are also provided. | 05-21-2009 |
20090155255 | CD23 BINDING MOLECULES AND METHODS OF USE THEREOF - The invention is based, at least in part, on the development of multivalent and stabilized forms of CD23 binding molecules and methods of use thereof for the treatment of immune cell disorders, including leukemias or lymphomas such as CLL. | 06-18-2009 |
20090252729 | Single-chain Fc (scFc) regions, binding polypeptides comprising same, and methods related thereto - The present invention features inter alia polypeptides comprising an Fc region comprising genetically-fused Fc moieties. In addition, the instant invention provides, e.g., methods for treating or preventing a disease or disorder in subject by administering the binding polypeptides of the invention to said subject. | 10-08-2009 |
20090258420 | Altered polypeptides, immunoconjugates thereof, and methods related thereto - The present invention features inter alia altered binding polypeptides having engineered cysteine residues or analogs thereof at a predetermined site within, for example, a constant region domain or a portion thereof. The engineered cysteine residues or analogs thereof provide sites for conjugating effector moieties (e.g. diagnostic or therapeutic agents) that impart novel functionality to the binding polypeptide, preferably without interfering with a desirable property (e.g. an Fc-mediated effector function). The invention includes methods for the rational design of such altered polypeptides, as well as methods for modifying (ie. conjugating) the altered polypeptides with desirable effector moieties. Particular modified binding polypeptides (ie. immunoconjugates) of altered binding polypeptides and methods for utilizing such modified binding polypeptides as protein-based therapeutics are also provided. | 10-15-2009 |
20100008906 | Cripto binding molecules - The invention pertains to humanized forms of an anti-CRIPTO antibody and portions thereof. In one embodiment, the variable regions of these antibodies or polypeptides comprising them (e.g., full-length antibodies or domain deleted antibodies) can be used to treat disorders, such as cancer. | 01-14-2010 |
20100093980 | Methods of Humanizing Immunoglobulin Variable Regions Through Rational Modification Of Complementarity Determining Residues - The present invention is based, at least in part, on the discovery that strategic modifications of non-human donor antibody CDR residue(s) can be used to humanize antibodies. Such modifications modulate the 3D structural fit between donor antibody CDRs and human acceptor antibody framework regions that comprise the variable domains of a CDR-grafted antibody. Whereas prior art methods of humanization have relied on making framework substitutions (in which selected human framework residues are backmutated to the corresponding amino acid residue present in the non-human donor antibody), the instant invention is based, at least in part, on a method of humanizing antibodies in which selected CDR residues, and optionally adjacent FR residues, are changed in order to accommodate differences in FR amino acid sequences between donor and acceptor antibodies. | 04-15-2010 |
20110243966 | SINGLE CHAIN Fc (ScFc) REGIONS, BINDING POLYPEPTIDES COMPRISING SAME, AND METHODS RELATED THERETO - The present invention features inter alia polypeptides comprising an Fc region comprising genetically-fused Fc moieties. In addition, the instant invention provides, e.g., methods for treating or preventing a disease or disorder in subject by administering the binding polypeptides of the invention to said subject. | 10-06-2011 |
20120003210 | NEONATAL Fc RECEPTOR (FcRn)- BINDING POLYPEPTIDE VARIANTS, DIMERIC Fc BINDING PROTEINS AND METHODS RELATED THERETO - The compositions and methods of the present invention are based, in part, on our discovery that an effector function mediated by an Fc-containing polypeptide can be altered by modifying one or more amino acid residues within the polypeptide (by, for example, electrostatic optimization). The polypeptides that can be generated according to the methods of the invention are highly variable, and they can include antibodies and fusion proteins that contain an Fc region or a biologically active portion thereof. | 01-05-2012 |
20120244163 | BISPECIFIC BINDING AGENTS TARGETING IGF-1R AND ERBB3 SIGNALLING AND USES THEREOF - Disclosed are bispecific binding agents that specifically target both of the IGF-1 and the ErbB intracellular signaling pathways. For example, bispecific binding agents that comprise an anti-IGF-1R antibody and an anti-ErbB3 antibody connected by a linker are described herein. These bispecific agents are capable of antagonizing signal transduction by both of the IGF-1 and the ErbB signaling pathways and are useful in inhibiting the proliferation of tumor cells whose growth involves the signaling activity of both pathways. | 09-27-2012 |

Exemplary antibodies inhibit signal transduction through either or both of IGF-1R and ErbB3. Exemplary polyvalent proteins comprise at least one anti-IGF-1R binding site and at least one anti-ErbB3 binding site. In certain embodiments the binding sites may be linked through an immunoglobulin constant region. Novel antiErbB3 and anti-IGF-1R antibodies (e.g., monoclonal antibodies) are also provided. | 10-25-2012 |
