  • Patent number: 11236146
    Abstract: Disclosed is a stable pharmaceutical formulation, comprising a fusion protein in which the extracellular ligand-binding domain of a human p75 tumor necrosis factor receptor is fused to the Fc domain of human IgG and a succinate buffering agent, without comprising a stabilizer. The stable pharmaceutical formulation enables the long-term storage of the TNFR-Fc fusion protein formulation and can exhibit superior storage stability without the need for demanding storage conditions, and is a simple formulation because no stabilizer is comprised therein and is thus more economical than other stabilizer-comprising formulations.

  • Patent number: 9476045
    Abstract: The invention relates to iRNA agents, which preferably include a monomer in which the ribose moiety has been replaced by a moiety other than ribose that further includes a tether having one or more linking groups, in which at least one of the linking groups is a cleavable linking group. The tether in turn can be connected to a selected moiety, e.g., a ligand, e.g., a targeting or delivery moiety, or a moiety which alters a physical property. The cleavable linking group is one which is sufficiently stable outside the cell such that it allows targeting of a therapeutically beneficial amount of an iRNA agent (e.g., a single stranded or double stranded iRNA agent), coupled by way of the cleavable linking group to a targeting agent—to targets cells, but which upon entry into a target cell is cleaved to release the iRNA agent from the targeting agent.

    Abstract: The present invention concerns compositions and methods of use of a humanized Class III anti-CEA antibody, comprising the heavy and light amino acid sequences SEQ ID NO:1 and SEQ ID NO:2. The antibody is effective to treat CEACAM5-expressing tumors, either alone or in combination with one or more therapeutic agents. Drug conjugated Class III anti-CEA antibodies, such as SN-38 or P2PDox immunoconjugates, are particularly efficacious. Surprisingly, the antibody-drug conjugates (ADCs) exhibit high anti-cancer efficacy, while exhibiting low levels of systemic toxicity that are readily treated with standard amelioration techniques. Antibodies and/or immunoconjugates comprising the amino acid sequences SEQ ID NO:1 and SEQ ID NO:2 are surprisingly efficacious for therapy of solid tumors, even when the tumor has proven resistant to standard anti-cancer therapies.

  • Publication number: 20150111279
    Abstract: The present invention provides compositions and methods of use of humanized, chimeric or human Class I anti-CEA antibodies or fragments thereof, preferably comprising the light chain variable region CDR sequences SASSRVSYIH (SEQ ID NO:1); GTSTLAS (SEQ ID NO:2); and QQWSYNPPT (SEQ ID NO:3); and the heavy chain variable region CDR sequences DYYMS (SEQ ID NO:4); FIANKANGHTTDYSPSVKG (SEQ ID NO:5); and DMGIRWNFDV (SEQ ID NO:6). The Class I anti-CEA antibodies or fragments are useful for treating diseases, such as cancer, wherein the diseased cells express CEACAM5 and/or CEACAM6 antigens. The Class I anti-CEA antibodies or fragments are also of use for interfering with specific processes, such as metastasis, invasiveness and/or adhesion of cancer cells, or for enhancing sensitivity of cancer cells to cytotoxic agents and have favorable effects on the survival of subjects with cancer.

  • Publication number: 20150110793
    Abstract: The inventors successfully produced anti-Epiregulin antibodies showing cross-species reactivity between cynomolgus monkey (non-human animals) and human, anti-Epiregulin antibodies with suppressed chemical degradation, anti-Epiregulin antibodies with lowered isoelectric point, anti-Epiregulin antibodies with increased thermal denaturation midpoint temperature, and anti-Epiregulin antibodies with reduced amount of aggregate by performing appropriate amino acid residue substitutions in the variable-region sequences of the humanized EP27 antibody which inhibits growth of cancer cells by exhibiting cytotoxic activity and neutralizing activity against human Epiregulin-expressing cancer cells.
