  • Publication number: 20170137500
    Abstract: Processes for producing and purifying recombinant proteins are disclosed. In particular, the present disclosure provides processes of producing and purifying multi-subunit proteins expressed in yeast or filamentous fungal cells. The production and/or purification of such proteins are monitored for impurities, preferably using lectin binding assays, such that one or more process parameters may be adjusted to maximize the amount of desired recombinant protein and minimize the amount of glycosylated impurities. The processes can also be monitored for other undesired product-associated impurities, such as aggregates and nucleic acids. In exemplary embodiments, the recombinant proteins are multi-subunit proteins, such as antibodies, the host cell is a yeast, such as Pichia pastoris, and the glycosylated impurity is a glycovariant of the desired recombinant polypeptide, such as an N-linked and/or O-linked glycovariant.

  • Publication number: 20170051048
    Abstract: This invention pertains to NGF antagonists including antibodies and fragments thereof (including Fab fragments) having binding specificity to human Nerve Growth Factor (hereinafter “NGF”), and methods of using one or more of said antibodies and fragments thereof to treat pain in an individual. More specifically the invention relates to methods of treating pain or eliciting an analgesic effect in an individual, comprising administering an effective amount of an NGF antagonist, e.g., an anti-human NGF antibody or fragment thereof or another moiety, such as a nucleic acid or polypeptide such as a fragment of NGF or TrkA which inhibits the association of NGF with TrkA, without appreciably inhibiting the association of NGF with p75. These methods may optionally further include administering an effective amount of a second anti-human NGF antibody or fragment thereof which inhibits the association of NGF with p75, that may further also inhibit the association of NGF with TrkA.

  • Publication number: 20160362488
    Abstract: The present invention is directed to antagonistic antibodies and antigen binding fragments thereof having binding specificity for PACAP. These antibodies inhibit, block or neutralize at least one biological effect associated with PACAP, e.g., vasodilation. In exemplary embodiments these antibodies and antigen binding fragments thereof may comprise specific VH, VL, and CDR polypeptides described herein. In some embodiments these antibodies and antigen binding fragments thereof bind to and/or compete for binding to specific epitope(s) on human PACAP. The invention is further directed to using these antagonistic anti-PACAP antibodies, and binding fragments thereof, for the diagnosis, assessment, and treatment of diseases and disorders associated with PACAP and conditions where antagonism of PACAP-related activities, such as vasodilation, mast cell degranulation, and/or neuronal activation, are therapeutically beneficial, e.g., headache and migraine indications.

  • Publication number: 20160033504
    Abstract: Methods of identifying antigen-specific antibody-secreting and antibody-forming cells, such as antigen-specific B cells, and methods for cloning the antigen-specific antibody sequences of the antibody produced by these cells are provided. In particular, the methods include enriching B cells for antigen-specific B cells, culturing the antigen-specific B cells to generate clonal B cell populations, detecting clonal B cells that produce a single antigen-specific antibody, optionally screening the clonal B cell populations for functional activity, staining and sorting the cells to isolate the antigen-specific B cells, sequencing the nucleic acids encoding the antigen-specific antibody sequences, expressing the sequences to produce an antibody, isolating the antibody and screening the antibody for antigen recognition. The methods provide improved enrichment and selection of antigen-specific antibody-secreting and antibody-forming cells, which enhances recovery of antigen-specific antibodies.
