The present invention relates to immunoglobulins that bind IgE and FcγRIIb with high affinity, said compositions being capable of inhibiting cells that express membrane-anchored IgE. Such compositions are useful for treating IgE-mediated disorders, including allergies and asthma.

The invention provides bispecific fusion proteins that inhibit activation of complement pathway and vascular endothelial growth factor (VEGF) pathway and methods for using these fusion proteins.

The present invention relates to novel antibodies and fragments thereof that binds cannabinoid 1 (CB1) receptor. The antibodies and fragments thereof as disclosed herein include humanized antibodies that bind CB1 receptor. The invention also includes uses of the antibodies for treating a disease or disorder responsive to antagonism or agonism of the CB1 receptor.

This invention relates generally to molecules that specifically engage 41BB, a member of the TNF receptor superfamily (TNFRSF). More specifically, this invention relates to multivalent and multispecific molecules that bind at least 41BB.

The invention relates to human targets of interest (TOI), anti-TOI ligands, kits compositions and method.

The present invention provides methods of testing anti-STn antibodies for their ability target cancer stem cells by isolating cancer stem cells from cultures, contacting them with anti-STn antibodies being tested, and measuring resulting cell viability.

The disclosure relates inter alia to an Fc multimer composition, an Fc multimer composition comprising the Fc multimer composition of the invention in lyophilized form, as well as an Fc multimer composition according to the invention for use in the treatment of an autoimmune disease or an inflammatory disease.

Provided are an anti-VEGFA-anti-PD-1 bispecific antibody and a use thereof. Specifically, the anti-VEGFA-anti-PD-1 bispecific antibody comprises: a PD-1-targeted first protein functional region and a VEGFA-targeted second protein functional region. According to an EU numbering system, mutation occurs at two positions of positions 234 and 235 of a heavy chain constant region of the immunoglobulin contained in the bispecific antibody, and after the mutation, an affinity constant of the bispecific antibody with FcγRI, FcγRIIa, FcγRIIIa, and/or C1q is decreased compared to that before the mutation. The bispecific antibody can specifically bind to VEGFA and PD-1, specifically relieve immunosuppression of VEGFA and PD-1 on an organism, and inhibit tumor-induced angiogenesis, and thus has good application prospects.

Disclosed herein are methods of treating HNSCC that comprises administration of a HER3 blocker and an immune checkpoint modulator. In some embodiments, also disclosed herein is a method of modulating activity level of the PI3K/AKT/mTOR pathway in a HNSCC cell to modulate proliferation or sensitization of the cancer cell to a treatment therapy.

Provided herein are antibody conjugates with binding specificity for CD74 and compositions comprising the antibody conjugates, including pharmaceutical compositions, methods of producing the conjugates, and methods of using the conjugates and compositions for therapy.
