The present invention provides a combination therapy for treating a tumor in a subject. The combination comprises two elements. The first is a polypeptide construct comprising an attenuated Type 1 interferon (IFN) linked to an antibody which binds to a cell surface-associated antigen expressed on the tumour cell and comprising a functional Fc region. The second is a CD47 antagonist which inhibits the interaction CD47 with the SIRPα receptor.

Provided are anti-PD-L1 antibodies, variants, mutants, and antigen binding fragments thereof. Also provided are isolated nucleic acid molecules that encode the anti-PD-L1 antibodies, variants, mutants, or antigen binding fragments thereof, and related expression vectors, and host cells. Provided are methods of making anti-PD-L1 antibodies, variants, mutants, and antigen binding fragments thereof. Also provided are related pharmaceutical compositions and methods of their use to treat subjects. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The present disclosure relates to methods for treating or preventing immune-mediated pulmonary injury (IMPI) in a subject in need thereof, the method comprising administering to the subject an anti-Type I interferon (anti-T1i) therapy that blocks the activity, function or production of Type I interferon (T1i) in the subject, wherein the anti-T1i therapy is administered to the subject infected with a respiratory virus that causes a delayed T1i response in the subject.

A method of treating skin diseases by administering a pharmaceutical composition including a humanized antibody which binds to vimentin.

Provided are an anti-PD-L1 antibody, and a preparation method therefor and an application thereof. The antibody is obtained by a computer-aided design, and the anti-PD-L1 antibody comprises an antibody I and/or an antibody II; an antibody sequence is subjected to simulation analysis and design by bioinformatics modeling without complicated and cumbersome immune reactions; the antibody is designed and transferred into a host cell by molecular biological construction, and expressed in the host cell and purified to obtain the antibody with a PD-L1 antigen binding activity.

An antigen-binding molecule comprising a first antigen-binding moiety that is capable of binding to CD3 and CD137 (4-1BB), but does not bind to CD3 and CD137 at the same time (i.e. dual-binding to CD3 and CD137 but not simultaneously); and a second antigen-binding moiety capable of binding to a molecule specifically expressed in a cancer tissue, specifically Glypican-3 (GPC3) is provided. Due to the dual binding to CD3 and CD137 but not simultaneously and with fine-tuned binding kinetics, and the binding to GPC3, the multispecific antigen-binding molecule express strong cytotoxic activity for cancer cells with reduced adverse effects. Further, by adapting antibody engineering technologies and a molecular format design (including charged mutations in the framework region and/or constant region, VH/VL exchanged, and Fc region selection), the multispecific antigen-binding molecule with favorable stability, manufacturability/producibility and structural homogeneity is provided.

The present disclosure provides anti-CCR8 antibodies, including compositions and methods of using such antibodies.

Disclosed herein are humanized antibodies, antigen-binding fragments thereof, and antibody conjugates, that are capable of specifically binding to certain biantennary Lewis antigens, which antigens are expressed in a variety of cancers. The presently disclosed antibodies are useful to target antigen-expressing cells for treatment or detection of disease, including various cancers. Also provided are polynucleotides, vectors, and host cells for producing the disclosed antibodies and antigen-binding fragments thereof. Pharmaceutical compositions, methods of treatment and detection, and uses of the antibodies, antigen-binding fragments, antibody conjugates, and compositions are also provided.

The present invention concerns antigen binding proteins and fragments thereof which specifically bind B Cell Maturation Antigen (BCMA), particularly human BCMA (hBCMA) and which inhibit the binding of BAFF and APRIL to the BCMA receptor. Further disclosed are pharmaceutical compositions, screening and medical treatment methods.

The present invention provides antigen-binding molecules containing (i) an antigen-binding domain whose antigen-binding activity varies depending on ion concentration conditions, (ii) an FcγR-binding domain having Fcγ RIIb-selective binding activity, and (iii) an FcRn-binding domain having FcRn-binding activity under an acidic pH range condition, and methods of decreasing plasma antigen concentration as compared to before administering the molecule, which include the step of administering the molecule.
