The present invention relates to anti-CLL-1 antibodies including anti-CLL-1 antibodies comprising a CLL-1 binding domain and a CD3 binding domain (e.g., anti-CLL-1/CD3 T cell dependent bispecific (TDB) antibody) and methods of using the same.

The invention provides, inter alia, methods of treating a disorder characterized by pathological activity of CD30+ cells, such as in certain solid, hematological and lymphoid cancers, in a non-adult human subject by administering an effective amount of an anti-CD30 ADC (antibody drug conjugate), such as, brentuximab vedotin, to the subject. The invention also provides corresponding kits and articles of manufacture suitable for performing the methods provided by the invention.

Provided herein are formulations of PCSK9-binding polypeptides, such as those comprising evolocumab, that comprise N-acetyl arginine and have reduced viscosities when compared to formulations lacking N-acetyl arginine. Provided herein are also methods of formulating such compositions that are advantageous in that they conserve certain components. Such formulations comprising PCSK9-binding polypeptides can be administered to patients to treat and/or prevent PCSK9-related diseases, conditions, and disorders.

The present invention is directed to heterodimeric antibodies that bind CD3 and PSMA.

Pharmaceutical compositions containing anti-beta amyloid (Aβ) antibodies or AD-binding fragments thereof are provided. These pharmaceutical compositions find use in the treatment of abnormal accumulation or deposition of Aβ in the central nervous system, mild cognitive impairment, and AD-associated disorders such as Alzheimer's disease.

Disclosed is a SIRPα-targeting antibody or an antigen-binding fragment thereof, comprising a light chain variable region and/or a heavy chain variable region. The antibody or the antigen-binding fragment thereof binds to human SIRPα-V1 and human SIRPα-V2, but weakly or does not bind to human SIRPβ and SIRPγ, does not bind to human T cells, and has the function of blocking the binding of SIRPα to CD47. Further disclosed are a bispecific antibody comprising same, a method for preparing the antibody or the antigen-binding fragment thereof and an application thereof. The unique properties of the disclosed antibody or the antigen-binding fragment thereof enable same to be more suitable for the development of drugs for an antibody or antigen-binding fragment against a human SIRPα target. As a candidate drug, same can be administered alone or in combination, providing a new or even better choice for the combined immunotherapy of tumors.

Provided herein are antigen-binding protein constructs capable of specifically binding DLL3 or an epitope of DLL3 presented on the surface of a target mammalian cell, wherein said antigen binding is pH-dependent. Provided are also uses of said antigen-binding protein constructs.

The present disclosure relates generally to methods of treating (i) a tumor (e.g., a solid tumor, an advanced solid tumor, a cancer), (ii) tumor-related weight loss, or (iii) tumor-related cachexia in a human patient, the method comprising administering to the human patient an anti-GDNF family receptor alpha-like (GFRAL) antibody, wherein the antibody inhibits GFRAL binding to Ret proto-oncogene (RET). The present disclosure also relates generally to methods of treating pancreatic cancer (e.g., an advanced pancreatic cancer, a metastatic pancreatic cancer, a pancreatic adenocarcinoma, a metastatic pancreatic adenocarcinoma, an MSI-H pancreatic cancer, a pancreatic ductal adenocarcinoma, a metastatic pancreatic ductal adenocarcinoma) in a human patient, comprising administering to the human patient (i) an anti-GFRAL antibody, wherein the antibody inhibits GFRAL binding to RET; (ii) paclitaxel; and (iii) gemcitabine.

Provided are compositions and methods for improving tumor penetrability of anti-tumor antibodies or conjugates thereof. The method comprises administering to an individual in need of treatment an anti-idiotypic antibody in addition to the anti-tumor antibody or conjugate. Examples are provided for anti-HER2 antibodies and anti-idiotypic antibodies that are directed to the anti-HER2 antibodies.

Methods are provided for using anti-CD47 mAbs as therapeutics for the prevention and treatment of solid and hematological cancers, with other anti-cancer agents, which include but are not limited to proteasome inhibitors, immunomodulatory agents, Bruton's tyrosine kinase (BTK) inhibitors, BCMA-targeting agents, CAR-T cells, anthracyclines, platinums, taxols, cyclophosphamides, topoisomerase inhibitors, anti-metabolites, anti-tumor antibiotics, mitotic inhibitors, alkylating agents, and demethylating agents.
