Methods for treating coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, is described. The methods can be used to reduce the severity of outcomes related to COVID-19, such as hospitalization and ventilation. For example, treatment of a subject with a therapeutic agent that neutralizes interleukin 13 (IL-13) can result in reduced risk for mechanical ventilation in the subject. Also described are methods of predicting risk of mechanical ventilation in subjects with COVID-19.

Methods of treating cancer with antibodies that bind colony stimulating factor 1 receptor (CSF1R) in combination with one or more immune stimulating agents are provided.

New clinical uses of anti-CD127 agents, in particular anti-CD127 antibodies or related compounds for the treatment and/or the prevention of cancer. Methods for treating a patient having a CD127-positive cancer are provided, in particular a CD127-positive leukemia or a CD127-positive solid tumor, by administering to the patient a therapeutic dose of an anti-CD127 agent, the anti-CD127 agent having the capability to enhance the Antibody Dependent Cellular Phagocytosis (ADCP) activity of macrophages targeting CD127-positive cancer cells, and not having Antibody Dependent Cytotoxic Activity (ADCC), in particular against immune cells, more particularly against T cells.

Disclosed are compositions comprising an isolated chimeric interleukin 6 receptor alpha (IL-6Rα) binding protein or cells expressing an isolated chimeric IL-6Rα binding protein. The isolated IL-6Rα chimeric binding protein and cells expressing the protein may be used in methods of treating cancer and reducing the risk of cytokine release syndrome.

The present disclosure relates to an engineered antibody that co-engages a cell type-selective (or specific) antigen (guide) and a signaling receptor (effector) on a target cell. In some instances, the engineered antibody is capable of modulating a signaling pathway on a target cell. In other embodiments, an engineered antibody of the present disclosure is administered to a subject for the treatment of a disease or condition.

Disclosed are antigen binding polypeptides and antigen binding polypeptide complexes (e.g., antibodies and antigen binding fragments thereof) having certain structural features. Also disclosed are polynucleotides and vectors encoding such polypeptides and polypeptide complexes; host cells; chimeric antigen receptors (CARs); immune cells; pharmaceutical compositions and kits containing such polypeptides and polypeptide complexes; and methods of using such polypeptides and polypeptide complexes.

Therapeutic combinations of immunoconjugates that bind to CD123 (e.g., IMGN632) with BCL-2 inhibitors (e.g., venetoclax), and/or a hypomethylating agent (e.g., azacitidine or decitabine) are provided. Methods of administering the combinations to treat hematological malignancies with clinical efficacy and/or decreased toxicity are also provided. Methods of treating hematological malignances present as minimal residual disease using immunoconjugates that bind to CD123 (e.g., IMGN632) are also provided.

Provided herein engineered polypeptides that comprise a combination of spatially-associated topological constraints, wherein at least one constraint is derived from a CD25 reference target, and methods of selecting said engineered polypeptides. Further provided are methods of using the engineered polypeptides, including as positive and/or negative selection molecules in methods of screening a library of binding molecules such as antibodies. Further provided herein are CD25 antibodies selected using these engineered polypeptides.

Provided herein are antibodies that specifically bind to CD25. Also provided herein are methods of making the antibodies described, and methods of use thereof. For example, the CD25 antibodies may be used therapeutically to treat cancer or autoimmune diseases.

Provided are an anti-ST2 antibody or a fragment thereof. The antibody or the fragment thereof can be specifically bound to human ST2, for inhibiting combination of IL-33 and human ST2, blocking an IL-33/ST2 intracellular signaling pathway, and inhibiting the promoting effect of different forms of IL-33 in cell-derived IL5, IL6 and 118 production. Compared with a known anti-ST2 antibody, this anti-ST2 antibody has higher biological activity, and can be used for preventing, treating or alleviating diseases related to ST2 expression or IL-33/ST2 pathway disorders.
