The present invention provide anti-human IL6 monoclonal antibodies, amino acid sequences of the variable region of the heavy chain and of the variable region of the light chain thereof, and encoding nucleotide sequences thereof. The present invention also provides a method for preparing the anti-human IL6 monoclonal antibodies and use of the anti-human IL6 monoclonal antibodies in the preparation of an antitumor drug. The present anti-human IL6 monoclonal antibodies can inhibit cell proliferation by blocking an IL6 signal pathway, thereby achieving the purpose of tumor immunotherapy.

The present disclosure provides isolated, engineered, non-naturally occurring CB1 binding proteins, including anti-CB1 antibodies or antigen-binding fragment thereof. The CB1 binding proteins find utility in the treatment and diagnosis of CB1 mediated conditions, diseases and disorders.

Provided herein are B7-H3 antibodies, fragments of such antibodies, and compositions comprising the same. The antibodies, antibody fragments and compositions are useful in a number of analytical methods, including immunohistochemical and immunocytochemical detection and analysis of B7-H3. Also provided herein are isolated peptides and fusion proteins containing immunogenic determinants for said B7-H3 antibodies, animals immunized with the peptides and fusion proteins, isolated B cells obtained from the animals, and hybridomas made from the isolated B cells.

An object of the present invention is to provide an anticancer drug capable of treating cancer by finding a target molecule specifically expressed in cancer cells and by specifically acting on the target molecule, and to provide a cancer testing method including a step of measuring the target molecule in a sample. The present invention provides an anticancer drug containing, as an active ingredient thereof, an anti-transmembrane protein 180 (TMEM-180) antibody or an antigen-binding fragment thereof. In addition, the present invention provides a cancer testing method including a step of measuring the amount of TMEM-180 in a sample collected from a subject.

The present disclosure is directed to antibodies binding to PD-L1 and methods of using such antibodies to treat cancers, such as those that express or overexpress PD-L1.

An antibody or antibody fragment that binds to complement protein C7 in isolation or as part of a protein complex and the various uses, for example for the treatment of a disease associated with the dysregulation of complement in a subject.

The present disclosure relates to an IL-33 antagonist for use in the prevention or treatment of abnormal epithelium physiology or EGFR-mediated diseases, and corresponding methods of prevention or treatment comprising administering an IL-33 antagonist to a patient in need thereof.

Disclosed are monoclonal antibodies and antigen binding fragments that specifically bind epidermal growth factor receptor (EGFR) variant (v) III, conjugates thereof, and chimeric antigen receptors. Nucleic acid molecules encoding the heavy and light chain domains of the antibodies, and the chimeric antigen receptors (CARs), are also disclosed, as are host cells expressing the nucleic acid molecules. In addition, disclosed is the use of these monoclonal antibodies, antigen binding fragments, conjugates, and T cells expressing the CARs, such as for the treatment of a tumor expressing EGFRvIII. Also disclosed are methods for detecting a tumor that expresses EGFRvIII.

Provided herein are methods and compositions for treating a subject suffering from a deficiency in α-L-Iduronidase in the CNS. The methods include systemic administration of a bifunctional fusion antibody comprising an antibody to a human insulin receptor and an α-L-Iduronidase. A therapeutically effective systemic dose is based on the specific CNS uptake characteristics of human insulin receptor antibody-α-L-Iduronidase fusion antibodies as described herein.

Antibody drug conjugates (ADCs) comprising an antibody conjugated to an anti-inflammatory therapeutic agent via a phosphate-based linker with tunable extracellular and intracellular stability are described.
