The invention provides antagonistic antibodies to BACE1 and methods of using the same for the treatment of neurological disease and disorders.

The present invention relates to an anthracycline (PNU) derivative conjugate comprising a derivative of the anthracycline PNU-159682 having the formula (i) or formula (ii) which further comprises a linker structure X-L1-L2-L3-Y.

Linker-drug compounds and antibody-drug conjugates that bind to human oncology targets are disclosed. The linker-drug compounds and antibody-drug conjugates comprise a splicing modulator drug moiety. The disclosure further relates to methods and compositions for use in the treatment of neoplastic disorders by administering the antibody-drug conjugates provided herein. In an embodiment, the splicing modulator comprises a pladienolide or a pladienolide derivative.

Provided herein are modified amino acids comprising a tetrazine groups according to Formula I: polypeptides, antibodies, payloads and conjugates comprising these modified amino acid residues derived from the modified amino acids, and methods of producing the polypeptides, antibodies, payloads and conjugates comprising the modified amino acid residues. The polypeptides, antibodies, payloads and conjugates are useful in methods of treatment and prevention, methods of detection and methods of diagnosis. ##STR00001##

Compositions and methods for treating a viral infection may comprise use of a nanoparticle composition. A nanoparticle composition of the present disclosure may comprise a targeting moiety and/or anti-viral agent and reduces the infectivity of a virus for a host cell. A method of treating a viral infection may comprise administering a composition comprising a nanoparticle of the present disclosure, to a subject and reducing the infectivity of the virus for a host cell of the subject. The compositions may be administered via intranasal or systemic administration to treat or prevent a viral infection, for example a coronavirus infection.

Provided is an antibody that recognizes and binds to carbonic anhydrase or antigen-binding fragment, a nucleic acid molecule coding for the antibody or antigen-binding fragment, a vector carrying the nucleic acid molecule, a host cell including the nucleic acid molecule or the vector, and use of the antibody or antigen-binding fragment thereof in the alleviation, prevention, treatment or diagnosis of solid cancers.

The present disclosure relates generally to anti-CD39 antibodies, including antibody-drug conjugates comprising the antibodies, and methods of their use.

The present disclosure provides a compound having a STING agonistic activity, which may be expected to be useful as an agent for the prophylaxis or treatment of STING-related diseases. The present disclosure relates to a compound represented by the formula (I): ##STR00001##
wherein each symbol is as defined in the description, or a salt thereof.

Disclosed is a solid phase method of synthesizing biomolecule-drug-conjugates. In particular, this invention relates to a solid phase method of synthesizing antibody-drug-conjugates (ADCs). This invention also relates to intermediate methods of producing immobilized, chemically modified biomolecules, e.g., antibodies.

Described herein are materials and methods for treating subjects having a HER-3 associated disease, by administering a first agent that binds to HER-3, in combination with a second agent that binds and/or inhibits another member of the HER family. The first and the second agent may be a biologic, such as an antigen-binding protein, or a small molecular tyrosine kinase inhibitor, for example.
