Provided are an anti-CLDN18.2 antibody or an antigen-binding fragment thereof, a derivative comprising said antibody or antigen-binding fragment thereof, a pharmaceutical composition, and related use of said antibody or antigen-binding fragment thereof for treating, diagnosing and detecting cancers.

An antitumor pharmaceutical camptothecin derivative and an antibody-drug conjugate thereof. By means of a series of molecular structure modifications, an optimal camptothecin antitumor drug is obtained, so as to be more suitable as a drug for antibody conjugation.

The present disclosure relates to methods of using antibody conjugates with binding specificity for BCMA (BCMA) and its isoforms and homologs in combination with a gamma secretase inhibitor (GSI), such as in therapeutic methods. Also provided are pharmaceutical compositions and kits comprising the antibody conjugates and GSI.

Provided herein are poly-1-hydroxymethylethylene hydroxymethyl formal (PHF)-based drug delivery systems. Also disclosed are methods of making antibody-drug conjugates and methods of treatment using these conjugates.

Disclosed herein are polynucleic acid molecules, pharmaceutical compositions, and methods for treating Facioscapulohumeral muscular dystrophy.

The present disclosure relates to anti-CDCP1 antibodies, and antigen binding fragments thereof that specifically bind to the full length and cleaved forms CUB domain-containing protein 1 (CDCP1), and conjugates comprising anti-CDCP1 antibodies and uses thereof for treatment and detection of cancer.

Aspects of the disclosure relate to methods and compositions useful for in vivo and/or in vitro enzyme profiling. In some embodiments, the disclosure provides methods of in vivo enzymatic processing of exogenous molecules followed by detection of signature molecules as representative of the presence of active enzymes associated with diseases or conditions. In some embodiments, the disclosure provides compositions and in vitro methods for localization of enzymatic activity in a tissue sample.

The present invention relates to novel linkers containing a 2,3-disubstituted succinic group, or 2-monosubstituted, or 2,3-disubstituted fumaric or maleic (trans (E)- or cis (Z)-butenedioic), or acetylenedicarboxyl group for conjugation of a cytotoxic agent, and/or one or more different functional molecules per linker to a cell-binding molecule, through bridge linking pairs of thiols on the cell-binding molecule specifically. The invention also relates to methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.

Provided are activatable proprotein homodimers, comprising at least two separate polypeptide chains, each chain comprising an IL-2 protein variant that has reduced binding affinity to wild-type IL-2Rα relative to that of the wild-type IL-2 sequence, a cleavable linker, and an IL-2 binding protein, among other optional features, and related pharmaceutical compositions and methods of use thereof.

The present disclosure provides scaffolds and antibody-drug conjugates (ADCs) comprising a stimulator of interferon genes (STING). The present disclosure also provides uses of the ADCs in treatment, e.g., treatment of cancer.
