The present disclosure relates generally to cysteine engineered antibody-drug conjugates comprising peptide-containing linkers and to methods of using these conjugates as therapeutics and/or diagnostics.

The present invention relates to the conjugates of Tubulysin derivatives (anologs) and cell-binding molecules using branched (side-chain) linkers, and the resulting conjugates have better pharmacokinetic properties, and thus can more accurately target and kill abnormal cells. The invention also relates to the conjugation methods of the Tubulysin derivatives (anologs) to cell-binding molecules, and methods for synthesizing the small molecules, and methods of using the conjugates for targeted therapy for cancers, infections and autoimmune diseases. The conjugates of Tubulysin derivatives with long branched linkers demonstrated increased half-life, minimal exposure to non-targeted cells, tissues or organs in system circulation, leading to reduced off-target toxicity.

This invention relates to anti-ROR1 antibodies and methods of using them in treating diseases and conditions related to ROR1 activity, e.g., cancer.

Provided herein are methods for the treatment of cancers with antibody drug conjugates (ADC) that bind to 191P4D12 proteins. Also provided herein are methods for the treatment of urothelial cancer using an antibody drug conjugate (ADC) that binds 191P4D12. Additionally provided herein are methods for the treatment of solid tumors using an antibody drug conjugate (ADC) that binds 191P4DI2.

Provided herein are antibody conjugates with binding specificity for CD74 and compositions comprising the antibody conjugates, including pharmaceutical compositions, methods of producing the conjugates, and methods of using the conjugates and compositions for therapy.

The present invention provides compositions for the production of an antibody or functional fragment thereof directed against Tn antigen or sTn antigen. The compositions disclosed herein include isolated antibody or functional fragments thereof that binds to Tn antigen or sTn antigen and polynucleotides encoding the heavy chain and/or a light chain variable domains of such antibody or functional fragment. The invention also provides methods of treating or preventing a disease, such as cancer or tumor formation, wherein the antibody or functional fragment includes a variable heavy chain domain and a variable light chain domain that has an amino acid sequence provided herein. The invention further provides a conjugate of an antibody or functional fragment thereof conjugated or recombinantly fused to a localizing agent, detectable agent or therapeutic agent, and methods of treating, preventing or diagnosing a disease in a subject in need thereof.

The present invention relates to new antibody-drug conjugates (ADCs) targeting ROR1, active metabolites of such ADCs, methods for preparation of such ADCs, uses for such ADCs in treatment and/or prevention of illnesses, and uses for such ADCs in production of drugs for treatment and/or prevention of diseases, more specifically diseases associated with over-expression of ROR1, for example cancer. More specifically, the present invention relates to an antibody-drug conjugate comprising an antibody that binds to ROR1 or an antigen-binding fragment thereof, and a pharmaceutical composition comprising the same.

The present disclosure provides methods comprising administering to the individual an effective amount of an agent that decreases or inhibits TIGIT expression and/or activity and an anti-cancer agent and/or an anti-cancer therapy. Further provided are kits comprising an anti-cancer agent, an agent that decreases or inhibits TIGIT expression and/or activity, or both, as well as instructions for use thereof.

It is an object of the present invention to provide an antibody binding to CDH6 and having internalization activity, an antibody-drug conjugate of the antibody and a drug having antitumor activity, a pharmaceutical product comprising the antibody-drug conjugate and having therapeutic effects on a tumor, a method for treating a tumor using the antibody, the antibody-drug conjugate or the pharmaceutical product, and the like. The present invention provides an anti-CDH6 antibody having internalization activity, an antibody-drug conjugate of the antibody and a drug having antitumor activity, a pharmaceutical product comprising the antibody or the antibody-drug conjugate, and a method for treating a tumor.

Novel neoantigen-eliciting antibody drug conjugates are disclosed. These compounds or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof are useful for the treatment of disorders, including but not limited to pancreatic cancer and other check point positive cancers. More particularly, these compounds may comprise biologically active polypeptides or hormones modified to include the attachment of therapeutic compounds using linkers. The compounds of the disclosure, or pharmaceutically acceptable salts, hydrates, solvates, isomers, or tautomers thereof, also comprise therapeutic compounds connected to linkers.
