The present invention relates to an antibody-drug-conjugate. From one aspect, the invention relates to an anti-body-drug-conjugate comprising an antibody capable of binding to a Target, said antibody being conjugated to at least one drag selected from derivatives of dolastatin 10 and auristatins. The invention also comprises method of treatment and the use of said anti-body-drag-conjugate for the treatment of cancer.

Anti-HER2 biparatopic antibody-drug conjugates (ADCs) in which the drug is an auristatin analogue and is conjugated to the antibody at a low average drug-to-antibody ratio (DAR), and methods of using the ADCs in the treatment of a HER2-expressing cancer. The low average DAR (<3.9) ADCs as described herein have improved tolerability and decreased toxicity as compared to a corresponding ADC having a DAR ≥3.9 when administered at the same toxin dose.

The invention provides an immunoconjugate of formula:

##STR00001##

or pharmaceutically acceptable salt thereof, wherein subscript r is an integer from 1 to 10, subscript n is an integer from about 2 to about 25, and “Ab” is an antibody construct that has an antigen binding domain that binds HER2. The invention further provides compositions comprising and methods of treating cancer with the immunoconjugate.

In some aspects, the invention relates to an antibody-drug conjugate, comprising an antibody; a linker; and at least two active agents. In preferred embodiments, the linker comprises a peptide sequence of a plurality of amino acids, and at least two of the active agents are covalently coupled to side chains of the amino acids. The antibody-drug conjugate may comprise a self-immolative group, preferably two-self-immolative groups. The linker may comprise an O-substituted oxime, e.g., wherein the oxygen atom of the oxime is substituted with a group that covalently links the oxime to the active agent; and the carbon atom of the oxime is substituted with a group that covalently links the oxime to the antibody.

The present invention relates to compounds for targeted immunotherapy, as well as compositions comprising the same. Further, the present invention relates to the use of the compounds in the treatment of HER2 positive tumors/cancers.

Described and provided herein are novel antibodies for Claudin 18.2. Also described and provided are pharmaceutical compositions of the antibodies and methods of use for the treatment of cancer.

The invention provides methods or compositions for treating cancer using a superantigen conjugate in combination with a B-cell depleting agent, e.g., an anti-CD20 antibody.

The disclosure relates to a compound of formula (I):

##STR00001## wherein X, A, Y and X.sub.1 are as defined in the description.

The disclosure also relates to a conjugate between a protein comprising at least two disulfide bridges and a compound of formula (I).

This invention relates to antibody-albumin nanoparticle complexes comprising albumin, an antibody with binding specificity for a cancer antigen (e.g. panitumumab), and paclitaxel, wherein the nanoparticle complex has been pre-formed in vitro such that the nanoparticle complex has antigen-binding specificity (e.g. EGFR binding specificity), for the purpose of providing cancer (e.g. EGFR-related cancer) treatments in a subject in need thereof.

The present invention provides for recombinant monoclonal antibodies that bind to human colorectal and pancreatic carcinoma-associated antigens, along with nucleic acid sequences encoding the antibody chains, and the amino acid sequences corresponding to the nucleic acids, and uses for these antibodies, nucleic acids and amino acids.
