The present invention relates to antibodies, e.g., full length antibodies or antigen binding fragments thereof, that specifically bind to BCMA (B-Cell Maturation Antigen) and/or CD3 (Cluster of Differentiation 3). The invention also relates to antibody conjugates (e.g., antibody-drug-conjugates) comprising the BCMA antibodies, compositions comprising the BCMA antibodies, and methods of using the BCMA antibodies and their conjugates for treating conditions associated with cells expressing BCMA (e.g., cancer or autoimmune disease). The invention further relates to heteromultimeric antibodies that specifically bind to CD3 and a tumor cell antigen, (e.g., bispecific antibodies that specifically bind to CD3 and BCMA). Compositions comprising such heteromultimeric antibodies, methods for producing and purifying such heterodimeric antibodies, and their use in diagnostics and therapeutics are also provided.

The invention generally relates to methods and compositions for the prediction of therapeutic efficacy of cancer treatments and the prognosis of cancer. The invention discloses markers that are associated with favorable and unfavorable outcomes, respectively, in certain cancer treatments and are useful as prognostic markers for cancer. Methods involving these markers are disclosed for predicting cancer therapy benefit and prognosing clinical outcome for cancer patients.

Described herein are protein steroid conjugates that are useful, for example, for the target-specific delivery of glucocorticoids (GCs) to cells.

The disclosure relates to a method of treating cancer by administering to the subject a therapeutically effective amount of a composition comprising pyrvinium pamoate, optionally in combination with at least one additional therapeutic agent or modality.

The present invention relates to a one-pot process for preparing intermediate of antibody-drug conjugate. The preparation process provided by the present invention is simple in operation, and needs no such steps like concentration, washing and filtration of the intermediate reaction liquid, disposal of the organic waste liquid, and packaging and storage of the intermediate. The entire reaction system comprises only one separation and purification treatment, saving costs for labor, equipment, venues, raw materials, etc., and greatly reducing the pollution to the environment. In addition, the one-pot process for preparing intermediate of antibody-drug conjugate of the present invention produces the intermediate of antibody-drug conjugate with higher yield. The one-pot process for preparing intermediate of antibody-drug conjugate provided by the present invention is more suitable for scale-up production.

Methods for using anti-LIV1 antibodies and antibody-drug conjugates, including anti-LIV1 antibody-drug conjugates, to inhibit proliferation of a cell, such as a LIV1-expressing cell, as well as for the treatment of cancers, such as, e.g., LIV1-associated solid tumors and breast cancer (e.g., locally advanced or metastatic breast cancer), are provided.

The present invention relates to an antibody against delta-like 1 homolog (Drosophila) (DLK1) or an antigen-binding fragment thereof, a nucleic acid encoding the same, a vector comprising the nucleic acid, a cell transformed with the vector, a method for producing the antibody or an antigen-binding fragment thereof, an antibody drug conjugate (ADC) comprising the same, a pharmaceutical composition for treating cancer, a composition for diagnosing cancer, and a chimeric antigen receptor (CAR) and a T-cell engager comprising the same.

The present invention relates to antibody drug conjugates (ADCs) presenting improved properties of in vivo tolerability.

Disclosed herein, is a bi-functional allosteric protein-drug molecule comprising a targeting moiety, one or more biological binding domains, and one or more therapeutic agents, wherein the therapeutic agent is allosterically bound to the biological binding domain. Also described herein, are methods of incorporating a bi-functional allosteric protein-drug molecule comprising a targeting moiety, one or more biological binding domains that captures the therapeutic agent without the formation of a chemical bond, and one or more therapeutic agents; physiologically acceptable compositions including them; and methods of administering the bi-functional allosteric protein-drug molecule to patients for the treatment of cancer.

There is disclosed an improved ADC (antibody drug conjugate) type composition having at least two different drug payloads conjugated to a single targeting protein. More specifically, the present disclosure attaches a first drug conjugate to a dual Cysteine residue on a targeting protein and a second drug conjugate with a different drug to a Lys residue on the targeting protein.
