The invention relates to novel benzodiazepine derivatives with antiproliferative activity and more specifically to novel benzodiazepine compounds of formula (I)-(VII). The invention also provides conjugates of the benzodiazepine compounds linked to a cell-binding agent. The invention further provides compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal using the compounds or conjugates of the invention.

The invention generally relates to antibodies that bind to human folate receptor 1 and diagnostic assays for folate receptor 1-based therapies. Methods of using the antibodies to monitor therapy are further provided.

The present invention relates to anti-transferrin receptor antibodies and methods of their use.

The present invention provides antibodies and related molecules that bind to chemokine receptor 4 (CXCR4). The invention further provides antibody-drug conjugates comprising such antibodies, antibody encoding nucleic acids, and methods of obtaining such antibodies. The invention further relates to therapeutic methods for use of these antibodies and anti-CXCR4 antibody-drug conjugates for the treatment of a disorder associated with CXCR4 function or expression (e.g., cancer), such as colon, RCC, esophageal, gastric, head and neck, lung, ovarian, pancreatic cancer or hematological cancers.

Methods and compositions for treating a urothelial and/or a micropapillary carcinoma, such as a micropapillary urothelial carcinoma are disclosed.

Provided herein are antibodies, or antigen binding portions thereof, that bind to glucocorticoid-inducible TNF receptor (GITR). Also provided are uses of these proteins in therapeutic applications, such as in the treatment of cancer. Further provided are cells that produce the antibodies, polynucleotides encoding the heavy and/or light chain variable region of the antibodies, and vectors comprising the polynucleotides encoding the heavy and/or light chain variable region of the antibodies.

The present invention relates to antibodies that bind to receptors expressed on the blood brain barrier and methods of using the same.

Pharmaceutical compositions comprising antibody-urease conjugates and substantially free of unconjugated urease are disclosed. These compositions are prepared by a method that does not require chromatographic purification. These pharmaceutical compositions have utility in the treatment of cancer by antibody-directed enzyme prodrug therapy wherein the urease converts endogenous urea into ammonia in situ to induce cytotoxicity.

The invention provides anti-CLL-1 antibodies and immunoconjugates and methods of using the same.

Disclosed are compounds and compositions for the activation or induction of expression of a pattern recognition receptor (e.g., STING, RIG-I, MDA5), and methods of use thereof.
