A method of use of an isolated polypeptide conjugated with a radionuclide, wherein the isolated polypeptide binds specifically to HER2, or a variant thereof is described. The method is for monitoring the response to HSP90 inhibition and comprises the use of the isolated polypeptide conjugated with 18F. The application also describes the use of an isolated polypeptide conjugated with 18F, wherein the isolated polypeptide binds specifically to HER2 or variants thereof, as an imaging agent to monitor uptake thereof to measure HSP90 inhibition.

The present invention provides antibodies useful as therapeutics for treating and/or preventing diseases associated with cells expressing CLD18, including tumor-related diseases such as gastric cancer, esophageal cancer, pancreatic cancer, lung cancer, ovarian cancer, colon cancer, hepatic cancer, head-neck cancer, and cancer of the gallbladder.

This invention relates to NPC-1 antigen on the MUC5AC protein and 16C3 antigen on CEACAM5 and CEACAM6 proteins, and 31.1 epitope on the A33 protein are differentially expressed in cancers including, lung cancer, ovarian cancer, pancreas cancer, breast cancer, and colon cancer, and diagnostic and therapeutic usages. Further, NPC-1, 16C3, and/or 31.1 epitope specific antibodies and diagnostic and therapeutic methods of use.

Provided herein are antagonists or binding agents of an abnormal vasopressin receptor V.sub.2 (e.g., AbnV.sub.2), such as antibodies and antigen-binding portions thereof specific for the receptor, for identifying and targeting cancer cells expressing such abnormal vasopressin receptor V.sub.2. Additionally provided are methods of using said antagonists or binding agents, for example, to image cancer cells or in biological samples, or diagnose cancers, both in vivo and in vitro. The antagonists or binding agents may also be used for treating patients suffering from a cancer expressing the abnormal vasopressin receptor V.sub.2, such as small cell lung cancer (SCLC), breast cancer, or ovarian cancer.

The invention provides a method for the formation of a tissue-targeting thorium complex, said method comprising; a) forming an octadentate chelator comprising four hydroxypyridinone (HOPO) moieties, substituted in the N-position with a methyl group, and a coupling moiety terminating in a carboxylic acid group; b) coupling said octadentate chelator to at least one tissue-targeting moiety targeting HER2; and c) contacting said tissue-targeting chelator with an aqueous solution comprising an ion of at least one alpha-emitting thorium isotope. A method of treatment of a neoplastic or hyperplastic disease comprising admistration of such a tissue-targeting thorium complex, as well as the complex and corresponding pharmaceutical formulations are also provided

The present invention aims to provide a pharmaceutical composition for cancer treatment, which comprises a novel monoclonal antibody binding to SLC6A6 or its extracellular region and a chemotherapeutic agent conjugated therewith, as well as a therapeutic method in which the monoclonal antibody or a therapeutic agent composed of the monoclonal antibody conjugated with a chemotherapeutic agent is used in combination with a chemotherapeutic agent. The present invention provides a pharmaceutical composition comprising an antibody conjugate configured such that a monoclonal antibody having higher affinity than conventional antibodies and recognizing native SLC6A6 or a native polypeptide of an extracellular region of SLC6A6 is conjugated with an anticancer agent or the like having activity against cancer and other hyperproliferative diseases.

The present invention provides antibodies useful as therapeutics for treating and/or preventing diseases associated with cells expressing CLD18, including tumor-related diseases such as gastric cancer, esophageal cancer, pancreatic cancer, lung cancer, ovarian cancer, colon cancer, hepatic cancer, head-neck cancer, and cancer of the gallbladder.

Antibody drug conjugates (ADC's) comprising a drug conjugated to antibody or antigen binding fragments thereof that bind to Globo series antigen disclosed herein, as well as methods of use thereof. Methods of use include, without limitation, cancer therapies and diagnostics. The antibodies of the disclosure can bind to certain cancer cell surfaces. Exemplary targets of the antibodies disclosed herein can include carcinomas, such as sarcoma, skin cancer, leukemia, lymphoma, brain cancer, glioblastoma, lung cancer, breast cancer, oral cancer, head-and-neck cancer, nasopharyngeal cancer, esophagus cancer, stomach cancer, liver cancer, bile duct cancer, gallbladder cancer, bladder cancer, pancreatic cancer, intestinal cancer, colorectal cancer, kidney cancer, cervix cancer, endometrial cancer, ovarian cancer, testical cancer, buccal cancer, oropharyngeal cancer, laryngeal cancer and prostate cancer.

Disclosed is a tumor-specific antibody and fluorophore conjugate for detecting, localizing and imaging of various tumors. Also disclosed are methods for detecting, localizing and imaging a solid tumor before or during a tumor resection surgery using the antibody-fluorophore conjugate.

Proteomic methods for identifying cancer related proteins and related products and kits are provided. The cancer specific proteins are extracellular matrix proteins that are associated with various aspects of cancer. Panels or signature sets of proteins useful in the detection, diagnosis and treatment of cancers as well as monitoring therapeutic progress in a cancer patient are provided herein along with methods for their detection and for their use in targeting imaging and/or therapeutic agents to the tumors via binding to the specified proteins. The proteins were identified using proteomics analyzes of tissue samples taken from cancer patients. In certain aspects the proteins are particularly useful in colon cancer patients.
