The present invention relates to an isolated specific binding member capable of binding sialyl-di-Lewis.sup.a, and associated treatments and pharmaceutical compositions for treatment of cancer.

The present invention relates to methods of cancer therapy using subcutaneous administration of antibody-drug conjugates (ADCs). Preferably, the ADC comprises an antibody that binds to Trop-2, CEACAM5, CEACAM6, CD20, CD22, CD30, CD46, CD74, Her-2, folate receptor, or HLA-DR. More preferably, the drug is SN-38. Subcutaneous administration is at least as effective as intravenous administration of the same ADC. Surprisingly, subcutaneous administration can be used without inducing unmanageable adverse local toxicity at the injection site. Subcutaneous administration is advantageous in requiring less frequent administration, substantially reducing the amount of time required for intravenous administration, and reducing the levels of systemic toxicities observed with intravenous administration. When administered at specified dosages and schedules, the ADCs can reduce solid tumors in size, reduce or eliminate metastases and are effective to treat cancers resistant to standard therapies, such as radiation therapy, chemotherapy or immunotherapy.

The invention provides protein-active agent conjugates having an amino acid motif that can be recognized by an isoprenoid transferase. The invention also provides compositions containing the conjugates. The invention further provides methods for using the conjugates to deliver the active agent to a target cell, as well as methods for using the conjugates to treat a subject in need thereof (e.g., a subject in need of the active agent)

The present invention relates to therapeutic conjugates with improved ability to target various diseased cells containing a targeting moiety (such as an antibody or antibody fragment), a linker and a therapeutic moiety, and further relates to processes for making and using the conjugates.

The present invention relates to an antibody specifically binding to glypican 3 (GPC3), a nucleic acid encoding the antibody, a vector and a host cell containing the nucleic acid, a method of preparing the antibody, and a pharmaceutical composition for treating cancer or tumor, containing the antibody as an active ingredient. The antibody specifically binding to glypican 3 according to the present invention may be effectively used to treat cancer or tumor, particularly, hepatocellular carcinoma due to high affinity and specificity to glypican 3.

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.

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.

The present invention relates to therapeutic immunoconjugates comprising SN-38 attached to an antibody or antigen-binding antibody fragment. The antibody may bind to Trop-2 or CEACAM5 and the immunoconjugate may be administered at a dosage of between 4 mg/kg and 16 mg/kg, preferably 4, 6, 8, 9, 10, 12, or 16 mg/kg. When administered at specified dosages and schedules, the immunoconjugate can reduce solid tumors in size, reduce or eliminate metastases and is effective to treat cancers resistant to standard therapies, such as radiation therapy, chemotherapy or immunotherapy. Surprisingly, the immunoconjugate is effective to treat cancers that are refractory to or relapsed from irinotecan.

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 involving treatment, amelioration, and/or diagnosis of a T-cell lymphoma.

Compounds and compositions are disclosed in which a NAMPT Drug Unit is conjugated to a targeting Ligand Unit through quaternization by a Linker Unit from which a NAMPT inhibitor compound or derivative thereof is released at the targeted site of action. Methods for treating diseases characterized by the targeted abnormal cells, such as those of cancer or an autoimmune disease, using the compounds and compositions of the invention are also disclosed.
