Summary for Patent: 9,192,663
Title: | Antibodies for epidermal growth factor receptor 3 (HER3) |
Abstract: | This invention relates to antibodies or fragments thereof which interact with HER family of receptors, e.g., HER3 receptor. In particular, it relates to antibodies or fragments thereof that recognize a conformational epitope of HER3 receptor comprising residues from both domains 2 and 4 resulting in inhibition of both ligand-dependent and ligand-independent signal transduction; and allow ligand binding (e.g., neuregulin), while preventing ligand-induced activation of signal transduction. These antibodies or fragments can be used to treat a number of diseases or disorders characterized by increased levels of HER3 expression (e.g., esophageal cancer). These antibodies or fragments can be used to treat a number of diseases or disorders characterized by the antibodys or fragments ability to decrease tissue weight (e.g., prostate or uterine weights) or to induce atrophy of tissue (e.g., atrophy of male breast). |

Application Number: | 13/693,330 |
Patent Claims: | 1. A method of treating benign prostate hyperplasia comprising: selecting a patient suffering from benign prostate hyperplasia; and administering an antibody or fragment thereof that
specifically binds to a HER3 receptor, such that the antibody or fragment thereof binds to a conformational epitope comprising amino acid residues within domain 2 and domain 4 of the HER3 receptor and blocks both ligand-dependent and ligand-independent
signal transduction, wherein the antibody or fragment thereof comprises: (a) a heavy chain variable region CDR1 of SEQ ID NO: 38; a heavy chain variable region CDR2 of SEQ ID NO: 39; a heavy chain variable region CDR3 of SEQ ID NO: 40; a light chain
variable region CDRI of SEQ ID NO: 41; a light chain variable region CDR2 of SEQ ID NO: 42; and a light chain variable region CDR3 of SEQ ID NO: 43; (b) a heavy chain variable region CDR1 of SEQ ID NO: 44; a heavy chain variable region CDR2 of SEQ ID
NO: 45; a heavy chain variable region CDR3 of SEQ ID NO: 46; a light chain variable region CDR1 of SEQ ID NO: 47; a light chain variable region CDR2 of SEQ ID NO: 48; and a light chain variable region CDR3 of SEQ ID NO: 49; (c) a variable heavy
chain (VH) sequence of SEQ ID NO: 51 and a variable light chain (VL) sequence of SEQ ID NO: 50; (d) a variable heavy chain (VH) sequence having SEQ ID NO: 141 and a variable light chain (VL) sequence having of SEQ ID NO: 140; (e) a variable heavy chain
(VH) sequence selected from the group consisting of SEQ ID NOs.: 402-423; (f) a variable light kappa chain (VK) sequence selected from the group consisting of SEQ ID NOs.: 443-461 and SEQ ID NOs.: 479-480; or (g) a sequence selected from the group
consisting of SEQ ID NOs.: 487-492; thereby treating benign prostate hyperplasia.
2. The method of claim 1, wherein the antibody or fragment thereof is administered by a route selected from the group consisting of oral, subcutaneous, intraperitoneal, intramuscular, intracerebroventricular, intraparenchymal, intrathecal, intracranial, buccal, mucosal, nasal, and rectal administration. 3. The method of claim 1, wherein the antibody or fragment is formulated into a pharmaceutical composition comprising a physiologically acceptable carrier, excipient, or diluent. 4. The method of claim 3, further comprising an additional therapeutic agent. 5. The method of claim 4, wherein the additional therapeutic agent is selected from the group consisting of an HER1 inhibitor, a HER2 inhibitor, a HER3 inhibitor, a HER4 inhibitor, an mTOR inhibitor and a PI3 Kinase inhibitor. 6. The method of claim 5, wherein the additional therapeutic agent is a HER1 inhibitor selected from the group consisting of Matuzumab (EMD72000), Cetuximab, Panitumumab, mAb 806, Nimotuzumab, Gefitinib, CI-1033 (PD183805), Lapatinib (GW-572016), Lapatinib Ditosylate, Erlotinib HCL (OSI-774), PKI-166, and N-[4-[(3-Chloro-4-fluorophenyl)amino]-7-[[(3''S'')-tetrahydro-3-furanyl]o- xy]-6-quinazolinyl]-4(dimethylamino)-2-butenamidea HER2 inhibitor selected from the group consisting of Pertuzumab, Trastuzumab, MM-111, neratinib, lapatinib or lapatinib ditosylate/Tykerb.RTM.; a HER3 inhibitor selected from the group consisting of, MM-121, MM-111, IB4C3, 2DID12 (U3 Pharma AG), AMG888 (Amgen), AV-203(Aveo), MEHD7945A (Genentech), MOR10703 (Novartis) and small molecules that inhibit HER3; and a HER4 inhibitor. 7. The method of claim 5, wherein the additional therapeutic agent is an mTOR inhibitor selected from the group consisting of Temsirolimus, ridaforolimus/Deforolimus, AP23573, MK8669, and everolimus. 8. The method of claim 5, wherein the additional therapeutic agent is a PI3 Kinase inhibitor selected from the group consisting of GDC 0941, BEZ235, BMK120 and BYL719. |
