New Drug Approvals 2013 - Pt. XIX - Ibrutinib (ImbruvicaTM)

ATC Code: Wikipedia: Ibrutinib On November 13, 2013, the FDA approved Ibrutinib (Imbruvica TM ) for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. MCL is a subtype of B-cell lymphoma and accounts for 6% of non-Hodgkin's lymphoma cases. In an open-label, multi-center, single-arm trial of 111 previously treated patients, Ibrutinib showed a 65.8% response rate. Ibrutinib is an irreversible inhibitor of the Tyrosine-protein kinase BTK (Uniprot:Q06187; ChEMBL: CHEMBL5251 ; canSAR target synopsis ) and is the first approved targeted BTK inhibitor. It forms a covalent bond with a cysteine residue via a Michael acceptor mechanism, in the BTK active site, leading to inhibition of BTK enzymatic activity Ibrutinib (ChEMBL: CHEMBL1873475 ; canSAR drug synopsis ; also known as CRA-032765 and PCI-32765) has the formula C25H24N6O2 and a molecular weight 440.50. It is absorbed after oral administration with a median Tma...

New Drug Approvals 2013 - Pt. XVIII - Obinutuzumab (GazyvaTM)

ATC Code:  L01XC15 Wikipedia: Obinutuzumab On November 1, 2013 the FDA approved obinutuzumab (Gazyva TM ) for use in combination with chlorambucil  (a nitrogen mustard alkylating agent) for the treatment of patients with previously untreated chronic lymphocytic leukemia (CLL). CLL is the most common type of Leukaemia accounting for 35% of all reported Leukaemias (See CRUK CLL page). In a randomized three-arm clinical study, the combination of obinutuzumab (in combination with chlorambucil) improved the progression-free survival (PFS) of patients to 23.0 months compared to 11.1 months for chlorambucil alone. Obinutuzumab ( CHEMBL1743048 ) is a humanized anti-CD20 monoclonal antibody of ca . 150 kDa molecular weight. Its target, the B-lymphicyte antigen CD20, is the product of the gene MS4A1 (Uniprot: P11836; ChEMBL: CHEMBL2058 ; canSAR target synopsis . The CD20 antigen is expressed on the surface of pre B- and mature B-lymphocytes. Obinutuzumab mediates B-ce...

New Drug Approvals 2011 - Pt. X Vandetanib (ZactimaTM)

ATC code: L01XE12 On the 6th April 2011, the FDA approved Vandetanib (trade name: Zactima TM , ATC code: L01XE12, NDA 022405), a multi-kinase inhibitor, for the treatment of symptomatic or progressive medullary thyroid cancer in patients with unresectable locally advanced or metastatic disease. ( medullary thyroid cancer ; CRUK Thyroid cancer ; ICD C73 ) Medullary thyroid cancer is a rare form of Thyroid cancer, but is associated with poorer prognosis. While the primary tumor can be successfully removed using surgery and radiotherapy, and thus can have a high 5 and 10 year survival rate (>90%), the metastatic disease remains challenging and is has a low 40% survival rate. Medullary thyroid cancer can be a sporadic or hereditary disease, and has complex underlying genetic causes. Approximately 25% of cases are associated with the RET (REarranged during Transfection) proto-oncogene. RET mutations cause Multiple Endocrine Neoplasia type 2 (MEN 2) which increases the r...

canSAR v1.0 launched

Yesterday, Cancer Research UK press released the launch of the first full version of canSAR - the Institute of Cancer Research's integrated cancer research and drug discovery resource. canSAR integrates large volumes of disparate data covering most aspects of cancer biology and chemistry, and is an example of how to complement the chEMBL database with therapeutic area specific knowledge. canSAR integrates biological annotation, gene expression, RNA interference studies, structural biology and protein interaction network data - as well as chemical and pharmacological data. It contains annotation on the entire human proteome, and contains >8 million experimental data points including RNAi and chemical screening data. For full release notes please see canSAR news . canSAR is updated monthly. As well as the wonderful chEMBL, the data in canSAR comes from a large number of sources, including ArrayExpress , PDBe , ROCK , STRING , Genomics of Drug Sensitivity in Cancer , COSM...
