Axitinib (AG013736; trade name Inlyta) is a small molecule tyrosine kinase inhibitor developed by Pfizer. It has been shown to significantly inhibit growth of breast cancer in animal (xenograft) models and has shown partial responses in clinical trials with ] (RCC) and several other tumour types. It was approved by the U.S. Food and Drug Administration after showing a modest increase in progression-free survival,〔(【引用サイトリンク】title=FDA Approves Inlyta for Advanced Renal Cell Carcinoma )〕 though there have been reports of fatal adverse effects. ==Medical uses== A Phase II clinical trial showed good response in combination chemotherapy with gemcitabine for advanced pancreatic cancer. However, Pfizer reported on January 30, 2009 that Phase III clinical trials of the drug when used in combination with gemcitabine showed no evidence of improved survival rates over treatments using gemcitabine alone for advanced pancreatic cancer and halted the trial.〔(【引用サイトリンク】 Pfizer pancreatic cancer drug fails, trial halted )〕 In 2010, a Phase III trial for previously treated metastatic renal cell carcinoma (mRCC) showed significantly extended progression-free survival when compared to sorafenib. In December 2011, the Oncologic Drugs Advisory Committee (ODAC) voted unanimously to recommend the approval of axitinib for the second-line treatment of patients with advanced renal cell carcinoma (RCC), based on the results of the Phase III trial comparing axitinib and sorafenib. It has received FDA (27 January 2012), EMA (13 September 2012), MHRA (3 September 2012) and TGA (26 July 2012) approval for use as a treatment for renal cell carcinoma. A study published in 2015 showed that axitinib effectively inhibits a mutated gene (BCR-ABL1()) that is common in chronic myeloid leukemias and adult acute lymphoblastic leukemias which have become resistant to other tyrosine kinase inhibitors like imatinib. This is one of the first examples of a new indication for an existing drug being discovered by screening known drugs using a patient's own cells. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「axitinib」の詳細全文を読む スポンサード リンク
