安斯泰来（Astellas）美国子公司今天宣布，ASTAGRAF XL（他克莫司缓释胶囊，tacrolimus extended release capsules）获FDA批准，与霉酚酸酯（MMF）及皮质类醇联用、结合或无巴利昔单抗（basiliximab）诱导，用于预防成人肾移植受者中的器官排斥。安斯泰来于2012年9月提交了该药的新药申请（NDA）。

在2007年，他克莫司缓释胶囊在欧洲获批以商品名Advagraf销售；2008年，该药在日本获批以商品名Graceptor销售。总体而言，他克莫司缓释胶囊已获得了全球73个国家的监管批准，每年经该药治疗的患者数超过14万人。

Astellas Announces FDA Approval of ASTAGRAF XL(TM) (tacrolimus extended-release capsules) for the Prophylaxis of Organ Rejection in Adult Kidney Transplant Recipients
NORTHBROOK, Ill., July 19, 2013 /PRNewswire/ -- Astellas Pharma US, Inc. ("Astellas"), a U.S. subsidiary of Tokyo-based Astellas Pharma Inc. (Tokyo: 4503), announced today that the U.S. Food and Drug Administration (FDA) has approved ASTAGRAF XL(TM) (tacrolimus extended-release capsules) for the prophylaxis of organ rejection in patients receiving a kidney transplant with mycophenolate mofetil (MMF) and corticosteroids, with or without basiliximab induction.
"Each transplant recipient is different and requires a personalized treatment approach. The approval of ASTAGRAF XL marks an important milestone in post-transplant care as it provides physicians with a new treatment option for kidney transplant recipients," said Sef Kurstjens, M.D., PhD., chief medical officer, Astellas Pharma, Inc. "Astellas is pleased to continue our more than 20-year commitment to the field of transplant immunology."
ASTAGRAF XL is the first once-daily oral tacrolimus formulation available in the U.S. for kidney transplant recipients. ASTAGRAF XL offers a potentially promising treatment option for appropriate kidney transplant recipients as a core component of an immunosuppressive regimen for the prophylaxis of organ rejection.
The two primary, randomized, comparative phase 3 clinical studies to support FDA approval enrolled 1,093 patients (545 on tacrolimus extended-release) in the U.S., Europe, Canada, South America, Australia and South Africa. Astellas was granted marketing approval for tacrolimus extended-release capsules under the trade name Advagraf(R) in Europe in 2007 and under the trade name Graceptor(R) in Japan in 2008. In total, tacrolimus extended-release capsules have been approved for use in 73 countries.
