吉利德(Gilead)11月18日宣布,整合酶抑制剂Vitekta(elvitegravir,85mg和100mg)已获欧盟委员会(EC)批准,用于无任何已知elvitegravir抗性相关突变的HIV-1成人感染者的治疗。
Vitekta旨在用作HIV治疗方案的一部分,该方案包含一种ritonavir增效蛋白酶抑制剂。Vitekta通过阻断病毒整合至人体细胞基因组,干扰HIV病毒的复制。在临床试验中,Vitekta在感染HIV抗药株的患者群体中,能够有效抑制HIV病毒。
Vitekta已获批的2种剂量为85mg和150mg,85mg剂量Vitekta旨在与ritonavir增效(ritonavir-boosted)的蛋白酶抑制剂atazanavir(300mg)和lopinavir(400mg)联合用药;150mg剂量Vitekta旨在与ritonavir增效的蛋白酶抑制剂darunavir(600mg)和fosamprenavir(700mg)联合用药。
Vitekta的获批,是基于为期96周的III期研究(Study 145)的数据,该项研究中,Vitekta(每日1次)达到了相较于整合酶抑制剂raltegravir(每日2次)的非劣性终点。
Vitekta也是吉利德4合1型抗HIV新药Stribild(elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir disoproxil (as fumarate) 245 mg)的一部分,该药分别于2012年6月和2013年5月获欧盟批准,用于HIV初治患者或未携带任何与3种抗逆转录病毒药物抗性相关已知突变的HIV成人感染者的治疗。
英文原文:European Commission Approves Gilead’s Vitekta™, an Integrase Inhibitor for the Treatment of HIV-1 Infection
FOSTER CITY, Calif.--(BUSINESS WIRE)--Nov. 18, 2013-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the European Commission has granted marketing authorization for Vitekta™ (elvitegravir 85 mg and 150 mg) tablets, an integrase inhibitor for the treatment of HIV-1 infection in adults without known mutations associated with resistance to elvitegravir. Vitekta is indicated for use as part of HIV treatment regimens that include a ritonavir-boosted protease inhibitor. Vitekta interferes with HIV replication by blocking the virus from integrating into the genetic material of human cells. In clinical trials, Vitekta was effective in suppressing HIV among patients with drug-resistant strains of HIV.
“Vitekta offers people with HIV who have failed prior therapy or who have developed drug resistance an important new treatment option,” said Norbert Bischofberger, PhD, Executive Vice President, Research and Development and Chief Scientific Officer, Gilead Sciences. “Vitekta is only the second integrase inhibitor to become available in the European Union. Today’s approval exemplifies Gilead’s ongoing commitment to meeting the evolving needs of people living with HIV.”
Vitekta has been approved in two doses: an 85 mg tablet is indicated for use with the ritonavir-boosted protease inhibitors atazanavir 300 mg and lopinavir 400 mg; and a 150 mg tablet is indicated for use with the ritonavir-boosted protease inhibitors darunavir 600 mg and fosamprenavir 700 mg. The approval is supported by 96-week data from a Phase 3 study (Study 145) in which Vitekta dosed once daily was found to be non-inferior to the integrase inhibitor raltegravir dosed twice daily, each administered with a background regimen that included a fully active ritonavir-boosted protease inhibitor and a second antiretroviral agent. Patients enrolled in the trial were required to have genotypic HIV drug resistance or at least six months of treatment experience with two or more different classes of antiretrovirals.
Vitekta was well tolerated in clinical studies and most adverse reactions were mild to moderate. The most common adverse reactions (all grades) observed were diarrhea (7.1 percent) and nausea (4 percent); please see additional Important Safety Information below.
Vitekta is also a component of Gilead’s Stribild® (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg), a once-daily single tablet regimen for HIV that was approved in the United States in August 2012 for treatment-naïve adults and by the European Commission in May 2013 for adults who are treatment-naïve or who have no known mutations associated with resistance to any of the three antiretroviral agents in Stribild. Gilead submitted a new drug application to the U.S. Food and Drug Administration (FDA) for Vitekta as a single agent in June 2012 and received a Complete Response Letter in April 2013. Gilead is working on resubmitting the application to the FDA.
