FDA授予吉利德丙肝复方片LDV/SOF优先审查资格

2014年4月7日讯 /生物谷BIOON/ --吉利德(Gilead)4月7日宣布,FDA已授予ledipasvir(LDV)/sofosbuvir(SOF)固定剂量复方片(LDV/SOF,90mg/400mg)新药申请(NDA)优先审查资格,该药开发用于基因型1慢性丙型肝炎成人感染者的治疗。据估计,在美国约75%的丙肝患者为基因型1 HCV毒株感染。

此前,FDA已授予LDV/SOF固定剂量复方片突破性疗法认定。LDV/SOF NDA的提交,是基于3项III期研究(ION-1、ION-2、ION-3)的数据。

目前,欧洲药品管理局(EMA)正在审查LDV/SOF的上市许可申请(MAA)。

关于Sovaldi(sofosbuvir):

Sovaldi(400mg片剂)为每日一次的口服核苷类似物聚合酶抑制剂,分别于2013年12月和2014年1月获FDA和欧盟批准,作为抗病毒治疗方案的一部分,用于慢性丙型肝炎(HCV)的治疗。

Sovaldi是首个获批可用于C型肝炎全口服治疗方案的药物,在用于特定基因型慢性丙型肝炎治疗时,可消除对传统注射药物干扰素(IFN)的需求。

具体而言,FDA已批准sofosbuvir联合利巴韦林(ribavirin)用于基因型2和基因型3慢性丙型肝炎(hepatitis C)成人患者的治疗。同时,FDA还批准sofosbuvir联合聚乙二醇干扰素(PEG-IFN)和利巴韦林,用于基因型1和基因型4慢性丙型肝炎初治(treat-naive)成人患者的治疗。(生物谷Bioon.com)

英文原文:Gilead Announces U.S. FDA Priority Review Designation for Ledipasvir/Sofosbuvir Fixed-Dose Combination Tablet for Chronic Hepatitis C Genotype 1 Infection

-- Final FDA Decision Anticipated by October 10, 2014 --

FOSTER CITY, Calif.--(BUSINESS WIRE)--Apr. 7, 2014-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the U.S. Food and Drug Administration (FDA) has granted priority review to the company’s New Drug Application (NDA) for a once-daily fixed-dose combination of the NS5A inhibitor ledipasvir (LDV) 90 mg and the nucleotide analog polymerase inhibitor sofosbuvir (SOF) 400 mg for the treatment of chronic hepatitis C genotype 1 infection in adults. Gilead filed the NDA for LDV/SOF on February 10, 2014, and the FDA has set a target action date under the Prescription Drug User Fee Act (PDUFA) of October 10, 2014.

The FDA has also assigned LDV/SOF a Breakthrough Therapy designation. The FDA grants Breakthrough Therapy designation and priority review status to investigational medicines that may offer major advances in treatment over existing options. The data submitted in the NDA are from three Phase 3 studies, ION-1, ION-2 and ION-3, and support the use of LDV/SOF in adults with genotype 1 HCV infection, with a treatment duration of eight or 12 weeks depending on prior treatment history and whether they have cirrhosis. Approximately 75 percent of people infected with HCV in the United States have the genotype 1 strain of the virus.

A marketing application for LDV/SOF is also under review in the European Union, and was validated by the European Medicines Agency (EMA) on March 27, 2014. The agency has accepted Gilead’s request for accelerated assessment of LDV/SOF, a designation that is granted to new medicines of major public health interest. If accepted, accelerated assessment could shorten the EMA’s review time of LDV/SOF by two months, although it does not guarantee a positive opinion from the Committee for Medicinal Products for Human Use or approval by the European Commission.

LDV/SOF is an investigational product and its safety and efficacy have not yet been established.

SOF as a single agent was approved by the FDA under the tradename Sovaldi® on December 6, 2013 and by the European Commission on January 17, 2014.
