GSK plc (LSE/NYSE: GSK) today announced that the European Medicines Agency has accepted for review the marketing authorisation application (MAA) for the use of linerixibat, an investigational targeted inhibitor of the ileal bile acid transporter (IBAT), for the treatment of cholestatic pruritus in patients with PBC, a rare autoimmune liver disease. .

GSK plc（LSE/NYSE：GSK）今天宣布，欧洲药品管理局已受理 linerixibat 的上市许可申请（MAA），这是一种研究性的回肠胆汁酸转运蛋白（IBAT）靶向抑制剂，用于治疗原发性胆汁性胆管炎（PBC）患者胆汁淤积性瘙痒症，PBC是一种罕见的自身免疫性肝病。

Kaivan Khavandi, SVP, Global Head, Respiratory, Immunology & Inflammation R&D, GSK, said:

凯万·哈万迪，高级副总裁，全球呼吸、免疫与炎症研发主管，GSK，表示：

“The EMA acceptance of this file marks another significant step forward in the progress of linerixibat, following FDA acceptance earlier this month. We believe linerixibat has the potential to bring relief to patients living with relentless itch associated with PBC, a condition that often disrupts sleep, and for which there are currently few effective treatment options available.”.

“EMA对该文件的接受标志着linerixibat在进展中又迈出了重要的一步，此前FDA已于本月初接受了该文件。我们相信linerixibat有潜力为那些因PBC而遭受持续瘙痒的患者带来缓解，这种症状常常扰乱睡眠，且目前有效的治疗选择很少。”

The application is based on positive data from the GLISTEN phase III trial, presented in May at the European Association for the Study of the Liver (EASL) Congress. GLISTEN met both primary and key secondary endpoints demonstrating a rapid, significant and sustained improvement in cholestatic pruritus and itch-related sleep interference versus placebo.

该申请基于 GLISTEN III 期试验的积极数据，该数据于 5 月在欧洲肝病研究协会 (EASL) 大会上公布。GLISTEN 达到了主要和关键次要终点，证明与安慰剂相比，胆汁淤积性瘙痒和与瘙痒相关的睡眠干扰得到了迅速、显著且持续的改善。

The safety profile of linerixibat was consistent with previous studies and the mechanism of IBAT inhibition..

Linerixibat 的安全性特征与之前的研究和 IBAT 抑制机制一致。

Linerixibat is currently not approved anywhere in the world.

Linerixibat 目前在全球任何地方都未获批准。

About cholestatic pruritus in PBC

关于PBC中的胆汁淤积性瘙痒

In PBC, a cholestatic liver disease, bile flow from the liver is disrupted. The resulting excess bile acids in circulation are thought to play a causal role in cholestatic pruritus, an internal itch that cannot be relieved by scratching. Pruritus can occur at any stage of PBC disease or biochemical control, and is experienced in varying degrees of severity by up to 90% of people living with PBC..

在原发性胆汁性胆管炎（PBC）中，这是一种胆汁淤积性肝病，肝脏的胆汁流动受到阻碍。循环系统中过量的胆汁酸被认为在胆汁淤积性瘙痒中起因果作用，这种内部瘙痒无法通过抓挠缓解。瘙痒可能在PBC病程或生化控制的任何阶段发生，并且多达90%的PBC患者会经历不同程度的严重瘙痒。

The first line treatment for PBC controls disease in approximately 70% of patients, but does not reduce the severity or impact of the pruritus.

原发性胆汁性胆管炎的一线治疗可控制大约70%患者的病情，但不能减轻瘙痒的严重程度或影响。

Cholestatic pruritus is a serious condition that can be debilitating, with patients experiencing sleep disturbance, fatigue, impaired quality of life and even sometimes requiring liver transplantation in the absence of liver failure.

胆汁淤积性瘙痒是一种严重的疾病，可能会导致患者虚弱，出现睡眠障碍、疲劳、生活质量下降，甚至有时在没有肝衰竭的情况下需要进行肝移植。

About linerixibat (GSK2330672)

关于linerixibat（GSK2330672）

Linerixibat is an IBAT inhibitor, a targeted oral agent with potential to treat cholestatic pruritus (itch) associated with the rare autoimmune liver disease known as PBC. By inhibiting bile acid re-uptake, linerixibat reduces multiple mediators of pruritus in circulation. The US Food and Drug Administration and the European Medicines Agency have granted orphan drug designation for linerixibat in the treatment of cholestatic pruritus in patients with PBC.

Linerixibat是一种IBAT抑制剂，是一种有针对性的口服药物，有可能治疗与罕见的自身免疫性肝病（称为PBC）相关的胆汁淤积性瘙痒。通过抑制胆汁酸再摄取，linerixibat减少循环中多种瘙痒介质。美国食品药品监督管理局和欧洲药品管理局已授予linerixibat在治疗PBC患者胆汁淤积性瘙痒方面的孤儿药资格。

Linerixibat is currently under regulatory review in the US and UK. .

Linerixibat目前在美国和英国处于监管审查中。

About the GLISTEN trial

关于GLISTEN试验

GLISTEN is a double-blind, randomised, placebo-controlled, phase III trial (NCT04950127; GSK study 212620) conducted in 238 PBC patients with cholestatic pruritus initially enrolled equally into active and placebo arms (n=119 each). The primary analysis evaluated the efficacy and safety of linerixibat compared with placebo.

GLISTEN 是一项双盲、随机、安慰剂对照的 III 期临床试验（NCT04950127；GSK 研究 212620），在 238 名胆汁淤积性瘙痒的原发性胆管炎（PBC）患者中进行，最初平均分配至活性药物组和安慰剂组（每组各 119 人）。主要分析评估了 linerixibat 与安慰剂相比的疗效和安全性。

The primary and key secondary endpoints of the study were met, demonstrating a rapid, significant and sustained improvement in cholestatic pruritus and itch-related sleep interference versus placebo. .

研究的主要和关键次要终点均达到，显示出与安慰剂相比，胆汁淤积性瘙痒和与瘙痒相关的睡眠干扰得到了快速、显著且持续的改善。

Participants with moderate to severe itch were enrolled. Participants initially received either linerixibat or placebo and had the potential to cross over in a part B of the trial. Primary and secondary outcome measures were assessed using a 0-10 numerical rating scale for worst itch and itch-related sleep interference.

招募了有中度至重度瘙痒的参与者。参与者最初接受 linerixibat 或安慰剂治疗，并有可能在试验的 B 部分交叉。主要和次要结局指标通过 0-10 数字评分量表评估最严重瘙痒和与瘙痒相关的睡眠干扰。

Stable use of guideline suggested anti-itch therapy was permitted. The trial was the first truly global PBC study completed in 19 countries including the Americas, Europe, China and Japan..

允许稳定使用指南建议的止痒疗法。该试验是第一个真正全球性的PBC研究，在包括美洲、欧洲、中国和日本等19个国家完成。
