Sanofi provides update on tolebrutinib in primary progressive multiple sclerosis 赛诺菲提供有关托勒布替尼在原发性进行性多发性硬化症中的最新信息PERSEUS phase 3 study in primary progressive multiple sclerosis did not meet its primary endpoint in delaying time to onset of 6-month composite confirmed disability progression compared to placebo PERSEUS 第三阶段研究在原发性进行性多发性硬化症中未达到其主要终点,即与安慰剂相比,未能延迟6个月复合确认残疾进展的起始时间。The safety profile of tolebrutinib was consistent with previous studies 托勒布替尼的安全性特征与之前的研究一致。Paris, December 15, 2025 巴黎,2025年12月15日. Results from the PERSEUS phase 3 study (clinical study identifier: . PERSEUS 3期研究的结果(临床研究标识符:NCT04458051 NCT04458051) showed that tolebrutinib did not meet its primary endpoint in delaying time to 6-month composite confirmed disability progression (cCDP) in participants with primary progressive multiple sclerosis (PPMS), which represents 10% of the overall multiple sclerosis patient population. Based on these results, Sanofi will not pursue regulatory registration for PPMS.. )显示,在原发性进展型多发性硬化症(PPMS)患者中,tolebrutinib未能达到其延缓6个月复合确认残疾进展(cCDP)时间的主要终点,这类患者占整个多发性硬化症患者群体的10%。基于这些结果,赛诺菲将不会寻求PPMS的监管注册。'We are disappointed by today’s results; however, we do believe that these results will improve our understanding of the underlying disease biology of multiple sclerosis,” “我们对今天的结果感到失望;然而,我们确实相信这些结果将提高我们对多发性硬化症潜在疾病生物学的理解。”said 说Houman Ashrafian 侯曼·阿什拉菲安, Executive Vice President, Head of Research & Development at Sanofi. 执行副总裁,赛诺菲研发部门负责人。“We extend our deepest appreciation to the study participants, their families, and healthcare professionals who support our scientific and innovative vision. Our commitment to the multiple sclerosis community remains unchanged, as do our efforts to pursue novel advancements that address existing unmet needs and we remain confident in the value tolebrutinib can bring to those living with non-relapsing secondary progressive multiple sclerosis.”. “我们向参与研究的人员、他们的家人以及支持我们科学和创新愿景的医疗专业人员表示最深切的感谢。我们对多发性硬化症群体的承诺依然不变,我们致力于追求能够满足现有未满足需求的新进展,同时我们依然相信 tolebrutinib 能够为非复发性继发进展型多发性硬化症患者带来的价值。”Preliminary analysis showed the safety profile was consistent with previous tolebrutinib studies. As previously reported, drug-induced liver injury (DILI) is an identified risk of tolebrutinib. Strict adherence to liver monitoring requirements, and prompt management of liver enzyme elevations, are important to mitigate DILI risk. 初步分析显示,其安全性与之前的tolebrutinib研究一致。正如之前报道的,药物性肝损伤(DILI)是tolebrutinib的一个已知风险。严格遵守肝脏监测要求,并及时处理肝酶升高,对于减轻DILI风险非常重要。Full safety and efficacy results will be presented at a forthcoming medical meeting.. 完整安全性和有效性结果将在即将召开的医学会议上公布。Tolebrutinib was provisionally approved in the United Arab Emirates in July 2025 for the treatment of non-relapsing secondary progressive multiple sclerosis and to slow disability accumulation independent of relapse activity in adults. It is currently under regulatory review in the EU and other jurisdictions worldwide. 托莱布替尼于2025年7月在阿拉伯联合酋长国获得临时批准,用于治疗非复发性继发进展型多发性硬化症,并减缓成人与复发活动无关的残疾积累。目前,该药物正在欧盟及其他全球司法管辖区接受监管审查。Tolebrutinib was previously granted . 托勒布替尼此前已获批准。breakthrough therapy 突破性疗法designation by the FDA in December 2024. FDA于2024年12月指定。Financial considerations 财务方面的考虑Sanofi will conduct an impairment test in accordance with IFRS (IAS 36) on the intangible asset value attached to tolebrutinib with a status to be provided with Q4 and FY 2025 results in January 2026. The outcome of this test will have no impact to the business net income / business EPS and there is no change to the financial guidance for 2025.. 赛诺菲将根据国际财务报告准则(IFRS,IAS 36)对与tolebrutinib相关的无形资产价值进行减值测试,并将于2026年1月随2025年第四季度及全年财报结果提供相关情况。该测试结果对业务净利润/业务每股收益无影响,且2025年的财务指引保持不变。About multiple sclerosis 关于多发性硬化症MS is a progressive neurologic disorder characterized by accumulation of disability with shifts 多发性硬化症是一种进行性神经系统疾病,其特征是随着病情发展而积累的残疾。in the underlying biology and dominant drivers of disability over time impacting clinical 在潜在的生物学和随时间推移影响临床的残疾主要驱动因素方面presentation and treatment response. 表现和治疗反应。The clinical presentation of PPMS is characterized by a slow, insidious neurologic decline, often with a predominance of spinal cord involvement, and symptoms gradually worsen over time without periods of improvement. 原发进展型多发性硬化症 (PPMS) 的临床表现特征为缓慢、隐匿的神经系统衰退,常以脊髓受累为主,症状随着时间逐渐恶化,且无缓解期。Secondary progressive multiple sclerosis typically refers to people with a previous diagnosis of relapsing MS who have stopped experiencing relapses but continue to experience disability accumulation, in the absence of relapses. 继发进展型多发性硬化通常指既往诊断为复发缓解型多发性硬化的患者,他们在没有复发的情况下停止了复发,但仍然持续出现残疾累积。Addressing disability accumulation remains a significant unmet need in MS, as treatment options are limited. 多发性硬化症治疗中,解决残疾累积问题仍然是一个重要的未满足需求,因为治疗选择有限。About PERSEUS 关于PERSEUSPERSEUS (clinical study identifier: 珀尔修斯(临床研究标识符: NCT04458051 NCT04458051) is a global, double-blind, randomized phase 3 clinical study which evaluated the efficacy and safety of tolebrutinib compared to placebo in participants with PPMS. Participants were randomized (2:1) to receive either an oral daily dose of tolebrutinib or matching placebo for up to approximately 60 months. )是一项全球性、双盲、随机的三期临床研究,评估了托勒布替尼与安慰剂在PPMS患者中的疗效和安全性。参与者以2:1的比例随机分配,接受每日口服托勒布替尼或匹配的安慰剂,持续约60个月。The inclusion criteria for the study included participants aged 18–55 years old, a diagnosis of PPMS as per the 2017 revised McDonald criteria, an EDSS score ≥2.0 and ≤6.5 at screening, positive cerebrospinal fluid findings (OCBs and/or elevated IgG index) and either no access, intolerance, or perceived lack of efficacy to ocrelizumab.. 研究的纳入标准包括年龄在18至55岁之间的参与者,根据2017年修订的麦克唐纳标准诊断为PPMS,筛查时EDSS评分≥2.0且≤6.5,脑脊液检查结果呈阳性(OCBs和/或IgG指数升高),以及无法获得、不耐受或认为奥克瑞珠单抗疗效不足的患者。The primary endpoint was six-month composite confirmed disability progression (cCDP), defined as increase over at least six months of ≥1.0 point from the baseline expanded disability status scale (EDSS) score when the baseline score is ≤5.5, or ≥0.5 points when the baseline EDSS score is >5.5, or ≥20% from the baseline T25-FW, or ≥20% from the baseline 9-HPT. 主要终点是六个月的复合确认残疾进展(cCDP),定义为基线扩展残疾状态量表(EDSS)评分≤5.5时,至少六个月增加≥1.0分,或基线EDSS评分>5.5时增加≥0.5分,或基线T25-FW增加≥20%,或基线9-HPT增加≥20%。Secondary endpoints included six-month confirmed disability progression, three-month cCDP, number of new/enlarging T2 lesions as detected by MRI, time to confirmed disability improvement, change in brain volume loss, change in cognitive function, quality of life, pharmacokinetics, as well as the safety and tolerability of tolebrutinib. 次要终点包括六个月确认的残疾进展、三个月确认的持续临床疾病进展(cCDP)、通过核磁共振成像检测到的新发/扩大的T2病变数量、确认的残疾改善时间、脑容量损失变化、认知功能变化、生活质量、药代动力学,以及托勒布替尼的安全性和耐受性。. 。About tolebrutinib 关于托勒布替尼Tolebrutinib is an investigational, oral, brain-penetrant Bruton’s tyrosine kinase inhibitor specifically designed to target smoldering neuroinflammation, a key driver of disability progression in MS.
