AiCuris Reports Positive Phase 1 Clinical Trial Results with Immunomodulator AIC649 in Patients with Chronic Hepatitis B

AiCuris Reports Positive Phase 1 Clinical Trial Results with Immunomodulator AIC649
in Patients with Chronic Hepatitis B

Single intravenous dose phase 1 trial showed that AIC649 was safe and well tolerated in all dose groups
The trial provides evidence that AIC649 stimulates the immune system of chronic hepatitis B patients
Further trials to study the potential of AIC649 to induce a functional cure in chronic hepatitis B virus (HBV)-infection is warranted
Wuppertal, Germany, September 3rd, 2018 - AiCuris Anti-infective Cures GmbH, a leading company in the discovery and development of drugs targeting infectious diseases, announced the results from its first-in-human, single-ascending dose clinical phase 1 trial with AIC649 in patients suffering from chronic hepatitis B (CHB).

The randomized, multi-center, double-blind, placebo-controlled phase 1 clinical trial was designed to assess the safety, tolerability and pharmacodynamics of single ascending intravenous doses of AIC649 in CHB patients. Thirty-two patients were randomized in four ascending dose groups. Patients in each group received either single dosages of AIC649 or placebo and were monitored for 84 days. The majority of the patients were male, HBeAntigen (HBeAg)-negative, and HBV treatment naive.

A single intravenous dose of AIC649 was safe and well tolerated in all dose groups. There was no dose limiting toxicity and the maximum tolerated dose was not reached with the highest dose administered. Despite the heterogeneity of the patients in the trial, there was evidence that a single dose of AIC649 stimulates the patients' immune system as shown by increases in plasma levels of immune-regulating cytokines including IL-1β, IL-6, IL-8 and IFN-γ and reductions in IL-10 levels.

"These results from a first-in-human clinical trial are very encouraging. They clearly support our commitment to progressing the clinical development of AIC649, a promising candidate from our broad development pipeline of anti-infective compounds with the potential to induce functional cure in HBV-infected patients," said Dr. Holger Zimmermann, CEO of AiCuris Anti-infective Cures GmbH. "We are now preparing the production for further clinical trials with AIC649."

In a previous study in a woodchuck animal model of CHB, treatment with AIC649 induced a unique bi-phasic response pattern, and, in combination with Entecavir, led to a sustained loss of woodchuck hepatitis virus (WHV) DNA and surface antigen (WHsAg). The observed sustained loss of WHsAg and the induction of anti-WHsAg antibodies accompanied by cell mediated immune responses support the hypothesis that AIC649 induces a physiologically "concerted", reconstituted immune response to WHV[1], suggesting that AIC649 treatment may lead to functional cure in CHB patients.

About hepatitis B

Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV). The infection represents a major global health issue and is a significant occupational hazard, especially for healthcare workers. According to the World Health Organization (WHO), an estimated 257 million people worldwide are chronically infected with HBV (July 2018), and more than 880,000 people die each year due to complications from hepatitis B, including cirrhosis and liver cancer. Market experts have estimated the HBV market in the eight major pharmaceutical markets (US, France, Germany, Italy, Spain, UK, Japan, and China) will reach $3.0 billion in 2024 (RnR Market Research, 2016). There is a major medical need for new and innovative therapies to treat chronic infection with HBV as - despite numerous research activities - currently available therapies suppress the virus but can only cure the disease in a small percentage of patients.

About AIC649

AIC649 is a proprietary inactivated parapoxvirus particle preparation. It induces a natural, self-limiting immune response, enhancing appropriate immune responses against unrelated viruses. As a novel biological immunomodulator, AIC649 has the potential to offer a functional cure for HBV. AiCuris has successfully completed a clinical phase 1 trial with AIC649 in chronic HBV patients and is currently stepping up CMC production as well as the next steps of clinical development.

AiCuris报告在慢性乙型肝炎患者中使用免疫调节剂AIC649进行阳性1期临床试验结果

AiCuris报告使用免疫调节剂AIC649进行阳性1期临床试验结果
在慢性乙型肝炎患者中

单次静脉内剂量1期试验显示AIC649在所有剂量组中都是安全且耐受良好的
该试验提供了AIC649刺激慢性乙型肝炎患者免疫系统的证据
进一步试验研究AIC649诱导慢性乙型肝炎病毒(HBV)感染的功能性治疗的潜力是有必要的
德国伍珀塔尔,2018年9月3日 - 艾可鲁斯抗感染治疗有限公司,一家发现和开发针对传染病的药物的领先公司,宣布其首次在人体内进行单次递增剂量临床第一阶段试验的结果AIC649患有慢性乙型肝炎(CHB)患者。

随机,多中心,双盲,安慰剂对照的1期临床试验旨在评估单次上调静脉内剂量的AIC649在CHB患者中的安全性,耐受性和药效学。 32名患者在4个递增剂量组中随机分组。每组患者接受单剂量的AIC649或安慰剂,并监测84天。大多数患者是男性,HBeAntigen(HBeAg)阴性和HBV治疗天真。

单次静脉内剂量的AIC649在所有剂量组中都是安全且耐受良好的。没有剂量限制性毒性,并且在施用的最高剂量下未达到最大耐受剂量。尽管试验中患者存在异质性,但有证据表明,单剂量的AIC649刺激患者的免疫系统,如血浆中免疫调节细胞因子水平的增加,包括IL-1β,IL-6,IL-8和IFN-γ和IL-10水平的降低。

“首次在人体临床试验中取得的这些结果非常令人鼓舞。它们显然支持我们致力于推动AIC649的临床开发,AIC649是我们广泛开发的抗感染化合物的有希望的候选药物,具有诱导功能性治愈的潜力。感染HBV的患者,“AiCuris Anti-infective Cures GmbH首席执行官Holger Zimmermann博士说。 “我们现在正准备用AIC649进行进一步的临床试验。”

在以前的CHB土拨鼠动物模型研究中,用AIC649治疗诱导了独特的双相反应模式,并与恩替卡韦联合使用,导致土拨鼠肝炎病毒(WHV)DNA和表面抗原(WHsAg)持续丧失。观察到WHsAg的持续丧失和抗WHsAg抗体的诱导伴随细胞介导的免疫反应支持AIC649诱导对WHV的生理学“协同”,重建的免疫反应的假设[1],表明AIC649治疗可能导致功能性治愈在CHB患者中。

关于乙型肝炎

乙型肝炎是由乙型肝炎病毒(HBV)引起的可能危及生命的肝脏感染。感染是一个重大的全球健康问题,并且是一个重大的职业危害,特别是对医疗保健工作者。根据世界卫生组织(WHO)的统计,全球估计有2.57亿人长期感染HBV(2018年7月),每年因乙型肝炎并发症(包括肝硬化和肝癌)死亡的人数超过880,000人。市场专家估计,2024年八大医药市场(美国,法国,德国,意大利,西班牙,英国,日本和中国)的HBV市场将达到30亿美元(RnR Market Research,2016)。对于治疗HBV慢性感染的新型和创新疗法有一个主要的医学需求 - 尽管有许多研究活动 - 目前可用的疗法抑制病毒,但只能在一小部分患者中治愈该病。

关于AIC649

AIC649是一种专有的灭活副痘病毒颗粒制剂。它诱导自然的,自限性的免疫反应,增强针对不相关病毒的适当免疫反应。作为一种新型生物免疫调节剂,AIC649具有为HBV提供功能性治疗的潜力。 AiCuris已成功完成AIC649在慢性HBV患者中的临床1期临床试验,目前正在加强CMC生产以及临床开发的后续步骤。

AIC649是一种已知能诱导土拨鼠肝炎表面抗原(WHsAg)丧失并诱导产生抗WHsAg抗体的免疫调节剂,这表明 AIC649 可能让慢性乙型肝炎患者(pts)实现功能性治愈。

在加拿大多伦多举行的2018年全球肝炎峰会(Global Hepatitis Summit 2018)上,AiCuris公司的研究人员公布了部分该药正在进行的 1 期临床试验的部分数据。

这项随机,多中心,双盲,安慰剂对照试验旨在评估慢乙肝患者单递增剂量静脉注射AIC649的安全性,耐受性和药效学。

研究总共纳入了32名男性和女性,年龄为18至65岁,初治和经治乙型肝炎e抗原(HBeAg)阴性和阳性患慢乙肝患者作为受试对象。

在4个剂量组队列的每个队列中,8名患者接受单剂量AIC649(6名患者)或安慰剂(2名患者),随后进行84天的随访。

安全性评估包括总体耐受性,临床实验室检测和不良反应事件。在整个过程中评估HBV参数,基线和治疗后14天之间的免疫学参数。

AIC649治疗的患者(20 / 24,83.7%)报告的治疗紧急不良事件(TEAE)比安慰剂(8 / 8,100%)相对较少。没有接受AIC649用药的患者有与药物有关的,严重的或严重的TEAE。AIC649 对生命体征,心电图,血液学,临床化学或尿分析没有明显影响。没有肝脏炎症发生。

HBV DNA 和 HBsAg 水平在大多数患者中并没有实质性改变。然而,2名初治的患者(1名安慰剂,1名AIC649,剂量组3)在随访结束时显示 HBV DNA 明显减少。在安慰剂患者中,HBV DNA 低于检测限,但不能检测到抗-HBs抗体。AIC649 治疗的患者实现HBeAg消失获得抗HBe血清转换,尽管HBsAg水平不变,但抗-HBs Ab转为阳性。

在单次剂量的AIC649后,有证据表明先天性免疫的激活,IL-1b,IL-6,IL-8,IFN-γ增加,IL-10 血浆水平降低。无法建立明确的剂量 - 反应关系。只有IFN-γ在最高剂量组中显示一致的反应。CD4 T细胞效应物记忆群体似乎从剂量水平2开始向上一致地扩展。

综上,在所有剂量组中单次静脉内注射AIC649是安全的并且耐受性良好。尽管试验中患者存在异质性,但有证据表明单次剂量的AIC649可刺激先天性免疫的激活。
