Importance:

Individuals with Down syndrome (DS) are at high risk of developing Alzheimer disease due to an increased dose of the amyloid precursor protein gene, APP, which leads to increased levels of full-length APP and its products, including amyloid-β (Aβ). The liposome-based antiamyloid ACI-24 vaccine is intended to treat neurological disorders caused by misfolded Aβ pathological protein. However, the safety, tolerability, and immunogenicity of the ACI-24 vaccine among adults with DS have not been fully examined.

Objective:

To assess the safety and tolerability of the ACI-24 vaccine among adults with DS as well as its ability to induce immunogenicity measured by anti-Aβ immunoglobulin G titers.

Design, Setting, and Participants:

This multicenter double-blind placebo-controlled dose-escalation phase 1b randomized clinical trial was conducted at 3 US academic medical centers with affiliated Down syndrome clinics between March 30, 2016, and June 29, 2020. A total of 20 adults with DS were screened; of those, 16 adults were eligible to participate. Eligibility criteria included men or women aged 25 to 45 years with cytogenetic diagnosis of either trisomy 21 or complete unbalanced translocation of chromosome 21. Between April 27, 2016, and July 2, 2018, participants were randomized 3:1 into 2 dose-level cohorts (8 participants per cohort, with 6 participants receiving the ACI-24 vaccine and 2 receiving placebo) in a 96-week study. Participants received 48 weeks of treatment followed by an additional 48 weeks of safety follow-up.

Interventions:

Participants were randomized to receive 7 subcutaneous injections of ACI-24, 300 μg or 1000 μg, or placebo.

Main Outcomes and Measures:

Primary outcomes were measures of safety and tolerability as well as antibody titers.

Results:

Among 16 enrolled participants, the mean (SD) age was 32.6 (4.4) years; 9 participants were women, and 7 were men. All participants were White, and 1 participant had Hispanic or Latino ethnicity. Treatment adherence was 100%. There were no cases of meningoencephalitis, death, or other serious adverse events (AEs) and no withdrawals as a result of AEs. Most treatment-emergent AEs were of mild intensity (110 of 132 events [83.3%]) and unrelated or unlikely to be related to the ACI-24 vaccine (113 of 132 events [85.6%]). No amyloid-related imaging abnormalities with edema or cerebral microhemorrhage and no evidence of central nervous system inflammation were observed on magnetic resonance imaging scans. Increases in anti-Aβ immunoglobulin G titers were observed in 4 of 12 participants (33.3%) receiving ACI-24 (2 receiving 300 μg and 2 receiving 1000 μg) compared with 0 participants receiving placebo. In addition, a greater increase was observed in plasma Aβ1-40 and Aβ1-42 levels among individuals receiving ACI-24.

Conclusions and Relevance:

In this study, the ACI-24 vaccine was safe and well tolerated in adults with DS. Evidence of immunogenicity along with pharmacodynamic and target engagement were observed, and anti-Aβ antibody titers were not associated with any adverse findings. These results support progression to clinical trials using an optimized formulation of the ACI-24 vaccine among individuals with DS.

Abstract:

Pyroglutamate amyloid beta3–42 (pGlu-Abeta3–42), a highly amyloidogenic and neurotoxic form of Abeta, is N-terminally truncated to form a pyroglutamate and has recently been proposed as a key target for immunotherapy. Optimized ACI-24, a vaccine in development for the treatment and prevention of Alzheimer’s disease, focuses the antibody response on the first 15 N-terminal amino acids of Abeta (Abeta1–15). Importantly, clinical data with an initial version of ACI-24 incorporating Abeta1–15, established the vaccine’s safety and tolerability with evidence of immunogenicity. To explore optimized ACI-24’s capacity to generate antibodies to pGlu-Abeta3–42, pre-clinical studies were carried out. Vaccinating mice and non-human primates demonstrated that optimized ACI-24 was well-tolerated and induced an antibody response against Abeta1–42 as expected, as well as high titres of IgG reactive with pyroGlu-Abeta. Epitope mapping of the polyclonal response confirmed these findings revealing broad coverage of epitopes particularly for Abeta peptides mimicking where cleavage occurs to form pGlu-Abeta3–42. These data are in striking contrast to results obtained with other clinically tested Abeta targeting vaccines which generated restricted and limited antibody diversity. Taken together, our findings demonstrate that optimized ACI-24 vaccination represents a breakthrough to provide a safe immune response with a broader Abeta sequence recognition compared to previously tested vaccines, creating binders to pathogenic forms of Abeta important in pathogenesis including pGlu-Abeta3–42.

Reduction of β-amyloid plaques in brain of transgenic mouse model of Alzheimer’s disease by EFRH-phage immunization

3区 · 医学

Article

作者: Freddy Van Leuven ; Dan Frenkel ; Ilse Dewachter ; Beka Solomon

Antibodies to the epitope EFRH, representing residues 3-6 within the beta-amyloid (Abeta) sequence, were previously shown to affect the solubility and disaggregation of Abeta fibrils in vitro. Here, we describe a novel method of immunization, using as antigen the EFRH peptide displayed on the surface of the filamentous phage. The EFRH phage evoked effective auto-immune antibodies in amyloid precursor protein [V717I] (APP[V717I]) transgenic mice that recapitulate the amyloid plaques and vascular pathology of Alzheimer's disease (AD). The immunization provoked a considerable reduction in the number of Abeta amyloid plaques in the brain of the transgenic mice and may serve as the basis for anti-Abeta vaccine.

Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “AC Immune’s portfolio of active immunotherapies for precision prevention of neurodegeneration continues to advance in clinical development. Our interim Phase 2 data on ACI-7104.056, our wholly owned a-syn active immunotherapy, demonstrated strong immunogenicity and a favorable safety profile in early Parkinson’s disease patients, further supporting its best-in-class characteristics. Our two partnered active immunotherapy programs, ACI-24.060 and ACI-35.030, also advanced well in their respective ongoing Phase 2 trials. Furthermore, we highlighted progress with our promising early-stage assets in presentations of preclinical data at AD/PD™ 2025, including Morphomer® small molecule drugs targeting a-syn and Tau, and Morphomer®-antibody drug conjugates (morADC) our new class of drug candidates for neurodegenerative diseases.” “AC Immune is well financed into Q1 2027, without including significant potential milestones. We are moving towards several value-inflection points throughout 2025, including pharmacodynamic and biomarker data on ACI-7104.056 and potential initiation of Part 2 of the Phase 2 VacSYn trial, reaching the 12-month treatment timepoint for all the Alzheimer’s disease (AD) cohorts (including AD3 where enrollment was completed in December 2024) of the Phase 2 ABATE trial of ACI-24.060, and further developments across our early-stage pipeline.” Q1 2025 and Subsequent Highlights: Additional interim safety and positive immunogenicity data from the Phase 2 VacSYn clinical trial evaluating ACI-7104.056, AC Immune’s wholly-owned anti-a-syn active immunotherapy candidate, for the treatment of patients with early PD. Antibody responses were rapidly induced against the target antigen after 2 immunizations and were further boosted by each subsequent immunization.Treatment with ACI-7104.056 induced an increase in anti-a-syn antibodies on average more than 20-fold higher than the placebo background level after four immunizations.Based on further interim results to be reported later in 2025, including pharmacodynamic and biomarker data, AC Immune may decide to initiate Part 2 of VacSYn, with the aim of establishing early proof-of-concept and identification of disease-specific biomarkers for rapid transition into a pivotal study.

AD疫苗：阿尔茨海默病的预防新希望

-01-引言阿尔茨海默病（Alzheimer′s disease，AD）是发生于老年期和老年前期的神经系统退行性疾病，起病隐袭且病程呈进行性发展，临床表现以获得性认知功能损害为核心症状，涉及记忆、学习、定向、理解、判断、计算、语言和视空间等认知域，不同程度地影响日常生活能力及社会职业功能，最终进展为全面性痴呆。根据GBD数据，2019年全球AD及相关痴呆的患病人数达到5162万，总体患病率为 667.2/10万，年龄标化患病率为 682.5/10万。同年，我国 AD 及相关痴呆总人数为1314 万，大约占全球AD患者总人数的25.5%，我国AD及相关痴呆总体患病率为924.1/10万，年龄标化患病率为788.3/ 10万。目前我国国家药品监督管理局批准用于治疗 AD的一线药物包括胆碱酯酶抑制剂，如多奈哌齐、卡巴拉汀等，以及N‑甲基‑D‑门冬氨酸（NMDA）受体拮抗剂美金刚。2019年国家药品监督管理局有条件批准了甘露特钠胶囊上市注册申请，用于治疗轻度至中度AD。2024 年 1 月仑卡奈单抗（lecanemab）注射液获国家药品监督管理局批准上市，用于治疗由 AD引起的 MCI和轻度痴呆。然而，这些方法多半是对症治疗，近一半的患者对现有药物治疗的效果不满，其次是药物价格贵。因此，亟须针对这些问题和痛点进一步改善我国AD患者的治疗现状。主动免疫疗法，即疫苗接种，是针对淀粉样β（Aβ）的阿尔茨海默病（AD）研究最彻底的治疗方法之一。在20多年前， AN1792疫苗在临床进行了研究，虽然因为毒性问题没有继续开发，然而人们也从中看到了疫苗预防AD的潜力。AD的疫苗预防可能改变阿尔茨海默症目前的困境。-02-一、AD的发病机制目前，AD研究的主流观点认为，AD的发病机制是Aβ与Tau蛋白的协同作用结果：Aβ的毒性级联反应Aβ由淀粉样前体蛋白（APP）裂解产生，其可溶性寡聚体（AβOs）是神经毒性的“真凶”。它们攻击突触功能，触发炎症，并诱导Tau蛋白过度磷酸化，形成NFTs。研究表明，可溶性AβOs比斑块与认知衰退的相关性更强。Tau蛋白的雪崩效应Tau蛋白过度磷酸化后脱离微管，形成NFTs，破坏神经元运输系统。这种病理过程存在“交叉播种效应”：AβOs加速Tau病变扩散，而NFTs恶化神经元死亡。炎症与免疫失衡小胶质细胞和星形胶质细胞的慢性炎症反应进一步破坏脑内稳态，形成“病理恶性循环”。-03- 二、疫苗：AD预防的免疫堡垒传统药物治疗聚焦症状缓解，疫苗则直击疾病上游，提供“治未病”的可能。其核心策略包括：1. 精准打击Aβ毒性寡聚体AD疫苗通过诱导抗体中和AβOs，阻止其破坏突触并触发炎症。动物模型显示，靶向AβOs的疫苗可显著延缓认知衰退。2. Th2极化理想疫苗需诱导抗炎性Th2免疫反应，避免促炎性Th1反应加重脑损伤。佐剂选择是关键：传统铝佐剂（Alum）可能引发炎症副作用，而新型Th2偏向佐剂（如TLR9激动剂）可能解决上述问题。3. 被动免疫的局限性单克隆抗体（如Lecanemab、Donanemab和Aducanumab）虽可快速清除Aβ，但需频繁注射且成本高昂。主动免疫疫苗通过激发自身免疫记忆，提供长期保护，更适合预防性应用。-04-三、AD疫苗的开发现状AN-1792是第一个人类Aβ主动免疫疗法，由合成全长人类Aβ42和佐剂QS-21组成。AN-1792的1期临床研究包括372名轻度至中度AD患者。第1阶段试验的结果表明，该疫苗可诱导对Aβ42的抗体反应，并可清除大脑中的斑块。然而，在II期试验中，由于患者发展为脑膜炎，临床试验暂停。尽管AN-1792临床试验有副作用，但该研究的结果鼓励开发新的主动抗Aβ免疫治疗方法。 CAD106疫苗由诺华公司研发，通过诱导抗体产生来减少β淀粉样斑块。该疫苗由截短的β-淀粉样蛋白片段（Aβ1-6）组成，以避免T细胞活化。在第一阶段试验的52周内没有出现脑膜炎的迹象。然而由于缺乏疗效，目前已停止开发。ABvac40疫苗由Araclon Biotech开发，其结构针对Aβ40的C末端，包含与KLH偶联的Aβ33–40。ABvac40 2023年公布了II期临床结果，达到了主要终点，与安慰剂相比，ABvac40治疗可将疾病进展的速度减慢38%。ACI-24疫苗由AC Immune开发，包含Aβ1-15表位，不包括T细胞表位，以避免T细胞反应。ACI‐24的 II期临床试验由于低免疫原性撤回，正在继续优化；新分子ACI-24.060被武田以里程碑总价22亿美元引进。UB-311疫苗由United Biomedical开发，含有Aβ1-14表位，并与辅助T细胞肽表位融合，利用CpG作为佐剂。肽混合物将诱导B细胞反应，同时避免T细胞的炎症反应。2023年发表的2期研究结果显示，UB-311治疗达到了主要终点，该疗法具有良好安全性、耐受性，并产生稳健的免疫应答。-05-四、AD疫苗研发开发的挑战虽然AD疫苗展现出缓解AD进展的前景，但AD疫苗研发仍面临多重“拦路虎”：1. 免疫衰老（Immunosenescence）:老年人群免疫应答低下，疫苗需克服T细胞功能衰退和慢性炎症背景。2. 血脑屏障（BBB）阻碍98%的大分子抗体无法穿透BBB，新型的递送技术是破局方向。3. 患者异质性：AD亚型复杂，需基于生物标志物（如Aβ-PET、脑脊液pTau）细分人群，实现精准免疫。4. 临床试验设计困境：AD进程缓慢，需超长随访（10年以上）和替代终点（如Aβ清除率）加速验证。5. 安全性红线：避免诱发自身免疫性脑膜炎（如AN1792）或微出血，是疫苗设计的核心原则。-06-五、未来方向：多靶点联合与技术创新1. 靶向“Aβ-Tau轴”复合疫苗：同时激活针对AβOs和异常Tau的免疫应答，阻断病理级联。2. 新型递送系统：鼻内疫苗、DC细胞疫苗或外泌体载体可能增强脑内抗体渗透。3. 佐剂革命：开发纯Th2极化佐剂，平衡免疫激活与安全性。4. 人工智能助力设计：AI预测抗原表位和抗体结合构象，缩短疫苗开发周期。-07-结语AD是一种严重影响人类健康的多因素异质性神经退行性疾病，目前还没有能够治愈的药物，已获得批准的药物也只能减缓疾病的进展。因此，AD最好在发生严重认知障碍之前进行早期干预，AD预防有潜力可能实现延迟或预防AD痴呆的治疗目标。AD疫苗研发虽荆棘密布，但随着对病理机制的解码和技术迭代，未来十年或有革命性疫苗问世。“疫苗或许不能逆转时光，但能让我们优雅地老去。”愿未来AD将不再成为困扰我们的严重疾病。参考资料：1.
