Early expression of capsule during Bacillus anthracis germination

Article

作者: Goossens, Pierre L ; Tournier, Jean-Nicolas ; Mock, Michèle ; Fastenackels, Solène

Bacillus anthracis is a spore-forming bacterium that produces two major virulence factors, a tripartite toxin with two enzymatic toxic activities and a pseudo-proteic capsule. One of the main described functions of the poly-gamma-d-glutamate capsule is to enable B. anthracis bacilli to escape phagocytosis. Thus, kinetics of expression of the capsule filaments at the surface of the emerging bacillus during germination is an important step for the protection of the nascent bacilli. In this study, through immunofluorescence and electron microscopic approaches, we show the emergence of the capsule through a significant surface of the exosporium in the vast majority of the germinating spores, with co-detection of BclA and capsular material. This suggests that, due to an early capsule expression, the extracellular life of B. anthracis might occur earlier than previously thought, once germination is triggered. This raises the prospect that an anti-capsular vaccine may play a protective role at the initial stage of infection by opsonisation of the nascent encapsulated bacilli before their emergence from the exosporium.

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.

AC Immune Receives Second Milestone Payment Following Progress in Phase 2b ReTain Trial of ACI-35.030 in Preclinical Alzheimer’s Disease

LAUSANNE, Switzerland I September 17, 2024 I AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision therapeutics for neurodegenerative diseases, today announced that it will receive the second ReTain-related milestone payment (CHF 24.6 million) under its agreement with Janssen Pharmaceuticals, Inc. (Janssen), a Johnson & Johnson company. The milestone payment has been triggered by the rapid rate of prescreening in the potentially registrational Phase 2b ReTain trial investigating active-immunotherapy candidate ACI-35.030 (now called “JNJ-2056”) to treat preclinical (pre-symptomatic) Alzheimer’s disease (AD). With last December’s milestone payment, this brings the total milestone payments received for ACI-35.030 related to this trial to CHF 40 million. Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “This early milestone demonstrates that the medical community and members of the public believe, as we do, that second generation therapeutics for Alzheimer’s disease, like our active immunotherapy targeting pathological phosphorylated-Tau protein (pTau), may provide an important benefit to those diagnosed early, prior to the development of disease symptoms. Early diagnosis and treatment are needed to combat neurodegeneration. “This payment also re-affirms the quality and productivity of AC Immune’s technology platforms and drug development capabilities. We have now received a total of approximately CHF 425 million in milestone and upfront payments from all of our collaboration deals to date, and there are outstanding potential milestone payments exceeding CHF 4.3 billion, plus royalties on potential sales. Importantly, in these challenging financial markets, this milestone payment adds to our already solid financial position, providing us with three years of cash for operations, in which time we expect to achieve several potentially transformational milestones.” JNJ-2056 received Fast Track designation from the U.S. Food and Drug Administration (FDA) in July, an important recognition of its differentiation and its potential value for patients. It is the second active immunotherapy from AC Immune to achieve this regulatory milestone, after ACI-24.060, which targets Abeta. AC Immune’s PI-2620 Tau-PET diagnostic, which is in Phase 3 development, also received Fast Track designation this August. ACI-35.030 has been shown in Phase 1b/2a clinical testing to induce an antibody response targeting pTau while sparing normal endogenous forms of Tau. ReTain has attracted a high level of interest among potential participants with the rate of prescreening outperforming expectations. “The Phase 2b ReTain trial is a potentially important step in the fight against neurodegeneration, as it is the first time any active immunotherapy is being tested in the preclinical AD population. Active immunotherapies like ACI-35.030 could offer therapeutic advantages, together with improved convenience and access, and the recent Fast Track designation is an important recognition of its potential value for patients,” Dr. Pfeifer said. About the Phase 2b ReTain Study (ClinicalTrials.gov Identifier: NCT06544616 ) The Phase 2b ReTain trial is a potentially registration-enabling randomized, multicenter, double-blind, placebo-controlled clinical study in participants with preclinical AD to assess the clinical effect of active immunization with JNJ-64042056 (JNJ-2056). It is designed to test the hypothesis that JNJ-2056 has a disease-modifying effect that can delay or prevent the onset of cognitive impairment or other clinical symptoms in individuals with preclinical AD through inhibition of seeding and spreading of pathological Tau. The study will include approximately 500 participants with preclinical AD (cognitively normal, Tau positive), who will be randomized in a 1:1 ratio to a single dose level of JNJ-2056 or placebo and administered as intramuscular injections for a maximum of 4 years. It is currently being conducted at more than 40 clinical trial sites in the U.S., Japan, UK and Australia, and more are expected to open shortly. The primary endpoint will measure cognitive decline as assessed by the Preclinical AD Cognitive Composite 5 (PACC-5) score. The key secondary efficacy endpoint will assess the effect of JNJ-2056 on the propagation and/or accumulation of Tau pathology compared with placebo, as measured by Tau PET imaging. The ReTain trial is fully funded and conducted by Janssen Pharmaceuticals, Inc. (Janssen), a Johnson & Johnson company, pursuant to a global license, development and commercialization agreement. About ACI-35.030 (JNJ-2056) ACI-35.030, derived from AC Immune’s SupraAntigen® platform, has been shown in clinical studies to induce a strong polyclonal antibody response that matures and is maintained against key pathological forms of Tau believed to drive Tau aggregation and disease progression. ACI-35.030 is designed to enhance the formation of broad-spectrum protective antibodies against pTau. This investigational candidate has the potential to reduce pathological Tau spreading in the early stages of AD, and thereby may reduce or prevent disease progression. About AC Immune SA AC Immune SA is a clinical-stage biopharmaceutical company and a global leader in precision prevention for neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and NeuroOrphan indications driven by misfolded proteins. The Company’s two clinically validated technology platforms, SupraAntigen® and Morphomer®, fuel its broad and diversified pipeline of first- and best-in-class assets, which currently features sixteen therapeutic and diagnostic programs, including five in Phase 2 development and one in Phase 3.

AC Immune’s PI-2620 Tau-PET Diagnostic in Phase 3 Receives Fast Track Designation in Three Neurodegenerative Conditions

AC Immune’s PI-2620 Tau-PET Diagnostic in Phase 3 Receives Fast Track Designation in Three Neurodegenerative Conditions PI-2620 is in Phase 3 development in Alzheimer’s disease by AC Immune’s partner, LMIThis Fast Track designation applies across Alzheimer’s disease, progressive supranuclear palsy, and corticobasal degenerationFollows two previous Fast Track designations for ACI-35.030 and ACI-24.060 active immunotherapiesAffirms AC Immune’s leadership and commitment to bringing precision medicine to the management of neurodegenerative diseases Lausanne, Switzerland, August 28, 2024 – AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision therapeutics for neurodegenerative diseases, today announced that its partner Life Molecular Imaging (LMI) has received Fast Track Designation for the Tau positron emission tomography (PET) diagnostic, [18F]PI-2620, from the U.S. Food and Drug Administration (FDA) in three neurodegenerative conditions. Fast Track designation for [18F]PI-2620 has been granted for clinical development in Alzheimer’s disease (AD), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). The FDA’s Fast Track program is designed to accelerate the development and review of drugs that address serious conditions and fulfill unmet medical needs. This designation underscores the broadening view in the medical community that early and accurate diagnoses of neurodegenerative disease may lead to improved outcomes, thanks to emerging treatments. PI-2620 is a next-generation PET imaging agent currently in Phase 3 clinical development for detecting Tau pathology in Alzheimer's disease. The compound is also being investigated in other neurodegenerative diseases by many academic researchers and in drug development trials. Tau proteins are a hallmark of several neurodegenerative disorders including AD, PSP, CBD, and frontotemporal lobar dementia (FTLD), and accurately imaging the pathology could significantly enhance disease diagnosis and improve patient care. Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “Fast Track designation for PI-2620 is an important reflection of its potential to accurately diagnose Alzheimer’s and other neurodegenerative diseases. Early diagnosis of these conditions will be key for effective treatment before irreversible damage occurs, and is an essential element in our goal of achieving precision prevention. The FDA has previously granted Fast Track status to two of our active immunotherapies in Phase 2 development, ACI-35.030 and ACI-24.060, which target phospho-Tau and Abeta, respectively. The designation for PI-2620 is a further recognition of AC Immune’s drug discovery and development platform and of how we, together with our partners, continue to drive innovation.” About PI-2620PI-2620 was discovered and developed as part of a research collaboration between AC Immune and LMI. LMI has the exclusive, worldwide license for research, development and commercialization of Tau-PET tracers generated within the discovery program. It has demonstrated robust brain uptake and fast wash-out in non-target regions, a broad imaging window between 30- and 90-minutes post-injection for AD, and excellent reproducibility between test and retest scans. The absence of significant off-target binding enables PI-2620 to detect and quantify early Tau deposition in the brain, a hallmark of neurodegenerative diseases. PI-2620 is currently under investigation in several clinical studies as a targeted radiopharmaceutical for the detection of Tau deposits in the human brain. PI-2620 also shows promise for non-AD tauopathies like progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS).
