AC Immune SA Initiates Final Cohort in Ongoing Phase 1b/2 ABATE Trial of Anti-Abeta Active Immunotherapy to Treat Alzheimer's Disease AC Immune SA dosed the first patients in Cohort AD4 in the ongoing Phase 1b/2 ABATE trial. Treatment of first patient in Cohort AD4 in ABATE trial triggers $12 million milestone payment. ABATE is assessing ACI-24 in subjects with prodromal AD and in adults with Down syndrome (DS). AD4 includes subjects with prodromal AD. ACI-24 is an anti-Abeta active immunotherapy candidate designed to induce a robust antibody response against the toxic forms of Abeta believed to drive plaque formation and AD progression. By inducing plaque clearance and efficiently inhibiting plaque formation in the brain, ACI-24 has the potential to delay or slow AD progression. ACI-24 is being investigated in the ongoing ABATE randomized, double-blind, placebo-controlled Phase 1b/2 trial to assess its safety, tolerability, immunogenicity and pharmacodynamic effects. Data so far show that ACI-24 is generally safe and well tolerated, and that it has generated anti-Abeta antibody responses at all tested doses. Cohorts AD1, AD2 and AD3 enrolled a total of 74 patients who received ACI-24 at escalating dose levels. The 12-month data readouts from Cohorts AD1, AD2 and AD3 are expected later in Second Quarter 2026. Cohort AD4 will include an initial group of 36 patients treated for 12 months, with follow-up of 6 months, significantly expanding the safety and biomarker efficacy data set. A subsequent expansion of the AD4 cohort could potentially see the total number of subjects reach approximately 112 patients. AC Immune is responsible for conducting the ABATE trial. Following the potential option exercise, Takeda would conduct and fund all further clinical development and be responsible for all global regulatory activities as well as worldwide commercialization. Under the terms of the agreement with Takeda, AC Immune received an upfront payment of $100 million and is eligible to receive an option exercise fee and additional potential development, commercial and sales-based milestones of up to approximately $2,100 million, if all related milestones are achieved over the course of the agreement. Upon commercialization, AC Immune will be entitled to receive tiered double-digit royalties on worldwide net sales. The ABATE randomized, double-blind, placebo-controlled Phase 1b/2 trial of ACI-24 for treatment of Alzheimer’s disease (AD) continues fully blinded (NCT05462106). Enrolled patients are required to have a diagnosis of prodromal AD: MCI due to AD according to the National Institute on Aging Alzheimer’s Association (NIA-AA) criteria, and a PET scan at screening must be consistent with the presence of amyloid pathology. Patients will be randomized to one of several doses of ACI-24 or placebo. Following multiple data safety monitoring board (DSMB) reviews, no safety concerns have been raised to date, consistent with previous results. Very encouraging immunogenicity has been shown with clear evidence of anti-Abeta antibody responses against toxic Abeta species observed in the blinded data. Annonce • Mar 20
Ac Immune Sa Presents First in Vivo Images of Brain Tdp-43 Pathology from Phase 1 Trial of Pet Tracer Aci-19626 AC Immune SA, a clinical-stage biopharmaceutical company pioneering precision therapeutics for neurodegenerative diseases, announced the presentation of Phase 1 data including the first in vivo images of TDP-43 pathology in the human brain, detected using its first-in-class positron emission tomography (PET) tracer ACI-19626, at the International Conference on Alzheimer’s and Parkinson’s Disease (AD/PD 2026). Initial data from the Phase 1 trial support ACI-19626’s potential to detect pathological TDP-43 in the brains of patients with TDP-43 proteinopathies, enabling a precision medicine approach to multiple neurodegenerative diseases. Specifically, PET scans with ACI-19626 showed that tracer uptake was significantly higher in key regions of the brain in patients with frontotemporal dementia (FTD) due to mutated C9orf72 than in the brains of healthy subjects. Regions with higher tracer uptake included subcortical and cortical regions of the brain where TDP-43 pathology is expected based on post-mortem neuropathology studies. ACI-19626 showed good safety and tolerability, a dosimetry profile within accepted limits, and rapid brain uptake and washout, indicating a pharmacokinetic (PK) profile suitable for human brain imaging and potentially pharmacodynamic analysis of therapeutics targeting TDP-43 pathology. TDP-43 is the main component in inclusions found in the brains of people with FTD, amyotrophic lateral sclerosis (ALS) and limbic-predominant age-related TDP-43 encephalopathy (LATE), as well as a co-pathology in Alzheimer’s disease (AD) and Parkinson’s disease (PD). These conditions share many of the same clinical signs and symptoms, making differential diagnosis a difficult and lengthy process in the absence of reliable biomarkers. The Phase 1, first-in-human trial (Clinicaltrials.gov: NCT06891716) is in two parts. Part 1 is investigating ACI-19626 in healthy volunteers and patients with genetic FTD and is expected to be completed in First Half 2026. The Part 2 expansion may include up to 30 patients with FTD, ALS or LATE. Exploration of ACI-19626 binding in additional patient populations including ALS is ongoing. Annonce • Feb 25
AC Immune Initiates Phase 1 Clinical Trial of NLRP3 Inhibitor AC Immune SA announced that the first participant has been dosed in a Phase 1 clinical trial of ACI-19764, an orally administered small molecule inhibitor of the NLRP3 inflammasome. Targeting the NLRP3 inflammaome provides an opportunity to reduce the chronic inflammation thought to be associated with disease progression in multiple inflammatory disorders, metabolic diseases, and neurological diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. The Phase 1 trial will investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ACI-19764 in healthy volunteers. The study is dividend into two parts. Part A will evaluate single ascending doses while Part B will examine multiple ascending doses. The trial is being conducted in Europe. Primary outcome measures include the safety and tolerability of ACI-19764., as well as its pharmacokinetics in plasma and cerebrospinal fluid. A secondary outcome measure will assess target engagement (inhibition of IL-1) and exploratory endpoints will include the influence of ACI-19764 on fluid biomarkers of the immune system, among others. Initial data from the Phase 1 trial are expected in the second half of 2026. ACI-19764 has demonstrated a highly competitive profile in extensive preclinical studies, with optimal brain penetrant in animal models, high potency and selectivity in assays including whole human blood and in several in vivo models, and an excellent safety and tolerability profile. In a mouse model of diet-induced obesity (DIO), ACI-19764 showed excellent weight control both alone and in combination with semaglutide, as well as reductions in activation of both microglia and astrocytes. These preclinical data position ACI-19764 competitively among the best-in-class NLRP3 inhibitors for CNS indications. ACI-19764 is an orally available, highly brain penetrant, small molecule drug candidate which specifically inhibits the NLRP3 inhibitor. Annonce • Feb 18

Ac Immune Sa Announces Results from Phase 1B/2A Trial of Anti-Ptau Active Immunotherapy from Ac Immune Sa Published in Ebiomedicine AC Immune SA announced the peer-reviewed publication in eBioMedicine of results from the completed Phase 1b/2a trial of active immunotherapy ACI-35.030's (JNJ-2056) partnered with Janssen Pharmaceuticals Inc., a Johnson & Johnson company. ACI-35.030 generated a rapid, robust and durable polyclonal response against pathological forms of Tau including phosphorylated Tau (pTau) and brain-derived Tau (enriched paired helical filament, ePHF). There were no clinically relevant safety or tolerability observations for either ACI-35.030 or JACI-35.054. The publication is entitled "Safety and immunogenicity of two Tau-targeting active immunotherapies, ACI-35.030 and JACI-35. May4, in participants with early Alzheimer's disease: a Phase 1b/2a, multicentre, double-blind, randomized, placebo-controlled study" and reports the following key findings from the completed trial (NCT04445831): ACI-35.030 is based on AC Immune's proprietary SupraAntigen®? technology which anchors the pTau peptide in a liposome and also incorporates non-Tau T-cell epitopes and adjuvants. JACI-35.074 covalently linked the immunogen to the carrier protein CRM197 and was mixed with adjuvants. Both active immunotherapies used the same target pTau peptide sequence. ACI-35.03 (JNJ-64042056) is an investigational active immunotherapy designed using AC Immune's SupraAntigen®? platform. Its liposomal formulation incorporates a conformationally-constrained, membrane bound target peptide, phosphorylated Tau, in addition to adjuvants and non-Tau T-helper peptides. Immunization with ACI-35.030 has been shown in a recent Phase 1b/2a clinical trial to rapidly elicit antibodies after the first injection against extracellular pathological pTau in 100% of patients with early Alzheimer's disease. Importantly, the antibody response was observed at all tested doses and induced a rapid and sustained response against pathological Tau, while requiring less frequent dosing to maintain titers as compared to monoclonal antibodies. Safety and rapid, durable responses are key advantages of active immunotherapies, which make them particularly well suited to the long-term treatment needed to achieve precision prevention.

Ac Immune Reports Positive Interim Results from Phase 2 Trial of Aci-7104.056 Active Immunotherapy in Early Parkinson’S Disease AC Immune SA announced positive interim safety and immunogenicity data from the Phase 2 VacSYn clinical trial evaluating ACI-7104.056, its wholly owned anti-alpha-synuclein (a-syn) active immunotherapy candidate, for the treatment of patients with early Parkinson’s disease (PD). VacSYn is an adaptive, placebo-controlled, and biomarker-based Phase 2 study in patients with early PD, consisting of two parts with a seamless transition. Part 1 includes initial analyses from over 30 patients randomized to receive ACI-7104.56 or placebo at a ratio of 3:1. To date, no clinically relevant safety issues have been reported other than transient injection site reactions (49%) and headaches (18%). Interim results show positive antibody responses were effectively induced against the target antigen at week 6 after 2 immunizations and were strongly boostable. Treatment with ACI-7104.056 induced an increase in anti-a-syn antibodies on average 16-fold higher than the placebo background level after three immunizations. Based on further interim results to be reported in H1 2025 including pharmacodynamic data, AC Immune may decide to initiate Part 2 of VacSYn with up to 150 patients. Patients from Part 2 will also be evaluated for progression of motor and non-motor symptoms of the disease, as well as digital, imaging, and fluid biomarkers. The aim is to establish early proof-of-concept and identification of disease-specific biomarkers for rapid transition into a pivotal study. ACI-7104.056 is an optimized formulation of its clinically validated anti-a-syn predecessor active immunotherapy which generated a target-specific antibody response against pathological oligomeric a-syn to inhibit spreading and downstream neurodegeneration in early Parkinson’s disease. The accumulation of alpha-synuclein protein aggregates has been shown to cause inflammatory stress in cells and contribute to the degeneration of neurons in the brain. It has been known to play a key role in the development of neurodegenerative diseases such as Parkinson’s Disease. Previous clinical studies showed the predecessor candidate produced a strong and boostable antibody response with evidence of target engagement and a signal of clinical efficacy. Annonce • Aug 07

New minor risk - Profitability The company is currently unprofitable and not forecast to become profitable over the next 3 years. Trailing 12-month net loss: CHF55m Forecast net loss in 3 years: CHF20m This is considered a minor risk. Companies that are not profitable are more likely to be burning through cash and less likely to be well established. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. Without profits, the company is under pressure to grow significantly while potentially having to reduce costs and possibly needing to take on debt or raise capital to remain afloat. Currently, the following risks have been identified for the company: Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (CHF20m net loss in 3 years).

New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 28% This is considered a minor risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings.

AC Immune SA Receives FDA Fast Track Designation for Anti-Amyloid-Beta Active Immunotherapy, ACI-24 060, to Treat Alzheimer's Disease AC Immune SA announced that it has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for its wholly-owned anti-amyloid beta (Abeta) active immunotherapy (vaccine)-candidate, ACI-24.060, for treatment of Alzheimer's disease. This follows FDA clearance of the Investigational New Drug (IND) application enabling expansion to the USA of the ongoing Phase 1b/2 ABATE study of ACI- 24.060 in patients with AD and individuals with DS. Furthermore, the first individual with DS has been dosed in ABATE. This regulatory progress underscores the attraction of an active immunotherapy targeting toxic species of Abeta. By inducing a polyclonal response including antibodies against both oligomeric Abeta and pyroglutamate-Abeta, ACI-24.060 targets the same toxic species as disease modifying anti-Abeta monoclonal antibodies that slowed AD progression in Phase 3 clinical trials. As ACI-24.060, created using our SupraAntigen(R) platform, specifically targets the most toxic forms of Abeta, we believe it may offer best-in-class efficacy with all the potential advantages in safety, administration and distribution that can be expected from a vaccine. We look forward to showing in first half 2024 the effect of ACI-24.060 on amyloid plaque reduction, a surrogate marker for disease modification. The ABATE study is a Phase 1b/2, multicenter, adaptive, double-blind, randomized, placebo-controlled study to assess the safety, tolerability, immunogenicity, and pharmacodynamic effects of ACI-24.060 in subjects with prodromal Alzheimer's disease and in adults with Down syndrome. All participants in the trial must have brain Abeta pathology confirmed by a positron emission tomography (PET) scan. Recent clinical studies and FDA approvals have validated Abeta as a disease modifying therapeutic target in AD and are supportive of Abeta PET imaging as a surrogate marker of efficacy. The trial begins with a dose escalation phase in AD patients, during which various doses/dosing regimens may be evaluated, and also includes individuals with DS. About AD in Down syndrome Individuals with Down syndrome (DS) have a third copy of all or part of chromosome 21, which contains the gene that codes for amyloid-precursor protein (APP). Overproduction of APP is believed to cause the accumulation of Abeta plaques. Virtually all individuals with DS will develop Abeta plaques and AD(1), with DS-related AD sharing a similar pathophysiology and biomarkers with other forms of genetic AD. Given the more predictable onset and progression of symptoms in DS-related AD, AC Immune believes ABATE's results will offer crucial insights into the ability of ACI-24.060 active immunotherapy to modulate neurodegeneration at its earliest stages and offer this population a much needed therapeutic option.

AC Immune’s ACI-24.060 Anti-Amyloid Beta Vaccine for Alzheimer’s Shows Positive Initial Interim Safety and Immunogenicity in Phase 1b/2 ABATE Trial AC Immune SA announced the first interim safety, tolerability and immunogenicity findings from the Phase 1b/2 ABATE trial of its anti-amyloid-beta (Abeta) vaccine ACI-24.060 in patients with prodromal Alzheimer’s disease (AD). ABATE will now be expanded, as planned, to include individuals with Down syndrome (DS) and to evaluate higher doses in Alzheimer’s patients. Targeting Abeta using antibodies has recently been validated with FDA approvals of new monoclonal antibody treatments for patients with AD. By eliciting polyclonal anti-Abeta antibodies, the ACI-24.060 anti-Abeta vaccine development program aims to ultimately deliver significant benefits to patients, their caregivers, and healthcare systems in terms of potential safety and tolerability, low frequency dosing, low overall costs and durable responses. Early results from the first cohort of AD patients in ABATE showed that low dose ACI-24.060 could elicit an anti-Abeta antibody response as soon as week 6 (2 weeks after the second injection). The data show that ACI-24.060 vaccination has been safe and well tolerated to date. As a result, dosing in ABATE’s second, higher dose AD cohort has now begun and the trial is cleared to begin screening individuals with DS for part 2 of the study. The ABATE study is a Phase 1b/2, multicenter, adaptive, double-blind, randomized, placebo-controlled study to assess the safety, tolerability, immunogenicity, and pharmacodynamic effects of ACI-24.060 in subjects with prodromal Alzheimer’s disease and in adults with Down syndrome. All participants in the trial must have brain Abeta pathology confirmed by a positron emission tomography (PET) scan. The trial begins with a dose escalation phase in AD patients, during which various doses/dosing regimens may be evaluated, and also includes individuals with DS. ACI-24.060, derived from AC Immune’s SupraAntigen® platform, has been shown in preclinical studies to induce a strong polyclonal antibody response that matures and is maintained against both oligomeric and pyroglutamate-Abeta species, key pathological forms of Abeta believed to drive Abeta plaque formation and disease progression. ACI-24.060 is designed to enhance the formation of broad-spectrum protective antibodies with the same safety and tolerability previously demonstrated in the ACI-24 program in Phase 1 and 2 trials. This investigational candidate has the potential to efficiently inhibit plaque formation and increase plaque clearance, and thereby may reduce or prevent disease progression.
