AC Immune Reports Third Quarter 2023 Financial Results and Provides a Corporate Update

• Results from amyloid plaque reduction analysis (Abeta-PET) after 6 months of treatment with ACI-24.060 in ABATE Phase 1b/2 study on track for H1 2024
• ACI-24.060 ABATE interim safety and immunogenicity data in Alzheimer’s disease (AD) expected by year-end
• ACI-7104.056 alpha-synuclein active immunotherapy in Phase 2 ‘VacSYn’ Parkinson’s disease (PD) trial to complete Cohort 1 enrollment and report initial safety findings by year-end
• Cash position of CHF 79.9 million finances the Company into Q4 2024, excluding the benefit of anticipated milestone payments

Lausanne, Switzerland, November 3, 2023 – AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision medicine for neurodegenerative diseases, today reported results for the third quarter ended September 30, 2023, and provided a corporate update.

Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “As we look to year-end and into 2024, AC Immune is poised to achieve multiple milestones across our clinical programs. We remain on track to report safety and immunogenicity data from the AD cohort of our ABATE trial of ACI-24.060 this year. Then, in the first half of 2024 results are anticipated from the important Abeta-PET imaging analyses on amyloid plaque reduction following 6 months of treatment. With amyloid clearance as measured by PET imaging now established as a reliable surrogate for efficacy, these results could significantly de-risk the program and enable advancement into a registrational study. We look forward to further discussing the clinical utility of PET imaging in AD at our KOL webinar on November 9, 2023.”

“We continue to progress our pipeline, and are looking forward to the initiation of the next AD trial of anti-pTau (phosphorylated Tau) active immunotherapy ACI-35.030 later this year, which will be followed by a milestone payment. Taken together with ACI-24.060 and our a-syn active immunotherapy, ACI-7104.056, we will have three active immunotherapies in mid- to late-stage clinical testing for neurodegeneration. With further clinical readouts from our precision medicine pipeline ahead, we continue to work diligently towards earlier diagnosis and treatment to prevent progression of neurodegenerative diseases.”

Q3 2023 and Subsequent Highlights

• A peer-reviewed paper featuring the first-in-human trial of AC Immune’s wholly owned experimental alpha-synuclein (a-syn) positron emission tomography (PET) tracer ACI-12589 comparing healthy control subjects to patients with a-synucleinopathies and other neurological diagnoses was published in Nature Communications.
• KOL webinar on PET imaging in AD featuring Victor Villemagne, M.D. (University of Pittsburg) will be held on November 9, 2023 at 10:00 AM ET. To register for the event, please click here.
• The first patient with PD was dosed in the Phase 2 VacSYn clinical trial evaluating ACI-7104.056, AC Immune’s wholly-owned anti-a-syn active immunotherapy.
• Several programs were showcased at the annual Alzheimer’s Association International Conference (AAIC 2023), including presentations on ABATE’s trial design, TDP-43 proteinopathy in neurodegenerative diseases, and ACI-12589, a novel PET tracer targeting a-syn.
• Announced the appointment of new Chief Medical Officer, Dr Nuno Mendonça.
• Initiated a research collaboration with Prof. Michael Heneka, director of the Luxembourg Centre for Systems Biomedicine, University of Luxembourg, to evaluate the therapeutic potential of AC Immune’s SupraAntigen^®- and Morphomer^®-derived inhibitors of the NLRP3-ASC inflammasome pathway in preclinical disease models.

Anticipated Milestones

Analysis of Financial Statements for the Quarter Ended September 30, 2023

• R&D Expenditures: R&D expenses for the three months ended September 30, 2023, were CHF 12.4 million compared to CHF 14.4 million in the comparable period in 2022, due to lower expenses in our preclinical portfolio and reduced clinical expenses.
• G&A Expenditures: For the three months ended September 30, 2023, G&A increased by CHF 0.2 million, which is materially consistent with the comparable period.
• Other Operating Income: The Company recognized CHF 0.3 million in grant income from Michael J. Fox Foundation and Target ALS grants.
• IFRS Loss for the Period: The Company reported a net loss after taxes of CHF 15.1 million for the three months ended September 30, 2023, compared with a net loss of CHF 13.5 million for the comparable period in 2022.
