AC Immune Reports Full Year 2022 Financial Results and Provides Corporate Update

  • Clinical-stage vaccine programs targeting amyloid-beta (Abeta), phosphorylated-Tau (pTau), and alpha-synuclein (a-syn) are all on track to reach important milestones in 2023
  • ACI-24.060 anti-amyloid-beta vaccine for Alzheimer’s disease (AD) showed positive initial safety and immunogenicity in Phase 1b/2 ABATE trial; further interim data expected in H2 2023; first amyloid plaque PET imaging results anticipated in 2024
  • ACI-35.030 anti-pTau vaccine for AD selected for further development by partner; anticipated H2 2023 initiation of next trial in AD to be followed by milestone payment
  • 2022 cash burn of CHF 70.9 million was better than guidance (2022: CHF 75-80 million) resulting in strong end of year financial position of CHF 122.6 million providing runway into Q3 2024, excluding potential milestone payments

Lausanne, Switzerland, March 16, 2023 – AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision medicine for neurodegenerative diseases, today reported results for the year ended December 31, 2022, and provided a corporate update.

Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “Thanks to the strong progress by our experienced team over the past year, we now have highly innovative vaccines targeting neurotoxic species of Abeta, Tau or a-syn in mid- to late-stage development for Alzheimer’s and Parkinson’s disease, respectively. This progress was highlighted by ABATE’s successful interim readout in AD, which is enabling the quick and informed transition to this adaptive trial’s next cohorts. Importantly, ABATE remains on track for additional readouts on ACI-24.060’s safety and immunogenicity this year, and for interim Abeta PET analyses in 2024 that will provide an opportunity for early de-risking and potentially a rapid transition to a pivotal program.”

“Together, our vaccines and the highly specific diagnostics we are developing against targets such as Tau and a-syn form the cornerstone of our strategy to enable precision medicine for neurodegenerative diseases. With this strategy, our long-term goal is to identify and treat the multifactorial pathologies of each patient at their earliest stages, so that we can minimize irreversible neuronal damage and enable disease prevention.”

2022 and Subsequent Highlights

Pipeline Progress

Vaccine Programs

  • Positive initial interim safety and immunogenicity data from the first AD cohort of the Phase 1b/2 ABATE trial of ACI-24.060, AC Immune’s wholly-owned anti-amyloid beta (Abeta) SupraAntigen® vaccine candidate. Based on these data, ABATE has been expanded, as planned, to begin screening of individuals with Down syndrome (DS) for participation in part 2 of the trial and also to evaluate higher doses in patients with AD. Interim safety and immunogenicity data from AD and DS cohorts are expected in the second half of 2023.
  • ACI-35.030, a potential first-in-class anti-pTau vaccine candidate, was selected for further development, based on clinical data from a Phase 1b/2 trial in AD presented at CTAD 2022. These data showed that vaccination with ACI-35.030 was well tolerated and elicited a strong, durable, and boost-able antibody response against pathological forms of Tau such as pTau and its aggregated form, enriched paired helical filaments. ACI-35.030, generated using AC Immune’s SupraAntigen® technology platform, is being developed in collaboration with Janssen Pharmaceuticals, Inc. (Janssen), part of the Janssen Pharmaceutical Companies of Johnson & Johnson.
  • ACI-24.060 preclinical data published in the peer-reviewed journal Brain Communications, showed it was well tolerated and generated a broad polyclonal immune response with high titers of antibodies against neurotoxic pyroglutamate Abeta (pyroGlu-Abeta), a major component of Abeta plaques. Additional preclinical data demonstrated ACI-24.060’s strong immunogenicity against another key neurotoxic Abeta species, oligomeric Abeta.
  • peer-reviewed publication in JAMA Neurology showed that the first generation formulation of ACI-24.060 was safe and elicited an immune response in the first-ever clinical study of an anti-Abeta vaccine in individuals with DS. Data from the Phase 1b study also provided evidence of target engagement by the polyclonal response to the studied vaccine.

Antibody Programs

  • Detailed results from the Phase 2 Alzheimer’s Prevention Initiative (API) study evaluating the anti-Abeta monoclonal antibody crenezumab in autosomal dominant Alzheimer’s disease (ADAD) were presented at the 2022 Alzheimer’s Association International Conference (AAIC) by AC Immune’s partner Genentech, a member of the Roche group, and the Banner Alzheimer’s Institute. Numerical differences favoring crenezumab were observed across both co-primary endpoints, as well as multiple secondary and exploratory endpoints, though none were statistically significant. All participants in the study were offered up to one year of continued treatment (crenezumab for all carriers and placebo for all non-carrier) following the end of the double-blind period while primary results and additional analyses were pending. Final efficacy visits have begun.
  • Further biofluid biomarker data from the Phase 2 Lauriet trial of the anti-Tau antibody semorinemab in mild-to-moderate AD were presented in a poster at CTAD 2022. Results featured in the poster showed statistically significant post-treatment reductions in pTau and total Tau in the cerebrospinal fluid with semorinemab versus placebo, supporting target engagement and modulation in the central nervous system. The Lauriet open label extension study is ongoing.

Diagnostic Programs

  • The first live images of a-syn in human brains were shown using ACI-12589, an a-syn PET tracer discovered using AC Immune’s Morphomer® platform. Analyses from a clinical study of the tracer presented at AD/PD™ 2022 showed enhanced contrast and a-syn target specificity in patients with multiple system atrophy (MSA), as well as increased tracer retention in brain areas affected by MSA disease processes, highlighting ACI-12589’s potential as the first non-invasive diagnostic for alpha-synucleinopathies (e.g. MSA).
  • AC Immune’s partner, Life Molecular Imaging, imaged the first patient in the pivotal Phase 3 ADvance trial evaluating the Tau PET tracer, PI-2620, in AD. PI-2620 was discovered and developed using the Morphomer® platform as part of a research collaboration between AC Immune and LMI.

Management Team

Thought Leadership and Collaborations

  • Received a follow-on grant from The Michael J. Fox Foundation for Parkinson’s Research (MJFF) to support enhanced clinical studies of ACI-12589.
  • Received new grants from MJFF and the Target ALS Foundation that collectively provide more than USD 500,000 in additional non-dilutive capital to support the advancement of diagnostic programs targeting TDP-43 (TAR DNA-binding protein 43).
  • AC Immune Co-Founder and CEO Dr. Andrea Pfeifer received the prestigious Aenne Burda Award for Creative Leadership in recognition of her work in the field of neurodegenerative diseases.

Analysis of Financial Statements for the Year Ended December 31, 2022

  • Cash Position: The Company had a total cash balance of CHF 122.6 million, composed of CHF 31.6 million in cash and cash equivalents and CHF 91.0 million in short-term financial assets. This compares to a total cash balance of CHF 198.2 million as of December 31, 2021. The Company’s cash balance provides sufficient capital resources to progress into at least Q3 2024 without consideration of potential income milestone payments.
  • Contract Revenues: The Company recorded CHF 3.9 million in contract revenues for the year end December 31, 2022 compared with no contract revenues in the prior year. The increase relates to the progression of PI-2620 into Phase 3 development in AD.
  • R&D Expenditures: R&D expenses decreased by CHF 1.9 million for the year ended December 31, 2022 to CHF 60.3 million, predominantly due to:
    • Discovery and preclinical expenses (- CHF 3.1 million): The Company decreased expenditures across a variety of its discovery and preclinical programs. This decrease was predominantly due to the advancement of the Company’s ACI-24.060 vaccine into clinical studies.
    • Clinical expenses (- CHF 1.8 million): The Company had a net decrease in clinical expenditures largely due to the timing of activities across various cohorts and the completion of certain R&D cost sharing activities for our ACI-35.030 vaccine. We increased expenditures in other clinical programs, notably for the clinical development of ACI-7104.056 and the initiation of our Phase 1b/2a ABATE study for ACI-24.060.
    • Salary- and benefit-related costs (+ CHF 1.2 million): Personnel expenses increased due to the net increase in FTEs in 2022 along with the annualization of 2021 hires.
  • G&A Expenditures: G&A expenses decreased by CHF 2.1 million for the year ended December 31, 2022 to CHF 15.8 million. This decrease is related to prior year transaction costs incurred to complete the asset acquisition of Affiris’ a-syn portfolio and the reduction in personnel expenses.
  • Other Operating Income: The Company recorded CHF 1.3 million in grant income for R&D activities performed under our grants for the year ended December 31, 2022, an increase of CHF 0.1 million compared to the prior period.
  • IFRS Loss for the Period: The Company reported a net loss after taxes of CHF 70.8 million for the year ended December 31, 2022, compared with a net loss of CHF 73.0 million for the prior period.

2023 Financial Guidance

  • AC Immune anticipates that its total cash burn will be in the range of CHF 65 to CHF 75 million for the full year 2023. The Company defines cash burn as operating expenditures adjusted to include capital expenditures and offset by significant non-cash items (including share-based compensation and depreciation expense).
