AC Immune Reports Third Quarter 2024 Financial Results and Provides a Corporate Update

• ACI-7104.056 VacSYn Phase 2 trial in Parkinson's disease (PD) on track to report interim safety and immunogenicity data

• Prescreening rate for Phase 2b Retain trial of JNJ-2056 (ACI-35.030) in Alzheimer's disease (AD) triggered CHF 24.6 million milestone under agreement
• JNJ-2056 received Fast Track designation from the U.S. FDA

• Cash of CHF 157.9 million at the end of September, plus the CHF 24.6 million milestone payment received in October, provides runway into 2027

Lausanne, Switzerland, November 5, 2024 – AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision therapeutics for neurodegenerative diseases, today reported results for the quarter ended September 30, 2024, and provided a corporate update.

Dr. Andrea Pfeifer, CEO of AC Immune SA, commented, "AC Immune has continued to make great strides in our pipeline programs and partnerships throughout the third quarter and recent months. We are particularly excited about the recognition received for ACI-35.030 from both our partner Janssen, in the form of a CHF 24.6 million milestone payment, and the U.S. Food and Drug Administration (FDA), in the form of Fast Track designation for JNJ-2056, and that the first patient has been dosed in the Retain trial. These milestones and the high level of patient and investigator enthusiasm fueling the rapid rate of prescreening for Retain, further highlight ACI-35.030's unique potential to prevent or slow progression in pre-symptomatic Alzheimer's disease. We are eagerly anticipating reporting in the coming weeks the interim safety and immunogenicity data from the Phase 2 VacSYn study of ACI-7104.056 for the treatment of early PD, as we move towards establishing clinical proof of concept with this active immunotherapy. Overall, this quarter has seen important incremental progress towards our overarching goal of shifting the treatment paradigm of neurodegenerative diseases towards precision medicine and disease prevention. We are now looking forward to a number of potentially transformational value inflection points in the future."

Anticipated 2024 Milestones

Q3 2024 and Subsequent Highlights

• The Phase 2 VacSYn clinical trial of ACI-7104.056 in PD is progressing well with over 30 patients randomized in Part 1 of the study. We are on track to report the first interim safety and immunogenicity data from the trial.

• AC Immune achieved the second Retain-related milestone payment (CHF 24.6 million) under its agreement with Janssen Pharmaceuticals, Inc. (Janssen), a Johnson & Johnson company. The payment was triggered by the rapid rate of prescreening in the potentially registrational Phase 2b Retain trial investigating active-immunotherapy candidate ACI-35.030 (JNJ-2056) to treat preclinical (pre-symptomatic) AD. ACI-35.030 has been shown in Phase 1b/2a clinical testing to induce an antibody response targeting pathologic phosphorylated Tau, while sparing normal physiologic forms of Tau.

  • Retain-related milestone payments now total CHF 40 million, including the first milestone payment earned in December 2023.

  • JNJ-2056 received Fast Track designation from the FDA for AD in July 2024.

• AC Immune's partner Life Molecular Imaging (LMI) received Fast Track Designation for the partners' Tau positron emission tomography (PET) diagnostic, [¹⁸F]PI-2620, from the FDA in AD, progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD).

  • PI-2620 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.

• AC Immune's preclinical results were featured in multiple presentations at the Alzheimer's Association International Conference (AAIC) 2024:

  • A new class of neurodegenerative disease-fighting drugs: morADC (Morphomer®-antibody drug conjugates), presented by M. Derouazi, PhD (CSO of ACIU), featured data from the proprietary morADC platform. Results demonstrated the ability of morADCs to penetrate the blood brain barrier in vivo and produce potent catalytic activity in vitro compared to the parental monoclonal antibody or small molecule alone.

  • Active immunotherapy, ACI-24.060, induces anti-Abeta antibodies with binding profiles mirroring clinically validated monoclonal antibodies, presented by E. Fiorini, PhD (ACIU), featured results from non-human primates showing that ACI-24.060 induced antibody responses with preferential oligomeric Abeta binding as compared to monomeric Abeta.

  • Discovery and preclinical development of [¹⁸F]ACI-19626, a first-in-class TDP-43 PET tracer, presented by T. Seredenina, PhD (ACIU), described the selection of [¹⁸F]ACI-19626 as a potential PET tracer for detection and monitoring progression of TDP-43 aggregates.

Analysis of Financial Statements for the Quarter Ended September 30, 2024

• Cash Position: The Company had a total cash balance of CHF 157.9 million (CHF 103.1 million as of December 31, 2023), composed of CHF 32.4 million in cash and cash equivalents and CHF 125.5 million in short-term financial assets. The Company's cash balance plus the second Retain-related milestone payment of CHF 24.6 million, received in October 2024, provides sufficient capital resources into 2027, assuming no other milestones.

• Contract Revenues: The Company recorded CHF 25.5 million in contract revenues for the three months ended September 30, 2024, compared to nil in the comparable prior period. For the three months ended September 30, 2024, our contract revenues of CHF 25.5 million were related to:

  • the recognition of the second Retain-related milestone payment of CHF 24.6 million under the agreement with Janssen. This milestone payment was triggered by the rapid rate of prescreening in the potentially registrational Phase 2b Retain trial investigating active-immunotherapy candidate ACI-35.030 to treat preclinical AD; and

  • the efforts made under the agreement with Takeda.

• R&D Expenditures: R&D expenses for the three months ended September 30, 2024, were CHF 14.5 million compared to CHF 12.4 million in the comparable period in 2023. The increase was due mainly to higher clinical expenses, driven by the expansion of the ABATE study in our ACI-24.060 active immunotherapy.

• G&A Expenditures: For the three months ended September 30, 2024, G&A increased by CHF 0.3 million to CHF 3.8 million, mostly due to an increase in salaries and related costs, primarily due to new hires and higher expenses from equity awards granted in 2024, which have a higher fair value.

• Other Operating Income: The Company recognized less than CHF 0.1 million in grant income from Target ALS grants.

• IFRS Income/Loss for the Period: The Company reported a net income after taxes of CHF 5.5 million for the three months ended September 30, 2024, compared with a net loss of CHF 15.1 million for the comparable period in 2023.
