  • Reported potent interim immunogenicity results for anti-pTau Alzheimer’s vaccine in ongoing Phase 1b/2a study, which support further development into Phase 2/3

  • Initiated first-in-human clinical study for next-generation alpha-synuclein PET diagnostic with results expected in Q3 2021

  • Advanced multiple candidates targeting the NLRP3 inflammasome pathway for CNS and non-CNS indications

  • Strong financial position of CHF 216.1 million in cash ensures the Company is fully financed through at least Q1 2024

LAUSANNE, Switzerland, April 28, 2021 (GLOBE NEWSWIRE) -- AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision medicine for neurodegenerative diseases, today reported its financial results for the quarter ended March 31, 2021. The Company also provided an overview of its recent clinical and corporate highlights and anticipated milestones for 2021.

Prof. Andrea Pfeifer, CEO of AC Immune SA, commented: “Our clinical and R&D accomplishments over the last quarter serve to strengthen our leadership in precision medicine for neurodegenerative diseases. Encouraging clinical results from both of our Alzheimer’s vaccine programs further reinforce our belief that early intervention, and ultimately prevention, using vaccines represents a key strategy in neurodegenerative diseases. To enable this strategy, we are advancing our suite of novel diagnostics, such as our alpha-synuclein imaging agent, which recently entered the clinic in Parkinson’s disease. Our vision is to address the heterogeneity of neurodegenerative diseases by pairing earlier, more accurate diagnosis with highly selective treatments that address the right proteinopathy, in the right patient, at the right time.”

Prof. Pfeifer continued: “We are poised to achieve four additional clinical readouts in 2021, as we continue progressing our first-in-class preclinical programs addressing alpha-synuclein, TDP-43, and NLRP3-ASC towards the clinic, driving significant future value creation.

Q1 2021 Highlights

Clinical and R&D

  • Reported encouraging top line results from a first-of-its-kind Phase 1b study of anti-Abeta vaccine candidate ACI-24 in people with Down syndrome (DS). These results support further development in Down syndrome-related Alzheimer’s disease (AD). AC Immune also reported promising preclinical results for an optimized anti-Abeta vaccine formulation, for which it expects to file an investigational new drug application (IND) in Q4 2021.

  • Reported promising interim Phase 1b/2a results for ACI-35.030, a novel anti-phospho-Tau (pTau) vaccine candidate, showing strong safety and high titers of antigen-specific antibodies in 100% of older patients with early Alzheimer’s disease. The study is currently enrolling patients into the highest dose group, with further clinical readouts expected this year.

  • Advanced next-generation alpha-synuclein positron emission tomography (PET) tracer candidate, ACI-12589, into a first-in-human clinical study, with an expected data readout in Q3 2021

  • Identified and characterized the first biologically active small molecule Morphomer™ alpha-synuclein aggregation inhibitors, which significantly decreased alpha-synuclein aggregate formation in cellular assays by interfering with the fibrillation process

  • Reported key advancements for several therapeutic programs targeting the (NOD)-like receptor protein 3 (NLRP3) inflammasome, including small molecule inhibitors, which showed the first evidence of in vivo activity in a model of peripheral inflammation, as well as high-affinity monoclonal antibodies that bind extracellular components of the NLRP3 pathway and inhibit inflammasome-mediated immune response in vitro

Thought leadership

  • Co-sponsored a virtual Global Down Syndrome Forum that brought together thought leaders on Down syndrome and Down syndrome-related Alzheimer’s disease to discuss the unmet need and underlying causes of this important health challenge, as well as the broader implications for clinical development in other Alzheimer’s disease populations.

  • Hosted a comprehensive webinar focusing on the Company’s proprietary Morphomer™ platform underlying the generation of therapeutic and diagnostic small molecules, which featured presentations and a Q&A session with members of AC Immune’s Management and R&D Teams.

Strengthening of Board

  • Welcomed Dr. Alan Colowick, an experienced biotech and investment executive, to the Company’s Board of Directors

Achieved and Anticipated 2021 milestones

Analysis of Financial Statements for the quarter ended March 31, 2021

  • Cash Position: The Company had a total cash balance of CHF 216.1 million, composed of CHF 151.1 million in cash and cash equivalents and CHF 65 million in short-term financial assets. This compares to a total cash balance of CHF 225.9 million as of December 31, 2020. The Company’s cash balance provides enough capital resources to progress through at least Q1 2024 without potential incoming milestone payments.

  • Contract Revenues: The Company did not record contract revenues for the three months ended March 31, 2021, a decrease of CHF 12.3 million from the comparable period. The decrease is predominantly related to a CHF 10 million milestone payment as well as CHF 2.1 million in R&D activities recognized in 2020, which did not repeat.

  • R&D Expenditures: R&D expenses decreased by CHF 1.9 million for the three months ended March 31, 2021 to CHF 13.3 million.

    • Discovery and preclinical expenses (+1.2 million): The Company increased expenditures across a variety of its discovery and preclinical programs. These include investments to advance the optimized formulation of our ACI-24 vaccine, the expansion of our Morphomer™ Tau program into NeuroOrphan indications and various other investments across our programs.

    • Clinical expenses (-4.1 million): The Company decreased expenditures across multiple clinical programs, as certain clinical activities completed or incurred significant scaling up in the prior period. For example, the Company completed its clinical activities to complete the Phase 1 trial of our Morphomer™ Tau asset in partnership with Lilly. Additionally, the Company incurred less expense for ACI-24 for DS-related AD as a result of prior period scaling up activities for a Phase 2 clinical trial which were not repeated in the current period.

    • Salary- and benefit-related costs (+1.1 million): The Company’s salary- and benefit-related costs increased primarily due to the internal reallocation of certain employees’ salaries and annualization of 2020 hires and increases in share-based compensation

  • G&A Expenditures: For the three months ended March 31, 2021, G&A decreased by CHF 0.2 million to 4.3 million. This decrease is predominantly related to the internal reallocation of certain employees’ salaries.

  • Other Operating Income: The Company recognized CHF 0.4 million in grant income for R&D activities performed under our MJFF and Target ALS grants, an increase of CHF 0.3 million compared to the prior period

  • IFRS Loss for the Period: The Company reported a net loss after taxes of CHF 16.7 million for the three months ended March 31, 2021, compared with net loss of CHF 7.7 million for the comparable period in 2020

2021 Financial Guidance

For the full year 2021, the Company expects its total cash burn to range between CHF 65 million ‒75 million.
