LAUSANNE, Switzerland, Nov. 13, 2020 (GLOBE NEWSWIRE) -- AC Immune SA ACIU, a Swiss-based, clinical-stage biopharmaceutical company with a broad pipeline focused on neurodegenerative diseases, today announced financial results for Q3 2020 and provided a business update. The Company ended the third quarter with CHF 246.6 million in cash, which ensures operations are fully financed through Q1 2024 allowing the Company to advance our clinical and preclinical projects to key value inflection points while investing further in our diverse pipeline.

Prof. Andrea Pfeifer, CEO of AC Immune SA, commented: "AC Immune continued to advance its world-leading pipeline in Q3 2020, underpinned by our proprietary discovery platforms SupraAntigen^TM and Morphomer^TM and solid financial position.  Our proven business model of early development and partnering of validated therapeutic and diagnostic candidates has made us a global leader in precision medicine for neurodegenerative diseases. All clinical and preclinical milestones  expected this year remain on track with key data across our  Alzheimer's disease (AD) vaccines,  alpha-synuclein and NLRP3-ASC inflammasome programs this year – ­with the latter becoming a focus for neurodegenerative diseases and non-CNS applications. Together these milestones highlight progress in our late stage clinical programs and focus in NeuroOrphan indications with multiple near and mid-term catalysts."

The strength of the Company's diversified approach continues to be demonstrated with the announcement today that the Phase 1 study of the small molecule Morphomer™ Tau aggregation inhibitor, ACI-3024 in healthy young, elderly and Japanese volunteers, has been completed.  In the study, which was conducted in partnership with Eli Lilly and Company, single and multiple dosing with the Morphomer^TM Tau ACI-3024 resulted in a dose-dependent exposure and brain penetration by achieving the desired levels of ACI-3024 in the cerebrospinal fluid. The program will be expanded to NeuroOrphan indications and ACI-3024 will be further evaluated for efficacy in models of rare Tauopathies. Continued candidate characterization across the research program has also identified new and highly differentiated candidates with excellent cerebrospinal fluid exposure and selectivity for pathological aggregated Tau. These will be broadly developed in Tau-dependent neurodegenerative diseases.

Prof. Pfeifer commented: "The pharmacokinetic observations from the Phase 1 trial in our Lilly Morphomer™ Tau partnership program show the first evidence of a Morphomer™ Tau entity meeting the target CNS concentration in humans. Compared to other Tau-targeting molecules in development, the key potential differentiating factor is that our Morphomer™ Tau molecules have been shown to act intracellularly to address Tau pathology, potentially saving affected neurons that otherwise might die. Our Morphomer™ Tau program is the most advanced orally available small molecule therapeutic candidate of its kind in development."

Q3 2020 Research & Development Updates and Highlights:

• The next phase of the strategic partnership between AC Immune and WuXi was  unveiled with plans to accelerate advancement of AC Immune's TDP-43 antibody into clinical development. A particular focus is developing the clinical antibody candidate to ensure it has high-affinity for TDP-43 and is capable of preventing the intercellular spread of toxic species. With no disease modifying therapies currently available that target TDP-43 there is significant unmet need and market potential 
• A highly competitive European Union grant was awarded to support the partnership between AC Immune and the EU Joint Programme – Neurodegenerative Disease Research (JPND) ImageTDP-43 consortium to accelerate development of the Company's first-in-class TDP-43 positron emission tomography (PET) tracer. Advancement of the tracer may enable the development of precision medicine approaches for the large and growing proportion of patients with TDP-43-related pathologies, such as patients with LATE and AD
• Top line results from a Phase 2 trial of the anti-Tau antibody in early (prodromal to mild) AD showed that semorinemab did not meet the co-primary efficacy endpoint or two secondary endpoints in the Tauriel study; the primary safety endpoint was met. Additional data presented at the CTAD 2020 Alzheimer Congress by our partner, Genentech, a member of the Roche group, confirm that semorinemab did not slow clinical progression or Tau accumulation relative to placebo with any of the three different  doses tested. Dose-dependent increases were seen in serum pharmacokinetics and there was clear and consistent evidence of plasma target engagement. Preliminary analysis continues to suggest that semorinemab has an acceptable and well-tolerated safety profile. A second Phase 2 (Lauriet) study of semorinemab in patients with moderate AD remains ongoing
• Initiation of investigational new drug (IND)-enabling studies for AC Immune's first-in-class therapeutic antibody targeting TDP-43. The anti-TDP-43 antibody is the first therapeutic candidate shown to mitigate TDP-43 neuropathology in vivo and the Company plans to develop the antibody for the treatment of NeuroOrphan indications.  Effectively slowing or stopping the spread of TDP-43 pathology throughout the brain could provide the first antibody-based TDP-43 targeted therapeutic approach for treating conditions such as LATE, amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with TDP-43 pathology, representing 50 per cent of all FTLD cases.

Update on Covid-19
AC Immune remains in continuous contact with its partners and other important stakeholders, including the Swiss government, trial investigators and contractors, and at this stage the Company is not modifying guidance with respect to the multiple clinical and preclinical data readouts anticipated this year. AC Immune will continue to keep the market apprised of any new developments or information that may impact clinical timelines.

Analysis of Financial Statements for the Three and Nine Months Ended September 30, 2020

• Revenues: Revenues for the three and nine months ended September 30, 2020 totaled CHF 1.1 million and CHF 14.5 million, respectively. This represents a decrease of CHF 32.1 million and CHF 95.1 million over the comparable periods in 2019. The decrease for the three months ended September 30, 2020 relates to the prior recognition of CHF 30 million for the first installment of the first milestone achieved with Lilly and CHF 2.2 million for the initiation of a Phase 2 trial of Tau PET tracer with Life Molecular Imaging that did not repeat in the current quarter. The decrease for the nine months ended September 30, 2020 predominantly relates to CHF 104.5 million recognized in the prior period associated with our license agreement with Lilly offset by a recognition of a CHF 10 million milestone payment and CHF 4.1 million for research and development activities performed in the current period
• R&D Expenditures: For the three and nine months ended September 30, 2020, R&D expenses increased by CHF 4.0 million (+35.2%) and CHF 7.8 million (+21.7%) to CHF 15.5 million and CHF 43.5 million, respectively. For R&D expenses directly allocated to R&D programs, the Company increased investments in its non-AD programs predominantly led by increases in ACI-24 in Down syndrome related to scaling up activities for a Phase 2 clinical study, investments to advance our alpha-synuclein projects and the development of our anti-TDP-43 antibody with the initiation of IND-enabling studies. For AD, the Company's expenditures for ACI-24 in AD decreased due to completing the manufacturing process development. The Company also spent less for ACI-35 in the current period related to toxicology and manufacturing costs for clinical trial material in the prior period that did not repeat in the current period
  Additionally, personnel costs in R&D increased by CHF 0.6 million and CHF 2.0 million for the three and nine months ended September 30, 2020, respectively driven by an increase of 11 FTEs during the year. The remaining increases of CHF 0.9 million and CHF 1.8 million relate to an increase in regulatory and quality assurance, intellectual property and other unallocated research and development costs
• G&A Expenses: For the three and nine months ended September 30, 2020, G&A expenses increased CHF 0.9 million (+23.7%) and CHF 2.7 million (+25.1%) to CHF 4.9 million and CHF 13.6 million, respectively. Increases were driven by an addition of 4 FTEs as well as an increase in professional services and depreciation expenses.
• IFRS (Loss)/Income for the period: The Company incurred a net loss after taxes of CHF 19.0 million and CHF 42.4 million for the three and nine months ended September 30, 2020, respectively, compared with net income of CHF 18.2 million and CHF 64.9 million for the comparable periods in 2019, predominantly related to the variance in revenues and operating expenses discussed above
• Cash Position: The Company had a total cash balance of CHF 246.6 million, comprised of CHF 176.6 million in cash and cash equivalents and CHF 70 million in short-term financial assets. This compares to a total cash balance of CHF 288.6 million as of December 31, 2019. This decrease of CHF 42 million is principally due to the factors noted above in the income statement which resulted in a CHF 42.4 million net loss for the period and changes in our working capital.
