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

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

  • Received FDA Fast Track Designation for ACI-24.060 anti-amyloid-beta (Abeta) active immunotherapy to treat Alzheimer’s disease (AD)
  • Enrollment in ongoing Phase 1b/2 ABATE study of ACI-24.060 in AD and Down syndrome (DS) is on track and expanding to sites in USA following IND clearance, dosed first individual with DS
  • Next interim safety and immunogenicity data from AD and DS cohorts in ABATE expected in H2 2023
  • Results of amyloid plaque reduction analysis (Abeta-PET) after treatment with ACI-24.060 in ABATE study expected in H1 2024; these results could potentially provide an opportunity to accelerate into a registrational program
  • Cash position of CHF 93.0 million finances the Company into Q3 2024, excluding the benefit of anticipated milestone payments

Lausanne, Switzerland, August 4, 2023 – AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision medicine for neurodegenerative diseases, today reported results for the second quarter ended June 30, 2023, and provided a corporate update.

Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “We entered the second half of 2023 with strong momentum. ACI-24.060’s Fast Track designation acknowledges its potential as a next-generation anti-Abeta active immunotherapy positioned to offer best-in-class efficacy, an improved safety profile, and fewer administration and distribution constraints compared to monoclonal antibodies. With our ABATE trial enrolling AD patients in Europe and expanding the DS cohort via US sites, ACI-24.060 is moving expeditiously towards additional interim safety and immunogenicity data, and Abeta-PET imaging analyses on amyloid plaque reduction in AD in the first half of 2024. Demonstration of Abeta plaque clearance, a validated surrogate marker for clinical efficacy, would provide a major opportunity to rapidly transition to a registrational program.”

“We also look forward to the initiation of the next AD trial of ACI-35.030, the anti-pTau (phosphorylated Tau) active immunotherapy later this year, to be followed by a milestone payment. The progress of our programs affirms our commitment to developing precision medicine approaches to improve outcomes for patients, and ultimately, to prevent progression of neurodegenerative diseases through earlier diagnosis and early intervention.”

Q2 2023 and Subsequent Highlights

  • Received Fast Track designation from the U.S. Food and Drug Administration (FDA) for ACI-24.060, AC Immune’s wholly-owned SupraAntigen®-based anti-Abeta active immunotherapy candidate, for the treatment of AD.
  • Ongoing Phase 1b/2 ABATE study of ACI-24.060 in patients with AD and individuals with DS is on track and expanding to sites in the USA following FDA Investigational New Drug (IND) clearance.
  • The first participant with DS was dosed in the Phase 1b/2 ABATE trial.
  • The first patient with Parkinson’s disease was dosed in the Phase 2 VacSYn clinical trial evaluating ACI-7104.056, AC Immune’s wholly-owned anti-alpha-synuclein (a-syn) active immunotherapy.
  • Several programs were showcased at the annual Alzheimer’s Association International Conference (AAIC 2023), which included a poster detailing ABATE’s trial design, a “Perspectives Session” focused on TDP-43 proteinopathy in neurodegenerative diseases organized by AC Immune scientists, and an oral presentation showing detailed data on ACI-12589, a novel positron emission tomography (PET) tracer targeting a-syn.
  • The TDP-43-PET tracer program has progressed as planned and a clinical candidate has been selected. Over the coming months further preclinical work will be completed to permit the initiation of a first in human study in 2024.
  • A peer-reviewed paper describing our therapeutic antibody candidate targeting TDP-43 was publishedpublished in the journal ‘mAbs’.
  • Initiated a research collaboration with Prof. Michael Heneka, director of the Luxembourg Centre for Systems Biomedicine, University of Luxembourg, to further evaluate the therapeutic potential of AC Immune’s SupraAntigen®- and Morphomer®-derived inhibitors of the NLRP3-ASC inflammasome pathway in preclinical disease models.
  • Hosted a webinar on early diagnosis and prevention of AD featuring presentations by key opinion leaders Kaj Blennow, MD, PhD, of University of Gothenburg and Sahlgrenska University Hospital, and Giovanni Frisoni, MD, of University of Geneva and the Memory Clinic at Geneva University Hospital.

  • Announced the appointment of new Chief Medical Officer, Nuno Mendonça, MD.
