Reports Q1 revenue $1.12M, consensus $263,230. Andrea Pfeifer, CEO of AC Immune SA, commented: "The progress in our collaborations with Takeda and Eli Lilly reflect great confidence in our anti-Abeta active immunotherapy and Tau aggregation inhibitor small molecules, respectively. These have the potential to change the way we target the proteinopathies that drive Alzheimer's and other neurodegenerative diseases. This is further exemplified by the presentation of the interim results for ACI-7104 at AD/PD 2026 showing that our active immunotherapy targeting a-synuclein (a-syn) has the potential to modify disease pathology in Parkinson's disease. We also advanced our NLRP3 inhibitor ACI-19764 into clinical development, further demonstrating the power of AC Immune's technology to target the key pathways that contribute to neurodegeneration. We are now moving towards multiple value inflection points during 2026. These include Phase 2 data readouts on our active immunotherapies ACI-7104 and ACI-24, and initial results from the Phase 1 trial of ACI-19764 also anticipated this year."

AC Immune Reports Interim Data from ACI-24 Alzheimer's Trial
- Clinical Trial Progress: AC Immune's Phase 1b/2 ABATE trial involving 74 patients with prodromal Alzheimer's disease demonstrated that ACI-24 treatment over 12 months was generally safe and well tolerated, with no evidence of amyloid-related imaging abnormalities (ARIA-E), providing positive safety data for future studies.
- Antibody Response Validation: Anti-Abeta antibody responses were detected at all dose levels in cohorts AD1 to AD3, indicating a dose-response relationship that suggests ACI-24 effectively activates immune responses across different dosages, potentially informing future treatment strategies.
- Adjuvant Testing: The ongoing AD4 cohort aims to enhance ACI-24's immunogenicity by incorporating an additional adjuvant, a strategy that could further improve treatment efficacy and strengthen the company's competitive position in the Alzheimer's treatment market.
- Collaboration with Takeda: AC Immune has secured an exclusive global option and license agreement with Takeda, receiving an upfront payment of $100 million and a milestone payment of $12 million, with potential additional development and sales milestones of up to $2.1 billion, providing substantial financial support for advancing its clinical trials and market entry.
