Alzheimer’s disease is the most prevalent neurodegenerative disease leading to dementia and a major focus of AC Immune. In recent years, as our pipeline has grown, we have diversified to develop product candidates targeting Parkinson’s disease and other NeuroOrphan diseases.

ACI‑35.030 (JNJ-2056)
Alzheimer's disease
The first-in-class anti-pTau active immunotherapy candidate ACI-35.030 was designed to elicit antibodies against extracellular phosphorylated Tau (pTau) to prevent and reduce the spread of Tau pathology. pTau is a key component of Alzheimer’s disease and can be measured in plasma to identify who is at risk of developing Alzheimer’s disease up to 20 years before onset of clinical symptoms.

Abeta
ACI‑24.060
Alzheimer's disease
ACI-24 anti-Abeta active immunotherapy candidates are designed to generate antibodies specifically targeting misfolded Abeta to prevent accumulation and enhance clearance of amyloid plaques. Based on preclinical results, immunization with ACI-24.060 is expected to produce a broad immune response binding key pathological species such as Abeta oligomers and the highly neurotoxic pyroglutamate Abeta (N3pE-Abeta).

a-syn
ACI‑7104.056
Parkinson's disease
ACI-7104.056 is an optimized formulation of its clinically validated anti-a-syn predecessor active immunotherapy. It generates a target-specific antibody response against pathological oligomeric a-syn to inhibit spreading and downstream neurodegeneration in early Parkinson’s disease. It produces a strong and boostable antibody response with evidence of target engagement and a signal of clinical efficacy.

ACI-19764
Neuro-inflammation
We have successfully identified various chemical series of potent small molecule NLRP3 inhibitors. They target the intracellular NLRP3 complex in microglia to inhibit the production of pro-inflammatory factors.

Tau
Morphomer® Tau
Alzheimer's disease
Morphomer® Tau aggregation inhibitors are first-in-class small molecules designed to cross cell membranes and inhibit intracellular Tau aggregates. They also promote disaggregation of already formed aggregates which enhances their therapeutic potential in advanced stages of disease.

Morphomer® a‑syn
Parkinson's disease
We identified and characterized biologically active small molecule aggregation inhibitors targeting intracellular a-syn aggregates. These significantly decrease a-syn accumulation inside neurons and have favorable CNS-penetrant pharmacokinetic properties.

and others
The Tau-PET tracer PI-2620 was designed to specifically bind pathological forms of human Tau in Alzheimer’s disease and other Tauopathies. It crosses the blood brain barrier and has high selectivity, even during early disease stages. A major differentiator is its ability to bind to 4-repeat (4R) Tau isoforms extending its use to diseases driven by these Tau species.
