AC Immune Initiates Ph1b/2a Study of Anti-Phospho-Tau Vaccine in Alzheimer’s Disease
By targeting specific pathological forms of Tau protein, immunization with anti-Tau vaccines has become an important strategy for the treatment of AD and other Tauopathies because it has the potential to prevent and reduce the development and spread of Tau pathology throughout the brain. AC Immune’s two proprietary technology platforms, SupraAntigenTM and MorphomerTM, have generated anti-Tau therapies and diagnostics including four in clinical development.
This Phase 1b/2a trial is a randomized, multicenter, double-blind, placebo-controlled clinical study with a primary objective to assess the safety, tolerability and immunogenicity of different doses of ACI-35.030 in patients with early AD. Secondary objectives will assess additional immunogenicity parameters, while exploratory endpoints will include notable biomarkers of progression of AD as well as clinical assessments.
ACI-35.030 is a potent liposomal anti-pTau active investigational vaccine designed to elicit antibodies against extracellular phosphorylated pathological Tau protein, in order to prevent and reduce the spread and development of Tau pathology within the brain.
It builds on the success of AC Immune’s ACI-35 vaccine, which has demonstrated an early target-specific antibody response against pTau after the first injection in the vast majority of patients in a Phase 1b study in mild-to-moderate AD. In pre-clinical studies, ACI-35.030 has shown that it retains the excellent non-clinical safety profile and the highly specific antibody response against pathological Tau observed in ACI-35, while demonstrating an enhanced and more homogeneous antibody response with a significant, long-lasting boosting effect.
