Background

This is an anti-tau antibody that grew out of a research collaboration between AC Immune and Genentech, part of the Roche Group. No preclinical data has been published specifically on an investigational therapeutic by this name; however, the AC Immune/Genentech collaboration has focused on approaches that target extracellular, not intracellular, tau. The aim was to explore antibodies with reduced effector function in an effort to limit microglial activation leading to inflammatory responses (e.g., Lee et al., 2016).

Findings

In July 2016, Genentech/Roche Group began enrolling for a first Phase 1 study of 71 volunteers comprising both healthy controls and people with mild to moderate Alzheimer's disease. Conducted in Tennessee, this trial compares the antibody to placebo on safety, tolerability, pharmacokinetics, and preliminary activity outcomes. The trial design combines single dose, dose-escalation, and multiple dosing. The study is expected to run until May 2017.
