The drug targets “tau” proteins believed to play a role in Alzheimer’s and offers an alternative to treatments aiming to fight amyloid beta peptides in the brain.

The outcome of the Phase 2 trial – in patients with an early stage of Alzheimer’s – means the failure rate for drugs aiming to fight the brain-wasting illness, which afflicts tens of millions of people worldwide, remains at nearly 100%.

“We believe the full data analysis of this first-of-its-kind study will yield information about this promising target that will advance our understanding and inform future
