AC Immune Stock Plunges After anti-Tau Alzheimer’s Drug Trial Fails

Updated: 23 Sep 2020

Switzerland based pharmaceutical company AC Immune (NASDAQ: ACIU) and its partner Roche Group have announced that its antiTau Alzheimer's disease drug, semorinemab did not meet its primary endpoint in Phase 2 trials.

The company said that two secondary endpoints were also not met.

“Today's news is surprising and disappointing, given what we as a field know about Tau and its strong spatiotemporal correlation with both symptoms and pathology in AD,” said Professor Andrea Pfeifer, CEO of AC Immune.


Pfeifer continued, commenting that the company's “proven business model of discovery, early development and partnering high-risk therapeutic candidates for AD have successfully generated CHF 334 million in non-dilutive funding and enabled us to accelerate clinical development of our product candidates in collaboration with world-leading partners.
