Why have anti-Aβ clinical trials failed despite the established role of Aβ in AD pathogenesis?

PARTIALLY ADDRESSED

The abstract suggests that Aβ-tau synergy could explain negative results from anti-Aβ trials, contradicting the expectation that targeting the presumed initiating pathology would be therapeutic. This contradiction has major implications for therapeutic strategy design. Gap type: contradiction Source paper: Synergy between amyloid-β and tau in Alzheimer's disease.
