Acadia Pharmaceuticals Inc. (NASDAQ:ACAD) today announced that it will present multiple original data presentations spanning its portfolio at the 2026 American Academy of Neurology (AAN) Annual Meeting, taking place April 18–22, 2026 in Chicago, IL.

The Company will present real-world data from a sub-group analysis of the ongoing, Phase 4, prospective, observational, open-label LOTUS study evaluating the benefits and tolerability of DAYBUE® (trofinetide) in adults with Rett syndrome in routine clinical practice. In support of NUPLAZID® (pimavanserin) in Parkinson's disease psychosis (PDP), Acadia will present exploratory analyses evaluating heterogeneity in treatment response trajectories and the impact of baseline sleep disturbances among PDP patients treated with pimavanserin. The Company is also debuting translational and pharmacokinetic research supporting the continued development of ACP-711, an investigational drug, for essential tremor. Collectively, these data reflect Acadia's ongoing commitment to advancing scientific knowledge across a wide range of neurological conditions.
