According to the Complaint, Acadia Pharmaceuticals Inc. ("Acadia" or the "Company") is purportedly a biopharmaceutical company focused on the development and commercialization of medicines to address central nervous system disorders. The Company claims its lead drug is NUPLAZID (pimavanserin), which was approved by the FDA on April 29, 2016 for the treatment of hallucinations and delusions associated with PD Psychosis.
