Conference Call Scheduled for Today, March 11, at 5:00 p.m. EasternTime
SAN DIEGO—(BUSINESS WIRE)—Mar. 11, 2015—ACADIA Pharmaceuticals Inc. (NASDAQ: ACAD), a biopharmaceutical companyfocused on the development and commercialization of innovative medicinesthat address unmet medical needs in neurological and related centralnervous system disorders, today provided an update on the planned timingof its NUPLAZIDTM (pimavanserin) New Drug Application (NDA)submission.
ACADIA plans to submit its NUPLAZID NDA for the treatment of Parkinson’sdisease psychosis in the second half of 2015. The company had previouslyplanned to submit the NDA in the first quarter of 2015. The decision tomove back the planned submission is based on additional time required tocomplete the preparation of systems to support commercial manufacturingand supply and, in turn, to support the U.S. Food and DrugAdministration’s (FDA) review of NUPLAZID. The change in submissiontiming is not a result of any change to NUPLAZID’s clinical or safetyprofile, nor is it a result of any interaction with or request forinformation from the FDA.
“We have concluded that additional time is needed to complete thereadiness of our commercial manufacturing systems,” said Steve Davis,Interim Chief Executive Officer of ACADIA. “While we are verydisappointed with the change in timing, we believe that this is theprudent course of action to take. We are working expeditiously to ensurethat our systems are robust and ready for FDA review and commerciallaunch. Importantly, we remain confident in the safety and efficacypackage supporting the NDA of NUPLAZID, which received BreakthroughTherapy designation from the FDA last year.”
Separately, ACADIA Pharmaceuticals issued a news release todayannouncing that Uli Hacksell, Ph.D., has retired as its Chief ExecutiveOfficer and resigned from its Board of Directors effective today. SteveDavis, Executive Vice President, Chief Financial Officer and ChiefBusiness Officer of ACADIA, has been appointed as Interim ChiefExecutive Officer.
