ACADIA Pharmaceuticals Reports Financial Results for the Fourth Quarter and Year Ended December 31, 2014

ACADIA Pharmaceuticals Inc. (NASDAQ: ACAD), a biopharmaceutical company focused on the development and commercialization of innovative medicines that address unmet medical needs in neurological and related central nervous system disorders, today announced its financial results for the fourth quarter and year ended December 31, 2014.

ACADIA reported a net loss of $28.4 million, or $0.28 per common share, for the fourth quarter of 2014, compared to a net loss of $12.0 million, or $0.13 per common share, for the fourth quarter of 2013. The net losses for the fourth quarters of 2014 and 2013 included $4.6 million and $2.2 million, respectively, in non-cash, stock-based compensation expense. For the year ended December 31, 2014, ACADIA reported a net loss of $92.5 million, or $0.95 per common share, compared to a net loss of $37.9 million, or $0.44 per common share, for 2013. The net losses for 2014 and 2013 included $16.0 million and $5.7 million, respectively, in non-cash, stock-based compensation expense.

At December 31, 2014, ACADIA’s cash, cash equivalents, and investment securities totaled $322.5 million compared to $185.8 million at December 31, 2013. This increase was primarily due to net proceeds from sales of equity securities, including $196.8 million raised in a public offering in March 2014, offset in part by cash used to fund ACADIA’s operations.

“Our accomplishments in 2014, highlighted by NUPLAZIDTM receiving Breakthrough Therapy designation from the FDA, our strengthened balance sheet, and our commercial preparations, set the stage for a promising 2015,” said Uli Hacksell, Ph.D., Chief Executive Officer of ACADIA. “Importantly, we continue to advance our Parkinson’s disease psychosis program towards registration and remain on track to submit our New Drug Application to the FDA in the first quarter of 2015.”

“We have an important year ahead of us as we continue to add to our commercial capabilities and prepare for the planned launch of NUPLAZID in the United States. We also plan to initiate studies with pimavanserin where new therapies are greatly needed, including schizophrenia and sleep disturbances in Parkinson’s patients, as well as continuing our ongoing Phase II study with pimavanserin in Alzheimer’s disease psychosis. Additionally, we will prepare a Marketing Authorization Application for NUPLAZID for submission in Europe. In all, 2015 will be a pivotal year for ACADIA as we advance NUPLAZID towards commercialization in the United States and broaden the program into additional neurological and psychiatric indications for which there are large unmet medical needs.”

Research and development expenses increased to $18.2 million for the fourth quarter of 2014, including $1.7 million in stock-based compensation, from $7.9 million for the comparable quarter of 2013, including $791,000 in stock-based compensation. This increase was primarily due to an increase of $7.8 million in external service costs associated with the development of pimavanserin. Increases in costs associated with ACADIA’s expanded research and development organization, including $1.5 million in increased personnel costs and $948,000 in increased stock-based compensation expense, also contributed to the quarter-over-quarter increase.

General and administrative expenses increased to $10.4 million for the fourth quarter of 2014, including $2.9 million in stock-based compensation, from $4.3 million for the comparable quarter of 2013, including $1.4 million in stock-based compensation. This increase was due to a $2.1 million increase in external service costs largely related to ACADIA’s commercial preparations for the planned launch of NUPLAZID. Also contributing to the quarter-over-quarter increase in general and administrative expenses was a $1.7 million increase in personnel expenses largely related to ACADIA’s preparations for the planned launch of NUPLAZID, as well as a $1.5 million increase in stock-based compensation expense.

ACADIA anticipates that the level of cash used in its operations will increase in future periods in order to fund its work related to the New Drug Application (NDA) submission and review and commercial activities for NUPLAZID, and its ongoing and planned development activities for pimavanserin for other indications. ACADIA currently expects that its cash, cash equivalents, and investment securities will be sufficient to fund its planned operations at least into the second half of 2016.
