Financial Results

Revenues

Total revenues, comprised of net product sales from NUPLAZID and DAYBUE, were $231.0 million for the fourth quarter of 2023 and $726.4 million for the full year 2023.

Net product sales of NUPLAZID were $143.9 million for the fourth quarter of 2023, an increase of 5% as compared to $136.5 million for the fourth quarter of 2022. Net product sales of NUPLAZID were $549.2 million for the full year 2023, an increase of 6% as compared to $517.2 million for the full year 2022. The increase in net product sales of NUPLAZID was due to growth in unit sales and a higher average net selling price in 2023 compared to 2022.

Net product sales of DAYBUE were $87.1 million for the fourth quarter of 2023 and $177.2 million for the full year 2023. During 2022, there were no net product sales of DAYBUE, which was launched in April 2023.

Research and Development

Research and development expenses for the fourth quarter of 2023 were $66.7 million, compared to $75.7 million for the same period of 2022. For the full years of 2023 and 2022, research and development expenses were $351.6 million and $361.6 million, respectively. The decrease in research and development expenses during 2023 was mainly due to trofinetide commercial supply build that was expensed prior to approval. There was a similar level of clinical spend and business development investment year over year.

Selling, General and Administrative

Selling, general and administrative expenses for the fourth quarter of 2023 were $111.5 million, compared to $104.4 million for the same period of 2022. For the full years of 2023 and 2022, selling, general and administrative expenses were $406.6 million and $369.1 million, respectively. The increase in selling, general and administrative expenses was primarily due to increased commercial costs associated with the DAYBUE launch, partially offset by reductions in expenses associated with NUPLAZID.

Net Income (Loss)

For the fourth quarter of 2023, Acadia reported net income of $45.8 million, or $0.28 per common share, compared to a net loss of $41.7 million, or $0.26 per common share, for the same period in 2022.

About NUPLAZID^® (pimavanserin)

Pimavanserin is a selective serotonin inverse agonist and antagonist preferentially targeting 5-HT2A receptors. These receptors are thought to play an important role in neuropsychiatric disorders. In vitro, pimavanserin demonstrated no appreciable binding affinity for dopamine (including D2), histamine, muscarinic, or adrenergic receptors. Pimavanserin was approved for the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis by the U.S. Food and Drug Administration in April 2016 under the trade name NUPLAZID. In addition, Acadia is developing pimavanserin as a potential treatment for the negative symptoms of schizophrenia.

About DAYBUE^™ (trofinetide)

Trofinetide is a synthetic version of a naturally occurring molecule known as the tripeptide glycine-proline-glutamate (GPE). The mechanism by which trofinetide exerts therapeutic effects in patients with Rett syndrome is unknown. Trofinetide was approved for the treatment of Rett syndrome in adults and pediatric patients two years of age and older by the U.S. Food and Drug Administration in March 2023 under the trade name DAYBUE.
