SAN DIEGO / May 08, 2024 / Business Wire / Acadia Pharmaceuticals Inc. (Nasdaq: ACAD) today announced its financial results for the first quarter ended March 31, 2024.

“In the first quarter of 2024, Acadia delivered net product sales of $205.8 million, representing 74% revenue growth year over year, primarily due to the addition of our second commercial product, DAYBUE for the treatment of Rett syndrome, combined with growth in market share of NUPLAZID for the treatment of Parkinson’s disease psychosis,” said Steve Davis, Chief Executive Officer. “In addition, we are executing on our plans to bring DAYBUE to markets outside the U.S., continuing to enroll our late-stage trials in Prader-Willi syndrome and Alzheimer’s disease psychosis, and utilizing our financial strength to support our early-stage pipeline and business development opportunities.”

Company Updates

Financial Results

Revenues

Total revenues, comprised of net product sales from NUPLAZID and DAYBUE were $205.8 million for the three months ended March 31, 2024.

Net product sales of NUPLAZID were $129.9 million for the first quarter of 2024, an increase of 10% as compared to $118.5 million for the first quarter of 2023. The increase in net product sales of NUPLAZID was due to 6% sell in growth and a 4% net price benefit in 2024 compared to 2023.

Net product sales of DAYBUE were $75.9 million for the first quarter of 2024. There were no net product sales of DAYBUE in the first quarter of 2023.

Research and Development

Research and development expenses for the first quarter of 2024 were $59.7 million, compared to $69.1 million for the same period of 2023. The decrease in research and development expenses was mainly due to trofinetide commercial supply build that was expensed in the first quarter of 2023, prior to FDA approval. Post-approval inventory expenditures are expensed as part of cost of goods sold.

Selling, General and Administrative

Selling, general and administrative expenses for the first quarter of 2024 were $108.0 million, compared to $101.2 million for the same period of 2023. The increase in selling, general and administrative expenses was primarily driven by annualization of DAYBUE expenses as well as foundational investments to commercialize trofinetide outside the U.S.

Net Income (Loss)

For the first quarter of 2024, Acadia reported net income of $16.6 million, or $0.10 per common share, compared to a net loss of $43.0 million, or $0.27 per common share, for the same period in 2023. Net income for the three months ended March 31, 2024 included $14.8 million of non-cash stock-based compensation expense.

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.

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 2 years of age and older by the U.S. Food and Drug Administration in March 2023 under the trade name DAYBUE.
