- 3Q22 net sales of $130.7 million

- Prescription Drug User Fee Act action date set for March 12, 2023 for trofinetide for the treatment of Rett syndrome

Acadia Pharmaceuticals Inc. (Nasdaq: ACAD), today announced its financial results for the third quarter ended September 30, 2022.

NUPLAZID delivered net sales of $130.7 million in the third quarter of 2022, driven by sequential demand growth of 2% and an acceleration of growth in the long-term care (LTC) channel, offset by a reduction of in-channel inventory of approximately $7 million.

“Our third quarter results reflect continued growth in demand for NUPLAZID, driven by early signs of improvement in the long-term care channel,” said Steve Davis, Chief Executive Officer. “In the quarter we announced that our new drug application of trofinetide for the treatment of Rett syndrome has been accepted for filing by the FDA and granted a priority review. Furthermore, we continued to advance our late and early-stage portfolio, including our Phase 3 program for pimavanserin for the treatment of the negative symptoms of schizophrenia and our Phase 1 ACP-204 program for neuropsychiatric indications.”

Company Updates

• Trofinetide New Drug Application (NDA) for the treatment of Rett syndrome was accepted for filing by the U.S. Food and Drug Administration (FDA).

• Presented clinical data for trofinetide at medical congresses in October, including the positive Phase 3 Lavender results and the Daffodil study in girls aged 2-4 with Rett syndrome, at the 51st Annual Meeting of the Child Neurology Society (CNS) in Cincinnati, OH and the National Organization for Rare Diseases (NORD) & Orphan Products 2022 Summit in Washington, DC.

• Continue to expect enrollment to complete in ADVANCE-2, a Phase 3 study evaluating pimavanserin for the negative symptoms of schizophrenia, around mid-year 2023.

Financial Results

Revenue

Net sales of NUPLAZID^® (pimavanserin) were $130.7 million for the three months ended September 30, 2022, a decrease of 1% as compared to $131.6 million reported for the three months ended September 30, 2021. Net sales for the quarter were driven by sequential demand growth of 2% and an acceleration of growth in the LTC channel, offset by a reduction of in-channel inventory of approximately $7 million. For the nine months ended September 30, 2022, Acadia reported net product sales of $380.7 million, an increase of approximately 8% as compared to $353.4 million reported for the nine months ended September 30, 2021.

Research and Development

Research and development expenses for the three months ended September 30, 2022 were $81.3 million, compared to $58.6 million for the same period of 2021. The increase in research and development expenses during the quarter was primarily due to a $10 million milestone payment accrued to Neuren upon acceptance of the trofinetide NDA filing, as well as increased costs of manufacturing activities for trofinetide and the development of early-stage programs. For the nine months ended September 30, 2022 and 2021, research and development expenses were $285.8 million and $172.5 million. The increase was primarily due to the $60 million upfront payment made to Stoke Therapeutics for a license and collaboration agreement and the previously mentioned $10 million milestone as well as increased costs for trofinetide and early-stage programs.

Selling, General and Administrative

Selling, general and administrative expenses for the three months ended September 30, 2022 were $78.1 million, compared to $81.7 million for the same period of 2021. For the nine months ended September 30, 2022 and 2021, selling, general and administrative expenses were $264.7 million and $290.1 million, respectively. The decrease was primarily due to decreased advertising and promotional costs.

About NUPLAZID^® (pimavanserin)

Pimavanserin is a selective serotonin inverse agonist and antagonist preferentially targeting 5-HT_2A 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 in other neuropsychiatric conditions.

About Trofinetide

Trofinetide is an investigational drug. It is a novel synthetic analog of the amino‐terminal tripeptide of IGF-1 designed to treat the core symptoms of Rett syndrome by potentially reducing neuroinflammation and supporting synaptic function. Trofinetide is thought to stimulate synaptic maturation and overcome the synaptic and neuronal immaturities that are characteristic of Rett syndrome pathophysiology. In the central nervous system, IGF-1 is produced by both of the major types of brain cells – neurons and glia. IGF-1 in the brain is critical for both normal development and for response to injury and disease. Trofinetide has been shown to inhibit the production of inflammatory cytokines, inhibit the overactivation of microglia and astrocytes, and increase the amount of available IGF-1 that can bind to IGF-1 receptors.
