- 2Q21 net sales of $115.2 million, a 5% increase over 2Q20

- Fiscal year 2021 revenue guidance reduced to $480 to $515 million

- Type A meeting held with FDA regarding DRP; Acadia will continue discussion with FDA in another meeting later this year

Acadia Pharmaceuticals Inc. (Nasdaq: ACAD), today announced its financial results for the second quarter ended June 30, 2021.

“NUPLAZID performed well in the second quarter of 2021, highlighted by our ability to drive growth while still navigating the continued impact from the pandemic,” said Steve Davis, Chief Executive Officer. “We recently completed a Type A meeting with the FDA regarding pimavanserin for dementia-related psychosis and plan to continue our engagement in another meeting with the FDA later this year to further discuss potential paths to approval. Looking ahead, we plan to announce top-line results by the end of the year from our Phase 3 study in Rett syndrome and our proof-of-concept Phase 2 study in postoperative pain.”

Company Updates

• Completed a Type A End of Review meeting regarding the FDA’s complete response letter (CRL) for the sNDA for pimavanserin for the treatment of hallucinations and delusions associated with dementia-related psychosis (DRP). At the meeting, the FDA reiterated their stated position in the CRL, that pimavanserin should be studied by individual subgroups of dementia, and advised that the best path forward is to conduct an additional clinical study in each of the subgroups for which we seek approval. However, the FDA also indicated that they are open to having another meeting to discuss additional analyses from the HARMONY and -019 studies in support of a potential resubmission without an additional clinical study.

• The New England Journal of Medicine published the positive results from the Phase 3 HARMONY study evaluating pimavanserin in patients with dementia-related psychosis in July 2021.

• Results from an open-label extension safety study with pimavanserin supporting sustained response in Parkinson’s disease psychosis patients was published online in the June 2021 issue of Parkinsonism and Related Disorders.

• Completed enrollment of the Phase 3 LAVENDER study evaluating trofinetide for the treatment of Rett syndrome, with top-line results expected in the fourth quarter of 2021.

• Initiated a Phase 2 study of ACP-044 for pain associated with osteoarthritis in the second quarter of 2021.

• Top-line results from the Phase 2 study of ACP-044 for the treatment of postoperative pain following bunionectomy surgery are expected in the fourth quarter of 2021.

Financial Results

Revenue

Net sales of NUPLAZID^® (pimavanserin) were $115.2 million for the three months ended June 30, 2021, an increase of 5% as compared to $110.1 million reported for the three months ended June 30, 2020. For the six months ended June 30, 2021 and 2020, Acadia reported net product sales of $221.8 million and $200.2 million, respectively.

Research and Development

Research and development expenses for the three months ended June 30, 2021 were $56.9 million, compared to $64.3 million for the same period of 2020. The decrease in the three month period ending June 2021 compared to June 2020 was largely due to the cessation of development costs of pimavanserin for major depressive disorder and lower development costs for DRP. For the six months ended June 30, 2021 and 2020, research and development expenses were $113.9 million and $136.9 million. The decrease for the six month period ending June 2021 compared to June 2020 was largely due to lower development costs of pimavanserin and trofinetide, partially offset by increased development costs for ACP-044.

Selling, General and Administrative

Selling, general and administrative expenses for the three months ended June 30, 2021 were $96.8 million, compared to $84.3 million for the same period of 2020. The increase for the three month period ending June 2021 compared to June 2020 was primarily due to increased costs associated with advertising and promotion, corporate support functions and stock-based compensation. For the six months ended June 30, 2021 and 2020, selling, general and administrative expenses were $208.5 million and $186.3 million, respectively. The increase for the six month period ending June 2021 compared to June 2020 was primarily due to increased costs associated with advertising, promotion and preparations for the potential DRP launch.

2021 Financial Guidance

• NUPLAZID net sales guidance is decreased to $480 to $515 million from the previous range of $510 to $550 million as a result of the continued impact of the pandemic with fewer Parkinson’s disease patient office visits and lower occupancy rates at long-term care facilities, as well as a revised gross-to-net expectation of approximately 20% compared to prior expectation of high teens.
• GAAP R&D is decreased to $250 to $270 million from the previous range of $280 to $300 million. Current R&D guidance includes approximately $25 million of stock-based compensation expense.
• GAAP SG&A guidance is reiterated at $385 to $415 million. Current SG&A guidance includes approximately $50 million of stock-based compensation expense.

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. NUPLAZID is not approved for dementia-related psychosis. 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. 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 granted Fast Track Status and Orphan Drug Designation in the U.S. and Orphan Drug Designation in Europe for both Rett syndrome and Fragile X syndrome.
