Current report

A Phase 2 trial to evaluate the efficacy and safety of pimavanserin for the treatment of irritability associated with autism spectrum disorder in pediatric populations was completed in October 2024. The trial did not meet either of its primary or secondary endpoints. With the completion of the trial, we believe we now have completed the FDA’s requirements to qualify for a pediatric exclusivity for pimavanserin. If the period exclusivity is granted, exclusivity of the NUPLAZID franchise would be extended by six months.

Current report

Research and development expenses decreased to $66.6 million for the three months ended September 30, 2024, including $3.9 million in stock-based compensation expense, from $157.0 million for the three months ended September 30, 2023, including $5.1 million in stock-based compensation expense. The decrease in research and development expenses was mainly due to decreased business development payments, which in the period ending September 30, 2023 included the $100.0 million payment to Neuren under the expanded license agreement for trofinetide.

Current report

Comparison of the Nine Months Ended September 30, 2024 and 2023

Current report

Research and development expenses decreased to $202.5 million for the nine months ended September 30, 2024, including $11.7 million in stock-based compensation expense, from $284.9 million for the nine months ended September 30, 2023, including $12.7 million in stock-based compensation expense. The decrease in research and development expenses was mainly due to decreased business development payments, which in the period ending September 30, 2023 included the $100.0 million payment to Neuren under the expanded license agreement for trofinetide, partially offset by increased costs from clinical stage programs.

Previous report

Research and development expenses increased to $76.2 million for the three months ended June 30, 2024, including $3.7 million in stock-based compensation expense, from $58.8 million for the three months ended June 30, 2023, including $3.7 million in stock-based compensation expense. The increase in research and development expenses was mainly due to increased costs from ACP101, ACP-204 and early-stage programs, partially offset by a reduction in costs associated with our pimavanserin negative symptoms of schizophrenia program.

Previous report

Research and development expenses increased to $135.9 million for the six months ended June 30, 2024, including $7.8 million in stock-based compensation expense, from $127.9 million for the six months ended June 30, 2023, including $7.6 million in stock-based compensation expense. The increase in research and development expenses was mainly due to increased costs from ACP-101, ACP-204 and early stage programs, partially offset by the elimination of pre-FDA approval trofinetide commercial supply expenses that were included in the previous year as well as a reduction costs associated with our pimavanserin negative symptoms of schizophrenia program.

Previous wording

Looking beyond the U.S., we are advancing efforts to make trofinetide available in additional markets. Our pediatric investigation plan (PIP) has been agreed to with the pediatric committee of the European Medicines Agency (EMA), paving the way for an anticipated filing in the first quarter of 2025. In Japan, we held our first formal meeting with the Pharmaceuticals and Medical Devices Agency (PMDA) in the second quarter of 2024 to discuss our proposed clinical plan. And in Canada, we announced in April 2024 that our New Drug Submission was accepted for filing and granted priority review by Health Canada, potentially leading to an approval in that market around the end of this year.

And in Canada, we announced in October 2024 that Health Canada granted marketing authorization of DAYBUE (trofinetide) for the treatment of Rett syndrome in adult and pediatric patients two years of age and older, making DAYBUE (trofinetide) the first and only drug approved in Canada for the treatment of Rett syndrome.

Previous wording

We have incurred substantial operating losses since our inception due in large part to expenditures for our research and development activities. As of June 30, 2024, we had an accumulated deficit of $2.4 billion. Contingent on the level of business development activities we may complete as well as pipeline programs we may advance, we may continue to incur operating losses for the next few years as we incur significant research and development costs and costs for continued commercialization of NUPLAZID and DAYBUE.

Current wording

We have incurred substantial operating losses since our inception due in large part to expenditures for our research and development activities. As of September 30, 2024, we had an accumulated deficit of $2.3 billion. Contingent on the level of business development activities we may complete as well as pipeline programs we may advance, we may continue to incur operating losses for the next few years as we incur significant research and development costs and costs for continued commercialization of NUPLAZID and DAYBUE.

Previous wording

Cost of sales for a newly launched product does not include the full cost of manufacturing until the initial pre-launch inventory is depleted, and additional inventory is manufactured and sold. Thus, the cost of sales as a percentage of net sales of DAYBUE for the three and six months ended June 30, 2024 was affected by use of the initial pre-launch inventory, which was previously expensed as research and development expense, and is referred to as zero cost inventories. However, we do not expect that the cost of sales as a percentage of net sales of DAYBUE will increase significantly once we commence the sales of full cost inventories.

Previous wording

Our research and development expenses have consisted primarily of fees paid to external service providers, salaries and related personnel expenses, facilities and equipment expenses, and other costs incurred related to pre-commercial product candidates. We charge all research and development expenses to operations as incurred. Our research and development activities have focused on pimavanserin, trofinetide, ACP-101, ACP-204 and other early-stage programs. In connection with the FDA approval of DAYBUE, we are required to conduct post-marketing work, including a clinical study of renal impairment in healthy volunteers, nonclinical carcinogenicity studies, and nonclinical in vitro and clinical in vivo drug interaction studies. We have completed two of the five studies and we are awaiting FDA’s acknowledgement and acceptance of those completed studies. We will be responsible for all costs incurred for these post-marketing requirements. In addition, we expect to incur increased research and development expenses as a result of advancement of our early-stage development pipeline programs.

FDA has released us from one of the five post-marketing requirements (PMRs). In addition, we have fulfilled one of the five PMRs. Of the remaining three PMRs, we have also completed one and we are awaiting FDA’s acknowledgement and acceptance of that completed PMR. We will be responsible for all costs incurred for these PMRs. In addition, we expect to incur increased research and development expenses as a result of advancement of our early-stage development pipeline programs.

Previous wording

We expect our research and development expenses will continue to be substantial as we conduct studies pursuant to our post-marketing requirements and pursue the further development of ACP-101, ACP-204 and other early-stage pipeline programs. The lengthy process of completing clinical trials and supporting development activities and seeking regulatory approval for our product candidates requires the expenditure of substantial resources. Any failure by us or delay in completing clinical trials, or in obtaining regulatory approvals, could cause our research and development expenses to increase and, in turn, have a material adverse effect on our results of operations.

Previous wording

Our results of operations have fluctuated significantly from period to period in the past and are likely to continue to do so in the future. We anticipate that our quarterly and annual results of operations will be impacted for the foreseeable future by several factors, including the progress and timing of expenditures related to our commercial activities associated with NUPLAZID and DAYBUE and the extent to which we generate revenue from product sales, our further development of our early-stage pipeline programs and the progress and timing of expenditures related to studies of DAYBUE pursuant to our post-marketing requirements. Further, we expect our sales allowances to vary from quarter to quarter due to fluctuations in our Medicare Part D Coverage Gap liability and the volume of purchases eligible for government mandated discounts and rebates, as well as changes in discount percentages that may be impacted by potential future price increases and other factors. We cannot predict with certainty what the full impact that geopolitical and macroeconomic developments may have on our business, results of operations, financial condition and prospects. Due to these fluctuations, we believe that the period-to-period comparisons of our operating results are not a good indication of our future performance.

Current wording

Net product sales, comprised of NUPLAZID and DAYBUE, were $250.4 million and $211.7 million for the three months ended September 30, 2024 and 2023, respectively.

Previous wording

Net product sales of NUPLAZID were $287.3 million and $260.5 million for the six months ended June 30, 2024 and 2023, respectively. The increase in net product sales of NUPLAZID of $26.8 million was due to the growth in NUPLAZID unit sales as well as a higher average net selling price of NUPLAZID in 2024 compared to 2023. Net product sales of DAYBUE were $160.5 million and $23.2 million for the six months ended June 30, 2024 and 2023, respectively. The increase in net product sales of DAYBUE of $137.3 million was due to the growth in DAYBUE unit sales.

Current wording

Net product sales of NUPLAZID were $159.2 million and $144.8 million for the three months ended September 30, 2024 and 2023, respectively. The increase in net product sales of NUPLAZID of $14.4 million was due to the growth in NUPLAZID unit sales as well as a higher average net selling price of NUPLAZID in 2024 compared to 2023. Net product sales of DAYBUE were $91.2 million and $66.9 million for the three months ended September 30, 2024 and 2023, respectively. The increase in net product sales of DAYBUE of $24.3 million was due to the growth in DAYBUE unit sales as well as a higher average net selling price of DAYBUE.

Previous wording

Cost of product sales was $18.2 million and $7.5 million for the three months ended June 30, 2024 and 2023, respectively, or approximately 8% and 5% of net product sales, respectively. Cost of product sales as a percentage of net product sales for NUPLAZID remained relatively flat during the three months ended June 30, 2024 as compared to the same period of 2023. The increase in cost of product sales was primarily due to the increase in license fees and royalties expensed for DAYBUE, including royalties due to Neuren based on net sales of DAYBUE and the amortization of the milestone payments capitalized under our 2018 license agreement with Neuren. The license fees and royalties expensed during the three months ended June 30, 2024 were $10.8 million as compared to $3.7 million in the same period of 2023. We are required to pay Neuren tiered and escalating royalties between 10% to 15% based on annual net sales of DAYBUE in North America. Currently, we are required to pay 10% of royalties to Neuren. If our annual net sales of DAYBUE in North America exceed $250.0 million, we will be required to pay 12% of royalties to Neuren on net sales that exceed $250.0 million. We will be required to pay higher royalties if net sales exceeds next scales.

Current wording

Cost of product sales was $18.9 million and $14.6 million for the three months ended September 30, 2024 and 2023, respectively, or approximately 8% and 7% of net product sales, respectively. Cost of product sales as a percentage of net product sales for NUPLAZID remained relatively flat during the three months ended September 30, 2024 as compared to the same period of 2023. The increase in cost of product sales was primarily due to the increase in license fees and royalties expensed for DAYBUE, including royalties due to Neuren based on net sales of DAYBUE and the amortization of the milestone payments capitalized under our 2018 license agreement with Neuren. The license fees and royalties expensed during the three months ended September 30, 2024 were $11.5 million as compared to $8.1 million in the same period of 2023. We are required to pay Neuren tiered and escalating royalties between 10% to 15% based on annual net sales of DAYBUE in North America. Since our aggregate net sales of DAYBUE in North America exceeded $250.0 million in September 2024, we are required to pay 10% of royalties to Neuren on net sales less than or equal to $250.0 million and 12% of royalties on net sales that exceed $250.0 million.

Previous wording

Certain manufacturing related expenses incurred prior to DAYBUE receiving FDA approval were classified as research and development expenses, resulting in zero cost inventory. If cost of product sales included previously expensed inventories, the total cost of sales with these manufacturing costs included for the three months ended June 30, 2024 would have increased by approximately $3.7 million.

The increase in selling, general and administrative expenses was primarily driven upfront costs related to a new consumer activation program to support the NUPLAZID franchise, increased marketing costs in the U.S. to support DAYBUE, and investments to support commercialization of trofinetide outside the U.S.

Current wording

Selling, general and administrative expenses increased to $133.3 million for the three months ended September 30, 2024, including $21.9 million in stock-based compensation expense, from $97.9 million for the three months ended September 30, 2023, including $13.2 million in stock-based compensation expense. The increase in selling, general and administrative expenses was primarily driven by costs related to a consumer activation program to support the NUPLAZID franchise and the transition costs of approximately $14.9 million as a result of the departure of our former CEO and appointment of our new CEO.

Previous wording

Certain manufacturing related expenses incurred prior to DAYBUE receiving FDA approval were classified as research and development expenses, resulting in zero cost inventory. Prior to receiving FDA approval for DAYBUE in March 2023, we manufactured inventory and recorded approximately $29.9 million related to the zero cost inventory as research and development expense. Utilizing the actual direct costs to manufacture DAYBUE prior to receiving FDA approval, had the previously expensed inventory been capitalized and recognized when sold, the total cost of sales with these manufacturing costs included for the six months ended June 30, 2024 would have increased by approximately $7.2 million. We do not expect our cost of product sales for DAYBUE to increase significantly as a percentage of net product sales in future periods as we continue to produce inventory for future sales. We expect to finish selling the zero cost inventories of DAYBUE in 2025.

Previous wording

We have funded our operations primarily with revenues from sales of NUPLAZID and DAYBUE since their approvals, and through sales of our equity securities and interest income. We anticipate that the level of cash used in our operations will fluctuate in future periods depending on the levels of spending required for our ongoing and planned commercial activities for NUPLAZID and DAYBUE, our ongoing and planned development activities for ACP-101 as a treatment for PWS and ACP-204 as a treatment for ADP, studies to be conducted pursuant to our post-marketing requirements, our ongoing and planned development activities for other early-stage pipeline programs and strategic business development to further expand our portfolio. We expect that our cash, cash equivalents, and investment securities will be sufficient to fund our planned operations through and beyond the next 12 months.

We anticipate that the level of cash used in our operations will fluctuate in future periods depending on the levels of spending required for our ongoing and planned commercial activities for NUPLAZID and DAYBUE, our ongoing and planned development activities for ACP-101 as a treatment for PWS and ACP-204 as a treatment for ADP, studies to be conducted pursuant to our PMRs, our ongoing and planned development activities for other early-stage pipeline programs and strategic business development to further expand our portfolio. We expect that our cash, cash equivalents, and investment securities will be sufficient to fund our planned operations through and beyond the next 12 months.
