Access earnings results, analyst expectations, report, slides, earnings call, and transcript.
Overview
The earnings call summary presents a mixed outlook. Financial performance and product development updates appear positive, with new studies and strategic pricing strategies. However, management's vague responses in the Q&A raise concerns about transparency, particularly regarding ulixacaltamide's review process and essential tremor database updates. This lack of clarity may offset the positives, leading to a neutral sentiment.
Key Financial Performance
Q4 2025 Operating Expenses $97 million, broken down to $77.5 million for R&D and $19.5 million for G&A. This compares to Q4 2024, where total operating expenses were $71.4 million, broken down to $56.3 million for R&D and $15.1 million for G&A. The increase was driven by increased spending in the Cerebrum and Solidus platforms to progress the portfolio of clinical programs.
Full Year 2025 Operating Expenses $326 million compared to $209 million in 2024. The increase was driven by increased spending in the Cerebrum and Solidus platforms to progress the portfolio of clinical programs.
Cash, Equivalents, and Marketable Securities (End of Q4 2025) $926 million compared to $469 million as of December 31, 2024. The increase of $457 million was primarily due to net proceeds from Praxis October 25 follow-on public offering and net proceeds from the at-the-market sales of common stock offset by cash used in operations.
Pro Forma Cash (January 2026) Approximately $1.5 billion, strengthened through proceeds from a public offering in January 2026, which yielded $621 million. This cash is expected to fund operations into 2028.

Key Q&A
Q:Can you walk us through the pre-commercial activities for ulixacaltamide and relutrigine and their cadence through 2026?
A:The company is making key hires to build out the commercial organization, ensuring sufficient inventory for strong launches, and improving disease awareness for ulixacaltamide. They are also preparing for presentations at the American Academy of Neurology (AAN) meeting to share clinical data and expand understanding among neurologists.
Q:What additional new data can we expect at the AAN meeting?
A:There will be about 15 presentations, including oral presentations on clinical data for the Essential3 program and essential tremor. These presentations will provide detailed insights into the clinical program, including the primary measure mADL11 and other endpoints, aimed at neurologists.
Q:What is the status of alternative titration schedules for ulixacaltamide, and are additional studies being conducted to support this?
A:The company has proposed an alternative titration schedule to the FDA, which involves staying at 20 mg for longer. The FDA has indicated that no pre-approval clinical studies are required for this, as it is not a safety issue but rather a tolerability matter for a subset of patients.
Q:How is capital being allocated between the commercial preparations for ulixacaltamide and relutrigine?
A:More capital is being allocated to ulixacaltamide due to its broader market, including a larger field force, disease awareness campaigns, and inventory build. Relutrigine's efforts are more focused, targeting specific physician groups and laying groundwork for future indication expansion.
Q:How will the POWER3 study help move vormatrigine towards the frontline setting?
A:POWER3 aims to address the broader market of patients with focal onset seizures who are not hyper-refractory. The study is designed to build confidence among physicians for using vormatrigine as a first-line treatment, although it is not required for registration.
Q:What is the review timeline for the NDAs, and will there be priority reviews?
A:The company has requested a priority review for relutrigine but not for ulixacaltamide. The decision for ulixacaltamide was influenced by strategic business considerations, including launch timing and payer dynamics.
Q:Why did the company decide against requesting a priority review for ulixacaltamide?
A:The decision was influenced by strategic business reasons, including the timing of the launch and the impact of the Inflation Reduction Act on Medicare Part D populations. A standard review aligns better with long-term revenue maximization.
Q:Can we expect long-term follow-up data for ulixacaltamide at the AAN meeting?
A:Yes, the company plans to present data that reinforces both short-term and long-term efficacy, focusing on the depth of effect and the proportion of patients benefiting from the treatment.
Q:What is the pricing strategy for ulixacaltamide?
A:The company has previously indicated a list price of around $50,000 and is considering payer dynamics, reauthorization processes, and the Inflation Reduction Act in its pricing strategy.
Q:How many different DEE patients are being enrolled in the EMERALD study, and what are the expectations for efficacy?
A:The study includes a diverse group of patients with developmental epileptic encephalopathies (DEE), focusing on phenotypically defined patients. Preclinical data suggests strong efficacy, and the company expects similar or better results compared to SCN2A and SCN8A indications.
Q:Will relutrigine be used across the entire spectrum of DEEs, including indications with ASOs or targeted therapies?
A:Yes, relutrigine is expected to be used broadly, including in combination with ASOs, as it addresses a fundamental mechanism in seizures. It is seen as a complementary therapy rather than a silver bullet.
Q:Are patients in the RADIANT study withdrawing from background medications while on vormatrigine?
A:Yes, patients are reducing or eliminating background medications while maintaining seizure control, which highlights vormatrigine's efficacy and safety profile.
Q:What are the expectations for the EMBRAVE study for elsunersen?
A:The EMBRAVE study aims to provide controlled data on safety, efficacy, and pharmacokinetics. The FDA has allowed a single-arm design for EMBRAVE3, which is expected to complete this year, potentially leading to another NDA submission.
Q:What are the plans for ulixacaltamide outside the U.S.?
A:The company is currently focused on the U.S. market and ensuring a high-quality launch. While there is unmet need outside the U.S., international efforts are not a priority at this time.
Q:What is the potential for synergies between the launches of ulixacaltamide and relutrigine?
A:While there is overlap in prescriber populations, the company is taking separate go-to-market strategies for each drug to maximize their individual launches. Future launches may leverage these synergies more effectively.
Q:How does the company view the FDA's position on one adequate and well-controlled study for marketing authorization?
A:The company supports the FDA's evolving stance and believes it could benefit future drug development, but it is not relying on this for its current programs.
Q:What is the status of the essential tremor patient database?
A:The database is well-developed and validated, with a detailed understanding of prescriber patterns. More updates will be provided during the company's Commercial Day.
Q:How does vormatrigine fit into the evolving landscape of focal epilepsy treatments?
A:Vormatrigine is positioned as a potential first-line treatment, differentiating itself from potassium channel-focused therapies that target refractory patients.
Q:What is the status of the alternative titration protocol for ulixacaltamide?
A:The alternative protocol involves staying at 20 mg for longer to improve tolerability. The FDA has not required additional pre-approval studies for this adjustment.
Q:Review of Unclear Management Responses
A:Management avoided directly answering questions about the potential for priority review for ulixacaltamide, providing only strategic business reasons without detailed specifics. Additionally, they did not provide clear updates on the essential tremor patient database, deferring this to a future Commercial Day.
