• Research and development expenses for full year 2025 increased by $114.7 million to $267.1 million, primarily due to increased activity in the Cerebrum and Solidus platforms and personnel-related costs.
• General and administrative expenses for full year 2025 increased by $2.8 million to $59.1 million, mainly attributable to professional fees.
• Diluted net loss per share increased to $(3.50) for Q4 2025 from $(2.94) for Q4 2024, and to $(13.48) for full year 2025 from $(10.21) for full year 2024.

Risks

• Uncertainties inherent in clinical trials, including their design, conduct, and outcomes.
• Risks concerning the expected timing of clinical trials, data readouts, and the results thereof.
• Uncertainties regarding the timing and success of submissions for regulatory approval or review by governmental authorities.
• Risks related to obtaining necessary regulatory approvals to conduct trials.
• Other risks concerning Praxis programs and operations as described in its Annual Report on Form 10-K for the year ended December 31, 2025 (to be filed) and other filings made with the Securities and Exchange Commission.

Future Outlook

Praxis anticipates transitioning into a commercial company pending positive FDA reviews for ulixacaltamide and relutrigine. The company expects topline results for vormatrigine and elsunersen in the first half of 2026, with additional NDA submissions planned within the next two years. These four assets are projected to have a revenue potential exceeding $20 billion. Commercial preparations for ulixacaltamide and relutrigine will accelerate throughout 2026, and the company's current cash position is expected to fund operations into 2028.

Management Comments

• "After a landmark fourth quarter, filled with a breadth of clinical and regulatory advancements across our portfolio, we started 2026 with two NDA submissions for ulixacaltamide and relutrigine. Pending their expected positive reviews, we will be positioned to transition into a commercial company." Marcio Souza, President and Chief Executive Officer.
• "The other two programs in the clinic, vormatrigine and elsunersen, will both have topline results in the first half of 2026, keeping us on track for additional NDA submissions in the next two years. Together, these four assets have a revenue potential of over $20 billion." Marcio Souza, President and Chief Executive Officer.

Industry Context

StockSavvy.ai notes that Praxis Precision Medicines is making significant strides in the CNS precision neuroscience space, particularly with its dual platform approach (Cerebrum small molecule and Solidus ASO). The submission of two NDAs for ulixacaltamide and relutrigine positions Praxis to potentially enter the commercial stage, a critical transition for biopharmaceutical companies. The focus on rare and undertreated neurological disorders like essential tremor and DEEs, coupled with Breakthrough Therapy Designations, suggests a strong competitive advantage in niche markets with high unmet needs. The projected $20 billion revenue potential for its four late-stage assets, if realized, would place Praxis among the leaders in specialized CNS therapeutics, potentially challenging established players in epilepsy and movement disorders.

Comparison to Industry Standards

• Ulixacaltamide is noted as the first investigational therapy to demonstrate positive results in a Phase 3 program for Essential Tremor (ET), a condition with no specific FDA-approved drugs, positioning it uniquely compared to existing off-label treatments.
• Vormatrigine is described as the 'most potent sodium-channel modulator ever developed for epilepsy' and 'best-in-disease therapy' for focal onset seizures, suggesting a potential superior profile compared to current sodium channel therapies which have significant safety and efficacy limitations.
• Relutrigine's mechanism of precision sodium channel modulation and strong efficacy in SCN2A and SCN8A DEEs, along with Breakthrough Therapy and Orphan Drug Designations, indicates a targeted approach for severe developmental epilepsies, potentially offering better outcomes than broad-spectrum anti-epileptic drugs.
• Elsunersen, an ASO targeting SCN2A gene expression, aims to be the first disease-modifying treatment for SCN2A-DEE, a rare genetic epilepsy, which would be a significant advancement over symptomatic treatments.
• The company's cash runway into 2028, following significant capital raises, provides a longer operational horizon compared to many early-stage biotechs that frequently face near-term funding pressures.

Management Changes

Stakeholder Impact

• Shareholders: Positive impact due to two NDA submissions, strong cash position extending runway, and potential for significant future revenue. Increased net loss and R&D expenses are expected for a company in this stage of development.
• Patients: Highly positive impact with potential new treatments for essential tremor and severe epilepsies (SCN2A/SCN8A DEEs), addressing significant unmet medical needs.
• Employees: Positive impact through company growth, commercial scaling, and key promotions/appointments, indicating job stability and expansion.
• Regulatory Authorities: Continued engagement with FDA through NDA submissions and ongoing clinical trial discussions.

Next Steps

• FDA review of ulixacaltamide and relutrigine NDAs.
• Accelerate commercial preparations and pre-launch activities for ulixacaltamide and relutrigine through 2026.

Key Dates

Recommendation

Praxis Precision Medicines has achieved critical milestones with two NDA submissions for ulixacaltamide and relutrigine, positioning the company for a transition to commercialization. The strong cash position, bolstered by recent offerings, provides a runway into 2028, significantly de-risking near-term operations. Positive clinical data across multiple programs, including Breakthrough Therapy Designations, indicates a robust pipeline addressing high unmet medical needs with substantial market potential. While net losses increased, this is typical for a biotech in late-stage development and is offset by the significant progress towards commercial revenue generation. The strategic management appointments further strengthen the company's leadership for the upcoming commercial phase.
