• PRAX-562 (elizefiban): An investigational therapy in development for rare forms of epilepsy, including SCN2A-DEE and SCN8A-DEE.
• PRAX-944 (ulixacaltamide): An investigational therapy targeting essential tremor, aiming to restore neuronal balance in the brain.

Praxis Precision Medicines (symbol: PRAX) is a clinical-stage biopharmaceutical company. This means that its drug candidates are currently in various stages of clinical trials and have not yet received regulatory approval (e.g., from the FDA in the U.S.) for commercial sale.

As a result, Praxis Precision Medicines does not currently have major commercial customers in the traditional sense of selling approved pharmaceutical products to wholesalers, pharmacies, or healthcare providers. The company's primary activities at this stage are focused on research, development, and conducting clinical trials to advance its potential therapies toward market approval.

Therefore, there are no specific customer companies or categories of individual customers to list at this time.

Sage Therapeutics' SAGE-324 for essential tremor is an emerging competitive threat to Praxis Precision Medicines' PRAX-032. SAGE-324, a GABA-A positive allosteric modulator, has reported positive Phase 2 results and is currently in Phase 2/3 development for essential tremor. Praxis's PRAX-032, a T-type calcium channel blocker, is currently in Phase 1 development for the same indication, with Phase 2 trials planned. If SAGE-324 continues to demonstrate strong efficacy and safety and gains regulatory approval significantly ahead of PRAX-032, or proves to have a superior profile, it could establish a dominant market position, severely impacting PRAX-032's commercial potential and competitive viability.

Praxis Precision Medicines (PRAX) is developing several product candidates with the following estimated addressable market opportunities:

• Ulixacaltamide for Essential Tremor (ET): This condition affects approximately seven million people in the U.S.. Analysts estimate a potential peak sales opportunity of $5 billion for ulixacaltamide globally.
• Vormatrigine for Focal Onset Seizures: This indication could generate approximately $1.8 billion in peak sales globally.
• Relutrigine for SCN2A and SCN8A Developmental and Epileptic Encephalopathies (DEEs): These two DEE indications alone are projected to generate up to $1 billion in peak sales globally.

Praxis Precision Medicines (NASDAQ: PRAX) is a clinical-stage biopharmaceutical company focused on developing therapies for central nervous system (CNS) disorders. The company's future revenue growth over the next 2-3 years is expected to be driven by the advancement and potential commercialization of its pipeline assets and strategic collaborations.

1. Regulatory Approval and Commercial Launch of Ulixacaltamide for Essential Tremor (ET): Praxis successfully completed its Phase 3 program (Essential3 studies) for ulixacaltamide in treating Essential Tremor, with both studies meeting their primary endpoints and demonstrating significant improvements in patient symptoms. The company has scheduled a pre-New Drug Application (NDA) meeting with the FDA for Q4 2025, with plans to submit its first NDA soon. Analysts project a substantial market potential for ulixacaltamide, with some forecasting "blockbuster status by 2028."

2. Progression and Potential NDA Submission of Relutrigine for SCN2A and SCN8A Developmental and Epileptic Encephalopathies (DEEs): Praxis reported positive top-line results from the Phase 2 EMBOLD trial of relutrigine in SCN2A and SCN8A-DEEs. Following comprehensive discussions with the FDA, Praxis plans an interim analysis of the EMBOLD study in Q1 2025, which, if successful, could support an NDA submission in early 2026. The company is leveraging its Breakthrough Therapy Designation for relutrigine to accelerate its development.

3. Advancement of Vormatrigine through Clinical Trials for Focal Onset Seizures: The company has completed recruitment for the POWER1 study of vormatrigine in focal onset seizures, with topline results anticipated in the first half of 2026. The POWER2 study is also underway, with enrollment expected to be completed in the second half of 2026, marking further progress toward potential future commercialization.

4. Pipeline Expansion and Strategic Partnerships: Praxis continues to develop a robust pipeline of clinical-stage product candidates for CNS disorders, utilizing its proprietary Cerebrum™ and Solidus™ platforms. Historically, the company has generated revenue through collaboration agreements, which can include upfront payments, milestone payments, and royalties on future sales. While the KCNT1 program was in-licensed by UCB in December 2024, leading to a decrease in collaboration revenue for Praxis, future strategic partnerships based on other pipeline assets could serve as significant revenue drivers.
