What believers are saying

  • August 6, 2026 FDA mid-cycle meetings showed no major safety issues and no advisory committees.
  • Praxis ended June 30, 2026 with $1.4 billion cash, funding operations into 2028.
  • Commercial hiring and launch systems are already underway for ulixacaltamide and relutrigine.

What critics are saying

  • Vormatrigine missed POWER1 primary endpoint on June 1, 2026, and paused POWER2 enrollment.
  • Relutrigine gained a December 27, 2026 delay after FDA requested major amendment review.
  • An $8.4 billion valuation on pre-commercial assets leaves huge downside if approvals slip.

What makes Praxis Precision Medicines unique

  • Praxis links genetic neuroscience with FDA-backed precision drugs for rare epilepsies and tremor.
  • Ulixacaltamide is first Phase 3 positive essential tremor program, strengthening category leadership.
  • Relutrigine targets SCN2A and SCN8A DEEs, aiming at first-approved therapy status.

FDA accepts Praxis Precision Medicines NDAs amid $92.6M Q1 loss and cash runway to 2028

Praxis Precision Medicines reported a first-quarter 2026 net loss of $92.56 million whilst confirming FDA acceptance of New Drug Applications for ulixacaltamide in Essential Tremor and relutrigine in SCN2A/SCN8A epileptic encephalopathies. Target action dates are set for 2026 and 2027 respectively. The regulatory milestones advance two programmes into formal FDA review alongside ongoing trials for vormatrigine and elsunersen.

The narrative projects $724.1 million revenue and $89.5 million earnings by 2029, requiring 359.5% yearly revenue growth. Analysts' forecasts yield a $449.13 fair value, representing 31% upside to current prices, though the most optimistic projections estimate $2.1 billion revenue by 2029.
