Praxis Precision Medicines Inc. announced clinical updates at the American Epilepsy Society Annual Meeting on December 6, 2025, highlighting positive results from the EMBOLD study of relutrigine in patients with developmental and epileptic encephalopathies (DEEs). The results, already presented at the meeting, showed a 53% placebo-adjusted reduction in seizures and a 66% increase in motor seizure-free days over 16 weeks. Clinician and caregiver assessments indicated statistically significant improvements in alertness, communication, and seizure severity. Praxis stated that it will meet with the FDA to discuss next steps for a potential New Drug Application (NDA) for relutrigine and will determine NDA filing timing following the meeting. The company also reported completion of recruitment for the POWER1 pivotal study in focal onset seizures (FOS), with additional studies planned or ongoing.
