***Elsunersen***

On December 9, 2025, Praxis Precision Medicines, Inc. (the "Company") announced the completion of a Type C meeting with the U.S. Food and Drug Administration (the "FDA") and agreement to immediately convert the EMBRAVE3 registrational study of elsunersen in early-onset SCN2A developmental and epileptic encephalopathy ("DEE") into a single-arm study where all patients will receive elsunersen for 24 weeks, followed by an open-label extension.

*Key Changes to EMBRAVE3*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The current study has been immediately converted from a double-blind, sham-controlled study to a single-arm, baseline-controlled study, enrolling 30 patients reduced from 40 patients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All patients currently in screening will be assigned to receive elsunersen.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The primary analysis will be the change from baseline in countable motor seizures.

*Update on EMBRAVE Study Status*

The EMBRAVE Study Part A enrolled 9 patients randomized 3:1 to elsunersen or placebo/sham for 20 weeks, followed by a blinded transition to elsunersen for up to 2 years in an open-label extension. The Company expects to complete Part A and disclose the topline results in the first half of 2026.

***Relutrigine***

On December 11, 2025, the Company announced the completion of the planned discussion with the FDA, leading to the confirmation to file a New Drug Application for relutrigine in SCN2A and SCN8A DEEs in early 2026.

**Forward-Looking Statements**

This Current Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other federal securities laws, including statements regarding the clinical development of elsunersen and regulatory interactions and submissions for relutrigine. The forward-looking statements included in this Current Report are subject to a number of risks, uncertainties and assumptions, including, without limitation, uncertainties inherent in clinical trials, the expected timing of submission for regulatory approval or review by governmental authorities and other risks as described in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, its Quarterly Report on Form 10-Q for the quarter ended June 30, 2025 and its other filings with the Securities and Exchange Commission.
