PRAX-628 Phase 1 study results support preclinical profile indicating potential for best-in-class-efficacy for focal epilepsy

Cash and investments of $85.8 million as of March 31, 2023 supports runway into 2Q24

BOSTON, May 11, 2023 (GLOBE NEWSWIRE) -- Praxis Precision Medicines, Inc. (NASDAQ: PRAX), a clinical-stage biopharmaceutical company translating genetic insights into the development of therapies for central nervous system (CNS) disorders characterized by neuronal excitation-inhibition imbalance, today provided a corporate update and reported financial results for the first quarter 2023.

“Each of our four clinical-stage programs has made meaningful progress this year and we anticipate additional value inflecting milestones throughout the pipeline in the coming months,” said Marcio Souza, president and chief executive officer of Praxis. “We shared positive topline results earlier today from the Phase 1 study of our next-generation, functional-state selective small molecule, PRAX-628, and believe that this program has the potential to change the treatment paradigm for people living with focal epilepsy. We look forward to initiating a PRAX-628 Phase 2 study in focal epilepsy later this year, and also plan to share results from our PRAX-562 and PRAX-222 programs in rare, genetic epilepsies. Finally, we eagerly anticipate the upcoming ulixacaltamide End-of-Phase 2 FDA meeting in June and intend to start a Phase 3 program in essential tremor shortly thereafter.”

Recent Business Highlights and Upcoming Milestones:

Cerebrum™ Small Molecule Platform

  • Praxis announced topline results from the ulixacaltamide (PRAX-944) Phase 2 Essential1 study for the treatment of moderate to severe essential tremor (ET) in March 2023. An end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) is scheduled for June 2023. Based upon the observed efficacy and safety profile, Praxis intends to initiate the ulixacaltamide Phase 3 program for the treatment of ET in the second half of 2023 following FDA feedback on the clinical registration plan and alignment on the overall development program.
  • The Company plans to present additional results from the Essential1 study at upcoming medical conference meetings and company events:

    • Essential1 topline results poster at the World Congress on Parkinson’s Disease and Related Disorders 2023 (IAPRD) in Chicago, IL on Monday, May 15, 2023 at 12:15 p.m. CDT
    • Essential1 results presentation and scientific talk at the 2nd International Tremor Conference (ITC) in New York, NY on Thursday, May 18, 2023 at 4:20 p.m. EDT
    • Essential1 results presentation and key opinion leader (KOL) company hosted event (details to follow)

Solidus™ Antisense Oligonucleotide (ASO) Platform

  • Praxis is conducting the first dose cohort (Part 1) of the PRAX-222 EMBRAVE study for the treatment of pediatric patients with early-onset SCN2A-DEE in the U.S. Following collection of the safety and efficacy data from Part 1 of the EMBRAVE study, the data will be evaluated and submitted to the FDA to support further dose escalation. Part 1 of the EMBRAVE study is a 21-week open label cohort, in which participants will receive PRAX-222 for up to 13 weeks, designed to determine the safety and tolerability of intrathecal delivery of PRAX-222. Topline results are expected in the second half of 2023.

First Quarter 2023 Financial Results:

As of March 31, 2023, Praxis had $85.8 million in cash, cash equivalents and marketable securities, which is expected to fund operations into the second quarter of 2024.

Praxis recognized $0.7 million in collaboration revenue during the three months ended March 31, 2023 related to its Option and License Agreement with UCB.

Research and development expenses were $25.5 million for the three months ended March 31, 2023, compared to $52.7 million for the three months ended March 31, 2022. The decrease in research and development expenses of $27.1 million was primarily attributable to $25.3 million in decreased expenses related to the Company's Cerebrum™ and Solidus™ platforms and a $3.0 million decrease in personnel-related expenses.

General and administrative expenses were $13.3 million for the three months ended March 31, 2023, compared to $16.2 million for the three months ended March 31, 2022. The decrease in general and administrative expenses of approximately $2.9 million was primarily due to a decrease in consulting and insurance-related costs as well as a decrease in personnel-related expenses.

Praxis reported a net loss of $37.5 million for the three months ended March 31, 2023, including $7.6 million of stock-based compensation expense, compared to $68.7 million for the three months ended March 31, 2022, including $7.9 million of stock-based compensation expense.
