Praxis Precision Medicines Announces Closing of Financing and Reiterates Corporate Priorities

Strong demand for financing including full exercise of overallotment option with net proceeds of $63.3 million

Cash runway extended into Q1 2025

Phase 2 Photoparoxsymal Response (PPR) study to evaluate PRAX-628 expected to read-out by YE 2023

Plan to begin ulixacaltamide Phase 3 enrollment in Q4 2023 to support a 2025 NDA filing

BOSTON, June 22, 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 announced the closing of the underwritten public offering of shares of common stock and pre-funded warrants, including the full exercise of the underwriters’ overallotment option. The net proceeds from the offering are $63.3 million, after deducting underwriting discounts and commissions and estimated offering expenses. Together with the Company’s existing cash, cash equivalents and marketable securities, this extends the cash runway into the first quarter of 2025. The proceeds will be used to advance the development of ulixacaltamide into two Phase 3 studies for essential tremor, to continue clinical development of PRAX-562, PRAX-222 and PRAX-628 for various epilepsies, and for working capital and other general corporate purposes.

The Company has initiated a study evaluating PRAX-628 in photo-sensitive epilepsy patients, also known as a PPR study, with expected readout by year end. Similar studies have shown a positive correlation to anti-seizure medicines (ASMs) used to treat focal epilepsy. With this study, Praxis plans to validate the mechanism of action of PRAX-628 and inform the study design for its Phase 2b program.

Praxis remains on-track for reading out the Phase 2 Study for PRAX-562 and the first cohort for PRAX-222 in DEEs by year end.

“This financing provides the means to continue advancing our portfolio in movement disorders and in epilepsy closer to patients, with a number of catalysts this year,” said Marcio Souza, president and chief executive officer of Praxis. “We are excited to advance our Phase 3 program in essential tremor, while also initiating the PPR study to inform and de-risk our program in focal epilepsy. Additionally, we are pleased to have received support from both existing and new investors.”
