Insights

Financial Analyst

Praxis Precision Medicines' Q2 2024 report shows a strong financial position with $433.8 million in cash and investments, extending their runway into 2027. This is a significant increase from $81.3 million at the end of 2023, primarily due to successful public offerings. The company's net loss decreased slightly to $32.7 million from $34.3 million year-over-year, despite increased R&D expenses. The cash runway provides ample resources for advancing multiple clinical programs, potentially reducing the need for near-term dilutive financing. However, investors should note the continued lack of significant revenue ($0.4 million) and increasing operational costs, typical for a clinical-stage biotech company.

Medical Research Analyst

Praxis is making substantial progress across its pipeline, with four programs potentially reaching registrational phase by 2025. Key upcoming catalysts include:

• Ulixacaltamide's Essential3 Phase 3 interim analysis in Q4 2024
• Relutrigine's EMBOLD Phase 2 topline results in Q3 2024
• PRAX-628's POWER1 Phase 2/3 study initiation in Q4 2024
• PRAX-628's RADIANT Phase 2 study results in 1H 2025

The company's focus on CNS disorders with genetic insights is promising. The potential expansion of relutrigine to broader DEE indications and the comprehensive ENERGY program for PRAX-628 in epilepsy demonstrate a strategic approach to maximizing pipeline value. The high pre-screening numbers for the Essential3 program suggest strong patient interest, which could accelerate enrollment and potentially lead to earlier data readouts.

Market Research Analyst

Praxis's strategic focus on CNS disorders, particularly epilepsy and essential tremor, positions it well in high-unmet-need markets. The company's approach of targeting genetic insights could lead to more effective therapies, potentially commanding premium pricing. The expansion of relutrigine to broader DEE indications could significantly increase its market potential. However, investors should be aware of the competitive landscape in epilepsy and essential tremor, with several other companies developing novel treatments. Praxis's success will depend on demonstrating superior efficacy or safety profiles in upcoming clinical readouts. The company's strong cash position provides a buffer against market volatility, but the lack of near-term revenue streams means investor focus will remain on clinical progress and data readouts through 2025.

BOSTON, Aug. 13, 2024 (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 second quarter 2024.

“In the second quarter we continued to advance our entire portfolio, and we are poised to soon have up to four programs in registrational stage. The Essential3 program continues to progress well, with a pre-planned interim analysis of Study 1 to be conducted later this year. We remain on track for a successful topline readout enabling an NDA filing in 2025,” said Marcio Souza, president and chief executive officer of Praxis. “We look forward to sharing topline results of the EMBOLD study for relutrigine, formerly known as PRAX-562, in SCN2A and 8A patients later this quarter and believe these indications could be the tip of the iceberg for future application of PRAX-562 in other DEEs.”

Mr. Souza added, “We are also excited to build on the encouraging data generated to date with PRAX-628 by executing on the ENERGY program, a comprehensive set of studies, including a new Phase 2 study (RADIANT), with topline data expected in the first half of 2025 in focal and generalized epilepsy. Additionally, with elsunersen having initiated the first arm of its global confirmatory study in Brazil, we anticipate the rapid advancement of all four clinical programs in our portfolio towards regulatory registrations. Our strong cash position, which fully funds Praxis through several important readouts into 2027, enables this momentum.”

Second Quarter 2024 Financial Results:

As of June 30, 2024, Praxis had $433.8 million in cash, cash equivalents, and marketable securities, compared to $81.3 million in cash and cash equivalents as of December 31, 2023. The increase of $352.5 million is primarily due to net proceeds from Praxis’ January 2024 and April 2024 follow-on public offerings plus net proceeds from at-the-market sales of common stock, offset by cash used in operating activities.

Praxis recognized $0.4 million in collaboration revenue during the three months ended June 30, 2024, compared to $0.8 million during the three months ended June 30, 2023. The decrease of $0.4 million is associated with a decrease in revenue recorded under the UCB Collaboration Agreement.

Research and development expenses were $27.3 million for the three months ended June 30, 2024, compared to $25.6 million for the three months ended June 30, 2023. The increase in research and development expenses of $1.6 million was primarily attributable to an increase of $8.1 million in Praxis’ Cerebrum™ platform and a $1.7 million increase in personnel-related costs, primarily offset by a $8.2 million decrease in costs associated with Praxis’ Solidus™ platform. General and administrative expenses were $10.6 million for the three months ended June 30, 2024, compared to $10.1 million for the three months ended June 30, 2023. The increase in general and administrative expenses of approximately $0.5 million was primarily due to increased personnel-related costs.

Praxis reported a net loss of $32.7 million for the three months ended June 30, 2024, including $5.9 million of stock-based compensation expense, compared to $34.3 million for the three months ended June 30, 2023, including $5.8 million of stock-based compensation.

As of June 30, 2024, Praxis had 17.8 million shares of common stock outstanding.

About Ulixacaltamide
Ulixacaltamide is a differentiated and highly selective small molecule inhibitor of T-type calcium channels designed to block abnormal neuronal burst firing in the Cerebello-Thalamo-Cortical (CTC) circuit correlated with tremor activity. Ulixacaltamide, the most advanced program within Praxis’ Cerebrum™ small molecule platform, is currently in late-stage development for the treatment of essential tremor, www.praxisessentialtremor.com. 

About PRAX-628
PRAX-628 is a next-generation, functionally selective small molecule targeting the hyperexcitable state of sodium-channels in the brain that is currently being developed as a once daily, oral treatment for adult focal onset epilepsy. Preclinical data demonstrates PRAX-628 is differentiated from standard of care, with the potential to be best-in-class for focal epilepsy. In vitro, PRAX-628 has demonstrated superior selectivity for disease-state Na_V channel hyperexcitability. In vivo studies of PRAX-628 have demonstrated unprecedented potency in the maximal electroshock seizure (MES) model, a highly predictive translational model for efficacy in focal epilepsy. Data from the PRAX-628-101 study demonstrated that PRAX-628 can be safely dosed in healthy subjects to greater than 15 times the predicted human equivalent of the rodent MES EC50. 

About Elsunersen (PRAX-222)
Elsunersen is an antisense oligonucleotide (ASO) designed to selectively decrease SCN2A gene expression, directly targeting the underlying cause of early-seizure-onset SCN2A-DEE to treat seizures and other symptoms in patients with gain-of-function SCN2A mutations. In vitro studies of elsunersen have demonstrated reduction in both SCN2A gene expression and protein levels. In vivo, elsunersen has demonstrated significant, dose-dependent reduction in seizures, improvement in behavioral and locomotor activity and increased survival in SCN2A mouse models, with potential to be the first disease-modifying treatment for SCN2A-DEE. Elsunersen has received Orphan Drug Designation (ODD) and Rare Pediatric Disease Designation (RPD) from the FDA, and ODD and PRIME designations from the European Medicines Agency (EMA) for the treatment of SCN2A-DEE. The Elsunersen program is ongoing under a collaboration with Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), and RogCon, Inc. To learn more about the EMBRAVE study, please visit https://www.embravestudy.com/.

About Relutrigine (PRAX-562)
Relutrigine is a first-in-class small molecule in development for the treatment of developmental and epileptic encephalopathy (DEE) as a preferential inhibitor of persistent sodium current, shown to be a key driver of seizure symptoms in early onset SCN2A-DEE and SCN8A-DEE. Relutrigine’s mechanism of sodium channel blocking is consistent with superior selectivity for disease state sodium channel (NaV) channel hyperexcitability. In vivo studies of relutrigine have demonstrated dose-dependent inhibition of seizures up to complete control of seizure activity in SCN2A, SCN8A and other DEE mouse models. Relutrigine has been generally well-tolerated in three Phase 1 studies and has demonstrated biomarker changes indicative of NaV channel blocking effects. Relutrigine has received ODD and RPD from the FDA, and ODD from the European Medicines Agency for the treatment of SCN2A-DEE and SCN8A-DEE. To learn more about the EMBOLD study, please visit https://www.emboldstudy.org/.
