Company to host conference call and webcast today at 8:00 a.m. EDT
- The European Commission (EC) approved the 2mg/kg every-4-weeks (E4W) dosing regimen for Elfabrio® in adults living with Fabry disease providing a meaningful reduction in treatment burden without compromising efficacy
- The EC approval triggered the Company’s entitlement to a $25.0 million milestone payment from Chiesi, strengthening the Company’s cash position and supporting an expected cash balance of approximately $50.0 million by April 2026
- Based on current estimates, management expects total revenues in 2026 to range from approximately $78.0 million to $83.0 million including the $25.0 million payment referenced above
- The Phase 2 clinical trial of PRX–115 is actively enrolling; the Company believes PRX-115 has the potential to be a best-in-class therapy, improving uncontrolled gout patients’ compliance and outcomes
- Continued strategic focus on rare renal diseases to build a pipeline through innovation and partnerships
- In March 2026, the European Commission (EC) approved a novel 2mg/kg every-4-weeks (E4W) dosing regimen for Elfabrio in adults with Fabry disease who are stable on an enzyme replacement therapy (ERT).
- This decision followed the positive opinion from the Committee for Medicinal Products for Human Use (CHMP) recommending this additional dosing regimen.
- The E4W regimen provides a potentially meaningful reduction in treatment burden without comprising efficacy, one of the more common unmet needs in Fabry disease, and the 50% infusion frequency reduction represents a quality of life improvement for Fabry patients in the EU.
- This approval was supported by the BRIGHT study and long-–term extension data, which demonstrated that the E4W dosing regimen maintained clinical and renal outcomes in stable patients.
- Further support came from an updated Population Pharmacokinetics (PopPK) model and exposure–response analysis, which leveraged data from multiple clinical studies.
- Elfabrio is now the only ERT approved for E4W dosing to treat Fabry in the EU – strengthening its competitive positioning and potential market share expansion.
- The FDA-approved dosing regimen for Elfabrio in the United States remains 1mg/kg every 2 weeks.
- Actively enrolling, and the first patients have been randomized, in the RELEASE Phase 2 clinical trial of PRX–115 (NCT07280156), a recombinant PEGylated uricase.
- The RELEASE study builds on favorable Phase 1 clinical trial results, where PRX–115 was generally well–tolerated and demonstrated rapid, durable serum urate reduction below target levels across all cohorts.
- PRX–115 is designed as a potential best–in–class, long–acting therapy, with a possible E4W dosing schedule with or without an immunomodulator, or less frequent dosing with an immunomodulator, aiming to improve adherence and durability of response for patients with uncontrolled gout.
- By addressing immunogenicity challenges and enabling more flexible dosing intervals, the Company believes PRX–115 is well-positioned to capture a meaningful share in the uncontrolled gout segment, where even modest penetration represents significant commercial opportunity.
- The Company anticipates top-line results in the second half of 2027.
- The Company recently received an allowance from the US Intellectual Property Office (USPTO) for Patent Application No. 18/035,149 entitled “MODIFIED URICASE AND USES THEREOF” protecting the PEGylated uricase.
- The Company is deepening its focus on rare renal diseases by advancing PRX–119, its long–acting DNase I program.
- The Company is also collaborating with Secarna to discover RNA–based therapeutic candidates that may complement its ProCellEx platform.
- Support our commercial partnerships
- Advance PRX–115 as a potential best–in–class therapy for uncontrolled gout
- Advance rare renal programs leveraging the Company’s R&D strengths
- Total revenue in 2026 to range from approximately $78.0 million to $83.0 million including the $25.0 million milestone which the Company is entitled to from Chiesi.
- Full–year 2026 revenues from sales of Elfabrio without milestones to range from approximately $33.0 million to $35.0 million.
- Full–year 2026 revenues from sales of Elelyso to range from approximately $20.0 million to $23.0 million.
- Revenues from selling goods were $51.8 million for the year ended December 31, 2025, a decrease of $1.2 million (2%) versus $53.0 million in 2024, driven primarily by a $6.8 million decline in sales to Chiesi to $22.5 million, partially offset by an increase in sales to Pfizer Inc., or Pfizer (up $5.6 million to $18.2 million), and to Fundação Oswaldo Cruz, or Fiocruz (Brazil) (up $0.03 million to $11.1 million).The decrease in revenues recorded from sales to Chiesi in 2025 resulted primarily from a change in the average net selling price of drug product in the applicable territory as well as changes in the quantities the Company sold to Chiesi’s inventory. The increase in revenues recorded from sales to Pfizer resulted primarily from increased purchases of Elelyso by Pfizer to address unexpected manufacturing issues on their end.
- Revenues from license and R&D services were $0.9 million in 2025, up $0.5 million (125%) from $0.4 million in 2024. Revenues from license and R&D services are comprised primarily of revenues recognized in connection with the Company’s agreements with Chiesi. Other than potential regulatory milestone payments that may become payable, the Company expects to generate minimal revenues from license and R&D services.
- Cost of goods sold were $27.0 million in 2025, an increase of $2.7 million (11%) versus $24.3 million in 2024. The increase in cost of goods sold was primarily the result of increase in sales to Pfizer and Fiocruz (Brazil) partially offset by a decrease in sales to Chiesi.
- Research & development (R&D) expenses totaled $19.6 million in 2025 (vs. $13.0 million in 2024) up $6.6 million (51%). The increase in research and development expenses resulted primarily from preparations for the RELEASE Phase 2 study of PRX-115. The Company expects to continue to incur significant and increasing research and development expenses as it progresses with the RELEASE study and commences more advanced stages of preclinical and clinical trials for certain of its other product candidates.
- Selling, general and administrative (SG&A) expenses were $11.7 million in 2025, a decrease of $0.5 million (4%) from $12.2 million in 2024. The decrease resulted primarily from a decrease in share-based compensation.
- Financial income (expenses), net was an expense of $0.1 million in 2025 versus income of $0.2 million in 2024, resulting primarily from approximately $1.3 million in exchange rate expense effects, partially offset by approximately $1.0 million in reduced interest expense following the full repayment of the then outstanding senior secured convertible promissory notes, including all outstanding principal and interest, in September 2024.
- Taxes on income were $1.0 million in 2025, a decrease of $0.2 million (18%) compared to $1.2 million in 2024, the tax expenses resulted primarily from taxes on income mainly derived from global intangible low-taxed income (GILTI) resulting primarily from limitations under U.S. Internal Revenue Code Section 174 (the U.S. Tax Cuts and Jobs Act).
- Cash, cash equivalents, and short–term bank deposits were $30.3 million on December 31, 2025.
- Net loss for the year ended December 31, 2025, was approximately $6.6 million, or $(0.08) per share, basic and diluted, compared to net income of $2.9 million or $0.04 per share, basic and diluted, for the same period in 2024.
