LEIDEN, Netherlands & CAMBRIDGE, Mass., May 08, 2025 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (Nasdaq: PRQR) (ProQR), a company dedicated to changing lives through transformative RNA therapies based on its proprietary Axiomer RNA editing technology platform, today reported its financial and operating results for the first quarter ended March 31, 2025, and provided a business update.

“ProQR entered 2025 in a position of strength, with solid fundamentals, a well-capitalized balance sheet, and a clear focus on execution,” said Daniel A. de Boer, Founder and Chief Executive Officer of ProQR.“We remain on track to submit the CTA for our lead RNA editing program, AX-0810 targeting NTCP for cholestatic diseases, in Q2 2025, with our first clinical data readout expected in Q4 – key milestones for our lead Axiomer pipeline program that we believe will drive significant value for stakeholders. I'm delighted that we further strengthened our leadership team with the recent appointments of Chief Financial Officer Dennis Hom and Chief Medical Officer Dr. Cristina Lopez Lopez, bringing deep financial and translational clinical development expertise to support ProQR's next phase of growth.”

Recent Progress

• In April, ProQR announced the appointments of Dennis Hom as Chief Financial Officer and Cristina Lopez Lopez, MD, PhD as Chief Medical Officer . These key leadership appointments support the advancement of the Company's Axiomer platform technology and pipeline of RNA editing programs as it enters the clinical stage.
• Advancing AX-0810 toward CTA filing, on track for Q2 2025. AX-0810 is ProQR's lead Axiomer RNA editing pipeline program. By modulating NTCP, AX-0810 aims to reduce bile acid accumulation in hepatocytes and address the root cause of cholestatic liver diseases. The program remains on track for a Clinical Trial Application (CTA) filing in Q2 2025, with the initial clinical assessment planned in healthy volunteers.
• In March, ProQR participated in the RNA Editing Gordon Research Conference in Lucca, Italy, presenting "Developing AxiomerTM RNA Editing Technology Towards Application in Liver and CNS Disease" .
• Accepted scientific abstracts underscore ProQR's leadership in RNA editing. ProQR will present multiple abstracts at the upcoming American Society of Gene & Cell Therapy (ASGCT) Annual Meeting, taking place May 13-17, 2025 in New Orleans. These presentations will highlight the Company's proprietary Axiomer RNA editing platform and pipeline programs, including:
  • Oral Presentation (333):“ADAR-Mediated RNA Editing of SLC10A1 (NTCP) as a Therapeutic Approach to Reduce Liver Bile Acid Re-Uptake in Cholestatic Diseases”
  • Poster Presentation (AMA1324):“ADAR-Mediated RNA Editing-Based Correction of PNPLA3|148M Functionality to Address Hepatic Steatosis”
  • Poster Presentation (AMA1427):“ADAR-Mediated RNA Editing of Premature Termination Codon Results in Functional Correction in MECP2 for Rett Syndrome”

Anticipated Upcoming Events

• AX-0810 targeting NTCP for Cholestatic diseases
  • Q2 2025 Clinical Trial Application (CTA) submission
  • Q4 2025 first clinical target engagement and biomarker data in healthy volunteers
• AX-2402 targeting MECP2 (R270X) for Rett Syndrome
  • 2025 clinical candidate selection
  • 2026 clinical trial initiation and topline data readout
• AX-2911 targeting PNPLA3 for MASH
  • 2025 clinical candidate selection
  • 2026 clinical trial initiation and topline data readout
• AX-1412 targeting B4GALT1 for Cardiovascular diseases
  • mid-2025 update on optimization for GalNAc delivery
• Continue to execute on partnership with Eli Lilly and Company (Lilly), with potential data updates, milestone income from the existing partnership, and an option to exercise for an additional five targets for expansion to a total of 15 targets, which would result in a $50 million opt-in payment to ProQR.
• ProQR may selectively form new partnerships, which could include multi-target discovery alliances, or product alliances on specific programs.

About Axiomer ^TM

ProQR is pioneering a next-generation RNA base editing technology called Axiomer^TM, which could potentially yield a new class of medicines for diverse types of diseases. Axiomer^TM“Editing Oligonucleotides”, or EONs, mediate single nucleotide changes to RNA in a highly specific and targeted way using molecular machinery that is present in human cells called ADAR (Adenosine Deaminase Acting on RNA). Axiomer^TM EONs are designed to recruit and direct endogenously expressed ADARs to change an Adenosine (A) to an Inosine (I) in the RNA – an Inosine is translated as a Guanosine (G) – correcting an RNA with a disease-causing mutation back to a normal (wild type) RNA, modulating protein expression, or altering a protein so that it will have a new function that helps prevent or treat disease.

About ProQR

ProQR Therapeutics is dedicated to changing lives through the creation of transformative RNA therapies. ProQR is pioneering a next-generation RNA technology called Axiomer^TM, which uses a cell's own editing machinery called ADAR to make specific single nucleotide edits in RNA to reverse a mutation or modulate protein expression and could potentially yield a new class of medicines for both rare and prevalent diseases with unmet need. Based on our unique proprietary RNA repair platform technologies we are growing our pipeline with patients and loved ones in mind.
