ProQR Announces First Quarter 2026 Operating and Financial Results

May 12, 2026 7:00 AM

LEIDEN, Netherlands & CAMBRIDGE, Mass., May 12, 2026 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (Nasdaq: PRQR) (ProQR), a clinical-stage 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 quarter ended March 31, 2026, and provided a business update.

“We are on track to deliver multiple clinical readouts within our current runway, including target engagement data for AX-0810 in the second quarter,” said Daniel A. de Boer, Founder and Chief Executive Officer of ProQR. “We have refined our initial development strategy for AX-0810 to prioritize biliary atresia, where we believe we can generate the most meaningful clinical data in this target patient population, while maintaining flexibility to explore additional indications, including PSC, as the program advances. We also continue to advance our platform more broadly to bring RNA editing therapies to patients.”

Recent Progress and Anticipated Upcoming Events

AX-0810 Advancing Toward Target Engagement Data
AX-0810, ProQR’s lead RNA editing program targeting NTCP, remains on track to report target engagement data from healthy volunteers in the second quarter of 2026.

The Company has selected biliary atresia (BA) as the initial indication for Phase 2 development, based on strong biological rationale and high unmet need. As part of this strategy, ProQR plans to conduct an investigator-initiated trial (IIT) in pediatric participants with BA in China instead of the previously planned adult participant PSC cohort in its Phase 1 program. While PSC remains of interest as a potential setting for broader development, the Company is prioritizing a BA-focused IIT to provide a more direct path to early, data generation in the target patient population, prior to initiation of a Phase 2 study. ProQR is working with investigators to initiate the IIT, with initial clinical data targeted for H1 2027.

Pipeline Expansion and Upcoming Catalysts
ProQR continues to expand its pipeline, with multiple programs advancing toward the clinic:

Scientific Conference Presentations
ProQR is presenting multiple presentations at scientific conferences in May, including TIDES USA, the American Society of Gene & Cell Therapy (ASGCT) Annual Meeting, the RNA Society Annual Meeting, and the European Association for the Study of the Liver (EASL) Congress. Collectively, these presentations expand the body of evidence supporting the breadth and versatility of the Company’s Axiomer RNA editing platform including applications across multiple tissues and disease areas.

Advancing the Axiomer™ Platform

ProQR continues to enhance its Axiomer platform through the integration of AI-enabled discovery and high-throughput screening to accelerate the design and optimization of RNA editing therapeutics.

Board Nomination and Annual General Meeting

Dr. Lykke Hinsch Gylvin, Chief Medical Officer and Head of Global Medicine at Boehringer Ingelheim, has been nominated for appointment to the ProQR Board of Directors, subject to shareholder approval at the upcoming Annual General Meeting, scheduled for June 2, 2026. Dr. Hinsch Gylvin is a seasoned pharmaceutical executive with more than 20 years of global leadership experience spanning all phases of drug development in a broad range of therapeutic areas.

About Axiomer™

ProQR is pioneering a next-generation RNA base editing technology called Axiomer™, which could potentially yield a new class of medicines for diverse types of diseases. Axiomer™ “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™ 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™, 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.
