ProQR Announces Planned Changes to Board Composition
LEIDEN, Netherlands & CAMBRIDGE, Mass., February 9, 2026 – 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 announced that Dinko Valerio, a co-founder of the Company, and Alison Lawton will rotate off the Board at the Company’s next Annual General Meeting (AGM) as their terms conclude.
The planned changes to ProQR’s Board composition at its 2026 AGM reflect the Company’s development as it advances its clinical programs, as well as its ongoing commitment to strong corporate governance and long-term succession planning. An executive search firm has been engaged to assist ProQR in identifying candidates to be nominated to the Board to support long-term value creation for all its stakeholders.
“On behalf of the Board, I would like to sincerely thank Dinko for his leadership, which has played a central role in shaping ProQR’s vision and strategy, and Alison for her insight, dedication, and many valuable contributions to the Company during her tenure,” said James Shannon, MD, Chairperson of the Board of ProQR Therapeutics. “Their efforts have had a meaningful impact on ProQR, and we are deeply grateful for their expertise.”
“Dinko and Alison have brought meaningful perspective and presence to the Board,” said Daniel A. de Boer, Founder and Chief Executive Officer of ProQR. “I have greatly appreciated their insights and contributions, and I look forward to continuing to work closely with the Board as we execute our strategy and advance our clinical and pipeline programs.”
As part of its ongoing governance practices, the Board regularly reviews its composition to ensure it maintains an appropriate balance of skills, experience, and perspectives to support ProQR’s long-term strategic objectives. This process has resulted in the appointment of two new Board members in the last three years.
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.
