Key updates:

ProQR Therapeutics N.V. (Nasdaq:PRQR), today announced a Research & Development Day for investors hosted by the Company’s management team and several key opinion leaders. The event will also be webcast.

The R&D Day will feature presentations by ProQR management on the progress on its pipeline, including a review and introduction of several near- and medium term value drivers. In addition, several leading opinion leaders will discuss the state of the art in research and development on critical areas of the company’s pipeline including CF, inherited blindness, debilitating skin diseases and RNA technologies.

“Following a significant effort to build a diversified product portfolio over the last 5 years, we now have a pipeline that includes two clinical programs, one pre-clinical program and two programs ready to enter development,” said Daniel de Boer, CEO of ProQR. “We’re looking forward to provide an update on the development programs and shine some light on the promising pipeline of discovery programs and a novel RNA editing technology.”

“Over the last several decades the RNA space has matured significantly. With our management and scientific resources we believe we are well positioned to unlock the field’s substantial potential,” said Gerard Platenburg, Chief Innovation Officer at ProQR. “We apply the use of RNA based therapeutics with the goal to make an impact for patients with several severe genetic diseases. Our scientific efforts have also led to a novel proprietary RNA editing platform, called Axiomer, which in our view is the next step in RNA therapeutics, on which we will elaborate at the R&D day.”
