ProQR Announces an Investor and Analyst Event and Pre-Clinical Data Presentations for QR-110 for LCA10 at the 2016 ARVO Annual Meeting

LEIDEN, Netherlands, April 25, 2016 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (NASDAQ:PRQR) today announced that the company will present pre-clinical data for QR-110 which is being developed for Leber’s congenital amaurosis Type 10 (LCA10) at the 2016 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) in Seattle, WA, May 1 – 5, 2016. QR-110 is the second molecule that will move into clinical development using ProQR’s RNA approach.


The p.Cys998X mutation which is a cause of LCA10 is a point mutation in the CEP290 gene resulting in an activation of a cryptic splice site. QR-110 is a single-stranded, chemically modified RNA oligonucleotide designed to skip the cryptic splice site and thus result in mRNA that codes for a wild-type CEP290 protein. Following intravitreal injection in vivo, QR-110 is demonstrated to reach the outer nuclear layer of the retina, the target tissue. QR-110 is also demonstrated to increase wild-type mRNA in cells with the p.Cys998X mutation. The preclinical data will be presented on poster #1123 - B0295 on May 1st, 3:15 – 5:00pm PT. The abstract is published on the ARVO 2016 annual meeting website.

Investor and analyst event at ARVO

On May 3rd at 7:15pm PT, ProQR management invites investors and analysts to a dinner with Michael Cheetham, PhD, Professor of Molecular and Cell Biology at the Institute of Ophthalmology, University College London to discuss a novel 3-D stratified retinal organoid model for the development of therapeutics for diseases of the retina.

About QR-110

QR-110 is a first-in-class oligonucleotide, designed to address the underlying cause of Leber’s congenital amaurosis Type 10 due to the p.Cys998X mutation in the CEP290 gene. The p.Cys998X mutation is a substitution of one nucleotide in the pre-mRNA that leads to aberrant splicing of the mRNA and non-functional Cep290 protein. QR-110 is designed to restore wild-type CEP290 mRNA leading to the production of wild-type CEP290 protein by binding to the mutated location in the pre-mRNA causing normal splicing of the pre-mRNA. QR-110 is intended to be administered through intravitreal injections in the eye.
