LEIDEN, the Netherlands & CAMBRIDGE, Mass., Oct. 07, 2019 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (Nasdaq:PRQR), a company dedicated to changing lives through the creation of transformative RNA medicines for severe genetic rare diseases, today announced that management will present and discuss top-line results from the Phase 1/2 study of sepofarsen on October 10, ahead of the American Academy of Ophthalmology's annual meeting to be held in San Francisco, CA, U.S.

The results will be announced in a press release on October 10, 2019 and management will host an investor conference call at 8:00 a.m. ET that same day to discuss the results in detail.

About the PQ-110-001 Phase 1/2 trial

PQ-110-001 is a first-in-human open-label trial that enrolled 5 children (age 6 - 17 years) and 6 adults (≥ 18 years) who have LCA10 due to one or two copies of the p.Cys998X mutation in the CEP290 gene. Patients are receiving four intravitreal injections of sepofarsen into one eye; one injection every three months, with the other eye remaining untreated. Two dose levels are being tested, 80 μg (160 μg loading dose) and 160 μg (320 μg loading dose). The trial is being conducted at three specialized centers with significant expertise in genetic retinal disease: the University of Iowa, Iowa City, Iowa, U.S., the Scheie Eye Institute at the University of Pennsylvania, Philadelphia, U.S., and the Ghent University Hospital, Ghent, Belgium.

The primary objectives of the PQ-110-001 trial are safety and tolerability. Secondary objectives include pharmacokinetics, as well as restoration/improvement of visual function and retinal structure through ophthalmic endpoints, such as visual acuity (BCVA), mobility course, full field stimulus testing (FST), ocular instability (OCI), optical coherence tomography (OCT), and pupillary light reflex (PLR). Changes in quality of life in the trial subjects are also being evaluated.

About Sepofarsen

Sepofarsen (QR-110) is a first-in-class investigational RNA-based oligonucleotide designed to address the underlying cause of Leber’s congenital amaurosis 10 due to the p.Cys998X mutation (also known as the c.2991+1655A>G 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. Sepofarsen is designed to restore normal (wild-type) CEP290 mRNA leading to the production of normal CEP290 protein by binding to the mutated location in the pre-mRNA causing normal splicing of the pre-mRNA. Sepofarsen is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the United States and the European Union and received fast-track designation from the FDA as well as PRIME access by the EMA.
