LEIDEN, Netherlands & CAMBRIDGE, Mass., February 11, 2022 -- ProQR Therapeutics N.V. (Nasdaq: PRQR) (the “Company”), a company dedicated to changing lives through the creation of transformative RNA therapies for genetic eye diseases, today announced its pivotal Phase 2/3 Illuminate trial of sepofarsen for the treatment of CEP290-mediated Leber congenital amaurosis 10 (LCA10) did not meet its primary endpoint of Best Corrected Visual Acuity (BCVA) at Month 12.
“Given the results observed in earlier studies of sepofarsen, the Illuminate trial results are unexpected and disappointing, especially for people living with LCA10,” said Daniel A. de Boer, Founder and CEO of ProQR Therapeutics. “ProQR was founded with the goal of developing RNA therapies for patients with high unmet medical need, and we will continue to advance our robust pipeline of therapies for genetic eye disease. We are deeply grateful to all of the participants, their supporters, and investigators who participated in the Illuminate study.”
“LCA10 is a devastating, very difficult-to-treat retinal disease resulting in blindness, for which there are no therapies,” said Dr. Bart Leroy, Head of the Ophthalmology Department at Ghent University Hospital and Professor of Ophthalmology and Ophthalmic Genetics at Ghent University, Ghent, Belgium and Attending Physician for Ophthalmic Genetics and Retinal Degenerations at The Children's Hospital of Philadelphia. “We will continue to work with ProQR to understand the data as they work to advance therapies for inherited retinal diseases.”
Illuminate, a randomized, sham-controlled trial, enrolled 36 participants aged eight years or older with genetically confirmed LCA10 due to the c.2991+1655A>G (p.Cys998X) mutation in the CEP290 gene, at 14 study sites in 9 countries. Participants were randomized to three equal groups (1:1:1) of the target registration dose sepofarsen (160 μg/80 μg loading dose/maintenance doses), a low dose of sepofarsen for masking (80 μg/40 μg loading dose/maintenance doses), or sham procedure, with sepofarsen administered via intravitreal injection and the sham procedure mimicking an injection with no drug or injection given.
Key findings from the top-line results:
| · | At Month 12, the mean change from baseline in BCVA in the 160/80 μg dose group was -0.11 logMAR (p=0.96), in the 80/40 μg group -0.13 logMAR (p=0.97), and in the sham group -0.12 logMAR. P values are treatment group vs. sham, ANCOVA. | |
| · | For secondary endpoints full-field stimulus test (FST) and mobility, there was also no difference between the treated and sham groups in the top-line analysis. | |
| · | Sepofarsen was observed to be generally well-tolerated. Consistent with the findings observed in the Phase 1/2 trial, cataracts, CME, and retinal thinning were observed. |
“This was not the outcome we had hoped for and we share in the disappointment many are feeling in the community,” said Benjamin R. Yerxa, Chief Executive Officer at the Foundation Fighting Blindness. “We will continue to work alongside ProQR to learn more from the ongoing analyses and as they work to advance RNA therapies to potentially help children, adults, and families who are affected by rare genetic eye diseases.”

About Leber Congenital Amaurosis 10 (LCA10)
Leber congenital amaurosis (LCA) is the most common cause of blindness due to genetic disease in children. It consists of a group of diseases of which LCA10 is the most frequent and one of the most severe forms. LCA10 is caused by mutations in the CEP290 gene, of which the c.2991+1655A>G (p.Cys998X) mutation has the highest prevalence. LCA10 leads to early loss of vision causing most people to lose their sight in the first few years of life. To date, there are no treatments approved that treat the underlying cause of the disease. Approximately 2,000 people in the Western world have LCA10 because of this mutation.
About Sepofarsen
Sepofarsen (QR-110) is an investigational RNA therapy designed to restore vision in Leber congenital amaurosis 10 due to the c.2991+1655A>G mutation (p.Cys998X) in the CEP290 gene. The mutation leads to aberrant splicing of the mRNA and non-functional CEP290 protein. Sepofarsen is designed to enable normal splicing, resulting in restoration of normal (wild type) CEP290 mRNA and subsequent production of functional CEP290 protein. 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 and rare pediatric disease designation from the FDA as well as access to the PRIME scheme by the EMA.
