LEIDEN, Netherlands & CAMBRIDGE, Mass., Feb. 24, 2022 (GLOBE NEWSWIRE) -- 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 reported its financial and operating results for the fourth quarter and full year ended December 31, 2021, and provided a business update.
“Following the disappointing readout of top-line results from the Illuminate trial of sepofarsen, we are conducting a comprehensive analysis of the data with the goal of providing an update on any potential next steps with this program and our overall strategy in Q2,” said Daniel A. de Boer, Founder and CEO of ProQR. “Based on the previous data we have reported, we remain very confident in our RNA approach and will continue to follow the data to determine how to best position ProQR for success.”
De Boer continued, “In the coming year, we anticipate sharing data from our Helia extension trial of ultevursen, as well as the initial data from our QR-504a biomarker study. In parallel, our Sirius and Celeste trials of ultevursen are enrolling patients with USH2A-mediated Usher syndrome and retinitis pigmentosa. Beyond our clinical pipeline, we are excited by the potential of our next-generation Axiomer RNA editing technology. In addition to using this platform to develop therapies for our wholly-owned pipeline, we anticipate continuing to develop collaborations on a target-by-target basis, similar to the partnership with Lilly we announced last fall. ProQR is in a strong financial position with a cash runway into mid-to-late 2024 and we will continue to be diligent with our capital, as we work to advance RNA therapies for individuals with high unmet need in genetic eye diseases.”
Business Operations and Program Updates
- In February, the Company announced that the Phase 2/3 Illuminate trial of sepofarsen for CEP290-mediated Leber congenital amaurosis 10 (LCA10) did not meet the primary endpoint, nor notable secondary endpoints. No benefit was observed in either treatment arm versus sham. Additional analyses are ongoing and an update is expected in Q2 2022.
- In December, the first patients were dosed in the pivotal Phase 2/3 Sirius and Celeste trials of ultevursen (formerly QR-421a) for USH2A-mediated Usher syndrome and retinitis pigmentosa. The Company has begun enrolling eligible individuals from the Phase 1/2 Stellar trial in the Helia open-label extension study, which will include multiple dose treatments for both eyes. The Company expects to share an update from the Helia study by year end 2022.
- In November, the Company reported initial clinical data from the Phase 1/2 Aurora trial of QR-1123 for RHO-mediated autosomal dominant retinitis pigmentosa (adRP) in Q4. A single dose of QR-1123 (gapmer) showed early evidence of target engagement and was well tolerated with no serious adverse events. Based on these findings, ProQR plans to advance QR-1123 to a repeated dose Phase 2 trial in 2022.
- The Fuchs Focus study of QR-504a for Fuchs Endothelial Corneal Dystrophy (FECD) is currently open for enrollment. This study is evaluating safety, tolerability, and molecular biomarker(s), i.e., target engagement, in the corneal endothelium following a single intravitreal injection of QR-504a in patients with FECD who are scheduled for corneal transplant with concurrent lens replacement. ProQR anticipates reporting initial data from this trial in 2022.
- ProQR has been further optimizing the Axiomer® Editing Oligonucleotide (EON) designs and will develop selected genetic eye disease targets with Axiomer®. The Company anticipates providing further guidance on this in H2 2022.
- In February 2022, Theresa Heggie assumed the role of Chief Operating Officer. Theresa joined ProQR in 2021 as Chief Commercial Officer after serving as a member of the Supervisory Board since 2019. Previously, she served as Chief Executive Officer of Freeline Therapeutics and held senior roles with Alnylam and Shire.
- In December, ProQR amended its convertible debt financing agreement entered into in 2020 with Kreos and Pontifax. $30 million was drawn by the Company at closing of the amendment.
- In September, Eli Lilly and Company (Lilly) and ProQR entered into a licensing and research collaboration related to ProQR’s proprietary Axiomer RNA base-editing platform. Under the terms of the agreement, ProQR received $50 million upfront consisting of an upfront payment of $20 million, as well as an equity investment of $30 million.

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.
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.
About Usher Syndrome Type 2a and Non-Syndromic Retinitis Pigmentosa (nsRP)
Usher syndrome is the leading cause of combined deafness and blindness. People with Usher syndrome type 2a are usually born with hearing loss and start to have progressive vision loss during adulthood. The vision loss can also occur without hearing loss in a disease called non-syndromic retinitis pigmentosa. Usher syndrome type 2a and non-syndromic retinitis pigmentosa can be caused by mutations in the USH2A gene. To date, there are no pharmaceutical treatments approved or in clinical development that treat the vision loss associated with mutations in USH2A.
Ultevursen (formerly QR-421a) is a first-in-class investigational RNA therapy designed to address the underlying cause of vision loss in Usher syndrome type 2a and non-syndromic retinitis pigmentosa due to mutations in exon 13 of the USH2A gene. QR-421a is designed to restore functional usherin protein by using an exon skipping approach with the aim to stop or reverse vision loss in patients. Ultevursen is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the US and the European Union and received fast-track and rare pediatric disease designations from the FDA.
About Autosomal Dominant Retinitis Pigmentosa (adRP)
Autosomal dominant retinitis pigmentosa, or adRP, is a severe and rare genetic disease that causes progressive problems in night vision during childhood, leading to visual field loss and frequently resulting in blindness in mid adulthood. In the United States, the most prevalent mutation associated with adRP is the P23H point mutation (also known as the c.68C>A mutation) in the rhodopsin (RHO) gene and affects approximately 2,500 people. This mutation causes misfolding of the rhodopsin protein that becomes toxic to the photoreceptor cells and at the same time diminishes the function of the wild type allele. Over time this results in cell death and progressive vision loss. There are currently no therapies approved or in clinical development for P23H adRP. A natural history study in patients with P23H adRP has been conducted.
QR-1123 is a first-in-class investigational RNA therapy designed to treat adRP due to the P23H mutation in the RHO gene. QR-1123 was discovered and developed by Ionis Pharmaceuticals using Ionis’ proprietary antisense technology. The therapy aims to inhibit the formation of the mutated toxic version of the rhodopsin protein by specifically binding the mutated RHO mRNA. Binding of QR-1123 causes allele specific knockdown of the mutant mRNA by a mechanism called RNase H mediated cleavage without affecting the normal RHO mRNA. QR-1123 is intended to be administered through intravitreal injections in the eye. QR-1123 has been granted Orphan Drug designation in the United States and received Fast Track designation from the FDA.
About Fuchs Endothelial Corneal Dystrophy (FECD)
Fuchs endothelial corneal dystrophy (FECD) type 3 is a common genetic disease that leads to progressive degeneration of the corneal endothelium resulting in corneal edema, scarring and vision loss. Blisters on the cornea are a major cause of pain in patients with advanced FECD. Currently there are no treatment options available to stop or slow down FECD and disease management is aimed to reduce symptoms. The only effective therapy for late-stage FECD is corneal transplantation. The availability of donors, risk of rejection, and the inherent risk of such surgeries are some of the limitations of this option. FECD is a common disorder affecting more than 4% of people over the age of 40 in the United States, with similar numbers reported for other parts of the World. Trinucleotide repeat (TNR) expansion mutations in the TCF4 gene are a common cause of FECD. In people of European descent, around 75% of FECD patients have TNR expansions in TCF4.
QR-504a is a first-in-class investigational RNA therapy designed to address the underlying cause of Fuchs endothelial corneal dystrophy (FECD) due to trinucleotide repeat (TNR) expansion mutations in the TCF4 gene. The TNR expansions cause the TCF4 RNA to aggregate in the corneal endothelial cells forming the characteristic nuclear RNA foci and eventually resulting in FECD. QR-504a is designed to target the TNRs in the TCF4 RNA. The aim is to reduce aggregation and the formation of RNA foci to prevent or stop corneal degeneration in patients with FECD. QR-504a is intended to be administered through intravitreal injections in the eye.
About Axiomer® and Trident®
ProQR is pioneering a next-generation RNA technology called Axiomer®, which could potentially yield a new class of medicines for genetic 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. The Axiomer® EONs are designed to recruit an endogenously expressed RNA editing system called ADAR, which can direct the change of an Adenosine (A) to an Inosine (I) in the RNA – an Inosine is translated as a Guanosine (G).
Our TRIDENT® RNA pseudouridylation platform enables the suppression of nonsense mutations and premature stop codons (PTC) that cause human genetic diseases. Since all premature stop codons contain uridine, pseudouridylation of that uridine converts those nonsense codons into sense codons. TRIDENT® technology harnesses endogenously expressed pseudouridylation machinery to guide RNAs to inhibit nonsense mRNA-mediated decay (NMD) in a sequence-specific manner and promote PTC readthrough. The TRIDENT® technology has the potential to be applied in approximately 11% of all genetic mutations.
ProQR Therapeutics is dedicated to changing lives through the creation of transformative RNA therapies for the treatment of severe genetic rare diseases such as Leber congenital amaurosis 10, Usher syndrome and retinitis pigmentosa. Based on our unique proprietary RNA repair platform technologies we are growing our pipeline with patients and loved ones in mind.
