Business Operations and Program Updates

Sepofarsen for Leber congenital amaurosis 10 (LCA10):

● In April, the first patient was dosed in the Phase 2/3 Brighten trial of sepofarsen in LCA10. The primary objective of the Brighten study is to evaluate safety and tolerability of sepofarsen in patients under 8 years of age.

● In April, Nature Medicine published a case study highlighting a patient who is homozygous for the c.2991+1655A>G mutation in CEP290 and was part of a larger cohort in the Phase 1/2 clinical trial of sepofarsen. Improvements were noted in concordant measures of visual function and retinal structure, including visual acuity, light sensitivity, and visual fields.

● In April, an oral presentation was given at the annual meeting of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) reviewing the Phase 1/2 data for sepofarsen. An oral presentation will be given at the Association for Research in Vision and Ophthalmology (ARVO) on May 6, which is an encore presentation of the InSight second treated eye data.

● Upcoming anticipated sepofarsen events:

● Report top-line results from the pivotal Phase 2/3 Illuminate trial in H1 2022. The Illuminate trial completed enrollment in January following randomization of 36 patients aged 8 years or older to receive either sepofarsen at the target registration dose, a low dose, or sham treatment. The primary endpoint for Illuminate is mean change from baseline in best-corrected visual acuity (BCVA) at Month 12.

● Report updated data from the next interim analysis of the Phase 1/2 InSight extension study in H2 2021.

QR-421a for Usher syndrome and non-syndromic retinitis pigmentosa (nsRP):

● In March, the Company reported results from a planned analysis of the Phase 1/2 Stellar trial demonstrating concordant benefit on multiple measures of vision, including visual acuity, visual fields, and the objective measure of optical coherence tomography (OCT) retinal imaging, after a single dose of QR-421a. QR-421a was observed to be well tolerated with no serious adverse events reported.

● Based on the findings from Stellar, the Company plans to advance QR-421a into two pivotal Phase 2/3 trials by year end, pending finalization of the study designs with Regulatory authorities. Each trial could potentially serve as the sole registration trial.

● The “Sirius” trial is a Phase 2/3 study that will focus on advanced patients with baseline BCVA ≤20/40. The primary endpoint in this trial will be BCVA at 18 months, with potential for an earlier interim analysis.

● The “Celeste” trial is a Phase 2/3 study that will focus on early-moderate patients. The primary endpoint in this trial will be based on static perimetry at 18 months, with potential for an earlier interim analysis.

● In April, preclinical data for QR-421a were published in Molecular Therapy.

QR-1123 for autosomal dominant retinitis pigmentosa (adRP):

● ProQR anticipates reporting initial data from the single dose cohorts (n=8) of the Phase 1/2 Aurora trial in 2021.

QR-504a for Fuchs Endothelial Corneal Dystrophy (FECD):

● The Fuchs Focus study is expected to start enrolling patients in Q2 2021. This study will evaluate safety, tolerability, and molecular biomarker(s), i.e., target engagement, in the corneal endothelium following a single intravitreal injection of QR-504a in approximately 10 patients with FECD who are scheduled for corneal transplant with concurrent lens replacement.

● ProQR anticipates reporting initial data from this trial in 2022.

Business updates:

● The Company closed an underwritten public offering of 13,846,154 ordinary shares on April 5, 2021 at a price of $6.50 per share. The closing included the full exercise of underwriters’ option to purchase 2,076,923 additional shares. Gross proceeds totaled approximately $103.5 million.

● In May, Yarrow Biotechnology, Inc., an RTW Investments, LP incubated company, licensed exclusive rights to ProQR’s antisense oligonucleotide technology to develop and commercialize potential therapies for an undisclosed non-ophthalmic target. Under the terms of the agreement, ProQR is eligible to receive up to $115 million of upfront and milestone payments, plus single digit percentage royalties on the net sales of any resulting products during the royalty term. ProQR will also have the right to receive an undisclosed percentage of equity in the form of shares of common stock of Yarrow.

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 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 being evaluated in the pivotal Phase 2/3 Illuminate trial and is a first-in-class investigational RNA therapy designed to address the underlying cause of Leber 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 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 2 and Non-Syndromic Retinitis Pigmentosa

Usher syndrome is the leading cause of combined deafness and blindness. People with Usher syndrome type 2 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 2 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.

About QR-421a

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. QR-421a 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.

About QR-1123

QR-1123 is being evaluated in the Phase 1/2 Aurora trial and 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 was in-licensed from Ionis Pharmaceuticals in 2018. 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.

About QR-504a

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.
