PROQR THERAPEUTICS ANNUAL REPORT 2021 

Message from the CEO 

Dear fellow shareholders, 

As we emerged from the early days of the pandemic and adjusted to our “new normal”, the 

past year brought significant milestones and challenges for ProQR and the communities we 

serve.   

In February 2022, we reported that the Phase 2/3 Illuminate trial of sepofarsen for LCA10 

did not meet the study’s primary endpoint. Following these results, we performed a 

comprehensive post-hoc analysis of the trial and moved decisively to complete a strategic 

review of our business to prioritize our pipeline, restructure the business, and extend the 

Company’s runway, as we stay focused on our commitment to advance RNA therapies for 

diseases with high unmet need.  

Based on this, we identified two core strategic objectives for the business moving forward – 

the prioritization of select genetic eye disease programs and the development of our 
Axiomer® RNA base-editing technology platform across multiple therapeutic areas. 

Post-hoc analyses of the data from the Illuminate trial showed an encouraging efficacy 

signal when comparing the active treatment and sham eyes to their corresponding 

contralateral eyes across multiple endpoints, where the contralateral eye was used as the 

control. These results were more consistent with data we have seen from earlier clinical 

testing of sepofarsen. We plan to meet with both EMA and FDA in Q3 2022 to discuss these 

data and currently plan to continue Illuminate, the Brighten pediatric study, and Insight. 

Our unique Axiomer® platform technology, which is designed to enable the editing of single 

nucleotides in RNA in a highly targeted and specific manner, holds great potential to target 

a wide range of diseases. In September 2021, we entered a global licensing and research 

collaboration with Eli Lilly and Company (Lilly) focused on the discovery, development, and 

commercialization of potential new medicines for genetic disorders of up to five targets 

relating to the liver and nervous system. Under the terms of the agreement, we received 

$50 million upfront from Lilly, and we are eligible to receive up to approximately $1.25 
billion in milestones, as well as royalties on potential product sales. Axiomer® will continue 

to be a priority for the Company going forward – we intend to announce our internal 

development targets in H2 2022, and the platform holds significant further potential for 

strategic transactions. 

We dosed the first patient in the Phase 2/3 Sirius trial of our investigational RNA therapy 

ultevursen (QR-421a) for people with USH2A-mediated retinitis pigmentosa (RP) and Usher 

syndrome. As part of our strategic pipeline prioritization, we plan to focus on a single Phase 

2/3 Sirius trial of ultevursen with the potential addition of an interim/futility analysis in 2023.

Message from the CEO 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Over the past year, we also strengthened our leadership team and scientific advisory board 

with the appointment of several renowned experts in RNA therapeutics and rare disease. 

This included Theresa Heggie joining ProQR as Chief Operating Officer and John 

Maraganore, PhD, being appointed as a Strategic Advisor to the Supervisory Board. 

The unexpected results from the Phase 2/3 Illuminate trial of sepofarsen required us to 

make extremely difficult decisions to position the business to drive long-term growth and 

value. We strongly believe that our recent strategic shift is the right next step to create long-

term value for all our stakeholders. We remain committed to developing RNA therapies for 

patients with high unmet need and I look forward to continued progress with the business 

in the year ahead. 

I want to offer a special thanks to our employees, our scientific and clinical collaborators, 

and our shareholders for their support over the course of another unpredictable year. We 

remain steadfast in our belief in the promise of RNA therapies and will continue to work to 

make a meaningful impact on the lives of the communities that we serve.

Management Board Report 

The Company 

ProQR Therapeutics N.V., or “ProQR” or the “Company”, is dedicated to changing lives through the creation of 

transformative RNA therapies for the treatment of severe genetic rare diseases with a focus on inherited 

retinal diseases such as Leber’s congenital amaurosis 10, Usher syndrome type 2, and autosomal dominant 

retinitis pigmentosa. Based on our unique proprietary RNA platform technologies, we are growing our 

pipeline with patients and loved ones in mind. 

ProQR was founded in 2012 by Daniel de Boer, Gerard Platenburg, the late Henri Termeer and Dinko Valerio. 

Since September 18, 2014, our ordinary shares have been listed on the NASDAQ Global Market under the 

ticker symbol “PRQR”. As of December 31, 2021, we had raised € 420 million in gross proceeds from our 

public offerings of shares and private placements of equity securities, as well as € 40 million in convertible 

debt. In addition, we have received grants, loans and other funding from patient organizations and 

government institutions supporting our programs, including from Foundation Fighting Blindness and the 

Dutch government under the innovation credit program. 

Our legal name is ProQR Therapeutics N.V. and we were incorporated in the Netherlands, on February 21, 

2012. We reorganized from a private company with limited liability to a public company with limited liability 

on September 23, 2014. Our company has its statutory seat in Leiden, the Netherlands. The address of its 

headquarters and registered office is Zernikedreef 9, 2333 CK Leiden, the Netherlands, telephone number 

+31 88 166 7000. Our US office is located at 245 Main Street, Cambridge, MA 02142, USA. The name and 

address of our agent for service in the United States is Smital Shah, 245 Main Street, Cambridge, MA 02142, 

USA.  

We use various trademarks and tradenames, including without limitation “ProQR”, “Axiomer”, “Trident” and 

our corporate logo, that we use in connection with the operation of our business. Other trademarks or trade 

names of third parties referred to or incorporated by reference in this Annual Report are the property of their

relationship with, or endorsement or sponsorship of us, any other companies. 

Operations 

Our strategy focuses on two key pillars: genetic eye disease and our Axiomer RNA base-editing technology 

platform. 

Genetic eye disease 

Inherited retinal diseases, a group of debilitating eye diseases, affecting over five million people in the world, 

is an area of high unmet medical need for which there is only one approved treatment available for only a 

few thousand patients. We believe our RNA platform based on intravitreal delivery may be suitable to repair 

defective RNA in the eye and stop progression or even reverse vision loss associated with the diseases. Our 

clinical pipeline includes sepofarsen, for CEP290-mediated Leber congenital amaurosis 10, or LCA10, and 

ultevursen, for USH2A-mediated Usher syndrome and retinitis pigmentosa. 

 
 
PAGE 9 / 111 
Management Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

RNA editing platform technologies 

Beyond our clinical portfolio, we discovered and developed two novel proprietary RNA editing platform 

technologies, Axiomer and Trident. Since discovering the Axiomer RNA editing technology in 2014, we have 

established a leading IP estate in the ADAR editing space, a first industry partnership, and with its broad 

applicability, we believe the platform has significant further potential.  

In 2021, we entered into a global licensing and research collaboration with Eli Lilly and Company where our 

Axiomer RNA editing platform will be used to progress new drug targets for genetic disorders in the liver and 

nervous system toward clinical development and commercialization. 

We continuously evaluate further opportunities for beneficial collaborations or strategic partnerships to 

efficiently bring our medicines to patients. 

We are also accelerating the development of Axiomer and expanding into areas beyond the eye, including 

initially liver and central nervous system (CNS), which have strong alignment with our RNA oligonucleotide 

delivery approaches.  

Corresponding to these strategic priorities, in April 2022 we suspended our QR-1123 and QR-504a 

development programs, suspended our IRD research, and had a workforce reduction. 

Our RNA Therapies 

Our investigational RNA therapies aim to repair defective RNA to stop or reverse genetic diseases. Genetic 

diseases are caused by mutations in genes in the DNA. The mutation is copied into the RNA that serves as a 

blueprint for protein production. By designing our RNA therapies to repair the specific mutation in the RNA, 

the function of the protein can be restored. This approach allows us to take away the underlying cause of the 

disease without having to make permanent changes to a patient’s DNA. 

Our investigational RNA therapies are single-stranded RNA oligonucleotides chemically modified to enhance 

stability and cellular uptake. Each of our investigational RNA therapies is designed to repair a specific RNA 

mutation and we believe this targeted approach may offer several advantages compared to other therapeutic 

approaches in the treatment of the rare genetic diseases we target. 

Sepofarsen for Leber Congenital Amaurosis 10 

Leber congenital amaurosis (LCA) is the most common genetic cause of childhood blindness, with LCA Type 

10 (LCA10) being one of the most severe forms. People with LCA10 typically become blind within the first few 

 
 
 
 
PAGE 10 / 111 
Management Board Report 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

years of life and currently there are no approved therapies. The most common mutation is c.2991+1655A>G 

(also known as p.Cys998X) in the CEP290 gene. We estimate this mutation occurs in approximately 2,000 

patients in the Western world. 

Sepofarsen (formerly named QR-110) is in development as a potential treatment for patients who have LCA10 

due to the p.Cys998X mutation. Sepofarsen aims to repair the underlying cause in the RNA by splice 

correction. This RNA splice correction allows the production of a normal (wild-type) CEP290 protein which can 

restore vision in patients with LCA10. Sepofarsen is administered through intravitreal injections in the eye.  

A Phase 1/2 clinical trial of sepofarsen in adults and children with LCA10 due to the p.Cys998X mutation has 

been completed. We presented final data from this trial at the Association for Research in Vision and 

Ophthalmology (ARVO) Annual Meeting in 2020, where sepofarsen demonstrated clinical proof-of-concept in 

LCA10 patients as shown by a significant, rapid and sustained improvement in vision in majority of the 

patients.  

In February 2022 we announced that Illuminate, our pivotal Phase 2/3 trial of sepofarsen in CEP290-mediated 

LCA10, did not meet the primary endpoint of Best Corrected Visual Acuity (BCVA) at Month 12 compared to a 

sham procedure control group. Post-hoc analyses showed that the efficacy signal seen with sepofarsen when 

comparing active treatment and sham eyes to their corresponding contralateral eyes across BCVA, full field 

stimulus testing (FST), and other endpoints, including patient reported outcomes (PROs), was more consistent 

with the results seen in earlier findings, where the contralateral eye was used as the control. We plan to meet 

with the EMA and FDA to discuss these data in Q3 2022.  

Data from the Illuminate trial will be presented at the Seventh Annual Retinal Cell and Gene Therapy 

Innovation Summit, April 29, 2022, and the Association for Research in Vision and Ophthalmology (ARVO) 

Annual Meeting, May 1-4, 2022. 

Sepofarsen has been granted orphan drug designation by the FDA and EMA for LCA and received fast track 

designation by the FDA for LCA10. In 2019, we also received PRIME designation from the EMA for LCA due to 

the CEP290 p.Cys998X mutation as well as rare pediatric disease designation from the FDA for LCA10. 

Ultevursen for USH2A-mediated Retinitis Pigmentosa and Usher Syndrome 

Usher syndrome is the leading cause of combined hearing loss and blindness. Patients are usually born with 

moderate to severe hearing loss that may worsen over time. The retinal phenotype, known as retinitis 

pigmentosa, or RP, starts with night blindness followed by progressive loss of peripheral visual fields (tunnel 

vision) until no vision is left. The retinal phenotype can exist without the hearing loss, this disease is called RP. 

Both Usher syndrome and RP can be caused by mutations in the USH2A gene, which encodes a protein called 

usherin. To date, there are no therapies approved or product candidates in clinical development that treat 

the vision loss associated with USH2A mutations. 

We are developing ultevursen (formerly named QR-421a) for patients with USH2A exon 13 mutations. In the 

Western world, approximately 16,000 patients have vision loss due to mutations in exon 13 of the USH2A 

gene. 

Ultevursen is a first-in-class RNA therapy aimed at modulating the RNA that then results in the expression of 

functional usherin protein in the eye to maintain vision. This candidate is intended to be administered by 

intravitreal injections.  

In March 2021, we presented data from a Phase 1/2 clinical trial of ultevursen, named Stellar, in adults with 

Usher syndrome or nsRP due to exon 13 USH2A mutations. Results demonstrated that ultevursen given as a 

 
 
PAGE 11 / 111 
Management Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

single intravitreal injection was observed to be well tolerated with no serious adverse events noted. 

Ultevursen-treated patients responded on endpoints consistent with their disease stage in both advanced 

and early-moderate patient populations, including BCVA and static perimetry, respectively. Concordant 

improvements were also measured in other endpoints assessing retinal structure and function. On the basis 

of these findings, we advanced ultevursen into two sham-controlled Phase 2/3 clinical trials, which dosed the 

first patients in December 2021. The results from the sepofarsen Illuminate trial indicated that in the enrolled 

patient populations, the inter-patient variability was greater than the intra-patient variability. Therefore, we 

believe the sham comparator is likely not the best control and the contralateral eye may be a better 

comparison to reduce inter-patient variability. The ultevursen program will therefore be amended following 

alignment with regulators to a single Phase 2/3 trial, with the potential addition of an interim/futility analysis 

in 2023. 

Ultevursen received orphan drug designation for the treatment of RP from the FDA and EMA. Ultevursen was 

also granted fast track designation for Usher syndrome type 2 and rare pediatric disease designation for RP 

caused by USH2A exon 13 mutations by the FDA. 

Novel RNA Editing Technologies  

Antisense oligonucleotides (AONs) have been used as therapeutics for the last few decades. ProQR has built 

an extensive pipeline of investigational RNA therapies based on the technologies already available. But our 

scientists have gone beyond that and invented entirely new ways of using oligonucleotides for the treatment 
of genetic diseases. Both the Axiomer and Trident RNA editing platforms are novel, proprietary RNA 

technologies invented at ProQR or with our academic collaborators. We have built a broad intellectual 

property estate around these technologies and together with the leading academic experts in the RNA field, 

we continue to advance these technologies. 

Our Axiomer RNA editing technology is designed to enable the editing of specific single nucleotides in RNA. 

The technology is based on editing oligonucleotides, or EONs, designed to recruit endogenous ADAR enzymes 

(Adenosine Deaminases Acting on RNA) to make single adenosine-to-inosine (A-to-I) changes in the RNA in a 

highly specific and targeted manner. This technology could reverse the more than 20,000 G-to-A mutations in 

the human population that cause disease. In vitro and in vivo work indicates that the EONs are generally 

applicable for the correction of mRNA G-to-A mutations. The technology is also designed to make de novo 

changes to protein function and therefore has broad applicability to genetic and non-genetic diseases.  

A global licensing and research collaboration with Eli Lilly and Company focuses on the discovery, 

development, and commercialization of potential new medicines for genetic disorders in the liver and 

nervous system. The companies will use the Axiomer RNA editing platform to progress up to five new drug 

targets toward clinical development and commercialization. Under the terms of the agreement, ProQR 

received $50 million upfront from Lilly, and is eligible to receive up to approximately $1.25 billion in 

milestones, as well as royalties on potential product sales. We believe the platform holds significant further 

potential for strategic transactions. 

Our Trident RNA pseudouridylation platform is designed to enable the suppression of nonsense mutations 

and premature stop codons (PTC) that cause 11% of all human genetic diseases. Since all premature stop 

codons contain uridine, pseudouridylation of that uridine converts those nonsense codons into sense 

codons. The Trident technology harnesses the endogenously expressed pseudouridylation machinery with 

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 genetic diseases caused by PTCs.

Our Strategy 

Key elements of our strategy include: 

• 

Develop RNA therapies for patients in need. Through our patient-focused approach, we work to 

develop best-in-class therapies and to advance the understanding of conditions that we target. As RNA 

therapies have become an established modality, we are translating new applications in a pipeline of 

product candidates for patients suffering from rare diseases. Our focus on genetic eye disease will 

include exploring the development path for selected ophthalmology programs based on comparing 

active treatment and sham eyes to their corresponding contralateral eyes, subject to regulatory 

feedback from EMA and the FDA, whom we intend to meet with in Q3 of 2022. 

• 

Accelerate our RNA-editing technology platform and pipeline. Our novel and proprietary RNA editing 

platform technologies, Axiomer and Trident, are new ways to use oligonucleotides to edit single 

nucleotides in the RNA. We believe the Axiomer technology may be applicable to more than 20,000 

disease-causing mutations and is designed to make de novo changes to protein function and therefore 

has broad applicability to genetic and non-genetic diseases. The Trident RNA editing platform 

technology may be applicable to 11% of all genetic diseases. We intend to use these platforms to 

develop novel therapies for the eye, and to expand into the liver, CNS, and beyond. We continue to 

validate and create value for these platforms by pursuing additional licensing, partnering and other 

strategic relationships outside this core therapeutic area, like our partnership with Lilly. 

Patient Focused Approach 

ProQR is dedicated to developing best-in-class RNA therapies to improve the lives of patients, families and 

communities affected by rare and underserved conditions. In order to achieve this goal, ProQR strives to 

integrate the patient voice into our decision-making throughout the drug development process as we believe 

that a patient focused strategy is crucial to our success. Therefore, our Patient and Medical Community 

Engagement (PMCE) team actively collaborates with and listens to the communities we serve to ensure that 

the patient voice is at the heart of all the work we do here at ProQR. 

A key initiative at driving this patient voice to the heart of the work we do at ProQR is the Global Patient & 

Caregiver Steering Committee. Launched in January 2020, the Steering Committee is a forum for direct 

patient input on a wide range of topics, to ensure ProQR is meeting the needs of individuals we are striving 

for a solution for. 

In 2020 ProQR partnered with Foundation Fighting Blindness in the My Retina Tracker Program, a 

collaborative, open access program providing no-cost genetic testing and genetic counseling for individuals 

living in the United States with a clinical diagnosis of an IRD. Genetic testing is crucial to receiving an accurate 

diagnosis to then move forward with the best care. 

Sepofarsen for Leber Congenital Amaurosis 10 (LCA10) 

LCA Background 

Leber congenital amaurosis (LCA) is the most common genetic cause of blindness in childhood. The 

c.2991+1655A>G mutation (also known as p.Cys998X) in the CEP290 (centrosomal protein of 290 kDa) gene is 

the most prevalent mutation which generally accounts for the most severe disease phenotype (LCA10). This 

mutation leads to significant decrease in CEP290 protein within the photoreceptor cells in the retina. Patients 

affected by this mutation typically lose sight in the first years of life. Clinical features of LCA10 include loss of 

vision, involuntary eye movement or nystagmus, abnormalities of pupil reactions and no detectable 

photoreceptor electrical signals on electroretinography (ERG).

Management Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

LCA Genetics 

More than 20 genes have been associated with the genetic defect that causes LCA. The most common 

mutation is the p.Cys998X in the CEP290 gene causing LCA10. The p.Cys998X mutation is a single nucleotide 

substitution in the CEP290 gene that creates a new splice site, also called a cryptic splice site, between exon 

26 and 27. During the splicing of the pre-mRNA this causes a part of the intron, or pseudoexon, to be 

included in the mRNA. The pseudoexon contains a premature stop codon, thus the mRNA is not translated 

into the full length CEP290 protein. CEP290 protein is involved in the formation and stability of the connecting 

cilium in photoreceptor cells, which facilitates the transport of proteins from the inner segment to the outer 

segment of the cell. When CEP290 is absent, there is a disturbance in normal protein transport to the outer 

segments of the photoreceptor cell, which provokes the shortening of the outer segment and its inability to 

perform its light transducing function. 

LCA Prevalence and Diagnosis 

LCA affects about 15,000 patients in the Western world. Although diagnosis rates vary, our estimations 

indicate the most common p.Cys998X mutation occurs in approximately 2,000 patients in the Western world. 

Patients are initially diagnosed through the presence of clinical symptoms. Nystagmus, rapid involuntary 

movements of the eyes, tends to be the first symptom visible as well as oculo-digital signs comprising eye 

poking, pressing, and rubbing. Vision impairment or blindness becomes obvious as age increases. After an 

ophthalmological examination, LCA is diagnosed. A genetic screening including all known mutations causing 

LCA is performed to confirm the diagnosis and determine the type of LCA in order to give the patient the 

most accurate prognosis possible. 

Approaches for the Treatment of LCA10 

There are currently no treatments approved for patients with p.Cys998X associated LCA10 and disease 

management is currently supportive in nature. The eye is highly suitable for oligonucleotide therapies as it is 

a contained organ with physical cellular barriers. These natural barriers strongly limit the free entry and exit 

of cells and larger molecules in and out of the eye, therefore limiting the systemic exposure of locally 

administered therapies.

Sepofarsen for LCA10, splice correction for p.Cys998X CEP290 mRNA 

Sepofarsen is designed to bind to pre-mRNA and silences the cryptic splice site leading to production of 

normal mRNA. 

Sepofarsen for the Treatment of LCA10 

Sepofarsen is designed to treat LCA10 by splice correction. By binding to the pre-mRNA, sepofarsen aims to 

silence the cryptic splice site caused by the p.Cys998X mutation. The splicing machinery can thus process the 

pre-mRNA correctly resulting in normal mRNA and we expect the production of full-length functional wild-

type CEP290 protein. Sepofarsen is administered by intravitreal injection. 

Sepofarsen received orphan drug designation from the FDA and EMA for the treatment of LCA. Sepofarsen 

was also granted fast track designation for LCA10 and rare pediatric disease designation by the FDA for 

LCA10 and PRIME designation by EMA for the treatment of LCA due to the CEP290 p.Cys998X mutation. 

Clinical Development for Sepofarsen 

In Phase 1/2 testing, sepofarsen was observed to significantly improve vision and the response was durable 

for up to 12 months. Concordant improvements in key secondary outcome measures supported the 

observed change in vision. In the target registration dose group (160µg/80µg) sepofarsen was well-tolerated 

with a favorable benefit/risk profile. Available data from the Phase 1/2 study (PQ-110-001) confirm clinical 

proof-of-concept as shown by the significant improvement in BCVA and is further supported by improvement 

in performance on the mobility course and FST. Importantly, the three endpoints analyzed showed 

concordant improvement, as summarized in Table 1. In approximately 60% of subjects, multiple independent 

measures of visual function were improved in the treated eye, but not in the contralateral eye.

Measurements of BCVA and functional vision (mobility) confirmed vision improvement in these subjects. In 

addition, clear improvement in FST was seen at both red and blue wavelengths in the treated eye only. 

Performance on a mobility course was also improved. Concordant improvement in the mechanistic and 

functional outcome measures support the potential on-target benefits of sepofarsen. 

Phase 1/2 Insight Extension Study 

The ongoing Insight study, or PQ-110-002, is an open-label extension study to evaluate the safety, tolerability, 

efficacy, and pharmacokinetics (PK) of sepofarsen in subjects who completed participation in study PQ-110-

001. Insight will provide continued access to the investigational product in the treated eye, as well as 

treatment of the contralateral eye. In July 2020, preliminary data from the Insight study were presented, which 

showed benefits consistent with the Phase 1/2 findings. We reported additional and updated data from the 

Insight study in November 2021 showing that the vast majority of the treated eyes have demonstrated 

improvement on multiple endpoints. 

Mobility Course Validation Study 

This study is designed to evaluated whether a mobility course using multiple light levels simulating real world 

conditions can detect changes in vision in subjects with a phenotype representative of LCA10. The study was 

conducted at 17 sites across 9 countries, and will include 48 patients in the final analysis that is underway. 

Once finalized, we intend to discuss with Regulators potential validation of this mobility course as an 

endpoint in future studies in IRDs. 

Phase 1/2 Brighten Study 

Brighten is a Phase 2/3 trial of sepofarsen in pediatric patients less than 8 years old. The study started in 2021 

and the primary objectives of the study are safety and tolerability. 

Phase 2/3 Illuminate Pivotal Trial 

Illuminate (PQ-110-003) is a Phase 2/3 pivotal trial that aims at defining safety and quantifying the treatment 

effect, relative to masked, sham-treated control subjects, at more than one dose level (160μg/80µg target 

registration dose level and 80μg/40µg). This study randomized 36 patients aged 8 years or older to receive 

sepofarsen at the target registration dose, a low dose, or sham treatment. Enrollment was completed in 

January 2021. In February 2022, we reported that Illuminate did not meet the primary endpoint of BCVA at 

Month 12 compared to a sham procedure control group.

Phase 2/3 Illuminate post-hoc analyses 

In April 2022 we reported post-hoc analyses of the trial, which showed that the efficacy seen with sepofarsen 

when comparing active treatment and sham eyes to their corresponding contralateral eyes across BCVA, FST, 

and other endpoints, including PROs, is more consistent with the results seen in earlier trials, where the 

contralateral eye was used as the control. The overall safety profile of sepofarsen was consistent with earlier 

trials.  

In figure 1, when the effect in the treatment eye (TE) was compared to the untreated contralateral eye (CE) in 

the same patient, at Month 12, a benefit in vision was observed as a mean change from baseline in BCVA of -

0.12 logMAR (n=23) in the sepofarsen treated groups. This effect was not observed in the sham treated group 

(n=12) with the same comparison (treated vs. contralateral eye).

Based on the recommendation of the DSMC, we plan to continue Illuminate, which is a 2 year study, the 

Brighten pediatric study, and Insight, until further regulatory guidance is obtained, after which next steps will 

be determined.  

We plan to report data from the Illuminate trial at the upcoming Seventh Annual Retinal Cell and Gene

(ARVO) Annual Meeting, May 1-4, 2022. 

Ultevursen for USH2A-mediated Retinitis Pigmentosa and Usher Syndrome 

Usher Syndrome and RP Background 

Usher syndrome is the leading cause of combined inherited deafness and blindness. Patients with this 

syndrome generally progress to a stage in which they have very limited central and peripheral vision and are 

divided in two subgroups: patients with Usher syndrome and patients that have retinitis pigmentosa (RP) due 

to a mutation in the USH2A gene. Patients with Usher syndrome develop vision loss in time, and are usually 

born with moderate to severe hearing loss that may worsen over time, whereas patients with RP develop 

vision loss only. Each subgroup is about 50% of the total population. 

The retinal phenotype known as RP is characterized by photoreceptor degeneration that leads to progressive 

vision loss. The first visual symptoms typically appear during the second decade of life and start with night 

blindness due to the start of degeneration of rod photoreceptors. When rod degeneration progresses, 

patients lose their peripheral visual fields until only a residual central island of vision (tunnel vision) is left. As 

the disease progresses further, cone photoreceptors degenerate which eventually results in complete 

blindness. 

Representation of USH2A Exon 13 Mutations Causing Retinitis Pigmentosa 

Usher Syndrome and RP Genetics 

Usher syndrome and RP can be caused by autosomal recessive mutations in the USH2A gene, encoding the 

protein usherin. Mutations in the USH2A gene can disrupt the production of usherin, a protein expressed in 

photoreceptors where it is required for their maintenance. Usherin is also expressed in the ear, where it is 

required for normal development of cochlear hair cells and hence, normal hearing. In the eye, defects in 

usherin cause RP. Exon 13 mutations represent the most common mutations in the USH2A gene. 

 
 
 
 
PAGE 19 / 111 
Management Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Disease Prevalence and Diagnosis 

The diagnosis of the disease is based on clinical symptoms and ophthalmologic evaluations. A genetic 

screening can determine the specific mutation that is causing the disease. The number of patients with vision 

loss due to USH2A exon 13 mutations is estimated to be around 16,000 in the Western world. Lack of access 

to genotyping may result in significant underdiagnosis in many inherited retinal diseases. 

Approaches for the Treatment of Usher Syndrome and RP 

While the hearing deficit in patients with Usher syndrome type 2 can be at least partially mitigated using 

hearing aids or cochlear implants, there is no approved treatment for the vision loss associated with USH2A 

mutations. Disease management is supportive in nature. We believe that intravitreal RNA therapy ultevursen 

is the only product candidate in pivotal Phase 2/3 development for the treatment of patients with RP caused 

by exon 13 mutations in the USH2A gene. Due to the size of the USH2A gene, this type of RP is not amenable 

to a gene therapy approach. Also, given the disease affects both the peripheral and central retina, current 

gene replacement and gene editing approaches have fundamental limitations as these therapies must be 

delivered with a surgical procedure to a limited subretinal area. The important deficit in peripheral vision of 

USH2A patients is therefore not addressed. 

Ultevursen for the Treatment of Usher Syndrome and RP 

Ultevursen is being developed as a treatment for RP caused by mutations in exon 13 of the USH2A gene. 

Mutations in exon 13, including the prevalent c.2299delG mutation, can disrupt the production of usherin, 

which is required for photoreceptor maintenance. Ultevursen aims to induce excision, or skipping, of exon 13 

from USH2A mRNA leading to an in-frame deletion in the USH2A mRNA. Since exon 13 encodes for a repetitive 

part of the usherin protein, excision of exon 13 is expected to lead to a truncated (partial), however, 

functional usherin protein. Because of the exon skipping approach, ultevursen is not specific to a single 

mutation but targets any mutation present in exon 13 of the USH2A gene. 

USH2A exon 13 exon skip 

Ultevursen received orphan drug designation from the FDA and EMA for the treatment of RP. Ultevursen was 

also granted fast track designation for Usher syndrome type 2 and rare pediatric disease designation for RP 

caused by USH2A exon 13 mutations by the FDA.

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Clinical Development of Ultevursen 

Stellar (PQ-421a-001) was a Phase 1/2 randomized, single ascending dose study designed to evaluate the 

safety and tolerability of ultevursen in subjects with vision loss due to mutations in exon 13 of the USH2A 

gene. The primary objective of the trial was to evaluate safety and tolerability. Secondary objectives included 

evaluating visual acuity (as measured by BCVA), visual fields (as measured by static perimetry and 

microperimetry), and changes in retinal structure (as measured by optical coherence tomography, or OCT). 

The study was conducted at expert sites in North America and Europe. 

The Stellar trial completed enrollment in late 2020. The study included a total of 20 patients, of which 14 

received a single dose of ultevursen and six received a single sham procedure for masking. The 14 treatment 

patients enrolled (mean age of 46 years) varied in their disease stage and were classified as advanced 

patients (defined as patients with baseline visual acuity of <70 letters or equivalent to worse than 20/40 on a 

Snellen chart) or early-moderate patients. Six patients met the criteria for advanced disease and eight 

patients met the criteria for early-moderate disease. Three different dose levels were studied. The population 

also varied in disease characteristics with both Usher syndrome (n=7) and nsRP (n=7) and genetic background 

with both homozygous (n= 9) and heterozygous (n=5) subjects for USH2A exon 13 mutations. All patients were 

followed for up to 48 weeks, with one patient followed up to 96 weeks.  

In March 2021, results from the Stellar trial were reported. 

Safety Data 

Ultevursen was observed to be well tolerated with no serious adverse events reported. Two cases of pre-

existing cataracts were observed, one in the treated eye and one in the untreated eye of the same patient. 

Both are considered not treatment related. Cataracts are known to occur as part of the background disease 

in in over 30% of the patients. No new cataracts were reported in the study. Cystoid macular edema, or CME, 

is frequently associated with the disease and is part of the natural history of the disease in over 30% of the 

patients, and is usually managed adequately with topical eyedrops. One subject with pre-existing CME was 

enrolled into the 200µg cohort. The CME progressed during the study but was classified as mild and managed 

with standard of care therapy. No new cases of CME occurred during the study. 

Efficacy Data 

Due to the different rates of disease progression between patients, the patient’s untreated contralateral eye 

was used as a control. In patients with advanced disease, the primary measure of efficacy is best corrected 

visual acuity, or BCVA. In early-moderate disease patients, the primary measure of efficacy is measurement of 

visual fields by static perimetry. Ultevursen-treated patients responded on endpoints consistent with their 

disease stage in both advanced and early-moderate patient populations. Concordant improvements were 

also measured in other endpoints assessing retinal structure and function.  

As shown in Figure 4, the data established the dosing interval at 6 months with a sustained effect of 

approximately 6 months across multiple endpoints. The 6-month durability of effect is in line with the half-life 

of ultevursen and is the dosing regimen in the Phase 2/3 Sirius trial.

There were no observed differences in responses at the different dose levels or responses between 

homozygotes and heterozygotes as well as usher syndrome and RP patients. 

As shown in figure 5, the advanced population demonstrated a mean benefit of 9.3 letters at the one year 

time point after a single injection. At 72 week follow up, the treatment benefit had further extended to a 

mean 13 letter benefit after a single injection. This served the basis for the Phase 2/3 Sirius study.

Ultevursen treated eyes

Contralateraleyes

Weeks

Phase 2/3 trial of ultevursen 

Regulatory input was obtained on the design of two potentially pivotal trials of ultevursen– Sirius and Celeste. 

The first patients were dosed in these studies in December 2021. 

In April 2022 following the results from the sepofarsen Illuminate trial, which indicated that in the enrolled 

patient population, the inter-patient variability was greater than the intra-patient variability, and therefore the 

sham comparator is likely not the best control and the contralateral eye may be a better comparison to 

reduce variability, the program will be amended to focus on a single Phase 2/3 Sirius trial with the potential 

addition of an interim/futility analysis in 2023. Updates on planned adjustments to the Sirius trial in light of 

the findings related to sham control will be provided after alignment with regulatory authorities, which we 

intend to seek in Q3 2022.

Phase 1/2 Helia extension study 

An open-label treatment extension study, Helia, has begun enrolling eligible participants who have completed 

the Phase 1/2 Stellar trial. Patients will be offered multiple-dose treatments for both eyes. 

Other Pipeline Programs 

In April 2022 we announced a portfolio reprioritization and suspended the development of QR-1123 for 

autosomal dominant retinitis pigmentosa, QR-504a for Fuchs endothelial corneal dystrophy, and our earlier 

stage IRD research programs. 

Axiomer RNA Base-Editing Platform Technology 

With the Axiomer platform we discovered at the ProQR labs, we can harness the endogenous editing system 

in our cells to repair RNA in an entirely new way, by editing oligonucleotides (EONs) that are designed to 

recruit ADAR (Adenosine Deaminases Acting on RNA) enzymes to a selected target RNA where it then 

performs an adenosine-to-iosine (A-to-I) edit. Because an ‘I’ is read by the translation machinery as a 

guanosine (G) this innovative platform has the potential to reverse the 20,000 known disease-causing G-to-A 

mutations. In addition to reversing mutations, the technology also has the ability to make de novo changes to 

protein function by making edits to wild-type RNA, expanding the potential of the platform further to both 

genetic and non-genetic diseases. 

ADAR RNA Editing 

ADAR is an RNA editing system that is present in all human cells which was first discovered in 1987. In the 

human body, ADAR is responsible for editing RNA to, for example, to create different isoforms of proteins, 

change the functionality of small RNA molecules and regulate splicing. A-to-I RNA editing is a very frequently 

occurring natural process. Our platform evolved from the mechanism that nature developed.  

Editing Oligonucleotides 

We created synthetic editing oligonucleotides, or EONs, based on what we saw in nature. It mimics the double 

stranded RNA target sequence that is recognized by endogenous ADAR, which then deaminates the targeted 

‘A’ in the RNA to create an ‘I’. The EONs are short single stranded chemically modified oligonucleotides that 

can be delivered without a vector. A range of chemical modifications at specific regions of the EONs help with 

stability and editing efficiency. For example, backbone modifications of the ADAR-binding region enable ADAR 

binding and improve stability of the EON. Specific modification of the dZ base in the editing enabling region 

has shown to greatly improve editing efficiency.

Lilly partnership 

A global licensing and research collaboration with Eli Lilly and Company focuses on the discovery, 

development, and commercialization of potential new medicines for genetic disorders in the liver and 

nervous system. The companies will use the Axiomer RNA editing platform to progress up to five new drug 

targets toward clinical development and commercialization. Under the terms of the agreement, ProQR 

received $50 million upfront from Lilly, and is eligible to receive up to approximately $1.25 billion in 

milestones, as well as royalties on potential product sales. We believe the platform holds significant further 

potential for strategic transactions. 

Axiomer Platform for the Treatment of Genetic Conditions 

The Axiomer platform technology has broad applicability with the potential to address a wide range of 

currently untreatable diseases. We have optimized our design rules and can now apply these across targets 

which cause diseases in multiple different organs. Our focus will be on developing the platform for conditions 

of the eye, liver and central nervous system. We have achieved editing efficiencies of approximately 60% in 

cells and up to 20% editing in our human retinal organoid model. We are accelerating this work and will be 

selecting our internal development candidates and provide further pipeline guidance during the second half 

of 2022. 

Intellectual property 

With a portfolio of 11 patient families and one additional pending, the broad Axiomer® patent estate protects 

key features of EON design and ADAR recruitment. The estate protects different designs of ADAR recruiting 

editing oligonucleotides (EONs), recruitment of both ADAR1 and ADAR2, unmodified and chemically modified 

EONs and stereopure EON designs. The patents date back to 2014, protecting the platform beyond 2040. 

Human Resources 

We believe in passion and commitment and have built a strong team of ProQRians from all walks of life and 

approximately 35 different nationalities, who are up to the challenge and committed to make a difference for 

the patients we serve. We actively create a caring atmosphere, in which we love to work and maintain 

productive and happy lives. At ProQR we foster empowerment, self-development, creativity, and a sense of 

community. 

As an employer, we are a true believer in the value of a workforce in which people from diverse backgrounds 

are encouraged to develop themselves both personally and professionally. This is reflected in our equal 

gender balanced leadership team and broader workforce. We believe that happy and energized people, 

working well together in an environment in which they thrive, will do phenomenal and awesome things. 

We are committed to ensure that no employee, candidate, or job applicant receives less favorable treatment 

on the grounds of race, age, disability, pregnancy, religion, gender identity and expression, sexual orientation, 

marriage or civil partnership status. At ProQR we want to create an inclusive culture where everyone can be 

valued for who they are and in which individual differences and the contributions in all forms are recognized 

and valued. 

Animal Welfare 

It is required by regulatory authorities to demonstrate the safety and, if possible, efficacy of a new drug in 

animals before it can be tested in humans. The welfare of animals in our preclinical studies is of great 

importance to ProQR for reasons of ethics, quality, reliability, and applicability of scientific studies. To assure 

high quality (scientific) research, animal welfare is essential. By actively pursuing the 3R principles (Reduce, 

Refine and Replace), ProQR is committed to reduce the number of animals needed, minimize discomfort and 

pain of animals used, and use alternatives to animal research whenever possible. 

 
 
 
PAGE 24 / 111 
Management Board Report 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

Animal experiments will be performed only if there are no alternatives such as performing in silico, in-vitro or 

ex-vivo studies. Study designs will be evaluated with the aim to identify opportunities to reduce the number 

of animals needed to achieve the objectives of the study. By conducting small pilot (tolerability) studies and 

by using innovative new technologies and modeling approaches, ProQR further pursues the ambition to 

reduce, refine and replace animal studies. Approval by the (institutional or national) animal care and use 

committees is required prior the execution of in vivo studies. 

External collaborators contracted for the execution of our in vivo preclinical studies, also known as contract 

research organizations (CROs), are selected based on their expertise, quality and accreditations for laboratory 

animal care and welfare. CRO facilities are audited by ProQR prior to contracting to ensure that the housing, 

husbandry and welfare of animals complies with the highest international standards. Personnel responsible 

for housing, husbandry and the care of animals must have received adequate and relevant documented 

education. 

Manufacturing and Supply 

We do not currently own or operate manufacturing facilities to produce clinical or commercial quantities of 

any of our product candidates. We currently contract with drug product manufacturers for the production of 

sepofarsen solution for intravitreal injection and ultevursen solution for intravitreal injection, and we expect 

to continue to do so to meet the planned clinical requirements of our product candidates. 

Currently, each of the active ingredients for our manufacturing activities are supplied by single source 

suppliers. We have agreements for the supply of such active ingredients with manufacturers that we believe 

have sufficient capacity to meet our demands. In addition, we believe that adequate alternative sources for 

such supplies exist. We typically order clinical supplies and services on a purchase order basis and do not 

enter into long-term dedicated capacity or minimum supply arrangements. We have a commercial supply 

agreement in place for the manufacturing of the active ingredient in sepofarsen. This agreement took effect 

in July 2019 to cover the process qualification activities, and will remain effective until ten years after the date 

of first commercial sale of sepofarsen. The agreement may be terminated earlier by either party in case of a 

material breach of the agreement, or by us in case (i) the product or the development thereof is discontinued, 

(ii) of insufficient supplies of the product, or (iii) of a refusal to implement changes required by regulatory 

authorities. During the first five years after the first commercial sale, we shall be required to exclusively order 

our demand of sepofarsen under this agreement, and thereafter only half the demand. Every half year, we 

shall submit 36 months forecasts of which the first 12 months are a binding take or pay commitment. 

Manufacturing is subject to extensive regulations that impose various procedural and documentation 

requirements, which govern record keeping, manufacturing processes and controls, personnel, quality 

control and quality assurance, amongst others. The contract manufacturing organizations we use 

manufacture our product candidates under cGMP conditions. cGMP is a regulatory standard for the 

production of pharmaceuticals that will be used in humans. 

Competition 

The pharmaceutical industry is highly competitive and subject to rapid and significant technological change. 

Our potential competitors include large pharmaceutical, biotechnology, specialty pharmaceutical, and generic 

drug companies, academic institutions, government agencies and research institutions. Key competitive 

factors affecting the commercial success of our product candidates are likely to be efficacy, safety and 

tolerability profile, delivery, reliability, convenience of dosing, patient recruitment for clinical studies, price 

and reimbursement. Many of our existing or potential competitors have substantially greater financial, 

technical, and human resources than we do and significantly greater experience in the discovery and 

development of product candidates, obtaining FDA, EMA and other regulatory approvals of products and the 

commercialization of those products. Mergers and acquisitions in the pharmaceutical and biotechnology 

 
 
PAGE 25 / 111 
Management Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

industries may result in even more resources being concentrated among a small number of our competitors. 

Accordingly, our competitors may be more successful than we may be in obtaining FDA or EMA approval for 

therapies and achieving widespread market acceptance. Our competitors’ products may be more effective, or 

more effectively marketed and sold, than any product candidate we may commercialize and may render our 

therapies obsolete or non-competitive before we can recover development and commercialization expenses. 

Our competitors are working on similar technologies in the field of RNA repair and RNA editing, but also in 

the field of gene editing and gene therapy as well as other types of therapies, such as small molecules, 

protein replacement or antibodies. The industry targeting hereditary ophthalmology indications is driven by 

gene therapy, gene editing, and other approaches. 

Main financial developments 

Financial position 

In 2021, our operating costs increased compared to last year while our liquidity improved and our solvency 

slightly decreased. At December 31, 2021, ProQR’s cash and cash equivalents amounted to € 187,254,000 

compared to € 75,838,000 at December 31, 2020. During the year 2021, cash used in operating activities 

amounted to € 26,012,000, compared to € 47,060,000 in 2020. Total equity increased to € 113,229,000.  

As at December 31, 2021, we had borrowings of € 44,090,000, which consisted of convertible loans and 

borrowings from a government body. Based on the current state of affairs and existing funding, taking into 

account our current cash position and projected cash flows, it is justified that the financial statements are 

prepared on a going concern basis. 

Income statement 

We have generated losses since our formation in February 2012. For the years ended December 31, 2021 and 

2020, we incurred net losses of € 61,680,000 and € 46,614,000, respectively. As at December 31, 2021, we had 

an accumulated deficit of € 317,770,000. We expect to continue incurring losses for the foreseeable future as 

we continue our pre-clinical studies of our product candidates, continue clinical development of our product 

candidates including sepofarsen, ultevursen, QR-1123 and QR-504a, increase investments in our other 

research programs, apply for marketing approval of our product candidates and, if approved, build a sales 

and marketing infrastructure for the commercialization of our product candidates. To date, we have not 

generated any revenues from royalties or product sales. Based on our current plans, we do not expect to 

generate royalty or product revenues for the foreseeable future. 

In 2021, revenues amounted to € 1,354,000 (2020: nil), consisting principally of non-refundable upfront fees 

and research and development service fees in connection with collaboration and license agreements. In 2021, 

other income amounted to € 1,043,000 compared to € 9,452,000 in 2020. In 2020 ProQR received a final 

waiver of the full amount of the Innovation credit for the Company’s cystic fibrosis program. Consequently, 

other income included a gain of € 8,423,000 relating to this waiver. In 2021 and 2020, other income also 

included grant income from the Foundation Fighting Blindness (FFB) for the purpose of developing QR-421a. 

FFB grant income amounted to € 977,000 in 2021 compared to € 624,000  in 2020. 

Research and development costs increased to € 42,220,000 in 2021 compared to € 38,135,000 in 2020. 

Research and development costs comprise allocated employee costs including share-based payments, the 

costs of materials and laboratory consumables, the costs for production of clinical and pre-clinical 

compounds and outsourced activities, costs related to our preclinical and clinical activities and trials, license 

and intellectual property costs and other costs. These costs were primarily related to our product candidates 

sepofarsen and ultevursen, and our innovation unit, which includes the Axiomer platform. Our research and 

development expenses are highly dependent on the development phases of our product candidates and are 

expected to stay at the same level, although they may fluctuate significantly from period to period. 

 
 
 
PAGE 26 / 111 
Management Board Report 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

The increase in research and development costs in the year ended December 31, 2021 compared to the year 

ended December 31, 2020 is mainly due to: 

• 
• 

• 

• 

costs we incurred for the Phase 2/3 clinical trials for ultevursen, which commenced in 2021; 

costs we incurred for the Phase 2/3 clinical trial for sepofarsen, which increased in 2021 compared to 

2020, when the related costs were lower due to delays caused by the COVID-19 pandemic; 

higher employee benefits (excluding share-based compensation) resulting from an increase in the 

average number of research and development staff in 2021 compared to 2020; 

the above effects are partly offset by decreased share-based compensation, reflecting grants of share 

options to research and development staff. 

General and administrative costs amount to € 17,368,000 in 2021 compared € 13,685,000 in 2020. These 

general and administrative costs comprise employee costs including share-based payments, office & IT costs, 

general consultancy costs and other costs. As a public company, we face increased legal, accounting, 

administrative and other costs and expenses.  

The increase in general and administrative costs in the year ended December 31, 2021 compared to the year 

ended December 31, 2020 is mainly due to: 

• 

• 

• 
• 

higher employee benefits (excluding share-based compensation) resulting from an increase in the 

average number of general and administrative staff in 2021 compared to 2020;  

the above effects are partly offset by decreased share-based compensation, reflecting grants of share 

options to general and administrative staff; 

costs we incurred for preparing for potential future commercialization of our product candidates. 

increased costs for our Directors & Officers (D&O) insurance. 

In 2021 share-based compensation amounted to € 6,216,000, compared to € 7,838,000 in 2020. Net financial 

expenses amounted to € 2,789,000, compared to € 3,716,000 in 2020. Financial expenses consist principally 

of fixed-rate interest expenses on convertible loans. Financial income and expenses also include foreign 

exchange differences on cash and loan balances denominated in U.S. dollars and can fluctuate significantly. 

The Company operates a foreign exchange policy to manage the foreign exchange risk against the functional 

currency based on the Company’s cash balances and the projected future spend per major currency. 

Outlook 

We expect to continue to spend substantial amounts of cash to conduct further research and development 

and preclinical testing and clinical trials of our product candidates and to seek regulatory approvals for our 

product candidates. Based on our current operating plans announced as part of our strategy update in April 

2022, we believe that the existing cash and cash equivalents will be sufficient to fund our anticipated level of 

operations into 2025. Given the development stage of the Company, we do not anticipate revenues from 

product sales in the foreseeable future. 

Risks of fraud and non-compliance with laws and regulations 

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include 

intentional failures to comply with FDA or EMA regulations or similar regulations of other foreign regulatory 

authorities, to provide accurate information to the FDA, the EMA or other foreign regulatory authorities, to 

comply with certain manufacturing standards, to comply with U.S. federal and state healthcare fraud and 

abuse laws and regulations and similar laws and regulations established and enforced by comparable foreign 

regulatory authorities, to report financial information or data accurately or to disclose unauthorized activities 

to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to 

extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. 

 
 
PAGE 27 / 111 
Management Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and 

promotion, sales commission, customer incentive programs and other business arrangements. Employee 

misconduct could also involve the improper use of information obtained in the course of clinical trials, which 

could result in regulatory sanctions and serious harm to our reputation. We have adopted and implemented 

a Code of Business Conduct and Ethics, but it is not always possible to identify and deter employee 

misconduct, and the precautions we take to detect and prevent this activity, such as employee training on 

enforcement of the Code of Business Conduct and Ethics, may not be effective in controlling unknown or 

unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits 

stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted 

against us, and we are not successful in defending ourselves or asserting our rights, those actions and any 

imposition of significant fines or other sanctions could have a significant impact on our business and results 

of operations. 

We monitor and assess applicable Dutch and U.S. federal and state corporate governance codes, rules, and 

regulations. We apply the 2016 Dutch Corporate Governance Code (the “Code”). We also are required to 

comply with all applicable U.S. securities laws and regulations, including the rules and regulations 

promulgated by the SEC pursuant to the U.S. Exchange Act of 1934 and the U.S. Sarbanes-Oxley Act of 2002, 

as well as the U.S. Nasdaq Global Select Market (“Nasdaq”) listing rules. 

Our corporate governance structure is based on the requirements of the Dutch Civil Code, the company’s 

Articles of Association and the rules and regulations applicable to companies listed on the Nasdaq. These 

procedures include a risk management and control system, as well as a system of assurance of compliance 

with laws and regulations. 

The effects of the ongoing COVID-19 pandemic materially and adversely affect our business and our 

financial results 

The continued effects of the COVID-19 pandemic could adversely impact our clinical trials or preclinical 

studies, including our ability to recruit and retain patients and principal investigators and site staff who, as 

healthcare providers, have heightened exposure to COVID-19. For instance, the COVID-19 pandemic has 

resulted in the delays of all of our ongoing and scheduled trials, including our ongoing pivotal trial of 

sepofarsen for LCA10 and the ongoing pivotal trials of ultevursen for Usher syndrome. While we have 

implemented mitigation procedures designed to enable us to continueresume  our development activities 

when the disruption resolves, there can be no assurance that these procedures will continue to be successful 

or that we can avoid a material and adverse disruption to our business in case a further spikes in the number 

of infections would occur in countries where patients are expected to be enrolled or where they are located. 

As the pandemic continues, we have experienced the prioritization of hospital resources toward the 

treatment of COVID-19 patients and restrictions in travel. Furthermore, persons living with indications that 

are targeted by ProQR’s product candidates may be unwilling to enroll in our trials or be unable to comply 

with clinical trial protocols if quarantines or travel restrictions continue to impede patient movement or 

interrupt healthcare services. COVID-19 also negatively affects the operations of third-party contract research 

organizations (CROs) that we rely upon to carry out our clinical trials. Moreover, COVID-19 might impact the 

operations of our third-party manufacturers, which could result in delays or disruptions in the supply of our 

product candidates. Three Since the beginning of the COVID-19 pandemic, three vaccines for COVID-19 were 

grantedhave received Emergency Use Authorization by the FDA in late 2020 and early 2021and two of these 

later received marketing approval., and more are likely to be Additional vaccines may be authorized or 

approved in the coming monthsfuture. The resultant demand for vaccines and potential for manufacturing 

facilities and materials to be commandeered under the Defense Production Act of 1950, or equivalent foreign 

legislation, may make it more difficult to obtain materials or manufacturing slots for the products needed for 

our clinical trials, which could lead to delays in these trials. While we do not currently believe our supply chain 

has been affected, there can be no assurances that we will not experience supply disruptions in the future. 

 
 
 
PAGE 28 / 111 
Management Board Report 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

The negative impact COVID-19 has had and may continue to have to patient enrollment or treatment or the 

timing and execution of our clinical trials could cause costly delays to our clinical trial activities, which could 

adversely affect our ability to obtain regulatory approval for and to commercialize our product candidates, 

increase our operating expenses and have a material adverse effect on our business and financial results.  

In addition, COVID-19 has resulted in significant governmental measures being implemented to control the 

spread of the virus, including quarantines, travel restrictions and business shutdowns. We have taken and 

may continue to take temporary precautionary measures intended to help minimize the risk of the virus to 

our employees, including requiring most of our employees to work remotely, suspending all non-essential 

travel worldwide for our employees and attending industry events and in-person work-related meetings 

remotely. These measures could negatively affect our business. For instance, requiring employees to work 

remotely may result in decreased efficiency and effectiveness of our operations and increases the risk of a 

cybersecurity incident. COVID-19 has also caused volatility in the global financial markets and threatened a 

slowdown in the global economy, which may negatively affect our ability to raise additional capital on 

attractive terms or at all.  

The extent to which COVID-19 continues to impact our business, results of operations and financial condition 

will depend on future developments, which are highly uncertain and cannot be predicted with confidence, 

such as the duration of any ongoing governmental measures and local lockdowns across the world, the 

potential occurrence of future spikes in the spreadthe outbreak, new information that may emerge 

concerning the severity of COVID-19, new strains of the virus, including the Delta and Omicron variants and 

any future variants, or thethat may emerge, which may impact rates of infection and vaccination efforts, 

developments or perceptions regarding the safety of vaccines, or the extent and effectiveness of actions to 

contain and treat for COVID-19 and treat its impact, including vaccination campaigns and lockdown 

measures, among others. In addition, recurrences or additional waves of COVID-19 cases could cause other 

widespread or more severe impacts depending on where infection rates are highestincluding the speed and 

effectiveness of vaccine development and vaccination programs globally. We cannot presently predict the 

scope and severity of any potential business shutdowns or disruptions, but if in case of potential future 

waves of increased infections, if any. If we or any of the third parties with whom we engage, however, were to 

experience prolonged business shutdowns or other business disruptions, our ability to conduct our business 

in the manner and on the timelines presently planned could be materially and negatively affected, which 

could have a material adverse impact on our business, and our results of operation and financial condition.

Supervisory Board Report 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Supervisory Board Report 

ProQR Therapeutics has chosen a so-called two-tier system for its governance structure. In such a structure, 

the Supervisory Board supervises and advises the Management Board in performing their management tasks 

and setting the strategy of the Company. The Supervisory Board as well as its individual members act in the 

interests of the Company. 

During the 2021 financial year, the Supervisory Board and its sub-committees held frequent and productive 

interactions with the Management Board. Where required by ProQR’s articles of association, shareholder 

approvals or Dutch law, Management Board decision making was approved or endorsed by the Supervisory 

Board and matters of both short-term as well as long-term strategic importance were discussed in a 

constructive and transparent manner. Below is a more specific description of the Supervisory Board’s 

activities during 2021 and other relevant information on its functioning. 

Activities of the Supervisory Board 

The Supervisory Board and the Management Board held four video conference meetings in 2021.  During 

these meetings, the progress of the various projects, the main risks of the business, the funding and the 

strategic direction of the Company were discussed. The meetings were well attended with all meetings having 

an attendance rate of 100%. In addition, there were various informal meetings between the Supervisory 

Board and the Management Board during the course of 2021. In addition, the committees reported back on 

their activities to the full Supervisory Board on a regular basis. 

Committees of the Supervisory Board 

During 2021, the Supervisory Board had an audit committee, a compensation, nominating and corporate 

governance committee and a research and development committee, each of which has an adopted charter.  

Compensation, Nominating and Corporate Governance Committee 

The Compensation, Nominating and Corporate Governance Committee (the “Compensation Committee”) met 

five times in 2021. The meetings had an attendance rate of 100%. 

Compensation matters 

Attraction and retention of world class talent is a prerequisite for the success of ProQR and competitive 

compensation plays a vital role in our ability to achieve this. The Compensation Committee elected to offer 

compensation for all employees, including the Management Board in the form of a fixed annual salary 

combined with variable, performance related, short- and long-term incentive elements. The Compensation 

Policy is designed based on the following principles: 

• 

Three compensation pillars consisting of: 

• 
• 
• 

Annual Base Salary; 

Short Term Incentive (annual cash bonus); and 

Long Term Incentive (share-based compensation plan). 

• 

• 

Flexibility: The Compensation Policy should provide flexibility to allow the Supervisory Board, acting on 

the recommendation of the Compensation Committee, to reward the Management Board in a fair and 

equitable manner; 

The Compensation Policy should drive the right kind of management behavior, discourage unjustified 

risk taking and minimize any gaming opportunity;

• 

•

• 

The Compensation Policy should pay for performance, considering not only the measurable financial 

performance of / or milestones achieved by the Company, but also, where appropriate, the efforts 

made by the Management Board, individually and as a group, in managing the Company. For the 

variable components, the Compensation Committee performs an analysis of the possible outcomes 

under different scenarios; 

Design of the Compensation Policy shall be based on current legislation applicable in the Netherlands; 

The Compensation Policy shall foster alignment of interests with shareholders;  

The pension of the Management Board shall be based on the defined contribution system; and 

Pay differentials and position within the Company are considered and evaluated regularly.  

Compensation report 2021 

In line with the practice of regularly reviewing the Compensation Policy, the Compensation Committee 

evaluated and reviewed the Compensation Policy in 2021. Based on the outcomes of the review no changes 

were made to the Compensation Policy for the Management Board. 

The following summarizes the decisions made with respect to the Management Board’s 2021 compensation:    

Annual Base Salary 

The Compensation Committee reviewed the annual base salary of the Management Board taking into 

consideration the Compensation Reference Group as contained in the Compensation Policy. Based on this 

review the annual base salary level for 2021 has been set at € 436,000 for the CEO, Daniel de Boer.  

Short Term Incentive  

The Compensation Committee reviewed the performance of the Company during 2021 in comparison to the 

objectives and reviewed the achievements of the Management Board versus the corporate goals. Based on 

the recommendation of the Compensation Committee, the Supervisory Board decided in late 2021 that the 

Company has achieved 130% of the objectives that had been set to determine the bonus awards for the year 

2021. For 2021 the individual bonus has been set at € 284,000 for Daniel de Boer. This bonus was paid in cash 

in the first quarter of 2022.  

Long Term Incentive 

Based on the recommendation of the Compensation Committee, the Supervisory Board decided to grant 

stock options to Daniel de Boer. Based on this decision, in 2021 stock options with an exercise price of € 3.42 

have been granted to Daniel de Boer with respect to 442,279 shares.  

Pensions 

The pension contributions for Daniel de Boer paid during 2021 amount to € 10,000. 

Internal pay ratio 

The internal pay ratio between the average pay of our employees and our Management Board is calculated 

based on the average remuneration based on short term and long-term incentives. The pay ratio is 15:1 for 

2021 (2020: 19:1). 

Supervisory Board remuneration 

For 2021, members of our Supervisory Board received board fees of USD 35,000 per year and the 

chairperson received a fee of USD 70,000 per year. In addition, audit committee members received a fee of 

USD 7,500 and the audit committee chairperson received a fee of USD 15,000 per year; compensation, 

nominating and corporate governance committee members received a fee of USD 5,000 and the chairperson 

of this committee received a fee of USD 10,000 per year, and; research and development committee 

members received a fee of USD 5,000 and the chairperson of the research and development committee

received a fee of USD 10,000 per year. Further, Supervisory Board members were granted options or 

USD 77,500 in cash, as set out in Note 27 to the financial statements. 

Nominating and Corporate Governance Matters 

With respect to nominating and corporate governance matters, the Compensation Committee assists our 

Supervisory Board in selecting individuals qualified to become our Supervisory Board members and 

management board members, in determining the composition of the management board, supervisory board 

and its committees and our officers in developing and recommending a set of corporate governance 

guidelines applicable to ProQR. In furtherance of this, the Compensation Commiteee is responsible for 

recommending to the Supervisory Board persons to be nominated for election or re-election to the 

Supervisory Board and the management board at any meeting of the shareholders; overseeing the 

Supervisory Board’s annual review of its own performance and the performance of its committees; and 

considering, preparing and recommending to the Supervisory Board a set of corporate governance 

guidelines. 

Research and Development Committee 

The research and development committee met twice in 2021. The meetings had an attendance rate of 100%. 

The research and development committee assists the supervisory board in overseeing our product pipeline 

and research and development strategy. The research and development committee is responsible for, among 

other things, reviewing ProQR’s research and development strategy, including the long-term strategy goals 

and objectives; reviewing and assessing quality of the research and development programs; reviewing the 

progress of the product pipeline, including a review and analysis of the progress and results of pre-clinical 

studies and clinical trials; reviewing and advising the management board about strategic opportunities to 

enhance innovation and development; reviewing and assessing scientific activities critical to the success of 

ProQR’s research and development strategy; and organizing and chairing meetings with ProQR’s scientific 

advisory board for supporting its review and assessment ProQR’s research and development strategy. 

Audit Committee 

The audit committee met five times in 2021. The meetings had an attendance rate of 93%. The main topics 

that were addressed include the quarterly results, financial risk management, compliance (including SOx) , 

the audit plan and management letter of the current external auditor, the transition to a new external 

auditor, cash management, tax and corporate governance. 

The audit committee also reviewed ProQR’s annual financial statements, including non-financial information, 

prior to publication thereof. The financial statements for 2021 have been audited and provided with an 

unqualified opinion by our external auditor, KPMG Accountants N.V. (KPMG), and were extensively discussed 

with the auditors in the meetings of the Supervisory Board, Audit Committee and Management Board on 

April 29, 2022. The Supervisory Board is of the opinion that the 2021 Financial Statements meet all the 

applicable requirements and recommends that the Annual General Meeting of Shareholders adopt the 

financial statements and the appropriation of net result proposed by the Management Board. 

The Company’s external auditor attended all Audit Committee meetings. The Audit Committee evaluates the 

performance of KPMG as independent external auditor annually. Due to the limited size of the Company, it 

was concluded that there was currently no need to appoint an internal auditor.  

The Supervisory Board is responsible for the quality of its own performance and it discusses, once a year on 

its own, without the Management Board present, both its own functioning and that of the individual 

members, and the functioning of the Management Board. The Supervisory Board discussed its functioning 

and competencies and concluded that its functioning and competencies are appropriate for the current 

phase of the company. The Supervisory Board continues to assess its composition and functioning on an

PROQR THERAPEUTICS ANNUAL REPORT 2021 

ongoing basis with the aim to ensure and maintain the requisite expertise, experience and diversity. The 

performance and composition of the Management Board were also found to be adequate. We feel the 

additional efforts of all staff at ProQR form a strong foundation for the success and growth of the Company 

and all milestones reached this past year. Therefore, we would like to express our thanks to the Management 

Board, senior management and all other employees for their contribution and performance during the year. 

We thank our shareholders for their continued support.

Corporate Governance 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Corporate Governance 

ProQR values the importance of complying with Corporate Governance regulations. At the same time, the 

Board of Directors is of the opinion that certain deviations from the provisions of the Dutch Corporate 

Governance Code 2016 (“DCGC” or “the Code”) are justified, in view of our activities, our size and the specific 

circumstances in which we operate. In such cases, which are mentioned in this corporate governance 

statement, we apply the “comply or explain” principle.  

Deviations from certain aspects of the Code, when deemed necessary in the interests of the Company, will be 

disclosed in the Annual Report. Most deviations are justified due to our Company being listed in the United 

States with most of our investors being outside of the Netherlands, as well as to the international business 

focus of our Company. As a Company listed on NASDAQ, we comply with NASDAQ’s corporate governance 

listing standards, except for instances where we follow our home country’s corporate governance practices in 

lieu of certain NASDAQ’s standards as explained below, as NASDAQ investors are more familiar with 

NASDAQ’s rules than with the Code. 

In this report, the Company addresses its overall corporate governance structure and states to what extent 

and how it applies the principles and best practice provisions of the Code. This report also includes the 

information which the Company is required to disclose pursuant to the Dutch governmental decree on Article 

10 Takeover Directive and the governmental decree on Corporate Governance.  

Substantial changes in the Company’s corporate governance structure and in the Company’s compliance with 

the DCGC, if any, will be submitted to the General Meeting of Shareholders for discussion under a separate 

agenda item. The Supervisory Board and the Management Board, which are responsible for the corporate 

governance structure of the Company, are of the opinion that the principles and best practice provisions of 

the DCGC that are addressed to the Management Board and the Supervisory Board, interpreted and 

implemented in line with the best practices followed by the Company, are being applied.  

The full text of the DCGC can be found at the website of the Monitoring Commission Corporate Governance 

Code (www.mccg.nl) and for an overview of our conformity with the Code the following documents are 

available at our website (www.ProQR.com): audit committee charter, compensation committee charter, 

nominating and corporate governance committee charter and our code of business conduct and ethics. 

Management Board 

ProQR is dedicated to improve the lives of patients and their loved ones through the development of RNA 

therapies for severe genetic rare diseases. ProQR has a focus on patients with inherited retinal diseases. The 

expectations and interests of our stakeholders is a key reference point in establishing our long term strategy. 

The Management Board’s role is to develop long term value creation by means of a strategy to pursue the 

long term success of ProQR. The strategy contains multiple elements linked to the Corporate Governance 

Code:  

• 
• 
• 
• 
• 
• 

Implementation and feasibility; 

Business model applied by the company; 

Opportunities and risks; 

Operational and financial objectives; 

Interest of shareholders; 

Any other relevant aspects such as environment, charity and patient organizations. 

 
 
 
PAGE 34 / 111 
Corporate Governance 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

The Management Board executes the strategy by assuming the authority and responsibilities assigned to it by 

Dutch corporate law and by combining expertise and experience with entrepreneurial leadership. The 

Management Board operates under the supervision of the Supervisory Board. The Management Board is 

required to:  

• 

• 
• 

Keep the Supervisory Board informed in a timely manner in order to allow the Supervisory Board to 

carry out its responsibilities;  

Consult with the Supervisory Board on important matters; and  

Submit important decisions to the Supervisory Board for its approval.  

Our Management Board may perform all acts necessary or useful for achieving our corporate purposes, 

other than those acts that are prohibited by law or by our articles of association. The Management Board as a 

whole and any Management Board member individually, are authorized to represent us in dealings with third 

parties.  

Under our articles of association, the number of Management Board members is determined by the 

Supervisory Board, and the Management Board must consist of at least one member. The Supervisory Board 

elects a CEO from among the members of the Management Board.  

Members of the Management Board are appointed by the general meeting of shareholders upon a binding 

nomination of the Supervisory Board. Our general meeting of shareholders may at all times deprive such a 

nomination of its binding character by a resolution passed by at least two-thirds of the votes cast 

representing more than 50% of our issued share capital, following which our Supervisory Board shall draw up 

a new binding nomination.  

Our Management Board rules provide that, unless the resolution appointing a Management Board member 

provides otherwise, members of our Management Board will serve for a maximum term of four years. Our 

articles of association provide that the Management Board members must retire periodically in accordance 

with a rotation schedule adopted by the Management Board. A Management Board member who retires in 

accordance with the rotation schedule may be reappointed immediately for a term of not more than four 

years at a time.  

Our management board currently consists of the CEO, Daniel de Boer. The CEO is supported by a 

management team consisting of the Chief Innovation Officer, the Chief Business and Financial Officer, the 

Chief Medical Officer, the Chief Scientific Officer and the Chief Operating Officer. The supervisory board 

monitors the composition of the management board and management team on an ongoing basis to ensure 

the requisite expertise, experience and diversity is maintained. 

Supervisory Board  

Our Supervisory Board is responsible for the supervision of the activities of our Management Board and our 

Company’s general affairs and business. Our Supervisory Board may, also on its own initiative, provide the 

Management Board with advice and may request any information from the Management Board that it deems 

appropriate. In performing its duties, the Supervisory Board is required to act in the interests of our Company 

(including its stakeholders) and its associated business as a whole. The members of the Supervisory Board 

are not authorized to represent us in dealings with third parties.  

Pursuant to Dutch law, members of the Supervisory Board must be natural persons. Under our articles of 

association, the number of Supervisory Board members is determined by our Supervisory Board itself, 

provided there will be at least three Supervisory Board members. Our articles of association provide that 

members of the Supervisory Board are appointed by the general meeting of shareholders upon a binding 

 
 
PAGE 35 / 111 
Corporate Governance 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

nomination by the Supervisory Board. Our general meeting of shareholders may at all times deprive such a 

nomination of its binding character by a resolution passed by at least two-thirds of the votes cast 

representing more than 50% of our issued share capital, following which our Supervisory Board shall draw up 

a new binding nomination.  

Our Supervisory Board rules provide that members of our Supervisory Board will serve for a maximum 

duration of three terms of four years. Our articles of association provide that the Supervisory Board 

members must retire periodically in accordance with a rotation schedule adopted by the Supervisory Board. 

A Supervisory Board member who retires in accordance with the rotation schedule can be reappointed 

immediately. The Supervisory Board appoints a chairman from among its members.  

With the exception of Dinko Valerio, each member of our Supervisory Board has been and remains fully 

independent within the meaning of best practice provision 2.1.8 of the DCGC. Mr. Dinko Valerio has provided 

a convertible loan to Amylon Therapeutics B.V. This loan becomes payable on demand after 24 months in 

equal quarterly terms. He is therefore not independent within the meaning of best practice provision 2.1.8 of 

the Code. We feel his membership of the supervisory board is justified by his specific knowledge and 

experience of our business. Moreover, we do comply with best practice provision 2.1.7 of the DCGC, as only 

one out of 6 supervisory board members are not independent under best practice provision 2.1.8 of the Code 

and they are so under different criteria of said provision 2.1.8. 

Under our articles of association, the general meeting of shareholders may suspend or remove Supervisory 

Board members at any time. A resolution of our general meeting of shareholders to suspend or remove a 

Supervisory Board member may be passed by a simple majority of the votes cast, provided that the 

resolution is based on a proposal by our Supervisory Board. In the absence of a proposal by our Supervisory 

Board, a resolution of our general meeting of shareholders to suspend or remove a Supervisory Board 

member shall require a majority of at least two-thirds of the votes cast representing more than 50% of our 

issued share capital.  

In a meeting of the Supervisory Board, each Supervisory Board member is entitled to cast one vote. A 

Supervisory Board member may grant a written proxy to another Supervisory Board member to represent 

him at a meeting of the Supervisory Board. All resolutions by our Supervisory Board are adopted by a simple 

majority of the votes cast unless our Supervisory Board rules provide otherwise. In case of a tie in any vote of 

the Supervisory Board, the chairman of the Supervisory Board shall have the casting vote. Our Supervisory 

Board may also adopt resolutions outside a meeting, provided that such resolutions are adopted in writing, 

all Supervisory Board members are familiar with the resolution to be passed and provided that no 

Supervisory Board member objects to such decision-making process. 

A succession plan for Supervisory Board members is in place that is aimed at retaining the balance in the 

requisite expertise, experience and diversity. 

Committees of the Supervisory Board  

In 2021, the Supervisory Board had an audit committee, a compensation, nominating and corporate 

governance committee and a research and development committee. We adopted a charter for each of these 

committees.  

Audit Committee  

Our audit committee consists of Bart Filius (chairman), Alison Lawton and Antoine Papiernik. Each member 

satisfies the independence requirements of the NASDAQ listing standards / Rule 10A-3(b)(1) under the 

Exchange Act, and each member meets the criteria for independence set forth in best practice 2.1.8 of the 

DCGC. Bart Filius qualifies as an “audit committee financial expert,” as defined by the SEC in Item 16A: “Audit

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Committee Financial Expert” and as determined by our Supervisory Board. The audit committee oversees our 

accounting and financial reporting processes and the audits of our financial statements. The audit committee 

is responsible for, among other things:  

• 

•

the operation of the internal risk management and control systems, including supervision of the 

enforcement of relevant primary and secondary legislation, and supervising the operation of codes of 

conduct; 

the provision of financial information by the company (choice of accounting policies, application and 

assessment of the effects of new rules, information about the handling of estimated items in the 

financial statements, forecasts, work of internal and external auditors, etc.); 

compliance with recommendations and observations of internal and external auditors; 

the policy of the company on tax planning; 

relations with the external auditor, including, in particular, his independence, remuneration and any 

non-audit services for the company; 

the financing of the company; 

the applications of information and communication technology, including risks relating to cyber 

security; and 

annually reviewing the need for an internal audit function: the Supervisory Board has decided not to 

create an internal audit function for the time being, since the current scope of the business does not 

justify such a fulltime role. The Supervisory Board has delegated an active role to its Audit Committee in 

the design, implementation and monitoring of internal risk management and control system to manage 

the significant risks to which the Company is exposed. 

Compensation, Nominating and Corporate Governance Committee  

Our compensation, nominating and corporate governance committee consists of James Shannon (chairman), 

Dinko Valerio and Alison Lawton. Each member satisfies the independence requirements of the NASDAQ 

listing standards. In addition, each member meets the criteria for independence set forth in best practice 

provision 2.1.8 of the DCGC, with the exception of Mr. Dinko Valerio. With respect to compensation matters, 

the compensation, nominating and corporate governance committee assists our supervisory board in 

reviewing and approving or recommending our compensation structure, including all forms of compensation 

relating to our supervisory board members, our management board members and our officers. Members of 

our management board may not be present at any compensation committee meeting while their 

compensation is deliberated. With respect to nominating and corporate governance matters, the 

compensation, nominating and corporate governance committee assists our supervisory board in selecting 

individuals qualified to become our supervisory board members and management board members, in 

determining the composition of the management board, supervisory board and its committees and our 

officers and in developing and recommending a set of corporate governance guidelines applicable to the 

company. Subject to and in accordance with the terms of the compensation policy approved by our general 

meeting of shareholders from time to time, as required by Dutch law, the compensation, nominating and 

corporate governance committee is responsible for, among other things:  

• 

• 

• 
• 

reviewing and making recommendations to the supervisory board with respect to compensation of our 

management board and supervisory board members; 

reviewing and approving the compensation, including equity compensation, change-of-control benefits 

and severance arrangements, of our officers (not part of our management board or supervisory board) 

as it deems appropriate; 

overseeing the evaluation of our management board members and our officers; 

reviewing periodically and making recommendations to our supervisory board with respect to any 

incentive compensation and equity plans, programs or similar arrangements;

Insurance and Indemnification of Management Board and Supervisory Board Members  

Under Dutch law, Management Board members, Supervisory Board members and certain other 

representatives may be held liable for damages in the event of improper or negligent performance of their 

duties. They may be held jointly and severally liable for damages to the Company for infringement of the 

articles of association or of certain provisions of the Dutch Civil Code. They may also be liable towards third 

parties for infringement of certain provisions of the Dutch Civil Code. In certain circumstances they may also 

incur additional specific civil and criminal liabilities.  

Our articles of association provide that we will indemnify our Management Board members, Supervisory 

Board members, former Management Board members and former Supervisory Board members (each an 

“Indemnified Person”) against (i) any financial losses or damages incurred by such Indemnified Person and 

(ii) any expense reasonably paid or incurred by such Indemnified Person in connection with any threatened, 

pending or completed suit, claim, action or legal proceedings, whether civil, criminal, administrative or 

 
 
 
PAGE 38 / 111 
Corporate Governance 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

investigative and whether formal or informal, in which he becomes involved, to the extent this relates to his 

position with the Company, in each case to the fullest extent permitted by applicable law. No indemnification 

shall be given to an Indemnified Person (a) if a Dutch court has established, without possibility for appeal, 

that the acts or omissions of such Indemnified Person that led to the financial losses, damages, suit, claim, 

action or legal proceedings result from either an improper performance of his duties as an officer of the 

Company or an unlawful or illegal act and (b) to the extent that his financial losses, damages and expenses 

are covered by an insurance and the insurer has settled these financial losses, damages and expenses (or has 

indicated that it would do so). Our Supervisory Board may stipulate additional terms, conditions and 

restrictions in relation to such indemnification.  

Board composition and diversity 

Our Supervisory Board has four male members and one female member. Our management board and the 

management team is comprised of six people, two female and four male members. As a Company, we 

support diversity of culture, gender and age in our Company. ProQR maintains a culture that reflects that 

ProQR is a multicultural company representing employees from over twenty countries. The culture is 

represented by the commitment to conducting our business ethically and to observing applicable laws, rules 

and regulations. In this context the Code of Conduct and Whistleblower policy are implemented and strongly 

anchored in the organization. Effectiveness of the Code of Conduct is monitored periodically. 

Our current Management Board and Supervisory Board members were selected based on the required 

profile and talent and abilities of the members without positive or negative bias on gender, culture or age. In 

the future, this will continue to be our basis for selection of new Board members or employees. 

General Meeting of Shareholders 

General meetings of shareholders can be held in Leiden, Amsterdam, Rotterdam, Schiphol Airport 

(municipality Haarlemmermeer), The Hague, Oegstgeest, Leidschendam, Katwijk, Noordwijk or Wassenaar, 

the Netherlands, or via video conference. All shareholders and others entitled to attend general meetings of 

shareholders are authorized to attend the general meeting of shareholders, to address the meeting and, in 

so far as they have such right, to vote, either in person or by proxy.  

Annually, at least one general meeting of shareholders shall be held, within six months after the end of our 

financial year. A general meeting of shareholders shall also be held within three months after our 

Management Board has considered it to be likely that the Company’s equity has decreased to an amount 

equal to or lower than half of its paid up and called up capital. If the Management Board and Supervisory 

Board have failed to ensure that such general meetings of shareholders as referred to in the preceding 

sentences are held in a timely fashion, each shareholder and other person entitled to attend shareholders’ 

meetings may be authorized by the Dutch court to convene the general meeting of shareholders. 

Our Management Board and our Supervisory Board may convene additional extraordinary general meetings 

of shareholders whenever they so decide. Pursuant to Dutch law, one or more shareholders and/or others 

entitled to attend general meetings of shareholders, alone or jointly representing at least ten percent of our 

issued share capital may on their application, be authorized by the Dutch court to convene a general meeting 

of shareholders. The Dutch court will disallow the application if it does not appear to it that the applicants 

have previously requested that the Management Board or Supervisory Board convenes a shareholders’ 

meeting and neither the Management Board nor the Supervisory Board has taken the necessary steps so that 

the shareholders’ meeting could be held within six weeks after the request.  

General meetings of shareholders are convened by a notice which includes an agenda stating the items to be 

discussed. For the annual general meeting of shareholders the agenda will include, among other things, the 

adoption of our annual accounts, the appropriation of our profits or losses, discharge of the members of the 

 
 
PAGE 39 / 111 
Corporate Governance 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Management Board for their management, discharge of the members of the Supervisory Board for their 

supervision on the management and proposals relating to the composition and filling of any vacancies of the 

Management Board or Supervisory Board. In addition, the agenda for a general meeting of shareholders 

includes such items as have been included therein by our Management Board or our Supervisory Board. 

Pursuant to Dutch law, one or more shareholders and/or others entitled to attend general meetings of 

shareholders, alone or jointly representing at least 3% of the issued share capital have the right to request 

the inclusion of additional items on the agenda of shareholders’ meetings. Such requests must be made in 

writing, substantiated, or by a proposal for a resolution and received by us no later than the sixtieth day 

before the day the relevant general meeting is held. No resolutions will be adopted on items other than those 

which have been included in the agenda.  

We will give notice of each general meeting of shareholders by publication on our website and, to the extent 

required by applicable law, in a Dutch daily newspaper with national distribution, and in any other manner 

that we may be required to follow in order to comply with Dutch law, applicable stock exchange and SEC 

requirements. We will observe the statutory minimum convening notice period for a general meeting of 

shareholders.  

Pursuant to our articles of association, our Management Board may determine a record date 

(“registratiedatum”) of 28 calendar days prior to a general meeting of shareholders to establish which 

shareholders and others with meeting rights are entitled to attend and, if applicable, vote in the general 

meeting of shareholders. The record date, if any, and the manner in which shareholders can register and 

exercise their rights will be set out in the convocation notice of the general meeting. Our articles of 

association provide that a shareholder must notify the Company in writing of his identity and his intention to 

attend (or be represented at) the general meeting of shareholders, such notice to be received by us ultimately 

on the seventh day prior to the general meeting. If this requirement is not complied with or if upon direction 

of the Company to that effect no proper identification is provided by any person wishing to enter the general 

meeting of shareholders, the chairman of the general meeting of shareholders may, in his sole discretion, 

refuse entry to the shareholder or his proxy holder.  

Pursuant to our articles of association, our general meeting of shareholders is chaired by the chairman of our 

Supervisory Board. If the chairman of our Supervisory Board is absent and has not charged another person 

to chair the meeting in his place, the Supervisory Board members present at the meeting shall appoint one of 

them to be chairman. If no Supervisory Board members are present at the general meeting of shareholders, 

the general meeting of shareholders will be chaired by our CEO or, if our CEO is absent, another Managing 

Board member present at the meeting and, if none of them is present, the general meeting shall appoint its 

own chairman. The person who should chair the meeting may appoint another person in his stead.  

The chairman of the general meeting may decide at his discretion to admit other persons to the meeting. The 

chairman of the general meeting shall appoint another person present at the shareholders’ meeting to act as 

secretary and to minute the proceedings at the meeting. The chairman of the general meeting may instruct a 

civil law notary to draw up a notarial report of the proceedings at the Company’s expense, in which case no 

minutes need to be taken. The chairman of the general meeting is authorized to eject any person from the 

general meeting of shareholders if the chairman considers that person to disrupt the orderly proceedings. 

The general meeting of shareholders shall be conducted in the English language. 

Voting Rights and Quorum Requirements  

In accordance with Dutch law and our articles of association, each issued ordinary share and preferred share 

confers the right on the holder thereof to cast one vote at the general meeting of shareholders. The voting 

rights attached to any shares held by us or our direct or indirect subsidiaries are suspended as long as they 

 
 
 
PAGE 40 / 111 
Corporate Governance 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

are held in treasury. Dutch law does not permit cumulative voting for the election of Management Board 

members or Supervisory Board members.  

Voting rights may be exercised by shareholders or by a duly appointed proxy holder (the written proxy being 

acceptable to the chairman of the general meeting of shareholders) of a shareholder, which proxy holder 

need not be a shareholder. Our articles of association do not limit the number of shares that may be voted by 

a single shareholder.  

Under our articles of association, blank votes, abstentions and invalid votes shall not be counted as votes 

cast. Further, shares in respect of which a blank or invalid vote has been cast and shares in respect of which 

the person with meeting rights who is present or represented at the meeting has abstained from voting are 

counted when determining the part of the issued share capital that is present or represented at a general 

meeting of shareholders. The chairman of the general meeting shall determine the manner of voting and 

whether voting may take place by acclamation.  

In accordance with Dutch law and generally accepted business practices, our articles of association do not 

provide quorum requirements generally applicable to general meetings of shareholders. To this extent, our 

practice varies from the requirement of NASDAQ Listing Rule 5620(c), which requires an issuer to provide in 

its bylaws for a generally applicable quorum, and that such quorum may not be less than one-third of the 

outstanding voting shares.  

Resolutions of the general meeting of shareholders are adopted by a simple majority of votes cast without 

quorum requirement, except where Dutch law or our articles of association provide for a special majority 

and/or quorum in relation to specified resolutions.  

Anti-takeover provisions 

We have adopted several provisions that may have the effect of making a takeover of our Company more 

difficult or less attractive, including: 

• 

• 

• 

• 

• 

granting a perpetual and repeatedly exercisable call option to a protection foundation, which confers 

upon the protection foundation the right to acquire, under certain conditions, the number of preferred 

shares in the capital of the Company. The issuance of such preferred shares will occur upon the 

protection foundation’s exercise of the call option and will not require shareholder consent; 

the staggered four-year terms of our Supervisory Board members, as a result of which only 

approximately one-fourth of our Supervisory Board members will be subject to election in any one year; 

a provision that our Management Board members and Supervisory Board members may only be 

appointed upon a binding nomination by our Supervisory Board, which can be set aside by a two-thirds 

majority of our shareholders representing more than half of our issued share capital;  

a provision that our Management Board members and Supervisory Board members may only be 

removed by our general meeting of shareholders by a two-thirds majority of votes cast representing 

more than 50% of our issued share capital (unless the removal was proposed by the Supervisory Board); 

and  

a requirement that certain matters, including an amendment of our articles of association, may only be 

brought to our shareholders for a vote upon a proposal by our Management Board that has been 

approved by our Supervisory Board.

Corporate Governance 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

Deviations from the Dutch Corporate Governance Code 

The Code contains a “comply-or-explain” principle, offering the possibility to deviate from the Code as long as 

any such deviations are explained. We acknowledge the importance of good corporate governance. However, 

at this stage, we do not comply with all the provisions of the DCGC for specific reasons. The main deviations 

from best practice provisions are listed below. 

• 

Pursuant to the best practice provisions 3.1.2.vi and 3.1.2.vii of the DCGC, options granted to our 

Management Board members should not be exercisable during the first three years after the date of 

grant; shares granted to our Management Board members for no financial consideration should be 

retained by them for a period of at least five years or until they cease to hold office, whichever is the 

shorter period; and the number of options and/or shares granted to our management Board members 

should be dependent on the achievement of pre-determined performance criteria. We do not intend to 

comply with all of the above requirements as we believe it is in the best interest of the company to 

attract and retain highly skilled Management Board members on conditions based on market 

• 

• 

• 

• 

competitiveness.  

Pursuant to best practice provision 3.2.3 the remuneration of the Management Board in the event of 

dismissal may not exceed one year’s salary. The management services agreements with our 

Management Board members provide for a lump-sum equal to 24 months of the individual’s monthly 

gross fixed salary. Based on the risk profile of the Company and to be able to attract highly skilled 

management, we assumed this period to be appropriate. 

Best practice provision 3.3.2 prohibits the granting of shares or rights to shares to members of the 

Supervisory Board as compensation. It is common practice for companies listed on the NASDAQ Global 

Market to grant shares to the members of the Supervisory Board as compensation, in order to align the 

interests of the members of the Supervisory Board with our interests and those of our shareholders, 

and we have granted and expect to grant options to acquire ordinary shares to some of our Supervisory 

Board members.  

Pursuant to best practice provision 3.3.3, any shares held by Supervisory Board members are long-term 

investments. We do not request our Supervisory Board members to comply with this provision. We 

believe it is in the best interest of the Company not to apply this provision in order to be able to attract 

and retain highly skilled Supervisory Board members on internationally competitive terms. 

Best practice provision 4.3.3 provides that the general meeting of shareholders may pass a resolution to 

cancel the binding nature of a nomination for the appointment of a member of the Management Board 

or of the Supervisory Board or a resolution to dismiss such member by an absolute majority of the 

votes cast. It may be provided that such majority should represent a given proportion of the issued 

capital, but this proportion may not exceed one third. In addition, best practice 4.3.3 provides that if 

such proportion of the share capital is not represented at the meeting, but an absolute majority of the 

votes cast is in favor of a resolution to cancel the binding nature of the nomination, a new general 

meeting of shareholders will be convened where the resolution may be adopted by absolute majority, 

regardless of the proportion of the share capital represented at the meeting. Our articles of association 

provide that these resolutions can only be adopted with at least a 2/3 majority which must represent 

more than 50% of our issued capital, and that no such second meeting will be convened, because we 

believe that the decision to overrule a nomination by the Management Board or the Supervisory Board 

for the appointment or dismissal of a member of our Management Board or of our Supervisory Board 

must be widely supported by our shareholders.  

• 

Best practice provision 4.2.3 stipulates that meetings with analysts, presentations to analysts, 

presentations to investors and institutional investors and press conferences must be announced in 

advance on the Company’s website and by means of press releases. Provision must be made for all 

shareholders to follow these meetings and presentations in real time, for example by means of 

webcasting or telephone. After the meetings, the presentations must be posted on the Company’s 

website. We believe that enabling shareholders to follow in real time all the meetings with analysts, 

 
 
 
PAGE 42 / 111 
Corporate Governance 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

presentations to analysts and presentations to investors, would create an excessive burden on our 

resources and therefore, we do not intend to comply with all of the above requirements.  

• 

Best practice provision 4.2.2 stipulates that an outline policy on bilateral contacts with the shareholders 

shall be formulated and published on the Company’s website. The Company has not formulated such 

policy as it believes this is already covered by our regular process for public disclosure of information. 

Summary of significant corporate governance differences from NASDAQ Listing Standards 

Our ordinary shares are listed on NASDAQ. The Sarbanes-Oxley Act of 2002, as well as related rules 

subsequently implemented by the SEC, requires foreign private issuers, including our Company, to comply 

with various corporate governance practices. As a foreign private issuer, subject to certain exceptions, the 

NASDAQ listing standards permit a foreign private issuer to follow its home country practice in lieu of the 

NASDAQ listing standards. Our corporate governance practices differ in certain respects from those that U.S. 

companies must adopt in order to maintain a NASDAQ listing. The home country practices followed by our 

Company in lieu of NASDAQ rules are described below:  

•  We do not intend to follow NASDAQ’s quorum requirements applicable to meetings of shareholders. In 
accordance with Dutch law and generally accepted business practice, our articles of association do not 

provide quorum requirements generally applicable to general meetings of shareholders.  

•  We do not intend to follow NASDAQ’s requirements regarding the provision of proxy statements for 

general meetings of shareholders. Dutch law does not have a regulatory regime for the solicitation of 

proxies and the solicitation of proxies is not a generally accepted business practice in the Netherlands. 

We do intend to provide shareholders with an agenda and other relevant documents for the general 

meeting of shareholders and shareholders will be entitled to give proxies and voting instructions to us 

and/or third parties. 

We intend to take all actions necessary for us to maintain compliance as a foreign private issuer under the 

applicable corporate governance requirements of the Sarbanes-Oxley Act of 2002, the rules adopted by the 

SEC and NASDAQ’s listing standards. 

Controls and procedures 

In accordance with the Dutch Corporate Governance Code, we have assessed the design and operational 

effectiveness of our Risk & Control framework. Based on the activities performed during 2021, and in 

accordance with provision 1.4.3, the Management Board considers that: 

• 

• 

• 

• 

this report provides sufficient insights into any failings in the effectiveness of the internal risk 

management and control systems; 

the aforementioned systems provide reasonable assurance that the financial reporting does not contain 

any material inaccuracies; 

based on the current state of affairs, it is justified that the financial reporting is prepared on a going 

concern basis; and 

the report states those material risks and uncertainties that are relevant to the expectation of the 

company’s continuity for the period of twelve months after the preparation of this report. 

In accordance with the Dutch Financial Supervision Act, section 5.25c, the Management Board declares that, 

to the best of its knowledge: 

• 

the financial statements for 2021 provide, in accordance with IFRS as endorsed by the EU, a true and fair 

view of the consolidated assets, liabilities and financial position as at December 31, 2021, and of the 

2021 consolidated income statement of ProQR Therapeutics N.V.;  

 
 
PAGE 43 / 111 
Corporate Governance 

PROQR THERAPEUTICS ANNUAL REPORT 2021 

• 

the annual report provides a true and fair view of the situation as at December 31, 2021, and the state 

of affairs during the financial year 2021, together with a description of the principal risks faced by the 

Company.  

Diversity 

We value diversity as a way of recognizing and valuing the differences between individuals to come to the 

most efficient and effective way to achieve our strategic objectives. For our supervisory directors, this means 

that when making recommendations to the general meeting for the (re-)appointment of directors, the board 

will aim for a diverse composition in terms of such factors as gender and age, in accordance with our diversity 

policy as may be in force from time to time. Under Dutch law reporting rules, we will be required to address 

diversity of our supervisory directors in our Annual Report or in the report of the board of directors 

(bestuursverslag): (i) composition of the board of directors by gender; (ii) objectives of the diversity policy; (iii) 

description of how the diversity policy is being implemented and the results thereof and (iv) if there is no 

diversity policy, this should be explained. 

On January 1, 2022, new legislation entered into force, requiring “large Dutch companies” to set an 

‘appropriate and ambitious’ target for their management board, supervisory board and senior executives (the 

latter as determined by the company). If a company has adopted a one-tier board structure, the appropriate 

and ambitious target applies to both the executive and non-executive directors. The legislation is based on a 

“comply or explain” principle. Accordingly, we will be required to disclose in our report of the board of 

directors whether or not we are in compliance with the self-imposed target. In addition, within ten months of 

the end of the financial year, we will need to report to the Sociaal-Economische Raad (SER) whether or not we 

have complied with the self-imposed target. 

Our policy is that we will balance our board of directors in terms of gender, age, background and nationality 

as much as reasonably possible while still having our board composed of the best possible candidates 

overall. It has been and will remain our priority to have the best available specialists on our board of 

directors, irrespective of age, background, nationality and gender, who make a balanced panel of directors 

able to advise and guide ProQR to further growth and success for all its stakeholders. This means we require 

a number of specialties and character traits to be present. Taking into account the aforementioned and the 

specialist nature of our business, we will actively seek to further improve diversity on our board if and when 

proposing new appointments to our board of directors, whilst acknowledging that age, gender and 

nationality are important, but not the only factors relevant for the ultimate decision to select a board 

member. We have set ourselves the target to over time achieve an equal gender balance in our board of 

directors, and we will report on our progress annually in our corporate governance report.

Risk Management 

Our business is subject to numerous risks and uncertainties. In the table below, we focus on the key risks and 

uncertainties the Company currently faces. For the avoidance of doubt, this does not mean that the risks 

which were previously signaled and not described here are no longer relevant. For a complete understanding 

of the risks that we face you should also read the full list of risks and uncertainties as disclosed in item 3.D 

Risk Factors of the annual report on Form 20-F. Some of these risks and uncertainties are outside the control 

of the Company, others may be influenced or mitigated. In 2015, we have implemented a Risk & Control 

framework, based on the COSO 2013 internal control framework, for enhancing our control environment as 

well as compliance with the U.S. SEC’s Sarbanes Oxley (SOx) Act of 2002, which we are required to do as a 

company listed on the NASDAQ. As part of the SOx implementation program, our Risk & Control framework 

was further enhanced in 2021, focusing on business process, IT and entity level controls. Improvement of our 

Risk & Control framework is an ongoing effort for the Company. 

We have defined our risk tolerance on a number of internal and external factors including: 

• 
• 
• 
• 
• 
• 
• 

Financial strength in the long run; 

Liquidity in the short run;  

Business performance measures;  

Scientific risks and opportunities;  

Compliance with relevant rules and regulations;  

High turnover of staff; 

Reputation.  

The identification and analysis of risks is an ongoing process that is naturally a critical component of internal 

control. On the basis of these factors and ProQR’s risk tolerance, improvement of our Risk & Control 

framework and monitoring of the risks is an ongoing effort for the Company. 

Our main risks are those that threaten the achievement of the Company’s corporate objectives, including 

compliance. If any of these risks actually occurs, our business, prospects, operating results and financial 

condition could suffer materially. These risks include, but are not limited to, the following:  

Risk related to 

Risk area 

Development and 
Regulatory 
Approval of our 
Product 
Candidates 

Our products might not be 
able to demonstrate safety 
and efficacy in the preclinical 
studies and clinical trials that 
are needed to obtain product 
approval. 

Expected impact upon 
materialization 

The Company would be unable to 
commercialize the products and 
therefore generate revenues. 

Risk appetite /  
risk-mitigating actions 

This is an inherent risk with 
drug development as the 
safety and efficacy of 
products can only be 
assessed when these 
studies are conducted. 
However, the Company has 
multiple products in the 
pipeline and therefore is 
diversified. The Company 
also monitors the progress 
of the programs and aims to 
make decisions that 
mitigate safety and efficacy 
related risks. 

 
 
 
 
 
 
 
 
 
 
 
 
 
Risk related to 

Risk area 

The regulatory approval 
process is lengthy, time-
consuming and unpredictable 
and products developed may 
ultimately not lead to 
regulatory approval of the 
product. 

We may not able to maintain 
orphan product status for 
sepofarsen and ultevursen or 
maintain / obtain such status 
for any other product 
canditates. 

We may be precluded from 
obtaining marketing 
authorization for our 
products when our 
competitors have obtained 
market exclusivity before we 
do. 

The Company depends 
largely on equity financing 
and financing through 
convertible debt, third party 
collaboration agreements 
and government subsidies.  

The Company relies upon 
third-party contractors and 
service providers for the 
execution of several aspects 
of its preclinical and clinical 
development programs, 
which include CRO’s, third 
party manufacturers and 
other service providers. 

The Company is highly 
dependent on its portfolio of 
patents and other intellectual 
property, proprietary 
information and knowhow 
and its ability to protect and 
enforce these assets.  

The Company is subject to 
the risk of infringing third 
party intellectual property 
rights.

Expected impact upon 
materialization 

Failure to comply with the 
requirements in the regulatory 
process could result in delays, 
suspension, refusals and 
withdrawal of approvals as well as 
fines. 

We may not benefit from rewards 
including fee reduc-tions and 
market exclusivity. Sales could be 
impacted if other products are 
granted authorization for the 
same indications as sepofarsen or 
ultevursen. 

We may encounter delays in 
marketing our products for a 
significant period of time. 

Volatility of the Company’s share 
price, failure to deliver under loan 
or collaboration agreements 
and/or the reevaluation or 
withdrawal of government 
subsidies may have a negative 
impact on the Company's ability to 
obtain future financing. 

Failure of third parties to provide 
services of a suitable quality and 
within acceptable timeframes may 
cause delay or failure of the 
Company's development 
programs. 

Inadequate intellectual property 
protection or enforcement may 
impede the Company’s ability to 
compete effectively. If the 
Company is not able to protect its 
trade secrets, know-how or other 
proprietary information, the value 
of its technology and product 
candidates could be significantly 
diminished. Intellectual property 
rights conflicts may result in costly 
litigation and could result in the 
Company having to pay 
substantial damages or limit the 
Company’s ability to 
commercialize its product 
candidates. 

Risk-mitigating actions 

Although the Company 
monitors the regulatory 
landscape and engages with 
the authorities when it 
deems that necessary, this 
is an inherent risk in biotech 
drug development and 
therefore has limited 
mitigation abilities. 

We take orphan drug 
requirements into 
consideration in the design 
of our clinical development 
plans. 

We take orphan drug 
requirements into 
consideration in the design 
of our clinical development 
plans. 

The ability of third-party 
financing is dependent on 
external factors and is 
therefore not entirely in the 
Company’s control. The 
Company monitors the 
market conditions for 
opportunities to add 
additional capital. 

The Company reviews and 
monitors the activities of 
the third parties. These 
include setting contractual 
deliverables, quality 
assurance audits and 
performance reports, 
among other activities. 

The Company files and 
prosecutes patent 
applications to protect its 
products and technologies 
to the best of its knowledge 
and with assistance from 
internal and external 
counsel. Prior to disclosing 
any confidential information 
to third parties, the 
Company maintains strict 
confidentiality standards 
and agreements for 
collaborating parties.

Risk related to 

Risk area 

Commercialization 
of Our Product 
Candidates 

We face competition from 
entities that have developed 
or may develop product 
candidates for our target 
indications.  

Reimbursement 
from third-party 
payors 

The availability of 
reimbursement by 
governmental and private 
payors is essential for most 
patients to be able to afford 
expensive treatments. Sales 
of any of our product 
candidates, if approved, will 
depend substantially on the 
extent to which the costs of 
these product candidates will 
be paid by health 
maintenance, managed care, 
pharmacy benefit and similar 
healthcare management 
organizations, or reimbursed 
by government health 
administration authorities, 
private health coverage 
insurers and other third-party 
payors. 

Expected impact upon 
materialization 

If our competitors develop 
technologies or product 
candidates more rapidly than we 
do or their technologies, including 
delivery technologies, are more 
effective, our ability to develop 
and successfully commercialize 
our product candidates may be 
adversely affected. 

If reimbursement is not available, 
or is available only to limited 
levels, we may not be able to 
successfully commercialize any 
product candidate. Even if 
coverage is provided, the 
approved reimbursement amount 
may not be high enough to allow 
us to establish or maintain pricing 
sufficient to realize a sufficient 
return on our investment. 

Risk-mitigating actions 

Competition is an inherent 
risk for any industry 
including drug 
development. Through our 
IP strategy and orphan drug 
designation application, we 
attempt to have data 
exclusivity for our products. 
Development in other 
companies is essentially out 
of our control but we 
monitor the competitive 
landscape and incorporate 
that into our business 
strategy. 

The ability of third-party 
financing is dependent on 
external factors and is 
therefore not entirely in the 
Company’s control. The 
Company monitors the 
market conditions for 
opportunities to seek 
reimbursement. 

As to the materialization of the above risks, in February 2022 the Company announced the top-line results 

from the phase 2/3 Illuminate trial of sepofarsen in CEP290-mediated LCA10. The study did not meet its 

primary endpoint nor any notable secondary endpoints. No benefit was observed in either treatment arm 

versus the sham arm.  

In addition to the above key risks, the Company’s activities expose it to a variety of financial risks: market risk 

(including currency risk, interest rate risk and price risk), credit risk and liquidity risk. Unfavorable exchange 

rate developments and historically low interest rates may impact the financial income of the Company. The 

Company has a cash management policy in place to minimize potential adverse effects resulting from 

unpredictability of financial markets on the Company’s financial performance.

Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

Notes to the consolidated financial statements for the year ended December 
31, 2021 

1. General Information  

ProQR Therapeutics N.V., or “ProQR” or the “Company”, is a development stage company domiciled in the 

Netherlands that primarily focuses on the development and commercialization of novel therapeutic 

medicines.  

Since September 18, 2014, the Company’s ordinary shares are listed on the NASDAQ Global Market under 

ticker symbol PRQR. 

The Company was incorporated in the Netherlands, on February 21, 2012 (Chamber of Commerce no. 

54600790) and was reorganized from a private company with limited liability to a public company with limited 

liability on September 23, 2014. The Company has its statutory seat in Leiden, the Netherlands and is 

registered in the Trade Register at the Chamber of Commerce under number 54600790. The address of its 

headquarters and registered office is Zernikedreef 9, 2333 CK Leiden, the Netherlands. 

At December 31, 2021, ProQR Therapeutics N.V. is the ultimate parent company of the following entities:

As used in these consolidated financial statements, unless the context indicates otherwise, all references to 

“ProQR”, the “Company” or the “Group” refer to ProQR Therapeutics N.V. including its subsidiaries and the 

ESOP Foundation. 

2. Basis of preparation 

(a) Statement of compliance  
These consolidated financial statements have been prepared in accordance with International Financial 

Reporting Standards, or IFRS, as adopted by the European Union (“EU”).  

With reference to the income statement of the Company, use has been made of the exemption pursuant to 

Section 402 of Book 2 of the Netherlands Civil Code. 

 
 
 
PAGE 52 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

These financial statements were authorized for issue by the Company’s Management Board and its Senior 

Management on April 29, 2022.  

(b) Basis of measurement  
The financial statements have been prepared on the historical cost basis except for financial instruments and 

share-based payment obligations which have been based on fair value. Historical cost is generally based on 

the fair value of the consideration given in exchange for assets.  

(c) Functional and presentation currency 
These consolidated financial statements are presented in euro, which is the Company’s functional currency. 

All amounts have been rounded to the nearest thousand, unless otherwise indicated. 

(d) Going Concern  
The Management Board of ProQR has, upon preparing and finalizing the 2021 financial statements, assessed 

the Company’s ability to fund its operations for a period of at least one year after the date of signing these 

financial statements. Management has not identified significant going concern risks. 

The financial statements of the Company have been prepared on the basis of the going concern assumption 

based on its existing funding, taking into account the Company’s current cash position and the projected cash 

flows based on the activities under execution on the basis of ProQR’s business plan and budget. 

(e) Use of estimates and judgements  
In preparing these consolidated financial statements, management has made judgements, estimates and 

assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, 

income and expenses. Actual results may differ from these estimates.  

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates 

are recognized in the period in which the estimate is revised if the revision affects only that period or in the 

period of the revision and future periods if the revision affects both current and future periods.  

Information about assumptions and estimation uncertainties that may have a significant risk of resulting in a 

material adjustment is included below. 

(i) Revenue recognition for the Eli Lilly collaboration and license agreement 

a. Identification of the performance obligation 

Note 17 describes the Company’s collaboration and license agreement with Eli Lilly. Under this agreement, 

ProQR provides Eli Lilly with a license (with a right to sub-license) to exploit compounds resulting from the 

collaboration. A significant amount of judgement is required to determine whether the license is distinct from 

the other promises in the contract. The license was concluded not to be distinct from the other promises in 

the contract based on the following considerations: 

• 

• 

the license has no stand-alone value to Eli Lilly without the Company being involved in the research and 

development collaboration, and; 

there are significant interdependencies between the license and the research and development services 

to be provided by the Company. 

b. Determining the timing of satisfaction of performance obligations 

For the Eli Lilly collaboration, the Company recognizes revenue over time, using an input method that 

estimates the satisfaction of the performance obligation as the percentage of labor hours incurred compared 

to the total estimated labor hours required to complete the promised services. As our estimate of the total 

 
 
PAGE 53 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

labor hours required is dependent on the evolution of the research and development activities, it may be 

subject to change. If the progression and/or outcome of certain research and development activities would 

be different from the assumptions that were made during the preparation of these financial statements, this 

could lead to material adjustments to the total estimated labor hours, which might result in a reallocation of 

revenue between current and future periods. Our total deferred revenue balance related to this Eli Lilly 

performance obligation amounts to € 19,143,000 at December 31, 2021. 

c. Determining the transaction price 

The Company applied judgement to determine whether the equity investment made by Eli Lilly in ProQR is 

part of the transaction price for the collaboration and license agreement. The Company concluded that the 

premium that Eli Lilly paid above the closing price on the day of entering into the equity investment 

agreement was paid because of the Company’s existing obligations to deliver research and development 

services to Eli Lilly under the terms of the collaboration and license agreement. Therefore, the equity 

investment is considered to be part of the transaction price. The contract also includes variable 

consideration, but no variable consideration was included in the transaction price, as it is not highly probable 

that a significant reversal in the amount of cumulative revenue recognized will not occur when the 

uncertainty associated with the variable consideration is subsequently resolved. 

(ii) Research and development expenditures  

Research expenditures are reflected in the income statement. Development expenses are currently also 

reflected in the income statement because the criteria for capitalization are not met. At each balance sheet 

date, the Company estimates the level of service performed by the vendors and the associated costs incurred 

for the services performed. 

Although we do not expect the estimates to be materially different from amounts actually incurred, the 

understanding of the status and timing of services performed relative to the actual status and timing of 

services performed may vary and could result in reporting amounts that are too high or too low in any 

particular period.  

(iii) Convertible debt 

The terms of our convertible debt agreements are evaluated to determine whether the convertible debt 

instruments contain both liability and equity components, in which case the instrument is a compound 

financial instrument. Convertible debt agreements are also evaluated to determine whether they contain 

embedded derivatives, in which case the instrument is a hybrid financial instrument. Judgement is required 

to determine the classification of such financial instruments based on the terms and conditions of the 

convertible debt agreements, the currencies in which the debt instruments are denominated and the 

Company’s functional currency. 

Estimation methods are used to determine the fair values of the liability and equity components of 

compound financial instruments and to determine the fair value of embedded derivatives included in hybrid 

financial instruments. The determination of the effective interest used for the host contracts of hybrid 

financial instruments and the liability components of compound financial instruments is dependent on the 

outcome of such estimations. Evaluating the reasonableness of these estimations and the assumptions and 

inputs used in the valuation methods requires a significant amount of judgement and is therefore subject to 

an inherent risk of error. 

(f) Changes in accounting policies  
The following Standards and Interpretations became effective for annual reporting periods beginning on or 

after January 1, 2021: 

 
 
 
PAGE 54 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

• 
• 

IBOR reform Phase 2 amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16; 

Covid-19-Related Rent Concessions Amendment to IFRS 16; 

None of these new Standards and Interpretations had a material impact on our financial statements. No 

changes in accounting policies occurred in 2021 

3. Significant Accounting Policies  

The Company has consistently applied the following accounting policies to all periods presented in these 

consolidated financial statements. 

(a) Basis of consolidation 
(i) Subsidiaries 

Subsidiaries are entities controlled by the Company. The Company controls an entity when it has power over 

the entity, is exposed to, or has rights to, variable returns from its involvement with the entity and has the 

ability to affect those returns through its power over the entity. The Company reassesses whether or not it 

controls an entity if facts and circumstances indicate that there are changes to one or more of these 

elements. The financial statements of subsidiaries are included in the consolidated financial statements from 

the date on which control commences until the date on which control ceases. 

(ii) Non-controlling interests (“NCI”) 

NCI are measured at their proportionate share of the acquiree's identifiable net assets at the acquisition 

date. Changes in the Company 's interest in a subsidiary that do not result in a loss of control are accounted 

for as equity transactions. 

(iii) Loss of control 

When the Company loses control over a subsidiary, it derecognizes the assets and liabilities of the subsidiary, 

and any non-controlling interests and other components of equity. Any resulting gain or loss is recognized in 

profit or loss. Any interest retained in the former subsidiary is measured at fair value when control is lost.  

(iv) Transactions eliminated on consolidation 

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group 

transactions, are eliminated. Unrealized gains arising from transactions with equity-accounted investees are 

eliminated against the investment to the extent of the Company’s interest in the investee. Unrealized losses 

are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of 

impairment. 

(v) Associates 

Associates are entities over which the Company has significant influence. Significant influence is the power to 

participate in the financial and operating policy decisions of the investee but is not control or joint control 

over those policies.  

Investments in associates are accounted for in the consolidated financial statements using the equity method 

of accounting. Equity accounting involves recording the investment in associates initially at cost, and 

recognizing the Company’s share of the post-acquisition results of associates in the consolidated income 

statement and the Company’s share of post-acquisition other comprehensive income in consolidated other 

comprehensive income. The cumulative post-acquisition movements are adjusted against the carrying 

amount of the investments in associates in the consolidated statement of financial position. 

 
 
PAGE 55 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

When the Company’s share of losses in an associate equals or exceeds its interest in the associate, the 

Company does not recognize further losses unless it has incurred or guaranteed obligations in respect of the 

associate. 

(b) Classes of financial instruments  
Financial instruments are both primary financial instruments, such as receivables and payables, and financial 

derivatives. For the Company’s primary financial instruments, reference is made to the treatment per the 

corresponding balance sheet item.  

Financial derivatives are valued at fair value. Upon first recognition, financial derivatives are recognized at fair 

value and then revalued as at balance sheet date. Changes in the fair value of derivatives are generally 

recognized in profit or loss. If the Company is involved with hybrid contracts, the Company applies the 

following with regard to the embedded derivatives in the hybrid contract. Embedded derivatives are 

separated from the host contract and accounted for separately if the host contract is not a financial asset and 

the following criteria are met: 

• 

• 

• 

the economic characteristics and risk of the embedded derivative are not closely related to the 

economic characteristics and risks of the host contract; 

a separate instrument with the same terms as the embedded derivative would meet the definition of a 

derivate; and 

the hybrid contract is not measured at fair value with changes in fair value recognized in profit or loss.  

If an embedded derivative is separated from the hybrid contract, the host contract is accounted for in 

accordance with the determined policies for such a contract. The embedded derivative is accounted for in 

accordance with the Company’s principles for the applicable derivatives.   

(c) Foreign currencies  
(i) Foreign currency transactions 

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing 

at the dates of the transactions.  

Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency 

at the exchange rate at the reporting date. Non-monetary assets and liabilities denominated in foreign 

currencies that are measured at fair value are translated into the functional currency at the exchange rate 

when the fair value was determined. Foreign currency differences are generally recognized in profit or loss. 

Non-monetary items that are measured based on historical cost in a foreign currency are translated at the 

exchange rate prevailing at the date of the transaction. 

(ii) Foreign operations 

The assets and liabilities of foreign operations are translated into euro at exchange rates at the reporting 

date. The income and expenses of foreign operations are translated into euros at the exchange rates at the 

dates of the transactions. Foreign currency differences are recognized in OCI and accumulated in the 

translation reserve, except to the extent that the translation difference is allocated to NCI. 

(d) Revenue 
Revenues to date have consisted principally of non-refundable upfront fees and research and development 

service fees in connection with collaboration and license agreements. The Company recognizes revenue 

when its customers obtain control of promised goods or services, in an amount that reflects the 

consideration that the Company expects to receive in exchange for those goods and services. Revenue is 

recognized for agreements that are in scope of IFRS 15 Revenue, based on the following five steps: 

 
 
 
PAGE 56 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

(i) Identify the contract 

The Company entered into collaboration and license agreements in which the Company licenses its 

intellectual property and/or provides research and development services. These arrangements include 

upfront payments, milestone payments based on clinical and regulatory criteria, research and development 

service fees and future sales-based milestones and sales-based royalties. In some cases, concurrently with 

the collaboration and license agreements, the Company enters into share purchase agreements with the 

customer. If this is the case, the Company analyzes whether the criteria to combine contracts, as set out by 

IFRS 15, are met. 

(ii) Identify performance obligations 

Contracts with customers can have one or more distinct performance obligations under IFRS 15. Identifying 

the performance obligations is based on an assessment of whether the promises in an agreement are 

capable of being distinct and are distinct from the other promises to transfer goods and/or services in the 

context of the contract. The Company assessed that there is one single performance obligation in our 

material ongoing collaboration and license agreements, being the transfer of a license combined with 

performance of research and development services. 

This is because the Company considers the performance obligations cannot be distinct in the context of the 

contract as the licenses have no stand-alone value without the Company being involved in the research and 

development collaboration and that there is interdependence between the license and the research and 

development services to be provided. 

(iii) Determine the transaction price 

Our collaboration and license agreements include non-refundable upfront payments; equity components; 

milestone payments, the receipt of which is dependent upon the achievement of certain clinical, regulatory or 

commercial milestones; royalties on sales and research and development service fees. 

a.  Non-refundable upfront payments or license fees 
If the license to the Company’s intellectual property is determined to be distinct from the other performance 

obligations identified in the arrangement, the Company recognizes revenue from non-refundable upfront 

fees allocated to this license at the point in time the license is transferred to the customer and the customer 

has the right to use the license. 

For all our material ongoing collaboration and license agreements, the Company considers the performance 

obligations related to the transfer of the license as not distinct from the other promises to transfer goods 

and/or services; the Company uses judgement to assess the nature of the combined performance obligation 

to determine whether the combined performance obligation is satisfied over time or at a point in time. If over 

time, revenue is then recognized based on a pattern that best reflects the transfer of control of the service to 

the customer. 

b.  Milestone payments other than sales-based milestones 
A milestone payment, being a variable consideration, is only included in the transaction price to the extent it 

is highly probable that a significant reversal in the amount of cumulative revenue recognition will not occur 

when the uncertainty associated with the variable consideration is subsequently resolved. The Company 

estimates the amount to be included in the transaction price upon achievement of the milestone event. The 

transaction price is then allocated to each performance obligation on a stand-alone selling price basis, for 

which the Company recognizes revenue as or when the performance obligations under the contract are 

satisfied. At the end of each reporting period, the Company re-evaluates the probability of achievement of 

such milestones and any related constraint, and, if necessary, adjusts the estimate of the overall transaction 

 
 
PAGE 57 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and 

earnings in the period of adjustment. 

c.  Research and development service fees 
Our collaboration and license agreements may include reimbursement for research and development 

services. R&D services are performed and satisfied over time because the customer simultaneously receives 

and consumes the benefits provided by us. Revenue associated with such R&D service fees is then recognized 

based on a pattern that best reflects the transfer of control of the service to the customer. 

d.  Sales based milestone payments and royalties 
Our material collaboration and license agreements include sales-based royalties, including commercial 

milestone payments based on the level of sales. The Company concluded that the licenses are not the 

predominant items to which the royalties and commercial milestone payments relate. Related revenue will be 

recognized as the subsequent underlying sales occur. 

(iv) Allocate the transaction price 

An entity shall allocate the transaction price to each performance obligation identified in a contract on a 

relative stand-alone selling price basis. As our collaboration and license agreements only contain one single 

performance obligation, the transaction price is entirely allocated to this single performance obligation. 

(v) Recognize revenue 

Revenue is recognized when the customer obtains control of the goods and/or services as provided in the 

collaboration and license agreements. Control can be transferred over time or at a point in time, which 

results in the recognition of revenue either over time or at a point in time. 

Our license and collaboration agreements only contain one single performance obligation, in which the 

Company’s performance creates and subsequently enhances assets (e.g. exploitable compounds) that the 

customers control as the assets are created and/or enhanced. As such, the Company recognizes revenue 

over time. 

The recognition of revenue over time is based on a pattern that best reflects the satisfaction of the related 

performance obligation, applying the input method. The input method estimates the satisfaction of the 

performance obligation as the percentage of labor hours incurred compared to the total estimated labor 

hours required to complete the promised services. 

(e) Other income  
Other income includes amounts earned from third parties and are recognized when earned in accordance 

with the substance and under the terms of the related agreements and when it is probable that the economic 

benefits associated with the transaction will flow to the Company and the amount of the income can be 

measured reliably. The grants are recognized in other income on a systematic basis over the period the 

Company recognizes as expenses the related costs for which the grants are expected to compensate. 

(f) Government grants —WBSO  
The WBSO (“afdrachtvermindering speur- en ontwikkelingswerk”) is a Dutch fiscal facility that provides 

subsidies to companies, knowledge centers and self-employed people who perform research and 

development activities (as defined in the WBSO Act). Under this Act, a contribution is paid towards the labor 

costs of employees directly involved in research and development. The contribution is in the form of a 

reduction of payroll taxes and social security contributions recognized on a net basis within the labor costs. 

This reduction of payroll taxes and social security contributions is classified under research and 

developments costs. 

 
 
 
PAGE 58 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

(Government) Grant income is not recognized until there is reasonable assurance that the Company will 

comply with the conditions attached to them. (Government) Grants are recognized in profit or loss on a 

systematic basis over the period the Company recognizes as expenses the related costs for which the grants 

are intended to compensate. 

(g) Employee benefits  
(i) Short-term employee benefits 

Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the 

amount expected to be paid if the Company has a present legal or constructive obligation to pay this amount 

as a result of past service provided by the employee and the obligation can be estimated reliably. 

(ii) Share-based payment transactions  

The grant-date fair value of equity-settled share-based payment awards granted to employees is generally 

recognized as an expense, with a corresponding increase in equity, over the vesting period of the awards. The 

amount recognized as an expense is adjusted to reflect the number of awards for which the related service 

and non-market performance conditions are expected to be met, such that the amount ultimately recognized 

is based on the number of awards that meet the related service conditions at the vesting date. For share-

based payment awards with non-vesting conditions, the grant-date fair value of the share-based payment is 

measured to reflect such conditions and there is no true-up for differences between expected and actual 

outcomes. 

(iii) Pension obligations  

The Company operates defined contribution pension plans for all employees funded through payments to 

insurance companies. The Company has no legal or constructive obligation to pay further contributions once 

the contributions have been paid. The contributions are recognized as employee benefit expense when 

employees have rendered the service entitling them to the contributions. Prepaid contributions are 

recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.  

(h) Taxation  
Income tax expense represents the sum of the tax currently payable and deferred tax. It is recognized in 

profit or loss except to the extent that it relates to a business combination, or items recognized directly in 

equity or in OCI. 

(i) Current tax  

The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported 

in the income statement because of items of income or expense that are taxable or deductible in other years 

and items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax 

rates that have been enacted or substantively enacted by the end of the reporting period. 

(ii) Deferred tax  

Deferred tax is recognized on differences between the carrying amounts of assets and liabilities in the 

financial statements and the corresponding tax bases used in the computation of taxable profit.  

The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to 

the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the 

asset to be recovered. Since the Company does not expect to be profitable in the foreseeable future, its 

deferred tax assets are valued at nil.  

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in 

which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or 

 
 
PAGE 59 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and 

assets reflects the tax consequences that would follow from the manner in which the Company expects, at 

the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.  

(i) Property, plant and equipment 
(i) Recognition and measurement 

Items of property, plant and equipment are measured at cost less accumulated depreciation and any 

accumulated impairment losses. If significant parts of an item of property, plant and equipment have 

different useful lives, then they are accounted for as separate items (major components) of property, plant 

and equipment. Any gain or loss on disposal of an item of property, plant and equipment is recognized in 

profit or loss. 

(ii) Depreciation 

Depreciation is calculated to write off the cost of items of property, plant and equipment less their estimated 

residual values using the straight-line method over their estimated useful lives, and is recognized in profit or 

loss. Right-of-use assets are depreciated over the shorter of the lease term and their useful lives unless it is 

reasonably certain that the Company will obtain ownership by the end of the lease term.  

The estimated useful lives of property, plant and equipment for current and comparative periods are as 

follows: 

• 
• 
• 

Buildings and leasehold improvements:  

5 - 10 years; 

Laboratory equipment:  

Other:  

5 years; 

3 - 5 years. 

Depreciation methods, useful lives and residual values are reviewed at each reporting date and adjusted if 

appropriate. 

(j) Intangible assets 
Expenditure on research activities is recognized as an expense in the period in which it is incurred. An 

internally-generated intangible asset arising from development (or from the development phase of an 

internal project) is recognized if, and only if, all of the following have been demonstrated: 

• 
• 
• 
• 
• 

• 
• 

the technical feasibility of completing the intangible asset so that it will be available for use or sale; 

the intention to complete the intangible asset and use or sell it; 

the ability to use or sell the intangible asset; 

how the intangible asset will generate probable future economic benefits; 

the availability of adequate technical, financial and other resources to complete the development and to 

use 

or sell the intangible asset; and 

the ability to measure reliably the expenditure attributable to the intangible asset during its 

development. 

The amount initially recognized for internally-generated intangible assets is the sum of the expenditure 

incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no 

internally generated intangible asset can be recognized, development expenditures are recognized in the 

consolidated statements of profit and loss and other comprehensive income in the period in which they are 

incurred. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
PAGE 60 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

Due to uncertainties inherent to the development and registration with the relevant healthcare authorities of 

its products, the Company estimates that the conditions for capitalization are not met until the regulatory 

procedures required by such healthcare authorities have been finalized. The Company currently does not 

own products that have been approved by the relevant healthcare authorities and this has resulted in all 

development costs being recognized as an expense in the period in which they are incurred  

(k) Impairment of assets  
At the end of each reporting period, the Company reviews the carrying amounts of its non-current assets, 

including right-of-use assets, to determine whether there is any indication that those assets have suffered an 

impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to 

determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable 

amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to 

which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate 

assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest 

group of cash-generating units for which a reasonable and consistent allocation basis can be identified. 

The recoverable amount is the higher of fair value less costs of disposal and value in use. In assessing value in 

use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that 

reflects current market assessments of the time value of money and the risks specific to the asset for which 

the estimates of future cash flows have not been adjusted. 

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying 

amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An 

impairment loss is recognized immediately in profit or loss. 

Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) 

is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount 

does not exceed the carrying amount that would have been determined had no impairment loss been 

recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is 

recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which 

case the reversal of the impairment loss is treated as a revaluation increase.  

(l) Financial assets  
All financial assets are recognized and derecognized on the trade date where the purchase or sale of a 

financial asset is under a contract whose terms require delivery of the financial asset within the timeframe 

established by the market concerned, and are initially measured at fair value and subsequently measured at 

amortized cost or fair value on the basis of the entity’s business model for managing the financial assets and 

the contractual cash flow characteristics of the financial assets. 

Specifically:  

• 

• 

debt instruments that are held within a business model whose objective is to collect the contractual 

cash flows, and that have contractual cash flows that are solely payments of principal and interest on 

the principal amount outstanding, are measured subsequently at amortized cost, and 

all other debt investments and equity investments are measured subsequently at fair value through 

profit or loss (FVTPL). 

The Company applies the IFRS 9 simplified approach to measuring expected credit losses which uses a 

lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade 

receivables have been grouped based on shared credit risk characteristics and the days past due. Trade 

 
 
PAGE 61 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

receivables are written off when there is no reasonable expectation of recovery. Indicators that there is no 

reasonable expectation of recovery include, amongst others, the failure of a debtor to engage in a repayment 

plan with the Company, and a failure to make contractual payments for a period of greater than 120 days 

past due. Impairment losses on trade receivables and contract assets are presented as net impairment losses 

within operating profit. Subsequent recoveries of amounts previously written off are credited against the 

same line item.  

The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset 

expire, or the Company transfers the right to receive the contractual cash flows on the financial asset in a 

transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. 

(m) Cash and cash equivalents  
Cash and cash equivalents include cash on hand and all highly liquid investments with original maturities of 

three months or less that are readily convertible to a known amount of cash and bear an insignificant risk of 

change in value.  

(n) Financial liabilities and equity instruments  
Debt and equity instruments are classified as either financial liabilities or as equity in accordance with the 

substance of the contractual arrangement.  

(i) Equity instruments  

An equity instrument is any contract that evidences a residual interest in the assets of an entity after 

deducting all of its liabilities. Equity instruments issued by the Company are recognized at the proceeds 

received, net of direct issue costs.  

(ii) Compound financial instruments 

Compound financial instruments issued by the Company comprise convertible notes denominated in euro 

that can be converted to share capital at the option of the holder, when the number of shares to be issued is 

fixed and does not vary with changes in fair value.  

The component parts of convertible loan notes issued by the Group are classified separately as financial 

liabilities and equity in accordance with the substance of the contractual arrangements and the definitions of 

a financial liability and an equity instrument. A conversion option that will be settled by the exchange of a 

fixed amount of cash or another financial asset for a fixed number of the Company’s own equity instruments 

is an equity instrument. At the date of issue, the fair value of the liability component is estimated using the 

prevailing market interest rate for a similar non-convertible instrument. This amount is recorded as a liability 

on an amortized cost basis using the effective interest method until extinguished upon conversion or at the 

instrument’s maturity date.  

The conversion option classified as equity is determined by deducting the amount of the liability component 

from the fair value of the compound instrument as a whole. This is recognized and included in equity, net of 

income tax effects, and is not subsequently remeasured. In addition, the conversion option classified as 

equity will remain in equity until the conversion option is exercised, in which case, the balance recognized in 

equity will be transferred to share premium. Where the conversion option remains unexercised at the 

maturity date of the convertible loan note, the balance recognized in equity will be transferred to 

accumulated losses. No gain or loss is recognized in profit or loss upon conversion or expiration of the 

conversion option. 

Transaction costs that relate to the issue of the convertible loan notes are allocated to the liability and equity 

components in proportion to the allocation of the gross proceeds. Transaction costs relating to the equity 

 
 
 
PAGE 62 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

component are recognized directly in equity. Transaction costs relating to the liability component are 

included in the carrying amount of the liability component and are amortized over the lives of the convertible 

loan notes using the effective interest method. 

Interest related to the financial liability is recognized in profit or loss. 

(iii) Financial liabilities at fair value through profit or loss 

Financial liabilities held for trading are classified as at fair value through profit or loss (FVTPL). A financial 

liability is classified as held for trading if it is a derivative (except for a derivative that is a financial guarantee 

contract or a designated and effective hedging instrument). 

Financial liabilities at FVTPL are measured at fair value, with any gains or losses arising on changes in fair 

value recognized in profit or loss. The net gain or loss recognized is included in the ‘results related to financial 

liabilities measured at fair value through profit or loss’ line item in profit or loss. 

Fair value is determined in the manner described in note 5. 

(iv) Other financial liabilities  

Other financial liabilities, including borrowings, are initially measured at fair value, net of transaction costs 

incurred, and are subsequently measured at amortized cost using the effective interest method, with interest 

expense recognized on an effective yield basis.  

The effective interest method is a method of calculating the amortized cost of a financial liability and of 

allocating interest expense over the relevant period. The effective interest rate is the rate that exactly 

discounts estimated future cash payments through the expected life of the financial liability, or, where 

appropriate, a shorter period.  

Borrowings and other financial liabilities are classified as ‘non-current liabilities,’ other than liabilities with 

maturities up to one year, which are classified as “current liabilities”.  

The Company derecognizes financial liabilities when the liability is discharged, cancelled or expired. For all 

financial liabilities, the fair value approximates its carrying amount.  

(v) Offsetting  

Financial assets and financial liabilities are offset and the net amount presented in the statement of financial 

position when, and only when, the Company currently has a legally enforceable right to set off the amounts 

and it intends either to settle them on a net basis or to realise the asset and settle the liability simultaneously. 

(n) Leases 
The Company assesses whether a contract is or contains a lease when it obtains the right to control the use 

of an identified asset for a period of time, in exchange for consideration. The Company recognizes a right-of-

use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, 

except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value 

assets (such as tablets and personal computers, small items of office furniture and telephones). For these 

leases, the Company recognizes the lease payments as operating costs on a straight-line basis over the term 

of the lease unless another systematic basis is more representative of the time pattern in which economic 

benefits from the leased assets are consumed. 

 
 
PAGE 63 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

The lease liability is initially measured at the present value of the lease payments that are not paid at the 

commencement date, discounted by using the interest rate implicit in the lease. When the interest rate 

implicit in the lease cannot be readily determined, the Company uses its incremental borrowing rate. 

Lease payments included in the measurement of the lease liability comprise:  

• 
• 

• 
• 

• 

Fixed lease payments (including in-substance fixed payments), less any lease incentives receivable;  

Variable lease payments that depend on an index or rate, initially measured using the index or rate at 

the commencement date;  

The amount expected to be payable by the Company under residual value guarantees;  

The exercise price of purchase options, if the Company is reasonably certain to exercise the options; 

and  

Payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to 

terminate the lease.  

The lease liability is presented as a separate line in the consolidated statement of financial position. In the 

cash flow statement, repayments of the principal portion of the lease liability are included in financing 

activities. Payments relating to the interest component of the lease liability are included in operating 

activities. Short-term lease payments and payments for leases of low-value assets are included in operating 

activities. 

The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease 

liability (using the effective interest method) and by reducing the carrying amount to reflect the lease 

payments made.  

The Company remeasures the lease liability (and makes a corresponding adjustment to the related right-of-

use asset) whenever:  

• 

• 

• 

The lease term has changed or there is a significant event or change in circumstances resulting in a 

change in the assessment of exercise of a purchase option, in which case the lease liability is 

remeasured by discounting the revised lease payments using a revised discount rate.  

The lease payments change due to changes in an index or rate or a change in expected payment under 

a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised 

lease payments using an unchanged discount rate (unless the lease payments change is due to a 

change in a floating interest rate, in which case a revised discount rate is used).  

A lease contract is modified and the lease modification is not accounted for as a separate lease, in which 

case the lease liability is remeasured based on the lease term of the modified lease by discounting the 

revised lease payments using a revised discount rate at the effective date of the modification.  

The right-of-use asset comprises the initial measurement of the corresponding lease liability, lease payments 

made at or before the commencement day, less any lease incentives received and any initial direct costs. It is 

subsequently measured at cost less accumulated depreciation and impairment losses.  

Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the 

site on which it is located or restore the underlying asset to the condition required by the terms and 

conditions of the lease, a provision is recognized and measured under IAS 37. To the extent that the costs 

relate to a right-of-use asset, the costs are included in the related right-of-use asset, unless those costs are 

incurred to produce inventories. 

 
 
 
PAGE 64 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying 

asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that 

the Company expects to exercise a purchase option, the related right-of-use asset is depreciated over the 

useful life of the underlying asset. The depreciation starts at the commencement date of the lease.  

The right-of-use asset is presented under Property, Plant and Equipment in the consolidated statement of 

financial position, in the category Buildings and leasehold improvements.  

As a practical expedient, IFRS 16 permits a lessee not to separate non-lease components, and instead account 

for any lease and associated non-lease components as a single arrangement. The Company has used this 

practical expedient. 

4. New standards and interpretations not yet adopted 

A number of new standards, amendments to standards and interpretations are effective for annual periods 

beginning after January 1, 2022 and have not been applied in preparing these consolidated financial 

statements. There are no standards that are not yet effective and that would be expected to have a material 

impact on the Company in the current or future reporting periods and on foreseeable future transactions. 

The Company does not plan to adopt these standards early. 

5. Financial Risk Management  

5.1. Financial risk factors 
The Company’s activities expose it to a variety of financial risks: market risk (including currency risk, interest 

rate risk and price risk), credit risk and liquidity risk. The Company’s overall financial risk management seeks 

to minimize potential adverse effects resulting from unpredictability of financial markets on the Company’s 

financial performance.  

Financial risk management is carried out by the finance department. The finance department identifies and 

evaluates financial risks and proposes mitigating actions if deemed appropriate.  

(a) Market risk  

Market risk is the risk that changes in market prices – such as foreign exchange rates, interest rates and 

equity prices – will affect the Company’s income or the value of its holdings of financial instruments. The 

objective of market risk management is to manage and control market risk exposures within acceptable 

parameters, while optimizing the return. 

Foreign exchange risk 

Foreign exchange risk arises from future commercial transactions and recognized assets and liabilities in 

foreign currencies, primarily with respect to the U.S. Dollar. The Company has an exposure associated with 

the time delay between entering into a contract, budget or forecast and the realization thereof. The Company 

operates a foreign exchange policy to manage the foreign exchange risk against the functional currency 

based on the Company’s cash balances and the projected future spend per major currency. 

At year-end, a substantial amount of our cash balances are denominated in U.S. Dollars. This amount reflects 

our current expectation of future expenditure in U.S. dollars. 

At December 31, 2021 there was a net position of assets and liabilities denominated in U.S. dollars of 

€ 32,213,000 (2020: € 22,237,000). Foreign currency denominated receivables and trade payables are short 

term in nature (generally 30 to 45 days). As a result, the foreign exchange results recognized in 2021 and 

2020 are mainly caused by the cash balance denominated in U.S. dollars. 

 
 
PAGE 65 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

A reasonably possible weakening of the U.S. dollar by 10% against the functional currency of the Company at 

December 31, 2021 would have increased our net loss by € 3,221,000 (2020: € 2,224,000). A 10% 

strengthening of the U.S. dollar against the functional current of the Company would have an equal but 

opposite effect on our net loss. The analysis assumes that all other variables, in particular interest rates, 

remain constant. 

Price risk 

The market prices for the production of preclinical and clinical materials and services as well as external 

contracted research may vary over time. Currently, the commercial prices of any of the Company’s product 

candidates is uncertain. When the development products near the regulatory approval date or potential 

regulatory approval date, the uncertainty of the potential sales price decreases. The Company is not exposed 

to commodity price risk.  

Furthermore, the Company does not hold investments designated for sale, therefore are not exposed to 

equity securities price risk.  

Cash flow and fair value Interest rate risk  

The Company’s exposure to interest rate risks is limited due to the use of loans with fixed rates. The 

Company has several loans with fixed interest rates, totaling € 44,090,000 at December 31, 2021 (2020: € 

17,324,000). Details on the interest rates and maturities of these loans are provided in Note 14.  

(b) Credit risk  

Credit risk represents the risk of financial loss caused by default of the counterparty. The Company has no 

large receivables balances with external parties. The Company’s principal financial assets are cash and cash 

equivalents which are held at ABN Amro, Rabobank and Wells Fargo. Our cash management policy is focused 

on preserving capital, providing liquidity for operations and optimizing yield while accepting limited risk 

(Short-term credit ratings must be rated A-1/P-1/F1 at a minimum by at least one of the Nationally 

Recognized Statistical Rating Organizations (NRSROs) specifically Moody’s, Standard & Poor’s or Fitch. Long-

term credit rating must be rated A2 or A at a minimum by at least one NRSRO). 

At December 31, 2021 and December 31, 2020, substantially all of our cash and cash equivalents were held at 

three large institutions, Rabobank, ABN Amro and Wells Fargo. All institutions are highly rated (ratings of Aa3, 

A1 and A2 for Rabobank, ABN Amro and Wells Fargo respectively) with sufficient capital adequacy and 

liquidity metrics. 

There are no financial assets past due date or impaired. No credit limits were exceeded during the reporting 

period. 

(c) Liquidity risk  

Liquidity risk represents the risk that an entity will encounter difficulty in meeting obligations associated with 

its financial liabilities. Prudent liquidity risk management implies ensuring sufficient availability of cash 

resources for funding of operations and planning to raise cash if and when needed, either through issue of 

shares or through credit facilities. Management monitors rolling forecasts of the Company’s liquidity reserve 

on the basis of expected cash flow.  

The table below analyzes ProQR’s undiscounted liabilities into relevant maturity groupings based on the 

remaining period at year-end until the contractual maturity date:

Based on our current operating plan, we believe that the existing cash and cash equivalents will be sufficient 

to fund our anticipated level of operations into 2025. However, our future capital requirements and the 

period for which our existing resources will support our operations may vary significantly from what we 

expect. Our monthly spending levels will vary based on new and ongoing development and corporate 

activities. Because the length of time and activities associated with successful development of our product 

candidates is highly uncertain, we are unable to estimate the actual funds we will require for development of 

our product candidates. 

5.2. Capital risk management 
The Company's objectives when managing capital are to safeguard the Company's ability to continue as a 

going concern in order to provide returns for shareholders, benefits for other stakeholders and to maintain 

an optimal capital structure to reduce the cost of capital. 

In order to maintain or adjust the capital structure, the Company may adjust the amount of dividends paid to 

shareholders (although at this time the Company does not have retained earnings and is therefore currently 

unable to pay dividends), return capital to shareholders, issue new shares or sell assets to reduce debt. 

The total amount of equity as recorded on the balance sheet is managed as capital by the Company. 

5.3. Fair value measurement 
For financial instruments that are measured on the balance sheet at fair value, IFRS 13 requires disclosure of 

fair value measurements by level of the following fair value measurement hierarchy: 

•

Fair value of financial liabilities that are measured at fair value on a recurring basis 

Some of the Company’s financial liabilities are measured at fair value at the end of each reporting period. The 

following table gives information about how the fair values of these financial liabilities are determined (in 

particular, the valuation technique and inputs used).

Valuation technique and key inputs 

Market comparison technique: The valuation model is 
based on market multiples derived from quoted prices 
of companies comparable to the investee, adjusted for 
the effect of the non-marketability of the equity 
securities, and the result of the investee. The estimate is 
adjusted for the net debt of the investee. 

Black-Scholes model. The following variables were 
taken into consideration: current underlying price of the 
Company's shares, options strike price, expected life, 
historical volatility of ProQR share returns over a period 
equal to the expected life, risk-free rate: based on the 
US Treasury yield curve rates per the valuation date 
(interpolated) for the expected life.

multiple were higher (lower). 

None 

Not applicable 

The investment in in Phoenicis Therapeutics, Inc is measured using valuation methods based on so-called 

Level 3 inputs. Level 3 inputs are unobservable inputs. Changing one or more of the unobservable inputs to 

reflect reasonably possible alternative assumptions would not significantly change the fair value determined 

for Phoenicis Therapeutics, Inc. 

Warrants and conversion options are measured using valuation methods based on so-called Level 2 inputs. 

Level 2 inputs are inputs other than quoted prices that are observable for the liability, either directly or 

indirectly. 

The carrying amount of all financial assets and financial liabilities is a reasonable approximation of the fair 

value and therefore information about the fair values of each class has not been disclosed.  

Share options and restricted stock units (RSUs) granted to employees and consultants are measured at the 

fair value of the equity instruments granted. The fair value of options is determined through the use of an 

option-pricing model considering, among others, the following variables:  

• 
• 
• 
• 
• 
• 

the exercise price of the option;  

the expected life of the option;  

the current value of the underlying shares;  

the expected volatility of the share price;  

the dividends expected on the shares; and  

the risk-free interest rate for the life of the option. 

6. Segment Information  

The Company operates in one reportable segment, which comprises the discovery and development of 

innovative, RNA based therapeutics. The management board is identified as the chief operating decision

maker. The management board reviews the operating results regularly to make decisions about resources 

and to assess overall performance. 

Revenues are generated from external customers whose main registered offices are all geographically 

located in the United States. Substantially all non-current assets of the Company are located in the 

Netherlands. The amounts provided to the management board with respect to total assets and liabilities are 

measured in a manner consistent with that of the financial statements.

8. Investments in Associates 

In May 2019, the Company acquired a non-controlling interest in Wings Therapeutics Inc. as part of the 

strategic spin out of the Dystrophic Epidermolysis Bullosa (DEB) activities. Wings Therapeutics Inc. was 

formed and financed by EB Research Partnership (EBRP), the largest global non-profit dedicating to treating 

and curing EB. Wings Therapeutics focuses on developing therapies for DEB and continues to conduct the

ongoing clinical trial with QR-313 targeting exon 73 as well as progress other RNA molecules that are 

designed for other mutations that cause DEB.  

In January 2021, Wings Therapeutics Inc. merged into Phoenicis Therapeutics Inc. Consequently, Wings 

Therapeutics Inc. ceased to exist and the related investment was derecognized. ProQR does not have 

significant influence in Phoenicis Therapeutics Inc. Our interest in Phoenicis is recognized as a financial asset, 

as disclosed in note 9.  

In May 2021, the Company obtained an 8% share in the common stock of Yarrow Biotechnology, Inc. ProQR’s 

share in Yarrow was subsequently diluted to 4.9% in the fourth quarter of 2021, due to Yarrow’s execution of 

a second seed financing round. Although ProQR only owns 4.9% of Yarrow’s shares, the Company has 

significant influence over Yarrow by virtue of its right to appoint one of Yarrow’s three board members, as 

well as its participation in Yarrow’s policy-making process, amongst other factors. As such, our interest in 

Yarrow amounting to € 8,000 at December 31, 2021 is recognized as an investment in associate. 

In 2021, the results related to associates amounting to € 217,000 consist of ProQR's share in the loss of 

Yarrow. In 2020, the results related to associates amount to a loss of € 322,000 and consist of our share of 

the net losses of Wings Therapeutics Inc.

In January 2021, Wings Therapeutics Inc. merged into Phoenicis Therapeutics Inc. by means of a non-cash 

transaction. ProQR holds a 3.9% interest in Phoenicis Therapeutics Inc. In 2021, a gain on disposal of 

associate was recognized amounting to € 514,000, which consists of the fair value of the equity instruments 

received of Phoenicis Therapeutics Inc. of EUR 621,000, partly off-set by the derecognition of the carrying 

value of our investment in Wings Therapeutics, Inc of EUR 107,000.  

The Company elected to recognize subsequent changes in the fair value of our investment in Phoenicis in 

Other Comprehensive Income. There have been no changes in the fair value of our investment in Phoenicis 

since the initial recognition.

The authorized share capital of the Company amounting to € 13,600,000 consists of 170,000,000 ordinary 

shares and 170,000,000 preference shares with a par value of € 0.04 per share. At December 31, 2021, 

74,865,381 ordinary shares were issued. 71,290,805 ordinary shares were fully paid, and 3,574,576 ordinary 

shares were held by the Company as treasury shares (2020: 3,926,743). 

In October 2019, the Company consummated an underwritten public offering of 10,454,545 ordinary shares 

at an issue price of $ 5.50 per share. The gross proceeds from this offering amounted to € 51,597,000 while 

the transaction costs amounted to € 3,047,000, resulting in net proceeds of € 48,550,000. 

In December 2019, the Company issued 371,306 shares in the aggregate amount of $ 3,501,000, at $ 9.43 (€ 

8.51) per share to Ionis Pharmaceuticals, Inc. Under the terms of the agreement, the second installment of 

the upfront payment in ordinary shares to the Company’s common stock was made to Ionis upon the dosing 

of the first patient in the phase 1/2 Aurora clinical trial for QR-1123. 

In March 2020, the Company entered into a sales agreement that permitted the offering, issuance and sale by 

the Company of up to a maximum aggregate offering price of $ 75,000,000 of its ordinary shares that may be 

issued and sold in one or more at-the-market offerings with Citigroup Global Markets, Inc. and Cantor 

Fitzgerald & Co. In January 2021, the Company issued 585,398 ordinary shares under this sales agreement. 

The gross proceeds from this sale amounted to € 2,767,000, with transaction costs amounting to € 114,000, 

resulting in net proceeds of € 2,653,000. In 2020, no shares were issued pursuant to this ATM facility. 

In April 2021, the Company consummated an underwritten public offering of 15,923,077 ordinary shares at 

an issue price of $ 6.50 per share. The gross proceeds from this offering amounted to € 88,115,000 while the 

transaction costs amounted to € 5,499,000, resulting in net proceeds of € 82,616,000. 

In September 2021, the Company issued 3,989,976 shares to Eli Lilly and Company (‘Lilly”) pursuant to the 

global licensing and research collaboration between the Company and Lilly, resulting in gross proceeds of € 

23,223,000, with no significant transaction costs. This amount excludes a premium paid by Eli Lilly that is 

considered to be part of the transaction price of the licensing and research collaboration agreement (refer to 

note 17). 

In November, 2021, the Company filed a shelf registration statement, which permitted: (a) the offering, 

issuance and sale by the Company of up to a maximum aggregate offering price of $ 300,000,000 of its 

ordinary shares, warrants and/or units; and (b) as part of the $ 300,000,000, the offering, issuance and sale by 

us of up to a maximum aggregate offering price of $ 75,000,000 of its ordinary shares that may be issued and

sold under a sales agreement with Cantor Fitzgerald & Co in one or more at-the-market offerings. In 2021, no 

shares were issued pursuant to this ATM facility. 

(b) Equity settled employee benefit reserve  
The costs of share options and RSUs for employees, members of the Supervisory Board and members of the 

Management Board are recognized in the income statement, together with a corresponding increase in 

equity during the vesting period, taking into account (deferral of) corporate income taxes. The accumulated 

expense of share options recognized in the income statement is shown separately in the equity category 

‘equity settled employee benefit reserve’ in the ‘statement of changes in equity’. On September 25, 2017, we 

established a Dutch foundation named Stichting Bewaarneming Aandelen ProQR for holding shares in trust 

for employees, members of the Management Board and members of the Supervisory Board of the Company 

and its group companies who from time to time will exercise options under the Company’s equity incentive 

plans. 

(c) Translation reserve 
The translation reserve comprises all foreign currency differences arising from the translation of the financial 

statements of foreign operations.  

(d) Share options and restricted stock units 
The Company operates an equity-settled share-based compensation plan which was introduced in 2013. 

Options and RSUs may be granted to employees, members of the Supervisory Board, members of the 

Management Board and consultants. The compensation expenses included in operating costs for this plan 

were € 6,216,000 in 2021 (2020: € 7,838,000), of which € 3,636,000 (2020: € 4,423,000) was recorded in 

general and administrative costs and € 2,580,000 (2020: € 3,415,000) was recorded in research and 

development costs based on employee allocation. 

Options granted under this stock option plan are exercisable once vested. Any vesting schedule may be 

attached to the granted options and restricted stock units (RSUs), however the typical vesting period is four 

years (25% after every year). The options expire ten years after date of grant. Options granted under the 

stock option plan are granted at exercise prices which equal either the face value or the fair value of the 

ordinary shares of the Company at the date of the grant.  

The fair value of the options is estimated at the date of grant using the Black-Scholes option-pricing model, 

with on average the following assumptions:  

Risk-free interest rate 

Expected dividend yield 

Expected volatility 

Expected life in years

The resulting weighted average grant date fair value of the options amounted to € 2.58 in 2021 (2020: € 5.01). 

The stock options granted have a 10-year life following the grant date and are assumed to be exercised five 

years from date of grant for all awards.

The fair value of RSUs is determined at the grant date by using the Company’s share price at the grant date. 

The resulting weighted average grant date fair value of the RSUs amounted to € 4.27 in 2021. No RSUs were 

granted in 2020 and 2019.

Innovation credit (“Innovatiekrediet”)  

On June 1, 2012, ProQR was awarded an Innovation credit by the Dutch government, through its agency RVO 

of the Ministry of Economic Affairs, for the Company’s cystic fibrosis program. Amounts were drawn under 

this facility in the course of the years 2013 through 2017. The credit covers 35% of the costs incurred in 

respect of the program up to € 5,000,000. The credit was interest-bearing at a rate of 10% per annum. In June 

2020, ProQR received a final waiver of the full amount of the Innovation credit, including accumulated 

interest. Consequently, the carrying amount of € 8,423,000, including accumulated interest, was recognized in 

other income (under grant income) in 2020. 

On December 10, 2018 ProQR was awarded an Innovation credit for the sepofarsen program. Amounts will 

be drawn under this facility from 2018 through 2022. The credit of € 4,755,000 will be used to conduct the 

Phase 2/3 clinical study and efforts to obtain regulatory and ethical market approval (NDA/MAA) of 

sepofarsen for LCA10, of which € 3,907,000 had been received at December 31, 2021. The credit, including 

accrued interest of 10% per annum, is repayable depending on obtaining market approval.  

The assets which are co-financed with the granted innovation credit are subject to a right of pledge for the 

benefit of RVO. 

Convertible loans 

In July 2020, the Company entered into a convertible debt financing agreement with Pontifax Medison Debt 

Financing. Under the agreement, the Company had access to up to $ 30 million in convertible debt financing 

in three tranches of $ 10 million each that will mature over a 54-month period and have an interest-only 

period of 24 months. One tranche of $ 10 million (€ 8.8 million) had been drawn down as at December 31, 

2021. A second close of the convertible debt financing agreement was completed in August 2020 with Kreos 

Capital. Under the second agreement, the Company had access to up to € 15 million in convertible debt 

financing in three tranches of € 5 million each that will mature over a 54-month period and have an interest-

only period of 24 months. One tranche of € 5 million had been drawn down as at December 31, 2021. 

Pontifax and/or Kreos (the ‘Lenders’) may elect to convert the outstanding loans into ProQR ordinary shares 

at any time prior to repayment at a fixed conversion price of $ 7.88 per share. ProQR also has the ability to 

convert the loans into its ordinary shares, at the same conversion price, if the Company’s stock price reaches 

a pre-determined threshold. In connection with the loan agreement, the Company issued to the Lenders

$ 7.88.   

On December 29, 2021, the Company amended its convertible debt financing agreement with the Lenders. 

Under the amended agreement, at December 31, 2021, the Company had drawn down an additional $ 30 

million (€ 26.5 million) that matures over a 54-month period and has an interest-only period of 33 months. 

The amendment replaces the two undrawn tranches under the original convertible debt financing 

agreements. 

The convertible loans from Pontifax and Kreos bear interest of 8.2% per annum.  

The Lenders may elect to convert the outstanding loans into ProQR ordinary shares at any time prior to 

repayment at a fixed conversion price of $ 11.94 per share. ProQR also has the ability to convert the loans 

into its ordinary shares, at the same conversion price, if the Company’s stock price reaches a pre-determined 

threshold. In connection with the amended loan agreement, the Company issued to the Lenders warrants to 

purchase up to an aggregate of 376,952 shares of its common stock at a fixed exercise price of $ 11.94.  

Pontifax’ conversion option and warrants are accounted for as embedded derivatives and are recognized 

separately from the host contract as financial liabilities at fair value through profit or loss. The host contract is 

recognized at amortized cost. 

The Kreos loan is accounted for as a compound financial instrument. The liability component is recognized at 

amortized cost. The equity component is initially recognized at fair value as option premium on convertible 

loan and will not be subsequently remeasured. Kreos’ warrants are accounted for as embedded derivatives 

and are recognized as financial liabilities at fair value through profit or loss. 

As security for the Pontifax and Kreos convertible loans, the Company has pledged the following items, with 

their respective carrying amounts as at December 31, 2021: cash at banks with a carrying amount of 

€ 187,524,000, other receivables with a carrying amount of € 268,000, investments in associates with a 

carrying amount of € 8,000, leasehold improvements with a carrying amount of € 372,000 and equipment 

with a carrying amount of € 1,432,000. 

Convertible loans amounting to € 2.3 million were issued to Amylon Therapeutics B.V. in 2018 and 2019 and 

are interest-bearing at an average rate of 8% per annum. They are convertible into a variable number of 

ordinary shares within 36 months at the option of the holder or the Company in case financing criteria are 

met. Any unconverted loans become payable on demand after 24 – 36 months in equal quarterly terms.

Eli Lilly 
In September 2021, the Company entered into a global licensing and research collaboration with Eli Lilly and 

Company (‘Eli Lilly’) focused on the discovery, development, and commercialization of potential new 

medicines for genetic disorders in the liver and nervous system. ProQR and Eli Lilly will use ProQR’s 

proprietary Axiomer® RNA editing platform to progress new drug targets toward clinical development and 

commercialization. 

Under the terms of the agreement, ProQR received an upfront payment and equity consideration, and is 

eligible to receive milestone payments and royalties on the net sales of any resulting products. In September 

2021, the Company issued 3,989,976 shares to Eli Lilly, resulting in net proceeds of € 23,223,000. This amount 

included a price premium of € 2,144,000, which was determined to be part of the transaction price and as 

such was initially recognized as deferred revenue. An up-front payment of € 17,651,000 was received in 

October 2021.

With regard to its collaboration with Eli Lilly, the Company concluded as follows: 

• 

• 

• 

There is one single performance obligation under IFRS 15, which is the transfer of a license combined 

with the performance of research and development activities. The Company concluded that the license 

is not capable of being distinct and is not distinct in the context of the contract. 

The transaction price of this agreement currently only includes fixed parts, consisting of an up-front fee 

and an equity component. The agreement also contains variable parts, but those are not yet included in 

the transaction price. Milestone payments will only be included to the extent that it is highly probable 

that a significant reversal in the amount of cumulative revenue recognized will not occur when the 

uncertainty associated with the milestones is subsequently resolved. Sales-based milestones and sales-

based royalties will be included as the underlying sales occur. 

The Company recognizes revenue over time, using an input method that estimates the satisfaction of 

the performance obligation as the percentage of labor hours incurred compared to the total estimated 

labor hours required to complete the promised services. 

Yarrow Biotechnology 
In May 2021, the Company entered into an exclusive worldwide license and discovery collaboration for an 

undisclosed target with Yarrow Biotechnology, Inc. (“Yarrow”). Under the terms of the agreement, ProQR 

received an upfront payment, equity consideration and reimbursement for ongoing R&D services. ProQR is 

also eligible to receive milestone payments and royalties on the net sales of any resulting products. In May 

2021, ProQR received an up-front payment of € 419,000 and 8% of the shares of Yarrow’s common stock (see 

Note 8). In 2021, ProQR also received reimbursements for R&D services performed amounting to € 178,000. 

With regard to its collaboration with Yarrow, the Company concluded as follows: 

• 

• 

There is one single performance obligation under IFRS 15, which is the transfer of a license combined 

with the performance of research and development activities. The Company concluded that the license 

is not capable of being distinct and is not distinct in the context of the contract. 

The transaction price of this agreement currently includes both fixed and variable parts. The fixed part 

consists of an up-front fee and an equity component. The variable part consists of a cost 

reimbursement for research and development activities. The agreement also contains other variable 

parts, but those are not yet included in the transaction price. Milestone payments will only be included 

to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue 

recognized will not occur when the uncertainty associated with the milestones is subsequently resolved. 

Sales-based milestones and sales-based royalties will be included as the underlying sales occur.

was recognized in grant income in 2020. 

On February 9, 2018, the Company entered into a partnership agreement with Foundation Fighting Blindness 

(FFB), under which FFB has agreed to provide funding of $ 7,500,000 for the preclinical and clinical 

development of ultevursen for Usher syndrome type 2A targeting mutations in exon 13. FFB grant income

The Company recognizes deferred tax assets arising from unused tax losses or tax credits only to the extent 

that the Company has sufficient taxable temporary differences or there is convincing evidence that sufficient 

taxable profit will be available against which the unused tax losses or unused tax credits can be utilized. 

Management’s judgment is that such convincing evidence is currently not sufficiently available and a deferred 

tax asset is therefore only recognized to the extent that the Company has sufficient taxable temporary 

differences. Consequently, the Company has not recognized a deferred tax asset related to operating losses.  

As per December 31, 2021, the Company has a total amount of € 312.6 million (2020: € 254.2 million, 2019: € 

218.1 million) tax loss carry-forwards available for offset against future taxable profits, which may be carried 

forward indefinitely. However, the offset of losses will be limited in a given year against the first € 1 million of 

taxable profit. For taxable profit in excess of this amount, losses may only be offset up to 50% of this excess.

(b) Diluted earnings per share  
For the periods included in these financial statements, the share options are not included in the diluted 

earnings per share calculation as the Company was loss-making in all periods. Due to the anti-dilutive nature 

of the outstanding options, basic and diluted earnings per share are equal.  

(c) Dividends per share  
The Company did not declare dividends for any of the years presented in these financial statements.  

25. Leases  

The Company leases office and laboratory facilities of 4,818 square meters at Zernikedreef in Leiden, the 

Netherlands, where our headquarters and our laboratories are located. The current lease agreement for 

these facilities terminates on June 30, 2031. The lease agreement contains no significant dismantling 

requirements.  

The initial 10-year lease agreement for the Leiden office and laboratory facilities was accounted for as of 

commencement date July 1, 2020. This 10-year period was extended by 1 year to an 11-year period in 

December 2020. The lease contract may be extended for subsequent 5-year periods. As the Company is not 

reasonably certain to exercise these extension options, these are not included in the lease term. 

The lease liability and the corresponding right-of-use asset for this lease contract, initially recognized on July 

1, 2020, amounted to € 16,203,000 and € 16,332,000, respectively. A modification to reflect the additional 1 

year lease period resulted in an increase in the carrying amounts of the lease liability and the right-of-use 

asset of € 1,260,000. In June 2021, the lease price was amended to reflect an indexation. The lease liability 

was remeasured, resulting in an increase in the carrying amounts of the lease liability and the right-of-use 

asset of € 415,000. 

In 2021, the Company entered into an agreement to rent research space in London, UK, for a period of two 

years. The lease liability and the corresponding right-of-use asset for this lease contract, initially recognized 

on April 1, 2021, amounted to € 121,000 each.

The carrying amount of the right-of-use asset at the end of the reporting period is disclosed in note 7

A maturity analysis of our lease liability is included in note 5 Financial Risk Management under (c) Liquidity 

risk. The total undiscounted commitment for lease agreements to which the Company had committed at 

December 31, 2021 amounts to € 20,509,000. This amount does not include potential commitments that may 

arise from contractual extension options, as the Company is not reasonably certain that any extension 

options will be exercised.  

26. Commitments and Contingencies  

(a) Claims  
There are no claims known to management related to the activities of the Company.  

(b) Patent license agreements  
On October 26, 2018, the Company and Ionis Pharmaceuticals, Inc. entered into a License Agreement, 

pursuant to which Ionis granted an exclusive, worldwide, royalty-bearing license to us to develop and 

commercialize certain pharmaceutical products, including the product designated by Ionis as IONIS-RHO-

2.5Rx, which has been re-designated by us as QR-1123, for the prevention or treatment of retinitis 

pigmentosa in humans, including patient screening. Ionis also granted to the Company certain sub-license 

rights. Under the License Agreement, we are required to make an upfront payment of an aggregate of up to $ 

6.0 million in installments, and certain payments up to an aggregate of $ 20.0 million upon the satisfaction of 

certain development and sales milestones. In addition, Ionis is entitled to royalty payments in the low double 

digits of aggregate annual net sales, subject to minimum sales in certain circumstances, and subject to 

reduced rates in certain circumstances. The royalty term lasts on a product-by-product and country-by-

country basis, until the later of the expiration of the patent rights licensed to us and the expiration of 

regulatory-based exclusivity for such product in such country. The License Agreement may also be 

terminated by either party based upon certain uncured material breach by, or insolvency of, the other party, 

or by us at any time with advanced notice. In connection with the upfront payments and development 

milestone payments, we also simultaneously entered into a Stock Purchase Agreement with Ionis, pursuant 

to which we agreed to issue an aggregate of $ 2.5 million of ordinary shares to satisfy the first installment 

upfront payment, and the remaining installment of the upfront payment in ordinary shares determined upon 

the due date of such installment. In addition, the Stock Purchase Agreement provides for the ability for us, at 

our discretion, to pay the development milestone payments in ordinary shares when such payments are due. 

We may not issue ordinary shares to Ionis to the extent that such issuance would result in Ionis owning in 

excess of 18.5% of our issued and outstanding shares, nor may we issue ordinary shares if such issuance, 

together with previous issuances under the Stock Purchase Agreement, would exceed 19.9% of our 

outstanding ordinary shares as of the date of the execution of the Stock Purchase Agreement. Under these 

circumstances, we are required to pay the remainder of the upfront and/or development milestone 

payments in cash. In addition, in connection with the Stock Purchase Agreement, we also entered into an 

Investor Agreement with Ionis, pursuant to which we agreed to register for resale the ordinary shares issued

by us under the Stock Purchase Agreement, under the circumstances described in the Investor Agreement. 

The Investor Agreement also contains customary covenants related to our registration of such shares, 

preparation of filings in connection therewith and indemnification of Ionis. The Investor Agreement also 

contains lockup provisions prohibiting the disposition of our ordinary shares issued under the Stock Purchase 

Agreement for a period of 12 months from the applicable issuance date, as well as voting provisions requiring 

Ionis to vote its ordinary shares in accordance with the recommendations of our board of directors, in each 

case subject to certain exceptions.  

In April 2014 the Company entered into a Patent License Agreement with Radboud University Medical Center 

(Radboud) in the field of antisense oligonucleotide-based therapy for Leber’s Congenital Amaurosis (LCA). 

Under the terms of this license agreement, the Company has an exclusive, sublicensable, world-wide royalty-

bearing license under certain Radboud patent rights to develop, make, have made, use, sell, offer for sale and 

import certain licensed products of Radboud for use in all prophylactic and therapeutic uses in the field of 

LCA. Pursuant to the terms of the license agreement, the Company is obligated to pay Radboud net-sales-

related royalties which shall be determined on a product-by-product and country-by-country basis. If the 

Company is required to pay any third party royalties, it may deduct that amount from that which is owed to 

Radboud. Radboud shall provide human resources, materials, facilities and equipment that are necessary for 

preclinical and clinical trials and if the Company does not purchase such trial facilities from Radboud, it is 

required to pay an increased net-sales-related royalty. In the Company’s sole discretion, it may elect to 

convert the obligation to pay net-sales-related royalties into one of the two lump-sum royalty options 

contained in the license agreement, the amount of which depends on whether the Company elects to convert 

prior to or after regulatory approval has been filed. The license agreement will remain in effect until the date 

on which all of the relevant patent applications and all granted patents ensuing from such applications have 

expired or is terminated earlier in accordance with the agreement. Either party may terminate the agreement 

if the other party is in default of a material obligation under the agreement which has not been cured within 

30 days of notice of such default. Either party may also terminate the agreement if the other party declares 

bankruptcy, dissolves, liquidates or is subject to other analogous proceedings. Radboud may also terminate 

the license agreement if the Company does not pay any amount owed under the agreement and such 

payment remains overdue for at least 30 days after receiving notice from Radboud of the amount due. 

In June 2015, the Company entered into another license agreement with Radboud. Under the terms of this 

license agreement, the Company has an exclusive, sublicensable, world-wide royalty-bearing license under 

certain Radboud patent rights to develop, make, have made, use, sell, offer for sale and import certain 

licensed products of Radboud for use in all prophylactic and therapeutic uses in the field of Usher syndrome. 

Pursuant to the terms of the license agreement, the Company is obligated to pay Radboud net-sales-related 

royalties which shall be determined on a product-by-product and country-by-country basis. If the Company is 

required to pay any third party royalties, it may deduct that amount from that which is owed to Radboud. 

Radboud shall provide human resources, materials, facilities and equipment that are necessary for preclinical 

and clinical trials and if the Company does not purchase such trial facilities from Radboud, it is required to 

pay an increased net-sales-related royalty. In the Company’s sole discretion, it may elect to convert the 

obligation to pay net-sales-related royalties into one of the two lump-sum royalty options contained in the 

license agreement, the amount of which depends on whether it elects to convert prior to or after regulatory 

approval has been filed. The license agreement will remain in effect until the date on which all of the relevant 

patent applications and all granted patents ensuing from such applications have expired or is terminated 

earlier in accordance with the agreement. Either party may terminate the agreement if the other party is in 

default of a material obligation under the agreement which has not been cured within 30 days of notice of 

such default. Either party may also terminate the agreement if the other party declares bankruptcy, dissolves, 

liquidates or is subject to other analogous proceedings. Radboud may also terminate the license agreement if 

the Company does not pay any amount owed under the agreement and such payment remains overdue for 

at least 30 days after receiving notice from Radboud of the amount due.

In January 2018, the Company entered into a license agreement with Inserm Transfert SA and Assistance-

Publique-Hôpiteaux de Paris. Under the terms of the agreement, the Company has a world-wide, exclusive, 

royalty-bearing license under patent rights belonging to Inserm Transfert SA and other co-owners to develop, 

have developed, make, have made, use, have used and sell, have sold or otherwise distribute certain licensed 

products related to antisense oligonucleotides for treating LCA and method of treatment claims relating to 

modulation of the splicing of the CEP290 gene product. The Company has the right to grant sublicenses to 

third parties subject to certain limitations such as the sublicensee’s activities not conflicting with the public 

order or ethical obligations of Inserm Transfert SA or any co-owner and not tarnishing the image of Inserm 

Transfert SA or any co-owner. In January 2020, the license agreement with Inserm Transfert SA and 

Assistance-Publique-Hôpiteaux de Paris was amended so as to include a world-wide, non-exclusive, royalty-

bearing license under patent rights belonging to Inserm Transfert SA and other co-owners to develop, have 

developed, make, have made, use, have used and sell, have sold or otherwise distribute certain licensed 

products for us in a method for antisense oligonucleotide-mediated exon skipping in the retina. In partial 

consideration of the rights and licenses granted by the license agreement, the Company is required to pay a 

lumpsum payment and an annual license maintenance fee, as well as to make payments upon the 

completion of certain milestones: completion of a clinical trial more advanced than First in Man, such as a 

phase IIb; and the first marketing authorization or any foreign equivalent for a first product. In further 

consideration of the rights and license granted under the agreement, the Company shall pay to Inserm 

Transfert SA a running royalty on net sales of products sold by us or our sublicensee. Unless terminated 

earlier pursuant to termination provisions of Agreement, the license agreement will remain in effect on a 

country-by-country basis, until the later to occur of the following events (i) the invalidation or expiration of the 

last to expire or to be invalidated patent rights which covers the manufacture, use or sale of the product in 

said country or until the expiration of the exclusive commercialization right granted by a regulatory agency to 

a product as an orphan drug or (ii) five years after the first commercial sale of a product in the country in 

which the product is sold. The agreement may be terminated by either party in the event of an uncured 

breach by the other party. Inserm Transfert SA may terminate the agreement if we become the subject of 

voluntary or involuntary winding-up proceedings or judicial recovery, if the Company or its sublicensees 

interrupt development activities for at least one year, if the Company or its sublicensees interrupt 

commercialization for more than twelve months after the first commercialization in a country, if the Company 

does not commercialize a product within two years following our obtaining of marketing approval in a 

country, or if the Company or our sublicensees do not put a product into commercial use and do not keep 

products reasonably available to the public within twelve years of the effective date of the agreement. 

In January 2016, the Company entered into an agreement with Leiden University Medical Center (LUMC) 

which gives us a world-wide, exclusive, royalty-bearing license in the field of amyloid beta related diseases, 

notably Alzheimer’s disease and HCHWA-D, under certain patent rights of LUMC regarding antisense 

oligonucleotide based therapies. This license agreement contains certain diligence obligations for the 

Company coupled to milestone payments and complements the Company’s intellectual property relating to 

its CNS program. On September 12, 2017, this program was transferred to Amylon Therapeutics B.V., in which 

the Company maintains a majority ownership interest. 

In January 2017, the Company entered into an agreement with LUMC, which gives us a world-wide, exclusive, 

royalty-bearing license in the field of Huntington’s disease, under certain patent rights of LUMC regarding

the Company coupled to milestone payments and complements the Company’s intellectual property relating 

to the HD program. 

In February 2019, the Company entered into an agreement with the University of Rochester, New York, which

rights of University of Rochester. This license agreement contains certain diligence obligations for the 

Company coupled to milestone payments and complements the Company’s intellectual property relating to 

the Axiomer/pseudouridylation program. 

In September 2020, the Company entered into an agreement with Vico Therapeutics B.V., which gives us a 

world-wide, exclusive, royalty-bearing, sublicensable license in the field of the prophylactic and therapeutic 

use of antisense oligonucleotide for the treatment of Fuch’s Endothelial Corneal Dystrophy (FECD) caused by 

a trinucleotide repeat, under certain patent rights of Vico Therapeutics B.V. In partial consideration of the 

rights and licenses granted by the license agreement, the Company is required to make annual maintenance 

payments. Unless terminated earlier in accordance with this the license agreement, the agreement will stay in 

effect until the expiration of all of the licensed patent rights. The license agreement may be terminated by 

either party in the event of an uncured breach by the breaching party. Vico Therapeutics B.V. may terminate 

the license agreement if the Company applies for an order or an order is made declaring the Company 

bankrupt or granting the Company suspension of payments, or a liquidator is appointed for the Company, or 

the Company is dissolved, liquidated, or ceases to carry on all or a substantial part of its business or a 

decision is taken to that effect, or in the event uncured payment defaults. 

(c) Clinical support agreements 
On February 9, 2018, the Company entered into an agreement with Foundation Fighting Blindness (FFB), 

under which FFB will provide funding of $ 7.5 million (€ 6.1 million) to advance QR 421a into the clinic and will 

receive future milestone payments.  

Pursuant to the terms of the agreement, the Company is obligated to make a one-time milestone payment to 

FFB of up to $ 37.5 million (€ 30.6 million), payable in four equal annual installments following the first 

commercial sale of QR 421a, the first of which is due within 60 days following the first commercial sale. The 

Company is also obligated to make a payment to FFB of up to $ 15 million (€ 12.2 million) if it transfers, sells 

or licenses QR 421a other than for certain clinical or development purposes, or if the Company enters into a 

change of control transaction. However, the payment in the previous sentence may be set-off against the $ 

37.5 million milestone payment. Either FFB or the Company may terminate the agreement for cause, which 

includes the Company’s material failure to achieve certain commercialization and development milestones. 

The Company’s payment obligations survive the termination of the agreement. 

(d) Research and development commitments  
The Company has research and development commitments, mainly with CRO’s, amounting to € 27,884,000 at 

December 31, 2021 (2020: € 12,003,000). Of these obligations an amount of € 13,024,000 is due in 2022, the 

remainder is due in 1 to 5 years.

28. Subsequent events  

On February 11, 2022, the Company announced the top-line results from the phase 2/3 Illuminate trial of 

sepofarsen in CEP290-mediated LCA10. The study did not meet its primary endpoint nor any notable 

secondary endpoints. No benefit was observed in either treatment arm versus the sham arm. These 

announced results do not affect the amounts recognized in these financial statements. The potential 

consequences of this event had already been taken into account in determining the liquidity projections 

disclosed in these financial statements. 

On April 13, 2022, the Company announced that it will refocus or suspend certain clinical studies and 

suspend all other inherited retinal disease-related research activities. The Company also announced that it 

will reduce its workforce by approximately 30%. In addition, the Company will accelerate the development of 

the Axiomer RNA base-editing technology platform across multiple therapeutic areas. These developments 

do not affect the financial figures included in these financial statements.

Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

Notes to the Company financial statements for the year ended December 31, 
2021 

29. General 

The company financial statements are part of the 2021 financial statements of ProQR Therapeutics N.V. (the 

‘Company’) and have been prepared in accordance with the legal requirements of Part 9, Book 2 of the 

Netherlands Civil Code. 

With reference to the income statement of the company, use has been made of the exemption pursuant to 

Section 402 of Book 2 of the Netherlands Civil Code. 

For information on risk exposure and risk management, see note 5 to the consolidated financial statements. 

Retrospective correction 
After adoption of the FY 2020 annual report, the Company has concluded that a material amount of 

receivables from group companies should be classified as non-current assets based on their nature, instead 

of as current assets under Prepayments and other receivables. The comparative figures for 2020 have been 

restated to reflect this correction. The retrospective correction does not affect the Company’s net result and 

equity. The following table shows the impact on the company balance sheet for 2020:

30. Principles for the measurement of assets and liabilities and the determination 
of the result 

For setting the principles for the recognition and measurement of assets and liabilities and determination of 

the result for its company financial statements, the Company makes use of the option provided in section 

2:362(8) of the Netherlands Civil Code. This means that the principles for the recognition and measurement 

of assets and liabilities and determination of the result (hereinafter referred to as principles for recognition 

and measurement) of the company financial statements of the Company are the same as those applied for 

the consolidated IFRS financial statements. See page 54 for a description of these principles. 

Participating interests in group companies 
Participating interests in group companies are valued using the equity method, applying the IFRS accounting 

policies endorsed by the European Union. Following the adoption of IFRS 9 by the Company, and our 

interpretation of the Dutch Accounting Standard 100.107A, the Company shall, upon identification of a credit 

loss on an intercompany loan and/or receivable, eliminate the carrying amount of the intercompany loan 

and/or receivable for the value of the identified credit loss.  

Result of participating interests 
The share in the result of participating interests consists of the share of the Company in the result of these 

participating interests. Insofar as gains or losses on transactions involving the transfer of assets and liabilities 

between the Company and its participating interests or between participating interests themselves can be 

considered unrealized, they have not been recognised. 

 
 
 
 
  
 
 
 
 
 
 
 
 
PAGE 96 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

Provisions 
Participating interests with a negative net asset value are valued at nil. This measurement also covers any 

receivables provided to the participating interests that are, in substance, an extension of the net investment. 

In particular, this relates to loans for which settlement is neither planned nor likely to occur in the 

foreseeable future. A share in the profits of the participating interest in subsequent years will only be 

recognised if and to the extent that the cumulative unrecognised share of loss has been absorbed. If the 

Company fully or partially guarantees the debts of the relevant participating interest, or if has the 

constructive obligation to enable the participating interest to pay its debts (for its share therein), then a 

provision is recognised accordingly to the amount of the estimated payments by the Company on behalf of 

the participating interest. 

Corporate income taxes 
ProQR Therapeutics N.V. is the head of the Dutch fiscal unity for corporate income taxes. The Company 

recognizes the portion of corporate income tax that it would owe as an independent taxpayer, taking into 

account the allocation of the advantages of the fiscal unity.

Convertible loans 

In July 2020, the Company entered into a convertible debt financing agreement with Pontifax Medison Debt 

Financing. Under the agreement, the Company had access to up to $ 30 million in convertible debt financing 

in three tranches of $ 10 million each that will mature over a 54-month period and have an interest-only 

period of 24 months. One tranche of $ 10 million had been drawn down as at December 31, 2021. A second 

close of the convertible debt financing agreement was completed in August 2020 with Kreos Capital. Under 

the second agreement, the Company had access to up to € 15 million in convertible debt financing in three 

tranches of € 5 million each that will mature over a 54-month period and have an interest-only period of 24 

months. One tranche of € 5 million had been drawn down as at December 31, 2021. 

Pontifax and/or Kreos (the ‘Lenders’) may elect to convert the outstanding loans into ProQR ordinary shares 

at any time prior to repayment at a fixed conversion price of $ 7.88 per share. ProQR also has the ability to 

convert the loans into its ordinary shares, at the same conversion price, if the Company’s stock price reaches 

a pre-determined threshold. In connection with the loan agreement, the Company issued to the Lenders 

warrants to purchase up to an aggregate of 302,676 shares of its common stock at a fixed exercise price of 

$ 7.88.   

On December 29, 2021, the Company amended its convertible debt financing agreement with the Lenders. 

Under the amended agreement, the Company has drawn down an additional $ 30 million (€ 26.5 million) that 

will mature over a 54-month period and has an interest-only period of 33 months. The amendment replaces 

the two undrawn tranches under the original convertible debt financing agreements. 

The convertible loans from Pontifax and Kreos bear interest of 8.2% per annum. 

The Lenders may elect to convert the outstanding loans into ProQR ordinary shares at any time prior to 

repayment at a fixed conversion price of $ 11.94 per share. ProQR also has the ability to convert the loans 

into its ordinary shares, at the same conversion price, if the Company’s stock price reaches a pre-determined 

threshold. In connection with the amended loan agreement, the Company issued to the Lenders warrants to 

purchase up to an aggregate of 376,952 shares of its common stock at a fixed exercise price of $ 11.94.  

Pontifax’ conversion option and warrants are accounted for as embedded derivatives and are recognized 

separately from the host contract as financial liabilities at fair value through profit or loss. The host contract is 

recognized at amortized cost. 

The Kreos loan is accounted for as a compound financial instrument. The liability component is recognized at 

amortized cost. The equity component is initially recognized at fair value as option premium on convertible 

loan and will not be subsequently remeasured. Kreos’ warrants are accounted for as embedded derivatives 

and are recognized as financial liabilities at fair value through profit or loss. 

As security for the Pontifax and Kreos convertible loans, the Company has pledged the following items, with 

their respective carrying amounts as at December 31, 2021: cash at banks with a carrying amount of 

€ 187,524,000, other receivables with a carrying amount of € 268,000, investments in associates with a 

carrying amount of € 8,000, leasehold improvements with a carrying amount of € 372,000 and equipment 

with a carrying amount of € 1,432,000.

Our opinion 

In our opinion: 
• 

the accompanying consolidated financial statements give a true and fair view of the financial position of 

ProQR Therapeutics N.V. as at December 31, 2021 and of its result and its cash flows for the year then 

ended, in accordance with International Financial Reporting Standards as adopted by the European 

Union (EU-IFRS) and with Part 9 of Book 2 of the Dutch Civil Code.

3. 

the company balance sheet as December 31, 2021; 

the company income statement for 2021; and

Basis for our opinion 

We conducted our audit in accordance with Dutch law, including the Dutch Standards on Auditing. Our 

responsibilities under those standards are further described in the ‘Our responsibilities for the audit of the 

financial statements’ section of our report. 

We are independent of ProQR Therapeutics N.V. in accordance with the ‘Verordening inzake de 

onafhankelijkheid van accountants bij assurance-opdrachten’ (ViO, Code of Ethics for Professional 

Accountants, a regulation with respect to independence) and other relevant independence regulations in the 

Netherlands. Furthermore, we have complied with the ‘Verordening gedrags- en beroepsregels accountants’ 

(VGBA, Dutch Code of Ethics).  

Our audit procedures were determined in the context of our audit of the financial statements as a whole. Our 

observations in respect of going concern, fraud and non-compliance with laws and regulations and the key 

audit matters should be viewed in that context and not as separate opinions or conclusions. 

We believe the audit evidence we have obtained is sufficient and appropriate to provide a basis for our 

opinion.

at EUR 2 million. The materiality is determined with reference to result before corporate income taxes (2.9%). 

We consider the result before corporate income taxes as the most appropriate benchmark because this best 

reflects the nature of the entity being in the pre-clinical and clinical development phase, including both 

operational expenses as well as revenue from collaboration agreements. We have also taken into account 

misstatements and/or possible misstatements that in our opinion are material for the users of the financial 

statements for qualitative reasons.  

We agreed with the Supervisory Board that misstatements identified during our audit in excess of 

EUR 100,000 would be reported to them, as well as smaller misstatements that in our view must be reported 

on qualitative grounds. 

Scope of the group audit 

ProQR Therapeutics N.V. is at the head of a group of components. The financial information of this group is 

included in the financial statements of ProQR Therapeutics N.V. 

The financial administration for all group entities is centralized in the Netherlands. Consequently, we have 

centralized our audit approach and we performed audit procedures ourselves to obtain sufficient and 

appropriate audit evidence about the group’s financial information to provide an opinion about the financial 

statements. 

Audit response to going concern – no significant going concern risks identified  

As explained in Note 2(d) of the financial statements, the management board has performed its going 

concern assessment and has not identified any significant going concern risks. To assess the management 

board’s assessment, we have performed, inter alia, the following procedures:

Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

• 

• 

• 

we considered whether the management board’s assessment of the going concern risks includes all 

relevant information of which we are aware as a result of our audit; 

we analysed the company’s financial and liquidity position as at year-end and compared it to the 

previous financial year as well as expected research and development cash outflows in terms of 

indicators that could identify significant going concern risks; 

we compared the current financial year’s operating loss and the related cash outflows with the expected 

current financial year’s operating loss and cash outflows.  

The outcome of our risk assessment procedures did not give reason to perform additional audit procedures 

on management’s going concern assessment. 

Audit response to the risk of fraud and non-compliance with laws and regulations 

In chapter “Risks of fraud and non-compliance with laws and regulations” of the financial statements, the 

management board describes its procedures in respect of the risk of fraud and non-compliance with laws 

and regulations. 

As part of our audit, we have gained insights into the Company and its business environment, and assessed 

the design and implementation and, where considered appropriate, tested the operating effectiveness of the 

Company’s risk assessment in relation to fraud and non-compliance. Our procedures included, among other 

things, assessing the Company’s code of conduct, whistleblowing procedures, incidents register and its 

procedures to investigate indications of possible fraud and non-compliance. Furthermore, we performed 

relevant inquiries  with management, those charged with governance and other relevant functions, such as 

Legal Counsel. As part of our audit procedures, we: 

• 
• 

inspected and verified the availability to employees of the Company’s code of conduct;  

evaluated correspondence, if any, with supervisory authorities and regulators as well as legal 

confirmation letters; 

In addition, we performed procedures to obtain an understanding of the legal and regulatory frameworks 

that are applicable to the Company and identified the following areas as those most likely to have a material 

effect on the financial statements:  

• 

• 

Pharmaceutical, intellectual property, and information protection laws and regulations (reflecting the 

Company's significant number of patents and research and development expenditures); and 

financial reporting laws and regulations (reflecting the public environment in which the Company is 

operating). 

We, together with our forensics specialists, evaluated the fraud and non-compliance risk factors to consider 

whether those factors indicate a risk of material misstatement in the financial statements.  

We assessed the presumed fraud risk on revenue recognition as irrelevant, because the revenue transactions 

are related to collaboration agreements and are not resulting from commercialization of products. As such, 

the recurring entries related to amortization of deferred upfront payments, milestone payments and 

reimbursement of expenses are limited and non-complex. 

Based on the above and on the relevant presumed risks laid down in the auditing standards, we identified a 

fraud risk with respect to management override of controls  relevant to our audit, and responded as follows: 

 
 
 
 
PAGE 107 / 111 
Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

— Management override of controls (a presumed risk) 

Risk:  
•  Management is in a unique position to manipulate accounting records and prepare fraudulent financial 

statements by overriding controls that otherwise appear to be operating effectively such as the 

estimates relating to determining the fair value attributable to the employee share-based 

compensation.  

Responses:  
•  We evaluated the design and the implementation and, where considered appropriate, tested the 
operating effectiveness of internal controls that mitigate fraud and non-compliance risks, such as 

processes related to journal entries and the allocation of costs between R&D and other categories 

expenses and estimates for share-based compensation.  

•  We paid particular attention to the allocation of various costs between R&D and other categories of 
expenses from the basis that the external users of the Company’s financial statements focus on its 

research and development (R&D). R&D costs consist principally of the costs associated with research 

and development activities, conducting pre-clinical studies and clinical trials and activities related to 

regulatory filings. 

•  We performed a data analysis of high-risk journal entries, such as journal entries that impact the 

general and administrative costs and research and development costs classification, and evaluated key 

estimates and judgments for bias by the Company’s management. Where we identified instances of 

unexpected journal entries or other risks through our data analytics, we performed additional audit 

procedures to address each identified risk, including testing of transactions back to source information. 

•  We incorporated elements of unpredictability in our audit, including varying our selections of samples 

used in control testing.  

Our procedures to address the identified risks of fraud did not result in a key audit matter. We 

communicated our risk assessment, audit responses and results to the Board of Directors and the 

Supervisory Board.  

Our audit procedures did not reveal indications and/or reasonable suspicion of fraud and non-compliance 

that are considered material for our audit. 

Our key audit matters 

Key audit matters are those matters that, in our professional judgement, were of most significance in our 

audit of the financial statements. We have communicated the key audit matters to the Supervisory Board. 

The key audit matters are not a comprehensive reflection of all matters discussed. 

Identification of distinct performance obligations and determining the over-time revenue recognition 

method for a collaboration and license agreement 

Description 

As disclosed in Note 17 to the consolidated financial statements, the Company primarily generates 

collaboration revenue. In September 2021, the Company entered into a global licensing and research 

collaboration with Eli Lilly and Company. As part of the transaction price, ProQR received EUR 17.6M in an 

upfront payment and EUR 2.1M equity premium in connection on the shares issued. ProQR recognizes 

revenue over time based on a pattern that best reflects the satisfaction of the performance obligation.  

We identified the evaluation of the distinct performance obligations identified by the Company and the 

determination of the appropriate method for measuring progress as a key audit matter. Challenging auditor

Financial Statements 2021 
PROQR THERAPEUTICS ANNUAL REPORT 2021 

judgment was required in evaluating the terms and conditions in the agreement to assess the identification 

of distinct performance obligations and to assess the most appropriate method to measure progress towards 

complete satisfaction of the identified performance obligations. 

Our response 

The following are the primary procedures we performed to address this key audit matter: 

•  We evaluated the design, implementation and operating effectiveness of the company’s internal control 
on the identification of distinct performance obligations and the determination of the appropriate 

method to measure progress. 

•  We obtained and read the Lilly agreement and evaluated the terms and conditions of the agreement as 

well as performed inquiries with R&D personnel to assess that the performance obligations within the 

agreement were completely and accurately identified in accordance with the relevant accounting 

guidance, and an appropriate measure of progress has been selected that best depicts the transfer of 

control to the customer. 

Our observation 

Overall, the results of our procedures performed on management’s identification of distinct performance 

obligations and determining the over-time revenue recognition method for the collaboration and license 

agreement with Lilly, and the related disclosures as included in Note 17 to the consolidated financial 

statements, are satisfactory. 

REPORT ON THE OTHER INFORMATION INCLUDED IN THE ANNUAL REPORT 
In addition to the financial statements and our auditor’s report thereon, the annual report contains other 

information. 

Based on the following procedures performed, we conclude that the other information: 

• 
• 

is consistent with the financial statements and does not contain material misstatements; and 

contains the information as required by Part 9 of Book 2 of the Dutch Civil Code for the management 

report and other information. 

We have read the other information. Based on our knowledge and understanding obtained through our audit 

of the financial statements or otherwise, we have considered whether the other information contains 

material misstatements.  

By performing these procedures, we comply with the requirements of Part 9 of Book 2 of the Dutch Civil Code 

and the Dutch Standard 720. The scope of the procedures performed is less than the scope of those 

performed in our audit of the financial statements.  

Management Board is responsible for the preparation of the other information, including the information as 

required by Part 9 of Book 2 of the Dutch Civil Code.

DESCRIPTION OF RESPONSIBILITIES REGARDING THE FINANCIAL STATEMENTS 

Responsibilities of Management Board and the Supervisory Board  for the financial statements 

Management Board is responsible for the preparation and fair presentation of the financial statements in 

accordance with EU-IFRS and Part 9 of Book 2 of the Dutch Civil Code. Furthermore, Management Board is 

responsible for such internal control as management determines is necessary to enable the preparation of 

the financial statements that are free from material misstatement, whether due to fraud or error. In that 

respect Management Board, under supervision of the Supervisory Board, is responsible for the prevention 

and detection of fraud and non-compliance with laws and regulations, including determining measures to 

resolve the consequences of it and to prevent recurrence. 

As part of the preparation of the financial statements, Management Board is responsible for assessing the 

Company’s ability to continue as a going concern. Based on the financial reporting frameworks mentioned, 

Management Board should prepare the financial statements using the going concern basis of accounting 

unless Management Board either intends to liquidate the Company or to cease operations, or has no realistic 

alternative but to do so. Management Board should disclose events and circumstances that may cast 

significant doubt on the company’s ability to continue as a going concern in the financial statements.   

The Supervisory Board is responsible for overseeing the Company’s financial reporting process. 

Our responsibilities for the audit of the financial statements 

Our objective is to plan and perform the audit engagement in a manner that allows us to obtain sufficient 

and appropriate audit evidence for our opinion.  

Our audit has been performed with a high, but not absolute, level of assurance, which means we may not 

detect all material errors and fraud during our audit. 

Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, 

they could reasonably be expected to influence the economic decisions of users taken on the basis of these 

financial statements. The materiality affects the nature, timing and extent of our audit procedures and the 

evaluation of the effect of identified misstatements on our opinion.  

A further description of our responsibilities for the audit of the financial statements is included in the 

appendix of this auditor's report. This description forms part of our auditor’s report.

APPENDIX 

Description of our responsibilities for the audit of the financial statements 

We have exercised professional judgement and have maintained professional scepticism throughout the 

audit, in accordance with Dutch Standards on Auditing, ethical requirements and independence 

requirements. Our audit included among others: 

• 

• 

• 

• 

• 

• 

identifying and assessing the risks of material misstatement of the financial statements, whether due to 

fraud or error, designing and performing audit procedures responsive to those risks, and obtaining 

audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not 

detecting a material misstatement resulting from fraud is higher than the risk resulting from error, as 

fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of 

internal control; 

obtaining an understanding of internal control relevant to the audit in order to design audit procedures 

that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the 

effectiveness of the Company’s internal control; 

evaluating the appropriateness of accounting policies used and the reasonableness of accounting 

estimates and related disclosures made by Management; 

concluding on the appropriateness of Management’s use of the going concern basis of accounting, and 

based on the audit evidence obtained, whether a material uncertainty exists related to events or 

conditions that may cast significant doubt on Company’s ability to continue as a going concern. If we 

conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to 

the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our 

opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s 

report. However, future events or conditions may cause a company to cease to continue as a going 

concern; 

evaluating the overall presentation, structure and content of the financial statements, including the 

disclosures; and 

evaluating whether the financial statements represent the underlying transactions and events in a 

manner that achieves fair presentation. 

In case of a group audit we are, given our ultimate responsibility for the opinion, also responsible for 

directing, supervising and performing the group audit. In this respect we determine the nature and extent of 

the audit procedures to be carried out for group entities. Decisive are the size and/or the risk profile of the 

group entities or operations. On this basis, we select group entities for which an audit or review has to be 

carried out on the complete set of financial information or specific items. 

We are solely responsible for the opinion and therefore responsible to obtain sufficient appropriate audit 

evidence regarding the financial information of the entities or business activities within the group to express 

an opinion on the financial statements. In this respect we are also responsible for directing, supervising and 

performing the group audit.  

We communicate with the Supervisory Board regarding, among other matters, the planned scope and timing 

of the audit and significant audit findings, including any significant findings in internal control that we identify 

during our audit.  

We provide the Supervisory Board with a statement that we have complied with relevant ethical 

requirements regarding independence, and to communicate with them all relationships and other matters 

that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

PROQR THERAPEUTICS ANNUAL REPORT 2021 

From the matters communicated with the Supervisory Board, we determine the key audit matters: those 

matters that were of most significance in the audit of the financial statements. We describe these matters in 

our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in 

extremely rare circumstances, not communicating the matter is in the public interest.
