PROQR THERAPEUTICS N.V.
Notes to Unaudited Condensed Consolidated Financial Statements

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 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. The address of its headquarters and registered office is Zernikedreef 9, 2333 CK Leiden, the Netherlands.

ProQR Therapeutics N.V. is the ultimate parent company of the following entities:

​

ProQR Therapeutics N.V. is also statutory director of Stichting Bewaarneming Aandelen ProQR (“ESOP Foundation”) and has full control over this entity. ProQR Therapeutics N.V. holds a 20% minority shareholding in Wings Therapeutics Inc.

As used in these condensed consolidated financial statements, unless the context indicates otherwise, all references to “ProQR” or the “Company” refer to ProQR Therapeutics N.V. including its subsidiaries and the ESOP Foundation.

2. Significant Accounting Policies

These condensed consolidated financial statements have been prepared in accordance with IAS 34 - Interim Financial Reporting. Certain information and disclosures normally included in financial statements prepared in accordance with IFRS have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s annual financial statements for the year ended December 31, 2019. In the opinion of management, all adjustments, consisting of normal recurring nature, considered necessary for a fair presentation have been included in the condensed consolidated financial statements.

The Company’s financial results have varied substantially, and are expected to continue to vary, from period to period. The Company believes that its ordinary activities are not linked to any particular seasonal factors.

​

​

​

The Company operates in one reportable segment, which comprises the discovery and development of innovative, RNA based therapeutics.

3. Adoption of new and revised International Financial Reporting Standards

The accounting policies adopted in the preparation of the condensed consolidated financial statements are consistent with those applied in the preparation of the Company’s annual financial statements for the year ended December 31, 2019.

New Standards and Interpretations, which became effective as of January 1, 2020, did not have a material impact on our condensed consolidated financial statements.

4. Critical Accounting Estimates and Judgments

In the application of the Company’s accounting policies, management is required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The 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.

Research and development expenditures

Research expenditures are currently not capitalized but are 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.

5. Cash and Cash Equivalents

At December 31, 2020, the Company’s cash and equivalents were € 75,838,000 as compared to € 111,950,000 at December 31, 2019. The cash balances are held at banks with investment grade credit ratings. The cash at banks is at full disposal of the Company.

6. Property, plant and equipment

At December 31, 2020 and December 31, 2019, property plant and equipment consisted of buildings and leasehold improvements, laboratory equipment and other assets. Buildings and leasehold improvements include a right-of-use asset relating to the lease of our Leiden office and laboratory space, with a carrying amount of € 16,775,000 at December 31, 2020 (December 31, 2019: € 606,000).

​

7. Current liabilities

At December 31, 2020 and December 31, 2019, the other current liabilities consisted principally of accruals for services provided by vendors not yet billed, payroll related accruals and other miscellaneous liabilities.

8. Borrowings

​

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 covered 35% of the costs incurred in respect of the program up to € 5.0 million. 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 € 8.4 million, including accumulated interest, was recognized in Other Income (under Grant Income) in the second quarter of 2020.

​

On December 10, 2018 ProQR was awarded an Innovation credit for the sepofarsen program for LCA 10. Amounts will be drawn under this facility from 2018 through 2022. The total credit of € 4.7 million will be used to conduct the Phase 2/3 clinical study for sepofarsen and to finance efforts to obtain regulatory and ethical market approval (NDA/MAA). The credit, including accrued interest of 10% per annum, is repayable depending on ProQR obtaining market approval for sepofarsen. An amount of € 2.8 million had been received as at December 31, 2020. Accumulated interest amounted to € 0.3 million as at December 31, 2020. The assets that are co-financed with the granted innovation credit are subject to a right of pledge for the benefit of RVO.

​

Convertible loans

On July 14, 2020, the Company entered into a convertible debt financing agreement with Pontifax Medison Debt Financing. Under the agreement, the Company will have 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, 2020. A second close of the convertible debt financing agreement was completed on August 6, 2020 with Kreos Capital. Under the second agreement, the Company will have 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, 2020.

Pontifax and/or Kreos may elect to convert the outstanding loans into ProQR ordinary shares at any time prior to repayment at a fixed conversion price. 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 Pontifax and Kreos warrants to purchase up to an aggregate of 302,676 shares of its common stock at a fixed exercise price.

ProQR Announces Fourth Quarter and Full Year 2020 Operating and Financial Results

LEIDEN, Netherlands & CAMBRIDGE, Mass., February 25, 2021 -- ProQR Therapeutics N.V. (Nasdaq: PRQR) (the “Company”), a company dedicated to changing lives through the creation of transformative RNA therapies for inherited retinal diseases (IRDs), today reported its financial and operating results for the fourth quarter and full year ended December 31, 2020 and provided a business update.

“During 2020, we made progress across our pipeline, capped off with completing enrollment in our pivotal trial of sepofarsen for LCA10 last month,” said Daniel A. de Boer, Founder and CEO of ProQR. “On the basis of this performance, we begin 2021 in a strong position to deliver on a number of important catalysts across our pipeline, including the next interim analysis for QR-421a for Usher syndrome and non-syndromic retinitis pigmentosa, which is on track for late Q1/early Q2. With the findings from this IA, in addition to confirming the safety profile and biological activity, we expect to be able to clearly inform the design of the next study of QR-421a, including the dose to take forward, population to enrich for, and endpoint selection. In the year ahead, we also plan to share the first clinical data from QR-1123 for adRP, data from the Phase 1/2 extension study of sepofarsen, and to start dosing patients with QR-504a for FECD.”

De Boer continued, “In 2020, we also advanced the business operationally on several fronts. We strengthened our Scientific Advisory Board with the addition of leading experts in IRDs and RNA therapies. Naveed Shams, MD, PhD, a proven leader with deep ophthalmology experience including multiple product approvals globally, joined us as Chief Scientific Officer. And, we extended our cash runway into 2023 through a strategic convertible debt facility, increasing our financial flexibility as we continue to advance our pipeline and build toward commercialization.”

About Leber Congenital Amaurosis 10 (LCA10)

Leber congenital amaurosis (LCA) is the most common cause of blindness due to genetic disease in children. It consists of a group of diseases of which LCA10 is the most frequent and one of the most severe forms. LCA10 is caused by mutations in the CEP290 gene, of which the p.Cys998X mutation has the highest prevalence. LCA10 leads to early loss of vision causing most people to lose their sight in the first few years of life. To date, there are no treatments approved that treat the underlying cause of the disease. Approximately 2,000 people in the Western world have LCA10 because of this mutation.

About Sepofarsen

Sepofarsen (QR-110) is being evaluated in the pivotal Phase 2/3 Illuminate trial and is a first-in-class investigational RNA therapy designed to address the underlying cause of Leber congenital amaurosis 10 due to the p.Cys998X mutation (also known as the c.2991+1655A>G mutation) in

​

​

the CEP290 gene. The p.Cys998X mutation leads to aberrant splicing of the mRNA and non-functional CEP290 protein. Sepofarsen is designed to enable normal splicing, resulting in restoration of normal (wild type) CEP290 mRNA and subsequent production of functional CEP290 protein. Sepofarsen is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the United States and the European Union and received fast-track designation and rare pediatric disease designation from the FDA as well as access to the PRIME scheme by the EMA.

About Usher Syndrome Type 2 and Non-Syndromic Retinitis Pigmentosa

Usher syndrome is the leading cause of combined deafness and blindness. People with Usher syndrome type 2 are usually born with hearing loss and start to have progressive vision loss during adulthood. The vision loss can also occur without hearing loss in a disease called non-syndromic retinitis pigmentosa. Usher syndrome type 2 and non-syndromic retinitis pigmentosa can be caused by mutations in the USH2A gene. To date, there are no pharmaceutical treatments approved or in clinical development that treat the vision loss associated with mutations in USH2A.

About QR-421a

QR-421a is being evaluated in the Phase 1/2 Stellar trial and is a first-in-class investigational RNA therapy designed to address the underlying cause of vision loss in Usher syndrome type 2a and non-syndromic retinitis pigmentosa (RP) due to mutations in exon 13 of the USH2A gene. QR-421a is designed to restore functional usherin protein by using an exon skipping approach with the aim to stop or reverse vision loss in patients. QR-421a is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the US and the European Union and received fast-track and rare pediatric disease designations from the FDA.

About Autosomal Dominant Retinitis Pigmentosa (adRP)

Autosomal dominant retinitis pigmentosa, or adRP, is a severe and rare genetic disease that causes progressive problems in night vision during childhood, leading to visual field loss and frequently resulting in blindness in mid adulthood. In the United States, the most prevalent mutation associated with adRP is the P23H point mutation (also known as the c.68C>A mutation) in the rhodopsin (RHO) gene and affects approximately 2,500 people. This mutation causes misfolding of the rhodopsin protein that becomes toxic to the photoreceptor cells and at the same time diminishes the function of the wild type allele. Over time this results in cell death and progressive vision loss. There are currently no therapies approved or in clinical development for P23H adRP. A natural history study in patients with P23H adRP has been conducted.

​

​

About QR-1123

QR-1123 is being evaluated in the Phase 1/2 Aurora trial and is a first-in-class investigational RNA therapy designed to treat adRP due to the P23H mutation in the RHO gene. QR-1123 was discovered and developed by Ionis Pharmaceuticals using Ionis’ proprietary antisense technology. The therapy aims to inhibit the formation of the mutated toxic version of the rhodopsin protein by specifically binding the mutated RHO mRNA. Binding of QR-1123 causes allele specific knockdown of the mutant mRNA by a mechanism called RNase H mediated cleavage without affecting the normal RHO mRNA. QR-1123 is intended to be administered through intravitreal injections in the eye. QR-1123 was in-licensed from Ionis Pharmaceuticals in 2018. QR-1123 has been granted Orphan Drug designation in the United States and received Fast Track designation from the FDA.

About Fuchs Endothelial Corneal Dystrophy (FECD)

Fuchs endothelial corneal dystrophy (FECD) is a common inherited condition characterized by the dysfunction and degeneration of the corneal endothelium, a single cell layer of cells on the inside of the cornea. FECD is a common disorder; it is estimated that FECD affects more than 4% of individuals over the age of 40 in the U.S., and similar prevalence is noted for other global regions. There are different types of this disease and we focus on age-related FECD Type 3 (FECD3). Some patients with age-related FECD develop advanced disease with corneal edema and corneal clouding. These symptoms can lead to complete vision loss and the need for surgery such as a corneal transplant.

About QR-504a

We are developing QR-504a as an RNA therapy for the treatment of FECD3. We plan to advance the QR-504a program into a first-in-human clinical trial in late-stage disease patients in 2021. QR-504a is designed to target the intronic TNRs in the TCF4 RNA. The aim is to reduce aggregation and the formation of RNA foci in order to normalize the RNA splicing patterns, and prevent or halt corneal degeneration in patients with FECD3.

About ProQR

Given these risks, uncertainties and other factors, you should not place undue reliance on these forward-looking statements, and we assume no obligation to

update these forward-looking statements, even if new information becomes available in the future, except as required by law.
