ProQR Announces First Quarter 2022 Operating and Financial Results

Post-hoc analyses from Illuminate trial of sepofarsen demonstrate an encouraging efficacy signal when comparing active treatment and sham eyes to their corresponding contralateral eyes across multiple endpoints – Company plans to discuss findings with regulators and provide an update in Q3/early Q4Enrollment is ongoing in Sirius, a Phase 2/3 trial of ultevursen (QR-421a), for USH2A-mediated Usher syndrome and retinitis pigmentosaProQR is accelerating the development of its Axiomer® RNA base-editing technology platform across multiple therapeutic areas and will provide an update on first targets in H2 2022Cash runway into 2025 LEIDEN, Netherlands & CAMBRIDGE, Mass., May 05, 2022 (GLOBE NEWSWIRE) —  ProQR Therapeutics N.V. (Nasdaq: PRQR) (the “Company”), a company dedicated to changing lives through the creation of transformative RNA therapies, today reported its financial and operating results for the first quarter ended March 31, 2022, and provided a business update. “In April, we took important steps toward focusing our strategy on accelerating our Axiomer RNA-base editing platform technology, and a select pipeline of RNA therapies for inherited retinal diseases,” said Daniel A. de Boer, Founder and CEO of ProQR Therapeutics. “While we were disappointed by the outcome of the primary analysis in the Illuminate trial of sepofarsen, we believe that the post-hoc analyses and the observation that approximately a third of the patients benefited across multiple concordant endpoints in this trial, in combination with the high unmet need for those with LCA10, warrants a discussion with the regulators. We plan to meet with the regulators in Q3 and will share an update in Q3 or early Q4, depending on timing of the meetings. Additionally, we look forward to sharing details of our development plans for Axiomer in the second half of 2022. ProQR has a strong cash position with runway into 2025, and we look forward to continued progress with the business.” Business Operations and Program Updates Program updates In April, the Company announced that post-hoc analyses from Illuminate trial of sepofarsen demonstrate an encouraging efficacy signal when comparing active treatment and sham eyes to their corresponding contralateral eyes across multiple endpoints. In Q3, the Company plans to meet with the EMA and FDA to discuss these data from the Illuminate trial. Following this discussion, ProQR will share an update in Q3 or early Q4, depending on timing of regulatory meetings. Findings from Illuminate, including examples of individual patient data, were 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.Based on the recommendation of the sepofarsen Data Safety and Monitoring Committee (DSMC), the Company currently plans to continue Illuminate, which is a 2 year study, the Brighten pediatric study, and Insight, until further regulatory guidance, after which next steps will be determined.Enrollment is ongoing in Sirius, a Phase 2/3 trial of ultevursen (QR-421a), for USH2A-mediated Usher syndrome and retinitis pigmentosa.ProQR is accelerating the development of its Axiomer RNA editing platform and pipeline activities and plans to expand into areas beyond the eye, including initially liver and CNS, which have strong alignment with ProQR’s oligonucleotide delivery approaches. The Company will present further non-clinical data for Axiomer and announce its internal development targets in H2 2022.In April, the Company presented its proprietary RNA base-editing Axiomer technology at the 3rd RNA Editing Summit. Business updates In March, John Maraganore, PhD, was appointed as a strategic advisor to ProQR’s Supervisory Board. Dr. Maraganore is a biopharma industry veteran and the former founding CEO of Alnylam Pharmaceuticals. In April, the Company announced portfolio prioritization and restructuring initiatives expected to extend ProQR’s cash runway into 2025. On May 3, 2022 the Company received written notification from Nasdaq that for the last 30 consecutive business days the Company’s ordinary shares did not maintain a minimum closing bid price of $1.00 per share as required by Nasdaq Listing Rule 5550(a)(2). This notice does not result in the immediate delisting of the Company’s ordinary shares from The Nasdaq Global Market. In accordance with Nasdaq Listing Rule 5810(c)(3)(A) (the “Compliance Period Rule”), the Company has been provided an initial period of 180 calendar days, or until October 31, 2022, to regain compliance. If, at any time during this 180-day period, the closing bid price for the Company’s ordinary shares closes at $1.00 or more per share for a minimum of 10 consecutive business days, Nasdaq will provide written compliance notification and the ordinary shares will continue to be eligible for listing on The Nasdaq Global Market. In the event the Company does not regain compliance in the required timeframe, the Company may be eligible for an additional 180 calendar day compliance period. The Company’s business operations are not affected by the receipt of this notification.

About Leber Congenital Amaurosis 10 (LCA10) Leber congenital amaurosis (LCA) is the most common cause of blindness due to genetic disease in children. It consists of a group of diseases of which LCA10 is the most frequent and one of the most severe forms. LCA10 is caused by mutations in the CEP290 gene, of which the c.2991+1655A>G (p.Cys998X) mutation has the highest prevalence. LCA10 leads to early loss of vision causing most people to lose their sight in the first few years of life. To date, there are no treatments approved that treat the underlying cause of the disease. Approximately 2,000 people in the Western world have LCA10 because of this mutation. About sepofarsen Sepofarsen (QR-110) is an investigational RNA therapy designed to restore vision in Leber congenital amaurosis 10 due to the c.2991+1655A>G mutation (p.Cys998X) in the CEP290 gene. The mutation leads to aberrant splicing of the mRNA and non-functional CEP290 protein. Sepofarsen is designed to enable normal splicing, resulting in restoration of normal (wild type) CEP290 mRNA and subsequent production of functional CEP290 protein. Sepofarsen is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the United States and the European Union and received fast-track designation and rare pediatric disease designation from the FDA as well as access to the PRIME scheme by the EMA. About Usher syndrome type 2a and retinitis pigmentosa Usher syndrome is the leading cause of combined deafness and blindness. People with Usher syndrome type 2a are usually born with hearing loss and start to have progressive vision loss during adulthood. The vision loss can also occur without hearing loss in a disease called non-syndromic retinitis pigmentosa. Usher syndrome type 2a and non-syndromic retinitis pigmentosa can be caused by mutations in the USH2A gene. To date, there are no pharmaceutical treatments approved or in clinical development that treat the vision loss associated with mutations in USH2A. About ultevursen Ultevursen (formerly QR-421a) is a first-in-class investigational RNA therapy designed to address the underlying cause of vision loss in Usher syndrome type 2a and non-syndromic retinitis pigmentosa due to mutations in exon 13 of the USH2A gene. QR-421a is designed to restore functional usherin protein by using an exon skipping approach with the aim to stop or reverse vision loss in patients. Ultevursen is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the US and the European Union and received fast-track and rare pediatric disease designations from the FDA. About Axiomer® technology ProQR is pioneering a next-generation RNA technology called Axiomer®, which could potentially yield a new class of medicines for genetic diseases. Axiomer “Editing Oligonucleotides”, or EONs, mediate single nucleotide changes to RNA in a highly specific and targeted way using molecular machinery that is present in human cells. The Axiomer EONs are designed to recruit an endogenously expressed RNA editing system called ADAR, which can direct the change of an Adenosine (A) to an Inosine (I) in the RNA – an Inosine is translated as a Guanosine (G). About ProQR ProQR Therapeutics is dedicated to changing lives through the creation of transformative RNA therapies. ProQR is pioneering a next-generation RNA technology called Axiomer®, which uses a cell’s own editing machinery called ADAR to make specific single nucleotide edits in RNA to reverse a mutation or modulate protein expression and could potentially yield a new class of medicines for genetic diseases. Based on our unique proprietary RNA repair platform technologies we are growing our pipeline with patients and loved ones in mind. Learn more about ProQR at www.proqr.com.
