March 12, 2024 -- Arctic Therapeutics ehf, an Icelandic drug development company and partner Nacuity Pharmaceuticals, Inc., a clinical-stage biopharmaceutical company developing treatments for retinitis pigmentosa, cataracts and other diseases caused by oxidative stress, today announced approval by the European Medicines Agency (EMA) for initiation of the first clinical trial evaluating AT-001 (Nacuity’s NPI-001) for the treatment of Hereditary Cystatin C Amyloid Angiopathy (HCCAA) in Iceland. HCCAA is an ultra rare, serious condition characterized by the accumulation of amyloid in the brain's blood vessels, which can lead to cerebral hemorrhage, stroke, and progressive neurological deterioration, including dementia. Current treatment options are severely limited, focusing primarily on symptom management rather than addressing the underlying cause of the disease. AT-001 is a differentiated, purified, prescription-quality, GMP-grade N-acetylcysteine amide (NACA). “EMA's approval paves the way for a comprehensive investigation into the safety and efficacy of a novel therapeutic approach designed to halt or reverse the progression of HCCAA. Our study aims to explore the potential of AT-001 in modifying the disease's course, improving patient outcomes, and ultimately, saving lives,” said Ivar Hakonarson, CEO and co-founder of Arctic. In September 2022, Nacuity and Arctic entered into an exclusive licensing agreement and strategic partnership for the development and commercialization of Nacuity’s NPI-001 under the name AT-001 for HCCAA in Iceland and related forms of amyloid angiopathies (CAAs) worldwide. Nacuity is also currently evaluating NPI-001 in Phase 1/2 clinical trials in Australia for retinitis pigmentosa associated with Usher syndrome and cystinosis. “Our proprietary NPI-001 has potential to address the myriad diseases and conditions where oxidative stress plays a role. EMA approval for the evaluation of NPI-001 tablets for treatment of HCCAA represents most importantly, a step forward in addressing HCCAA, a life threatening and underserved rare disease, and secondly, a key pharmaceutical quality milestone for the companies in the global development of NPI-001,” said G. Michael Wall, Ph.D., SVP & CSO, Nacuity. Nacuity Pharmaceuticals, Inc. (http://www.nacuity.com/), is a clinical-stage leader in innovative treatments for oxidative stress. The company’s powerful, targeted therapies aim to attentuate oxidative tissue damage, a driver of blinding eye diseases and a broad spectrum of serious chronic conditions.

Preclinical and translational pipeline program data for AX-0810 for Cholestatic Diseases targeting NTCP and AX-1412 for Cardiovascular Disease targeting B4GALT1 anticipated in 2024, building further momentum toward the clinicAccelerated development of Axiomer™ for CNS applications via new research partnership with Rett Syndrome Research TrustCompleted divestment of sepofarsen and ultevursen ophthalmic programs to Laboratoires Théa€118.9 million cash and cash equivalents as of December 31, 2023 providing runway into mid-2026 LEIDEN, Netherlands & CAMBRIDGE, Mass., March 13, 2024 (GLOBE NEWSWIRE) -- ProQR Therapeutics NV. (Nasdaq: PRQR) (ProQR), a company dedicated to changing lives through transformative RNA therapies based on its proprietary Axiomer™ RNA editing technology platform, today reported its financial and operating results for the year ended December 31, 2023, and provided a business update. “Over the past year as we exclusively focused our strategy on RNA editing, ProQR made important progress with Axiomer, our ADAR-mediated RNA editing technology platform,” said Daniel A. de Boer, Chief Executive Officer of ProQR. “We announced our initial pipeline programs, AX-0810 and AX-1412, targeting NTCP and B4GALT1, respectively, and presented preclinical platform data across a variety of targets. Our platform has demonstrated robust editing, including reporting up to 70% editing of ACTB in the liver of non-human primates, as well as functional protein data with the liver target ANGPTL3 in mice. Additionally, we further strengthened our leading global IP estate for ADAR-mediated RNA editing, which was upheld when challenged by multiple parties in various jurisdictions. We continued to execute and build on the successes achieved during the first two years of our collaboration with Eli Lilly, and formed a new partnership with the Rett Syndrome Research Trust. We also completed the divestment of late-stage ophthalmic assets, sepofarsen and ultevursen, to Laboratoires Théa who will continue the development of these therapies for patients, as ProQR continues to focus exclusively on advancing our RNA editing platform and pipeline.” De Boer continued, “In 2024, we anticipate sharing in vitro, in vivo, and translational data for our initial pipeline programs using Axiomer, and remain on track to enter the clinic in late 2024/early 2025. Along with our extensive body of preclinical proof of concept data for the platform, partnership with Eli Lilly, leading IP position, and strong cash position providing runway into mid-2026, we believe that ProQR is well positioned to continue to execute on our strategy and advance our mission of changing lives through transformative RNA therapies.” Recent Progress In February, ProQR announced that it further strengthened its leading intellectual property estate for ADAR-mediated RNA editing by successfully defending against an opposition filed in Japan by a strawman against ProQR’s granted patent JP 7244922, which is related to the broad concept of using chemically modified oligonucleotides to target specific adenosines within target RNA using endogenous enzymes. The Japanese Patent Office rejected the strawman’s opposition and indicated that all claims were to be maintained as granted to ProQR.In January, ProQR highlighted its continued progress in advancing its Axiomer™ RNA editing technology platform, with new data presented at the 5th International Conference on Base Editing, Prime Editing & Related Enzymes (Deaminet 2024), including: Platform demonstrates robust in vivo editing capabilities reporting up to 70% editing of ACTB in the liver of non-human primates (NHPs) and mice; andFunctional effect demonstrated in mice in vivo via modulation of ANGPLT3 protein properties leading to favorable increase in LPL enzymatic activity and meaningful impact of biomarkers. In January, ProQR and the Rett Syndrome Research Trust (RSRT) formed a partnership focused on utilizing ProQR’s Axiomer™ RNA editing technology platform to design and develop editing oligonucleotides targeting an underlying genetic variant that causes Rett syndrome. RSRT awarded ProQR approximately $1 million as a research grant for the initial phase of the project, which encompasses editing oligonucleotide design and optimization, including evaluation in in vivo models for editing efficiency and MECP2 protein recovery. It is the intent of the partnership to be continued by an expanded co-funding arrangement following the initial discovery work.In December, ProQR completed the divestment of sepofarsen and ultevursen to Laboratoires Théa, who will continue the development of these programs for patients with LCA10 and Usher syndrome. The transaction agreement provided ProQR with an initial payment of €8 million and the Company may be eligible for up to €165 million in further development, regulatory, and commercial earn-out payments upon related achieved milestones, as well as double-digit royalties based on commercial sales in the US and EU.

About Axiomer™ ProQR is pioneering a next-generation RNA base editing technology called Axiomer™, which could potentially yield a new class of medicines for diverse types of 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 called ADAR (Adenosine Deaminase Acting on RNA). Axiomer™ EONs are designed to recruit and direct endogenously expressed ADARs to change an Adenosine (A) to an Inosine (I) in the RNA – an Inosine is translated as a Guanosine (G) – correcting an RNA with a disease-causing mutation back to a normal (wild type) RNA, modulating protein expression, or altering a protein so that it will have a new function that helps prevent or treat disease. About Biliary Atresia (BA) and Primary Sclerosing Cholangitis (PSC) Cholestatic disorders refer to a group of diseases presenting excessive and toxic buildup of bile acids in the liver due to bile ducts dysfunction. This leads to liver damage and a range of debilitating symptoms. Without treatment, liver damage can progress through various stages, ultimately leading to liver failure and elevated risk of liver malignancy, affecting life expectancy. Cholestatic diseases remain leading causes of liver transplantation. There are no approved therapies for primary sclerosing cholangitis (PSC) for adults and biliary atresia (BA) for pediatrics It is estimated that 80,000 and 20,000 individuals have PSC and BA, respectively, in North America and in Europe. About AX-0810 targeting NTCP The majority of the bile acids present in the liver cells originate from the enterohepatic reuptake cycle. The key transporter responsible for hepatic uptake of bile acids from portal circulation is the sodium (Na+)-taurocholate cotransporting polypeptide (NTCP, SLC10A1 gene) expressed in the liver. AX-0810 is designed to introduce a loss of function variant in SLC10A1 RNA that has been found in human genetics to prevent re-uptake of bile acids in liver via NTCP. Based on its mechanism of action, AX-0810 has the potential to become a disease modifying treatment for PSC and BA primarily among other cholestatic diseases. About Cardiovascular Diseases Cardiovascular diseases (CVDs) are a group of health conditions that affect the heart and blood vessels, such as atherosclerosis which can lead to severe problems like heart attacks, heart failure, and stroke. CVDs represent the leading cause of disability and death in the world. Approximately 18 million people die every year from CVDs representing one third of all the global deaths. Despite available lipid lowering therapies and hypertension medications, the risk of CVDs is still projected to increase rapidly over the coming years. About AX-1412 targeting B4GALT1 Gene–based analysis of rare beta-1,4-galactosyltransferase 1 (B4GALT1) missense variant (p.Asn352Ser) is known to lead to B4GALT1 protein loss of function and showed an association with decreased coronary artery disease. These beneficial effects are mediated by hypo-galactosylation of the apolipoprotein B100 and fibrinogen, known – independent – drivers of increased risk of CVDs. AX-1412 introduces a protective variant into B4GALT1 RNA to address the remaining residual risk of developing cardiovascular diseases. ProQR intends to advance AX-1412 targeting B4GALT1 to early clinical proof of concept stage, then would seek to partner this program. 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 both rare and prevalent diseases with unmet need. 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.
