ProQR Therapeutics N.V.

• Divestment of sepofarsen and ultevursen ophthalmic programs supports ProQR’s strategic focus on Axiomer® RNA editing platform technology and continued advancement of pipeline

• €129 M cash and cash equivalents as of June 30, 2023 providing runway into mid-2026

LEIDEN, Netherlands & CAMBRIDGE, Mass., Aug. 03, 2023 (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 second quarter ended June 30, 2023, and provided a business update.

“As we continue to advance our Axiomer RNA editing platform technology and pipeline with an initial focus on liver-originated diseases, we were very pleased to announce the divestment of our sepofarsen and ultevursen programs to Théa, where they will continue the development of those programs for patients with rare genetic eye disease,” said Daniel A. de Boer, Chief Executive Officer of ProQR. “Over the next several quarters, we anticipate presenting and publishing additional preclinical data including for our first two pipeline programs, AX-0810 for patients suffering from cholestatic diseases and AX-1412 for patients with cardiovascular risk. Along with our preclinical proof of concept data for the platform, a partnership with Eli Lilly, a leading IP position, and cash runway into mid-2026, ProQR is well positioned to execute on our strategy.”

Recent Progress

• In August, ProQR announced it will divest its late-stage ophthalmic assets, sepofarsen and ultevursen, to Théa. Under the terms of the agreement, ProQR will receive an initial payment of €12.5M and will also be eligible for up to €135M in further development, regulatory and commercial payments, as well as additional earn outs up to high teen percentage based on commercial sales in the US and EU. The transaction is expected to close in the third quarter of 2023, subject to the satisfaction of customary closing conditions.

• In July, ProQR presented an overview of its Axiomer RNA editing platform at the RNA Editing Summit in Boston. The presentation described ongoing efforts led by ProQR to put in place effective strategies to increase RNA editing yields of ADARs using chemical modifications and oligonucleotide design. Additionally highlighted was the potential of the Axiomer platform in multiple organs, as well as its applicability for the treatment of liver-originated disorders, including data from preclinical models.

Anticipated Upcoming Events

• Present various platform updates over the next several quarters, including liver NHP data, at scientific conferences, as well as research related to ongoing discovery efforts and pipeline programs.

• Continue to execute on existing partnership with Eli Lilly.

• ProQR may selectively form new partnerships, which could include multi-target discovery alliances, similar to the Company's partnership with Lilly, or product alliances on specific programs.

• ProQR is on track to advance AX-0810 targeting NTCP and AX-1412 targeting B4GALT1 into clinical development in late 2024/early 2025.

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.
