Given Company's Evolution Milestones

Given Company's Transformative Moments

The most defintely transformative moment for ProQR Therapeutics N.V. was the strategic shift announced in August 2022. This wasn't a minor adjustment; it was a complete overhaul of the company's focus and resource allocation.

• The Great Pivot: Following disappointing feedback from the European Medicines Agency (EMA) on the lead program, sepofarsen (QR-110), the company made the tough, but necessary, decision to stop all clinical trials for its inherited retinal disease assets.
• Axiomer Focus: This move allowed ProQR Therapeutics N.V. to focus its entire strategy and resources on its proprietary Axiomer RNA editing technology, a platform designed to make single nucleotide changes to RNA to correct or modulate protein function.
• Cash Runway Extension: By winding down the expensive, late-stage ophthalmology trials and implementing a workforce reduction, the company was able to extend its cash runway into mid-2026, which was later extended into mid-2027 through strategic financing and partnerships.
• Financial Reality Check: The cost of this focus is clear in the 2025 financials. For the nine months ended September 30, 2025, the company reported a net loss of €33.3 million, which is expected given the ramp-up in Research and Development (R&D) costs to €34.8 million for the same period.
• Clinical Validation: The October 2025 CTA authorization for AX-0810, the first Axiomer editing oligonucleotide (EON) to enter the clinic, is the first major proof point for this new strategy. Initial safety data from this Phase 1 trial in healthy volunteers is expected before the end of 2025.

This history shows a company that faced a clinical setback and, instead of folding, doubled down on its most innovative technology.

ProQR Therapeutics N.V. (PRQR) How It Works

ProQR Therapeutics N.V. operates by pioneering a next-generation RNA base editing technology called Axiomer, which acts as a highly precise molecular repair kit inside your cells. The company develops Editing Oligonucleotides (EONs) that direct the cell's own natural machinery-Adenosine Deaminase Acting on RNA (ADAR)-to make single-nucleotide changes in messenger RNA (mRNA) to treat the underlying cause of severe rare and common diseases.

Given Company's Product/Service Portfolio

Given Company's Operational Framework

The company's value creation is a two-part strategy: advancing wholly-owned pipeline programs and expanding the platform's reach through strategic partnerships. The core operational process centers on the Axiomer platform, which designs and synthesizes proprietary Editing Oligonucleotides (EONs) to target specific RNA sequences.

This process is highly focused on preclinical and early-stage clinical development. For the nine months ended September 30, 2025, Research and Development (R&D) costs were € 34.8 million, reflecting the heavy investment in moving programs like AX-0810 into human trials. The first human data for AX-0810 is a key near-term milestone for the entire platform. This is a high-risk, high-reward model.

Revenue generation, in the absence of an approved commercial product, comes from collaborations. For example, ProQR earned approximately $2.0 million in milestone payments from its partnership with Eli Lilly and Company during the first nine months of 2025. This collaboration validates the Axiomer technology and provides non-dilutive funding, which is defintely important for a biotech company in the clinical stage.

• Design EONs: Create proprietary RNA sequences to bind target mRNA.
• Induce ADAR: Leverage the cell's natural ADAR enzyme to perform the edit.
• Develop Therapies: Advance edited RNA into functional protein to treat disease.
• Partner for Scale: Use collaborations to apply Axiomer across diverse therapeutic areas.

Given Company's Strategic Advantages

ProQR's primary advantage is its proprietary Axiomer RNA editing technology, which offers a unique approach in the crowded gene therapy space. Unlike gene editing, which permanently alters DNA, Axiomer edits RNA, making the changes reversible and potentially safer, as it avoids permanent genomic alteration. That's a huge selling point for regulators and patients.

The company also benefits from a strong financial position for a firm at this stage. As of September 30, 2025, ProQR held approximately € 106.9 million in cash and cash equivalents, providing a runway into mid-2027. This capital strength allows them to execute their R&D plan without immediate pressure to raise more funds.

• Proprietary Axiomer Platform: Exclusive use of ADAR-mediated RNA editing, a highly specific and differentiated mechanism.
• Leading IP Portfolio: Extensive patent estate built since pioneering ADAR-based EONs in 2014, creating a barrier to entry.
• High-Value Partnerships: Strategic, multi-billion dollar collaboration with Eli Lilly and Company, validating the technology and providing significant potential milestone payments.
• Focus on Liver and CNS: Initial programs target the liver and central nervous system, leveraging proven delivery technologies for these organs.

ProQR Therapeutics N.V. (PRQR) How It Makes Money

ProQR Therapeutics N.V. is a pre-commercial biotechnology company, so it doesn't sell a product yet; its revenue engine is built on collaboration and licensing agreements with larger pharmaceutical partners, essentially monetizing its proprietary Axiomer RNA editing technology platform.

This means the company makes money primarily through upfront payments, research funding, and milestone payments tied to the progress of drug candidates in clinical trials, like the €1.8 million it earned in milestones during the first nine months of 2025.

ProQR Therapeutics N.V.'s Revenue Breakdown

For the nine-month period ending September 30, 2025, ProQR Therapeutics N.V. reported total revenue of €11.218 million. This revenue is almost entirely derived from its strategic partnerships, mainly the expansive collaboration with Eli Lilly and Company.

Here's the quick math on where that revenue comes from, based on the €11.218 million nine-month total:

The overall revenue trend is decreasing, with the nine-month total of €11.218 million in 2025 representing a -23.29% decline compared to the same period in 2024. This drop is expected for a development-stage biotech, as the amortization of large, non-recurring upfront payments from prior years winds down.

Business Economics

The core economic model here is a classic biotech 'platform play.' You're not paying for a pill; you're paying for access to a foundational technology-the Axiomer RNA editing platform-that can generate many potential drug candidates.

• Licensing Structure: The collaboration with Eli Lilly and Company, for example, is a multi-target deal that provides ProQR Therapeutics N.V. with non-dilutive capital. This partnership has a potential total value of up to approximately $3.75 billion in research, development, and commercialization milestones, plus tiered royalties up to a mid-single-digit percentage on future product sales.
• Pricing Strategy (Milestones): The revenue is highly front-loaded and milestone-dependent. The €1.8 million in 2025 came from achieving specific, pre-defined developmental milestones. Future significant payments include a potential $50 million opt-in payment from Eli Lilly and Company if they choose to expand the partnership to additional targets.
• Cost Structure: The company is an R&D machine right now. Research and development (R&D) costs for the nine months ended September 30, 2025, were €34.8 million. This R&D intensity is the primary cost of doing business, as it fuels the pipeline that unlocks those future, high-value milestone payments.

The value of the business today is essentially a function of its intellectual property (IP) and the probability of its lead candidates, like AX-0810, succeeding in clinical trials. That's the real defintely long-term value driver.

ProQR Therapeutics N.V.'s Financial Performance

As of November 2025, the financial performance shows a company heavily investing in its future, which is typical for a clinical-stage biotech.

• Net Loss: For the first nine months of 2025, the company reported a net loss of €33.3 million. This is a necessary burn rate to advance the pipeline from preclinical to clinical stages.
• R&D Investment: R&D spending is up significantly, at €34.8 million for the nine-month period, compared to €25.7 million for the same period in 2024. This increase reflects the cost of initiating the Phase 1 trial for their lead program, AX-0810, which is a critical step.
• Cash Position and Runway: The company is well-capitalized. As of September 30, 2025, ProQR Therapeutics N.V. held cash and cash equivalents of approximately €106.9 million. This strong cash position provides a financial runway that extends into mid-2027. This is the most crucial metric for a biotech: a long cash runway means less immediate risk of needing to raise dilutive capital.
