LEXINGTON, Mass. and AMSTERDAM, May 05, 2026 (GLOBE NEWSWIRE) -- uniQure N.V. (NASDAQ:QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today reported its financial results for the first quarter of 2026 and highlighted recent progress across its business.

"During the first quarter of 2026, we remained focused on advancing AMT-130 to patients globally as rapidly as possible while executing across our broader pipeline," said Matthew Kapusta, chief executive officer at uniQure. "We believe our data continue to support the potential for AMT-130 to fundamentally change the treatment landscape for Huntington's disease, and we look forward to continued engagement with the FDA. In parallel, following a constructive interaction with the MHRA, we are preparing to submit an MAA in the third quarter and evaluating additional international opportunities."

"We expect to deliver key clinical updates throughout 2026, including data from our AMT-260 program in refractory mesial temporal lobe epilepsy later in the second quarter and four-year AMT-130 data analysis in the third quarter," Mr. Kapusta continued. "With these important milestones ahead, we remain committed to advancing our programs with urgency while maintaining disciplined capital allocation to drive long-term shareholder value."

Recent Company Developments and Updates

Advancing AMT-130 for the treatment of Huntington's disease

• The Company held a Type A meeting with the U.S. Food and Drug Administration (FDA) in January 2026 to discuss the regulatory path forward following an October 2025 pre-Biologics License Application (BLA) meeting. Following receipt of final meeting minutes from the Type A meeting, the Company announced that the FDA stated it cannot agree that data from the Phase I/II studies, compared to an external control, are sufficient to provide the primary evidence of effectiveness required to support a marketing application for AMT-130.
  
  
• The Company has been granted a Type B meeting with the FDA and plans to discuss key elements of a new clinical trial design and to solicit feedback on the proposed statistical analysis plan for the four-year data expected in the third quarter of 2026.
  
  
• Following a constructive pre-submission meeting with the United Kingdom's (UK) Medicines and Healthcare products Regulatory Agency (MHRA), the Company expects to submit a Marketing Authorization Application (MAA) for AMT-130 based on three-year data in the third quarter of 2026.
  
  

Continued clinical progress in pipeline programs

AMT-260 for the treatment of refractory mesial temporal lobe epilepsy (MTLE)

• In 2025, the Company completed enrollment in the first dose cohort of six patients in the Phase I/IIa study. Enrollment is ongoing in a second dose cohort, expected to include an additional six patients. Enrollment of the second cohort is expected to be completed in mid-2026.
  
  
• The Company expects to provide data from the first cohort of six patients in the Phase I/IIa study with up to six months of follow-up at the Epilepsy Foundation Pipeline Conference, June 18 -19, 2026.
  
  

AMT-191 for the treatment of Fabry disease

• In February 2026, the Company presented updated safety and exploratory efficacy data from the Phase I/II study of AMT-191 in Fabry disease (data cutoff as of January 8, 2026):
  
  
  
  
  • Dose-dependent elevations were observed across 11 patients in three dose levels with α-Gal A activity ranging from 0.34- to 82.2-fold above mean normal range¹ at the lowest dose, 1.6- to 312.5-fold at the mid dose, and 27.7- to 223.7-fold at the highest dose. These increases were durable across follow-up periods ranging from four months to more than one year.
    
    
  • Plasma lyso-Gb3 levels were stable post-dose across all cohorts, regardless of enzyme replacement therapy (ERT) status.
    
    
    
    
• As of February 18, 2026, all 11 dosed patients were withdrawn from ERT.
  
  
• AMT-191 continued to show a manageable safety profile at all dose levels. No SAEs related to AMT-191 were observed at the 4x10¹³ gc/kg and 2x10¹³ gc/kg doses. No additional SAEs were observed at the 6x10¹³ gc/kg dose beyond the five previously reported in September 2025 in two patients.
  
  
• Per protocol, additional dosing in the mid- and high-dose cohorts has been paused pending further evaluation of asymptomatic Grade 3 liver enzyme elevations reported in two patients from the mid-dose cohort, which were confirmed as dose-limiting toxicities.
  
  

AMT-162 for the treatment of SOD1 amyotrophic lateral sclerosis (ALS)

• In 2025, the Company voluntarily paused enrollment in the Phase I/II EPISOD1 multi-center, open-label U.S. trial of AMT-162 for the treatment of SOD1-ALS, following an Independent Data Monitoring Committee review of available preliminary safety and efficacy data, including a SAE determined to be a dose-limiting toxicity observed in one patient in the second cohort. Following review of the preliminary efficacy and safety data generated from EPISOD1, the decision was made to discontinue development of AMT-162.   Safety data will continue to be collected from the five patients dosed in EPISOD1, consistent with applicable safety and regulatory requirements.
  
  

Focused execution and strong financial position

• In April 2026, uniQure, CSL Behring and Genezen entered into agreements under which uniQure's remaining HEMGENIX® supply and any minimum purchase commitments will terminate after delivery of contractually specified batches to CSL Behring, which uniQure expects to occur in mid-2026. Concurrently, CSL Behring entered into a direct relationship with Genezen as the supplier of HEMGENIX®. These agreements have no impact on future royalties or milestones to uniQure under the license agreement with CSL Behring.
  
  
• As of March 31, 2026, the Company had cash, cash equivalents and current investment securities of $586.6 million. The Company expects that cash, cash equivalents and investment securities will be sufficient to fund operations into the second half of 2029.
  
  

Financial Highlights

Cash Position: As of March 31, 2026, the Company held $586.6 million in cash, cash equivalents and current investment securities, compared to $622.5 million as of December 31, 2025. The Company expects that cash, cash equivalents and investment securities will be sufficient to fund operations into the second half of 2029.

Revenues: Revenue for the three months ended March 31, 2026 was $3.6 million, compared to $1.6 million in the same period in 2025. The increase of $2.0 million is due to an increase in license revenue, compared to the prior period.

R&D Expenses: Research and development expenses were $29.2 million for the three months ended March 31, 2026, compared to $36.1 million during the same period in 2025. The $6.9 million decrease was driven by a $2.6 million decrease in the fair value of contingent consideration, a $1.2 million decrease in costs related to external program spend, a $1.6 million decrease in employee and contractor-related expenses, including share-based compensation, and a $1.6 million decrease in facilities and other expenses, compared to the prior period.

SG&A Expenses: Selling, general and administrative expenses were $20.1 million for the three months ended March 31, 2026, compared to $10.9 million during the same period in 2025. The $9.2 million increase was primarily related to a $5.5 million increase in employee and contractor-related expenses, including share-based compensation, mainly as a result of employees recruited in 2025 to support commercial planning of AMT-130, a $1.8 million increase in professional fees, a $0.6 million increase in intellectual property fees, and a $1.3 million increase in information technology costs and other expenses, compared to the prior period.

Other Income: Other income was $1.6 million for the three months ended March 31, 2026, compared to $8.3 million during the comparative period in 2025. The $6.7 million decrease was primarily related to a prior period one-time gain of $6.0 million related to the sale of critical reagents and a $0.8 million decrease in research and development grants, compared to the prior period.

Other Expense: Other expense was $1.5 million for the three months ended March 31, 2026, compared to $2.0 million during the same period in 2025. The decrease was primarily due to a $0.3 million decrease in costs associated with the supply of Hemgenix® to CSL Behring and a $0.2 million decrease in sublease expenses in the three months ended March 31, 2026, compared to the prior period.

Other non-Operating Items, net: Other non-operating items, net was an expense of $7.3 million for the three months ended March 31, 2026, compared to an expense of $3.8 million for the same period in 2025. The $3.5 million increase was primarily related to an increase in net foreign currency losses of $9.5 million, offset by a $1.1 million increase in interest income, a $1.1 million decrease in interest expense, and a $3.8 million gain resulting from changes in the fair value of the liability related to pre-funded warrants, compared to the prior period.

Net loss: The net loss for the three months ending March 31, 2026, was $53.5 million, or $0.85 basic and diluted loss per ordinary share, compared to a $43.6 million net loss for the comparative period in 2025, or $0.82 basic and diluted loss per ordinary share.
