LEXINGTON, Mass. and AMSTERDAM, March 02, 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 fourth quarter and full year of 2025 and highlighted recent progress across its business.

“In 2025, we presented compelling 36-month clinical data from AMT-130 that we believe meaningfully demonstrate its potential to become a first disease-modifying therapy for people living with Huntington’s disease,” said Matt Kapusta, chief executive officer at uniQure. “While we have not reached alignment with the FDA on an approval pathway, we remain confident in the strength and durability reflected in our dataset. We are committed to engaging with the FDA to define a clear and efficient path to bring this potentially transformative therapy to Huntington’s disease patients in urgent need for treatments.”

“Beyond Huntington’s disease, we have also made meaningful progress across our broader clinical portfolio and look forward to additional data readouts later this year,” continued Mr. Kapusta. “Entering 2026 with a strong balance sheet, we remain financially disciplined and well-positioned to continue advancing our programs strategically and responsibly.”

Recent Company Developments and Updates

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

• In September 2025, the Company announced positive topline data from the pivotal Phase I/II study for AMT-130 for the treatment of Huntington’s disease. Topline 36-month efficacy results for 12 patients receiving high-dose AMT-130 included the following (data cutoff as of June 30, 2025):
  
  • • A statistically significant 75% slowing in disease progression measured by the composite Unified Huntington’s Disease Rating Scale (cUHDRS) was observed which met the primary endpoint compared to a propensity score-matched external control (p=0.003).
    • A key secondary endpoint of Total Functional Capacity (TFC) demonstrated a statistically significant 60% slowing of disease progression compared to a propensity score-matched external control (p=0.033).
  • A mean reduction from baseline in cerebrospinal neurofilament light protein (NfL) of -8.2% was observed at 36 months in the high-dose of AMT-130 of the Phase I/II studies.
  • AMT-130 was generally well-tolerated across both doses, with a manageable safety profile and no new drug-related serious adverse events observed since December 2022. The most common adverse events in the treatment groups were related to the administration procedure.
• In the fourth quarter of 2025, dosing was completed in a fourth cohort of six patients receiving high-dose AMT-130 to evaluate safety and efficacy in patients with lower baseline striatal volumes compared to previous cohorts in the U.S. Phase I/II study.
• On February 23, 2026, the Company presented new analyses at the 21^st Annual Huntington’s Disease Therapeutics Conference in Palm Springs, California showing that propensity score methodology using clinical covariates with TRACK-HD/TRACK-ON and PREDICT-HD datasets effectively substitutes for baseline striatal volume in predicting Huntington’s disease progression. These covariates were the same as those used in the 3-year data analysis to match AMT-130-treated patients to the external comparator cohort derived from Enroll-HD.
• The Company held a pre-BLA meeting with the U.S. Food and Drug Administration (FDA) in October 2025 and a Type A meeting in January 2026 to discuss the regulatory path forward. 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 FDA strongly recommended the Company conduct a prospective, randomized, double-blind, sham surgery-controlled study. The Company intends to continue engaging with the FDA regarding Phase III development considerations and plans to request a Type B meeting in the second quarter of 2026 to further discuss potential study design approaches.

Continued clinical progress in pipeline programs

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

• In May 2025, the Company presented initial safety and exploratory efficacy data from the first treated patient showing a 92% reduction in seizure frequency observed through the first five months of follow up, with no serious safety events.
• In 2025, the Company completed enrollment in the first dose cohort of six patients in the Phase I/IIa study. Enrollment has been initiated in a second dose cohort expected to include an additional six patients.
• The Company expects to provide updated data from the Phase I/IIa study in the second quarter of 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 312.52-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. 
    • Six of 11 dosed patients were withdrawn from enzyme replacement therapy (ERT).
    • Plasma lyso-Gb3 levels were stable post-dose across all cohorts, regardless of ERT status
• Based on data observed to date, AMT-191 showed a manageable safety profile at all dose levels. No SAEs related to AMT-191 were observed at the 4×10¹³ gc/kg and 2×10¹³ gc/kg doses. No additional SAEs were observed at the 6×10¹³ 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)

• Enrollment remains on voluntary pause following the Independent Data Monitoring Committee recommendation after review of preliminary safety and efficacy data in September 2025, which included one serious adverse event of dose-limiting toxicity determined to be related to AMT-162. The Company continues to collect and evaluate data from the five patients treated in the Phase I/II EPISOD1 study. 

Strengthened financial position

• In 2025, the Company received aggregate net proceeds of $404.2 million, after deducting underwriting discounts and commissions and other offering expenses, through the completion of follow-on public offerings in which a total of 11.8 million ordinary shares were issued, and in lieu of ordinary shares to certain investors, pre-funded warrants to purchase 0.5 million of the Company’s ordinary shares.
• In the third quarter of 2025, the Company further announced the refinancing of its existing $50 million debt outstanding to extend the term to October 2030 and reduce its cost of capital. An additional term loan tranche of $100 million could be drawn down at the Company’s option subject to the achievement of a pre-defined regulatory milestone for AMT-130. A third tranche of $25 million is available subject to the lender’s approval.
• As of December 31, 2025, the Company had cash, cash equivalents and current investment securities of $622.5 million. The Company expects that cash, cash equivalents and investment securities will be sufficient to fund operations into the second half of 2029.
