uniQure reported clinical updates for AMT-130 in an 8-K and furnished a press release (Exhibit 99.1) and an investor webcast. The company said FDA discussions allow cohorts 1 and 2 from the Phase I/II studies to be compared to a propensity score-matched external control from the Enroll-HD natural history dataset under a prespecified statistical analysis plan, which may serve as the primary basis for a BLA submission. The company added two protocols to pool data across the U.S. and EU studies and to prespecify the pivotal comparison versus the Enroll-HD external control. Reported outcomes in the release include a statistically significant 75% slowing of disease progression on a composite UHDRS measure, a 60% slowing on Total Functional Capacity, favorable trends in motor and cognitive secondary endpoints including Symbol Digit Modalities Test, and a mean reduction in cerebrospinal fluid neurofilament light protein. The release announced an investor call and a webcast available for replay for 90 days.

Insights

TL;DR: FDA agreement to use a propensity-matched Enroll-HD external control and prespecified pooling increases potential regulatory credibility for AMT-130.

The FDA concurrence to compare Phase I/II cohorts to a propensity score-matched external control from Enroll-HD, together with formalized statistical plans and pooled U.S./EU protocols, strengthens the regulatory pathway by defining a prospective analysis framework. Reported effect sizes (a 75% slowing on the composite cUHDRS and 60% on TFC) are material if supported by full datasets and validated matching. Favorable secondary endpoint trends and a reduction in CSF neurofilament light protein provide supportive biological and clinical signals. Material next steps include full data disclosure, independent validation of the matching methodology, and confirmation that the statistical plan meets FDA expectations for a BLA.

TL;DR: Pre-agreed external control use and prespecified pivotal comparisons reduce regulatory uncertainty but depend on robust methodology.

Agreeing with FDA on using a propensity-matched external control can be an efficient path when randomized controls are limited, but acceptability hinges on transparent prespecified methods, covariate balance, and sensitivity analyses. The supplemental protocols and prespecified pivotal comparison are positive procedural steps; however, regulators will review the matching approach, data quality of Enroll-HD, and pooling justification across regions. The reported clinical effect sizes are promising as described, but material regulatory decisions will require complete, auditable datasets and statistical validation.

Item 7.01 Regulation FD Disclosure.

On September 24, 2025, uniQure N.V. (the “Company”) issued a press release announcing updates on its ongoing clinical trials of AMT-130, as described in more detail in Item 8.01 below.

Item 8.01 Other Events.

On September 24, 2025, the Company announced positive topline data from the pivotal Phase I/II study of AMT-130 for the treatment of Huntington’s disease. The topline data include follow-up data from patients enrolled in the Company’s two ongoing multi-center, dose-escalating Phase I/II clinical trials in the U.S. and Europe. Based on interactions with the U.S. Food and Drug Administration (“FDA”), it was agreed that data from cohorts 1 and 2 in the Phase I/II studies could be compared to a propensity score-matched external control derived from the Enroll-HD natural history data set, under a prespecified statistical analysis plan, which may serve as the primary basis for a Biologic License Application (“BLA”) submission. Based on these interactions, the ongoing Phase I/II AMT-130 clinical trials are supplemented by two additional protocols, each with a statistical plan that was discussed with and submitted to the FDA. The new protocols, among other things, provide for the pooling of data across the ongoing U.S. and EU studies, and also prespecified the pivotal comparison of AMT-130 clinical end points compared to a propensity score-matched external control from the Enroll-HD natural history data set.

In the U.S. study, a total of 26 patients with early manifest Huntington’s disease were randomized to treatment (n=6 low dose; n=10 high dose) or an imitation (sham) procedure (n=10). Treated patients received a single administration of AMT-130 through MRI-guided, convection-enhanced stereotactic neurosurgical delivery directly into the striatum (caudate and putamen). The study consists of a blinded 12-month core study period followed by unblinded long-term follow-up of treated patients for five years. An additional four control patients crossed over to treatment. The European open-label Phase 1b/2 study of AMT-130 enrolled 13 patients with early manifest Huntington’s disease (n=6 low dose; n=7 high dose). A third cohort enrolled an additional 12 patients across sites in the U.S. and EU. This cohort was randomized to explore both doses of AMT-130 in combination with immunosuppression, using the current, established stereotactic administration procedure. A fourth U.S. based cohort, evaluating high-dose AMT-130 in up to 6 patients with lower striatal volumes compared to those of patients enrolled in previous cohorts, is currently enrolling.

In accordance with the prospectively defined statistical analysis plan aligned with, and submitted to, the FDA, the Company analyzed clinical outcomes for 29 patients treated with AMT-130 (n=17 high dose; n=12 low dose) of which 12 patients per dose group had attained 36 months of follow up and were evaluated at that time point. Outcomes for each dose group were compared to a propensity score-matched external control drawn from the Enroll-HD natural history data set respectively (n=940 for high dose; n=626 for low dose).

Topline 36-month efficacy results for patients receiving high-dose AMT-130 are as follows (data cutoff as of June 30, 2025):

A statistically significant 75% slowing of disease progression as measured by composite Unified Huntington’s Disease Rating Scale (“cUHDRS”) (p=0.003), which met the primary endpoint of the study. Treated patients had a mean change in cUHDRS from baseline of -0.38 compared to a change of -1.52 for patients in the propensity score-matched external control.

A statistically significant 60% slowing of disease progression as measured by Total Functional Capacity (“TFC”) (p=0.033), which met a key secondary endpoint of the study. Treated patients had a mean change in TFC from baseline of -0.36 compared to a change of -0.88 for patients in the propensity score-matched external control.

Favorable trends in other secondary endpoint measures of motor and cognitive function (which, with TFC, collectively constitute the composite measurement referred to as cUHDRS), including Symbol Digit Modalities Test (“SDMT”), Stroop Word Reading Test (“SWRT”) and Total Motor Score (“TMS”).

oAn 88% slowing of disease progression as measured by SDMT (p=0.057), with a mean change in SDMT from baseline of -0.44 compared to a change of -3.73 for patients in the propensity score-matched external control.

oA 113% slowing of disease progression as measured by SWRT (nominal p=0.002), with a mean change in SWRT from baseline of 0.88 compared to a change of -6.98 for patients in the propensity score-matched external control.

oA 59% slowing of disease progression as measured by TMS (nominal p=0.174), with a mean change in TMS from baseline of 2.01 compared to a change of 4.88 for patients in the propensity score-matched external control.

A mean reduction from baseline in cerebrospinal neurofilament light protein (“CSF NfL”) of -8.2%. CSF NfL is a well-characterized, supportive biomarker of neurodegeneration. Elevation in CSF NfL has been shown to be strongly associated with greater clinical severity of Huntington’s disease.

The Company believes that the consistently favorable results in functional, motor and cognitive endpoints at 36 months observed in the high dose group, compared to the variable trends observed in the low dose group, reflect a dose-dependent response to AMT-130.

Various other supportive analyses of the results from the AMT-130 high dose treatment group, including those using a propensity score-weighted external control and comparisons to the TRACK-HD and PREDICT-HD datasets, were consistent with the primary analysis.

AMT-130 was generally well-tolerated, with a manageable safety profile at both doses. As of the data cutoff date, no new drug-related serious adverse events have been observed since December 2022. The most common adverse events in the treatment groups were related to the administration procedure, which all resolved.

The Company plans to discuss the AMT-130 data with the FDA at a pre-BLA meeting expected later this year, with the intention of submitting a BLA in the first quarter of 2026.

All statements other than statements of historical fact are forward-looking statements, which are often indicated by terms such as "anticipate," "believe," "could," “establish,” "estimate," "expect," "goal," "intend," "look forward to", "may," "plan," "potential," "predict," "project," “seek,” "should," "will," "would" and similar expressions and the negatives of those terms. Forward-looking statements are based on management's beliefs and assumptions and on information available to management only as of the date of this report. Examples of these forward-looking statements include, but are not limited to, statements concerning: the Company’s plans to explore AMT-130 in a fourth cohort of up to 6 patients with lower striatal volumes compared to those patients enrolled in previous cohorts; the Company’s plans to have a pre-BLA meeting with the FDA later this year, and the Company’s plans to submit a BLA for AMT-130 in the first quarter of 2026. The Company’s actual results could differ materially from those anticipated in these forward-looking statements for many reasons. These risks and uncertainties include, among others: risks related to the Company’s Phase I/ll clinical trials of AMT-130, including the risk that such trials will be unable to demonstrate data sufficient to support further clinical development or regulatory approval; the risk that topline data may not be predictive of later data readouts; risks related to the Company’s interactions with regulatory authorities, which may affect the initiation, timing and progress of clinical trials and pathways to regulatory

approval; whether the measurements that the Company is evaluating continue to be viewed as robust and sensitive measurements of disease progression; whether Regenerative Medicine Advanced Therapy designation, Breakthrough Therapy designation, or any accelerated pathway, if granted, will lead to regulatory approval; the Company’s ability to conduct and fund a Phase III or confirmatory study for AMT-130 if needed; the Company’s ability to continue to build and maintain the infrastructure and personnel needed to achieve its goals; the Company’s effectiveness in managing current and future clinical trials and regulatory processes; the Company’s ability to demonstrate the therapeutic benefits of its gene therapy candidates in clinical trials; the continued development and acceptance of gene therapies; the Company’s ability to obtain, maintain and protect its intellectual property; and the Company’s ability to fund its operations and to raise additional capital as needed and on acceptable terms. These risks and uncertainties are more fully described under the heading "Risk Factors" in the Company’s periodic filings with the U.S. Securities & Exchange Commission (“SEC”), including its Annual Report on Form 10-K filed with the SEC on February 27, 2025, its Quarterly Reports on Form 10-Q filed with the SEC on May 9, 2025 and July 29, 2025, and in other filings that the Company makes with the SEC from time to time. Given these risks, uncertainties and other factors, you should not place undue reliance on these forward-looking statements and, except as required by law, the Company assumes no obligation to update these forward-looking statements, even if new information becomes available in the future.
