Item 7.01Regulation FD Disclosure.

 

On June 20, 2023, uniQure N.V. (the “Company”) issued a press release announcing achievement of a $100 million milestone associated with the first commercial sale of HEMGENIX® (etranacogene dezaparvovec) in the United States by its partner, global biotechnology leader CSL Behring. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and incorporated herein by reference.

 

On June 21, 2023, the Company issued a press release announcing updates on its ongoing U.S. Phase I/II clinical trial of AMT-130 gene therapy for the treatment of Huntington’s disease, as described in more detail in Item 8.01 below. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.2 and incorporated herein by reference.

 

The information provided in this Item 7.01, including the accompanying Exhibits 99.1 and 99.2, shall be deemed “furnished” and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of such section, nor shall it be incorporated by reference in any filing made by the Company pursuant to the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, regardless of the general incorporation language of such filing, except to the extent that such filing incorporates by reference any or all of such information by express reference.

 

Item 8.01Other Events.

 

On June 21, 2023, the Company announced promising interim data relating to its ongoing U.S. Phase I/II clinical trial of AMT-130, a one-time administered investigational gene therapy for Huntington’s disease. The interim data includes up to 24 months of follow-up data from the 26 patients enrolled in the ongoing U.S. clinical trial. The trial includes a 10-patient low-dose cohort (six treated patients and four control patients) and a 16-patient high-dose cohort (10 treated patients and six control patients). Patients were randomized to treatment with AMT-130 or an imitation (sham) surgery. The study consists of a blinded 12-month core study period followed by unblinded long-term follow-up of five years for treated patients. To date, four of the six control patients in the high-dose cohort have been crossed over to treatment. Efficacy and biomarker data from the crossover patients were not included in the interim data update.

 

Safety and Tolerability

 

AMT-130 was generally well-tolerated with a manageable safety profile in patients treated with the lower dose of 6x1012 vector genomes and the higher dose of 6x1013 vector genomes. The most common adverse events in the treatment groups were related to the surgical procedure. No treatment emergent adverse events led to discontinuation of patient follow-up.

 

As previously reported, there were two serious adverse events (SAE) unrelated to AMT-130 (post-operative delirium and major depression) in the low-dose cohort, one SAE in the high-dose cohort (back pain), and one SAE (deep vein thrombosis) in the control group. In addition, there were two suspected unexpected SAEs (severe headache, central nervous system inflammation) in the high-dose cohort. All the events have resolved.

 

All four crossover patients (three high dose, one low dose) received a short course of immunosuppression therapy concurrent with the administration of AMT-130. Following a review of the interim data analysis, the Data Safety Monitoring Board for the U.S. Phase I/II clinical trial concluded there are no safety concerns with either dose and recommended continuing clinical development of AMT-130.

 

Exploratory Efficacy Data

 

Clinical and functional measurements for treated patients in each dose cohort were compared to baseline measurements, control patients (up to 12 months) and a natural history cohort. The natural history cohort was developed by the Company in collaboration with the Cure Huntington’s Disease Initiative using the TRACK-HD natural history study of patients with early Huntington’s disease. The natural history cohort includes 31 patients that met the Company’s clinical trial inclusion-criteria of CAG length, age, Total Functional Capacity, Diagnostic Classification Level and minimum striatal volumes.

Early clinical data demonstrate trends consistent with a potential clinical benefit of AMT-130 at both doses of AMT-130.

 

Compared to baseline measurements, clinical function was generally preserved at 24 months for patients in the low-dose cohort and at 12-months for patients in the high-dose cohort.

 

Compared to the natural history, patients in both dose cohorts demonstrated benefits in each of Total Motor Score, Total Functional Capacity and the composite Unified Huntington’s Disease Rating Scale.

 

oTotal Motor Score (TMS): Low-dose patients demonstrated a mean improvement in TMS of 1.8 points at 24 months compared to the natural history and high-dose patients demonstrated a mean improvement of 2.7 points at 12 months.

 

oTotal Functional Capacity (TFC): Low-dose patients demonstrated a mean 0.8 point improvement in TFC at 24 months compared to the natural history and high-dose patients demonstrated a mean 0.5 point improvement at 12 months.

 

oComposite Unified Huntington’s Disease Rating Scale (cUHDRS): Low-dose patients demonstrated a mean 0.9 point improvement in cUHDRS at 24 months compared to the natural history and high-dose patients demonstrated a mean 1.0 point improvement at 12 months.

 

Patients in the control group experienced a worsening of TMS at 12 months compared to baseline measurements and the natural history. TFC and cUHDRS was preserved in control patients at 12 months.

 

 

Biomarkers

 

Neurofilament light chain (NfL)

 

As expected and as previously reported, patients treated with AMT-130 experienced a transient increase in cerebrospinal fluid (CSF) NfL related to the procedure that peaked at approximately one month after administration. These transient increases were not dose-dependent and all patients experienced subsequent declines in CSF NfL.

Mean CSF NfL for the low-dose cohort was 12.9% below baseline measurements compared to a predicted 22.9% increase in the natural history, with four of the five low-dose patients having CSF NfL levels below baseline measurements.

 

CSF NfL levels in the high-dose cohort were more variable through 12 months, with a mean increase of 51.5% compared to baseline. Four of the eight high-dose patients with at least 12 months of follow up had NfL levels below baseline measurements. Two high-dose patients with 18 months of follow-up demonstrated a continued decline in CSF NfL to 27.4% above baseline.

 

In the control group, mean CSF NfL was relatively stable and was 6.83% below baseline measurements at 12-months.

 

 

Mutant Huntingtin protein (mHTT)

 

CSF mHTT for the low-dose cohort remained below baseline measurements with a mean reduction of 8.1% at 24 months. CSF mHTT for the high-dose cohort was significantly more variable with a mean increase of 39.7% above baseline at 12 months compared to a 4.7% increase in the control group. Three of nine evaluable patients in the high-dose cohort had CSF mHTT reduction below baseline measurements at their last measurement.

 

Total Brain Volume

 

The mean total brain volume for the control, low-dose and high-dose cohorts declined 0.74%, 1.02% and 1.23%, respectively at 12 months and were not significantly different from each other or from the natural history.
