uniQure N.V. (NASDAQ: QURE), a leading gene therapy company dedicated to developing transformative therapies for severe medical conditions, has recently shared promising interim data from its Phase I/II clinical trials of AMT-130 for Huntington’s disease. This update includes up to 24 months of follow-up data from 29 treated patients enrolled in these ongoing studies in the U.S. and Europe.
Overview of Huntington’s Disease and Current Challenges
Huntington’s disease (HD) is a progressive neurodegenerative disorder caused by a genetic mutation that leads to the degeneration of nerve cells in the brain. Patients with HD experience a gradual decline in motor and cognitive functions, often accompanied by psychiatric disturbances. This disease deteriorates the quality of life and currently has no cure, making it a critical area of focus for medical research and therapeutic development. AMT-130 is an investigational gene therapy designed to modify the expression of the mutant huntingtin protein responsible for HD. Unlike traditional treatments that necessitate continuous usage, AMT-130 aims to deliver long-term benefits through a single administration. The therapy employs an adeno-associated virus (AAV) to deliver a therapeutic transgene directly into the brain, targeting the underlying cause of HD at the genetic level.
The recent interim data update from uniQure’s Phase I/II trials provides a glimmer of hope for patients suffering from Huntington’s disease. Here are the findings:
Dose-Dependent Slowing of Disease Progression:
The trials demonstrated a statistically significant, dose-dependent slowing of disease progression. This outcome was measured using various clinical endpoints, including motor and cognitive function assessments.
Reduction in Neurofilament Light Chain (NfL) Levels:
NfL is a biomarker associated with neurodegeneration. The trials showed a reduction in NfL levels in the cerebrospinal fluid (CSF) of treated patients at the 24-month mark. This reduction indicates a potential slowdown in neuronal damage.
Dr. Walid Abi-Saab, Chief Medical Officer of uniQure, emphasized the importance of these findings, stating, “We believe this is the first clinical trial of any investigational medicine for Huntington’s disease to show evidence of a potential long-term clinical benefit and reduction of a key marker of neurodegeneration.”
Clinical Trial Design and Analysis
uniQure is conducting two multi-center Phase I/II clinical trials of AMT-130, one in the U.S. (n=26) and one in Europe/UK (n=13). A total of 29 patients received either a low dose (n=12) or high dose (n=17) of AMT-130, while 10 control patients underwent imitation surgery. As of March 31, 2024, 24-month follow-up data from 21 treated patients were available for analysis. For the first time, a statistical analysis was conducted comparing the clinical outcomes of the 21 treated patients with an external control group (n=154) developed in collaboration with the Cure Huntington’s Disease Initiative (CHDI). This external control group included patients from the TRACK-HD, TRACK-ON, and PREDICT-HD natural history studies, and was statistically weighted to match the baseline characteristics of the treated cohort.
The promising results have garnered attention and optimism within the medical community. Dr. Victor Sung, a professor of neurology at the University of Alabama at Birmingham and director of the UAB Huntington’s Disease Clinic, remarked on the importance of the findings. “The preservation of motor and cognitive function observed through two years, combined with reduced NfL levels below baseline, defy expectations about the natural progression of Huntington’s disease,” he said. Dr. Sung highlighted the importance of composite Unified Huntington’s Disease Rating Scale (cUHDRS) as a measure of disease progression, which has shown to be robust and sensitive. These long-term data suggest that AMT-130 may offer durable disease-modification, providing much-needed hope for a community in desperate need of therapeutic options.
uniQure plans to continue accumulating longer-term patient outcomes from the Phase I/II studies to support the emerging therapeutic benefit. Additionally, they look forward to discussing the potential for expedited clinical development of AMT-130 during an initial, multi-disciplinary RMAT meeting with the FDA later this year. The interim data from uniQure’s Phase I/II trials of AMT-130 represent an achievement in the search for effective treatments for Huntington’s disease. The dose-dependent slowing of disease progression and reduction in NfL levels provide compelling evidence of the potential therapeutic benefits of this one-time gene therapy.
As uniQure continues to gather long-term data and engage with regulatory authorities, there is renewed hope for patients and families affected by Huntington’s disease. The road ahead includes further validation and rigorous review, but the progress made thus far marks a crucial step forward in addressing this devastating condition.
