uniQure Announces Dosing of First Patient in Phase I/II Clinical Trial
of AMT-162 for the Treatment SOD1-ALS
Lexington, MA and Amsterdam, the Netherlands, October 15, 2024 — uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today announced that the first patient has been dosed in the Phase I/II clinical trial of AMT-162 for the treatment of amyotrophic lateral sclerosis (ALS) caused by mutations in superoxide dismutase 1 (SOD1), a rare, inherited and progressive motor neuron disease. EPISOD1 is a Phase I/II multi-center, open-label trial being conducted in the United States with three dose-escalating cohorts assessing the safety, tolerability and exploratory signs of efficacy of AMT-162 in individuals with SOD1-ALS.
“We are pleased to announce the first patient dosing of AMT-162, our investigational gene therapy for the treatment of SOD1-ALS, a debilitating, degenerative and fatal disease,” stated Walid Abi-Saab, M.D., chief medical officer of uniQure. “The start of this trial marks the advancement of our third gene therapy program into the clinic with this trial design, continuing our goal of rapidly generating proof-of-concept data using well-established biomarkers in order to bring treatments to patients as quickly as possible. We believe our novel AAV-based gene therapy candidate can deliver on the convenience of one-time dosing with the potential for a differentiated efficacy profile that is needed for such a devasting disease.”
AMT-162 is an investigational AAVrh10-based gene therapy that expresses a miRNA designed to knock down the expression of the mutated SOD1 protein. Patients with SOD1-ALS express a misfolded SOD1 protein. This misfolded protein is toxic to motor neurons causing degeneration which, over time leads to muscle weakness, loss of function and eventually death. AMT-162 may offer a novel one-time, intrathecally administered approach to slowing or halting the progression of SOD1-ALS. AMT-162 has been granted both Orphan Drug status and Fast Track designation by the U.S. Food and Drug Administration.
The EPISOD1 Phase I/II clinical trial of AMT-162 will be conducted in the United States. The multicenter, open-label trial consists of three cohorts with up to four patients each receiving a short course of immunosuppression prior to and after an intrathecal infusion of AMT-162. The trial will explore the safety and tolerability of AMT-162 and will assess exploratory signs of efficacy by measuring neurofilament light chain, a biomarker of neuronal damage, and SOD1 protein. There are currently four active sites in the U.S. with plans to activate seven additional sites by the first quarter of 2025. Additional details are available on www.clinicaltrials.gov (NCT06100276).
About Amyotrophic Lateral Sclerosis (ALS) caused by mutations in Superoxide Dismutase 1 (SOD1)
SOD1-ALS is a rare, progressive and fatal neurodegenerative disease that results in the loss of motor neurons in the brain and spinal cord. As ALS progresses, individuals experience muscle weakness and atrophy causing them to lose the ability to move their arms and legs, speak, swallow and eventually breathe, causing respiratory failure. Based on a 2021 study in Neuroepidemiology, there are an estimated ~170,000 individuals with ALS globally with SOD1 mutations representing 2% within that population. According to the National Institute of Neurological Disorders and Stroke, the average life expectancy for those diagnosed with ALS is three to five years from onset of symptoms.
