uniQure Announces Orphan Drug Designation Granted to AMT-191
for the Treatment of Fabry Disease
LEXINGTON, Mass. and AMSTERDAM, Sept. 23, 2024
(GLOBE NEWSWIRE) -- uniQure N.V. (NASDAQ: QURE), a leading gene
therapy company advancing transformative therapies for patients
with severe medical needs, today announced that the U.S. Food and
Drug Administration (FDA) has granted Orphan Drug Designation to
AMT-191, uniQure’s investigational gene therapy for the treatment
of Fabry disease, a rare, inherited genetic disease. In August
2024, uniQure announced the dosing of the first patient in its
U.S., multi-center, open-label Phase I/IIa trial of AMT-191.
“This important designation highlights the need
for new gene therapies like AMT-191 for patients with Fabry disease
with the potential of delivering meaningful benefit given the
suboptimal effectiveness of current chronic treatments,” stated
Walid Abi-Saab, M.D., chief medical officer of uniQure. “This
designation supports our Phase I/IIa clinical trial and we look
forward to rapidly generating clinical proof-of-concept data and
providing initial data in 2025.”
In patients with Fabry disease, a pathogenic
variant in the galactosidase alpha (GLA) gene leads to
α-galactosidase A (aGAL-A) enzyme deficiency, which in turn results
in a progressive accumulation of lipids in multiple cell types,
including kidney and heart cells, eventually resulting in a
multi-system disorder. AMT-191 is a one-time intravenously
administered investigational AAV5-based gene therapy that uses a
proprietary, highly potent promoter to deliver a GLA transgene
designed to target the liver to produce GLA protein.
The Phase I/IIa clinical trial of AMT-191 will
be conducted in the United States. The multicenter, open-label
trial consists of two cohorts with up to six adult male patients
each: a low-dose cohort of 6x1013 gc/kg and a high-dose
cohort of 3x1014 gc/kg delivered through a one-time
intravenous infusion. Patients will continue to receive their
regular enzyme replacement therapy until the criteria for
withdrawal is met and will be followed for a period of 24 months.
The trial will explore the safety, tolerability, and early signs of
efficacy by measuring the expression of lysosomal enzyme aGLA-A.
Additional details are available on www.clinicaltrials.gov
(NCT06270316).
The FDA’s Orphan Drug Designation provides a
special status for investigational drugs being developed for rare
diseases considered to affect only up to 200,000 people in the
United States. Orphan drug status provides certain incentives,
including tax credits, grants and waiver of certain administrative
fees for clinical trials as well as seven years of market
exclusivity in the United States following drug approval.
About Fabry Disease
Fabry disease is an Xlinked- genetic disorder
resulting from a deficiency of GLA. Based on a 2020 study
published in the Journal of Therapeutics and Clinical Risk
Management, the prevalence is estimated to be between one in 40,000
and one in 117,000 individuals. The current standard of care for
Fabry disease is bi-weekly infusions of enzyme replacement therapy,
a treatment with limited effectiveness in many patients due to
poor cross-correction, with inefficient clearance of substrates in
the target organs, in particular the kidney and the heart.
About uniQure
uniQure is delivering on the promise of gene
therapy – single treatments with potentially curative results. The
approvals of uniQure’s gene therapy for hemophilia B – an historic
achievement based on more than a decade of research and clinical
development – represent a major milestone in the field of genomic
medicine and ushers in a new treatment approach for patients living
with hemophilia. uniQure is now advancing a pipeline of proprietary
gene therapies for the treatment of patients with Huntington's
disease, refractory temporal lobe epilepsy, ALS, Fabry disease, and
other severe diseases. www.uniQure.com

available to management only as of the date of this press release.
Examples of these forward-looking statements include, but are not
limited to, statements regarding the availability of initial
clinical and proof-of-concept data in the Company’s open-label U.S.
Phase I/IIa trial for Fabry disease; the Company’s plans to
announce initial clinical data in 2025; and the AMT-191 trial
design and the differentiated profile relative to other Fabry
programs currently in clinical development. The Company’s actual
results could differ materially from those anticipated in these
forward-looking statements for many reasons. These risks and
uncertainties include, without limitation, risks associated with
the timing and advancement of the Company’s clinical programs; the
Company’s interactions with regulatory authorities, which may
affect the initiation, timing and progress of clinical trials and

continue to build and maintain Company infrastructure and personnel
needed to achieve its goals following planned workforce reductions;
the Company’s effectiveness in managing current and future clinical
trials and regulatory processes; the continued development and
acceptance of gene therapies; the Company’s ability to demonstrate
the therapeutic benefits of its gene therapy candidates in clinical
trials; the Company’s ability to obtain, maintain and protect
intellectual property; and the Company’s ability to fund its
operations and to raise additional capital as needed. These risks
and uncertainties are more fully described under the heading "Risk
Factors" in the Company’s periodic filings with the U.S. Securities
