This presentation contains forward-looking statements. All statements other than statements of historical
fact are forward-looking statements, which are often indicated by terms such as “anticipate,” “believe,”
“could,” “estimate,” “expect,” “goal,” “intend,” “look forward to,” “may,” “plan,” “potential,” “predict,” “project,”
“should,” "will,” “would” and similar expressions. Forward-looking statements are based on management's
beliefs and assumptions and on information available to management only as of the date of this press
release. These forward-looking statements include, but are not limited to, statements regarding the
development of our gene therapies, the success of our collaborations, and the risk of cessation, delay or
lack of success of any of our ongoing or planned clinical studies and/or development of our product
candidates. Our actual results could differ materially from those anticipated in these forward-looking
statements for many reasons, including, without limitation, risks associated with collaboration arrangements,
our and our collaborators’ clinical development activities, regulatory oversight, product commercialization
and intellectual property claims, as well as the risks, uncertainties and other factors described under the
heading “Risk Factors” in uniQure’s 2016 Annual Report on Form 10-K filed with the Securities and
Exchange Commission on March 15, 2017. Given these risks, uncertainties and other factors, you should
not place undue reliance on these forward-looking statements, and we assume no obligation to update

• Dose-dependent reduction of HTT in HD rodent and tgHD minipig models translates
in therapeutic benefit.
• Widespread vector distribution upon (MRI-guided) CED delivery in NHP and tgHD
minipigs supported selection of striatum as the target brain structure.
• Long-term expression, tolerability and efficacy supports further clinical
development of HTT-lowering gene therapy for HD with AMT-130.

Effective liver-directed gene delivery,
despite the presence of neutralizing
antibodies in non-human primates
Harald Petry, Ph.D.
Chief Scientific Officer
M A Y 1 2 , 2 0 1 7 | 18
Approach:
• NAB impact on AAV5 transduction was tested in 14 NHP
• Sera of those 14 NHP all had pre-existing anti-AAV5 NAB titers ranging from 1:57 to 1:1031
• Those 14 NHP were injected intravenously with increasing doses of AAV5-hFIX:
• 5e11 gc/kg (n=3)
• 5e12 gc/kg (n=5)
• 2.5e13 gc/kg (n=3)
• 9.3e13 gc/kg (n=3)
• Transduction efficiency was assessed by measuring:
• Circulating FIX protein levels in plasma 7 days after vector infusion.
• Vector DNA in the liver 6 months after vector infusion (post mortem).
Impact of neutralizing antibodies (NAB) directed against AAV5 on
efficacy of liver directed gene delivery in non-human primates (NHP)

• Demonstration that successful AAV5-based liver-directed gene delivery can be
achieved in NHP, despite the presence anti-AAV NAB titers up to at least 1:1031.
• Poses question whether patients with pre-existing anti-AAV5 antibodies could benefit
from AAV5-based gene therapy.

Successful repeated hepatic gene delivery
in non-human primates achieved with AAV5
by use of immune adsorption
Valerie Sier-Ferreira, Ph.D.
Head of Immunology
M A Y 1 2 , 2 0 1 7 | 23
Background:
• Presence of circulating neutralizing antibodies (NABs)
against AAV vector capsids impair transduction of the
target cells and therapeutic efficacy.
Goal:
• To overcome anti-AAV pre-existing antibodies due to
exposure to wild type AAV
o To increase the number of patients eligible for the therapy
• To overcome anti-AAV antibodies raised after exposure to
AAV therapy
o To facilitate re-administration of AAV gene therapy
Approach:
• Immuno-adsorption procedure
M A Y 1 2 , 2 0 1 7 | 24
• Experimental set-up proof of concept in NHPs
• Mean Reduction levels NABs by immuno-adsorption: 11 times
M A Y 1 2 , 2 0 1 7 | 25
• SEAP and hFIX transgenes expression
o Proteins levels
o mRNAs levels
M A Y 1 2 , 2 0 1 7 | 26
• Data demonstrate that the use of an immune adsorption procedure enables
successful re-administration of an AAV5-based gene transfer in NHPs.

Fluorescent in situ hybridization (FISH):A powerful method to determine DNA/RNA
distribution following AAV-based gene delivery
M A Y 1 2 , 2 0 1 7 | 28
“haat-GFP” vector DNA/RNA is visualized in green (FISH), Albumin RNA in purple (FISH), GS protein in blue (IHC)
Why FISH and IHC?
• To determine distribution
• To determine the cell specificity
• To quantify on the level of “a cell”
Following liver targeted AAV gene delivery
M A Y 1 2 , 2 0 1 7 | 29

Image analysis
(confocal microscopy,
HALO program)
M A Y 1 2 , 2 0 1 7 | 30
M A Y 1 2 , 2 0 1 7 | 31
• The combination of FISH and IHC permit to assess the physiological transduction
profile of AAV in the liver which is a valuable tool to further optimize AAV-targeting.
• To develop AAV-based gene therapies with increased efficiency and selectivity.
