Lexington, MA; Amsterdam, the Netherlands;

and Paris, France, June 22, 2021 - uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative

therapies for patients with severe medical needs, today announced it has entered into a definitive agreement to acquire Corlieve Therapeutics

and its lead program, which will be known as AMT-260, to treat temporal lobe epilepsy, the most common form of focal epilepsy.

Corlieve's lead gene therapy program employs

miRNA silencing technology to target suppression of aberrantly expressed kainate receptors in the hippocampus of patients with temporal

lobe epilepsy (TLE). TLE affects approximately 1.3 million people in the U.S. and Europe alone, of which approximately 800,000 patients

are unable to adequately control acute seizures with currently approved anti-epileptic therapies. Patients with refractory TLE experience

increased morbidity, excess mortality, and poor quality of life.

AMT-260 was originally developed by Corlieve in

collaboration with Christophe Mulle, Ph.D., CNRS Research Director, at the Interdisciplinary Institute of Neurosciences, CNRS, University

of Bordeaux, Valerie Crepel, Ph.D., Inserm Research Director at the Institut de Neurobiologie de la M diterran e, INSERM,

Aix-Marseille University, and REGENXBIO Inc. Drs. Mulle and Crepel will continue their collaborations with uniQure.

"The acquisition of Corlieve provides an

extraordinary opportunity to transform the lives of hundreds of thousands of patients around the world suffering from epilepsy and aligns

with our vision of pursuing unmet medical needs for disorders that impact large populations and can be addressed with gene therapies directed

to the CNS and liver," stated Matt Kapusta, Chief Executive Officer of uniQure. "The groundbreaking work of the Corlieve team,

in collaboration with Drs. Mulle and Crepel and others, has led to compelling preclinical results in temporal lobe epilepsy that

we believe can strategically leverage uniQure's leading position in developing and delivering gene therapies that employ miRNA silencing

technology. We look forward to welcoming the Corlieve team into the uniQure family as we join forces to advance this important and potentially

transformative therapy into clinical studies."

"I am very proud of what Corlieve has

achieved in such a short amount of time. With the dedication and focus of our team and our collaboration partners, we have taken a

promising therapeutic approach discovered by our scientific founders and created a potential transformative therapeutic opportunity

for patients with refractory TLE," said Richard Porter, Ph.D., founder

and Chief Executive Officer of Corlieve. "As leaders in the field for miRNA gene therapy for neurological conditions, uniQure is

the ideal long-term partner for us, and we look forward to working together to advance our program rapidly to the clinic for the benefit

of the patients we serve."

Upon the closing of the transaction, Dr. Porter

will assume the role at uniQure of General Manager of the Corlieve subsidiary.

"As a founding investor, we are delighted

to see that the translational work conducted by Corlieve is recognized by uniQure, further reinforcing our commitment to company creation

based on partnering with the industry," said Vanessa Malier, Managing Partner at Kurma Partners and Chairman of Corlieve.

Under the terms of the agreement, uniQure will

pay 46.3 million in an upfront payment of cash to acquire Corlieve.

Corlieve shareholders are eligible to receive

the following additional payments of which up to 25% will be payable in uniQure ordinary shares at uniQure's election: up to 43.7

million in development milestones through Phase I/II and 160 million in milestones associated with Phase III development and the

approvals of AMT-260 in the U.S and European Union.

Corlieve has an established license and collaboration

agreement with REGENXBIO that includes an exclusive license to AAV9 for the specific genetic target of AMT-260. Under the license and

collaboration agreement, REGENXBIO received equity in Corlieve and is eligible to receive milestone payments and royalties on net sales

The transaction has been approved by the

Boards of both companies and does not require uniQure shareholder approval. The transaction is subject to customary closing

conditions as well as review by the French Ministry of Economy, Finance and Recovery (Minist re de l'Economie, des

Finances et de la Relance) pursuant to articles L.151-3 and R.151-1 and seq. of the French Code Mon taire et Financier.

Currently, the transaction is anticipated to be completed early in the third quarter of 2021.

SVB Leerink LLC is acting as sole financial advisor

and Morgan Lewis is acting as legal advisor to uniQure. McDermott Will & Emery is acting as legal advisor to Corlieve.
