Gene Therapy:

Huntington's Disease

uniQure's has demonstrated preclinical proof-of-concept and initiated IND-enabling studies in Huntington's Disease.

Huntington’s Disease (HD)

uniQure is developing a gene therapy for Huntington’s disease, a rare, inherited neurodegenerative disorder that leads to loss of muscle coordination, behavioral abnormalities and cognitive decline, resulting in complete physical and mental deterioration over a 12- to 15-year period of time.  The disease is caused by an autosomal dominant mutation, a cytosine-adenine-guanine (CAG) expansion, in the first exon of the huntingtin gene leading to a non-functional, aggregation-prone mutated protein.

Our product candidate AMT-130 consists of an AAV5 vector carrying an artificial micro-RNA which silences the huntingtin gene. The therapeutic goal is to inhibit the production of the mutant protein.  Using AAV vectors to deliver micro-RNAs directly to the brain represents a highly innovative approach to treating Huntington’s disease.

uniQure achieved preclinical proof-of-concept in early 2016 with the publication of data demonstrating the potential of a one-time administration of AAV5-delivered gene therapy to successfully silence the huntingtin gene (view publication).  In April 2017, uniQure published two additional preclinical studies that support moving forward with clinical trials of this promising gene therapy.  This includes data demonstrating widespread transduction in the central nervous system following direct injection of uniQure's AAV5 vector in a large animal model (view publication).  Data from a second study demonstrated widespread and effective AAV5 vector distribution and extensive silencing of the human mutant huntingtin gene (HTT) in minipigs, among the largest HD animal models available for testing (view poster presentation).  This study is an important step in our Huntington’s disease gene therapy program, demonstrating for the first time in a large animal model that AAV5 can be used safely and effectively to deliver micro-RNAs to silence mutant huntingtin. We are very encouraged by the significant reductions in mutant huntingtin protein, and believe that knock-down of this magnitude has the potential to significantly alter the course of the disease.  

We expect to file an Investigational New Drug (IND) application and to enter clinical development for AMT-130 in 2018.
