With the holidays approaching, welcome news arrived on December 19th in a press release from uniQure. The latest data from the HD-GeneTRX studies of AMT-130, an experimental huntingtin-lowering gene therapy, shows that the drug still appears to be safe over the course of a few years. Since the number of participants is very small, we cannot yet draw conclusions about the effectiveness of AMT-130 to treat HD, but there are early, promising signs that AMT-130 holds potential to stabilize some symptoms. This means that the trial can safely continue and will hopefully expand in future.
A refresher on the HD-GeneTRX trials
First, let’s talk about the history of the first gene therapy for HD. Developed by uniQure, AMT-130 involves a harmless virus packaged with genetic material that is designed to lower the amount of huntingtin protein in the brain. We’ve covered a bit more on the science of this in a 2019 article. It was first thoroughly tested in many different animal models of HD before the current human safety studies, known as HD-GeneTRX-1 and HD-GeneTRX-2, began in 2020.
