HD Clinical Trials In Canada

The Huntington Society of Canada (HSC) plays a key role in bridging the relationship between researchers and individuals by educating Canadians on the importance of the clinical trial process, how to get involved and why participation is so crucial. The urgency lies in not only educating as many people as possible, including efforts in rural and culturally diverse communities, but also ensuring clinicians have sustainable mechanisms in place to support the process.

HSC is emerging as a leader in linking researchers and clinicians in order to continually prepare for future trials. Drugs being tested now have been specifically designed for Huntington disease (HD). This is a significant step forward. Managing HD will take the collective efforts of researchers, scientists, clinicians, the Huntington Society of Canada and HD families all have to work together. It is our best chance for success.

2015 was an important year for HD clinical trials. Participation in Enroll-HD will facilitate your involvement in clinical trials when they are available in your area. Enroll-HD is a platform that allows health-care professionals, scientists, and families affected by HD to work together towards a better understanding of HD and identify effective treatments. Their objective is to create the world’s largest database for clinical research on HD, eventually including information from as many as 20,000 people in 33 countries.

Clinical Trials Currently In Progress

  • Deep Brain Stimulation (DBS) is a common treatment for Parkinson’s. A small pilot trial involving five individuals with HD has already happened in Europe. A larger multicentre trial to include more individuals with HD is now underway in Europe, with the intended outcome of providing more definitive results.
  • Amaryllis is a multicentre Pfizer trial of a PDE10 Inhibitor drug that may help neurons to communicate more effectively. 
  • Pride-HD (Pridopidine) may help with movement symptoms. A Teva sponsored trial. 
  • Legato-HD aims to calm down the immune system in HD. A Teva sponsored trial. 
  • ISIS-HTTRx is the first huntingtin-lowering potential treatment for HD. The drug will be injected into the spinal fluid to allow it to reach the brain, then tell the cells not to make the harmful huntingtin protein that causes HD. This is a world first for this method, which most HD researchers consider to be the most promising approach to treating HD.
