Huntington’s disease research news. In plain language. Written by scientists. For the global HD community.
Ionis Pharmaceuticals launched the first ever trial of a huntingtin-lowering drug – sometimes called a 'gene silencing drug' – in late 2015. In a significant update, the company has announced two important milestones: the trial is now fully recruited, and an 'open-label extension' will be activated for the volunteers in the current trial. While nothing is guaranteed, this bodes well for the future of this important program.
What if a blood test could provide information about the status and course of HD? This is the premise of seeking HD biomarkers; they may someday help guide treatment decisions and predict how symptoms will change. A team of researchers spanning multiple countries recently analyzed blood, brain images, and clinical exams from the TRACK-HD study. They found that blood levels of a protein called neurofilament light chain corresponded with the severity of HD, making it a potential biomarker.
If media reports of a "wonder-drug" that could "stop all neurodegenerative brain diseases, including dementia” seem too good to be true, that's because they are. The truth behind the headlines is that researchers tested thousands of already-licensed drugs in worms, and a couple that went on to show beneficial effects in mouse models of two rare forms of dementia. While it gives researchers two new leads, this research doesn't prove anything about these drugs in patients with neurodegenerative diseases, and has virtually nothing to do with Huntington's disease at all.
The final day of the 2017 Huntington's Disease Therapeutics conference brought updates on research to better understand how HD affects brains, and breakthroughs in using brain cells to understand and treat HD.
Day two of the conference looks at some of the most promising approaches to fighting Huntington's disease.
Hi everyone! It's the annual Huntington's Disease Therapeutics Conference in Malta. Around 350 scientists from round the world all working on HD are gathered here to discuss the latest research developments. We're reporting live via twitter and aggregating our updates into daily articles.
Exciting new studies provide evidence that a particular kind of cellular trafficking goes awry in Huntington's Disease. Specifically, researchers have learned that traffic in and out of the cells control center - the nucleus - breaks down in HD. These findings open up new avenues for HD research.
Significant news for the Huntington's disease community this week, as the USA's drug regulator, the FDA, has formally approved Austedo, also known as deutetrabenazine, for prescribing in HD. This modified form of tetrabenazine helps control chorea, the jerky movements often found in HD patients, but is taken twice rather than three times a day.
Beyond affecting movement, mood, and thinking, HD involves a complex set of changes to the body that can be difficult to predict in different individuals. Recently, researchers were able to identify consistent early changes in metabolism by studying a group of HD sheep. This large animal model is helping scientists to track altered substances in the blood that could predict HD progression and response to treatment.
Cannabis, or medical marijuana, has been touted as a treatment for lots of conditions, and Huntington’s disease is no exception. Whenever it hits the news there’s a lot of interest, and recently cannabis found the spotlight again with videos claiming it can reverse the nerve cell damage in Huntington’s disease. These are extraordinary assertions that deserve to be explored.
