Huntington’s disease research news. In plain language. Written by scientists. For the global HD community.
New hints are emerging about the normal role of the gene that causes Huntington's disease. A recent report uses cutting edge techniques to study this question in cells growing in the lab. We'll help separate the fascinating new science from some scary-sounding headlines.
A recent mouse study of a drug known as CTEP suggests the drug is surprisingly helpful for HD-like symptoms in mice. This is a welcome surprise, because it suggests a well-understood brain process might be a useful drug target for future HD research.
The research news, announced on 11 December 2017, that a research team from the Huntington's Disease Centre at University College London have made significant step towards a possible treatment for Huntington's disease, raised many questions for the Huntington's disease community. Dr Ed Wild answered some of these questions on behalf of the UK HD Association, helping to give some context to what this news means for people affected by Huntington's now and in the future.
In an announcement likely to stand as one of the biggest breakthroughs in Huntington's disease since the discovery of the HD gene in 1993, Ionis and Roche today announced that the first human trial of a huntingtin-lowering drug, IONIS-HTTRx, demonstrates that it reduces mutant huntingtin in the nervous system, and is safe and well-tolerated.
Genome editing is a much-discussed frontier in medical science at the moment, with ‘DNA surgery’ having the potential to treat or cure genetic diseases like Huntington’s. Here we look at what this technology can currently do and discuss the challenges that still lie in the way. We’ll also discuss how a team of Swiss scientists have recently developed a way to switch off the genome-editing machinery after it’s done its job.
A new analysis of clinical data from the TRACK-HD and COHORT studies proposes a way to design of clinical trials designed to delay the onset of HD, rather than treating symptoms after they occur.
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.
Some techniques aimed at lowering mutant huntingtin can also affect the normal form of the protein. With clinical trials underway, it’s all the more important to understand the role of normal huntingtin in the adult brain. Researchers recently inactivated the huntingtin gene in healthy adult mice of different ages. They found that this could cause neurological and behavioral problems. Mice aren’t perfect for modelling human brains, and no huntingtin-lowering drug would remove the protein completely - but this research supports the need for continued caution as we test drugs that lower normal huntingtin.
A new exciting chapter in Huntington’s disease (HD) treatment is just beginning – WAVE Life Sciences have announced PRECISION-HD1 and 2, clinical trials of two new drugs that lower the mutant Huntington’s disease protein. We’re excited about this novel approach to huntingtin lowering therapies, but these are early days and we’ve got a long way to go to show they’re safe and effective in people.
