Huntington’s disease research news. In plain language. Written by scientists. For the global HD community.
Pfizer has announced that the first-pass analysis of its 'Amaryllis' trial, testing a PDE-10 inhibitor drug, shows the drug did not meet its target of improving Huntington's disease symptoms. As a result, the open-label extension study will be stopped. This is not the news we'd been hoping for, but we've learned a lot about HD along the way.
A recent press release from Teva Pharmaceuticals has the HD community excited, claiming "Pridopidine Demonstrates Slowing of Progression of Huntington Disease in PRIDE-HD Study". What's pridopidine, and what can we really say about HD progression in patients treated with it?
Everyone with Huntington's disease has inherited the same type of mutation from their mother or father, an extra-long repetitive stretch of the sequence C-A-G in their HD gene. But the length of the mutation varies between individuals, and longer repeats are associated with earlier onset of symptoms. A huge new international study reveals that slightly longer-than-normal CAG stretches are much more common than we thought. Surprisingly, this turns out to be good news.
Nearly a thousand HD family members converged on Baltimore, Maryland for the 2016 Huntington’s Disease Society of America’s Annual Convention. We normally don’t write reports from patient and family conferences, but there was something special about the atmosphere of this year’s Convention that compelled us to pen a brief update.
A recent article in the UK newspaper the Daily Telegraph has HD families very excited. The title, "First drug to reverse Huntington’s disease begins human trials", certainly sounds exciting! But what's really going on? HDBuzz is here to help us untangle hope from hype in the huntingtin lowering world.
The third and final day of the 2016 Huntington's Disease Therapeutics Conference brings updates on cell replacement therapies including stem cells; and new ways to assess and model the progression of HD to help understand it and run crucial clinical trials.
New therapies for disorders like Huntington’s disease are on the way, but getting the drugs to enter brain cells can be a major challenge. A group of scientists has redesigned and tested a harmless virus that can efficiently deliver a 'gene silencing' message throughout the brain in mice, much further than naturally occurring viruses can reach. What's more, it can be given with a simple injection into the blood, offering great potential for research in gene silencing research and beyond.
Today brings news that the first Huntington's Disease patients have been successfully dosed with gene silencing drugs targeting the HD gene. These brave volunteers are the first HD patients to ever be treated with drugs designed to attack HD at its root cause, a treatment approach with huge potential. What about this news has us so excited?
Even though every patient with Huntington's Disease has a mutation in the same gene, the age at which HD patients develop symptoms varies widely. A global consortium of HD researchers has just published a landmark study of genetic differences between people that might explain some of that variability, producing some tantalizing new targets for drug discovery efforts.
