Scientists have figured out the first molecular events in the formation of toxic huntingtin protein clumps in Huntington’s disease. The findings shed light about why only mutations that result in at least 36 repeats of glutamine (one of protein’s building blocks) in the huntingtin protein cause the disease —…

The oral therapy valbenazine significantly reduces involuntary muscle contractions, or chorea, and patient-reported disease burden in people with Huntington’s disease, according to results from the Phase 3 KINECT-HD clinical trial. Top-line data were announced by Neurocrine Biosciences, the therapy’s manufacturer, in 2021. The full findings have…

Austedo XR, an extended-release oral formulation of Austedo (deutetrabenazine), is now commercially available in the U.S. as a treatment for adults with chorea, or uncontrolled muscle contractions, associated with Huntington’s disease. The new formulation is available in tablet strengths of 6 mg, 12 mg, and 24 mg,…

The Phase 3 PROOF-HD trial failed to meet its main goal of showing that pridopidine, Prilenia Therapeutics’ experimental therapy, could slow functional decline compared with a placebo for adults with Huntington’s disease. However, preliminary top-line data indicated a potential slowing of disease progression among patients who were…

Asklepios Biopharmaceutical (AskBio) has launched a first-in-human clinical trial testing AB-1001 — an experimental gene therapy designed to modulate cholesterol metabolism in the brain — in people with Huntington’s disease. The trial is currently recruiting participants at a site in Paris. It is open to adults, ages 18…

A Phase 1/2a clinical trial testing VO659, Vico Therapeutics’ experimental therapy, in people with Huntington’s disease and other hereditary neurological disorders caused by a similar type of mutation has dosed the first patient. “We are encouraged by the continued progress of our development program and very pleased to…

Using machine learning, a form of artificial intelligence, researchers were able to cluster people with Huntington’s disease into three groups based on the speed at which the disease progresses, a study showed. “Machine learning approaches such as this could be considered for application in real-world clinical practice to support…

Austedo XR, a new extended-release formulation of Austedo (deutetrabenazine) has been approved by the U.S. Food and Drug Administration (FDA) to treat adults with chorea — involuntary muscle contractions — associated with Huntington’s disease. Austedo XR contains the same active agent as the original therapy, but is taken just once a day, with…

Treatment with antioxidant compounds called fullerenols showed neuroprotective effects in a fruit fly model of Huntington’s disease, particularly at early ages, according to a new study. These findings add to a number of studies highlighting the role of oxidative stress in Huntington’s, and suggest that fullerenols may have…

In Huntington’s disease, neurodegeneration in a brain region called the striatum differs not only across different types of neurons, but also across distinct striatal compartments, according to a study of brain samples from a Huntington’s patient and mouse models. The striosomes, the striatal compartment involved in regulating mood, was more…
