Active clinical trials for "Huntington Disease"

Primary objective: The primary objective of the study is to establish that riluzole slows down (1) the decrease in total functional capacity (TFC), (2) the increase of the motor score of the Unified Huntington's Disease Rating Scale (UHDRS) as well as (3) the increase of a combined score of these. Secondary objectives: Secondary objectives are to assess changes in the other UHDRS subscales the number of patients who need antichoreic treatment and the time until this treatment has to be initiated the safety/tolerability of riluzole in Huntington patients

This study, CREST-HD, will examine the safety and tolerability of 8 grams of creatine in subjects affected by Huntington's disease (HD). Biochemistry and neuroimaging will be used to examine the potential effects of creatine on HD.

The purpose of the study is to evaluate the efficacy of exogenous melatonin in improving sleep quality in HD gene carriers.

This study is a multi-center, open-label study of intravenous (IV) ANX005 in subjects with, or at risk for, manifest Huntington's Disease (HD).

Study BP40410 is an open-label, adaptive multiple-dose clinical study designed to characterize the PK of RO7234292 (RG6042) in plasma and CSF as well as the acute time course and recovery profile of CSF mHTT lowering in response to RO7234292 (RG6042) treatment after intrathecal (IT) administration of RO7234292 (RG6042) to patients with manifest Hungtington's disease (HD).

This study will evaluate the efficacy, safety, and biomarker effects of RO7234292 (RG6042) compared with placebo in participants with manifest Huntington's disease (HD).

The purpose of this study is to assess efficacy and safety of dextromethorphan/quinidine 20mg/10mg (DM/Q 20mg/10mg) in patients with irritability due to Huntington's disease.

Positron Emission Tomography (PET) is a functional imaging technique, which enables in vivo visualization of biological molecules expressed in human tissues. Brain PET is most powerful to study a vast range of neurological and psychiatric disorders in vivo, targeting neuronal and glial activity, metabolism, cerebral blood flow, receptor proteins or misfolded proteins. In vivo imaging of synaptic density in the human brain has become feasible through development of [11C]UCB-J, a PET radioligand for the synaptic vesicle protein SV2A, which is ubiquitously and homogeneously present in presynaptic terminals throughout the brain. A first study in Huntington's disease (HD) mutation carriers showed loss of striatal [11C]UCB-J binding (also when corrected for atrophy), as well as in the neocortex (Delva et al, Neurology 2022). Moreover, regional synaptic loss was highly correlated to motor impairment. In order to be able to use SV2A PET as widespread available biomarker tool to assess synaptic integrity, disease progression and/or response to mHTT lowering drugs, the short half-life of 11C (20 minutes) for [11C]UCB-J remains a hurdle. Recently, [18F]SynVesT-1, an optimized 18F-labeled analogue of [11C]UCB-J with similar kinetics, binding affinity, and test-retest precision properties has been evaluated in humans. However, there is evidence from preclinical studies conducted at University of Antwerp that in the zQ175DN knock-in mouse model of HD, larger variability and lower effect-sizes are seen with [18F]SynVest-1 than with [11C]UCB-J. In order to ascertain a similar effect size and quantification properties for [18F]SynVest-1 and [11C]UCB-J PET in human HD, both in the premanifest and manifest phase, and to validate simplified measures (such as SUVR with white matter as reference region) and SynVest, this head-to-head fully quantitative study is performed.

The primary objective of this study is to discover blood-based biomarker of brain Huntingtin (HTT) protein using extracellular vesicles to be used in evaluating target engagement in HTT lowering clinical trials. Secondary objectives of this study include developing more accurate biomarkers of Huntington disease (HD) progression or conversion and to develop standard practices for extracellular vesicle biomarker discovery research. The investigators hypothesize that brain-derived extracellular vesicles (EVs) isolated from human biofluids contain biological cargo specific to their tissue of origin that could allow their use as brain biomarkers for HD. EVs are lipid bilayer-delimited particles that are naturally released from cells in the brain. The investigators will investigate if EVs contents reflect the pathological alterations occurring with disease progression when compared with EVs isolated from biofluids of healthy non-HD persons.

This study tested the safety, tolerability, pharmacokinetics and pharmacodynamics of multiple ascending doses of ISIS 443139 administered intrathecally to adult participants with early manifest Huntington's Disease.
