Active clinical trials for "Multiple System Atrophy"

This will be an observational study looking at clinical and biomarker characteristics in patients with Parkinson's Disease (PD), Multiple System Atrophy (MSA), Rapid Eye Movement Sleep Behavior Disorder (RBD), Normal Pressure Hydrocephalus and matched controls. Saliva, plasma, serum, urine, and cerebrospinal fluid (CSF) samples will be collected from participants.

Single-center, randomized, placebo-controlled, phase-II, futility clinical trial to determine if oral sirolimus is of sufficient promise to slow disease progression in MSA, prior to embarking on a large-scale and costly phase III study to assess its efficacy. A futility design under the null hypothesis assumes that sirolimus will slow the progression of the disease, whereas the alternative hypothesis assumes no benefit of sirolimus. If the null hypothesis is rejected (i.e., futility of sirolimus to slow progression of MSA), a major phase III study will be discouraged, whereas non-futility will offer strong support for a phase III trial to detect clinical efficacy.

The purpose of this study is to determine safety and tolerability of the treatment with lithium in Multiple System Atrophy. Moreover, clinical symptoms, neuronal loss, quality of life and depressive symptoms, will be considered to further investigate the effect of lithium therapy.

The purpose of this study is to learn more about the regulation of the veins of the abdomen by the autonomic (involuntary) nervous system, and how this may affect high blood pressure. Normally, the autonomic nervous system controls how much blood flows in the veins. In people with high blood pressure, however, the autonomic nervous system is changed. This change may affect the way blood flows in the veins of the abdomen which may play a role in their high blood pressure. About 32 participants will be screened for the study. The investigators estimate 16 will be eligible to participate in all of the study days.

The investigators aim to learn more about symptoms suggestive of a neurodegenerative process.

This study will enroll participants with idiopathic rapid eye movement (REM) sleep behavior disorder (RBD), for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.

The aim of the study is to evaluate the effects on motor and cognitive performance of transcranial alternating current stimulation (tACS) compared to transcranial direct current stimulation (tDCS) and placebo stimulation (sham) in patients with neurodegenerative ataxia to identify a possible rehabilitation protocol.

In total 20 subjects will be enrolled at one participating site -UMC Ljubljana. The 20 subjects will be treated with placebo and NBMI 300 mg in a cross-over design. In case of subject drop-outs, additional subjects may be enrolled as decided by the Sponsor, to allow for expected number of evaluable subjects in each group.

The purpose of this study is to compare the efficacy of verdiperstat (BHV-3241) versus placebo in participants with Multiple System Atrophy

The purpose of this study is to assess the durability of effect of Droxidopa in treating symptoms of neurogenic orthostatic hypotension in patients with Primary Autonomic Failure (Pure Autonomic Failure, Multiple System Atrophy, Parkinson's Disease), Non-diabetic neuropathy, or Beta Hydroxylase deficiency.
