Multiple System Atrophy - Parkinsonian Subtype (MSA-P)

This clinical trial is designed to evaluate the safety, tolerability and preliminary efficacy of a single injection of NouvNeu001 (Human Dopaminergic Progenitor Cells Injection) in patients with Multiple System Atrophy.

This study is an observational, prospective genetic study. It aims to obtain DNA for research and testing from patients with PSP, CBS, MSA, and related neurological conditions and their families. Up to 1,000 adults who have been clinically diagnosed with PSP, CBS, MSA, or related neurological conditions will be enrolled. The study intervention involves sequencing of participant blood samples using non-CLIA-approved whole genome sequencing at the National Institutes of Health. Pathogenic variants that are deemed possibly related to these conditions will be confirmed using CLIA-approved testing. The study involves minimal risk to participants.

The PD-HemON study aims to evaluate the safety and preliminary efficacy of ARC-IM Therapy (Epidural Electrical Stimulation) to support hemodynamic management in people with typical and atypical Parkinson's Disease, who suffer from orthostatic hypotension.

This is a single-center, prospective, randomized, open-label, blinded outcome assessment (PROBE) study. At the end of the PROBE study, patients who have completed the study may opt to enter the open-label extension (OLE) study. The objective of the study is to evaluate the safety, tolerability and potential preliminary efficacy of Aleeto in the treatment of patients with multiple system atrophy (MSA).
