Efficacy and Safety of Astragalus for Non-motor Symptoms of α-Synucleinopathy

Phase 2
Recruiting
Conditions
Parkinsonism
Interventions
Behavioral: Physical therapy group
Drug: Astragalus
Registration Number
NCT05506891
Lead Sponsor
Fujian Medical University Union Hospital
Brief Summary

α-Synucleinopathy is a cluster of neurodegenerative disease with motor and non-motor symptom. However, there is still a lack of research on the treatment for non-motor symptoms of α-synucleinopathy, especially autonomic dysfunctions such as orthostatic hypotension. Efficacy and safety of astragalus for non-motor symptoms of α-synucleinopathy will be assessed by an open-label self-controlled before-and-after study.

Primary Outcome Measures
NameTimeMethod
Change from baseline mean arterial pressure after 3 minutes of upright posture versus decubitus position (mmHg) at 3 months.Baseline vs 3 months after treatment.

Mean arterial pressure was calculated as ⅓ pulse pressure + diastolic pressure.

Secondary Outcome Measures
NameTimeMethod
Change from baseline decumbent and orthostatic digit span (DDS) difference at 3months.Baseline vs 3 months after treatment.

DDS is an executive function measurement tool

Change from baseline HRV (ms) at 3months.Baseline vs 3 months after treatment.

Heart rate variability (HRV) was calculated as the maximum bpm - minimum bpm.

Change from baseline HDS scores at 3 months.Baseline vs 3 months after treatment.

The Hamilton Depression Scale (HDS)

Change from baseline CDR scores at 3 months.Baseline vs 3 months after treatment.

The Clinical Dementia Rating (CDR)

Change from baseline HAS scores at 3 months.Baseline vs 3 months after treatment.

The Hamilton Anxiety Scale (HAS)

OH Questionnaire scoreBaseline vs 3 months after treatment.

ΔHR/ΔSBP means heart rate (HR) and systolic blood pressure (SBP) from baseline OH Questionnaire score

Change from baseline decumbent and orthostatic character conversion (CDS) difference at 3months.Baseline vs 3 months after treatment.

CDS is an executive function measurement tool

Change from the baseline plasma α-synuclein levels (ng/ml) at 3 months.Baseline vs 3 months after treatment.
Change from baseline ODI at 3 months.Baseline vs 3 months after treatment.

NODDI models the dispersion of axonal fibers with the use of an Orientation Dispersion Index (ODI).

Change from baseline Rate of change in ΔHR/ΔSBP at 3months.Baseline vs 3 months after treatment.

ΔHR/ΔSBP means heart rate (HR) and systolic blood pressure (SBP) from baseline lying position to standing for 3 minutes

Change from baseline MoCA scores at 3 months.Baseline vs 3 months after treatment.

The Montreal Cognitive Assessment (MoCA)

Change from baseline RAVLT scores at 3 months.Baseline vs 3 months after treatment.

The Rey Auditory Verbal Learning Test (RAVLT)

Change from baseline NPI scores at 3 months.Baseline vs 3 months after treatment.

The Neuropsychiatric Inventory (NPI)

Change from baseline Vic at 3 months.Baseline vs 3 months after treatment.

The intra-cellular compartment (Vic) of the Neurite Orientation Dispersion and Density Imaging (NODDI) model represents diffusion within the axons and cells.

Change from baseline PAF (Hz) at 3 months.Baseline vs 3 months after treatment.

The alpha-peak frequency (PAF) is the frequency with the highest power within the alpha-band.
