• Registration Number: NCT05094011
• Lead Sponsor: Taiwan Mitochondrion Applied Technology Co., Ltd.

Brief Summary

Primary Objective: To assess the safety profile of autologous MitoCell administered to subjects with idiopathic Parkinson's disease (PD)

Secondary Objective: To explore the efficacy and safety of MitoCell given as the recommended dose by stereotactic intrastriatal implantation

Detailed Description

MitoCell is an autologous stem cell product that cultures with the company's unique patented medium. The mechanism of action of MitoCell is to improve the brain microenvironment in neurodegenerative disease. MitoCell which like mesenchymal stem cells modulate the immune response, and secrete more BDNF and SDF-1 neurotrophic factors than regular stem cell products.Therefore, MitoCell can protect and repair damaged dopamine neurons (DA) and stimulate DA regeneration.This project is a phase I open-label dose-escalation study to evaluate the safety, tolerability, and efficacy of autologous MitoCell intracranial transplantation in subjects with idiopathic Parkinson's disease which rating from stage 3 \~ 4 of modified Hoehn \& Yahr staging.

Secondary Outcome Measures

Name	Time	Method
PDQ-39 (Parkinson's Disease Questionnaire)	at 12, 24, 48 weeks	Change in PDQ-39 scale compared to the baseline. The PDQ-39 is a 39 questions Parkinson's Disease self-completed questionnaire that comprises 8 domains: mobility (10 items), activities of daily living (6 items), emotional well-being (6 items), stigma (4 items), social support (3 items), cognition (4 items), communication (3 items) and bodily discomfort (3 items). All items are assumed to impact QoL and must be answered to compute scores for each dimension. Questions are answered based on experiences from the preceding month using a 5-point ordinal scoring system: 0 = never, 1 = occasionally, 2 = sometimes, 3 = often, 4 = always. Each scores range from 0 = never have difficulty to 100 = always have difficulty.
Hamilton Depression Rating Scale (HAM-D-17) scores	at 48 weeks	Net change from baseline in HAM-D-17 scores. The HAMD-17 is a 17-item assessment used to assess the severity of depression and its improvement during the course of therapy. Each item was evaluated and scored using either a 5-point scale of 0 (not present/absent) to 4 (very severe) or a 3-point scale of 0 (not present/absent) to 2 (marked). Higher scores indicate greater symptom severity. The total score was the sum of the scores from HAMD-17 Items 1 through 17 and ranged from 0 (not at all depressed) to 52 (severely depressed).
Modified Hoehn & Yahr staging	at 12, 24, 48 weeks	Change in Modified Hoehn \& Yahr staging compared to the baseline.
Mini Mental State Examination (MMSE) Scores	at 48 weeks	Net change from baseline in MMSE scores. The MMSE uses a 30 point questionnaire to measure cognitive impairment. The MMSE is scored from 0 to 30,with a score equal to or greater than 24 points indicating normal cognition, a score of 19-23 points indicating mild cognitive impairment, 10-18 points indicating moderate impairment and a score equal to or below 9 indicating severe impairment.
MDS-UPDRS (Movement Disorder Society unified Parkinson's disease rating scale)	at 12, 24, 48 weeks	Change in MDS-UPDRS motor (Part III) "OFF" score compared to the baseline. All items have 5 response options with uniform anchors of: 0 = normal, 1 = slight (symptoms/signs with sufficiently low frequency or intensity to cause no impact on function), 2 = mild (symptoms/signs of frequency or intensity sufficient to cause a modest impact on function, 3 = moderate (symptoms/signs sufficiently frequent or intense to impact considerably, but not prevent function), 4 = severe (symptoms/signs that prevent function).
18F-DOPA PET	at 48 weeks	Degree of radiotracer uptake increment/decrement shown on striatum of 18F-DOPA PET compared to the baseline.
levodopa equivalent daily dose (LEDD)	at 12, 24, 48 weeks	Reduction of Parkinson's medications consumption by calculating levodopa equivalent daily dose (LEDD) compared to the baseline.
Beck Depression Inventory (BDI-II) scores	at 48 weeks	Net change from baseline in BDI-II scores. BDI-II Scale is a 21-item self-reported questionnaire which measures the existence and severity of symptoms of depression. Each of the 21 items on BDI-II tool represents a depressive symptom. The symptoms are each scored on a 4-point Likert scale of 0 to 3 (0=symptom is absent; 3=symptom is severe). Scores for each symptom are added up to obtain the total scores for all 21 items. Total score ranges from 0-63; of which 0-8 is considered no depression, 0-13 is minimal depression, 14-19 is mild depression, 20-28 is moderate depression and 29-63 is severe depression.
