Abstract (original English)

Objective This intermediate-size expanded access program aimed to evaluate safety and clinical efficacy of multiple intravenous infusions of autologous, Hope Biosciences adipose-derived mesenchymal stem cell (HB-adMSC) therapy in elderly patients with Parkinson's disease (PD). Methods Ten eligible participants (aged 76-95 years) received six intravenous infusions each with 200MM autologous HB-adMSCs over 18 weeks, with the end of study (EOS) at week 26. Safety was assessed through adverse events (AEs) and serious adverse events (SAEs). Efficacy was measured through improvements in both motor and non-motor symptoms, utilizing scales including Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) parts I-IV, Parkinson's Disease Questionnaire-39 (PDQ-39), Parkinson's disease Fatigue Scale (PFS-16), Patient Health Questionnaire-9 (PHQ-9), and Visual Analog Scale (VAS). Analysis employed paired t-tests and Minimal Clinically Important Difference (MCID) thresholds for the patient-reported outcomes. Results Most AEs (37 out of 46) were mild in severity, with 5 SAEs reported, none attributed to the drug. No deaths occurred. Despite lack of statistical significance across the efficacy endpoints, modest yet clinically meaningful improvements with effect size > 0.3 were observed in several secondary efficacy endpoints (MDS-UPDRS part I & III, PDQ-39, and PHQ-9) at
