2. Patients must have screened for the HBPD03 clinical trial entitled, "A Randomized, Double-Blind, Single Center, Phase 2, Efficacy and Safety Study of autologous HB-adMSCs vs Placebo for the Treatment of Patients with Parkinson's Disease" under IND 027396.
3. Patients must have not been randomized into the treatment group for the HBPD03 clinical trial entitled, "A Randomized, Double-Blind, Single Center, Phase 2, Efficacy and Safety Study of autologous HB-adMSCs vs Placebo for the Treatment of Patients with Parkinson's Disease" under IND 027396.
4. Male and female participants 18 - 80 years of age.

3. Patients with medical history of uncontrolled high blood pressure defined as a deficient standard of care treatment and/or blood pressure > 150/90 mm/Hg during screening visit.

4. Patients with the following concomitant or past medical history:

   • Heart Failure - New York Heart Association (NYHA) Class III/IV.
   • Heart Attack (in the past six months before 1st infusion).
   • Stroke (in the past six months before 1st infusion).
   • Hepatitis B or C.
   • Human immunodeficiency virus (HIV) infection.

5. Any of the following abnormal lab findings during screening will disqualify a patient from this expanded access protocol:

   • Hemoglobin (Hgb) <10 G/DL or >18 G/DL
   • Hematocrit (HCT) <30% or >55%
   • Platelet count < 80 K/UL and or > 450 K/UL.
   • White blood cell count WBC < 3.0 K/UL and > 13.0 K/UL.
   • Alanine aminotransferase (ALT) of > 75 IU/L
   • Aspartate aminotransferase (AST) of > 75 IU/L
   • eGFR < 40 mL/min/1.73
   • Pre-prandial glucose > 150 MG/DL
   • Post-prandial glucose > 200 MG/DL

6. Patients who have received any stem cell treatment in the past six months before 1st infusion other than stem cells produced by Hope Biosciences.

7. Patients who are unlikely to complete the visits or adhere to the procedures.

8. The patient has previously been diagnosed with a psychiatric disorder, which is currently uncontrolled.

9. Patients with a history of addiction or dependency or currently abusing or using substances.

11. Patients who have received an experimental drug in the past 12 months before the first dose of the investigational product. (Except for COVID-19 vaccinations).

12. Patients who the Investigator determines to be unsuitable for participation for other reasons, such as, but not limited to deep vein thrombosis (DVT), pulmonary embolus, cardiac arrhythmia, or those who have a prothrombotic condition, or who require persistent oxygen supplementation.
