Outcome Measures

Primary Outcomes (2)

  • Incidence of dose limiting toxicity (DLT) events

    To evaluate the rate of incidence of DLT events determined by the Safety Data Review Committee (SRC) in DLT observation period after injecting BBM-P002

    Within 4 weeks

  • Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)

    To evaluate the safety of BBM-P002 by AEs and SAEs.

    Within 4 weeks

Secondary Outcomes (9)

  • Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Within 5 years

  • Changes in the titers of neutralizing antibodies and binding antibodies in the recombinant adenovirus capsid of blood

    Within 5 years

  • Changes in the results of the cranial MRI scan

    Within 5 years

  • Changes from baseline in MDS - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) I/II/III/IV scores

    Within 5 years

  • Changes from baseline in the Patient Global Impression of Improvement (PGI-I) scores

    Within 5 years

  • +4 more secondary outcomes

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants with a diagnosis of Parkinson's disease for ≥ 5 years.
