Gene therapy hope for severe Parkinson's patients
NCT ID NCT07371338
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests a gene therapy called IPS101A in 6 people with advanced Parkinson's disease (stages 4-5) whose symptoms are not controlled by current medications. The main goal is to check safety and find the best dose. Researchers will also look for any signs that the treatment helps with movement and daily function.

Inclusion Criteria: 1. Subjects who have a diagnosis of Parkinson's disease that meets the UK Parkinson's Disease Society Brain Bank Clinical Diagnostic Criteria at the time of the Screening Visit. 2. Male or female subjects aged 50 to 80 years (inclusive) at the time of providing written informed consent, with a documented diagnosis of Parkinson's disease. 3. Subjects with a duration of Parkinson's disease of at least 10 years prior to the Screening Visit, based on medical history and/or medical records. 4. Subjects with Parkinson's disease that is inadequately controlled despite all available standard-of-care treatments, including monotherapy or combination therapy, as determined by the Investigator. 5. Subjects with a Hoehn \& Yahr stage of 4 or 5 in the off state at the Screening Visit. Exclusion Criteria: 1. Subjects with Parkinson's disease dementia (PDD) who meet the diagnostic criteria established by the Movement Disorder Society (MDS) Task Force, as determined by the Investigator at Screening. 2. Subjects with a Korean Mini-Mental State Examination (K-MMSE) score ≤ 24 at the Screening assessment. 3. Subjects in whom imaging findings suggestive of Parkinsonism-plus syndrome are observed on PET and MRI performed at the Screening Visit, as assessed by the Investigator and/or a qualified imaging specialist. 4. Subjects who do not meet the diagnostic criteria for Parkinson's disease dementia but present with major visual hallucinations, as judged by the Investigator. 5. Subjects with drug-induced parkinsonism, confirmed by clinical history and/or medical records, and determined by the Investigator. 6. Subjects who are judged by the investigator to be unsuitable for participation in this clinical trial.
