About this study

Official title: A Single Center, Open-label Study to Evaluate the Safety, Tolerability and Preliminary Efficacy of Allogeneic Dopaminergic Neural Precursor Cell(iDAP) Injection in the Treatment of Parkinson's Disease

The goal of this clinical trial is to evaluate the safety, tolerability and preliminary efficacy that iDAP has on Parkinson's disease (PD) patients.

Read the detailed description

Parkinson's disease (PD) is a common neurodegenerative disease in the middle-aged and elderly. It is the "third killer" of the middle-aged and elderly after tumors and cardiovascular and cerebrovascular diseases. Its main clinical manifestations are resting tremor, reduced voluntary movement, muscle rigidity, postural reflex impairment, and autonomic dysfunction, which seriously affect patients' work ability and quality of life. It is estimated that nearly 100,000 people in China become new Parkinson's patients every year. Experts from the World Health Organization predict that the number of Parkinson's patients in China will reach 5 million in 2030, which will be more than half of the world's total. As the disease progresses, the symptoms of Parkinson's patients will become increasingly severe. The high prevalence and high disability rate of Parkinson's disease bring heavy burdens to individuals, families, and society.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence and severity of adverse events.

    Safety and tolerability

    Measured: Within 24 months post-transplantation

Secondary outcomes (8)
  1. Assessment of changes in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), part III, in comparison with baseline values.

    Minimum score: 0; Maximum score: 132; Higher scores mean a worse outcome.

    Measured: Within 24 months post-transplantation

  2. Assessment of changes in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), part I,II,IV, in comparison with baseline values.

    Higher scores mean a worse outcome.

    Measured: Within 24 months post-transplantation

  3. Assessment of changes in Hoehn & Yahr scale in comparison with baseline values.

    Comprehensive clinical assessment for examining the improvements in Parkinson disease.

    Measured: Within 24 months post-transplantation

  4. Assessment of changes in Mini-mental State Examination (MMSE), Hamilton Depression Scale (HAMD)-17 and Hamilton Anxiety Scale (HAMA)-14 in comparison with baseline values.

    Comprehensive clinical assessment for examining the improvements in mental state.

    Measured: Within 24 months post-transplantation

  5. Assessment of changes in Activity of Daily Living Scale (ADL) in comparison with baseline values.

    Comprehensive clinical assessment for examining the improvements in activity of daily living.

    Measured: Within 24 months post-transplantation

  6. Brain network connectivity patterns as demonstrated on positron emission tomography(PET) compared with baseline in the 'off' state.

    Evidence of cell survival

    Measured: Within 24 months post-transplantation

  7. Brain DAT intake index as demonstrated on PET dopamine transporter(DAT) compared with baseline in the 'off' state.

    Evidence of cell survival

    Measured: Within 24 months post-transplantation

  8. Patient L-dopa equivalent dose compared with baseline.

    Measure of dopaminergic drug dose.

    Measured: Within 24 months post-transplantation

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Allogeneic dopaminergic neural precursor cell(iDAP) in people with Parkinson Disease, run by Anhui Provincial Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 4 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jiong Shi, M.D (6228 3114, Jshi2022@ustc.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and severity of adverse events. (time frame: Within 24 months post-transplantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2024.
