About this study

Official title: An Exploratory Clinical Study to Evaluate UX-DA001 Injection (Human Midbrain Dopaminergic Progenitor Cells Injection) in Subjects With Idiopathic Parkinson's Disease

This clinical study is designed to explore the safety and tolerability of UX-DA001. It will also explore if UX-DA001 works to improve motor function in subjects with Parkinson's disease. UX-DA001 manufactured from participant's own cells will differentiate into mature dopaminergic neurons after being transplanted into the brain of the participant.

Read the detailed description

This study is an open-label, multi-center, dose-escalation and dose-expansion exploratory clinical study to evaluate the safety, tolerability, and potential efficacy of UX-DA001 Injection at different dose levels implanted in subjects with idiopathic PD.

Each subject receives only one dose of UX-DA001 for implantation into the putamen bilaterally using stereotactic neurosurgery under general anesthesia. Safety and tolerability of UX-DA001 and its effect on Parkinson's disease symptoms are assessed for 2 years post-treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • UX-DA001Biological

    UX-DA001 (Human Midbrain Dopaminergic Progenitor Cells) is used for treating patients with iPD via implanting into bilateral putamina under stereotactic neurosurgery.

    Two dose levels will be planned. Each patient only receives one corresponding dose of UX-DA001.

What is being measured

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

  1. The incidence and and severity of adverse events (AEs) associated with surgery and/or investigational product

    The incidence and and severity of adverse events (AEs) associated with surgery and/or investigational product during the surgical treatment period and the 4-week postoperative observation period.

    Number of participants with treatment-related adverse events as assessed by CTCAE v5.0.

    Measured: within 4 weeks post surgery

  2. The incidence and severity of AEs/serious adverse events (SAEs)

    The incidence and severity of AEs/serious adverse events (SAEs) during the study, including AEs and SAEs during the surgery treatment period, postoperative observation period, and follow-up period. Number of participants with treatment-related adverse events as assessed by CTCAE v5.0.

    Measured: From baseline to 2 years post surgery

Secondary outcomes (7)
  1. 18F-FP-CIT uptake using positron emission tomography (PET)

    Changes in 18F-FP-CIT uptake using positron emission tomography (PET) from baseline.

    Measured: From baseline to 2 years post surgery

  2. The situation of implantation and overgrowth of transplanted cells using cranial MRI

    Volume changes of transplanted cells using cranial magnetic resonance imaging (MRI)

    Measured: From baseline to 2 years post surgery

  3. Changes in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) score, part III, from baseline.

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

    Measured: From baseline to 2 years post surgery

  4. Changes in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) score, part II, from baseline.

    Minimum score: 0; Maximum score: 52; Higher scores mean a worse outcome.

    Measured: From baseline to 2 years post surgery

  5. Changes in modified modified Hoehn-Yahr (H&Y) scale from baseline

    Grade 0~Grade 5, lower grade means a better outcome

    Measured: From baseline to 2 years post surgery

  6. Changes in daily levodopa equivalent dose (LED) from baseline.

    Measured: From baseline to 2 years post surgery

  7. Changes in the scores of non-motor symptom scales (NMSS) from baseline.

    Minimum score: 0; Maximum score: 960; Higher scores mean a worse outcome.

    Measured: From baseline to 2 years post surgery

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing UX-DA001 in people with Parkinson Disease, Idiopathic, run by Shanghai UniXell Biotechnology Co., Ltd at 1 site in China.

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 10 inclusion and 18 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: under way, not looking for participants, as of the sponsor's last update on 11 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence and and severity of adverse events (AEs) associated with surgery and/or investigational product (time frame: within 4 weeks post surgery). The study lists 2 primary outcomes in all. 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 11 Jun 2026.
