About this study

Official title: exPDite-2: A Phase 3 Study to Assess the Efficacy and Safety of Midbrain Dopaminergic Neuronal Cell Therapy (Bemdaneprocel) for Participants With Parkinson's Disease

Study BRT-DA01-301 is a Phase 3 multicenter, randomized, sham surgery-controlled, double-blind study to assess efficacy and safety of bemdaneprocel in approximately 102 adults with Parkinson's Disease (PD).

Read the detailed description

The BRT-DA01-301 study is a Phase 3, multicenter, randomized, sham surgery-controlled, double-blind study involving approximately 102 participants with Parkinson's Disease (PD). Participants will be randomized in a 2:1 ratio to either receive bemdaneprocel or undergo sham surgery. The study includes an immunosuppression regimen and placebo equivalents to maintain blinding. The primary objective is to evaluate the efficacy of bemdaneprocel on motor symptoms in participants with PD. The secondary objective is to evaluate the effects of bemdaneprocel on Motor function, Quality of life, Non-motor symptoms of PD, Disease severity, and Use of PD medications or therapies compared with participants who undergo sham surgery. Participants will be followed for at least 18 months in the double-blind period and up to five years if they receive bemdaneprocel.

What is being measured

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

  1. Change from baseline in PD diary measure of ON-time without troublesome dyskinesia, adjusted for a 16-hour waking day

    Measured: From baseline to Week 78

Secondary outcomes (6)
  1. Change from baseline in PD diary measure of OFF-time, adjusted for a 16-hour waking day

    Measured: From baseline to Week 78

  2. Change from baseline in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III score in the off-medication state. Part III score can range from 0 to 132, with lower scores being better.

    Measured: From baseline to Week 78

  3. Change from baseline in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II score. Part II score can range from 0 to 52, with lower scores being better.

    Measured: From baseline to Week 78

  4. Percentage change from baseline in 18F-DOPA uptake in the posterior putamen.

    Measured: From baseline to Week 78

  5. Change from baseline in Parkinson's Disease Questionnaire-39 (PDQ-39) summary index. Summary index score can range from 0 to 100, with lower scores being better.

    Measured: From baseline to Week 78

  6. Incidence and severity of treatment-emergent adverse events

    Measured: From baseline to month 60

Model description
In the double-blind period, participants will be randomized at a 2:1 ratio to either receive bemdaneprocel or undergo sham surgery. Participants will receive immunosuppression or placebo equivalents for approximately 12 months. Approximately 18 months after the last participant is enrolled and based on the results of the primary analysis and review by the independent data monitoring committee (DMC), eligible participants who underwent sham surgery and remain actively enrolled in the study will have the opportunity to receive bemdaneprocel in the open-label period.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing bemdaneprocel in people with Parkinsons Disease (PD), run by BlueRock Therapeutics at 43 sites in 3 countries.

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 8 inclusion and 13 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: looking for participants now, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 43 sites in United States, Australia, Canada. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Patient Engagement (1-877-380-3967, clinicaltrials@bluerocktx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in PD diary measure of ON-time without troublesome dyskinesia, adjusted for a 16-hour waking day (time frame: From baseline to Week 78). 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 2 Nov 2026.
