Enrollment Closed: Phase 1 Clinical Trial for Advanced Parkinson’s Disease

In May 2022, enrollment was closed for the Phase 1 clinical trial to test if the investigational medicine BRT-DA01 is safe and improves symptoms in patients with advanced Parkinson’s disease (PD).

Eligibility Criteria:

This study is for patients with advanced Parkinson’s disease who meet certain criteria including:

  • Aged: 60-78 in the U.S.; 50-78 in Canada.
  • Diagnosed with Parkinson’s disease between 3 and 20 years ago.
  • Regular Parkinson’s medications are no longer fully effective or have caused side-effects.
  • No previous surgical treatment for their Parkinson’s disease. (i.e., Deep Brain Stimulation).

For contacts and study locations, please go to clinicaltrials.gov. Identifier: NCT04802733

Study Description:

  • Patients will undergo surgery to transplant dopamine-producing cells into a part of the brain called the putamen, the area of the brain that regulates movement. Patients will be under general anesthesia.
  • Patients will then take medicines to partially suppress the immune system (aimed to prevent the body from rejecting the cells) for 1 year.
  • Safety, tolerability, evidence of cell survival (using MRI and PET scans of the brain), and effect on Parkinson’s disease symptoms are assessed for 2 years post-transplant.

*BRT-DA01 is an experimental product candidate and has not been approved by any regulatory agencies.  

Expanded Access Policy

An expanded access program (also known as EAP) and sometimes called “compassionate use,” is a potential pathway for a patient with an immediately life-threatening condition or serious disease to gain access to an investigational drug for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available. These investigational drugs have not yet been approved or cleared by regulatory bodies like the FDA, and these products have not yet been found to be safe and effective for their specific use.

We understand that some patients may wish to access our investigational drugs that have not yet been approved. At this stage of drug development and trials, we do not have enough clinical product or evidence of clinical safety and efficacy of our investigational drugs to support expanded access. Therefore, BlueRock Therapeutics does not currently offer an expanded access program at this time. The most appropriate way for patients to access our investigational drug is by participating in our clinical trials, and we encourage you to speak with your doctor about whether you would qualify for this trial. Information regarding ongoing clinical trials can be accessed at www.clinicaltrials.gov. (Identifier: NCT0480273)

In accordance with the 21st Century Cures Act, this policy may be revised at any time. If you have additional questions about BlueRock’s expanded access policy, please speak to your physician, or contact regulatory@bluerocktx.com.  We will make our best effort to respond within 5 days.
