Prevail Therapeutics PR001 Gene Therapy Trials

(October, 2020)

Prevail Therapeutics is developing an investigational gene therapy called PR001 that has the potential to slow or stop the underlying disease process in patients with Parkinson’s disease with GBA1 mutations (PD-GBA) and neuronopathic Gaucher disease (nGD).

PD-GBA and Gaucher disease share the same underlying mutation of a gene, called GBA1. PD-GBA patients have mutations in at least one of their two copies of the GBA1 gene, while Gaucher disease patients have mutations in both GBA1 copies. The GBA1 gene contains the instructions for making the protein beta-glucocerebrosidase, or GCase.  GCase works in a compartment inside of cells called the lysosome, where it is responsible for the disposal and recycling of glycolipids (a type of fat). When there is an insufficient amount of active GCase, the lysosome does not function normally, which can lead to the symptoms seen in PD-GBA and nGD.

In order to deliver the healthy GBA1 gene to cells of the brain, PR001 uses a viral vector (or shuttle) called AAV9. AAV9 is a well-studied vector used by a number of companies developing gene therapy products, particularly those that target disorders of the nervous system.  The therapy is designed to enable brain cells to produce enough active GCase for lysosomes to do their jobs and potentially slow or stop the disease from progressing.

In clinical trials, PR001 is administered by a one-time injection into the cerebrospinal fluid space in an area above the spinal cord called the cisterna magna. This type of injection is a direct, non-surgical technique that has been used safely for other purposes for many years.

Parkinson’s Disease with GBA1 Mutations (PD-GBA)

Parkinson’s disease with GBA mutation (or PD-GBA) starts earlier compared to Parkinson’s disease in patients without this genetic mutation, with more severe symptoms and increased likelihood of dementia. It is estimated that as many as seven to ten percent of patients with PD worldwide, including some 90,000 patients in the United States, have at least one GBA1 mutation1.

Physicians and researchers can use patients’ genetic information — such as whether or not a patient carries a GBA1 mutation — to assist in diagnosis. This may also help to identify clinical trials of new potential therapies in development for which a patient might be eligible.

Prevail is recruiting patients for PROPEL, a Phase 1/2 clinical trial designed to evaluate the safety and effects of PR001 in patients with moderate to severe Parkinson’s disease who have at least one GBA1 mutation. Twelve study participants are sought for this Phase 1/2 trial, which is being conducted at several clinical sites. Don’t know if you have a mutation? Prevail offers programs for genetic testing at PROPEL clinical sites.

Learn more about the PROPEL clinical trial or contact the Prevail PROPEL recruitment team with questions or to express interest in study participation.

Type 2 (neuronopathic) Gaucher disease

Gaucher disease has three types, which vary by severity of symptoms, age of onset and the presence of symptoms that affect the brain. Type 2 and Type 3 Gaucher disease are known as neuronopathic forms of the disorder because they are characterized by symptoms that affect the brain.

Type 2 Gaucher disease, the most severe form, affects infants. It causes rapid, progressive and irreversible brain damage usually beginning in the first six months of life; children typically die by age two. Patients with Type 2 Gaucher disease are also affected by the symptoms of Gaucher disease that occur throughout the body, such as spleen and liver enlargement and blood abnormalities.

Prevail is recruiting patients for PROVIDE, a Phase 1/2 clinical trial designed to evaluate the safety and effects of PR001 in infants 0-24 months of age with Type 2 Gaucher disease. Fifteen study participants are sought for this trial that will be conducted at several clinical sites.

Study Examining In-Utero Treatment of Gaucher Disease Types 2 and 3

The Univeristy of California San Francisco is conducting a study examining in utero treatment for nGD. Currently, children with Gaucher disease can be treated with enzyme replacement therapy (ERT) after birth, which slows the progress of the disease.

The clinicians conducting the study believe that giving ERT before birth could help patients with Gaucher even more. They have studied mice with a different lysosomal storage disease, Mucopolysaccharidosis type 7, and gave them ERT before birth. Mice treated with ERT before birth had better outcomes than mice treated with ERT after birth.

They are initiating a clinical trial to give ERT to fetuses with several lysosomal storage diseases, including Gaucher Types 2 and 3. The possible benefits of giving ERT before birth are avoiding the development of antibodies to the enzyme, crossing the blood brain barrier, and preventing the disease from starting to cause damage to the brain and other organs.

Engaging the patient community is crucial in developing novel therapies. As such, they are surveying Gaucher parents’ and patients’ attitudes towards fetal therapy.

The survey includes an introduction to the project as well as consent. If you have questions please contact Dr. Marisa Schwab.

Parkinson’s Progression Markers Initiative

Be part of the Genetics Research Revolution in Parkinson’s Disease

Individuals with Gaucher disease and those with Parkinson’s disease (PD) can share a common link: mutations in the GBA gene. Identifying and evaluating people who carry a GBA mutation, whether they have Gaucher disease or PD or are related to someone living with one of these diseases, is vital to helping scientists learn more and develop improved treatments.

The Parkinson’s Progression Markers Initiative (PPMI) is a landmark clinical study sponsored by The Michael J. Fox Foundation to better understand the progression of and risk factors for PD.

PPMI is currently studying the connection between PD and mutations in the GBA gene.

Individuals of Eastern European (Ashkenazi) Jewish descent are more likely than the general population to carry a mutation in the GBA gene. PPMI provides genetic counseling and testing for GBA mutations at no cost to individuals of Ashkenazi Jewish descent who:

  • Have Gaucher disease and are age 45 or older
  • Do not have Gaucher disease but are age 45 or older and have a first-degree relative with Gaucher disease
  • Have PD and are age 18 or older
  • Do not have PD but are age 45 or older and have a first-degree relative with PD

Clinical Study on Parkinson Disease and Deep Brain Stimulation Seeks Participants

Participants sought for clinical study about the level of cognitive decline experienced by patients who have Parkinson disease and are treated with Deep Brain Stimulation (DBS). Parkinson disease affects at least 1 million people in the U.S. Each year, 9,000 Parkinson disease patients undergo deep brain stimulation placement; which improves their motor skills. Despite their motor improvement, up to 50% of patients have some level of cognitive (thought process) impairment after DBS. Carriers of mutations in the glucocerebrosidase (GBA) gene are at particularly high risk for cognitive impairment. This study seeks to determine the differences in cognitive decline between patients with Parkinson disease who are carriers of the GBA gene mutation as compared to Parkinson patients who are carriers of the GBA gene mutation without previous therapy with deep brain stimulation as well as non-mutation carriers with and without deep brain stimulation. Understanding if there is an association between the GBA gene and DBS will enable clinicians to identify individuals at risk for worsened cognitive dysfunction and prevent additional harm.
