New gene therapy for early-onset Parkinson’s

Nearly one million people in the U.S. are living with Parkinson’s disease, which causes progressive symptoms including tremors, stiffness, and gait and balance issues. Although there are medications to treat symptoms, the disease has no cure. 

CIRM’s support for potential Parkinson’s treatments

To date, the California Institute for Regenerative Medicine (CIRM) has invested more than $109 million in helping research for Parkinson’s disease progress from a basic or Discovery level through clinical trials.

The most recent investment is a $2.5 million award to Jennifer Johnston, PhD, CEO of NysnoBio GT Neurology. The funding will support the development of a gene therapy approach to deliver a healthy version of the Parkin gene to patients whose disease is caused by a mutation in that gene.  

Early-onset Parkinson’s

In many cases the cause of Parkinson’s disease is not known, but almost half of those who have family members with the disease and who develop symptoms before 45 years-old carry a mutation in the Parkin gene.  

When it is functioning properly, the Parkin protein helps cells recycle damaged proteins. This plays a key role in maintaining the cell’s mitochondria, particularly within a group of neurons involved in Parkinson’s disease. In people with a Parkin gene mutation, damaged mitochondria accumulate. This in turn impairs a cell’s function. If successful, the gene therapy approach would allow these cells to produce a healthy Parkin protein and reverse effects of the disease.  
 
“This gene therapy approach represents a promising strategy to restore Parkin function and mitochondrial health in this early-onset form of Parkinson’s disease,” said CIRM Senior Science Officer Lisa McGinley, PhD.

By targeting a genetically validated mechanism, it has the potential to offer a therapy that goes beyond current standards of care, McGinley said. It may also have broader application to other neurodegenerative disorders.
 
“NysnoBio is honored to be awarded this prestigious grant from CIRM. (The) funding is critical to advance pioneering therapies to cure human disease,” said Dr. Johnston. “CIRM is a uniquely steadfast supporter of cell and gene therapies. This removes roadblocks and creates efficiencies. (It helps) ensure integration of new therapeutic modalities into the healthcare arsenal against human disease and suffering.”  
 
The funded project is not yet being tested in people. It is considered a translational grant, which means that the funding will help move a promising idea closer to FDA approval for clinical trials.
