Novel Gene Therapy to Treat L-DOPA-Induced Dyskinesia

Viral vector injections of rAAV-∆FosB shRNA significantly reduced abnormal involuntary movements (AIMs) compared to control vector in a rat model of Parkinson’s disease.

Invention Summary:

Parkinson's disease (PD) is a progressive, debilitating, and currently incurable neurodegenerative disease. Long-term dopamine replacement therapy in PD leads to the development of abnormal involuntary movements known as L-DOPA–induced dyskinesia (LID). Alleviating this dyskinesia can lead to significant improvements in quality of life for patients with PD.

The transcription factor ∆FosB plays an important role in the development of dyskinesias and is a candidate target for gene therapy strategies to control LID. Scientists at Rutgers and Emory University have shown that lowering ∆FosB expression via gene silencing is an effective and feasible therapeutic approach to improve LID. Injection of a rAAV-∆FosB shRNA viral vector significantly reduced dyskinesia in a rodent PD model compared to controls. These effects were achieved while maintaining the antiparkinsonian action of L-DOPA, indicating that this gene therapy can successfully be used to treat dyskinesia in patients with advanced PD.

Market Applications:

  • Gene therapy
  • Treatment for LID/severe dyskinesia


  • Highly effective at improving LID
  • Can be used in tandem with other PD drugs
