Gene Therapy May Improve Parkinson’s Symptoms
Study Shows Improvement in Tremors After Injection of Genetic Material Into Brain
Gene Therapy vs. Sham Treatment continued...
Improvements in motor control were seen at one month and continued virtually unchanged throughout the six-month study, Kaplitt says.
"Although the mean improvement was relatively modest, half the subjects improved by over 9 points on the standard Parkinson rating scale, translating to a large and moderate improvement, and 75% improved by 5 points or more. This result is similar to deep brain stimulation (DBS), but the key point here is the safety of the approach,” During says. “This approach is not just symptomatic, but has the potential of being neuroprotective and altering the natural history of the disease. As such it represents a significant advance for Parkinson's disease."
The study was published online today in the journal Lancet Neurology.
Safety of Gene Therapy
Study researcher Andrew Feigin, MD, says the gene therapy is a completely novel approach to treating Parkinson’s disease.
Feigin is an associate professor of neurology and molecular medicine at The Feinstein Institute for Medical Research in Manhasset, N.Y. He has no ties to Neurologix and is not involved with developing the gene therapy.
Feigin tells WebMD that it is not yet clear if the treatment is more effective or is as effective as deep brain stimulation (DBS), which is the most widely used surgical treatment for Parkinson’s disease.
“Even if this proves to have comparable or even near-comparable efficacy to DBS, I would think that it might still have a place in treatment,” he says. “Most importantly, this study shows this kind of therapy can be done safely.”
