DBS treatment may slow the progression of Parkinson’s tremor in early-stage patients

Deep brain stimulation (DBS) may slow the progression of tremor for early-stage Parkinson’s disease patients, according to a Vanderbilt University Medical Center study released in the June 29 online issue of Neurology, the medical journal of the American Academy of Neurology.

The study is the first evidence of a treatment that slows the progression of one of the cardinal features of Parkinson’s, but a larger-scale clinical trial across multiple investigational centers is needed to confirm the finding.

“The finding concerning tremor progression is truly exceptional,” said senior author David Charles, MD, professor and vice-chairman of Neurology. “It suggests that DBS applied in early-stage Parkinson’s disease may slow the progression of tremor, which is remarkable because there are no treatments for Parkinson’s that have been proven to slow the progression of any element of the disease.”

Patients in the Vanderbilt study were randomized to receive DBS plus drug therapy or drug therapy alone; the drug therapy alone group was seven times more likely to develop new rest tremor after two years in comparison to the DBS plus drug therapy group.

The trial, which began in 2006, was controversial because it recruited patients with early-stage Parkinson’s disease for DBS brain surgery. At that time, DBS was approved for only advanced-stage Parkinson’s disease when symptoms were no longer adequately controlled by medication.

“Since this was the first early DBS trial, it was unknown whether there were individual motor symptoms very early in Parkinson’s disease that may be more potently improved by DBS,” said lead author Mallory Hacker, Ph.D., research assistant professor of Neurology.

The post hoc analysis showed that 86 percent of the drug therapy patients developed rest tremor in previously unaffected limbs over the course of the two-year period, while that occurred in only 46 percent of patients who had received DBS therapy in addition to drug therapy. Four of the DBS patients had rest tremor improvement and rest tremor completely disappeared from all affected limbs for one DBS patient.

The FDA has approved Vanderbilt to lead a large-scale, Phase III multicenter study that will enroll 280 people with very early-stage Parkinson’s disease, beginning in 2019, and 17 other U.S. medical centers have joined the DBS in Early Stage Parkinson’s Disease Study Group to participate.

“The field of DBS therapy for Parkinson’s disease is moving toward earlier stages of treatment, therefore, we must conduct the pivotal trial to ensure patient safety and provide the Parkinson’s community with the best possible medical evidence to guide treatment,” Charles said.
