DBSpostVNS Trial Summary

This trial is comparing DBS to VNS in children with failed VNS who have drug-resistant epilepsy.

Who is the study for?
This trial is for children aged 8 to under 18 with drug-resistant epilepsy who have not seen improvement after using two anti-epileptic medications and vagal nerve stimulation (VNS). Participants need a re-diagnosis by a neurologist, must be able to follow the study's procedures for a year, and have consent from parents or guardians. Those unable to return for follow-ups or with substance abuse issues, or MRI contraindications cannot join.Check my eligibility
What is being tested?
The study compares deep brain stimulation (DBS) effectiveness against continued optimization of VNS in children whose seizures didn't improve with VNS. It's a non-blinded trial involving 50 patients across multiple centers, assessing which treatment better controls epilepsy symptoms.See study design
What are the potential side effects?
While specific side effects are not listed here, DBS can generally cause headache, seizure, confusion, difficulty concentrating, stroke-like symptoms and hardware complications like infection at the implantation site.

DBSpostVNS Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: DBS TreatmentExperimental Treatment1 Intervention
Patients in the treatment arm will receive DBS of bilateral centromedian nucleus (2 electrodes per patient). DBS is a standard of care treatment option for drug-resistant epilepsy patients who have previously failed VNS at 12 months or more after instigation and optimization of therapy.
Group II: Continued VNS (control)Active Control1 Intervention
For the control arm, the patients will be monitored for one year with the same standard assessments used for the measurement of seizure frequency and severity. No changes will be made to these patients' treatment plan. These patients will be placed on a wait list for CM-DBS treatment of seizures if that is the desire of the patient and/or their family. After the 12 months of observation, these patients can choose to undergo DBS surgery.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Does this research still have the capacity to accept additional participants?

"Affirmative. The records hosted on clinicaltrials.gov confirm that this medical trial, initially posted on November 25th 2019, is actively searching for volunteers. Approximately 50 people must be recruited from a single centre."

Answered by AI

How many individuals are eligible to join this clinical exploration?

"Affirmative. According to data on clinicaltrials.gov, this trial is actively seeking participants and was initially posted on November 25th 2019 with the most recent update being May 11th 2022. A total of 50 patients are needed from 1 medical centre for enrolment in this study."

Answered by AI

Does this trial cater to those aged 65 and over?

"To qualify for this trial, applicants must be between 8 and 18 years old. 104 clinical trials are currently conducted for the under-18 demographic, while an additional 165 focus on those above 65 yrs of age."

Answered by AI

Is it feasible for me to join the research endeavor?

"This clinical trial is searching for 50 children between the ages of 8 and 18 who have been diagnosed with drug-resistant epilepsy. To qualify, they must be male or female and have unsuccessfully tried two anti-epileptic medications (Kwan et al. 20093). Additionally, their legal guardians/caregivers need to provide consent, they must comply with all testing protocols & follow-ups over a 12 month period post study completion, and finally vagal nerve stimulation should not have yielded improved results at least 1 year following its initiation in order to fulfill eligibility criteria."
