Official title
Transcutaneous Auricular Vagal Nerve Stimulation for Treatment of Radiation Necrosis
Overview
This is a multi-center, randomized, blinded trial evaluating the effect of transcutaneous auricular vagal nerve stimulator (taVNS) on radiation necrosis-related cerebral edema. In this study, consenting and eligible patients will be assigned to one of two arms: treatment (Arm 1) or sham (Arm 2). Patients in both arms will have imaging performed and tissue and blood collected for assessment of changes in area of contrast enhancement and cerebral edema, inflammatory markers, and markers of blood-brain barrier permeability.
Interventions
- Device Transcutaneous auricular vagal nerve stimulation (taVNS)
Transcutaneous auricular vagal nerve stimulation (taVNS) stimulation twice daily for 12 to 14 days prior to planned LITT ablation via TENS (transcutaneous electrical nerve stimulation) unit connected to an earpiece that fits into the concha of the ear. - Device Sham
TENS (transcutaneous electrical nerve stimulation) unit connected to an earpiece that fits into the concha of the ear, with no stimulation twice daily for 12 to 14 days prior to planned LITT ablation.
Primary outcome measures
- Assess changes in the serum inflammatory marker Tumor Necrosis Factor (TNF)-alpha [Time frame: Baseline, 1 week, and 2 weeks following intervention]
Secondary outcome measures (12)
- Assess changes in serum inflammatory marker Interleukin 12 (IL-12) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker granulocyte-macrophage colony-stimulating factor (GMCSF) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker Interferon gamma (IFN gamma) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin 1 beta (IL-1b) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin-10 (IL-10) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin 13 (IL-13) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin (IL-2) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory markers interleukin 17 (IL-17A) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin 4 (IL-4) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin 5 (IL-5) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin 6 (IL-6) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
- Assess changes in serum inflammatory marker interleukin 8 (IL-8) [Time frame: Baseline, 1 week, and 2 weeks following intervention]
Eligibility criteria
Inclusion criteria
- History of glioma or metastatic brain lesion previously treated with whole brain radiation, stereotactic radiation surgery, or fractionated radiation therapy
- Magnetic resonance imaging (MRI) findings consistent with possible radiation necrosis within 6 weeks prior to enrollment.
- Candidate for tissue biopsy and Laser Interstitial Thermal Therapy (LITT) ablation of the lesion
- At least 18 years of age
- If on corticosteroids, able to discontinue at least 5 days prior to start of transcutaneous auricular vagus nerve stimulation (taVNS) (Arm 1) or sham treatment (Arm 2). A stable physiologic dose of corticosteroids, if used as hormone replacement therapy, may be allowed upon discussion with the investigator. 6. Ability to understand and willingness to sign an institutional review board (IRB) approved written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants.
Exclusion criteria
