Using vagus nerve stimulation to improve quality of life in ovarian cancer treatment

Official title: Benefit of Transcutaneous Auricular Vagus Nerve Stimulation in Improving Quality of Life in First Line Treatment of Ovarian Cancer: the ESTANVO Randomized Trial

Run by Centre Francois Baclesse · NCT06817161 · Data updated 2026-11-12

This study is testing if a new device that stimulates the vagus nerve can help improve the quality of life for women undergoing chemotherapy for ovarian cancer by reducing digestive problems.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically confirmed epithelial ovarian carcinoma who are starting first-line chemotherapy.

Probably not a fit

Patients with active implantable medical devices or severe cardiovascular diseases may not benefit from this study.

What this trial studies

This clinical trial investigates the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on the quality of life of patients undergoing first-line chemotherapy for ovarian cancer. Participants will be randomly assigned to receive either active taVNS or a placebo device that does not deliver electrical stimulation. The primary focus is on alleviating digestive symptoms associated with chemotherapy. The study aims to determine if stimulating the parasympathetic nervous system can enhance overall well-being during treatment.

Why it matters

Potential benefit: If successful, this approach could significantly improve the quality of life for patients undergoing treatment for ovarian cancer.

How similar studies have gone: While the use of vagus nerve stimulation is gaining interest, this specific application in ovarian cancer treatment is relatively novel and has not been extensively tested in prior studies.
