Outcome Measures
Primary Outcomes (1)
assess the impact of stimulation of parasympathetic activity by transcutaneous auricular vagus nerve stimulation (taVNS) on quality of life (QoL) relating to digestive symptoms in patients undergoing first-line treatment for ovarian cancer, as compared t
Score of the QoL dimension relating to digestive symptoms according to the EORTC QLQ-OV28 self-questionnaire
At the beginning of Cycle 3 (each cycle is 21 days)".
Secondary Outcomes (7)
The evolution of heart rate variability (HRV) during chemotherapy between the 2 groups of patients
Measured at inclusion and on day 1 of each course before chemotherapy infusion
The safety profile
During chemotherapy (6 cycles, each cycle is 21 days), so up to 5 months after inclusion
The compliance with the use of the device
During chemotherapy (6 cycles, each cycle is 21 days), so up to 5 months after inclusion
- The evolution of markers of inflammation (NLR, CRP, Albumin) during chemotherapy
At inclusion and during cycles 3 and 6 of chemotherapy (each cycle is 21 days)
Quality of life during chemotherapy
At inclusion, at courses 3 and 6 of chemotherapy (each cycle is 21 days)
- +2 more secondary outcomes
Study Arms (2)
Experimental group
EXPERIMENTALtranscutaneous auricular vagus nerve stimulation (taVNS)
Control group
PLACEBO COMPARATORplacebo using the same device that does not deliver electrical stimulation
Interventions
The intervention begins on the first day of chemotherapy and continues daily until 21 days after the end of chemotherapy (6 cycles). The dispositive is used every day at home, twice daily (during 30 minutes)
