Study summary

This purpose of this study is to evaluate whether transcutaneous auricular vagus nerve stimulation (taVNS) improves chemotherapy-induced peripheral neuropathy (CIPN) symptoms by assessing changes in daily symptom trajectories following treatment initiation. The study will also examine potential mechanisms of action through longitudinal assessment of inflammatory biomarkers, corticospinal excitability, and autonomic nervous system function.

Inclusion criteria

  1. Age 18-80 years
  2. Prior exposure to platinum, taxane, or vinca alkaloid chemotherapy
  3. Glove/stocking dysesthesias ≥3 months that began after neurotoxic chemotherapy
  4. Worst CIPN-related symptom ≥4/10 over the last week

Exclusion criteria

Exclusion Criteria:

  1. Unstable cardiac disease/Known arrhythmias
  2. Head or neck cancer or
  3. Recent ear trauma or active dermatologic disease at the stimulation site
  4. \<2 months since completion of cancer treatment or surgery (i.e, tumor resection, radiation therapy, and/or taxane/platinum/vinca alkaloid chemotherapy treatments. Maintenance therapies, including hormonal therapy or Poly (ADP-ribose) Polymerase (PARP) inhibitors, are allowed and not part of exclusion criteria. Patients may have pending reconstructive surgeries planned as long as it is planned outside of the study participation window.)

Study arms

  • Experimental
    Auricular Vagus Nerve (AVNS) Group

    Participants in this group will receive a 2-week course of daily self-applied transcutaneous auricular vagus nerve stimulation (taVNS). Participants will use a portable taVNS device at home once daily for 14 consecutive days, applying stimulation to the auricular vagus nerve according to standardized instructions provided by the study team. Each stimulation session will last approximately 60 minutes.

    Device: Sparrow Link (taVNS)

Interventions

  • DeviceSparrow Link (taVNS)

    Participants will self-administer transcutaneous auricular vagus nerve stimulation (taVNS) using the Sparrow Link portable stimulator and flexible ear electrodes for 1 hour daily for 14 days (total stimulation time: 14 hours).The treatment stimulation intensity can be increased up to 5mA, but this will be adjusted for each participant to ensure it is below the pain threshold.

What researchers measure

Primary outcomes

  1. Change in Daily Chemotherapy-Induced Peripheral Neuropathy Symptom Severity Measured by Numeric Rating Scale (NRS)

    Participants will complete a daily electronic diary rating the severity of their most bothersome chemotherapy-induced peripheral neuropathy (CIPN) symptom (pain, numbness/tingling, burning, pressing/squeezing, or electric shocks) during the previous 24 hours using an 11-point Numeric Rating Scale (NRS), where 0 = no symptoms and 10 = worst imaginable symptoms. The primary analysis evaluates symptom trajectories using daily observations collected during the baseline and treatment periods.

    Time frame: Baseline (Days -14 to 0), Treatment period (Day 1-14)

Secondary outcomes

  1. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Chemotherapy-Induced Peripheral Neuropathy 20 (EORTC QLQ-CIPN20)

    The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20 (EORTC QLQ-CIPN20) is a validated 20-item questionnaire that assesses sensory, motor, and autonomic neuropathy symptoms. Responses are transformed to 0-100 subscale scores, with higher scores indicating greater symptom severity.

    Time frame: Baseline (Day 0), Day 15, and Day 45 follow-up

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jan 2027; primary completion for Jun 2029, 29 months later.

Of 246 non-industry interventional studies with no phase under Neuralgia, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 41. This study's planned 29 months is above that.

Counting every sponsor, half of 264 studies reached it within 24 months; a quarter within 10 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
