Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot study will assess the usefulness and potential effectiveness of using transcutaneous auricular vagus nerve stimulation (tVNS) for treating insomnia in adult survivors of childhood acute lymphoblastic leukemia (ALL). Participants will be randomized to receive either active (verum) or inactive (sham) nightly stimulation using a non-invasive earbud device over two time periods: 2 weeks and 8 weeks. The study will assess adherence to the intervention and estimate its effects on sleep quality, stress, and neurocognitive function.

Primary Objective:

Aim 1: To determine a) short-term and b) long-term feasibility of tVNS in terms of participation in ALL Survivors with moderate to severe insomnia.

Aim 2: To estimate the effect size of tVNS on sleep quality, stress, and neurocognitive outcomes in ALL survivors with insomnia.

Exploratory Objectives

Aim 1: To investigate the onset of tVNS effect via actigraphy measures over the intervention epoch.

Aim 2: To estimate the effect size of genetic variants on sleep quality within verum tVNS.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately 40 adult survivors of childhood ALL enrolled in the SJLIFE cohort will be recruited. Eligible participants must have moderate to severe insomnia (ISI ≥8). The intervention involves nightly use of a tVNS device for 20 minutes before sleep. Participants will be randomized to receive either active or sham stimulation. Feasibility will be assessed based on adherence rates, and efficacy will be estimated using subjective (PSQI, ISI) and objective (actigraphy, CNS Vital Signs) measures. Exploratory analyses will examine the onset of tVNS effects and the influence of genetic variants (BDNF rs6265, COMT rs4680) on treatment response.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

A blinded, randomized sham/placebo-controlled pilot study with self-administered tVNS.

While "Device Feasibility" generally has fewer than 10 participants, the aim is to ensure safety in a novel device population. While this does not fit into "Supportive Care," it also requires more participants for considerations:

* Using a blinded 1:1 sham:verum study design with a control arm to ensure device feasibility is not affected by perceived stimulation. It is important to consider the inherent experience of tVNS.
* As this is a novel population for the device and treatment, the study aims to ensure an adequate sample size to obtain effect size estimates to inform power analyses on future trials will be achieved.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Verum tVNS (Active Treatment)

Participants randomized to receive active transcutaneous auricular vagus nerve stimulation (tVNS) using the Soterix device. Stimulation is delivered nightly for 20 minutes at 80% of the participant's discomfort threshold.

Group Type EXPERIMENTAL

Soterix tVNS device

Intervention Type DEVICE

Active transcutaneous auricular vagus nerve stimulation (tVNS) using the Soterix device.

Stimulation is delivered nightly for 20 minutes at 80% of the participant's discomfort threshold.

Sleep Quality

Intervention Type BEHAVIORAL

Receive Pittsburgh Sleep Quality Index (PSQI); Insomnia Severity Index (ISI); Sleep diaries; Actigraphy via Fitbit Charge 5

Neurocognitive and mental health outcomes

Intervention Type BEHAVIORAL

Measured using CNS Vital Signs and DASS-21.

Sham tVNS (Placebo Comparator)

Participants randomized to receive sham stimulation using the same Soterix device, but with no active electrical stimulation. The procedure mimics the verum condition in duration and setup.

Group Type SHAM_COMPARATOR

Soterix tVNS device (sham programmed)

Intervention Type DEVICE

The sham stimulation used the Soterix device, but without active electrical stimulation. The procedure mimics the verum condition in duration and setup. Inactive stimulation is delivered nightly for 20 minutes at 80% of the participant's discomfort threshold.

Sleep Quality

Intervention Type BEHAVIORAL

Receive Pittsburgh Sleep Quality Index (PSQI); Insomnia Severity Index (ISI); Sleep diaries; Actigraphy via Fitbit Charge 5

Neurocognitive and mental health outcomes

Intervention Type BEHAVIORAL

Measured using CNS Vital Signs and DASS-21.
