tAN per PTSD e OUD nella terapia con buprenorfina
IMBUE RETAIN: neurostimolazione auricolare transcutanea (tAN) per pazienti con disturbo da stress post-traumatico (PTSD) concomitante e disturbo da uso di oppioidi che iniziano la terapia con buprenorfina
The goal of this research study supported by the HEAL Initiative (https://heal.nih.gov) is to investigate the effects transcutaneous auricular neurostimulation (tAN), as delivered through the Sparrow Ascent device, on helping people with co-occurring posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) start and continue buprenorphine treatment. The main questions it aims to answer are:
- Does the tAN help participants with OUD and PTSD remain in buprenorphine therapy for three months after starting use of the device (i.e., randomization to treatment condition)?
- Do participants find the Sparrow Ascent device to be acceptable and use it?
- Do participants find the Sparrow Ascent device to be tolerable and comfortable to use?
- Do participants find the Sparrow Ascent device to be easy to use with their buprenorphine therapy?
- Do participants follow the minimum recommended dose schedule for the Sparrow Ascent device most of the time?
Participants will complete a baseline assessment to make sure that they are eligible to participate in the study. The assessment captures information about demographics, substance use and treatment history, opioid withdrawal symptoms and craving, difficult life experiences and PTSD symptoms, mental health and treatment history, quality of life, and recovery resources. After the assessment is complete and the participant has been inducted on buprenorphine as part of standard care, they are randomized to one of two treatment conditions: active tAN and placebo. Participants are trained on how to use the device and return for 12 weekly research visits to check on recent substance use and craving, PTSD symptoms, and their experience using the device. After 12 weeks of using the device, participants will complete a post-active treatment assessment that is nearly identical to the baseline assessment to see if there have been changes in these areas. Researchers will access the medical record to determine whether there is a current prescription for buprenorphine at three months and six months after randomization.

Descrizione dettagliata
Supported by the HEAL Initiative (https://heal.nih.gov), the overall UG3/UH3 phased project will test transcutaneous auricular neurostimulation (tAN) to the trigeminal and vagus nerves via the Sparrow Ascent device as an adjunct intervention to improve retention in buprenorphine treatment (BUP) for patients with co-occurring opioid use disorder and posttraumatic stress disorder. The specific objectives of the UG3 project are to:
- conduct a pilot randomized, active sham-controlled test of transcutaneous auricular neurostimulation (tAN) with the Sparrow Ascent device to determine its acceptability, tolerability, feasibility, and adherence in patients with OUD and PTSD starting buprenorphine (BUP) therapy;
- submit progress for review regarding study milestones and go/no-go criteria for approval of the UH3 phase; and
- complete FDA pre-submission for FDA input on proposed UH3 protocols to expand Sparrow Ascent's indication for PTSD symptoms.
Approximately twenty adults diagnosed with opioid use disorder and posttraumatic stress disorder initiating buprenorphine treatment will complete a baseline assessment of substance use and mental health diagnostic measures before being randomized into the study. Participants randomized to the active tAN condition will receive therapeutic stimulation to the trigeminal and vagus nerves through the Sparrow Ascent earpiece when they activate their Patient Controller. Participants randomized to the active sham condition will receive only stimulation on the trigeminal nerve at a level that can be felt but is well below any therapeutic effect. All participants will receive identical training for the Sparrow Ascent device and the only difference will be the condition-dependent programming of their Patient Controllers. Participants begin using the Sparrow Ascent device within 28 calendar days of buprenorphine induction. For the next 12 weeks, as they continue through standard buprenorphine treatment, participants will independently administer stimulation at or above a recommended dosage schedule that decreases in frequency every four weeks during the active participation period (i.e., Weeks 1-4, 5-8, 9-12). Device usage logs will be downloaded and assessed at weekly research visits throughout the active participation period to determine device adherence and provide feedback and assistance, if needed. After 12 weeks of device usage, participants return their device and complete a post-assessment that repeats many of the baseline assessments to determine changes from baseline. Buprenorphine treatment retention (primary outcome) at three months and six months (secondary outcome) post-randomization will be extracted from the electronic medical record.

- Unable to provide sufficient contact information (must provide at least two reliable indicators).
- Volunteers who will not undergo induction on BUP within the eligibility window for randomization.
- Volunteers who intend to, or will receive, inpatient substance use disorder (SUD) care at the time of randomization. Volunteers receiving inpatient detoxification care at the time of screening or baseline assessment are eligible if they will no longer be receiving inpatient care when they would be randomized for the study.
- Volunteers actively participating in evidence-based psychotherapy for PTSD (e.g., Prolonged Exposure, Cognitive Processing Therapy, etc.).
- Volunteers who will not have been stable on medications that affect PTSD (i.e., sertraline, paroxetine, venlafaxine, prazosin, or trazodone) for at least four weeks before they could be randomized.
- Volunteer presents current evidence of an uncontrolled and/or clinically significant medical or psychiatric condition that will impact their ability to comply with the study requirements or would make their study participation unsafe. This includes unmedicated bipolar disorder with a manic episode in the past month or unmedicated psychotic disorder.
- Volunteer has a history of epileptic seizure.
- Volunteer has a history of neurological disorder or traumatic brain injury with significant lasting effects (e.g., memory problems, emotional changes, behavioral changes).

Sperimentale: Active tAN
Participants receive active tAN with the Sparrow Ascent device from Spark Biomedical (Dallas, TX). |
The Sparrow Ascent device from Spark Biomedical (Dallas, TX), applies stimulation frequencies of 15 Hz at the cymba concha (vagal innervation) and 100 Hz anterior to the tragus (trigeminal innervation). Both tAN and active sham conditions have square biphasic waveforms with identical pulse widths of 250 µs separated by a 125 µs interval between pulses. Stimulation is applied using a duty cycle of 5-minutes ON and 10 seconds OFF. The stimulation intensities (mA) will be programmed for each individual based on the highest amplitude for each channel that is both comfortable and perceptible. Patients using the device may alter the intensity of stimulation at these sites using the Patient Controller to achieve the desired effect.

|
Comparatore fittizio: Active Sham
Participants receive the active sham version of the Sparrow Ascent device that limits stimulation to trigeminal innervation only and at a charge that is approximately 1000x lower than the active tAN condition. |
The Sparrow Ascent Active Sham is a modified version of the Sparrow Ascent tAN System that has been designed to provide sub-therapeutic stimulation to the trigeminal nerve only and no stimulation to the vagus nerve. The trigeminal nerve will receive 1 Hz stimulation at the temporomandibular region at an amplitude that is comfortable and perceptual. The pulse duration will be set to a value that does not exceed 250 μs in a square biphasic waveform. The patient controller device for the active sham will give the appearance that stimulation is being applied at both vagal and trigeminal electrode sites. |

Descrizione del piano IPD
We will create a completely de-identified dataset to prevent linkages to individual research participants. This includes removal of all Protected Health Information (PHI) and indirect identifiers that are not listed as PHI but could lead to "deductive disclosure" such as site numbers.
Proprietary protocols regarding the Sparrow device are the intellectual property of Spark Biomedical, Inc. and will not be shared.
This dataset, with related study materials (e.g., study protocol, define file, data dictionary, etc.), will be made available to investigators with a data-sharing agreement. The data sharing agreement will require commitment to: 1) not re-disclose the data; 2) secure the data; 3) use the data for research purposes only; 4) make no attempt to identify individual participants; 5) destroy the data once the planned research activities have been completed; and 6) follow all relevant National Institutes of Health (NIH) policies.
Periodo di condivisione IPD
The shared data will be made available to other users by no later than the main findings are accepted for publication or 1-year post-study completion, whichever comes first. Published studies will have their own subcollections in the master Open Science Framework (OSF) project collection with the exact dataset used for the manuscript. These subcollections will have DOIs to aid in findability. We will include the DOI in relevant publications. The de-identified data will be retained indefinitely.
Criteri di accesso alla condivisione IPD
Data will be findable for the research community through the OSF collection that will be established when this application is funded. We will reference the shared data in OSF in peer-reviewed publications and relevant webpages. For each publication, an OSF subcollection will be created within the master OSF project. Each subcollection will have a digital object identifier (DOI) associated with it. This data DOI will be referenced in the publication and associated presentations to allow the research community easy access to the exact data used in the publication. When these links are followed, researchers will view the instructions and requirements for establishing a data use agreement for access.
Access to the data will be controlled and require a signed data use agreement. PI Sprunger will be responsible for administering these agreements.
