Not Applicable

Recruiting

• Conditions: Opioid Withdrawal (Disorder); Opioid Use Disorder

• Registration Number: NCT07079215
• Lead Sponsor: Nu Eyne Co., Ltd.

Brief Summary

This study aims to evaluate the safety and efficacy of a physical device for medical use (ADTPM 1) applied to opioid withdrawal symptoms.

Detailed Description

This study is a single-center, double-blind, randomized, sham-controlled, parallel-design exploratory clinical trial to evaluate the safety and efficacy of a physical device for medical use (ADTPM 1) in adults with opioid withdrawal symptoms. Eligible participants will be randomized to receive either active stimulation or sham stimulation applied to the auricular region daily for 60 minutes over a 4-week period. The primary objective is to assess the incidence of treatment-emergent adverse events. Secondary objectives include evaluating changes in opioid withdrawal severity, craving, pain, heart rate, depressive symptoms, anxiety, insomnia, somatic symptoms, and DSM-5 criteria for opioid use disorder over time.

Inclusion Criteria

1. Participants aged 19 to 80 years
2. Participants currently dependent on opioids, whether prescribed or non-prescribed
3. Participants who meet the criteria for opioid use disorder (OUD) according to DSM-5
4. Participants with a Clinical Opiate Withdrawal Scale (COWS) score of 5 or higher
5. Participants with a Numeric Rating Scale (NRS) pain score of less than 6
6. Participants who have voluntarily decided to participate in the study and have provided written informed consent
7. Participants who are willing to comply with the study protocol

Exclusion Criteria

1. Participants with any current uncontrolled or clinically significant medical condition

2. Participants with a history of seizures or epilepsy

3. Participants with a history of neurological disorders or traumatic brain injury

4. Participants who have used long-acting opioids, such as methadone or buprenorphine, continuously for more than 5 days prior to screening

5. Participants who have used methadone within 30 days prior to screening

6. Participants who have used buprenorphine within 7 days prior to screening

7. Participants with physiological dependence on alcohol or drugs other than opioids, tobacco, or marijuana

8. Participants diagnosed with a major psychiatric disorder (psychosis, schizophrenia, or bipolar disorder)

9. Participants who are currently hospitalized due to a recent suicide attempt or who are persistently expressing suicidal intent

10. Participants with implanted devices such as a pacemaker, cochlear implant, or neurostimulator.

11. Participants with abnormal ear anatomy or ear infections

12. Participants diagnosed with renal or hepatic failure

13. Participants who are currently undergoing chemotherapy (Exception: Participation may be allowed if the investigator determines that participation poses no medical safety concerns for the participant)

14. Participants who are currently engaged in high-risk occupations (e.g., transportation workers, crane operators, heavy machinery operators, individuals working with sharp objects, or those requiring a high level of cognitive functioning)

15. Participants with implanted metal or electronic devices in the head or neck area, including deep brain stimulators or pacemakers, as specified in the product precautions and contraindications (dental implants are exempt)

16. Participants with cognitive impairment due to neurodevelopmental disorders (e.g., intellectual disability, developmental disorders, autism spectrum disorder) or neurodegenerative disorders (e.g., Alzheimer's disease, vascular dementia) that would make it difficult to undergo treatment with the investigational medical device

17. Participants who are pregnant or breastfeeding

18. Female participants of childbearing potential who do not agree to abstain from sexual intercourse or to use medically accepted contraception* during the study period.

    *Medically accepted methods of contraception include: condoms, consistent oral contraceptive use (≥3 months use), injectables or implantable contraceptives, or intrauterine devices (IUDs).

19. Participants who are currently participating in another clinical trial or who have participated in another clinical trial within 30 days prior to screening

20. Participants who, in the opinion of the investigator, are deemed inappropriate for participation due to ethical concerns or potential impacts on study outcomes

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Incidence of Treatment-Emergent Adverse Events (TEAEs)	[Time Frame: Baseline to Week 4]	The primary outcome is the incidence and severity of treatment-emergent adverse events (TEAEs) occurring from the first device application through the end of the 4-week treatment period. TEAEs include, but are not limited to, mild adverse events such as dizziness, somnolence, skin irritation, and headache. Safety will be assessed by monitoring vital signs, conducting physical examinations, and recording adverse events throughout the study period.

Secondary Outcome Measures

Name	Time	Method
Change in Clinical Opiate Withdrawal Scale (COWS) Scores	[Time Frame: Baseline, 1 Hour, Day 2, Week 1, Week 2, Week 3, Week 4]	Change from baseline in COWS scores to assess the severity of opioid withdrawal symptoms over time. Higher scores indicate more severe withdrawal symptoms.
Change in Subjective Opiate Withdrawal Scale (SOWS) Scores	[Time Frame: Baseline, 1 Hour, Day 2, Week 1, Week 2, Week 3, Week 4]	Change from baseline in SOWS scores to evaluate patient-reported withdrawal symptoms. Higher scores indicate more severe withdrawal symptoms.
Change in Opioid Craving Visual Analogue Scale (OC-VAS)	[Time Frame: Baseline, 1 Hour, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in opioid craving levels measured by a visual analogue scale. Higher scores indicate more severe craving.
Change in Heart Rate	[Time Frame: Baseline, 1 Hour, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in resting heart rate from baseline to assess physiological responses related to withdrawal. Higher heart rate may reflect increased autonomic arousal associated with withdrawal.
Change in Numerical Rating Scale (NRS)	[Time Frame: Baseline, 1 Hour, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in self-reported pain severity measured by the NRS. Higher scores indicate greater pain intensity.
Change in Montgomery-Åsberg Depression Rating Scale (MADRS) Scores	[Time Frame: Baseline, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in depressive symptom severity from baseline. Higher scores indicate more severe depressive symptoms.
Change in Generalized Anxiety Disorder-7 (GAD-7) Scores	[Time Frame: Baseline, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in anxiety symptom severity from baseline. Higher scores indicate more severe anxiety symptoms.
Change in Insomnia Severity Index-Korean (ISI-K) Scores	[Time Frame: Baseline, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in insomnia symptoms assessed by ISI-K. Higher scores indicate more severe insomnia symptoms.
Change in Patient Health Questionnaire-15 (PHQ-15) Scores	[Time Frame: Baseline, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in somatic symptom severity over the treatment period. Higher scores indicate more severe somatic symptoms.
Change in DSM-5 Criteria for Opioid Use Disorder	[Time Frame: Baseline, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in diagnostic status of opioid use disorder as defined by DSM-5. Meeting more criteria indicates greater disorder severity
Change in Opioid Craving Scale (OCS-3) Scores	[Time Frame: Baseline, Day 2, Week 1, Week 2, Week 3, Week 4]	Change in opioid craving symptoms measured by OCS-3. Higher scores indicate more severe craving.
