About this study
Official title: Efficacy and Safety of Dual-target Deep Brain Stimulation for Treatment-resistant Alcohol Use Disorder: a Multi-center, Single Arm, Prospective, Open-label, Extendable Study
This is a multi-center, single arm, prospective, open-label, extendable study for the efficacy and safety of dual-target deep brain stimulation for treatment-resistant alcohol use disorder.
Read the detailed description
Total of 12 subjects from two centers ( Shanghai Mental Health Center and The Second Xiangya Hospital of Central South University ) who fit inclusion and exclusion criteria are recruited to undergo neurosurgical implantation of dual-target Deep Brain Stimulation (DBS) in bilateral nucleus accumbens (NAcc) and anterior limb of internal capsule (ALIC) on a certain date, the DBS system will be turned on for stimulation and parameters adjusted 10-14 days after implantation, treatment purposes are evaluated after DBS system has been turned on for 9-32 weeks. Primary efficacy is evaluated by major alcohol consumption rate, uncontrolled alcohol consumption days, maximum consecutive alcohol suspension days. Safety is evaluated by adverse events (AE) and device related AE, serious adverse events (SAE) and device related SAE, device deficiencies (DD) and device malfunction, physical examination and vital signs, laboratory examination, ECG, imageological examination, scale evaluation and early drop out ratio due to AE.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
dual-target deep brain stimulationDevice
DBS electrodes will be implanted into the ALIC and the NAcc, electric stimulation of those areas are used to treat alcohol use disorder and to evaluate the efficacy and safety of DBS system.
| Study group | Role | What they receive |
|---|---|---|
| dual-target deep brain stimulation | Experimental | This is a single arm, prospective, open label clinical study, participants who fit inclusion/exclusion standards, completed physical anti-addiction treatments and surgical implantation standard will start DBS system stimulation and adjust parameters after 10-14 days of implantation. Then after stimulation for 9-32 weeks, they will be evaluated for treatment efficacies. This study is extendable, with agreements from participants, long term efficacy and safety follow-up study will be performed after 32 weeks ± 7 days of following, once every 2-3 months. Receives: Device: dual-target deep brain stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Major alcohol use rate
Calculation formula: 'major alcohol use' times / 56 (total observation times) * 100%
Measured: 24 weeks
Cumulated uncontrolled alcohol use days
- Definition: more than 3 times consecutive alcohol use (random draw) ≥ 5 standard cups
- One time uncontrolled alcohol use days: e.g. 3 times consecutive follow-up results ≥ 5 standard cups, fourth time < 5 standard cups, then uncontrolled alcohol use days is 3 * 3 = 9 days
- Cumulated uncontrolled alcohol use days: Total days of all uncontrolled alcohol use days throughout 24 weeks
Measured: 24 weeks
Maximum consecutive alcohol suspension days
- Marked as maximum days of 'Constant alcohol suspension' b) Note: i. Major alcohol use standard: Blow test positive and reported ≥ 5 standard cups daily over the past 3 days. 1 standard cup = 10g of pure alcohol. ii. Minor alcohol use standard: No matter blow test is positive or not, alcohol use is reported over past 3 days but less than 5 standard cups. iii. Constant alcohol suspension standard: Blow test negative and no alcohol use reported over past 3 days.
Measured: 24 weeks
Secondary outcomes (7)
Alcohol use volume
9-32 weeks after stimulation, change in monthly average alcohol use volume compared to baseline. (Record in every follow-up according to participants. Record alcohol type, amount and experience when drinking throughout 9-32 weeks after stimulation. Increased value implies worse result and reduce of alcohol use volume indicates improvement.
Measured: 24 weeks
Cumulated alcohol suspension days
total value of 'Constant alcohol suspension' days after 9-32 weeks of stimulation.
Measured: 24 weeks
Subjective alcohol urge
Change in alcohol urge Visual Analogue Score compared to baseline. ( 0 is no urge, 10 is extreme urge)
Measured: At 12, 20 and 32 weeks of stimulation
Alcohol abstinence
Change in CIWA-Ar score compared to baseline.
Measured: At 12, 20 and 32 weeks of stimulation
Sleep condition
Pittsburgh Sleep Quality Index score compared to baseline.
Measured: At 12, 20 and 32 weeks of stimulation
Emotion condition
Hamilton Anxiety Scale-17 and Hamilton Depression Scale score compared to baseline.
Measured: At 12, 20 and 32 weeks of stimulation
Social functions
SDSS score compared to baseline.
Measured: At 12, 20 and 32 weeks of stimulation
