NCT06443242

Brief Summary

The goal of this randomized controlled trial is to assess the efficacy and safety of low-dose laser acupuncture (LLA) in alleviating insomnia symptoms among patients suffering from major depressive disorder. The study seeks to answer the following questions:

  1. 1.How effective is LLA in alleviating insomnia symptoms as compare with SLA and control subjects among patients with major depressive disorder across pre-treatment, mid-treatment and post-treatment assessment?
  2. 2.How effective is LLA in alleviating depression symptoms as compare with SLA and control subjects among patients with major depressive disorder across pre-treatment, post-treatment and follow-up assessment?
  3. 3.What role do CORT and 5-HT play in the co-occurrence and progression of insomnia and major depressive disorder, and how does LLA act on these mechanisms to provide relief?
  4. 4.How does the safety and acceptability of LLA compare to traditional acupuncture in terms of eliminating discomfort and potential side effects? Researchers will compare the effects of LLA with sham laser acupuncture (SLA) and standard medication treatments to evaluate its efficacy and safety.

Outcome Measures

Primary Outcomes (1)

  • Change in sleep quality from pre-treatment assessed by the Pittsburgh Sleep Quality Index (PSQI) score at immediately post-treatment and 12 weeks post-treatment

    This outcome measure evaluates the change in sleep quality in patients with major depressive disorder (MDD) and insomnia treated with Low-Dose Laser Acupuncture (LLA). The Pittsburgh Sleep Quality Index (PSQI) is used, with scores ranging from 0 to 21, where higher scores indicate poorer sleep quality.

    Pre-treatment, immediately post-treatment and 12 weeks post-treatment.

Secondary Outcomes (8)

  • Changes in severity of depressive symptoms from pre-treatment assessed by Hamilton Depression Rating Scale (HAMD) score at immediately post-treatment and 12 weeks post-treatment

    Pre-treatment, immediately post-treatment and 12 weeks post-treatment.

  • Changes in severity of insomnia from pre-treatment measure by Insomnia Severity Index (ISI) score at immediately post-treatment and 12 weeks post-treatment

    Pre-treatment, immediately post-treatment and 12 weeks post-treatment

  • Changes in serum corticosterone levels from pre-treatment measure by Immunoassays at immediately post-treatment and 12 weeks post-treatment

    Pre-treatment, immediately post-treatment and 12 weeks post-treatment.

  • Changes in serum 5-Hydroxytryptamine (5-HT) levels from pre-treatment measure with Enzyme-Linked Immunosorbent Assay at immediately post-treatment and 12 weeks post-treatment

    Pre-treatment, immediately post-treatment and 12 weeks post-treatment.

  • Changes in the incidence of treatment-emergent adverse events from pre-treatment assess as dropout rates at immediately post-treatment and 12 weeks post-treatment

    Throughout the study duration (Pre-treatment through 12 weeks post-intervention)

  • +3 more secondary outcomes

Study Arms (3)

Low-Dose Laser Acupuncture (LLA) Group

EXPERIMENTAL

In the Low-Dose Laser Acupuncture (LLA) group, participants receive treatments using the xS-998D06 semiconductor laser acupoint therapeutic device from Nanjing Xiaosong Medical Instruments. This device operates at a wavelength of 780 nm and an output power of 5 mW. Each 20-minute session involves securing the device's probe to specific acupoints (Baihui, Yintang, Anmian, Shenmen, Neiguan, Sanyinjiao, and Taichong) using medical tape. Treatments occur daily for 5 consecutive days each week, with a two-day break, over a 6-week period. All participants, regardless of group assignment, will maintain their regular antidepressant regimen (patients with only one type of antidepressant, such as selective serotonin reuptake inhibitor \[SSRI\] or serotonin noradrenaline reuptake inhibitor \[SNRI\] or mirtazapine).

Device: Low-Dose Laser Acupuncture (LLA)

Sham Laser Acupuncture (SLA) Group

SHAM COMPARATOR

Participants in the Sham Laser Acupuncture (SLA) group undergo a sham treatment involving the same procedure and acupoint targeting as the LLA group. The difference lies in the instrument probe being fixed to the acupoint but emitting a dummy laser, simulating the acupuncture experience without actual laser emission. All participants, regardless of group assignment, will maintain their regular antidepressant regimen (patients with only one type of antidepressant, such as selective serotonin reuptake inhibitor \[SSRI\] or serotonin noradrenaline reuptake inhibitor \[SNRI\] or mirtazapine).

Device: Sham Laser Acupuncture (SLA)

Control Group

NO INTERVENTION

The control group, which serves as a non-intervention comparison, will continue their standard treatment regimen (patients with only one type of antidepressant, such as selective serotonin reuptake inhibitor \[SSRI\] or serotonin noradrenaline reuptake inhibitor \[SNRI\] or mirtazapine).

Interventions

The intervention utilizes the xS-998D06 semiconductor laser acupoint therapeutic device specifically designed for targeted acupoint therapy. This device is critical in delivering precise low-dose laser therapy at a controlled wavelength and power. The laser treatment is directed towards enhancing neurological function and potentially alleviating symptoms of insomnia and depression by stimulating specific acupoints associated with mental health and sleep.

Low-Dose Laser Acupuncture (LLA) Group

Sham laser acupuncture serves as a control to assess the placebo effect of the laser treatment. It involves the same procedure as LLA but uses a non-emitting laser probe. This intervention is designed to mimic the LLA setup without delivering actual laser therapy, allowing for an evaluation of the psychological and physiological effects of the placebo compared to the active laser treatment.
