About this study

Official title: Compound Ciwujia Granules in the Treatment of Insomnia: a Multi-center, Double-blind, Double-dummy, Randomized Controlled Trial

The goal of this multicenter, double-blind, double-dummy, randomized controlled trial was to examine the efficacy and safety of Compound Ciwujia Granules in the treatment of chronic insomnia. A total of 1200 participants with chronic insomnia were randomly assigned to receive one of the three treatment for 4 consecutive weeks: Compound Ciwujia Granules + placebo of estazolam, estazolam + placebo of estazolam + placebo of Compound Ciwujia Granules, or Compound Ciwujia Granules + estazolam + placebo of estazolam. Outcomes were assessed at 2 weeks, 4 weeks, 8 weeks, and 12 weeks. The main questions it aims to answer are:

  1. Are there any significant differences between groups regarding changes in Pittsburgh Sleep Quality Index (PSQI) score, Insomnia Severity Index (ISI) score, subjective sleep latency, sedative and hypnotics use, improvement in sleep maintenance, Hamilton Depression Scale (HAMD-17) score, Hamilton Anxiety Scale (HAMA-14) score, Flinders Fatigue Scale (FFS) score, and constitution classification/insomnia pattern score of traditional Chinese medicine after 4 weeks' treatment, and follow-up at 8 weeks and 12 weeks.
  2. Is the Compound Ciwujia Granules a safe method for chronic insomnia treatment in adults?
Read the detailed description

The investigators aimed to examine the efficacy and safety of Compound Ciwujia Granules in the treatment of chronic insomnia in a multicenter, double-blind, double-dummy, randomized controlled clinical trial. Eligible participants were adults aged 40-75 years who had insomnia disorder (according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition [DSM5]) or self-reported history of disturbed sleep, diagnosis of "deficiency of the heart and the spleen pattern" or "Qi deficiency of the heart and gallbladder pattern" according to the guidelines for Integrated Traditional Chinese and Western Medicine Treatment of Insomnia Disorders 2023, baseline Pittsburgh Sleep Quality Index (PSQI) score ≥ 8. The exclusion criteria were (1) self-reported allergy symptoms to any of the ingredients; (2) serious physical sickness; (3) a history of suicidal ideation or attempt, acute or chronic psychiatric condition not controlled by therapy; (4) baseline HAMD-17 score ≥17 or HAMA-14 score ≥14;(5) pregnant women; (6) history of drugs or alcohol abuse/dependence; (7) presence of other sleep disorders including sleep apnoea, restless legs syndrome; (8) night, morning or rotating shift work; (9) participation in concurrent clinical trials. The primary outcome was the change in Pittsburgh Sleep Quality Index (PSQI) score after 4 weeks' treatment. The secondary outcomes were changes in Insomnia Severity Index (ISI) score, subjective sleep latency, sedative and hypnotics use, improvement in sleep maintenance, Hamilton Depression Scale (HAMD-17) score, Hamilton Anxiety Scale (HAMA-14) score, Flinders Fatigue Scale (FFS) score, and constitution classification/insomnia pattern score of traditional Chinese medicine, as well as the occurrence of adverse events after 4 weeks' treatment, and follow-up at 8 weeks and 12 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pittsburgh Sleep Quality Index (PSQI) score

    PSQI score, 0-21, and higher scores mean a poorer sleep quality.

    Measured: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks.

Secondary outcomes (5)
  1. Insomnia Severity Index (ISI) score

    ISI score, 0-28, and higher scores mean a worse sleep problem

    Measured: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks.

  2. Hamilton Depression Scale (HAMD-17) score

    HAMD-17 score, 0-55, and higher scores mean more severe depression.

    Measured: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks

  3. Hamilton Anxiety Scale (HAMA-14) score

    HAMA-14 score, 0-56, and higher scores mean more severe anxiety

    Measured: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks.

  4. Flinders Fatigue Scale (FFS) score

    FFS score, 0-31, and higher scores mean more severe fatigue

    Measured: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks

  5. Occurrence of adverse events

    Measured: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Compound Ciwujia Granules group, Estazolam and Compound Ciwujia Granules and estazolam in people with Insomnia Disorder, run by Hui Zhu.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 29 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Gang Chen, PhD (+86-17771811588, 250149875@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pittsburgh Sleep Quality Index (PSQI) score (time frame: From enrollment to the end of treatment at 4 weeks, and follow-up at 8 weeks and 12 weeks.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Dec 2025.
