About this study

Official title: Effect of Lemborexant on Perioperative Sleep Quality in Patients With Brain Tumor Undergoing Surgery: A Randomized, Double-Blinded, Placebo-Controlled Clinical Trial

This study tests whether lemborexant can improve perioperative sleep quality in people with brain tumor undergoing surgery. Adults with brain tumor scheduled for surgery may join. Participants will be randomly assigned to take lemborexant or a placebo the night before surgery. Researchers will measure sleep quality, anesthesia recovery, pain, postoperative recovery, and other outcomes.

Being tested
Lemborexant 5 mg, placebo
Medical subject headings
Brain Neoplasms, Sleep Initiation and Maintenance Disorders

What is being measured

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

  1. Total Sleep Time (TST) on the Night Before Surgery

    Total sleep time measured by a wrist-worn sleep monitoring device (Huawei smart band) during the night before brain tumor surgery. TST is defined as the total duration of sleep from sleep onset to final awakening, reported in minutes.

    Measured: Night before surgery

Secondary outcomes (11)
  1. Subjective sleep quality

    Richards-Campbell Sleep Questionnaire (RCSQ) score. The RCSQ is a 5-item visual analog scale assessing sleep depth, sleep onset latency, awakenings, time spent awake, and overall sleep quality. Each item scored 0-100, total score is the mean of 5 items, range 0-100, higher scores indicate better sleep.

    Measured: Preoperative day 1, Postoperative days 1-3 (assessed at 8:00-10:00 AM)

  2. Objective sleep quality

    Total sleep time measured by a wrist-worn sleep monitoring device (Huawei smart band) during the night of postoperative day 0. Reported in minutes.

    Measured: Postoperative night 0 (20:00 to 08:00 next day) and Postoperative night 2 (20:00 to 08:00 next day)

  3. Time to Extubation

    Time from the end of surgery to extubation, defined as removal of the endotracheal tube. Reported in minutes.

    Measured: Immediately after surgery

  4. Time to Awakening

    Time from the end of anesthesia to the first response to verbal command. Reported in minutes.

    Measured: Immediately after surgery

  5. Perioperative Anxiety Visual Analog Scale (VAS-A) Score

    Anxiety Visual Analog Scale (VAS-A) score. The VAS-A is a 100-mm horizontal line anchored at 0 (no anxiety) and 100 (worst possible anxiety). The participant marks a point on the line corresponding to their anxiety level. Higher scores indicate greater anxiety. VAS-A score assessed upon entry to the operating room (before induction of anesthesia) and 1 hour after surgery.

    Measured: Perioperative [Upon entry to the operating room (before induction of anesthesia), and 1 hour after surgery]

  6. Postoperative Hospital Anxiety and Depression Scale (HADS) Score

    The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-rated questionnaire comprising two 7-item subscales: anxiety (HADS-A) and depression (HADS-D). Each item is scored from 0 to 3. Each subscale score ranges from 0 to 21, with higher scores indicating greater symptom severity.

    Measured: Postoperative day 1 and 3 (assessed at 8:00-10:00 AM)

  7. Postoperative pain measured by Pain Numeric Rating Scale (NRS) score

    Pain Numeric Rating Scale (NRS) score. The NRS is an 11-point scale ranging from 0 (no pain) to 10 (worst possible pain). Higher scores indicate greater pain intensity.

    Measured: 1 hour after surgery, 24 hours, 48 hours and 72 hours after surgery.

  8. Postoperative Quality of Recovery-15 (QoR-15)

    Quality of Recovery-15 (QoR-15) score. The QoR-15 is a 15-item questionnaire assessing postoperative recovery across physical comfort, emotional state, and physical independence. Each item scored 0-10, total range 0-150, higher scores indicate better recovery quality.

    Measured: Postoperative day 1

  9. Incidence of Postoperative Delirium

    Postoperative delirium will be assessed using the 3-Dimensional Confusion Assessment Method (3D-CAM). The 3D-CAM is a structured diagnostic interview that determines the presence or absence of CAM-defined delirium. Delirium incidence is the number of participants with at least one positive 3D-CAM assessment.

    Measured: Within 3 days after surgery (assessed twice daily)

  10. Pittsburgh Sleep Quality Index (PSQI) Score at 1 Month After Surgery

    Pittsburgh Sleep Quality Index (PSQI) score. The PSQI is a 19-item self-rated questionnaire assessing sleep quality over the past month. Seven component scores are summed to yield a global score ranging from 0 to 21. Higher scores indicate worse sleep quality.

    Measured: 1 month after surgery

  11. Karnofsky Performance Status (KPS) Score at 1 Month After Surgery

    Karnofsky Performance Status (KPS) score. The KPS is a clinician-rated scale ranging from 0 to 100, with scores assigned in 10-point increments. Higher scores indicate better functional status and greater ability to carry out daily activities independently. Assessed by a clinician at 1 month after surgery.

    Measured: 1 month after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lemborexant 5 mg in people with Brain Neoplasms and Sleep Initiation and Maintenance Disorders, run by Beijing Tiantan Hospital.

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 5 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 Oct 2026. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Ruquan Han, PhD (+86 59976660, ruquan.han@ccmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total Sleep Time (TST) on the Night Before Surgery (time frame: Night before surgery). 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 Oct 2026.
