Ning Shen Dan Xiang Gao Fang for Heart-Kidney Disharmony Insomnia

A Randomized, Double-Blind, Dual-Control (Internal and External) Clinical Study of Ning Shen Dan Xiang Gao Fang in the Treatment of Insomnia (Heart-Kidney Disharmony Type)

The goal of this clinical trial is to learn if Ning Shen Dan Xiang paste combined with Ejiao (donkey-hide gelatin) works better than Ning Shen Dan Xiang paste combined with agar (placebo substitute) to treat chronic insomnia of the heart-kidney disharmony type in adults. It will also assess safety. The main question is:

- Does Ning Shen Dan Xiang + Ejiao improve sleep quality more than the placebo version, as shown by the change in Pittsburgh Sleep Quality Index (PSQI) score after 8 weeks?

Researchers will compare the two pastes (identical in appearance and taste except for Ejiao) and use published literature data as an additional external control.

Participants will:

Take 20 g of the assigned paste twice daily (morning and evening) for 8 weeks. Attend clinic visits at baseline, week 4, week 8, and 1 week after stopping (week 9 follow-up).

Complete PSQI and ISI questionnaires, keep a daily electronic sleep diary, provide blood/stool samples, and undergo safety monitoring (blood/urine tests, ECG, vital signs, and side effect checks).

Study Overview

• Status: Not yet recruiting
• Conditions: Insomnia
• Intervention / Treatment: Drug: Ningshen Danxiang Donkey-hide Gelatin Medicated Paste; Drug: Ningshen Danxiang Agar Medicated Paste (agar as excipient)

Detailed Description

This is a randomized, double-blind, parallel-group clinical trial with internal and external controls to evaluate the efficacy and safety of Ningshen Danxiang Gelatin Formula (Ningshen Danxiang combined with donkey-hide gelatin) compared to Ningshen Danxiang Agar Formula (Ningshen Danxiang combined with agar placebo) in treating insomnia of the heart-kidney disharmony type according to Traditional Chinese Medicine (TCM). The study aims to assess changes in Pittsburgh Sleep Quality Index (PSQI) scores from baseline after 8 weeks of treatment. Sixty adult participants (>18 years) with chronic insomnia, PSQI >7, and meeting TCM criteria for heart-kidney disharmony will be randomized 1:1 to receive either the experimental formula (20g twice daily) or control (20g twice daily) for 8 weeks. External controls will be synthesized from literature data on placebo and standard treatments for insomnia. Key secondary outcomes include Insomnia Severity Index (ISI), TCM syndrome scores, sleep logs via electronic patient-reported outcomes (ePRO)and rebound rates. Safety will be monitored through adverse events, laboratory tests, and vital signs.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pittsburgh Sleep Quality Index (PSQI)	Use the PSQI scale to assess the subjects' sleep quality . The PSQI consists of 7 dimensions: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. Each dimension is scored from 0 to 3 points, with higher scores indicating greater severity of sleep disturbance. The total PSQI score ranges from 0 to 21. A PSQI score >7 indicates poor sleep quality, while a PSQI score ≤7 indicates good sleep quality.	Baseline, Week 4, Week 8, Follow-up (Week 9)

Secondary Outcome Measures

Change in Sleep Onset Latency (SOL)	SOL is defined as the time interval from the point the patient attempts to fall asleep until the onset of sleep. Data is recorded daily by patients via an electronic Patient-Reported Outcome (ePRO) sleep diary. Unit of Measure: Minutes	Baseline, Week 4, Week 8
Change in Wake After Sleep Onset (WASO)	Assessed via an electronic Patient-Reported Outcome(ePRO) daily sleep diary. WASO refers to the total amount of time the patient spent awake after initially falling asleep and before fully waking up for the day.Unit of Measure: Minutes	Baseline, Week 4, Week 8
Change in Number of Awakenings	Assessed via an Assessed via an electronic Patient-Reported Outcome(ePRO) daily sleep diary. This measure records the total frequency of nighttime awakenings experienced by the patient after initial sleep onset. Unit of Measure: Count (or Number of awakenings)	Baseline, Week 4, Week 8
Traditional Chinese Medicine(TCM) Syndrome Score - Efficacy Evaluation	The TCM symptom grading and quantification criteria include three main symptoms-difficulty falling asleep, vexation and insomnia, and excessive dreaming-which are scored on a 0, 2, 4, or 6 scale according to severity and frequency; the nine secondary symptoms-palpitations, tinnitus, soreness and weakness of the waist and knees, tidal fever with night sweats, vexing heat in the five centers, dry throat, dry mouth, seminal emission in men, and irregular menstruation in women-are scored on a 0-3 scale according to severity and frequency. Tongue and pulse: red tongue tip with scant coating and a thready rapid pulse.The Nimodipine method is used to assess the therapeutic efficacy of TCM syndromes. The syndrome score calculation formula is: ((pre-treatment score - post-treatment score)/pre-treatment score)*100% Effective: All symptoms and signs show improvement; syndrome score reduction ≥50%; Ineffective: Symptoms and signs show no obvious improvement; syndrome score reduction <50%.
