The Effect of Alpha-s1 Casein Hydrolysate for Patients With Chronic Insomnia: A Randomized Double-Blind Controlled Trial

This study investigates the impact of Aalpha-s1 casein hydrolysate (ACH; Lactium®) on sleep quality in individuals with chronic insomnia, employing both subjective sleep profiles and objective polysomnography (PSG) recordings.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Insomnia Severity Index (ISI)
Time Frame: 2nd and 4th week
A sleep-related questionnaire, ranging from 0 to 28, where higher scores indicate more acute symptoms of insomnia.
2nd and 4th week
Pittsburgh Sleep Quality Index (PSQI)
Time Frame: 2nd and 4th week
A sleep-related questionnaire, ranging from 0 to 21 with the higher total score indicating worse sleep quality.
2nd and 4th week
Epworth Sleepiness Scale (ESS)
Time Frame: 2nd and 4th week
A sleep-related questionnaire, ranging from 0 to 24. Scores from 0 to 10 reflect normal levels of daytime sleepiness, and scores over 10 are considered to reflect excessive daytime sleepiness.
2nd and 4th week
General Sleep Disturbance Scale (GSDS)
Time Frame: 2nd and 4th week
A sleep-related questionnaire, ranging from 0 (no disturbance) to 147 (extreme sleep disturbance).
2nd and 4th week
