This clinical study aims to understand the effects of a medication called Neurexan on sleep patterns and stress in people with short-term insomnia. The study involves comparing Neurexan to a placebo - a tablet that looks like Neurexan but lacks active ingredients. The main goal of the study is to determine if Neurexan can enhance sleep efficiency in those with short-term insomnia. Sleep efficiency, which is the proportion of time spent asleep in relation to total time in bed, including attempts to fall asleep, will be assessed through Polysomnography (PSG). PSG examines various sleep characteristics such as brain activity, muscle and heart activity, and breathing. Participants will take either Neurexan or the placebo for 14 days. Sleep efficiency will be evaluated using PSG before and after the treatment period. Additionally, sleep quality-related factors will be investigated using PSG data, sleep diaries, and participant-completed questionnaires. The study will also investigate Neurexan's impact on stress levels. This will be assessed using the Cold Pressor Test, which measures stress through having the participant immerse their hand into ice water, and measuring changes in blood pressure and heart rate, both indicators of stress. In addition, blood and saliva samples collected before and after treatment with Neurexan or placebo, will be analyzed for stress-related hormones such as cortisol. Patient questionnaires and Electroencephalography (EEG), a non-invasive brain activity recording, will further assess stress symptoms. Researchers will analyze data related to sleep efficiency, sleep quality, and stress symptoms. By comparing outcomes before and after Neurexan or placebo treatment, the study aims to detect improvements in these areas. Positive results with Neurexan but not with the placebo would provide robust evidence for Neurexan's efficacy in addressing sleep and stress management issues. This study contributes valuable insights into Neurexan's potential benefits for individuals with short-term insomnia.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change from baseline in Sleep Efficiency. | Sleep Efficiency (SE) assessed using Polysomnography (PSG) is calculated as the ratio of total sleep time to time in bed (i.e., both sleeping and attempting to fall asleep or fall back asleep). SE will be assessed at baseline prior to treatment with investigational drug, then again 14 days later following investigational drug treatment. | 14 days | |
Secondary | Change from baseline in sleep pattern characterized by Number of Awakenings. | Sleep pattern characterized by Number of Awakenings (NWAK) will be assessed using Polysomnography (PSG) at baseline prior to treatment with investigational drug, then again 14 days later following investigational drug treatment. | 14 days | |
Secondary | Change from baseline in daytime performance assessed by Epworth Sleepiness Scale patient questionnaire. | The Epworth Sleepiness Scale (ESS) is a validated measure of a patient's general level of daytime sleepiness. The patient rates their tendency to become sleepy in 8 different situations commonly encountered in daily life, on a scale of 0 (no chance of dozing) to 3 (high chance of dozing). The total ESS score is the sum of each of the 8 scores, with a total score of 0 to 24. The higher the score, the higher the patient's level of daytime sleepiness. A number in the 0-9 range is considered to be normal, whereas a number in the range of 10-24 indicates that expert medical advice should be sought. The ESS will be completed electronically at baseline prior to treatment with investigational drug, then again 14 days later following investigational drug treatment. | 14 days | |
Secondary | Ecological Momentary Assessments - continuous daily stress assessment. | Patients' perceived stress levels (Ecological Momentary Assessments - EMAs) will be reported electronically at the Screening Visit prior to randomization and treatment with investigational drug, then daily throughout the trial until the Day 28 Follow-up Visit. The questionnaire records levels of stress on a scale of 0 (Not stressed at all) to 10 (Very stressed), as well as the severity of stress (0 - Not severe to 10 - Very severe), how well the patient is managing the stress (0 - Not well to 10 - Very well) and the cause(s) of the stress. No sum score will be calculated. | 36 to 56 days |
