Brief Summary

This is a clinical study aimed at evaluating the efficacy and safety of Eschscholzia tablets in adults with insomnia disorder symptoms. The study will be conducted at one center, participants will randomly be assigned to either the treatment or placebo. Neither the participants, nor the researchers will know who is receiving the treatment (double-blind). The study is also placebo-controlled, meaning some participants receive a dummy pill instead of the actual treatment, and it involves a parallel-group design, where the treatment and placebo groups are studied at the same time. The study is exploratory, meaning it is investigating new possibilities and is not yet fully conclusive.

The purpose of this study is to determine main efficacy and safety of the newly developed herbal medicinal product Eschscholzia tablets. A total of 100 subjects will be enrolled in the study and assigned to either Eschscholzia tablets or placebo.

The Local Ethics Committee at the clinical site has given their approval for the study to be run.

Male or female participats aged between 18 and 75 years (inclusive), generally healthy and with a self reported history of disturbed sleep on at least 3 nights per week for at least the prior 1 month with a self-reported impact on daytime functioning are allowed to take part in the study.

Overall, the study has the following visits in the clinic, planned for each patient: Screening visit, Study centre Visit 2, Final study centre Visit 3. Between these visits participants will go through a "run-in" period (1 week between Visit 1 and 2) and treatment period (1 month between visit 1 and 3), both at home. Upon visit 2 participants will obtain the study product. They will be asked to administer a daily dose of 2 tablets (either Eschscholzia tablets or Placebo) over a 4-week period, starting from Visit 2 and continuing until Visit 3. Every intake of study product should be noted on the sleep diary pages that the participants obtain.
