Brief summary
Insomnia is a disorder where people are having trouble sleeping and can include difficulty falling asleep, staying asleep and waking up too early, as well as having unrefreshing sleep. CHI-921 is a cannabis extract in sunflower oil produced as a treatment for insomnia. This trial is designed to evaluate the efficacy and safety of CHI-921 on people with insomnia.
Detailed description
The study is designed to: 1. Evaluate the patient-reported sleep latency and patient-reported wake after sleep onset after 3 weeks per treatment dose with CHI-921 compared to placebo. 2. To evaluate the effects of CHI-921 compared to placebo on PSG sleep architecture. 3. To evaluate the effects of CHI-921 compared to placebo on Patient Global Impression of change. 4. To evaluate the daytime residual effects that may be associated with CHI-921 as compared to placebo during the double-blind treatment period using patient's morning and evening questionnaire, Clinical Global Impression of change, Insomnia Severity Index, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale as well as the Rey Auditory Verbal Learning Test and Digit Symbol Substitution psychometric tests. 5. To assess the effect on sleep of abruptly discontinuing CHI-921 compared to placebo (during run-out period). 6. To evaluate the clinical safety and tolerability of CHI-921 compared to placebo. 7. Evaluation of the accuracy of sleep data obtained by actigraphy as compared to traditional PSG.

Normal vital signs as follows: * Sitting systolic blood pressure (SBP) between 90 and 140 mmHg, inclusive * Sitting diastolic blood pressure (DBP) between 55 and 90 mmHg, inclusive * Pulse rate between 50 and 100 bpm inclusive 5. Willing to comply with all study requirements and procedures for the duration of the clinical study 6. Willing to comply with the study restrictions including: * Adherence to concomitant drug washout requirements, as applicable, for the duration of the clinical study * Willing to abstain from alcohol for the duration of the clinical study * Willing to abstain from caffeine 10 hours before each recording * If a smoker, willing to abstain from smoking at night from approximately 10 pm to 8 am for the duration of the clinical study 7. Female subjects who: * Are postmenopausal, with amenorrhea for at least 1 year before the screening visit, * Are surgically sterile, OR * If of childbearing potential agree to practice effective double barrier methods of contraception, from the time of the signing of informed consent through the last dose of study drug and for 30 days after dosing stops (1 ovulatory cycle), or agree to completely abstain from intercourse * Males with female partners of childbearing potential are also expected to practice effective barrier methods of contraception from the time of signing informed consent through the last dose of study drug and for 30 days after dosing stops. 8. Self-reported bedtime between 9 pm and midnight on 4-7 nights per week 9. Based on the PSG recordings during the screening nights (V2; SN1 and SN2), one of the following criteria must be present: 1. Mean WASO calculated on SN1 and SN2 \> 30 min or 2. Mean LPS: calculated on SN1 and SN2 \> 30 min
Exclusion criteria
1. Body mass index \> 32 calculated from patient's height (m) and weight (kg); weight (kg)/square height (m²) 2. Presence of a sleep disorder (for sleep apnea syndrome, an apnea-hypopnea index \> 15 per hour of sleep on the first screening night will be used as an exclusion criterion; for periodic limb movement disorder, an index of periodic limb movements during sleep associated with an arousal \> 10 per hour of sleep on the first screening night will be used as an exclusion criterion) 3. Patients with a history of epilepsy or seizures (not including benign neonatal and childhood convulsions) 4. Serious head injury or stroke within the past year 5.

Evidence of any clinically significant, severe or unstable, acute or chronically progressive medical or surgical disorder (including planned medical procedures that may impact sleep), or any condition that may interfere with the absorption, metabolism, distribution, or excretion of the study drug, or may affect patient safety 7.
