Registration Number
NCT06053840
Lead Sponsor
Pharmanovia
Brief Summary

The primary aim of this Real-World Evidence trial is to establish whether short-term (2 weeks) treatment of Chloral Hydrate is effective in patients with severe insomnia which is interfering with normal daily life, and where other behavioural and pharmacologic therapies have failed in a real world setting.

Exclusion Criteria
  • Pregnant or breastfeeding
  • Taking any substances that significantly affect sleep during the 2 week IMP treatment period
  • Starting any new behavioural sleep therapies* during the 2 week IMP treatment period
  • At point of enrolment taking substances that affects sleep at greater than maximum licensed doses
  • Other sleep diagnosed/suspected sleep disorders (restless legs, periodic limb movements, unusual sleep timings (indicative of advanced/delayed sleep, etc), parasomnias
  • Known severe hepatic impairment
  • Known moderate / severe renal impairment / eGFR <60
  • Known severe sleep apnea
  • Known severe cardiac disease
  • Known cardiac disease with QT prolongation
  • History of myocardial infarction in the last 12 months
  • History of stroke or TIA
  • Taking medication that may cause QT prolongation
  • Active gastritis, oesophagitis, gastric or duodenal ulcers or perforation
  • Susceptible to acute attacks of porphyria
  • Hypersensitivity to Chloral Hydrate or to any of the excipients (glycerol, liquid glucose, citric acid, sodium citrate, sodium benzoate, saccharin sodium, essence of passion fruit [containing natural flavouring, artificial flavouring, propylene glycol], and purified water)

  • Patients taking antipsychotic medication in last 12 months
  • History of overdose or attempted overdose
  • History of significant psychiatric disease
  • Patients are taking one of the drugs listed as interacting with Chloral Hydrate and would need to continue taking these during the trial: alcohol, CNS depressants, antipsychotics, hypnotics, anxiolytics/sedatives, antidepressant agents, centrally acting muscle relaxants, narcotic, analgesics, anti-epileptic drugs, anaesthetics and sedative antihistamines, intravenous furosemide, anticoagulants.
  • Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial.
  • Participants who have participated in another research trial involving an investigational product in the past 4 months
  • Participants of childbearing potential (participants who are anatomically and physiologically capable of becoming pregnant), or have a partner of childbearing potential, not willing to use highly effective contraceptives** for the duration of the trial, and who do not confirm a negative pregnancy test prior to starting the IMP.

To investigate the safety of Chloral HydrateAEs and SAEs for the 6 week trial duration

Evaluation of overall safety of Chloral Hydrate by the monitoring of AEs and SAEs

To investigate intervention adherenceDaily intervention adherence survey questions on days 1-14

Daily intervention adherence for the duration of the intervention (2 weeks)

To determine any reductions in 1. Concomitant prescribed medication 2. Over the counter medication used to facilitate sleep1. Concomitant medication assessed at baseline, 1 week, 2 weeks and 6 weeks 2. Over the counter medication used to facilitate sleep assessed at baseline, 1 week, 2 weeks and 6 week

To explore whether Chloral Hydrate will affect Self-rated insomnia severity, assessed at baseline and 2 weeksSelf-rated insomnia severity, assessed at baseline, 1 week and 6 weeks

Change in self-rated insomnia severity, assessed using the Insomnia Severity Index (ISI)

To explore whether Chloral Hydrate will affect anxiety and DepressionHADS scores, assessed at baseline, 1 week, 2 weeks and 6 weeks
