NCT ID: NCT04067791

Last Updated: 2020-06-09

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 18 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-08-01

Brief Summary

A study comparing the pharmacokinetics of prolonged-release melatonin versus standard, immediate-release melatonin. Multiple blood draws over a 10-hour period will be analysed to determine the area under the curve, time to peak concentration, peak concentration, absorption rate constant, elimination rate constant, absorption half-life, and elimination half-life. Vital signs, hematology parameters, clinical chemistry parameters, and incidence of adverse events are also analysed.
