A Study to Evaluate Effects on Sleep and Safety of RE03 in PTSD Patients With Sleep Disturbances

Phase 2
Not yet recruiting
Conditions
Posttraumatic Stress Disorder (PTSD)
Sleep Disturbances and Insomnia
Interventions
Drug: Placebo
Registration Number
NCT06685965
Lead Sponsor
Reconnect Labs
Brief Summary

Post-traumatic stress disorder (PTSD) affects many people who have experienced traumatic events. A common issue with PTSD is severe sleep disturbances, such as nightmares. Current treatments often do not provide sufficient relief, especially for sleep problems. This study aims to determine whether dexmedetomidine - a medication already used in intensive care - can improve sleep quality in PTSD patients.

Detailed Description

Participants spend one screening night followed by three treatment nights in the sleep lab, where they receive either a low dose, a high dose of dexmedetomidine, or a placebo. All participants receive all three options, with only the sequence differing. Participants and the study team are blinded and thus do not know which dose (or placebo) has been assigned.
