ClinicalTrials.Gov PRS Field-by-Field Checklist & Results Module Templates - REMIMID-ICU

This trial evaluates whether remimazolam provides superior sedation quality compared with midazolam in adults receiving invasive mechanical ventilation with ongoing vasopressor support. The primary outcome is the percentage of time within target sedation (RASS -3 to -5) without rescue sedative during the first 48 hours after randomization. Key secondary outcomes include vasopressor exposure (NEE AUC 0-48h), time to awakening, delirium incidence, ventilator-free days, and 28-day mortality.

  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion

  • Age ≥18 years.
  • Invasive mechanical ventilation at randomization; anticipated continuous sedation ≥24 hours.

  • At least one sign of hypoperfusion (e.g., lactate >2 mmol/L, oliguria, mottled skin, or altered mentation) unless solely due to sedation.

Exclusion

• Known pregnancy; status epilepticus; severe hepatic failure (Child-Pugh C) or on ECMO; refractory hypoxemia requiring prone position at randomization; benzodiazepine hypersensitivity; need for continuous neuromuscular blockade >24h at baseline; moribund not expected to survive 24h; investigator judgement.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Arm A - Remimazolam
Continuous IV infusion; start 0.10 mg/kg/h and titrate every 15-30 minutes in 0.025-0.05 mg/kg/h steps to target RASS -3 to -5 (allowable range -2 to -5 for clinical safety). Maximum typical rate 0.20 mg/kg/h; temporary higher rates permitted per protocol for breakthrough agitation.
Continuous IV infusion; start 0.10 mg/kg/h and titrate every 15-30 minutes in 0.025-0.05 mg/kg/h steps to target RASS -3 to -5 (allowable range -2 to -5 for clinical safety). Maximum typical rate 0.20 mg/kg/h; temporary higher rates permitted per protocol for breakthrough agitation.
Experimental: Arm B - Midazolam
Continuous IV infusion; start 0.04 mg/kg/h and titrate every 15-30 minutes in 0.01-0.03 mg/kg/h steps to target RASS -3 to -5 (allowable range -2 to -5). Maximum typical rate 0.20 mg/kg/h per protocol.
Continuous IV infusion; start 0.04 mg/kg/h and titrate every 15-30 minutes in 0.01-0.03 mg/kg/h steps to target RASS -3 to -5 (allowable range -2 to -5). Maximum typical rate 0.20 mg/kg/h per protocol.
