Valproate Alone or in Combination With Quetiapine for Severe COVID-19 Pneumonia With Agitated Delirium
- Conditions
- Covid19Pneumonia, ViralHyperactive Delirium
- Interventions
- Registration Number
- NCT04513314
- Lead Sponsor
- University of Miami
- Brief Summary
The primary purpose of this research is to determine whether Valproate alone, and in combination with Quetiapine, lowers confusion and agitation in persons with severe Corona Virus Disease (COVID)19 pneumonia during weaning from the breathing machine (ventilator). Though Valproate and Quetiapine are often given to persons with severe confusion with agitation, the purpose of this small research study is specifically for: a) persons infected with COVID 2019 on a ventilator whose agitation is not responding to the usual medications (like dexmedetomidine), and b) to reduce the time persons are treated with dexmedetomidine, which requires continuous close monitoring in an ICU.
- Detailed Description
This is a pilot feasibility study involving a randomized, single-blind, controlled comparison scheme examining the efficacy and safety of standard of care (n=10) combined with valproate alone, and in combination with quetiapine (N=10) , in order to reduce the magnitude of agitation associated with COVID 19 delirium as assessed by the RASS scale when weaning from a ventilator, and reduce need for dexmedetomidine as assessed by number of doses of dexmedetomidine administered.

- Other investigational interventions may be permitted
- Known severe allergic reactions to valproate or quetiapine
- History of hepatic encephalopathy or end-stage liver disease (Childs-Pugh class B or worse)

- Platelet count < 50,000/uL at screening and baseline
- Individuals < 18 (infants, children, teenagers)
- Any serious medical condition or abnormality of clinical laboratory tests that, in the investigator's judgement, precludes the patient's safe participation in and completion of the study, e.g. active seizure disorder already receiving treatment with lamotrigine
- Informed consent could not be obtained from the legally authorized representative.

- Arm && Interventions
Group Intervention Description Standard of Care Only Group Standard of Care Patients maintained with mechanical ventilation will be treated with standard of care after cessation of paralytic agents. Treatment Arm Group Standard of Care Patients maintained with mechanical ventilation will be treated with standard of care, plus Valproate on Days 1-7 after cessation of paralytic agents, and then augmented by the addition of Quetiapine beginning Days 3-7 if there are no improvement in RASS score. Treatment Arm Group Valproate Patients maintained with mechanical ventilation will be treated with standard of care, plus Valproate on Days 1-7 after cessation of paralytic agents, and then augmented by the addition of Quetiapine beginning Days 3-7 if there are no improvement in RASS score. Treatment Arm Group Quetiapine Patients maintained with mechanical ventilation will be treated with standard of care, plus Valproate on Days 1-7 after cessation of paralytic agents, and then augmented by the addition of Quetiapine beginning Days 3-7 if there are no improvement in RASS score.
- Primary Outcome Measures
Name Time Method Change from baseline RASS score of +3 or greater Baseline, Day 7 Richmond Agitation Sedation Scale (RASS) score ranges from +4 (combative) to 0 (alert \& calm) to -5 (unarousable).
- Secondary Outcome Measures
Name Time Method Incidence of Treatment Emergent Adverse Events Day 7 Incidence of Treatment Emergent Adverse Events will include:
* QTc duration \> 470 msecs.
* Increase in Liver Function Tests to a Grade 3 or higher using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0.
* Suicidality reported as having a score of moderate or high risk using the Columbia-Suicide Severity Rating Scale Screening (C-SSRS). C-SSRS is a calculated risk assessment tool that scores suicidality from no risk to high risk.Total dose of dexmedetomidine administered Day 7 Total dose of dexmedetomidine administered will be reported from baseline RASS score of +3 or greater.
