About this study

Official title: Not for Profit, Monocentric, Open Label Trial of Lorazepam, Randomized to Three Different Sequences of Boli and Continuous Infusion, for Sedation of Children Aged ≥1 and <12 Years Admitted in Intensive Care and Mechanically Ventilated.

The aim of this study is to better define the pharmacokinetic and pharmacodynamic profile of lorazepam for the analgosedation in pediatric intensive care unit. This will help to better define the dosages and administration modalities (bolus or continue infusion) required to achieve analgosedation with lorazepam in pediatric patients undergoing mechanical ventilation.

Read the detailed description

The prolonged use of certain sedative drugs such as midazolam, whose metabolism is associated with the production of active metabolites, can lead to difficult management of sedative therapy and ventilatory weaning. The active metabolites, whose production is variable, determine in fact a difficulty in establishing a precision therapy, thus making it necessary to identify new molecules for sedation in pediatric intensive care unit (PICU). Lorazepam (LZ) is a benzodiazepine with an intermediate duration of activity, administered by continuous infusion or intermittent bolus, which has the advantages of higher potency compared to other benzodiazepines, a low cost and a metabolism that does not produce active metabolites. However, the presence of propylene glycol (PG), an excipient present in intravenous LZ formulations, although generally well tolerated, is potentially associated with episodes of tissue toxicity due to accumulation phenomena; this may represent a risk in cases where LZ is administered in high doses. This study, based on pharmacokinetic models obtained from data already available in the scientific literature, aims to define the pharmacokinetic and pharmacodynamic characteristics of LZ for the analgosedation of pediatric patients admitted to intensive care and subjected to mechanical ventilation. Preliminary evaluation of sedative efficacy will be carried out through COMFORT-B scale assessment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Lorazepam Pharmacokinetics (AUC)

    AUC of Lorazepam

    Measured: 72 hours from enrollment

Secondary outcomes (21)
  1. Analgosedative efficacy of Lorazepam

    Frequency of responder patients (COMFORT-B scale score between 11 and 22 and alertness score between 2 and 3)

    Measured: 72 hours from enrollment

  2. COMFORT-BEHAVIOURAL (COMFORT-B) scale

    Median (IQR) of COMFORT-B scale score and alertness score. The COMFORT BEHAVIOURAL (COMFORT-B) SCALE consists of six items: alertness, calmness, respiratory response (for children undergoing mechanical ventilation), body movements, facial tension and muscle tone. Each item goes from 1 to 5, assessing the different intensities. The sum of the six ratings leads to a final score ranging from a minimum of 6 to a maximum of 30. A patient is considered to be under-sedated in case of COMFORT-B scores of 23 or higher, over-sedated in case of COMFORT-B scores of 10 or lower.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lorazepam 4 mg/ml in people with Analgesia, run by Bambino Gesù Hospital and Research Institute.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Marco Marano, MD (0668592765 ext. +39, marco.marano@opbg.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Lorazepam Pharmacokinetics (AUC) (time frame: 72 hours from enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Nov 2020.
