About this study

This study aims to describe a dose-effect relationship of morphine alone and morphine and midazolam administered as continuous infusion in neonates hospitalized in Neonatal intensive care unit and undergoing mechanical ventilation, through PKPD modelling.

Read the detailed description

This study will include all neonates receiving a sedo-analgesia with continuous infusion of morphine alone or morphine and midazolam during mechanical ventilation in 3 French NICUs. Comfort and pain will be assessed by COMFORTneo pain scores and Newborn Infant Parasympathetic Evaluation Index. Morphine, midazolam and their metabolites' concentrations will be determined on samples taken during a planned blood test. Through PKPD modelling, the dose-concentration-effect relationships will be found and interindividual variability of these drugs in neonates and simulate doses needed to achieve comfort in neonates according to their individual characteristics (gestational age, post-natal age, weight etc.).

What is being measured

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

  1. Effective dose for 50% of patients (ED50 ) of morphine in continuous infusion in neonates ventilated in the neonatal intensive care unit

    To evaluate which dose is effective, cComfort will be assessed with COMFORTneo score (scale from 6 to 30 with decreasing score with increasing comfort). The dose-response relationship will be assessed with the correlation between a comfortable score (between 11 and 13) and the effective dose for 50% of patients (ED50), by PKPD modeling

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

Secondary outcomes (6)
  1. Clearance (ml/min/kg) of morphine and midazolam

    Morphine and midazolam serum levels (mg/L) will be used to describe clearance by PKPD

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

  2. Volume of distribution (L/kg) of morphine and midazolam

    Morphine and midazolam serum levels (mg/L) will be used to describe volume of distribution by PKPD modeling

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

  3. Concentration of morphine

    Morphine serum levels (mg/L) will be used to describe inter-individual variability by PKPD modeling

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

  4. Concentration of midazolam

    midazolam serum levels (mg/L) will be used to describe inter-individual variability by PKPD modeling

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

  5. Doses of morphine and midazolam (µg/kg/h)

    PKPD models will be used to simulate doses to determine optimal doses required according to gestational age, postnatal age, corrected age, weight and clinical context

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

  6. To assess pain responses by the Newborn Infant Parasympathetic Evaluation (NIPE) index

    NIPE Index which provides an observer-independent, quantitative assessment of comfort and analgesia based on analysis of heart rate variability. The NIPE Index ranges from 0 to 100 with increasing index with increasing comfort

    Measured: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Dose-effect relationship of morphine +/- midazolam administration in people with Sedation Complication and Mechanical Ventilation in Neonates, run by Centre Hospitalier Intercommunal Creteil at 5 sites in France.

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 5 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 17 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Manon TAUZIN, MD (01 45 17 50 00 ext. 9479, manon.tauzin@chicreteil.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effective dose for 50% of patients (ED50 ) of morphine in continuous infusion in neonates ventilated in the neonatal intensive care unit (time frame: From date of inclusion until the date of end of morphine +/- midazolam treatment, up to 20 weeks). 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 17 Nov 2025.
