Trial summary

Despite a greater understanding of NEC physiopathology, modest progress has been done in terms of intervention and prevention of the disease over the past three decades, being the mortality rate unchanged. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 44 weeks
  • All sexes
  • No healthy volunteers
  • Child

Study population: Investigators will use surgically-resected intestinal samples from NEC patients and gestational age-matched non-NEC surgical controls with intestinal resection for other reasons than NEC to conduct various analysis. For comparative studies, Investigators aim to grow enteroids from intestinal tissues freshly collected from preterm and term babies with an age limit of 44 weeks of postmenstrual age (PMA). Group 1: intestinal samples from small and/or large bowel in NEC preterm and term babies. Group 2 (Control group): Age- and intestinal area-matched (small and/or large bowel) No NEC babies, which have surgical resection for other reason than NEC

Who may be able to join

  • Infants, with a postconceptional age below 44 weeks of gestation, undergoing a clinically indicated intervention of partial intestinal resection while hospitalized at the NICU of the Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico.

Who cannot join

  • Infants presenting a devastating damage of the intestine

About this study

Official title: Development and Use of a Tissue and Human Enteroid Biorepository to Study the Pathophysiology of Neonatal Necrotizing Enterocolitis

Despite a greater understanding of NEC physiopathology, modest progress has been done in terms of intervention and prevention of the disease over the past three decades, being the mortality rate unchanged.

Investigators intend to leverage our knowledge and technical expertise developed with fetal enteroids to further investigate the processes leading to NEC by deriving and performing functional studies on human intestinal enteroids generated from intestinal resection for therapeutic reasons in NEC and non-NEC patients

  1. Generate a tissue biorepository composed of: enteroids and other lamina propria cells
  2. Comparative studies of the gene expression profile of tissue, epithelial enteroids and underlying lamina propria of NEC, non-NEC, hypoxic and non-hypoxic infants
  3. In vitro functional studies for the evaluation of critical factors in NEC pathophysiology
  4. In vitro functional studies to identify the activation of processes leading to intestinal epithelium necroptosis and/or apoptosis in bacteria challenged and hypoxic conditions
  5. Correlative studies of the impact of perinatal variables on the intestinal barrier functionality at baseline and challenged with pathogens
  6. In vitro comparison of the intestinal barrier functionality in infants complicated by condition of prenatal hypoxia versus non hypoxic infants
  7. Validation the NEC enteroids as an in vitro model for the identification of treatments and prevention of NEC

What is being measured

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

  1. Comparative studies of gene expression

    assess the gene expression profile of tissue, epithelial enteroids and underlying lamina propria derived from NEC, non-NEC (further classified as hypoxic and non-hypoxic infants).

    NB: the unit of analysis will be the organoids derived from patients' tissues Investigators expect to be able to derive 1 cell line per patient, and the number of derived organoids will depend from the viability of individual cell lines.

    Measured: 2 years

  2. functional studies barrier functionality

    evaluation of barrier functionality at the baseline and in enteroids-derived monolayers challenged with pathogens, dead bacteria (as postbiotics), LPS, pharmacological agents, enteral nutrients and to evaluate innate immune response and barrier functionality as previously investigated in fetal enteroids and the contribution of myofibroblast, immune and ENS to the immune response

    Measured: 2 years

  3. functional studies on cellular death

    studies to identify the activation of processes leading to intestinal epithelium necroptosis and/or apoptosis in bacteria challenged and hypoxic conditions

    Measured: 2 years

  4. Correlative studies of the impact of perinatal variables

    Assess how the perinatal features (expression of the neonatal phenotype, as IUGR, chorionamnionitis, perinatal hypoxia) on the intestinal barrier functionality at baseline and challenged with pathogens

    Measured: 2 years

  5. compare the intestinal barrier functionality in pathological conditions

    comparison of the intestinal barrier functionality in infants complicated by condition of prenatal hypoxia versus non hypoxic infants

    Measured: 2 years

  6. Validation of the enteroid NEC model

    Validate the NEC enteroids as an in vitro model for the identification of treatments and prevention of NEC.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Enterocolitis, Necrotizing and Prematurity, run by Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico.

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 1 inclusion and 1 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 17 Sep 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.

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 Paola Roggero, MD PHD (+393472777054, paola.roggero@unimi.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparative studies of gene expression (time frame: 2 years). The study lists 6 primary outcomes in all. 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 Sep 2020.
