Study summary

In low and middle-income countries, children admitted to hospital are not similarly ill, and do not all have a comparable prognosis. In fact, understanding at first encounter their risk of developing adverse outcomes (including mortality) could allow a more focused management and the tailoring of specific interventions to decrease in hospital mortality, and post discharge adverse longer-term outcomes. This clinical trial, part of the EChiLiBRiST larger project ("Development and validation of a quantitative point-of-care test for the measurement of severity biomarkers to improve risk stratification of fever syndromes and enhance child survival") has the two-fold objective of:

  1. Assessing whether a POINT-OF-CARE rapid triaging test (PoC RTT) based on the quantitative measurement at the bedside of the "prognostic" biomarker sTREM-1 (soluble-triggering receptor expressed on myeloid cells 1) can reliably identify those admitted children with a higher risk of adverse outcomes; and
  2. Assessing whether the therapeutic intervention (the L-arginine precursor, L-Citrulline, key in the nitric oxide biosynthesis), administered orally for 28 days to those children aged 1-\<60 months identified as "moderate-to-high risk" by the prognostic biomarker can improve outcomes as compared to those receiving an indistinguishable placebo.

This second objective will be assessed in a prospective multi-country, multi-site, individually randomised, two-arm, placebo-controlled, double blind clinical trial involving \~888 children 1-\<60m of age admitted to hospital and determined to be at high risk of adverse outcomes by their baseline sTREM-1 levels. The trial will compare the efficacy of a twice-daily dose of L-citrulline syrup vs placebo (200-300mg/kg/day depending on weight-band; for 28 days) in reducing adverse outcomes in children with severe disease. The trial will be running independently but in parallel in two high-mortality settings in Mozambique and in Ethiopia.

Read the detailed description

Children admitted to hospital and meeting the study eligibility criteria who are 0-\<60 months of age will be eligible for study inclusion, and for initial biomarker screening using the study-designed rapid triaging PoC test, based on the measurement of sTREM-1. Study participants aged 1m-\<5 years of age with sTREM-1 values classified as moderate (i.e., "yellow") or high-risk (i.e., "red") in the traffic light risk-stratification system will be randomly allocated (1:1) to receive L-Cit intervention or placebo. All study participants will be followed for 6 months, with study visits at the study hospitals or at home or via phone communication after discharge at day 3, day 5, day 7, day 28, and month 6. The study primary outcome will be "adverse disease outcome", defined as a composite of mortality, incident neurological sequelae, major adverse kidney event at discharge, need for organ support, clinical shock, coma, severe respiratory distress or need for readmission within 28 days after recruitment.

Inclusion criteria

Exclusion criteria

Exclusion Criteria:

  • Admission to hospital for social reasons (and not on account of their disease).
  • Children for which document has not been signed.
  • Known allergy or to any of the study supplements including lactose intolerance or observing a lactose-free diet.
  • Concurrent participation in any other clinical trial.

  • Contraindication for the insertion of a nasogastric tube (NGT) of for the enteral administration of drugs through the NGT in children who cannot tolerate by mouth.
  • Critically sick patient whose prognosis is considered by the clinical researcher as fatal outcome in the following hours after screening.
  • Any other condition determined by the investigators that makes it unlikely that the participant would complete the follow up until day 28 of study.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2025 (actual). Primary completion is estimated for Jun 2027, 17 months after the start.

Of 128 non-industry interventional studies with no phase under Communicable Diseases, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 36. This study's planned 17 months is below that.

Counting every sponsor, half of 144 studies reached it within 21 months; a quarter within 6 and three quarters within 36.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
