Study summary

Bacterial infections among young infants, including sepsis, meningitis, and pneumonia, continue to cause a substantial number of deaths globally. Zinc supplementation in combination with standard antibiotic therapy may represent a new intervention to reduce mortality and improve treatment outcomes for young infants with clinical severe infection.

The Investigators will conduct a randomized, double-blind, placebo-controlled trial of zinc supplementation among young infants 0-59 days with severe clinical infection. The trial will enroll 3,250 Tanzanian infants hospitalized with clinical severe infection as defined by WHO Integrated Management of Childhood Illness (IMCI) guidelines. Enrolled infants will receive standard clinical management including antibiotics and will be randomized to receive either a 14-day course of twice-daily 5 mg elemental zinc (10 mg per day) or a matching placebo regimen.

  • Diagnosis of clinical severe infection (CSI)
  • Ability to feed enterally
  • Intend to stay in the study area for 90 days
  • Provided

Exclusion criteria

Exclusion Criteria:

  • Receipt of antibiotics for >24 hours before enrollment
  • Diarrhea at enrollment
  • Signs suggestive of serious illness/condition that is not clinical severe infection
  • Previously enrolled in the trial

Terms in these criteria, in plain language(1)

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.

What researchers measure

Primary outcomes

  1. Death

    All-cause infant death

    Time frame: 90 Days

  2. Treatment Failure

    A composite endpoint of death during initial period of hospitalization, the need for additional respiratory support (either mechanical ventilation, or positive end expiratory pressure support) or the use of vasoactive medicines to support blood pressure or need to change antibiotics during the initial hospitalization

    Time frame: From date of randomization until the date of first documented treatment failure or date of death from any cause during the initial hospitalization, whichever comes first, assessed up to 90 days

Secondary outcomes

  1. Death during initial hospitalization

    All-cause mortality during initial hospitalization

    Time frame: Randomization to the date of initial hospitalization discharge, assessed up to 90 days

  2. Duration of initial hospital stay

    Hours from randomization to initial hospitalization discharge

    Time frame: Randomization to Day 90

  3. Duration of signs of clinical severe infection

    Hours from randomization to the absence of any sign of clinical severe infection

    Time frame: Randomization to Day 90

  4. Diarrhea during initial hospital admission

    Clinical diagnosis based on three or more loose or watery stools in the past 24 hours

    Time frame: Randomization to the date of initial hospitalization discharge, assessed up to 90 days

  5. Rate of vomiting related to regimen dosing

    Vomiting observed by study staff within 30 minutes of regimen dosing

    Time frame: Randomization to Day 15

  6. Re-hospitalization

    Infant admitted and stayed overnight in health facility after being discharged from initial hospitalization

    Time frame: Date of initial hospitalization discharge to Day 90

  7. Presence of any sign of possible severe bacterial infection at Day 15

    Presence of a clinical sign of possible severe bacterial infection, including: high body temperature ≥38°C, low body temperature \<35.5°C , severe chest indrawing, movement only on stimulation or no movement at all, stopped feeding well or unable to feed at all, or convulsions.

    Time frame: Day 15

  8. Presence of any sign of possible severe bacterial infection at Day 90

    Presence of a clinical sign of possible severe bacterial infection, including: high body temperature ≥38°C, low body temperature \<35.5°C , severe chest indrawing, movement only on stimulation or no movement at all, stopped feeding well or unable to feed at all, or convulsions.

    Time frame: Day 90

  9. Proportion of Children with Diarrhea at Day 15 or Day 90

    Maternal report of three or more loose or watery stools in the past 24 hours

    Time frame: Day 15 and Day 90

  10. Infant length-for-age z-score at Day 15

    Infant length-for-age z-score by WHO Child Growth Standards

    Time frame: Day 15

  11. Infant length-for-age z-score at Day 90

    Time frame: Day 90

  14. Infant weight-for-length z-score at Day 15

    Time frame: Day 15

  15. Infant weight-for-length z-score at Day 90
