Official title: Caffeine for Hypoxic Ischemic Encephalopathy (CHIME Trial)

Run by NICHD Global Network for Women's and Children's Health · NCT06855108 · Data updated 2026-11-12

This trial tests whether giving caffeine to newborns with HIE helps reduce death or severe developmental problems by 18–22 months compared with a placebo.

Is this trial a fit for you?

Likely a good fit

Infants born at ≥36 weeks with birth weight ≥1800 g who meet physiologic and neurologic criteria for moderate-to-severe HIE within six hours of birth.

Probably not a fit

Newborns who lack significant HIE criteria or have conditions that preclude caffeine therapy may not benefit and could be exposed to unnecessary intervention.

What this trial studies

CHIME is a phase 3, randomized, double-blind, placebo-controlled study enrolling newborns with moderate to severe HIE within six hours of birth. Eligible infants are assigned to receive a total of three oral doses of caffeine citrate or placebo, starting with 20 mg/kg, then two 10 mg/kg doses at 24-hour intervals. The trial will compare all-cause mortality or moderate-to-severe neurodevelopmental impairment at 18–22 months between the caffeine and placebo groups. Primary safety and efficacy assessments include neurologic outcomes and organ function in the neonatal period and long-term neurodevelopment. The study is conducted through an international network with multiple collaborating sites and sponsors.

Why it matters

Potential benefit: If successful, caffeine could become a low-cost, accessible treatment to reduce death and neurodevelopmental impairment after HIE.

How similar studies have gone: Previous preclinical and early clinical work suggest caffeine may be neuroprotective, but this direct neonatal HIE approach is being tested in a larger, definitive trial.

Participant Inclusion Criteria:

Infants who meet all the following criteria are eligible for enrollment as study participants:

1. Liveborn infants ≥36 weeks
2. Birth weight ≥1800 grams
3. Meets physiologic criteria for moderate to severe HIE, defined as meeting either of the following two criteria:

   1. Criterion #1: Severe acidosis, defined as an umbilical cord sample or neonatal serum sample within one hour after birth demonstrating any of following criteria:

      * pH \<7.0; or
      * Base Deficit ≥16 mmol/L; or
      * Lactate \>8 mmol/L.
   2. Criterion #2: Participant must meet all of the following three criteria:

   i. Moderate acidosis, defined as an umbilical cord sample or neonatal serum sample within one hour after birth demonstrating any of following criteria:
   * POC pH 7.0-7.15; or
   * Base Deficit 10.0-15.9 mmol/L; or
   * Lactate 6-8 mmol/L.

   ii. Evidence of an acute perinatal event (i.e., placental abruption, intrapartum hemorrhage, cord prolapse, severe fetal heart rate abnormality, uterine rupture).

   iii. Any of the following criteria:
   * 10-minute Apgar \<5; or
   * Need for assisted ventilation initiated at birth and continued for ≥10 minutes
4. Meets neurologic criteria for moderate to severe HIE, defined as a physical exam conducted between one and six hours after birth that meets either of the following criteria:

   1. Moderate to severe encephalopathy in at least three out of six modified Sarnat categories (level of consciousness, spontaneous activity, muscle tone, posture, primitive reflexes, autonomic function); or
   2. A clinical diagnosis of seizure in the first six hours after birth.

Participant Exclusion Criteria:

Infants who meet any of the following criteria are not eligible for enrollment as study participants:

1. Home births
2. Infants who cannot be enrolled, randomized and receive study medication within 6 hours post-delivery
3. Infants with a recognized major congenital anomaly or genetic syndrome that would affect their neurodevelopment.
4. Infants for whom medical care will not be provided based on the severity of their condition or any other condition that would preclude participation per clinical judgement.
5. Infant has received therapeutic hypothermia or there is a clinical plan to initiate active or passive hypothermia for the infant.
6. Infants who will be unavailable to complete follow-up visits.
7. Infants who have received caffeine after delivery.
8. Infants whom the health care team deem ineligible for the study based on likelihood to receive caffeine outside of the study protocol.
9. Enrollment in another trial that will impact participation in this trial.
