Therapeutic Hypothermia for Neonatal Encephalopathy
(TIME Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether cooling therapy, known as therapeutic hypothermia, can enhance early brain development in newborns with mild brain injury due to low oxygen at birth. Researchers aim to determine if babies receiving this treatment show better neurodevelopmental outcomes at about one year old compared to those who do not. The study will compare two groups: one receiving cooling treatment and one maintained at normal body temperature (normothermia). Full-term babies with specific signs of mild brain injury at birth may be suitable candidates for this trial.
As an unphased study, this trial provides a unique opportunity to contribute to groundbreaking research that could improve future treatments for newborns.
Do I have to stop my current medications for the trial?
The trial information does not specify whether participants need to stop taking their current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that therapeutic hypothermia is safe for neonates?
Research has shown that cooling therapy is generally safe for newborns with brain injuries caused by a lack of oxygen. Studies have found that it can lower the risk of death and serious disability. For instance, a major study discovered that cooling therapy reduced the chances of death or severe disability in these newborns compared to those kept at normal body temperature.
The treatment involves cooling the baby's body to about 33.5°C (92.3°F) for 72 hours, which helps protect the brain from further harm. While risks like changes in heart rate or blood pressure can occur, these are usually monitored closely. Overall, cooling therapy is well-tolerated in newborns with moderate to severe brain injuries.12345Why are researchers excited about this trial?
Researchers are excited about therapeutic hypothermia for neonatal encephalopathy because it offers a unique approach to managing moderate-severe hypoxic-ischemic encephalopathy (HIE) in newborns. Unlike the standard care of maintaining normal body temperature, therapeutic hypothermia involves cooling the infant's body to a specific target temperature of 33.5°C for 72 hours using a temperature-regulating blanket. This cooling process is thought to protect the baby's brain by slowing down the metabolism and reducing the risk of brain injury. By offering a new way to potentially minimize brain damage, this method holds promise for improving outcomes in affected newborns.
What evidence suggests that therapeutic hypothermia might be an effective treatment for neonatal encephalopathy?
Research has shown that cooling a newborn's body, known as therapeutic hypothermia, can help treat hypoxic-ischemic encephalopathy (HIE), a condition where a baby's brain receives insufficient oxygen. Studies have found that this treatment can reduce the risk of death or serious disability by 25% in babies with moderate to severe HIE. In this trial, some participants will receive therapeutic hypothermia, a standard treatment for more severe brain injuries in newborns, while others will receive normothermia as a comparator. Although most research focuses on moderate to severe cases, this study examines how therapeutic hypothermia might benefit babies with mild cases.13678

Are You a Good Fit for This Trial?
The TIME Study is for newborns with Mild Hypoxic-Ischemic Encephalopathy, born at or after 36 weeks of pregnancy. They must show signs consistent with an acute event around birth and require resuscitation efforts at 10 minutes old. Babies with genetic issues, born before 36 weeks, weighing less than 1800 grams, or having moderate/severe HIE are excluded.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Normothermia
- Therapeutic Hypothermia
Trial Overview
This study tests the effects of cooling therapy (therapeutic hypothermia) versus normal temperature maintenance (normothermia) on brain health in term neonates with mild brain injury due to oxygen deprivation. Outcomes will be measured by neurodevelopmental progress at about one year old.

Experimental Treatment
Active Control
Therapeutic hypothermia will be achieved using a servo-controlled temperature regulating blanket that is approved for use in neonates and is currently used for the treatment of neonates with moderate-severe HIE. The goal target temperature is 33.5°C ± 0.5°C for 72 hours and the subject will then be rewarmed at a rate of 0.5°C per hour to a goal of 36.5°C.
Normothermia will be achieved using a servo-controlled temperature regulating blanket with the temperature goal of 36.5-37.3°C for 72 hours.
Therapeutic Hypothermia is already approved in United States, European Union, Canada for the following indications:

- Birth asphyxia in newborns
