Effects of Caffeine on Intermittent Hypoxia in Infants Born Preterm

March 16, 2015 updated by: Carl Hunt, American SIDS Institute

Pilot Study of Effects of Caffeine on Intermittent Hypoxia in Infants Born Preterm

The purpose of this pilot study is to document the extent to which intermittent hypoxia persists beyond the age of discontinuing clinical methylxanthine, and will assess the effect of caffeine treatment on the number of intermittent hypoxia episodes and the total number of seconds with a hemoglobin oxygen saturation (HbO2 SAT) below 90%.

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Infants with prior clinical treatment with caffeine in the neonatal intensive care unit (NICU) will be enrolled and continuous physiologic data recording of oxygen hemoglobin saturation (HbO2 SAT) and heart rate will begin as early as 33 weeks postmenstrual age (PMA). Randomization will occur when enrolled infants reach a corrected gestational age of at least 34 weeks PMA AND clinical caffeine has been discontinued for at least 5 days. Infants will be randomized to receive caffeine or to continue with usual care. The group randomized to start caffeine will receive an oral loading dose of caffeine citrate of 20 mg/kg on Day #1, followed by a single daily oral maintenance dose of 6 mg/kg starting on Day #2 and continued daily thereafter until 40 weeks PMA. The continuous oximeter recordings will be stopped at the same time. The number of intermittent hypoxia events/hour per week will be compared between the caffeine group and the usual care (no-caffeine) group for each week of physiologic data recordings.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

7 months to 8 months (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Gestational age of 25 + 0 to 32 + 0 weeks PMA at birth, and 34 + 0 to 375 + 6 weeks PMA at randomization
  2. Prior treatment with caffeine based on routine clinical indications, and clinical caffeine now discontinued ≥5 days before randomization
  3. Previously tolerated clinical treatment with caffeine
  4. Breathing room air (no current supplemental O2 treatment; may have previously required respiratory support)
  5. Parental consent to enroll in pilot study

Exclusion Criteria:

  1. Congenital syndrome or other medical diagnosis associated with known risk for neurodevelopmental abnormality, including intraventricular hemorrhage Grade 3 or greater, cyanotic congenital heart disease, confirmed central nervous system infection, or fetal alcohol syndrome
  2. Currently receiving supplemental oxygen, ventilatory support, or nasal airflow therapy
  3. Clinical decision to restart caffeine prior to completing 5 days of continuous physiologic monitoring after clinical caffeine stopped
  4. Anticipated inability to meet protocol requirements

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.
