Effect of Early L-Carnitine Supplementation on Neurodevelopmental Outcomes in Very Preterm Infants

July 22, 2022 updated by: Montefiore Medical Center

A Double-Blind, Controlled, Randomized Clinical Trial of the Effect of Early L-Carnitine Supplementation on Neurodevelopmental Outcomes in Very Preterm Infants

Preterm infants are vulnerable to brain injury, nutritional deficiencies and poor early growth which places them at increased risk for developmental problems later in life. The micronutrient carnitine, which is present in breast milk and stored in the fetus late in pregnancy, has been shown to protect against brain injury in animal studies. Without supplementation, almost all preterm infants develop carnitine deficiency soon after birth. Thus it is important to determine if carnitine supplementation protects against brain injury and improves developmental outcomes in these vulnerable preterm infants. We hypothesize that preterm infants supplemented early with L-carnitine while receiving parenteral nutrition will not develop carnitine deficiency and will have improved growth in the first two weeks of life and higher scores on developmental tests when compared to control infants who did not receive carnitine.

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.

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.

Arms and Interventions

Participant Group / Arm

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Placebo Comparator: 5% dextrose
Infants randomized to the placebo group will receive 5% dextrose intravenously. If infant is receiving 100 cc/kg/day of enteral feeds before the supplementation endpoint, an equivalent volume of placebo (5% Dextrose) will be given to the study patients.
Drug: 5% Dextrose
Infants will receive 5% dextrose (placebo) three times a day (volume equivalent to the experimental drug) intravenously for a minimum of 2 weeks or until they achieve enteral feeding volume of 100 cc/kg/day. If infant is receiving 100 cc/kg/day of enteral feeds before the supplementation endpoint, an equivalent volume of enteral placebo (5% Dextrose) will be given to the study patients.
Experimental: L-carnitine
Infants randomized to the study group will receive L-carnitine intravenously. If infant is receiving 100 cc/kg/day of enteral feeds before the supplementation endpoint, an equivalent dose of enteral L-carnitine will be given to the study patients.
Drug: L-carnitine
Infants will receive L-carnitine 50 micromoles/kg/day, divided into three doses, intravenously for a minimum of 2 weeks or until they achieve enteral feeding volume of 100 cc/kg/day. If infant is receiving 100 cc/kg/day of enteral feeds before the supplementation endpoint, an equivalent dose of enteral L-carnitine will be given to the study patients.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to Regain Birthweight in Infants Who Receive L-carnitine Supplementation Compared to Controls
Time Frame: up to 3 weeks of age
Time (in days) for infants in both arms of the study to regain birthweight - data presented as mean +/- SD.
up to 3 weeks of age
Neurodevelopment Indices in Infants Who Receive L-carnitine Supplementation Compared to Controls (NNNS)
Time Frame: at term equivalent age (38 weeks +/-1 week corrected age)
NICU Network Neurobehavioral Scale (NNNS) was administered to study participants at term equivalent age (38 weeks +/-1 week corrected age). The NNNS is a 128-item standardized assessment to evaluate the neurobehavioral status of healthy and high-risk infants. Summary scores include: Attention (range 2.25-8; higher score better), Arousal (range 2-5; lower score better), Regulation (range 3.31-6.92; higher score better), Handling (range 0-0.88; lower score better), Quality of movement (range 3-6; higher score better), Excitability (range 0-9; lower score better), Lethargy (range 0-12; lower score better), Nonoptimal reflexes (range 0-10; lower score better), Asymmetric reflexes (range 0-6; lower score better), Hypertonicity (range 0-2; lower score better), Hypotonicity (range 0-3; lower score better), and Stress/abstinence scale (range 0-0.22; lower score better).
at term equivalent age (38 weeks +/-1 week corrected age)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
