Safety and Dose Escalation Study of Zinc Supplementation in Critically Ill Children

August 19, 2019 updated by: UCSF Benioff Children's Hospital Oakland

A Safety and Dose-escalation Study of Zinc Supplementation in Pediatric Critical Illness

The purpose of the study is 1) to determine whether administration of intravenous zinc to critically ill children is safe, and 2) to determine an appropriate dose of zinc supplementation.

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

Our recently published studies in children with septic shock demonstrated that pediatric septic shock is characterized by large scale repression of genes that either directly depend on normal zinc homeostasis or directly participate in zinc homeostasis. Functional validation studies demonstrated that nonsurvivors of pediatric septic shock have abnormally low serum zinc concentrations. A follow-up pilot study in a general population of critically ill children demonstrated that the presence of low plasma zinc concentrations is a prevalent problem in critically ill children. In addition, low plasma zinc concentrations correlate inversely with indices of inflammation and directly with the number of organ failures. These preliminary data, coupled with the expected safety of zinc supplementation, provided the rationale for a double blinded, prospective, placebo-controlled trial of zinc supplementation in critically ill children, with the two primary study endpoints to assess efficacy being highly clinically relevant: reduction of the lymphopenia rate and improvement of glucose homeostasis. Although the proposal was well-received, the primary concern precluding funding of this trial were lack of safety and dosing data for intravenous zinc. We have therefore developed a proposal for a Phase I/II study of safety and pharmacokinetics to address these concerns. It is anticipated that data generated through this proposal will provide the necessary preliminary data to re-submit our application for an interventional efficacy trial of zinc supplementation in critically ill children

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.

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
Plasma Zinc Concentration Over Time
Time Frame: 7 days
Plasma Zinc levels were measured daily during the seven day study period in each group.
7 days
New Fever
Time Frame: 7 days
Because of reports of fever in patients wiht zinc overdoses, we monitored patients for new fever while on supplementation
7 days

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.
Outcome Measure
Measure Description
Time Frame
Glucose Homeostasis
Time Frame: 7 days
Patients were assigned a score based on glucose range to take into account the degree of hyperglycemia as well as the need for insulin over the course of the 7 day study period. This score is an ordinal scale ranging from 1 to 5, with a score of 1 indicating no hyperglycemia, and 5 indicating severe hyperglycemia despite insulin administration.
