Clinical Trial Summary

Randomized (1:1 ratio) study of subcutaneous (SC) versus intravenous (IV) fluid rehydration in mildly to moderately dehydrated pediatric patients.

Description:

This is a prospective, randomized (1:1 ratio), open-label, parallel group, multicenter, multi-national, study of SC versus IV fluid rehydration in mildly to moderately dehydrated pediatric patients treated in the Emergency Department (ED), inpatient pediatric unit, and/or outpatient urgent care facility. It is expected that up to 186 patients, in order to achieve 148 evaluable patients, will be randomized in a 1:1 ratio to receive isotonic fluid rehydration by either SC administration with hylenex (150 Units) or IV without hylenex.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Total Volume of Fluid Administered at a Single Infusion Site, From the Start to the Cessation of Fluid Administration, for All Randomized Participants	It was anticipated that most participants in this study would be hydrated through only one infusion site. For participants who received fluid at more than one administration site, a single infusion site was defined as the anatomical site at which the majority of the total infusion volume was infused. The term "anatomical site" was designated as: 1) the back; 2) left thigh; 3) right thigh; 4) abdomen; or 5) chest.	During the infusion (single bolus dose of hylenex [1 hr], followed by subcutaneous fluid for 1 hour to 72 hours)
Primary	Mean Total Volume of Fluid Administered at a Single Infusion Site, From the Start to the Cessation of Fluid Administration, for Non-rescued Participants	It was anticipated that most participants in this study would be hydrated through only one infusion site. For participants who received fluid at more than one administration site, a single infusion site was defined as the anatomical site at which the majority of the total infusion volume was infused. The term "anatomical site" was designated as: 1) the back; 2) left thigh; 3) right thigh; 4) abdomen; or 5) chest. Participants randomized to receive intravenous isotonic fluid were permitted to receive subcutaneous fluid administration by hylenex-facilitated infusion as rescue.

Secondary	Mean Total Volume of Fluid Administered at All Infusion Sites, From the Start to the Cessation of Fluid Administration, for All Randomized Participants Achieving > 200 mL	It was anticipated that most participants in this study would be hydrated through only one infusion site. For participants who received fluid at more than one administration site, a single infusion site was defined as the anatomical site at which the majority of the total infusion volume was infused. The term "anatomical site" was designated as: 1) the back; 2) left thigh; 3) right thigh; 4) abdomen; or 5) chest. The label for hylenex indicated precautionary wording recommending an upper limit on the volume of fluid (200 mL) administered subcutaneously to infants less than 3 years of age. In October 2008, the Food and Drug Administration (FDA) removed this wording from the label, thus negating the need for these data and associated analyses. The protocol was amended to reflect this label change; thus, this analysis was not conducted.
