Study of Subcutaneous Hydration Enabled by Human Recombinant Hyaluronidase (Hylenex)

The INcreased Flow Utilizing Subcutaneously-Enabled Normal Saline and Lactated Ringer's (INFUSE-NSLR) Study: A Phase IV, Double-Blind, Randomized Study of Subcutaneous Hydration Enabled by Human Recombinant Hyaluronidase (Hylenex) in Volunteer Subjects

• Status: Completed
• Phase: Phase 4
• Study type: Interventional
• Enrollment: 15 (actual)
• Sponsor: Halozyme Therapeutics · Industry
• Sex: All
• Age: 18 Years – 60 Years
• Healthy volunteers: Accepted

Summary

Randomized, double-blinded study that will evaluate the tolerability, safety, and flow rates of different solutions subcutaneously (SC) infused and preceded by human recombinant hyaluronidase (hylenex) 150 units. In Stage 1, the comparison will be Normal Saline (NS) solution to Lactated Ringer's (LR) solution. Each subject will receive 500 milliliters (mL) of solution, consisting of NS in one thigh and LR in the other thigh. Immediately prior to the infusions, each thigh will have 150 units of hylenex. In Stage 2, the comparison will be NS solution and buffered NS solution.

Detailed description

This Phase IV, randomized, double-blinded study in volunteer subjects to evaluate the tolerability, safety, and flow rates of different solutions subcutaneously (SC) infused and preceded by human recombinant hyaluronidase (hylenex) 150 units. The study will be conducted in two sequential stages. In Stage 1, the comparison will be NS solution to LR solution. Each subject will receive simultaneous SC infusions of 500 mL (from a 500 mL bag) of solution in each anterior thigh, consisting of NS in one thigh and LR in the other thigh. The thighs (left vs. right) to receive NS and LR will be randomized and double blinded. Immediately prior to the infusions, each thigh will have 150 units of hylenex simultaneously injected. Tolerability will be assessed based on the subject's self-assessment of discomfort on a visual analog scale (VAS). Safety will be assessed by physical examination targeted at infusion sites, vital signs, and adverse events. The amount of fluid infused will be assessed by weighing the infusion bag, fluid and tubing at designated time points, and allowing the determination of flow rate. Stage 2 will be conducted only if the observed Stage 1 VAS mean maximum pain score is at least 25 mm higher for one solution compared to the other. Stage 2 will evaluate the tolerability, safety, and flow rates of subcutaneously infused NS solution and buffered NS solution.
