About this study

Official title: 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

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.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Participant's Assessment of Discomfort at the Infusion Site on a Visual Analog Scale (VAS)

    Participant's self-assessment of discomfort at the infusion site by means of a validated VAS with a range of 0 millimeters (mm) (no discomfort) to 100 mm (worst possible discomfort), for the comparison of subcutaneous (SC) infusion of normal saline (NS) versus Lactated Ringer's (LR), each following an SC slow-push injection of 150 Units (U) Hylenex.

    Measured: Approximate times which ranged from zero minutes at baseline to maximal post-infusion of 240 minutes on Day 1

Secondary outcomes (5)
  1. Number of Participants Assessed for Safety Measures

    Safety outcome measures included adverse events (AEs), physical examinations (targeted physical examination included lung auscultation for rales, checking for edema, evaluation of infusion sites, positives on a review of systems, and follow-up of findings from previous physical examinations), and vital signs (systolic blood pressure, diastolic blood pressure, heart rate, and respiration rate).

    Measured: Baseline, Mid-Infusion Right and Left, Post-Infusion Right and Left, Discharge Right and Left (up to approximately 8 days)

  2. Average Infusion Flow Rate (Milliliters Per Hour [mL/hr]) Derived From the Time to Infuse up to 500 mL of Solution

    The infusion flow rate (mL/h) was derived from the time to subcutaneously (SC) infuse up to 500 mL of NS or LR solution (following SC injection of 150 Units hylenex) by measuring the change in weight of the infusion bag, fluid, and tubing.

    Measured: During infusion on Day 1

  3. Percent Change From Baseline Thigh Circumference to Maximum Post-Baseline Thigh Circumference at Infusion Sites

    Thigh circumference was measured in centimeters at 7 time points before, during, and after subcutaneous infusion of 500 mL NS or LR solution.

    Measured: Before the infusion, during the infusion, after the infusion, and discharge (Day 1)

  4. Time From the Beginning of Infusion Until the Thigh Circumference Returns to Within 5% of Baseline Circumference

    Thigh circumference was measured at the level of the angiocatheter with a flexible measuring tape prior to infusion initiation (Baseline), at the midpoint for each infusion, and at the end of each infusion.

    Measured: Before the infusion (Baseline) until discharge (Day 1)

  5. Number of Participant's With the Indicated Global Preference for Infusion (Left Versus Right Thigh)

    Participants blinded to the type of infusion were asked to state their preference for the left or right infusion following all infusion day (Day 1) activities and assessments. The preference for the left or right infusion indicated which infusion was preferred: NS or LR.

    Measured: End of infusion (Day 1)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing recombinant human hyaluronidase in people with Healthy, run by Halozyme Therapeutics at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 May 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Participant's Assessment of Discomfort at the Infusion Site on a Visual Analog Scale (VAS) (time frame: Approximate times which ranged from zero minutes at baseline to maximal post-infusion of 240 minutes on Day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Oct 2018; AzTrials last refreshed its copy on 6 Nov 2026.
