About this study

Official title: Multicenter Safety Evaluation of Human Rabies Immune Globulin 300 IU/mL in Children

This observational study will be conducted across the Houston Methodist system, including all hospital-based and freestanding emergency departments (ED), and up to 4 additional sites in the United States. The safety of human rabies immune globulin (HRIG) 300 IU/mL product (HyperRAB®) in pediatric patients has not been fully established. The purpose of this study is to evaluate the safety of HRIG 300 IU/mL when given to pediatric patients per standard of care for rabies postexposure prophylaxis (PEP) in the ED.

Read the detailed description

BACKGROUND: Rabies PEP consists of thorough wound cleansing, administration of HRIG 20 IU/kg body weight, and 4 to 5 doses of rabies vaccine. The safety of HRIG 300 IU/mL has been confirmed only for adult patients. Although the safety of HRIG 300 IU/mL in the pediatric population has not been fully established, there is no age limit on the FDA approved indication for HRIG 300 IU/mL, and it is routinely administered to pediatric patients as standard of care in the United States.

STUDY DESIGN: This observational, multicenter, prospective study will collect information on safety events that occur up to 30 days after standard of care administration of HRIG 300 IU/mL among pediatric patients (age ≤17 years) at up to 5 study sites in the United States. Safety data will be collected using surveys and chart review of the health record. All participants will receive HRIG 300 IU/mL per standard of care prior to joining this study. The day of HRIG 300 IU/mL administration will be defined as day 0. The study will conduct Survey 1 on day 2 and Survey 2 on day 10 to collect information on adverse events (AEs). Investigators will review the electronic health record on day 30 to collect additional information on AEs. If a serious adverse event is detected during Survey 1, Survey 2, or the 30-day chart review and is not previously documented as being resolved or stabilized the study will conduct Survey 3 on day 30.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Human rabies immune globulin 300 IU/mLBiological

    All participants in this single-cohort observational study will receive human rabies immune globulin 300 IU/mL at a dose of 20 IU/kg per standard of care.

What is being measured

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

  1. Incidence of local and systemic adverse events (AEs) within 2 days of HRIG 300 IU/mL administration

    Proportion of patients with 1 or more AEs deemed as possibly/definitely related to HRIG 300 IU/mL administration

    Measured: Within 2 days of HRIG 300 IU/mL administration

Secondary outcomes (4)
  1. Cumulative incidence of all local and systemic AEs within 10 days of HRIG 300 IU/mL administration

    Proportion of patients with 1 or more AEs deemed as possibly/definitely related to HRIG 300 IU/mL administration

    Measured: Within 10 days of HRIG 300 IU/mL administration

  2. Cumulative incidence of all local and systemic AEs within 30 days of HRIG 300 IU/mL administration

    Proportion of patients with 1 or more AEs deemed as possibly/definitely related to HRIG 300 IU/mL administration

    Measured: Within 30 days of HRIG 300 IU/mL administration

  3. Cumulative incidence of all local and systemic serious adverse events (SAEs) within 30 days of HRIG 300 IU/mL administration

    Proportion of patients with 1 or more SAE deemed as possibly/definitely related to HRIG 300 IU/mL administration. An AE is considered "serious" if any of the following outcomes occur:

    • Death
    • Life-threatening AE (life-threatening in the definition of "serious" refers to an event in which the participant was at risk of death at the time of the event; it does not refer to an event which hypothetically might have caused death if it were more severe)
    • In-patient hospitalization or prolongation of existing hospitalization
    • A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions
    • An important medical event (refers to events which may not be immediately life-threatening, or result in death, or hospitalization, but from medical and scientific judgment, may jeopardize the participant or/and may require medical or surgical intervention to prevent one of the other outcomes listed above).

    Measured: Within 30 days of HRIG 300 IU/mL administration

  4. Type and severity of individual local and systemic AEs detected within 30 days of HRIG 300 IU/mL administration

    Proportions of AEs that are local vs systemic and proportions of AEs that are mild, moderate, or severe among AEs deemed as possibly/definitely related to HRIG 300 IU/mL administration

    Measured: Within 30 days of HRIG 300 IU/mL administration

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?

Incidence of local and systemic adverse events (AEs) within 2 days of HRIG 300 IU/mL administration (time frame: Within 2 days of HRIG 300 IU/mL administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05382650, which also lists 3 linked publications.

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.
