Safety Study of a Monoclonal Antibody to Respiratory Syncytial Virus (RSV) in Children Hospitalized With RSV Infection

10 de setembro de 2021 atualizado por: MedImmune LLC

A Phase 1, Randomized, Placebo-Controlled, Dose-Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Immunogenicity of a Single Intravenous Dose of MEDI-524, a Humanized Enhanced Potency Monoclonal Antibody to Respiratory Syncytial Virus (RSV), in Otherwise Healthy Children Hospitalized With RSV Infection

The purpose of this study is to determine the safety of motavizumab (MEDI-524) following a single intravenous dose in children hospitalized with respiratory syncytial virus (RSV).

Visão geral do estudo

Descrição detalhada

This study was designed as a Phase 1, randomized, double-blind, placebo-controlled, dose-escalation, multicenter clinical study to evaluate the safety, tolerability, serum concentrations, and immunogenicity of a single intravenous dose of motavizumab (MEDI-524) and the effect on the amount of respirtory syncytial virus (RSV) in the respiratory tract (nasopharynx) of otherwise healthy children hospitalized with RSV infection.

Descrição

Inclusion Criteria:

  • Previously healthy
  • Age 24 months and younger at the time of randomization
  • Gestational age of 36 weeks gestation and older
  • Randomization within 24 hours after hospitalization
  • Hospitalized for lower respiratory tract illness (ie, respiratory syncytial virus (RSV) bronchiolitis and/or pneumonia) documented by positive RSV antigen detection or culture in respiratory secretions within 72 hours before randomization

Exclusion Criteria:

  • Already received or would receive ribavirin or other anti-viral treatment for the current episode of RSV infection prior to randomization
  • Required intubation for ventilatory support
  • Any medically significant underlying ongoing chronic illness or organ system dysfunction or other known acute illness, other than RSV infection
  • Known renal impairment, hepatic dysfunction, hematologic abnormalities, seizure or other neurologic disorder or immunodeficiency
  • Requirement for supplemental oxygen at any time prior to the current RSV infection (brief use of oxygen in the immediate postnatal period to treat a transient condition was allowed)
  • Mechanical ventilation at any time prior to the onset of the current RSV infection
  • Congenital heart disease (children with medically or surgically corrected patent ductus arteriosus [PDA], small atrial septal defect [ASD] or ventricular septal defect [VSD] were allowed)
  • Previous reaction to intravneous immunoglobulin (IVIG), blood products, or other foreign proteins
  • Prior use of IVIG, RSV-IGIV (RespiGam), palivizumab (Synagis), or other immunoglobulin products within the past 2 months
  • Currently receiving other investigational agents or have received any other investigational agents within the last 3 months
  • Prior or current participation in any investigational study with a therapeutic agent or vaccine for RSV
