Brief Summary:
  • The purpose of this study is to describe the effect of a single (IM) dose of motavizumab in the upper respiratory tract in children who present with RSV illness but who do not require hospitalization at the time of presentation and
  • Describe the effect of a single 30 mg/kg IM dose of motavizumab in decreasing the need for hospitalization due to worsening RSV illness in children who receive outpatient treatment
  • Describe the effect of a single 30 mg/kg IM dose of motavizumab on subsequent respiratory status as measured by the Respiratory Assessment Change Score (RACS) and change in oxygen saturation
  • For children who require hospitalization, describe the effect of motavizumab on severity of RSV illness during hospitalization [i.e., RACS, oxygen saturation, heart rate, use of supplemental oxygen, mechanical ventilation, and duration of intensive care unit (ICU) stay]
  • Describe the effect of a single 30 mg/kg IM dose of motavizumab on duration of symptoms of RSV illness (fever, coryza, cough, and parental opinion of return to normal health and activity)
  • Describe the nasal concentration of motavizumab following a single 30mg/kg dose
  • Describe the serum pharmacokinetics and immunogenicity of a single 30 mg/kg IM dose of motavizumab
  • Describe the effect of motavizumab on markers of inflammation as measured by gene microarray and cytokine levels
  • Evaluate the safety and tolerability of a single 30 mg/kg IM dose of motavizumab in the outpatient treatment of children with RSV
  • Describe the progression and severity of lower respiratory infection (LRI)

Condition or disease Intervention/treatment Phase
Healthy Biological: MEDI-524 Other: Placebo Phase 2

Detailed Description:
This is a Phase 2, randomized, double-blind, placebo-controlled, multicenter study to determine the effect of a single 30 mg/kg IM dose of motavizumab on viral load and motavizumab levels in the upper respiratory tract of children who present with RSV illness but who do not require hospitalization. Using 1:1 randomization, 30 mg/kg motavizumab or placebo will be administered as soon as possible after a child's diagnosis of RSV and his/her eligibility for the study has been confirmed.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate a Single Intramuscular Dose of Motavizumab (MEDI-524), a Humanized Enhanced Potency Monoclonal Antibody Against Respiratory Syncytial Virus (RSV), for the Outpatient Treatment of Children With RSV Illness
Study Start Date : March 2007
Actual Primary Completion Date : May 2008
Actual Study Completion Date : July 2008

Arm Intervention/treatment
Experimental: 1
Biological: MEDI-524
30 mg/kg of MEDI-524
Other Name: Motivizumab
Placebo Comparator: 2
Other: Placebo
30 mg/kg of Placebo

Primary Outcome Measures :
  1. The specific measure will be to determine viral load in the upper respiratory tract in children with RSV infection by comparing mean RT-PCR val. over time between treatment groups [ Time Frame: Days, 0,2,8-29 (if hospitalized), 30 & 90 ]

Secondary Outcome Measures :
  1. For children with RSV illness; a) the change in RACS from baseline at randomization; b) the change in oxygen saturation over time [ Time Frame: Through Day 30 ]
  2. Percentage of children who have progression of RSV illness that requires subsequent hospitalization. [ Time Frame: Through Day 30 ]
