This study (MI-CP117) is a Phase 3, randomized, double-blind, placebo-controlled trial designed to determine if MEDI-524 compared to placebo will result in clinical efficacy in the reduction of RSV hospitalization in otherwise healthy Native American Indian Infants in the Southwestern United States during their first RSV season.

Condition Intervention Phase
Biological: MEDI-524
Other: Placebo
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 3 Study of MEDI-524 (Motavizumab) for the Prevention of RSV Disease Among Native American Infants in the Southwestern United States

Further study details as provided by MedImmune LLC:

Primary Outcome Measures:
  • The incidence of RSV hospitalization from Study Day 0 through Study Day 150 of the 1st RSV season will be the primary endpoint. [ Time Frame: Through Day 150 ]

Secondary Outcome Measures:
  • Safety and tolerability of MEDI-524 will be assessed primarily by summarizing adverse events and serious adverse events occurring through Study Day 150. [ Time Frame: Through Day 150 ]

Enrollment: 2127
Study Start Date: November 2004
Study Completion Date: March 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: 2
Other: Placebo
15 mg/kg placebo administered intramuscularly every 30 days for a maximum of 5 injections during the RSV season.
Active Comparator: 1
Biological: MEDI-524
15 mg/kg motavizumab administered intramuscularly every 30 days for a maximum of 5 injections during the RSV season


Ages Eligible for Study:   1 Month to 6 Months   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • 6 months of age or younger at randomization (child must be randomized on or before their 6-month birthday)

  • Written informed consent obtained from the patient's parent(s) or legal guardian

Exclusion Criteria:

  • Gestational age less than or equal to 35 weeks
  • Chronic lung disease of prematurity
  • A bleeding diathesis that would preclude IM injections
  • Hospitalization at the time of randomization (unless discharge is anticipated within 10 days)
  • Active RSV infection (a child with signs/symptoms of respiratory infection must have negative RSV testing) or known prior history of RSV infection
  • A documented wheezing episode before enrollment
  • Known renal impairment
  • Known hepatic dysfunction
  • Clinically significant congenital anomaly of the respiratory tract
  • Chronic seizure or evolving or unstable neurologic disorder
  • Congenital heart disease (children with uncomplicated CHD [e.g., PDA, small septal defect] and children with complicated CHD who are currently anatomically and hemodynamically)
  • Known immunodeficiency
  • Mother with HIV infection (unless the child has been proven to be not infected)
  • Known allergy to Ig products
  • Receipt of palivizumab, RSV-IGIV, or other RSV-specific monoclonal antibody, or any other polyclonal antibody (for example, hepatitis B IG, IVIG) within 3 months prior to randomization
  • Anticipated use of palivizumab or IVIG during the study (blood transfusions permitted)
  • Previous receipt of RSV vaccines
  • Participation in other investigational drug product studies
  • Any medical or social condition which, in the opinion of the investigator, would adversely affect monitoring the infant
  • Inability to complete the study follow-up period through up to 5 years of age
