Brief Summary:
The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), and antidrug antibody (ADA) response for MEDI8897 in healthy preterm infants who are between 29 and 35 weeks gestational age and entering their first RSV season.

Condition or disease Intervention/treatment Phase
Respiratory Syncytial Virus Infections Drug: MEDI8897 Drug: Placebo Phase 2

Detailed Description:
This pivotal Phase 2b study will determine if MEDI8897 will be efficacious in reducing medically attended RSV-confirmed lower respiratory tract infections (LRTI) in healthy preterm infants entering their first RSV season. The population to be enrolled is healthy preterm infants born between 29 weeks 0 days and 34 weeks 6 days gestational age (GA) who would not receive RSV prophylaxis. A total of 1500 infants will be randomized 2:1 to receive either MEDI8897 or placebo. Subjects will be followed for 360 days after dosing. Enrollment is planned at approximately 197 sites across the USA, Canada, Europe, and the Southern Hemisphere.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 1453 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Phase 2b Randomized, Double-Blind, Placebo-controlled Study to Evaluate the Safety and Efficacy of MEDI8897, a Monoclonal Antibody With an Extended Half-life Against Respiratory Syncytial Virus, in Healthy Preterm Infants
Actual Study Start Date : November 3, 2016
Estimated Primary Completion Date : December 3, 2018
Estimated Study Completion Date : December 3, 2018

Primary Outcome Measures :
  1. Incidence of medically attended LRTI due to RT-PCR confirmed RSV [ Time Frame: 150 days post dose ]
    The incidence of RSV LRTI (inpatient and outpatient) 150 days post dose will be based on RSV test results (performed centrally via RT-PCR) and objective clinical LRTI criteria and will be summarized by treatment group.


Secondary Outcome Measures :
  1. Incidence of hospitalization due to Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) confirmed RSV [ Time Frame: 150 days post dose ]
    The incidence of RSV hospitalization 150 days post dose will be summarized by treatment group.

  2. Safety and tolerability as assessed by the occurrence of all treatment emergent adverse events (TEAEs) and treatment emergent serious adverse events (TESAE) [ Time Frame: 360 days post dose ]

    Safety of MEDI8897 will primarily be assessed and measured by the occurrence of all treatment-emergent AEs and SAEs.

    Other safety assessments will include the occurence of Adverse Event of Special Interest (AESIs) and New Onset Chronic Diseases (NOCDs).


  3. Single-dose serum concentrations of MEDI8897 [ Time Frame: 360 days post dose ]
    MEDI8897 serum concentration data will be tabulated by treatment group along with descriptive statistics. Terminal-phase half-life (t1/2) will be estimated using non-compartmental analysis, if data permit.

  4. Incidence of anti-drug antibody (ADA) to MEDI8897 in serum [ Time Frame: 360 days post dose ]
    The incidence of ADA to MEDI8897 will be assessed and summarized by number and percentage of subjects that are ADA positive by treatment group.
