First received: March 7, 2012
Last updated: October 4, 2013
Last verified: October 2013
This is a Phase 1, double-blind, placebo controlled study enrolling 42 healthy adult subjects (18-45yrs) from 1 site. Subjects will be randomized in a 2:3:2 ratio to receive MEDI-557 or placebo. Subjects will receive 1 intravenous dose on Study Day 1. Subjects will be followed for safety from the time of Informed Consent through 360 days post dose.

Condition Intervention Phase
Respiratory Syncytial Virus Drug: Placebo Drug: MEDI-557 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Official Title: A Phase 1, Randomized, Double-Blind, Placebo-controlled Study to Evaluate the Safety and Tolerability of MEDI-557, a Humanized Monoclonal Antibody With an Extended Half-life Against Respiratory Syncytial Virus (RSV), Administered to Healthy Adults

Further study details as provided by MedImmune LLC:

Primary Outcome Measures:
  • Safety and Tolerability [ Time Frame: from time of informed consent through 360 days post dose (approximately 1 year total) ]
    The occurrence of AEs and SAEs

  • Safety and Tolerability [ Time Frame: Pre-dose; every 30 minutes during infusion; up to 24 hours after end of infusion ]
    Vital sign measurements - blood pressure, heart rate, respiratory rate, temperature

  • Safety and Tolerability [ Time Frame: from Day 1 (pre-dose) through 360 days post dose. ]
    Clinical lab measurements - chemistry, hematology; Urinalysis

Secondary Outcome Measures:
  • Pharmacokinetic Assessments - Serum [ Time Frame: 1st dose through 360 days post dose ]
    Maximum serum concentration; Time to maximum serum concentration; Terminal phase elimination half-life; Area under the serum concentration-time curve from time zero to last measurable time point; Area under the serum concentration-time curve from time zero to infinity; Clearance; Volume of distribution

  • Occurrence of anti-MEDI-557 antibody - Serum and Nasal Wash [ Time Frame: 1st dose through 360 days post dose ]
    MEDI-557 concentrations in serum and nasal wash through 360 days post dose

  • Pharmacokinetic Assessments - Nasal Wash [ Time Frame: 1st dose through 360 days post dose ]
    Maximum nasal wash concentration; Time to maximum nasal wash concentration; Area under the nasal wash conentration-time curve from time zero to last measurable time point

  • anti-RSV antibody in Serum and Nasal Wash [ Time Frame: 1st dose through 360 days post dose ]
    To evaluate anti-RSV antibodies (F-specific IgG and neutralizing) in serum and nasal wash.

Detailed Description:
A Phase 1, randomized, double-blind, placebo-controlled study evaluating the safety and tolerability of MEDI-557 administered IV to healthy adult subjects (18-45yrs). A maximum of 42 subjects from 1 site will be enrolled in a 2:3:2 ratio (12 placebo, 18 MEDI-557 low-dose, 12 MEDI-557 high-dose) to allow for greater data collection in the low-dose group. Subjects are evaluated for safety from time of Informed Consent through Study Day 360 post dose.
