Ages Eligible for Study:   18 Years to 45 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Age 18 through 45 years at the time of study entry;
  • Weight ≤ 90 kg;
  • Healthy by medical history and physical examination;
  • Normotensive (systolic blood pressure [BP] < 150 mmHg and diastolic BP <90 mmHg);
  • Normal electrocardiogram (ECG) at screening (must occur within 21 days before entry into the study);
  • Normal spirometry at screening (must occur within 21 days before entry into the study). Normal spirometry is defined as FEV1 (forced expiratory volume in 1 second) and FVC (forced vital capacity) ≥ 80% predicted and an FEV1/FVC > 70%.
  • Written informed consent obtained from the subject;
  • Sexually active females, unless surgically sterile, must have used an effective method of avoiding pregnancy (including oral or implanted contraceptives, intrauterine device, female condom with spermicide, diaphragm with spermicide, cervical cap, abstinence, use of a condom with spermicide by the sexual partner or sterile sexual partner) for 14 days prior to study drug dosing, must agree to continue using such precautions for 1 year after administration of study drug, and must have a negative serum pregnancy test within 3 days prior to study drug dosing and a negative urine pregnancy test on the day of study drug administration; and
  • Ability to complete follow-up period of 240 days as required by the protocol.

Exclusion Criteria:

  • Acute illness at study entry;
  • Fever ≥ 99.5°F at study entry;
  • Any drug therapy within 7 days prior to Study Day 0 (except contraceptives);
  • Blood donation in excess of 400 mL within 6 months prior to study entry;
  • Receipt of immunoglobulin or blood products within 60 days prior to study entry;
  • Receipt of any investigational drug therapy or standard vaccine within 120 days prior to study drug dosing through 240 days after study drug dosing;
  • Previous receipt of palivizumab or motavizumab; History of immunodeficiency;
  • History of allergic disease or reactions likely to be exacerbated by any component of either study drug;
  • Previous medical history or evidence of an intercurrent illness that may compromise the safety of the subject in the study;
  • Evidence of any systemic disease on physical examination;
  • Evidence of infection (ie, positive laboratory test result) with hepatitis A, B, or C virus or human immunodeficiency virus-1 (HIV-1);
  • At screening (must be within 21 days before entry into the study) any of the following: hemoglobin < 12.0 gm/dL, white blood cell count (WBC) < 4,000/mm3, platelet count < 120,000/mm3 (or laboratory normal values); aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), serum creatinine > upper limit of normal (ULN); other abnormal laboratory values in the screening panel which, in the opinion of the principal investigator, are judged to be clinically significant; other abnormal laboratory values in the screening panel which, in the opinion of the principal investigator, are judged to potentially confound analysis of study results;
  • Pregnancy, or nursing mother;
  • History of alcohol or drug abuse within the past 2 years; or
  • History of asthma, seasonal allergies, or exercise-induced wheezing.
