Safety, Tolerability, and Pharmacokinetics of SAB-301 in Healthy Adults
Condition: Middle East Respiratory Syndrome Coronavirus
MeSH terms: Coronavirus Infections
Intervention: SAB-301; Normal (9%) Saline
Intervention description: SAB-301 is a purified human immune globulin G (hIgG) polyclonal antibody designed to specifically bind to the MERS-CoV spike (S) protein, a component of the virion membrane that is responsible for binding of the virus to the host cell. The hIgG is purified from the plasma of immunized transchromosomic (Tc) bovines that were immunized with a recombinant spike protein produced in insect cells. SAB-301 is purified hIgG in a sterile liquid formulated in 10 mM glutamic acid monosodium salt, 262 mM D-sorbitol, 0.05 mg/mL Tween 80, pH 5.5. The drug product will be administered intravenously and will be diluted in saline per the clinical protocol.; Normal (0.9%) saline in approximately the same volume as each cohort in the experimental drug arm.

Summary:

      Background:

      Middle East Respiratory Syndrome (MERS) is a newly discovered contagious and sometimes fatal
      respiratory virus. People often get MERS through close contact with an infected person.
      Scientists are worried that MERS may spread and cause more infections. There are no vaccines
      or treatments for MERS right now. Researchers think a new therapy called SAB-301 may be able
      to help. Antibodies are proteins the body makes to attack viruses. SAB-301 is made of
      antibodies made in cows to fight MERS. The antibodies are collected from plasma, the liquid
      part of cow blood.

      Objective:

      To evaluate the safety and tolerability of SAB-301 in healthy adults.

      Eligibility:

      Healthy people ages 18 60 who:

      Do not have chronic medical problems

      Do not take any medications (exceptions are acetaminophen, ibuprofen, vitamins, seasonal
      allergy meds and oral contraception)

      Do not have allergies to beef products

      Agree to use two forms of contraception while on study (both men and women)

      Design:

      Participants will be screened with:

      Medical history

      Physical examination

      Blood and urine tests

      Participants will have a return visit.

      They will have a physical exam and blood tests.

      They will be randomly assigned to receive either SAB-301 or a placebo which is given by
      infusion

      through an arm vein over 1 3 hours.

      They will be monitored at the clinic for 6 hours after the infusion. They will have
      additional blood draws.

      Participants will have 2-hour visits 1, 3, 7, 21, 42, and 90 days after the infusion. At each
      visit they will be evaluated and have blood and urine tests.
    

Eligibility criteria:

        -  INCLUSION CRITERIA:

               1. Age greater than or equal to 18 years and less than or equal to 60 years

               4. Subjects must agree to:

          -  Not take any prescription or OTC medications with the exception of acetaminophen,
             ibuprofen, vitamins, seasonal allergy medications, and/or contraceptive medications
             for a period 7 days prior to study drug administration (i.e., Day 0)
