• Able and willing to give written informed consent.
• Has the ability to complete the follow-up period as required by the protocol.
• Subjects must agree to abstain from alcohol intake 24 hours before administration of study drug, during the inpatient period(s) of the study and 24 hours prior to all other outpatient clinic visits.
• Subjects must agree to not use OTC medications (including aspirin, decongestants, antihistamines and other NSAIDs), and herbal medication (including, but not limited to, herbal tea, St. John's Wort), within 14 days prior to study drug administration through the final follow-up visit, unless approved by the investigator and medical monitor. Occasional use of acetaminophen/paracetamol at recommended doses (≤ 1 gram/6 hours and ≤ 4 grams/day) and continued pre-existing use of vitamins or multivitamins at recommended doses is allowed.
• Female subjects must:
• Be surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), or
• If heterosexually active, use two effective methods of birth control, including hormonal prescription oral contraceptives, contraceptive injections, contraceptive patch, contraceptive ring, intrauterine device, barrier method (e.g. condoms, diaphragm, or cervical cap), or spermicidal foam, cream, or gel), or
• Confirm male partner sterilization, or
• Not be heterosexually active Note: women who are not heterosexually active at screening must agree to utilize two effective methods of birth control if they become heterosexually active during their participation in the study.
• Women must agree to continue using these methods of contraception throughout the study.
• Females must have a negative urine pregnancy test at both screening and baseline.
• If a man who is able to father a child and sexually active with a female of childbearing potential, he must agree to use a double barrier method of birth control (e.g. condom with spermicidal foam, cream, or gel) and to not donate sperm during the study.
• Subjects must agree to avoid strenuous exercise (e.g. long distance running > 5km/day, weight lifting, or any physical activity to which the subject is not accustomed) while confined to the Clinical Unit and for at least 72 hours prior to study drug administration and follow up visits.

• Temperature >99.5 °F (37.5 °C) at randomization.
• Presence of a significant infection or known inflammatory process during screening or at the time of randomization.
• Presence of acute gastrointestinal symptoms during screening or at the time of randomization (e.g. nausea, vomiting, diarrhea, or heartburn).

• Chronic (longer than 14 days) administration of immunosuppressants or other immune modifying drugs within 6 months before administration of the investigational product; oral corticosteroids in dosages of < 0.5 mg/kg/day prednisolone or equivalent and inhaled/nasally/topically administered corticosteroids are permitted.
• Antibiotic therapy within 7 days before Study Day 1.
• History and/or presence of any clinically significant disease or disorder such as cardiovascular, pulmonary, renal, hepatic, neurological, gastrointestinal and psychiatric/mental disease/disorders, which, in the opinion of the Principal Investigator may either put the subject at risk because of participation in the study, influence the results of the study or the subject's ability to participate in the study.
• Previous medical history that may compromise the safety of the subject in the study.
• Positive serology for the human immunodeficiency virus (HIV) 1 or 2 antibody, hepatitis C virus antibody or hepatitis B surface antigen.
• History of a previous severe allergic reaction with generalized urticaria, angioedema, or anaphylaxis.

• A history of alcohol or drug abuse within the past 2 years as according to DSM IV.
• Positive urine test for illicit drugs (opiates, cocaine, amphetamines) during screening and admission (Day -1).
• Subjects who report current tobacco use of more than 10 cigarettes or 2 cigars per day at screening or anticipate use exceeding this amount at any time during the study.
• Receipt of any other investigational product within 1 month or 5 half-lives (whichever is longer) before administration of the study investigational product.
• Participation in any clinical study involving receipt of investigational product, blood or blood products, or donation of blood throughout the duration of the study.
