Summary
This study will be a double-blind, randomized, placebo-controlled study of a single dose (20mg) of Influenza Antiviral DAS181-F04 for 3 days. The group of nine subjects will be randomly assigned to DAS181 or placebo at 2:1 ratios. Subjects will be admitted to the inpatient clinic at a minimum of the night prior to first dose. The subjects will stay in the inpatient clinic for the duration of dosing and one day after dosing, they will be required to come back for follow-up visits on study days 4, 6, 9, 16 (+/-1 day), 32 (+/-3 days), and 90 (+/-10 days). The safety parameters will include abnormal laboratory values, adverse events and clinical observations.

(PI) or sub-investigator as determined by vital signs, medical history, and a physical
exam. -Subjects must be able to verbalize understanding of the consent form, provide
written informed consent and verbalize willingness to complete study procedures. -Be 18 to
45 years of age (inclusive), at the time of screening. -Subjects must have a Body Mass

indicated. -No history of smoking in the past six months, regardless of clinical relevance.
-Electrocardiogram (ECG) with no clinically significant abnormalities recorded at screening
visit: PR interval within 120 and 200ms, QRS interval < 120ms, and confirmed QTc interval
mmHg) and heart rate between 45 and 100 beats per minute. -Chest X-ray shows no clinically
significant abnormalities. -Forced expiratory volume in 1 second (FEV1) will be greater
than 80% predicted; note: only one baseline value for FEV1 can be used to support inclusion
criterion. -Negative Human Immunodeficiency Virus (HIV), HBSAg, and Hepatitis C Virus (HCV)
antibody screening tests. -Negative screening tests for: marijuana, cocaine metabolite,
amphetamines, opiates, PCP, barbiturates, benzodiazepines, and ethanol. -Subjects with the
following laboratory criteria within provided range (see Appendix B): --Hemoglobin --White
blood cell (WBC) and platelet count --Alkaline phosphatase (ALKP), total bilirubin, alanine
aminotransferase (ALT), --Serum glucose; note: if a non-fasting glucose is performed and is
abnormal, a fasting glucose measurement may be obtained in its place; if this is within the
provided range, then subject may be enrolled. --Serum creatinine --Activated partial
thromboplastin time (APTT) and fibrinogen -Urine glucose and blood tested by dipstick
urinalysis are negative. Urine protein tested by dipstick is negative or trace.
Menstruating females failing inclusion due to positive urine dipstick blood may be retested
following cessation of menses. -Female subjects must be post-menopausal (one year or
greater without menses), surgically incapable of childbearing, or agreeable to practicing
abstinence or utilizing two effective methods of birth control during the study period and
for 12 weeks after study product administration. Acceptable methods may include:

medically accepted form of contraception from time of enrollment to 12 weeks after study
product administration. -Agrees not to drink alcohol or participate in strenuous physical
activity or exercise from 24 hours prior to Day -1 through the Day 6 follow-up visit.

approved by the site PI or sub-investigator. -Existence of any surgical, medical or
laboratory condition that, in the judgment of the site PI or sub-investigator, might
interfere with the safety, distribution, metabolism, or excretion of the drug. -Subjects

rhinitis, chronic obstructive pulmonary disease (COPD), cystic fibrosis, emphysema, or
anaphylaxis) requiring acute or chronic medication, as determined by the investigator
through medical history evaluation and physical examination. -Subjects who have experienced
