Completed · Phase 1 · Has a placebo group

Conditions studied: Influenza

In brief

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.

Actual lower weight limit may be 50 kg, if BMI is in the range 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 </= 440ms. -Blood pressure within normal limits (systolic 86 - 140mmHg; diastolic 50 - 90 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.
