DAS181 Single Dose Escalation Study in Healthy Adults

Completed · Phase 1

Conditions studied: Healthy

In brief

This study will evaluate the safety, tolerability, and systemic exposure of an experimental influenza (flu) treatment medication called DAS181. DAS181 is a dry powder that is administered via oral inhalation using a special device. Study participants will include healthy non-smoking males and females, ages 18-65. They will be given either DAS181 or placebo. Participants will remain in the clinic overnight to be watched for health changes for 24 hours after receiving the medication. Study procedures include: physical exams, chest x-rays, ECGs, lung function tests, collection of blood and urine samples, and throat swabs. Follow-up visits will occur on study days 2, 7, 14 and 30.

• No recent history of smoking in the past two years regardless of clinical relevance.
• No history of alcoholism or alcohol abuse regardless of clinical relevance.
• Electrocardiogram (ECG) with no clinically significant abnormalities recorded at screening visit: PR interval within 120 and 200 ms, QRS interval < 120 ms, and QTc interval ≤ 440 ms.
• Blood pressure within normal limits (systolic 90-140mmHg; diastolic 50-90 mmHg) and heart rate between 45 and 100 beats per minute.
• Chest X-ray and FEV1 results show no clinically significant abnormalities.
• Negative HIV, HBV, and HCV screening tests.

• Female subjects must be post-menopausal (one year or greater without menses), surgically incapable of childbearing, or practicing an acceptable method of birth control. Acceptable methods may include intrauterine device, spermicide and barrier, abstinence and hormonal contraception. A female subject must agree to practice an acceptable method of birth control during study period and for 12 weeks after study terminates. She must have had a negative serum pregnancy test during the screening visit and a negative urine pregnancy test on the day of treatment prior to study drug dosing.
