Trial Outcomes & Findings for Safety & Pharmacokinetics Study of Inhaled Laninamivir Octanoate TwinCaps® Dry Powder Inhaler in Children With Influenza (NCT NCT02014649)

NCT ID: NCT02014649

Last Updated: 2025-01-13

Results Overview

For subjects aged 5 through 12 years, the subject or parent/legal guardian completed the Canadian Acute Respiratory Illness and Flu Scale (CARIFS) symptom diary and measured otic body temperature twice a day, in the morning between 6 and 10AM and evening between 6 and 10PM, until the Day 10 visit. Subjects aged 13 through 17 years completed the Influenza Symptom Questionnaire (ISQ) themselves and measured otic body temperature twice a day, in the morning between 6 and 10AM and evening between 6 and 10PM, until the Day 10 visit.
