Safety & Pharmacokinetics Study of Inhaled Laninamivir Octanoate TwinCaps® Dry Powder Inhaler in Children With Influenza
- Conditions
- Influenza
- Interventions
- Registration Number
- NCT02014649
- Lead Sponsor
- Biota Scientific Management Pty Ltd
- Brief Summary
This Phase 1/2 protocol is designed to collect safety, tolerability and pharmacokinetic data of two doses of Laninamivir Octanoate in children and adolescents. The protocol will also explore virology and efficacy endpoints.
- Detailed Description
Approximately 48 subjects aged 5-17 years inclusive will be randomised into the study.
Subjects with recent onset of presumptive influenza will have influenza A or B infection confirm by Rapid Antigen Test.
The study will be conducted on an outpatient basis. The dose is administered in a single session in the clinic on Day 1. The subject will return to the clinic for assessments and follow up.

- time when the subject first experienced at least one influenza symptom (non-productive cough, sore throat or nasal congestion/runny nose, headache, muscle aches and pain, feeling feverish, or low energy/tired/fatigue)
-
In the Investigator's opinion able to complete the required inhalations of the investigational medicinal product.
- Use of antiviral treatment for influenza (e.g., zanamivir, oseltamivir, peramivir, rimantadine, or amantadine) within 14 days prior to screening
- Received influenza virus vaccine in the previous 3 weeks.
- History or presence of clinically significant pulmonary disease (e.g., chronic obstructive pulmonary disease, cystic fibrosis, or bronchiectasis)
- Current asthma requiring treatment, or history of asthma requiring treatment in the last 5 years, or episode of wheezing in the 12 months prior to randomization.
- History of congestive heart failure with symptoms consistent with New York Heart Association Class III or IV functional status.
- Presence of an immune compromised status due to chronic illness, organ transplantation or use of daily systemic immunosuppressants
- Presence of clinically significant signs of acute respiratory distress during screening.
- Current use of inhaled medications (nasal or oral) or anticipated use of inhaled medications (nasal or oral) at any time during the study.
- Current or a history of acute or chronic renal impairment/disease
- Currently hospitalized or any planned hospitalizations within 1 month following the last dose of IMP.
- Current clinical evidence of otitis, bronchitis, sinusitis, or pneumonia or active bacterial infection at any body site
- Severe infection within 30 days prior to screening which required parenteral antibiotic use or hospitalization.

Group Intervention Description 20mg Laninamivir Octanoate 20 mg laninamivir octanoate Dry Powder plus placebo 40mg Laninamivir Octanoate 40 mg laninamivir octanoate Dry Powder 20mg Laninamivir Octanoate Placebo Dry Powder plus placebo
- Primary Outcome Measures
Name Time Method To Evaluate Time to First Alleviation of a Composite of Influenza Symptoms and Absence of Fever. Subjects are assessed at clinic visits and followed up to 28-days post dose. 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.
- Secondary Outcome Measures
Name Time Method To Evaluate the Pharmacokinetic (PK) Profiles (Concentration) of the Prodrug, Laninamivir Octanoate, and Its Active Metabolite, Laninamivir, Following Administration of a Single Dose (20 or 40 mg) Samples are collected at clinic visits over 5 days. Pharmacokinetic parameters will be calculated and summarized, PK concentration data will add to population models.
