Oseltamivir Infant Influenza Safety Study

October 13, 2011 updated by: Barbara Rath, Charite University, Berlin, Germany

A Prospective, Observational Safety Study in Children <= 24 Months of Age Receiving Oseltamivir for the Treatment or Prophylaxis of Influenza Infection

In June 2009, the World Health Organization (WHO) declared a global pandemic of influenza A (H1N1). Although little is known about the pandemic influenza strain in children, during previous pandemics and influenza seasons children less than one year of age were shown to be at higher risk of influenza complications than older children. In light of the 2009 H1N1 pandemic situation, the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), and Health Canada issued emergency authorizations for oseltamivir to be used to treat and prevent influenza in infants under 1 year of age. It is anticipated that oseltamivir use in infants will dramatically increase due to the new authorizations for use in this population and high prevalence of H1N1 influenza circulating in the population. Ongoing safety surveillance is critical and this study will provide further data for evaluating the risk/benefit ratio of prescribing oseltamivir to this population in the current milieu of both seasonal and pandemic influenza viruses circulating in the population. The study will also provide useful information on the dose and duration of treatment used in clinical practice and their relationship to adverse events.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study is a prospective, observational, multicenter short-term safety study of the use of oseltamivir (prophylaxis or treatment) in children 24 months of age or younger. An internal comparator group of children diagnosed with influenza and not treated with antiviral medications will be enrolled. The study includes a 30-day follow-up period and will be conducted in multiple sites in multiple countries within the European Union. The study will cover two consecutive influenza seasons: 01 October 2009 - 31 May 2010 and 01 October 2010 - 31 May 2011. Data collection may be interrupted in the interim period between influenza seasons (June 1, 2010 - September 30, 2010), depending on whether the influenza season follows the expected cycle.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 day to 2 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The study will be conducted in multiple sites in multiple countries within the European Union. Initially, five countries (United Kingdom, Austria, Finland, Poland, Germany) are selected for inclusion, but additional countries in Europe, are likely to be added. It is estimated that 3-12 sites per country will be enrolled, with a target of at least 900 patients. If additional countries are added, the number of sites/patients recruited per country will be adjusted accordingly.

Description

Inclusion Criteria:

  • 24 months of age or younger at time of enrollment
  • Diagnosis of influenza A or B (suspected* or confirmed by viral testing) either treated with oseltamivir or with no antivirals OR prescribed oseltamivir for post-exposure influenza prophylaxis
  • Parent/legal guardian willing to provide informed consent and be contacted by telephone as part of follow-up

Exclusion Criteria:

  • Patients will be excluded if treated with an influenza antiviral other than oseltamivir, including amantadine, rimantadine, or zanamivir.

    • Suspected influenza is defined as an acute febrile illness characterized by the presence of fever and 1 or more of the following symptoms: cough, coryza/nasal congestion or sore throat.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Influenza treatment with oseltamivir
Patients 24 months of age and younger initially presenting with confirmed or presumed influenza A or B infection treated with oseltamivir.
Influenza prophylaxis with oseltamivir

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of subjects with Adverse Events
Time Frame: Study Day 7 post-baseline
Information on the number of subjects with AEs will be collected at 7 days post-baseline. AEs include influenza symptoms and associated complications solicited from parent/legal guardian; secondary complications of influenza reported by physician, including otitis media and bacterial infections; and any other non-serious and serious AEs.
Study Day 7 post-baseline
Number of subjects with Adverse Events
Time Frame: Study Day 30 post-baseline
Information on the number of subjects with AEs will be collected at 30 days post-baseline. AEs include influenza symptoms and associated complications solicited from parent/legal guardian; secondary complications of influenza reported by physician, including otitis media and bacterial infections; and any other non-serious and serious AEs.
Study Day 30 post-baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of subjects treated with oseltamivir
Time Frame: Day 30 post baseline
Data on dosage and duration of treatment with oseltamivir in real-world practice are collected. The aim is to examine the relationship of adverse events to the regimen of oseltamivir.
Day 30 post baseline
Number of subjects with drug-resistant virus
Time Frame: Day 30 post-baseline
Data on oseltamivir resistance are collected (as reported only)
Day 30 post-baseline
