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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • A positive influenza Rapid Antigen Test (RAT) and/or a FDA-approved PCR test and at least one clinical sign or symptom consistent with acute influenza infection as listed below OR
  • Clinical signs and symptoms consistent with acute influenza infection consisting of an oral temperature ≥ 100°F (37.8°C) with at least one respiratory symptom of at least moderate severity (cough or rhinitis) and at least one constitutional symptom of at least moderate severity (myalgia [aches and pains], headache, feverishness, or fatigue)
  • Influenza symptom onset < 48 hours. However, due to historically delayed presentation for medical care in the adult population, approximately 20% of the elderly population may be enrolled with symptoms starting > 48-hours but ≤ 72-hours

Exclusion Criteria:

  • Women who plan to breast-feed for the first 48 hours after study drug administration
  • Subjects requiring hospital admission to treat medical condition(s) which could represent complications of influenza.
  • Recent worsening of any chronic medical condition consistent with complications of influenza
  • Current evidence of a bacterial infection requiring antibiotic treatment

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
Safety and Tolerability, as Measured by the Number of Adverse Events.
Time Frame: 14 days
Safety was evaluated through assessment of Adverse Events (AEs).
14 days

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
Plasma Exposure of IV Peramivir as Measured by Drug Concentrations up to 3 Hours Post Infusion
Time Frame: up to 3 hours post peramivir infusion
Up to 3 plasma samples will be drawn, where possible: immediately following infusion, 30 mins to 1 hr post-infusion & 1 to 3 hrs post-infusion. Maximum concentration (Cmax), area under the concentration vs. time curve (AUC) from time 0 to 1 hour (AUC0-1), AUC from time 0 to 1.5 hours (AUC0-1.5), and AUC from time 0 to the last measurable time point (AUC0-last) were calculated in Phoenix® WinNonlin® v6.4. No summary statistics were reported due to the variation in the infusion time and sampling times.
up to 3 hours post peramivir infusion
Time to Resolution of Fever
Time Frame: 14 days
Time for fever resolution based on subject diary record of temperature recorded twice daily. A subject had resolution of fever if he/she had an oral temperature < 37.4°C/99.4°F oral and no antipyretic medications were taken for at least 12 hours. The time to resolution of fever was estimated for each age group and overall using the Kaplan-Meier method with temperature and symptom relief medication information obtained from the Subject Diary data. Subjects who did not have resolution of fever were censored at the time of their last non-missing post-baseline temperature assessment.
14 days
Time to Resolution of Influenza Symptoms
Time Frame: 14 days
Subjects were asked to provide an assessment of 7 influenza symptoms (cough, sore throat, nasal congestion, myalgia [aches and pains], headache, feverishness, and fatigue) on a 4-point severity scale (0, absent; 1, mild; 2, moderate; 3, severe) beginning at Screening then twice daily beginning on Day 1 through to Day 13, and prior to the subject's clinic visit on Day 14. Once all symptoms were scored a 0 or 1 for at least 48 hours, recordings were discontinued. The time to alleviation of symptoms, defined as the time from initiation of study drug until the start of the 21.5-hour period (24 hours less 10%), where all symptoms of influenza were recorded as none (0) or mild (1), was estimated overall and for each age group using the Kaplan-Meier method.
14 days
Changes in Influenza Virus Titer in Nasopharyngeal Samples in Response to Treatment.
Time Frame: Change from baseline assessed on days 3, 7 and 14.
Change in influenza viral titers was defined as the time-weighted change from Baseline in log_10 tissue culture infective dose_50 (TCID50/mL) and was summarized for each treatment group.
Change from baseline assessed on days 3, 7 and 14.
Time to Reduction in Viral Shedding
Time Frame: 14 days
Assessment of viral shedding in bilateral, mid-nasal swab specimens taken at baseline and then on Day 3, 7 and 14.
14 days
Incidence of Influenza-related Complications
Time Frame: 14 days
Study personnel evaluated the subject at Screening and Days 3, 7, and 14 for the presence of clinical signs and/or symptoms of the following influenza-related complications: Sinusitis, Otitis media, Bronchitis & Pneumonia. Note that subjects with clinical signs and/or symptoms consistent with bacterial infections, including otitis media, bronchitis, sinusitis, and/or pneumonia at Screening, were not eligible for enrollment in this study. If an influenza-related complication was suspected, then a targeted physical examination was to be conducted to confirm the presence or absence of the influenza-related complication.
14 days
Time to Return to Usual Activities
Time Frame: 14 days
The ability to perform usual daily activities was assessed on a VAS (Visual Analogue Scale), where 0 indicates "unable to perform usual activities at all" and 10 indicates "able to perform usual activities.". The time to return to usual activities was the number of days from initiation of study drug until the subject recorded a rating of 10 (able to perform all usual activities fully) on the VAS; this was estimated for each age group and overall using the Kaplan-Meier method.
14 days
