Information provided by (Responsible Party):
Trial Management Group Inc.
  Purpose
This study has been designed to determine if subjects treated with oseltamivir in addition to standard of care treatment for influenza demonstrate a greater improvement in attention / working memory / processing speed / mood as compared to subjects receiving standard of care alone. The cognitive tests employed are objective measures developed and administered online by HeadMinder Inc.

Condition Intervention Phase

Primary Outcome Measures:
  • Change in Attention Assessment [ Time Frame: Change from baseline at Day 4 ]

    Attention assessed using simple reaction time measured in milliseconds. Simple reaction time calculated as the mean of the following 2 sub-tests:

    • Reaction Time Subtest
    • Cued Reaction Time Subtest

    The lower the value, the better the attention.



Secondary Outcome Measures:
  • Change in Working Memory Assessment [ Time Frame: Change from baseline at Day 4 ]

    Working memory assessed with the Dot Memory Test.

    The higher the value, the better the working memory.


  • Change in Processing Speed Assessment [ Time Frame: Change from baseline at Day 4 ]

    Processing speed assessed with the animal number decoding subtest

    The lower the value, the better the processing speed



Other Outcome Measures:
  • Change in Mood Assessment [ Time Frame: Change from baseline at Day 4 ]

    Mood was assessed using the Bond-Lader 10 cm (100 mm) visual analogue scales for mood (16 scales in total); factored for alertness (mean of 9 scales), calmness (mean of 2 scales) and contentment (mean of 5 scales).

    The range in score for each scale and for each factor (alertness, calmness and contentment) was 0 - 100 mm.

    Each scale was anchored such that the lower the value, the better the mood.

Standard of care for influenza

Detailed Description:

Primary Objective:

To determine if subjects treated with oseltamivir in addition to standard of care treatment for influenza demonstrate a greater improvement in attention as compared to subjects receiving standard of care alone.

Secondary Objectives:

To determine if subjects treated with oseltamivir in addition to standard of care treatment for influenza demonstrate a greater improvement in working memory and processing speed as compared to subjects receiving standard of care alone.

Supportive Objectives:

  1. To determine if subjects treated with oseltamivir in addition to standard of care treatment for influenza demonstrate a greater improvement in self-rated alertness as compared to subjects receiving standard of care alone.
  2. To determine if subjects treated with oseltamivir in addition to standard of care treatment for influenza demonstrate a greater improvement in self-rated calmness and contentment as compared to subjects receiving standard of care alone.
  3. To determine if there is a correlation between the rate of improvement in symptom scores and the rate of change in attention and working memory.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Adult men and women, 18 - 65 years of age (inclusive)
  2. Indicative symptoms/signs of uncomplicated acute illness due to influenza infection (A or B strains) that started within a maximum of 2 days prior to Visit 1 as per the Tamiflu® Canadian product label. Signs and symptoms may include the following:

    • Fever
    • Respiratory symptoms (cough, coryza, sore throat, rhinitis)
    • Constitutional symptoms (headache, malaise, myalgia, sweats and/or chills, fatigue)
  3. Positive rapid antigen test for influenza (A or B strains) at Visit 1
  4. Negative urine pregnancy test at Visit 1 for women of childbearing potential; women of childbearing potential who are sexually active must agree to use a suitable form of contraception during the study. Acceptable birth control measures include: hysterectomy, birth control pills, tubal ligation, intrauterine device, hormonal injections and implants, double barrier methods (such as a condom with a diaphragm or a condom with spermicide), and abstinence. Oral contraceptives must be in stable use for 2 or more cycles prior to screening. Intrauterine device (IUD) must be in use at least 30 days prior to study drug administration. Barrier methods must be in use at least 14 days prior to study drug administration.
  5. Subjects must:

    • have daily access to a computer at home with: internet access (preferably high-speed for optimal performance but dial-up can be used as well); Microsoft operating system; Internet Explorer browser capability and an e-mail account. A Macintosh (Mac) computer cannot be used.
    • be capable of and willing to complete the required online assessments in English according to the protocol schedule
    • be willing to abstain from the use of an antiviral medication if they are randomised to the standard of care treatment arm
    • have provided written informed consent prior to the initiation of any study procedures

Exclusion Criteria:

  1. More than 2 days since the onset of influenza symptoms
  2. Subjects who, in the Investigator's judgment, require treatment with an antiviral medication as per the Canadian "Clinical Recommendations for Patients Presenting with Respiratory Symptoms During the 2009 - 2010 Influenza Season" (see Appendix D)
  3. Clinical suspicion of infection with a respiratory virus other than influenza
  4. Any medical condition that is sufficiently severe or unstable such that the subject is considered to be at imminent risk of requiring hospitalisation
  5. History of conditions that may potentially affect cognitive function during the study, such as underlying neurologic conditions, depression or depressive disorders (unless the condition and treatment have been stable for 3 months), seasonal affective disorder (SAD), or any other cognitive impairment or dementia
  6. Intermittent use of sedative-hypnotics; subjects who have been taking a fixed dose of a sedative-hypnotic every day for a period of at least 30 days may be included provided that they continue the same regimen throughout the study.
  7. Intermittent or chronic use of psychiatric medications (with the exception of antidepressants that have been stable for 3 months) or anti-epileptic drugs
  8. Nursing home residents
  9. Known allergy to oseltamivir phosphate or any of the inactive ingredients of Tamiflu®
  10. Women who are pregnant, or planning to become pregnant, or who are lactating
  11. Current alcohol or drug abuse or substance dependence
  12. Participation in another clinical trial with an investigational drug within the last 30 days
  13. Patients vaccinated for influenza within 6 months of study enrollment
  14. In the Investigator's judgment, the subject will not be able to adhere to the protocol requirements or is not suitable for study participation for any reason
