Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

1. Age 13 to 65 years
2. Presence of clinical signs and/or symptoms consistent with acute illness compatible with influenza infection (each of the following is required):

1. oral temperature of =100.4 °F or =38 °C (obtained in office or self-measured within 12 hours prior to screening - if self-measured, subject must also have taken an antipyretic within 4 hours prior to screening) AND
2. at least one of the following respiratory symptoms (cough, sore throat, nasal obstruction) that is considered by the patient to be moderate or severe (greater than mild severity) AND

Current criteria for persons 13-65 years of age who are at risk of influenza complications include (list to be reviewed and updated as required prior to initiation of the study and at least monthly during the study):

1. Persons with asthma or other chronic pulmonary diseases, such as cystic fibrosis in children or chronic obstructive pulmonary disease in adults.
2. Persons with hemodynamically significant cardiac disease.
3. Persons who have immunosuppressive disorders or who are receiving immunosuppressive therapy.
4. HIV-infected persons.
5. Persons with sickle cell anemia or other hemoglobinopathies.

Female patients of child-bearing potential that are sexually active must have a negative baseline pregnancy test and must agree to continue an acceptable method of birth control for the duration of the study and for 1 month post-treatment. A double barrier method, oral birth control pills administered for at least 2 monthly cycles prior to study drug administration, an intrauterine device (IUD), or medroxyprogesterone acetate administered intramuscularly for a minimum of one month prior to study drug administration are acceptable methods of birth control for inclusion into the study. Female subjects are considered of childbearing potential unless they are postmenopausal (absence of menstrual bleeding for 1 year - or 6 months if laboratory confirmation of hormonal status), or have had a hysterectomy, bilateral tubular ligation or bilateral ovariectomy.

9. Subjects unable to take oral medications.
10. Subject has chronic kidney or liver disease (including Hepatitis A,B or C) or known impaired hepatic and/or renal function.
11. Presence of any other pre-existing chronic infection that is undergoing or requiring medical therapy.

Summary
Brief summary
This study is a global multicenter randomized factorial double-blind, placebo-controlled trial designed to evaluate (i) efficacy and safety of nitazoxanide 600 mg administered orally twice daily for five days compared to a placebo in the treatment of acute uncomplicated influenza and (ii) efficacy and safety of combination therapy with nitazoxanide 600 mg plus Oseltamivir 75 mg co-administered orally twice daily for five days compared to nitazoxanide monotherapy (600 mg b.i.d. for 5 days) and Oseltamivir monotherapy (75 mg b.i.d. for 5 days) in the treatment of acute uncomplicated influenza.
