Study Details

Study Description

Brief Summary

This is a randomized clinical trial designed to evaluate the safety/efficacy of two dosing regimens of oral nitazoxanide compared to placebo in the treatment of acute uncomplicated influenza in adults and adolescents. The investigators hypothesize that treatment with Nitazoxanide will reduce the duration of symptoms in patients with confirmed influenza infection. Secondarily, the investigators hypothesize that treatment with nitazoxanide will reduce the complications of influenza, severity of symptoms, time lost from work, time to return to normal daily activities.

Condition or Disease Intervention/Treatment Phase
Phase 2/Phase 3

Detailed Description

A Randomized, Double-Blind, Placebo Controlled Study of Nitazoxanide in Adults and Adolescents with Acute Uncomplicated Influenza. The primary objectives of this study are to demonstrate the efficacy of nitazoxanide administered 300 mg two times per day for 5 days or 600 mg two times per day for 5 days in reducing the time to resolution of all clinical symptoms of influenza.

The study will also evaluate pharmacokinetics of nitazoxanide in a subset of 24 patients and the safety of the nitazoxanide regimen compared to a placebo via analysis of adverse events and laboratory safety tests.

Blood samples will be collected for all patients at baseline, day 7 and day 28, and for a subset of 24 patients aged 18-65 years (pharmacokinetics subset) on day 2. Urine samples will be collected at baseline and day 7. Nasal swabs will be collected at baseline and day 7 for all patients and on days 2, 3, 4 and 5 for a subset of patients (approximately 20% of patients).

    Primary Outcome Measures

    1. Time to Resolution of All Clinical Symptoms of Influenza as Reported by the Subjects [Up to 28 days]

      The primary efficacy analysis for this study was to demonstrate the efficacy of Nitazoxanide (NTZ) administered as 300 mg b.i.d. for 5 days or 600 mg b.i.d. for 5 days in reducing the time to resolution of all clinical symptoms of influenza in patients with laboratory confirmed influenza infection

    Secondary Outcome Measures

    1. Time to Resolution of Each Individual Symptom of Influenza as Reported by the Subjects [at least 28 days]

      Time in hours (Median and Interquartile range)

    2. Mean Change (Standard Deviation)in 50% Tissue Culture Infective Dose (TCID50) Viral Titer From Baseline [7 days]

      Change in viral titer presented as logarithm with base 10 (log10) 50% Tissue Culture Infective Dose (TCID50)

    3. Mean Change in RT-PCR (Reverse Transcription Polymerase Chain Reaction) Viral Titer From Baseline [7 days]

      Change in viral titer logarithm with base 10 (log10) Ribonucleic Acid (RNA)copies

      Time in hours as reported by patient

    6. Symptom Severity Score Hours [28 days]
