To Evaluate the Efficacy and Safety of TG-1000 Compared With Placebo in Adult Patients With Acute Uncomplicated Influenza Virus Infection
A Phase 2, Multicenter, Randomized, Double-blind, Dose-ranging Study to Evaluate the Efficacy and Safety of TG-1000 Compared With Placebo in Adult Patients With Acute Uncomplicated Influenza Virus Infection
Study Overview
Detailed Description
This study is a multicenter, randomized, double-blind, dose-ranging study to evaluate the efficacy and safety of different doses of TG-1000 compared with placebo in adult patients with acute uncomplicated influenza virus infection.
Approximately 200 patients will be randomly assigned to 1 of 4 treatments groups in a ratio of 1:1:1:1 to receive study treatment orally: "40 mg TG-1000", "80 mg TG-1000", "40mg+40mg TG-1000" or "placebo".

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The antiviral effect of TG-1000 compared with placebo in adult patients with acute uncomplicated influenza virus infection.
Time Frame: Up to Day 9
|
The time between the initiation of the study treatment and the first time when the influenza virus RNA cannot be detected.
|
Up to Day 9
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to alleviation of all influenza symptoms.
Time Frame: Up to Day 9
|
The time between the initiation of the study treatment and the alleviation of influenza symptoms.
|
Up to Day 9
|
The percentage of patients have positive for virus RNA by real time polymerase chain reaction(RT-PCR).
Time Frame: Up to Day 9
|
The percentage of patients positive for virus RNA by RT-PCR.
|
Up to Day 9
|
The change from baseline in virus RNA by RT-PCR (unit: log₁₀ virus particles/mL).
Time Frame: Up to Day 9
|
The change from baseline in the amount of virus RNA.
|
Up to Day 9
|
Area Under the Concentration (AUC) of virus RNA by RT-PCR and AUC of virus titer.
Time Frame: Up to Day 9
|
AUC of the viral load by RT-PCR and AUC of viral titer measured from baseline to Day 9±2 or early termination (Visit 5).
|
Up to Day 9
|
The percentage of patients whose symptoms have been alleviated at each time point.
Time Frame: Up to Day 9
|
The percentage of patients whose symptoms are alleviated at each time point.
|
Up to Day 9
|
The percentage of patients reporting normal temperature at each time point.
Time Frame: Up to Day 9
|
The percentage of patients whose axillary temperature drops to less than 37ºC after the initiation of the study treatment in the analysis population.
|
Up to Day 9
|
Time to resolution of fever.
Time Frame: Up to Day 9
|
The time between the initiation of the study treatment and the resolution of fever.
|
Up to Day 9
|
Body temperature at each time point.
Time Frame: Up to Day 9
|
Measured axillary temperature.
|
Up to Day 9
|
Time to return to preinfluenza health status.
Time Frame: Up to Day 9
|
Patients will be asked to record their pre-influenza health status between 0 (worst possible health) and 10 (normal health).
|
Up to Day 9
|
The visual analog scale (VAS) score change from baseline of quality of life (QOL) questionnaire.
Time Frame: Up to Day 9
|
The VAS score change from baseline of QOL questionnaire.The QOL questionnaire consists 2 sections: the descriptive system and the VAS.
The descriptive system comprises 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each of which is divided into 5 levels.
The VAS records the patient's self-rated health on a 20-cm vertical visual analogue with "the best health the patient can imagine" as 100 and "the worst health the patient can imagine" as 0.
