Detailed Description

This is a multicenter, parallel, double-blind, randomized, placebo-controlled study. A total of 258 male or unpregnant female outpatient subjects ≥ 18 years to ≤ 79 years of age will be enrolled into this study (dropout rate 10%). There will be 2 visits in this study. In Visit 1 (Day 1), subjects who have the symptoms of fever, sore throat, and cough (match the definition in table 1 to 3 in protocol), by investigator's judgement will be recruited into the study. Subjects will be randomized into the RespireAidTM group or placebo group with allocation rate 2:1. Following to the clinical guideline of NRICM101, subjects in RespireAidTM group will take drug four times daily with 20g oral granule, administered for 5 days. The subjects in placebo group received study drug with the same dose frequency. Other than study drugs, the rescue drug, acetaminophen, will be administered. If subjects have moderate or severe fever, sore throat, he/she could receive one rescue medication (500mg) per 4 hours, up to 6 tablets in total in one day. Subjects will be educated how to use e-dairy. The dairy will be recorded the severity of fever, sore throat, and cough from baseline (Day 1, before use of study drug) to Day 5. The efficacy endpoint will be the improvement of fever, sore throat, and cough, and the safety endpoint will be adverse events after treatment. The study and rescue drugs will be dispensed to subjects and the study staff will teach them how to receive medications. If subjects have persistent fever, unscheduled visits will be arranged to check whether or not they would be suitable to participate into this study.

Adverse events will be recorded at Visit 2(Day 8), and the dairy with drug record will be checked.
