Treatment of mild COVID-19 is basically performed at an outpatient clinic, then when thesymptom and clinical findings exacerbate to a moderate level, patients are admitted.There is no standard treatment for mild cases. This study will investigate whetherivermectin administration suppresses the replication of SARS-CoV-2 in mild to moderateCOVID-19 by investigating the negative rate of SARS-CoV-2 PCR by a randomized controlledtrial. Subjects are assigned to two groups, the placebo group, and the ivermectin group.The target number of each treatment arm is 120, a total of 240 cases. A single oraladministration of 200 ㎍/kg of ivermectin or an ivermectin-free placebo will beadministered on an empty stomach. Time to negativization of SARS-CoV-2 PCR as the primaryendpoint with additional efficacy and safety of the process will be investigated.
Drug: Ivermectin 3 MG
Ivermectin approximately 200 μg/kg administered as a single oral dose on Day 1 (fasting
state)
Drug: Placebo
Placebo group: Placebo without ivermectin as an ingredient, single oral administration on
Day 1 (fasting state)

3. A person with hypersensitivity to ivermectin.
  4. A person with a history of severe drug allergies such as Stevens-Johnson syndrome,
     toxic epidermal necrolysis.
  5. A person who has received the prohibited medication within the past month (within
     the past 6 months for biologics), or those who need to use the prohibited medication
     during the clinical trial period.
  6. Those who are scheduled to receive SARS-CoV-2 vaccination from the date of consent
     to the end of the follow-up period.
  7. A person who are currently participating in other clinical trials or who have
     participated in other clinical trials within 30 days before obtaining consent.
  8. In addition, a person who is determined to be unsuitable as a subject of this
