| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Proportion of Patients With Clinical Symptom Requiring Hospitalization, Oxygen Therapy, or Experiencing Mortality Due to SARS-CoV-2 Infection (Part 1) | Up to Day 28 | To assess the clinically meaningful therapeutic efficacy of CT-P59 as determined by proportion of patients with clinical symptom requiring hospitalization, oxygen therapy, or experiencing mortality due to SARS-CoV-2 infection up to Day 28 |
| Primary | Proportion of Patients With Negative Conversion in Nasopharyngeal Swab Specimen Based on RT-qPCR at Each Visit (Part 1) | Up to Day 14 | To assess the potential therapeutic efficacy of CT-P59 as determined by proportion of negative conversion in nasopharyngeal swab specimen based on RT-qPCR up to Day 14 |
| Primary | Time to Negative Conversion in Nasopharyngeal Swab Specimen (Part 1) | Up to Day 14 | To evaluate the therapeutic efficacy of CT-P59 as determined by time to negative conversion by RT-qPCR up to Day 14 |
| Primary | Time to Clinical Recovery (Part 1) | Up to Day 14 | To assess the potential therapeutic efficacy of CT-P59 as determined by time to clinical recovery up to Day 14. Clinical recovery was defined as all symptoms on the SARS-CoV-2 Infection Symptom Checklist 1 being recorded as 'absent' or 'mild' in intensity for at least 48 hours. SARS-CoV-2 Infection Symptom Checklist 1 consisted of 7 symptoms (feeling feverish, cough, shortness of breath or difficulty breathing, sore throat, body pain or muscle pain, fatigue, and headache) and the intensity of patient's self-aware for each SARS-CoV-2 infection symptom (absent \[0\], mild \[1\]. moderate \[2\], and severe \[3\]). To meet the clinical recovery, symptoms 'severe' or 'moderate' in intensity at baseline should be changed to 'mild' or 'absent', or symptoms 'mild' in intensity at baseline should be changed to 'absent', after the study drug administration. Symptoms "absent" in intensity at baseline should maintain as "absent" for at least 48 hours. |
| Primary | Proportion of Patients With Clinical Symptom Requiring Hospitalization, Oxygen Therapy, or Experiencing Mortality Due to SARS-CoV-2 Infection up to Day 28 in High-risk Patients (Part 2) | Up to Day 28 | To demonstrate the clinically meaningful therapeutic efficacy of CT-P59 as determined by proportion of patients with clinical symptom requiring hospitalization, oxygen therapy, or experiencing mortality due to SARS-CoV-2 infection up to Day 28 in high-risk patients |
| Secondary | Proportion of Patients With Clinical Symptom Requiring Hospitalization, Oxygen Therapy, or Experiencing Mortality Due to SARS-CoV-2 Infection up to Day 28 in All Randomized Patients (Part 2) | Up to Day 28 | To demonstrate the clinically meaningful therapeutic efficacy of CT-P59 as determined by proportion of patients with clinical symptom requiring hospitalization, oxygen therapy, or experiencing mortality due to SARS-CoV-2 infection up to Day 28 in all randomized patients |
| Secondary | Time to Clinical Recovery up to Day 14 in High-risk Patients (Part 2) | Up to Day 14 | To assess the potential therapeutic efficacy of CT-P59 as determined by time to clinical recovery up to Day 14 in high-risk patients. Clinical recovery was defined as all symptoms on the SARS-CoV-2 Infection Symptom Checklist 1 being recorded as 'absent' or 'mild' in intensity for at least 48 hours. SARS-CoV-2 Infection Symptom Checklist 1 consisted of 7 symptoms (feeling feverish, cough, shortness of breath or difficulty breathing, sore throat, body pain or muscle pain, fatigue, and headache) and the intensity of patient's self-aware for each SARS-CoV-2 infection symptom (absent \[0\], mild \[1\]. moderate \[2\], and severe \[3\]). To meet the clinical recovery, symptoms 'severe' or 'moderate' in intensity at baseline should be changed to 'mild' or 'absent', or symptoms 'mild' in intensity at baseline should be changed to 'absent', after the study drug administration. Symptoms "absent" in intensity at baseline should maintain as "absent" for at least 48 hours. |
| Secondary | Time to Clinical Recovery up to Day 14 in All Randomized Patients (Part 2) | Up to Day 14 | To assess the potential therapeutic efficacy of CT-P59 as determined by time to clinical recovery up to Day 14 in all randomized patients. Clinical recovery was defined as all symptoms on the SARS-CoV-2 Infection Symptom Checklist 1 being recorded as 'absent' or 'mild' in intensity for at least 48 hours. SARS-CoV-2 Infection Symptom Checklist 1 consisted of 7 symptoms (feeling feverish, cough, shortness of breath or difficulty breathing, sore throat, body pain or muscle pain, fatigue, and headache) and the intensity of patient's self-aware for each SARS-CoV-2 infection symptom (absent \[0\], mild \[1\]. moderate \[2\], and severe \[3\]).

| Secondary | Proportion of Patients With Hospital Admission Due to SARS-CoV-2 Infection (Part 1 and Part 2) | Up to Day 28 | To evaluate the additional efficacy of CT-P59 |
| Secondary | Proportion of Patients Requiring Supplemental Oxygen Due to SARS-CoV-2 Infection (Part 1 and Part 2) | Up to Day 28 | To evaluate the additional efficacy of CT-P59 |
