Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Persons With Lower Respiratory Tract Infection (LRTI), Defined as Resting Blood Oxygen Saturation (SpO2<93%) Level Sustained for 2 Readings 2 Hours Apart and Presence of Subjective Dyspnea or Cough | 28 days from enrolment | Resting blood oxygen saturation (SpO2\<93%) level sustained for 2 readings 2 hours apart and presence of subjective dyspnea or cough |
| Primary | Number of Participants With Hospitalization or Mortality | Day 28 after enrolment | Number of participants with hospitalization or mortality |
| Primary | Time to Clearance of Nasal SARS-CoV-2 | Day 1 through Day 14 after enrolment | Time to clearance of nasal SARS-CoV-2, defined as 2 consecutive negative swabs |
| Primary | Time to Resolution of COVID-19 Symptom Resolution in Days | Day 1 through Day 14 after enrolment | COVID-19 symptoms are based on the following criteria: * At least TWO of the following symptoms: Fever (≥ 38ºC), chills, rigors, myalgia, headache, sore throat, new olfactory and taste disorder(s), OR * At least ONE of the following symptoms: cough, shortness of breath or difficulty breathing, OR * Severe respiratory illness with at least 1 of the following: * Clinical or radiological evidence of pneumonia, OR * Acute respiratory distress syndrome (ARDS), OR * LRTI, defined by resting SpO2\<93% sustained for 2 readings 2 hours apart AND presence of subjective dyspnea or cough Death or COVID-19-related hospitalizations will count as a failure to resolve symptoms. |
| Secondary | Number of Participants With Serious Adverse Events and Adverse Events Resulting in Treatment Discontinuation | 28 days from enrolment | Serious adverse events (including death and hospitalization) and adverse events resulting in treatment discontinuation |
| Secondary | COVID-19-related Hospitalization Days | 28 days from enrolment | Duration of hospitalization among persons who become hospitalized with COVID-19 disease |

| PRIMARY | Number of Persons With Lower Respiratory Tract Infection (LRTI), Defined as Resting Blood Oxygen Saturation (SpO2<93%) Level Sustained for 2 Readings 2 Hours Apart and Presence of Subjective Dyspnea or Cough | 28 days from enrolment | This outcome was analyzed in the first arm of the platform trial (Ascorbic Acid/Folic Acid HCQ, HCQ/AZ) among the high risk cohort only. The mITT cohort included only those without LRTI at baseline. | Participants | COUNT_OF_PARTICIPANTS |
| PRIMARY | Number of Participants With Hospitalization or Mortality | Day 28 after enrolment | Participants | COUNT_OF_PARTICIPANTS | |
| PRIMARY | Time to Clearance of Nasal SARS-CoV-2 | Day 1 through Day 14 after enrolment | Included the mITT viral shedding cohort, which includes the mITT cohort participants who do not meet the definition for clearance of viral shedding at baseline (day 1 and 2 swabs negative). | Days | MEDIAN |
| PRIMARY | Time to Resolution of COVID-19 Symptom Resolution in Days | Day 1 through Day 14 after enrolment | mITT Disease Resolution cohort includes participants who meet the COVID-19 disease criteria on day 1. The symptom resolution rate was the primary outcome of the lopinavir-ritonavir adaptive platform arms (lopinavir-ritonavir and ascorbic acid). | Days | MEDIAN |
| SECONDARY | Number of Participants With Serious Adverse Events and Adverse Events Resulting in Treatment Discontinuation | 28 days from enrolment | All enrolled participants | Participants | COUNT_OF_PARTICIPANTS |
