Trial Outcomes & Findings for Evaluating the Efficacy of Hydroxychloroquine and Azithromycin to Prevent Hospitalization or Death in Persons With COVID-19 (NCT NCT04358068)

NCT ID: NCT04358068

Last Updated: 2021-11-16

Results Overview

Hospitalization was defined as requiring at least 24 hours of acute care in a hospital or similar acute care facility, including Emergency Rooms or temporary facilities instituted to address needs during the COVID-19 pandemic. Evaluation at a hospital or similar facility with less than 24 hours of acute care was not considered a hospitalization. Formal statistical testing was not conducted due to the small number of participants and events.

Timeframe: Day 0 to Day 20, 21 days total

Population: Participants who initiated study treatment

Defined as the time from start of study treatment to the last day in the participant's daily diary card on which a moderate or worse targeted symptom was recorded. The set of target symptoms were cough, shortness of breath, feeling feverish, fatigue, muscle aches, diarrhea, vomiting, nausea, headache, sore throat, nasal obstruction (stuffy nose), nasal discharge (runny nose), loss of smell, and loss of taste. Participants who had missing diary records due to hospitalization were assumed to have moderate symptoms during the period of hospitalization in the analysis. Missing diary card records not due to hospitalization were assumed to have absent symptoms.

SECONDARY outcome

Timeframe: Day 0 to Day 20, 21 days total

Population: Participants who initiated study treatment

Defined as the sum of scores for the targeted symptoms (defined in the protocol) in the participant's daily diary record (each symptom was scored from 0-best to 3-worst). Participant-specific areas under the curve (AUC) over time were calculated using the trapezoidal rule and defined as the area below the line formed by joining total symptom scores on each daily diary card from the pre-treatment score on Day 0 through to Day 20. AUCs were rescaled by time by dividing by 21 (corresponding to the number of daily diary cards during follow-up between pre-treatment Day 0 and Day 20), in order to provide results on a symptom scale from 0-best to 42-worst (for non-hospitalized participants). Participants who were hospitalized were assigned a value equal to the sum of the maximum possible scaled AUC (42) and the duration of hospitalization, and thus values \>42 were possible. Missing scores between pre-treatment and Day 20 were linearly interpolated. Higher AUCs indicate worse outcomes.

Timeframe: Day 0 to Day 20, 21 days total

Population: Participants who initiated study treatment

Time to self-reported return to (pre-COVID) usual health was defined as the time from the start of study treatment to the first day in the participant's daily diary card on which they responded 'Yes' with no subsequent reports of 'No' to the question "Have you returned to your usual (pre-COVID) health today?" Participants who never reported a 'Yes' response were assigned a duration of 22 days.
