Clinical Trial Summary

DisCoVeRy is a randomized controlled trial among adults (≥18-year-old) hospitalized for COVID-19. This study is an adaptive, randomized, open or blinded, depending on the drug to be evaluated, clinical trial to evaluate the safety and efficacy of possible therapeutic agents in hospitalized adult patients diagnosed with COVID-19. The study is a multi-centre/country trial that will be conducted in various sites in Europe with Inserm as sponsor. The study will compare different investigational therapeutic agents to a control group managed with the SoC including corticosteroids and anticoagulants. There will be interim monitoring to allow early stopping for safety and to introduce new therapies as they become available. If one therapy proves to be superior to others in the trial, this treatment may become part of the SoC for comparison(s) with new experimental treatment(s). In previous versions of the DisCoVeRy protocol, remdesivir, lopinavir/ritonavir with or without interferon ß-1a and hydroxychloroquine were evaluated as potential treatments for COVID-19. These treatments have been discontinued based on analyses review by both DSMC/DSMB, the Solidarity Executive Group and the DisCoVeRy steering committee. This version of the protocol, therefore, describes a randomized blinded placebo-controlled trial among adults (≥18-year-old) hospitalized for COVID-19 that randomly allocates them (1:1 ratio) between 2 arms: SoC + placebo versus SoC + AZD7442. Randomization will be stratified by region (according to the administrative definition in each country), antigenic status (positive or negative) obtained from the result of a rapid antigen test on nasopharyngeal swab performed at enrolment and vaccination initiation (yes or no). The primary analyses will be conducted on patients with antigen-positive results. A positive antigenic test is evidence of high viral shedding consistent with a recently started or uncontrolled infection. Overall, the number of antigen-negative patients will be at most 30% of all included subjects. The number of patients with vaccination (partly or fully) will be limited to 20% of all participants, split evenly between antigen positive and antigen negative patients (i.e. vaccinated patients can make up at most 20% of antigene positive patients and 20% of antigene negative patients). Sensitivity analyses will be performed in all patients, stratified by antigenic status and vaccination initiation. A global independent data and safety monitoring board (DSMB) monitors interim data to make recommendations about early study closure or changes to conduct, including adding or removing treatment arms. However, the current version of the protocol does not allow for efficacy or futility analysis, and the ability to add trial arms will be limited by the study being blinded and placebo-controlled during the investigation of AZD7442.

This version of the protocol, therefore, describes a randomized blinded placebo-controlled trial among adults (≥18-year-old) hospitalized for COVID-19 that randomly allocates them (1:1 ratio) between 2 arms: SoC + placebo versus SoC + AZD7442. Randomization will be stratified by region (according to the administrative definition in each country), antigenic status (positive or negative) obtained from the result of a rapid antigen test on nasopharyngeal swab performed at enrolment and vaccination initiation (yes if at least one injection of any vaccine against SARS-CoV-2 was reveived prior to enrolment whatever the delay or no). The primary analyses will be conducted on patients with antigen-positive results. A positive antigenic test is evidence of high viral shedding consistent with a recently started or uncontrolled infection. Overall, the number of antigen-negative patients will be at most 30% of all included subjects. The number of patients with vaccination (partly or fully) will be limited to 20% of all participants, split evenly between antigen positive and antigen negative patients (i.e. vaccinated patients can make up at most 20% of antigene positive patients and 20% of antigene negative patients). Sensitivity analyses will be performed in all patients, stratified by antigenic status and vaccination initiation. A global independent data and safety monitoring board (DSMB) monitors interim data to make recommendations about early study closure or changes to conduct, including adding or removing treatment arms. However, the current version of the protocol does not allow for efficacy or futility analysis, and the ability to add trial arms will be limited by the study being blinded and placebo-controlled during the investigation of AZD7442. All subjects will undergo a series of efficacy and safety assessments, including laboratory assays. Subjects will be assessed at baseline, and at Days 3, 8 and 15 while hospitalized. Patients will be contacted by phone at Day 15 for evaluation of the Primary Endpoint if they have been discharged prior to Day 15-, and 14-days following hospital discharge for efficacy assessment. Further follow-up assessments will be organized at Days 29, 90, 180, 365 and 456. If discharged from the hospital, days 29 and 90 assessments will be organized as outpatients' consultations for all. For Days 180 and 365 assessments, a subset of 25% of patients enrolled in centers with available resources and selected at Day 90 will be evaluated during a medical consultation, while the other will be contacted by phone. For Day 456, all patients will be contacted by phone. Nasopharyngeal swabs (NP) or lower respiratory tract samples will be obtained at baseline (Day 1 pre-treatment) and at Days 3, 8, 15 (while hospitalized) and 29 (while hospitalized or, if discharged from the hospital, in the outpatient setting). Blood samples will be obtained at baseline (Day 1 pre-treatment) and at Days 3, 8, 15 (while hospitalized), at Days 29 and 90, and at Days 180 and 365 (for the subset of patients evaluated during a medical consultation at these times). Thoracic computed tomography (CT)-scan will be obtained at baseline, depending on the centre's imagery capacities.
