简要总结
EVIDENCE is a non interventional, French, multicenter study. Patients will be screened by local severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoassay in their oncology department (rapid diagnostic test (RDT) or enzyme-linked immunosorbent assay (ELISA)). In patients with positive local SARS-CoV-2 immunoassay, a centralized SARS-CoV-2 ELISA will be performed in order to double check the immune response of all patients considered immune by local immunoassay.
详细描述
Patients with cancer are a high-risk group in the COVID-19 pandemic. They are already vulnerable to infection because of their underlying illness and often immunosuppressed status, and are at increased risk of developing severe complications from the virus, including intensive care unit admission or even death. In light of this increased risk, many guidelines have been issued, aiming at minimizing the risk of SARS-CoV-2 infection occurrence and/or gravity. These changes in cancer care could however translate in less efficient or delayed treatments. In this study, we want to detect cancer patients that were exposed to the SARS-CoV-2 virus and acquired an immunity. These patients immune to the SARS-CoV-2 virus are susceptible to receive the standard of care, meaning the most appropriate treatment to manage their cancer. Large-scale serodiagnosis are considered as the solution to progressively relax the current lockdown in France. RDT and ELISA, which were not available until mid-April 2020, will be largely used in the general French population over the coming months, millions of tests have already been ordered by French authorities and companies.
The aim of this study is to control that oncology patients qualified immune by local immunoassay are indeed safe (i.e. have extremely low risk of SARS-CoV-2 infection following a positive local immunoassay test). Of note, several immunoassays (RDT or ELISA) will be used in the participating centers throughout the study. A confirmation of positive cases yielded by these different immunoassays will be performed by a centralized ELISA, in order to minimize the risk of false positive results.

结局指标
主要结局
To evaluate the ability of SARS-CoV-2 immunoassays, following a positive result, to identify patients with very low risk of recurrence of COVID-19 within 3 months.
时间窗: 3 months
The primary endpoint of this study is the recurrence of COVID-19 within 3 months following the immunoassay-positive result obtained before the inclusion in the study. The recurrence is defined by the presence of symptoms confirmed either by a positive reverse transcription-polymerase chain reaction (RT-PCR) result for SARS-CoV-2 or by the adjudication committee. Immunoassay will be said positive as per the predefined reference corresponding to the immunoassay.
次要结局
- To identify patients with very low risk of recurrence of COVID-19 within 6 months following a positive immunoassay result.(6 months)
- To estimate the discordance rate between local immunoassay and a centralized ELISA in patients with a positive immunoassay, whatever the immunoassay.(6 months)
- To characterize the evolution over time of the serologic response against SARS-CoV-2 (in a subgroup of patients).(6 months)
