Clinical Trial Summary

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected the global population with significant morbidity and mortality. One of the main concerns is the management of the patients since there is no specific treatment for this condition. Therefore, in SARS-CoV-2 patients the compassionate use of off-label therapies has been initiated; such as the use of plasma from convalescent patients. This treatment has been used in other pandemics like SARS-CoV-1, H5N1, H1N1, Ebola, among others. This study is a phase II/III randomized clinical trial to assess the effectiveness and safety of convalescent plasma administration in patients with high-risk SARS-CoV-2.

Description:

This is a Phase II/III randomized clinical trial to assess the effectiveness and safety of anti-SARS-CoV-2 convalescent plasma in i) hospitalized adult patients with high-risk of progression SARS-CoV-2 infection and ii) patients in Intensive Care Unit (ICU).

Compatible ABO plasma from convalescent patients will be administered at a dose of 400 ml divided into two doses intravenously. Outcomes will be measured as follows:

• Group of patients with critical illness:

Primary outcomes (Effectiveness and safety):

• Mortality

• Safety: Presence of adverse events

Secondary outcomes:

• Intensive care unit length of stay

• Evolution of clinical and paraclinical aspects.

• Group of patients at high risk of progression:

Primary outcomes (Effectiveness and safety):

• Mortality

• Safety: Presence of adverse events

• Admission to ICU in 30 days

• Mechanical ventilation requirement

Secondary outcomes:

• Hospital/Intensive care unit length of stay

• Evolution of clinical and paraclinical aspects.
