Brief Summary:

The health contingency established against the Severe Acute Respiratory Syndrome associated type 2 Coronavirus (SARS-CoV-2) has promoted a race against the clock for the search on treatment against the disease related with coronavirus (COVID-19). There are no current approved therapeutic options against the virus, although there is a rush for the development of drugs, vaccines and even the passive immunization through plasma from convalescent patients. This passive immunization is made with the administration of antibodies from patients that went through the infectious state of the disease and progress to clinical remission.

SARS-CoV-2, and its predecessor SARS-CoV-1, have great similarities between their genes and proteins; tis allow to hypothesize that the antibodies developed against SARS-CoV1 can recognize the antigens of SARS-CoV-2. In this manner, the transfusion of convalescent plasma to patients with the infection brings the probability on eliminating the infection, in this case SARS-CoV-2. There are evidence of this phenomenon observed in previous pandemics caused by SARS-CoV-1, Influenza AH1N1 and Ebola virus.

The objective of the study is to develop a therapeutic strategy based on the administration of plasma from patients with COVID-19 with clinical remission to patients that are coursing with the infection. The expected results hopes to establish an effective treatment and satisfactory recovery of patients with COVID-19. Also, we expect to describe the respective antibodies related against the SARS-CoV-2 infection.

Arm Intervention/treatment
Experimental: Convalescent plasma

Best available treatment + convalescent plasma

Best available treatment: hemodynamic support, oxygen supplementation, antibiotic therapy (if required), and individualized treatment judged by the attending physician.

Plasma will be split by aliquots of 200 ml for its storage on -60 celsius degrees until it's used. After defrosting, it will be administered on 2 200 ml separated doses on a 12 hours interval.

 Biological: Convalescent plasma

Best available treatment + convalescent plasma

Best available treatment: hemodynamic support, oxygen supplementation, antibiotic therapy (if required), and individualized treatment judged by the attending physician.

Plasma will be split by aliquots of 200 ml for its storage on -60 celsius degrees until it's used. After defrosting, it will be administered on 2 200 ml separated doses on a 12 hours interval.
Placebo Comparator: Best available treatment

Best available treatment + Placebo (0.9% saline solution)

Best available treatment: hemodynamic support, oxygen supplementation, antibiotic therapy (if required), and individualized treatment judged by the attending physician.

Placebo will consist on 2 doses of 200 ml of 0.9% saline solution separated on a 12 hour interval.

 Biological: Convalescent plasma

Best available treatment + convalescent plasma

Best available treatment: hemodynamic support, oxygen supplementation, antibiotic therapy (if required), and individualized treatment judged by the attending physician.

Plasma will be split by aliquots of 200 ml for its storage on -60 celsius degrees until it's used. After defrosting, it will be administered on 2 200 ml separated doses on a 12 hours interval.
