COVID-19 respiratory distress

Health condition(s) code:

Coronavirus Infections

SARS Virus

Coronaviridae Infections

Betacoronavirus

Severe Acute Respiratory Syndrome

Respiratory Tract Diseases

Health condition keyword:

COVID-19

Intervention(s):

- Group I: CIGB-258 peptide (Jusvinza, CIGB, Havana, Cuba) + standard therapy according to the interim algorithms for the care of COVID-19 established by the IMSS. Patients WITH mechanical ventilation: 1 mg intravenously every 12 hours until extubation of the patient. After weaning, administer 1 mg intravenously every 24 hours for three days. If there is no clinical, gasometric and radiological improvement after 24-48 hours, the dose can be increased to 2 mg, with a frequency of 12 hours (at the discretion of the practitioner). Total dose / day: 4 mg. Patients WITHOUT mechanical ventilation: 1 mg intravenously every 12 hours until the patient reverses his condition (no need for oxygen therapy, or signs and / or symptoms of acute respiratory failure). If at 72 hours there is no clinical, gasometric and radiological improvement (or earlier, if the patient requires mechanical ventilation), the dose can be increased to 2 mg, with a frequency of 12 hours (at the discretion of the practitioner). Total dose / day: 4 mg. If after the 7th day of a patient receiving the maximum dose of CIGB-258 peptide (2 mg every 12 hours) no clinical, gasometric and radiological improvement is observed, the doctor may consider suspending this therapy or not (and start another treatment out of protocol). - Group II (Control): Standard therapy according to the interim algorithms for COVID-19 care established by the IMSS.

Intervention code:

Peptides

Respiration, Artificial

Administration, Intravenous

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

1) Mortality on discharge from the Hospital (Proportion of patients who die (global and by strata: serious and critical) according to their causes and treatment groups, during their stay at the CMN Siglo XXI Specialty Hospital). Measurement time: during hospital stay. 2) Need for invasive mechanical ventilation (orotracheal intubation) in critically ill patients and, time (in days) from intubation to weaning in critically ill (if applicable) and critical patients. Measurement time: During the stay in the COVID-19 internment area, until ventilatory weaning.

Key secondary outcomes:

1) Reduction in the deterioration of lung function (Proportion of patients who did not require an increase in FiO2 to keep SO2 stable and without the need for intubation and / or Percentage of patients who decreased positive pressure values at the end of expiration [PEEP] ). Measurement time: On the 7th day after starting the treatment. 2) Need and time (in days) of non-invasive mechanical ventilation and/or oxygen therapy. Measurement time: During the stay in the COVID-19 internment area. 3) Measurement of hyperinflammation score parameters (temperature, visceromegaly, cytopenias, triglycerides, aspartate aminotransferase - TGO, fibrinogen, ferritin, D-dimer). Measurement time: at the beginning, at 72 hours and on the 7th day after starting the treatment. 4) Stay (days) in the COVID-19 internment area and global hospita (Time from the inclusion in the trial, in the COVID-19 internment area, until discharge from said area, as well as the global time of stay in the hospital (from admission to discharge)). Measurement time: during the stay in the COVID-19 internment area and hospital in general. 5) Sequential organ failure evaluation (SOFA score). Measurement time: daily, during the stay in the COVID-19 internment area. 6) Immunological evaluation through the determination of pro and anti-inflammatory cytokines and chemokines (IL-2, IL-4, IL-6, IL-10, IL-17, TNF, IFN alpha, IFN gamma, CXCL8, CCL5, CXCL9 , CCL2, CXCL10) through multiple bead-based immunoassays, with quantification of Th1, Th2 and TH17 type cytokines, chemokines and IFN alpha in human serum. Measurement time: at the beginning, at 72 hours and on the 7th day after starting the treatment. 8) Behavior of biomarkers: absolute lymphocyte count, C-reactive protein, erythrocyte sedimentation rate, lactate dehydrogenase - LDH, etc. Measurement time: at the beginning, 72 hours and 7th day after the start of treatment. 9) Antibody titers: IgM and IgG antibody titers against the S protein of the SARS-CoV-2 virus will be measured by ELISA. Measurement time: at the beginning, at 72 hours and on the 7th day after starting the treatment. 10) Cellular immunophenotype: It will be carried out through the analysis of cell populations by flow cytometry and confocal microscopy, using the markers: CD11c, MHC-II and BDCA-3, MDC-8, CD86, CD40, PDL-1, INF- α, TNF-α PD-1 and PD-L1, CTLA- and TIM-3 and IDO, CD103, CD69, CD44, CD62L CD3, CD4, CD8, INF-γ and granzyme B. Measurement time: at baseline, at 72 hours and on the 7th day after starting the treatment. 11) Imaging response: the evolution of pulmonary lesions will be evaluated by chest radiography, CT or pulmonary ultrasound. Measurement time: at the beginning, at 72 hours and on the 7th day after starting the treatment (and when clinically indicated). 12) Clinical Adverse Events-AE (They will be measured as: -Occurrence of AE (Yes, No), -Description of AE (name of event), -Intensity of AE (mild, moderate, severe), -Causality relationship (no related, doubtful, possible, probable, definitive), -Measures adopted (None, Administration of any pharmacological therapy, Addition of a non-pharmacological therapy, Study exit, Hospitalization / prolongation of hospitalization), -Result (Completely resolved, Resolved with sequelae, Conditions improving, Condition present and unchanged, Worsening, Death caused by this event)). Measurement time: daily during the entire period of admission to the COVID-19 internment area.
