Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

patients infected with the SARS-CoV-2 coronavirus.

Health condition(s) code:

Coronavirus Infections

SARS Virus

Coronaviridae Infections

Betacoronavirus

Health condition keyword:

covid-19

Intervention(s):

Group A: HeberFERON (Recombinant Interferon Alpha Gamma, 3.5 MUI), subcutaneously, twice a week for three consecutive weeks. Group B (Control): Heberon Alfa R (Recombinant Interferon alfa 2b, 3.0 MUI), subcutaneously, three times per week for three consecutive weeks. All the patients included in the study (as part of the protocol of action foreseen in the country for cases of SARS-CoV-2 in nasopharyngeal exudates) receive basic treatment (in addition to interferon according to study group) with caletra, chloroquine, azithromycin or rocefin, depending on the magnitude of respiratory symptoms.

Intervention code:

Intervention keyword:

HeberFERON Kaletra Rocephin

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) Virological evaluation: Time until the negativity of the SARS-Cov-2 RNA (absence of the virus according to the qPCR technique in real time) in positive patients after starting antiviral therapy (the percentage of patients negative for SARS will be calculated). VOC-2 by qPCR in tissue of nasopharyngeal exudate Measurement time: 48, 72 and 96 hours after starting treatment. 2) Clinical evaluation: Time to progression to severe COVID-19 (the percentage of patients who become severe will be calculated). Measurement time: 3rd week, after completion of the antiviral treatment under investigation.

Key secondary outcomes:

1) Patients with unfavorable evolution (percentage of severe through clinical evaluations [fever, cough, dyspnea, etc.] and imaging (interstitial pneumonia by X-rays]). Measurement time: During the entire period of the study (three weeks). 2) Increase in the levels of markers (at the RNA and serum levels) of response to IFNs (2-5OAS, Neopterin, β-2 microglobulin, Mx protein). The average value of the serum concentration measured by quantitative ELISA of 2´-5´OAS and Neopterin will be calculated. Measurement time: before starting treatment, and 7 and 14 days after starting treatment. 3) Increased activation of the immune system (MHC-I / II expression, NK cells, cytotoxic T cells, macrophage activation). The percentage of activated cells will be calculated from the total number of patients who will receive treatment. Measurement time: before starting treatment, and 14 days after treatment. 4) Clinical Adverse Events (AE). They will be measured as: -AE occurrence (Yes, No), -AE description (name of the event), -AE intensity (mild, moderate, severe), -Causal relationship (unrelated, doubtful, possible, probable, definitive), -Measures taken (None, Administration of some pharmacological therapy, Addition of a non-pharmacological therapy, Exit of the study, Hospitalization / prolongation of hospitalization), -Result (Fully resolved, Resolved with sequelae, Conditions in improvement, Present condition and unchanged, worsening, death caused by this event). Measurement time: daily throughout the study period (three weeks).
