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):

Levels of local and systemic expression of markers of activity of the cellular signaling system stimulated by IFN alpha (2-5 oligo adenylate synthetase for antiviral activity and β2-microglobulin for activity of the immune system), evaluated by PCR on tissue obtained from nasal scraping and sublingual (for evaluations at the local level) and in peripheral blood (for evaluations at the systemic level). Measurement time: At baseline, 72 hours after the first administration of IFN alfa and, 24 hours after the last administration.

Key secondary outcomes:

1) Levels of local and systematic expression of other pharmacodynamic markers (STAT-1 and STAT-3 as markers of stimulation of IFNs signaling and expression of Toll-like receptors 3 and 7 as markers of activation of the immune system) nasal scraping and sublingual. Measurement time: At baseline, 72 hours after the first administration of IFN alfa and, 24 hours after the last administration. 2) Levels of blood expression of NK cells, lymphocytes, activation of macrophages and HLD-DR (by flow cytometry). Measurement time: At baseline and, 24 hours after the last administration. 3) Clinical Adverse Events-A (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 any 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 five days.
