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):

Activation of markers of the innate immune system (levels of TLR3, TLR7, or TLR8): Measurement time: at baseline and, on day 15 (end of treatment).

Key secondary outcomes:

1. Percentage of patients with increased expression of TLR3; TLR7; TLR8. Measurement time: at baseline and on days 8 and 15 post-treatment. 2. Clinical Adverse Events-AE (They will be measured as: -AE occurrence (Yes, No), -AE description (name of 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 follow-up of the subjects.
