Conditions

Chronic fatigue syndrome associated with post-COVID syndrome

Brief summary

Change in fatigue intensity expressed as a difference in Multidimensional Fatigue Inventory-20 (MFI-20) score at 3 and 6 months of the study relative to the baseline score., Walking distance as a difference in score from the 6 Minute Walking Test at 3 and 6 months compared to baseline.

Detailed description

We allow for the possibility of additional exploratory endpoints during the study, before unblinding., Security related endpoints: • Number of adverse events and the number and percentage of patients who experienced adverse events. • Number of adverse events and the number and proportion of patients who experienced treatment-related adverse events. • Number of serious adverse events and number and proportion of patients with serious adverse events. • Number of serious adverse events and the number and proportion of patients who experienced treatment-related serious adverse events., Number and percentage of patients who discontinued participation in the study due to an adverse event - changes in laboratory parameters and basic vital signs.
