Trial outcomes
Primary outcomes
Prorated AUC for the global BFI score
The prorated AUC for the global BFI score (average scores of 9 items), usual fatigue (item2) and worst fatigue (item 3) will be compared between PG2 and the placebo arms at the end of the study.
Secondary outcomes
Fatigue improvement response rate (FIRR)
FIRR is defined as those with at least 10% reduction from baseline in the total BFI scores after 8-week treatment. 20% and 30% reduction will also be evaluated.
