What was measured

A clinically meaningful improvement or deterioration was defined by domain specific thresholds of change from baseline. The FACT-An questionnaire is a 47-item, cancer specific questionnaire consisting of a core 27 items measuring 4 general domains physical well being, social/family, emotional well being and Functional Well-Being and an additional 20-item anemia questionnaire that measures fatigue and 7 non-fatigue items. The scales are formatted on 4 pages for self-administration using a 5-point Likert rating scale (0 = Not at all; 1 = A little bit; 2 = Somewhat; 3 = Quite a Bit and 4 = Very much). Also, general HRQoL measures the impact of fatigue and other anemia-related symptoms on patient functioning and is used to assess the effect of treatments in various areas, including MDS. The instrument and the fatigue and non-fatigue subscales are scored by summing points from all questions, then converting this sum to a 100 point scale; 0 = the poorest QOL and 100 = the highest QOL.

Analysis population: The HRQoL evaluable population was defined as participants with a non-missing FACT-An Trial Outcome Index (TOI) score baseline visit and at least one post-baseline assessment visit.

Groups in this outcome

Oral Azacitidine and Best Supportive Care

Participants received 300 mg oral azacitidine tablets daily on days 1 to 21 of each 28-day treatment cycle and BSC included and was not limited to pRBC (packed red blood cell \[pRBC\] and whole blood), platelet transfusions (single donor or pooled donor), antibiotic, antiviral and/or antifungal therapy, nutritional support, and granulocyte colony stimulating factors (G-CSF) for participants who experienced neutropenic fever/infections.

Placebo Plus Best Supportive Care

Participants received identically matching placebo tablets QD on days 1 to 21 of each 28-day treatment cycle and BSC which included but was not limited to, pRBC and whole blood, platelet transfusions (single donor or pooled donor), antibiotic, antiviral and/or antifungal therapy, nutritional support, and G-CSF for participants who experienced neutropenic fever/infections.
