Time frame
From the date of randomization of study drug up to the treatment period; up to the data cut-off date of 25 January 2019; median duration of treatment to oral azacitidine was 5.29 months and 5.36 months for placebo

What was measured

Platelet transfusion independence was defined as the absence of any platelet transfusion during any consecutive "rolling" 56 days during the treatment period, (ie, Day 1 to 56, Day 2 to 57, Days 3 to 58, etc.). Participants were considered platelet transfusion dependent at baseline if they had received ≥ 2 platelet transfusions during the 56 days immediately preceding randomization and had no consecutive 28-day period during which no platelet transfusions were administered.

Analysis population: ITT population; includes participants who were baseline platelet transfusion dependent.

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.
