Overview
A subset of participants have MDS characterized by an overexpression of the RARA gene. A blood test will be used to identify participants with RARA-positive MDS. Assessment of the RARA biomarker for study eligibility will be done by collection of blood samples from potential study participants at the pre-screening visit and testing at a central laboratory. Participants who meet eligibility requirements will be randomized 2:1 to receive either Tamibarotene plus azacitidine or placebo plus azacitidine.
