About this study

This is a multicentre, randomized, parallel-group, placebo-controlled, double-blind phase 2 study of the efficacy and safety of oral vitamin C supplement in combination with azacitidine in patients with higher-risk MDS, CMML-2 or low-blast count AML. The primary purpose is to investigate if oral vitamin C supplementation to azacitidine, compared with azacitidine + placebo, can increase the effectiveness of epigenetic therapy in patients with higher-risk myeloid malignancies, who are not candidates for allogeneic hematopoietic stem cell transplantation.
