Study objectives:

Primary objectives:

The primary objective of this trial is to investigate if oral vitamin C supplementation increases the efficacy of azacitidine (AZA) treatment in AZA-naïve patients with higher-risk MDS, CMML-2 or low-blast count AML (20-30% blasts). The efficacy of oral vitamin C in combination with AZA will be assessed by duration of AZA therapy in patients randomized to AZA + oral vitamin C compared to patients randomized to AZA + placebo. AZA treatment duration represents a composite measure of rate of response to AZA therapy and duration of response.

Secondary objectives:

  1. Number and rate of adverse events and serious adverse events
  2. Overall survival in months
  3. Rate of overall response and rates of individual responses (as according to international consensus criteria)
  4. Change in patient-reported outcome (PRO) measures including health-related quality of life scores (EORTC QLQ-C30 and Hematological Malignancy (HM)-PRO)
  5. Change in variant allele frequency of mutated clones in bone marrow mononuclear cells
  6. Change in global 5-hydroxymethylcytosine (hmC)/5-methylcytosine (mC) in bone marrow CD34+ cells
  7. Change in 5-hmC/5-mC at specific loci at promoters/enhancers/long terminal repeats or at other regulatory genomic regions of tumor suppressors, oncogenes, genes involved in hematopoietic development or human endogenous retrovirus (HERV) in bone marrow CD34+ cells
  8. Change in expression of genes involved in viral defense pathways, cell differentiation and tumor suppression in bone marrow CD34+ cells
  1. Change in levels of mRNA expression of HERV in bone marrow CD34+ cells and HERV specific T-cell responses
