Could a gentler dose of an oral chemo drug help MDS patients avoid transfusions?
NCT ID NCT03502668
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an oral drug called ASTX727 in people with lower-risk myelodysplastic syndromes (MDS), a bone marrow disorder. The goal was to see if a lower dose given over a longer schedule could improve blood cell counts and reduce the need for transfusions. The trial enrolled 160 adults and looked at safety and effectiveness in two phases.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ASTX727 (oral decitabine and cedazuridine)
- What this could lead to
- If successful, this could offer a more convenient oral treatment option for people with lower-risk MDS, potentially improving blood cell counts and reducing transfusion needs.
- What could go wrong
- This is an early-phase trial with small groups, so results may not confirm benefit. The drug can cause side effects like low blood counts or infections.

Inclusion Criteria: 1. Able to understand and comply with the study procedures, understand the risks involved in the study, and provide written informed consent before the first study-specific procedure. 2. Men or women ≥18 years with IPSS low risk or Int-1 MDS (all subjects). Subjects must have had at least 1 of the following disease-related criteria during the 8 weeks before randomization: 1. Red blood cell (RBC) transfusion dependence of 2 or more units of RBC transfusions (RBC transfusion administered for hemoglobin (Hb) levels ≤9.0 g/dL are counted). 2. Hb of \<9.0 g/dL in at least 2 blood counts prior to randomization or in 1 blood count if RBC transfusion was received. 3. Absolute Neutrophil Count (ANC) of \<0.5 × 10\^9/L in at least 2 blood counts prior to randomization. 4. Platelet counts of \<50 × 10\^9/L in at least 2 blood counts prior to randomization. 3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. 4. Adequate organ function. 5. Women of child-bearing potential (according to recommendations of the Clinical Trial Facilitation Group \[CTFG\]) must not be pregnant or breastfeeding and must have a negative pregnancy test at screening. 6. Women of child-bearing potential must agree to use contraceptive measures of birth control for 6 months after completing treatment; men must use contraceptive measures and agree not to father a child for at least 3 months after completing treatment. Exclusion Criteria: 1. Treatment with any investigational drug or therapy within 2 weeks before study treatment. 2. Treatments for MDS must be concluded 1 month prior to study treatment. 3. Prior treatment with azacitidine, decitabine, or guadecitabine. 4. Diagnosis of chronic myelomonocytic leukemia (CMML). 5. Poor medical risk because of other conditions such as uncontrolled systemic diseases or active uncontrolled infections. 6. Prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, prostate cancer or breast cancer under control with hormone therapy, or other cancer from which the subject has been disease free for at least 1 year. 7. Known active infection with human immunodeficiency virus or hepatitis viruses.
