Eligibility Criteria
Inclusion
- Age ≥18 years
- Histologically confirmed Myelodysplastic Syndrome with positive TET2 mutations (We will test all MDS patients for TET2 mutations using next generation sequencing and only patients with TET2 mutations will be included in our study)
- Myeloblasts account for less than 20% of leukocytes on peripheral blood and bone marrow aspirate
- Eastern Cooperative Oncology Group (ECOG) performance status ≤2 (Appendix 1)
- Adequate organ function
- Platelets ≥20,000/μL
- Absolute neutrophil count ≥ 500/μL
- Bilirubin \< 1.5 x institutional upper limit of normal (ULN) or \< 3 x ULN in patients with Gilbert's disease or liver involvement
- Serum albumin ≥ 2.0 g/dL
- Aspartate aminotransferase (AST)/Alanine aminotransferase (ALT) ≤2.5 institutional ULN or, in the case of liver involvement by the primary disease AST/ALT ≤ 5 x ULN
- Creatinine≤1.5 x institutional ULN or estimated creatinine clearance of ≥45 mL/min by the Cockcroft-Gault equation or measured creatinine clearance \>45 mL/min
- Females of child bearing potential must have a negative serum pregnancy test with 7 days prior to first dose of treatment and use 2 methods of contraceptives while on treatment
- Ability to understand and the willingness to sign a written informed consent document
- Patients currently receiving or who previously received Hydroxyurea, Erythrocyte stimulating agents (ESA), or granulocyte colony stimulating factors (G-CSF) are allowed to participate in the study.
Exclusion
- Concurrent hypomethylation agent usage; the last dose of treatment must be ≥4 weeks before the start of the Vitamin C infusion
- Myeloblast count ≥20% in peripheral blood or bone marrow aspirate
- Major surgery within 2 weeks prior to first dose of study drug
- Allogeneic stem cell transplant
- Any previous chemotherapy agent other than hypomethylating agents (e.g., Venetoclax)
- Uncontrolled concurrent serious illness
- Concurrent malignancy or history of a previous malignancy within 1 year prior to first dose of the current study, unless curatively resected basal, squamous cell carcinoma of the skin, breast ductal/lobular carcinoma in situ or cervical carcinoma in situ.
- Active infections including hepatitis B carrier status, hepatitis C virus (HCV) infection (patients must have a negative Hep B and Hep C viral load at screening)
- Known HIV-positive status
- Any significant medical conditions, laboratory abnormality, or psychiatric illness that would exclude the subject from participation or interfere with study treatment, monitoring and compliance such as:
- Unstable angina pectoris, symptomatic congestive heart failure (NYHA III or IV), myocardial infarction ≤ 6 months prior to first study drug, clinically significant and uncontrolled cardiac arrhythmia (e.g. atrial fibrillation/flutter ventricular cardiovascular physiology is allowed), cerebrovascular accidents ≤ 6 months before study drug start
- Severely impaired lung function
- Serious, systemic infection requiring treatment ≤7 days before the first dose of study drug
- Any severe, uncontrolled disease or condition which in the investigator's opinion, may put the subject at significant risk, may confound the study results, or impact the subject's participation in the study
- History of any renal calculi or hyperoxaluria or any other preexisting renal disorder
- History of G6PD deficiency, hereditary spherocytosis or hemochromatosis
- Patients on therapeutic or prophylactic anticoagulation will be excluded from enrollment on the protocol. However, patients can remain on the study if they develop a thrombosis that requires therapeutic anticoagulation during the course of protocol therapy
- Uncontrolled hyponatremia, SIADH, hypokalemia, hyerpkalemia, hypomagnesemia or hypermagnesemia
