Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Azacitidine + Ascorbic acid

Arm Description

Azacitidine will be administered intravenously or subcutaneously at a fixed dose of 75mg/m2/day for 7 consecutive days, (allowing for weekends, and holidays) of each 28-day cycle.

Outcomes

Primary Outcome Measures

Number of patients with response per MDS International Working Group 2006 Criteria
A binary indicator of overall response, defined as achieving CR, PR, or HI) per 2006 International Working Group (IWG) criteria Responses for MDS patients: Complete Response (CR): Bone marrow: ≤ 5% myeloblasts with normal maturation. Peripheral blood: Hgb ≥ 11 g/dL Platelets ≥ 100 × 109/L Neutrophils ≥ 1.0 × 109/L, Blasts 0% Partial response (PR): All CR criteria if abnormal before treatment except: bone marrow blasts decreased by ≥ 50% over pretreatment but still > 5% Hematologic Improvement (HI): (responses must last at least 8 weeks) Erythroid response [HI-E; (if pretreatment Hgb < 11 g/dL)]; Hgb increase by ≥ 1.5 g/dL; Relevant reduction of units of red blood cell (RBC) transfusions by an absolute number of at least 4 RBC transfusions/8 weeks compared with the pretreatment transfusion number in the previous 8 weeks. Only RBC transfusions given for an Hgb of ≤ 9.0 g/dL pretreatment will count in the RBC transfusion response evaluation.
Number of AML patients with response
Complete Response (CR): Bone marrow: ≤ 5% myeloblasts with normal maturation of all cell lines, Absolute neutrophil count (ANC) >/= 1.0 X 109/L, platelet count >/= 100 X 109/L, no detectable Auer rods and no extramedulary leukemia. Complete Response (CR) with incomplete hematologic recovery (CRi): Responses as in CR but ANC < 1.0 X 109/L. Complete Response (CR) with incomplete platelets recovery (CRp): Responses as in CR but platelets < 100 X 109/L. Partial response (PR): All CR criteria if abnormal before treatment except: bone marrow blasts decreased by ≥ 50% over pretreatment but still > 5%.

Secondary Outcome Measures

Incidence of adverse events
Incidence of adverse events of the combination defined by CTCAE 4.1 criteria. Toxicity will be any drug related Grade 3 or 4 toxicity.
Response duration
Response duration to the combination recorded from start of treatment to progression
Overall survival
Overall survival measured from start of treatment to death or last follow up

5. Study Description

Brief Summary
The purpose of this study is to evaluate the efficacy of treatment with azacitidine (an FDA approved drug for the treatment of MDS) and high dose ascorbic acid in patients with TET2 mutations. This approach is intended to enhance the enzymatic activity of TET2 protein, which in term may help to improve counts and symptoms, related to Myelodysplastic Syndromes and Acute Myeloid Leukemia. This combination is specific to individuals who carry this mutation.
Detailed Description
Primary Endpoint To estimate the overall response rate (ORR) of the combination of standard dose azacitidine and oral dose of ascorbic acid in patients with MDS, AML, and MDS / Myeloproliferative Neoplasm (MPN) overlap with heterozygous TET2 mutations Secondary Endpoints The safety profile of the combination in the targeted patient population Response duration Overall survival of the treated population (compared to matched historical cohort of patients treated with single agent Azacitidine) The identification of biomarkers that predict response to the combination Study Design This is an open-label, phase II study that will be conducted at Cleveland Clinic, Taussig Cancer Institute. Azacitidine will be administered intravenously or subcutaneously at a fixed dose of 75mg/m2/day for 7 consecutive days, (allowing for weekends, and holidays) of each 28-day cycle. Ascorbic acid will be administered orally daily at 1 g/day three days prior to start azacitidine and then continues daily for a total of 28 days of each 28 day cycle.
