You may be eligible if
Age ≥18 years at the time of signing the informed consent form.
Willing and able to adhere to the study visit schedule and other protocol requirements.
Unexplained cytopenia for at least 6 months. Cytopenia is defined as the presence of ≥1 blood count indexes below the following thresholds:
Hgb \<10 g/dL
ANC \<1.8 × 10\^9/L
Platelets \<100 × 10\^9/L
Results of bone marrow biopsy within 1 month of study entry (screening bone marrow biopsy) must not indicate hematologic disease.
IDH2 gene mutation (R140 or R172), performed locally, at a frequency \>2%.
ECOG performance status of 0-2.
Adequate organ function, defined as:
* Serum aspartate aminotransferase/serum glutamic oxaloacetic transaminase (AST/SGOT) and alanine aminotransferase (ALT/SGPT) ≤3x upper limit of normal (ULN), unless the subject has Gilbert's syndrome.
* Serum total bilirubin \<1.5x ULN. Higher levels are acceptable if these can be attributed to ineffective erythropoiesis. In these cases, approval from the study Principal Investigator is required.
* Creatinine clearance greater than 50 mL/min based on the Cockroft-Gault glomerular filtration rate estimation.
Women of childbearing potential may participate provided they have a negative serum pregnancy test at screening and a negative serum or urine pregnancy test within 72 h of starting treatment.
Women of childbearing potential (WOCBP) and males with partners who are WOCBP must agree to abstain from sexual intercourse or to use 1 highly effective form of contraception during the study and for at least 4 months following the last dose of enasidenib. Males with partners who are WOCBP must agree to use a barrier method.
You may not be if
Active malignancy defined as \>1-cm disease on most recent CT scan in the past 6 months or recent history of cancer (i.e. within the past 5 years) with \>50% chance of cancer recurrence in the next 5 years.
Current or prior history of hematologic malignancy.
Therapy (including maintenance therapy) for solid-tumor malignancy within the last 6 months.
Known dysphagia, short-gut syndrome, gastroparesis, or other conditions that limit the ingestion or gastrointestinal absorption of drugs administered orally.
Active uncontrolled systemic fungal, bacterial, or viral infection (defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment).
Positive direct Coombs test
Evidence of hypersplenism on physical exam
Pregnant or lactating (women).
