Description
Inclusion Criteria:
Documented diagnosis of
- MDS according to WHO/FAB classification that meets IRSS-R classification of low or intermediate risk disease; and a diagnosed as denovo or secondary MDS (MDS-RS eligible if refractory to or declined luspatercept therapy) OR

Has symptomatic anemia defined as hemoglobin < 10.5 g/dL with any of the following.
- Tachypnea
- Shortness of breath
- Fatigue
- Malaise
- Worsening of cardiovascular function
- Asthenia
- Dyspnea on exertion
- Angina
- Other subject symptoms the subject reports as being associated with being anemic.
- Stated willingness to comply with all study procedures and availability for the duration of the study
- Ability to take oral medication and be willing to adhere to the medication regimen.
- Females of reproductive potential need to either commit to true abstinence from heterosexual contact or agree to use, and be able to comply with highly effective contraception without interruption, 28 days prior to starting enasidenib, during the study therapy, and for 30 days after last dose of enasidenib
- For males of reproductive potential: agreement to use of condoms
Adequate organ function defined as:
- Hepatic function: total bilirubin <1.5 x ULN (unless attributable to Gilbert's disease), AST or ALT < 3x ULN
- Renal function: creatinine clearance > 30 mL/minute, calculated by Cockcroft-Gault formula
- Ability to understand and the willingness to sign the IRB approved informed consent document.
- Women of childbearing potential must have negative urine or serum pregnancy test
Exclusion Criteria:
- Use of concurrent other erythropoietic agents (including epoetin, darbepoetin), G-CSF within 30 days of study enrollment

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Clinical Response: Hematological Improvement - Erythroid (HI-E)
Time Frame: 16 weeks
|
Clinical response was assessed as the number of participants achieving a hematological improvement - erythroid (HI-E). Participants will be characterized and stratified as nontransfused (NTD), low-transfusion burden (LTB) and high-transfusion burden (HTB), with response defined as follows.
|
16 weeks
|
Related Adverse Events
Time Frame: 12 months
|
Toxicity will be assessed as the number of related non serious adverse events and related serious adverse events (SAEs) reported for the 12 cycle treatment period plus follow up.
The outcome will be reported as numbers without dispersion.
|
12 months
|
Time to Hematological Improvement - Erythroid (HI-E)
Time Frame: 16 weeks.
|
Time to hematological improvement - erythroid (HI-E) will be assessed as the time from first dose of enasidenib to the first observed hemoglobin response. Participants will be characterized and stratified as nontransfused (NTD), low-transfusion burden (LTB) and high-transfusion burden (HTB), with response defined as follows.
|
16 weeks.
|
Duration of Hematological Improvement - Erythroid (HI-E)
Time Frame: 16 weeks.
|
Duration of Hematological Improvement - Erythroid (HI-E) will be assessed as the time from recorded response to loss of response. Participants will be characterized and stratified as nontransfused (NTD), low-transfusion burden (LTB) and high-transfusion burden (HTB), with response defined as follows.
|
16 weeks.
|
Clinical Response: Hematological Improvement - Platelets (HI-P)
Time Frame: 8 weeks
|
Clinical response for platelets was assessed as the number of participants achieving a hematological improvement - platelets (HI-P). Participants will be characterized and stratified as platelets < or ≥ 20 x 10^9/L, with response defined as follows.
|
8 weeks
|
Clinical Response: Hematological Improvement - Neutrophils (HI-N)
Time Frame: 8 weeks
|
Clinical response for neutrophils was assessed as the number of participants achieving a hematological improvement - neutrophils (HI-N). Response defined as an absolute increase in neutrophils > 0.5 x 10^9/L that is also an increase of ≥ 100%. The outcome will be reported as the number of participants that achieve the response, a number without dispersion. |
8 weeks
|
Red Blood Cell (RBC) transfusion independence (RBC TI)
Time Frame: 12 months
|
Clinical response for red blood cells was assessed as the number of participants who were transfusion dependent that achieve red blood cell (RBC) transfusion independence (RBC TI) for for 8 weeks or longer.
The outcome will be reported as the number of participants that achieve the response, a number without dispersion.
|
12 months
