Detailed Description
This is a prospective, open label, single arm, multi-centre phase II trial aiming to evaluate the safety and efficacy of Enasidenib (investigational product) as prophylactic consolidation in patients with IDH2-mutated MDS, CMML and AML in remission after allo-SCT.
Study Design:
- interventional
- prospective, open-label, single arm, multicenter phase-II trial
- total patients sample size: 50 patients
- number of trial sites: 11 all located in Germany and members of the EBMT
Patients with AML, MDS and CMML, in whom an IDH2 mutation has been detected at diagnosis prior allo-SCT, are eligible for consolidation therapy, if they are in complete hematological remission after first allo-SCT. IDH2 mutation might be absent at this time (CRMRDnegative), or might be detectable at submicroscopical levels (CRMRDpositive) given the high sensitivity of detection methods nowadays available. Remission will be evaluated within a screening period between day +25 and day +35. Evaluation of remission will be performed locally with IDH2 mutation analysis performed at an experienced local laboratory of the respective center. The report about IDH2 mutation testing at diagnosis has to be sent to the principle investigator for review at screening to include the patient; a BM sample will be stored for central retesting, which will be performed in batch during the course of the study. Having a documented hematological CR, patients will enter the treatment phase within 30 days after this BM evaluation (latest time point day +65) and start treatment with Enasidenib. They are envisaged to receive Enasidenib (100 mg per day, day 1-28) for up to 12 cycles (=12 months). Patients will go off protocol prematurely in case of relapse, intolerability of study treatment and in case of withdrawal of consent. In those patients who relapse during study treatment subsequent therapy for relapse will be performed according to the choice of the individual treating physician. Patients who finish study as planned or prematurely will be regularly followed for one year, lost to follow up, death or withdrawal of consent.

Eligibility Criteria
Ages Eligible for Study

Description
Inclusion Criteria:
- Patients with myeloid malignancy (AML, MDS and CMML) and known IDH2 mutation (IDH2 R172 or R140 mutation) at diagnosis prior to first allo-SCT
- hematological CR after allo-SCT determined during screening period between day +25 and day +35 (the hematological remission will be confirmed locally by cytomorphological/histological evaluation)
- Hematopoietic recovery after transplantation indicated by an absolute neutrophil count of at least 1.000/µl and platelet count of at least 50.000/µl
- no previous therapy with Enasidenib or any other IDH2 inhibitor
- ECOG performance status ≤ 2 at study entry (s. Appendix)
- no active, steroid refractory GvHD treated with additional systemic immunosuppression within 4 weeks before inclusion
- no uncontrolled infection at inclusion
- Understand and voluntarily sign an informed consent form.
- Age ≥18 years at the time of signing the informed consent form.
- Able to adhere to the study visit schedule and other protocol requirements.
- Female of childbearing potential (FCBP) must:
Understand that Enasidenib can cause embryo-fetal harm when administered to a pregnant woman Agree to have a medically supervised pregnancy test within 72 hours prior study start and at day 1 of every treatment cycle Use effective contraception during treatment with Enasidenib and for at least 2 months after the last dose Coadministration of Enasidenib may increase or decrease the concentrations of combined hormonal contraceptives Avoid becoming pregnant while receiving Enasidenib Notify her study doctor immediately if there is a risk of pregnancy Agree to abstain from breastfeeding during study participation and for at least 30 days after study drug discontinuation Understand that Enasidenib may impair fertility in females of reproductive potential and this effect may be not reversible
- Males must: Understand that Enasidenib can cause embryo-fetal harm Use effective contraception during treatment with Enasidenib and for at least 2 months after the last dose of Enasidenib if engaged in sexual activity with a pregnant female or a female with childbearing potential Agree to notify the investigator immediately, if pregnancy or a positive pregnancy test occurs in his partner during study participation Understand that Enasidenib may impair fertility in males of reproductive potential and this effect may be not reversible
Exclusion Criteria:

- Any previous prophylactic therapy given within the interval between allo-SCT and screening period
- Patients with myeloid malignancy (AML, MDS and CMML) and known IDH2 mutation (IDH2 R172 or R140 mutation) after second allo-SCT
- Active, steroid refractory GvHD treated with additional systemic immunosuppression within the last 4 weeks
- Uncontrolled infection
- Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
- Pregnant or lactating females
- Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study
