About this study

Official title: IDH2-Post-Allo-Trial: Enasidenib As Consolidation or Salvage Therapy for Patients with IDH2 Mutated AML or MDS Following Allogeneic Blood Stem Cell Transplantation

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Enasidenib in people with Leukemia, Myeloid, Acute and Myelodysplastic Syndromes, run by Heinrich-Heine University, Duesseldorf at 11 sites in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Type, incidence and severity of adverse events specifying seriousness and expectedness (AE, SAE, SUSAR) (time frame: through study completion, an average of 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024.
