Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Elacytarabine continous infusion days 1-5, every 3 weeks,
dose 2000 mg/m2/d.
1-2 treatment courses should be administered for remission induction, and 1-2 courses for consolidation. Patients who benefit from the treatment may receive repeated courses
of study drug at the discretion of the investigator, even if remission is not attained.
Intervention code [1] 258018 0
Treatment: Drugs
Comparator / control treatment
Investigator choice: One of the listed treatments must be selected prior to randomization: The formulation and dose will be at the discreation at the investigator / according to local standards and availibility
*Cytarabine at doses 1-6 g/m2/d, for up to 6 days, but with a maximum total dose; of 36 g/m2 per course (intravenous adm)
*Mitoxantrone + etoposide + cytarabine (MEC) (intravenous adm)
*Fludarabine + cytarabine + G-CSF +/- idarubicin (FLAG/FLAG-IDA) (intravenous adm):
*low-dose cytarabine; (intravenous adm maximum 20 mg/m2/d)
*hypomethylating agents (e.g. decitabine, azacitidine)(intravenous adm):
*Hydroxyurea with the intent to control the white blood cell count (WBC), (oral adm):
*Palliative care: Drugs / dose / adm at the discretion of the investigator

Outcomes
Primary outcome [1] 262114 0
Compare the efficacy, measured as overall survival (OS), of elacytarabine and
investigator's choice in patients with late stage AML
Timepoint [1] 262114 0
Up to 6 months after last patient included in the trial.
Secondary outcome [1] 273189 0
Compare response rate and duration of response of elacytarabine and investigator's
choice in patients with late stage AML.
Remission rate measured by overall response rate (ORR); i.e. complete remission(CR) and complete remission with incomplete bone marrow recovery (CRi), Remission rate measured by CR, Remission duration analysed using cumulative incidence of relapse (CIR) measured
from date of CR or CRi
Timepoint [1] 273189 0
After completion of treatment according to protocol: Normally after 1-2 cycles of elacytarabine, for Investigator Choice Arm depending on type of control treatment selected
Secondary outcome [2] 273190 0
Compare the safety profile of elacytarabine with investigator's choice by assessing clinical and laboratory adverse events (AEs), and deaths.
Expected adverse events for elacytarabine is for example reduced blood counts, gastrointestinal ecents (diahorrea, constipation), fever, headache, elevated liver function tests
Timepoint [2] 273190 0
Up to 30 days after the last dose of study drug
Secondary outcome [3] 273191 0
Characterize exposure-response relationships for measures of effectiveness and toxicity by correlateing PK profiles with response and toxicity (for elacytarabine treated pateints only)
Timepoint [3] 273191 0
During and up to 48 hours after the first course of elacytarabine continous infusion

Eligibility
Key inclusion criteria
- Patients with a confirmed diagnosis of AML according to WHO classification
(excluding acute promyelocytic leukaemia) who have received two or three
previous induction/re-induction regimens. One of the (re-)induction regimens could
be stem cell transplantation (SCT) for achievement of remission. Maintenance and
consolidation (including SCT) may have been given, but are not counted as
previous regimens.
- Patient’s bone marrow aspirates and/or biopsies must contain > 5 % leukaemic
blast cells or patient must have biopsy-proven extramedullary AML, or patient’s
peripheral blood shows occurrence of leukaemic blast cells
- Patients must
a. have never attained CR or CRi (primary refractory), or
b. have failed initial induction therapy, and have attained CR or CRi after
salvage therapy(ies), and then relapsed within < 6 months, or
c. have attained CR or CRi after initial induction therapy and relapsed within
<12 months, and failed to respond to salvage therapy(ies), or
d. have relapsed after the latest CR or CRi within < 6 months
- Patients younger than 65 years should have received previous treatment with
cytarabine
- Patients must have recovered from previous bone marrow and/or stem cell
transplantation to a stage that the patient can tolerate the study treatment. There is
no restriction on number of regimens or type of treatment administered for
maintenance or consolidation during previous stages of the disease
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
-Persistent clinically significant toxicities from previous chemotherapy
-Impairment of hepatic or renal function to such an extent that the patient, in the opinion of the investigator, will be exposed to an excessive risk if entered into this
clinical study
- Active heart disease including myocardial infarction within previous 3 months,
symptomatic coronary artery disease, arrhythmias not controlled by medication, or
uncontrolled congestive heart failure. Any NYHA grade 3 or 4.
- Patients receiving any anti-leukaemic agents within the last 4 weeks. Hydroxyurea, however, is allowed for up to 12 hours prior to study treatment.
- Patients receiving any investigational treatment within the last 14 days
