Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Domain 3 is AMLM22/D3, will determine the safety and efficacy of AZD5153 and it will be conducted in two stages:
Stage 1: A safety run-in stage will confirm the planned optimal dose schedule. At least 9 and up to 18 patients will be enrolled in cohorts of 3 patients.

If initial dose level of AZD5153 is deemed intolerable, other dose levels will be explored. Decisions to escalate or de-escalate the dose and the identification of the optimal dose will be guided by use of a Bayesian Optimal Interval (BOIN) design.

Stage 2: Once the safety run-in phase is satisfactorily completed, patients will be randomised to either treatment arm 1:AZD5153 (casules; taken orally)at the identified optimal dose or treatment arm 2:standard of care (clinical observation) will commence.

Each treatment cycle will be 21days or 28days

Dose level +2
40 mg daily for 14 days of 21 day cycle or
40 mg daily for 14 days of 28 day cycle

Dose level +1
30 mg daily for 14 days of 21 day cycle or
30 mg daily for 14 days of 28 day cycle

Starting dose
20 mg daily for 14 days of 21 day cycle or
20 mg daily for 14 days of 28 day cycle

Dose level -1
15 mg daily for 14 days of 21 day cycle or
15 mg daily for 14 days of 28 day cycle

Dose level -2
10 mg daily for 14 days of 21 day cycle or
10 mg daily for 14 days of 28 day cycle

Dose level -3
5 mg twice daily for 14 days of 21 day cycle or
5 mg twice daily for 14 days of 28 day cycle

Treatment: Drugs
Comparator / control treatment
Patients that are randomised to treatment arm 2: standard of care, will receive standard of care treatment for AML remission, which is currently clinical observation. This is the care they would normally receive if they weren't on a trial.
Control group
Active

Outcomes
Primary outcome [1] 325432 0
Failure-free survival - this is the time from randomisation until the time of the earliest leukaemia event (relapse). Data to monitor failure-free survival (disease monitoring and MRD testing) will be collected from patient's at various protocol specified times points throughout the study.
Timepoint [1] 325432 0
Time from randomisation until the time of the earliest leukemia event- either MRD progression, MRD relapse, clinical relapse or death.
Secondary outcome [1] 387929 0
Safety (pilot phase)- Occurrence of related CTCAE grade 3-5 non-hematologic adverse events, related CTCAE grade 4-5 neutropenia or thrombocytopenia or grade 3-5 febrile neutropenia.
Timepoint [1] 387929 0
Analysis of these adverse events will be conducted on all patients in the safety set (defined as all patients in an experimental arm that received at least one dose of the study drug associated with that arm and all patients in the appropriate SoC control arm who did not receive a dose of a drug associated with a study arm in the relevant domain), in the first 6 months following randomisation.
Summary tables of newly emerging and worsening adverse events and laboratory tests (based on the worst CTCAE grade per patient), both severe (greater than or equal to Grade 3) and of any grade, will be reported by type, treatment arm and by cycles (for each of the first 6 cycles).

Summary
Brief summary
This study will evaluate the safety and efficacy of AZD5153 for Acute Myeloid Leukemia in the maintenance setting.

Who is it for?
You may be eligible to join this study if you are aged 16 and above and have Acute Myeloid Leukemia in first complete remission.

Study details
This study is part of the International AML Platform Consortium. Participants in this study will be randomly allocated (by chance) to one of two groups. Participants in one group will receive standard care which is generally observation. Participants in the other group will receive the drug AZD5153 daily for a total of upto 24 months.

As part of the study, participants will have blood tests at the start of each cycle (every 21 days) as well as an ECG to monitor heart function.
AZD5153 is known to have adverse effects on the heart therefore, participants will also have a MUGA (Multiple Gated Acquisition scan) at screening.
We hope that the results from this trial will be used to help these new treatments which may be better for people with AML than what is currently available ,become accessible to the general population at faster than the normal process.
