Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Domain 1 is AMLM22/D1, it has 2 treatment arms:
Arm 1: Molibresib (investigational product). Recommended dose of Molibresib is 40mg daily, taken orally on days 1-14 of each 28 day cycle. Total treatment duration is expected to be 24 months.
Arm 2: standard of care (generally observation)
Patients will be asked to return any unused molibresib tablets at each visit, for drug accountability
Intervention code [1] 313613 0
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 generally observation. This is the care they would normally receive if they weren't on a trial.
Control group
Active

Outcomes
Primary outcome [1] 319035 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] 319035 0
Time from randomisation until the time of the earliest leukemia event- either MRD progression, MRD relapse, clinical relapse or death.
Secondary outcome [1] 366765 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] 366765 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).
Secondary outcome [2] 366766 0
Overall survival
Timepoint [2] 366766 0
Overall survival from the date of randomisation until date of last contact including a sensitivity analysis on overall survival with additional censoring at the earlier of the date of additional or alternative therapy (including SCT).
Secondary outcome [3] 366767 0
Relapse free survival- Time from the date of randomisation to the date of relapse or death from any cause.
Relapse data will be collected from the patient and the patients hospital records.
Timepoint [3] 366767 0
Time from the date of randomisation to the earlier of the date of relapse or death from any cause, (censored and not censored for SCT).
Secondary outcome [4] 366768 0
MRD erasure -Eradication of MRD that was detected at screening in bone marrow or peripheral blood within 6 months of study randomisation. This will be assessed using flow cytometry and/or molecular methods (ie.quantitative PCR)
Timepoint [4] 366768 0
Eradication of MRD detected at screening within 6 months of study randomisation
Secondary outcome [5] 366769 0
Quality of life
Timepoint [5] 366769 0
The FACIT-Fatigue Scale and the EQ-5D score at baseline, 6, 12, 18 and 24 months

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will occur by a central randomization procedure, in a 2-step process.
Participants will first be randomised to an eligible domain based on physical and disease characteristics. They will then be randomised to a treatment arm within that domain.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation
Masking / blinding
Open (masking not used)
