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.

Study type
Interventional
Description of intervention(s) / exposure
AMLM28 ADAPT-STOP domain aims to address the question of whether it is safe to stop therapy in patients responding well to venetoclax and Azacitidine (VEN-AZA) therapy.

All patients in the ADAPT Master trial (ACTRN12623000900617) that achieve Complete Remission (CR), CR with incomplete haematologic recovery (CRi) or CR with partial haematologic recovery (CRh) with undetectable Measurable Residual Disease (MRD) by 12 months (plus or minus 14 days) (from Cycle 1 Day 1) will be eligible to enter the ADAPT-STOP domain. These patients and their site investigators will have a choice between continuing therapy or electively ceasing therapy.
-Patients who continue therapy will remain on the ADAPT Master protocol.
-Patients who chose to electively cease therapy will be eligible to enter the ADAPT-STOP domain and will be randomised in a 1:1 ratio to the following:
o Ceasing therapy at 12-14 months (immediate-stop)
o Ceasing therapy at 18-20 months (delayed-stop)
-Following therapy cessation, central MRD will be monitored 3-monthly in the first 12 months followed by 6 monthly for the next 12 months. Monitoring will involve attending an appointment with their oncologist for a bone marrow aspirate (BMA) collection for flow cytometry MRD analysis, as well as blood tests.
-Patients will be followed-up for 3 years on the ADAPT-STOP domain and at least up to 5 years (6 monthly sweeps for overall survival and disease status via participation in the ALLG’s National Blood Cancer Registry (NBCR)).
-Patients experiencing morphological or MRD relapse may be enrolled to the ALLG AMLM26 INTERCEPT (ACTRN12621000439842) study if eligible and study is available at any time during a monitoring visit post-cessation, from 3 months post-cessation.

All treatment will be administered or ceased (for patients enrolled in the STOP domain) by the study team. Drug accountability will be performed by the administering institutions to assess compliance.

Outcomes
Primary outcome [1] 336700 0
Comparison of Relapse-free survival (RFS) in patient groups continuing VEN-AZA vs. groups early stopping of VEN-AZA.
Timepoint [1] 336700 0
At 6 months from the date of randomisation.
Primary outcome [2] 336701 0
To determine the percentage of patients alive and in sustained CR/CRi/CRh with MRD negativity (less than 0.1percent) after elective therapy cessation post at least 12 months of Venetoclax-Azacitidine (VEN-AZA) therapy.
Timepoint [2] 336701 0
At three pre-defined landmarks: 12, 24 and 36 months from the date of stopping (defined as date of last dose of venetoclax and/or azacitidine (whichever comes later)).
Secondary outcome [1] 429365 0
To determine the duration of time remaining in MRD negative remission without ongoing therapy after elective therapy cessation whilst in CR/CRi/CRh with MRD negativity after at least 12 months of VEN-AZA therapy.
Timepoint [1] 429365 0
Additional analysis adjusted for a landmark at 6 months from randomisation will be performed.
Secondary outcome [2] 429366 0
Overall survival (OS)
Timepoint [2] 429366 0
Overall survival measured from day 1 of VEN-AZA therapy to the date of death from any cause assessed continuously from enrolment until completion of trial (maximum 7 years).
Secondary outcome [3] 429367 0
Relapse free survival (RFS)
Timepoint [3] 429367 0
Assessed continuously from date of remission (CR/CRi/CRh on VEN-AZA therapy) until the completion of the trial.
Secondary outcome [4] 429368 0
Quality of life and fear of cancer recurrence assessments (assessed as a composite secondary outcome)
Timepoint [4] 429368 0
Every 3 months for the first 12 months, then 6 monthly for the next 12 months since entry into ADAPT-STOP.

Eligibility
Key inclusion criteria
ADAPT Master Protocol (ACTRN12623000900617):

3. Undetectable MRD after 12 months (plus or minus 14 days) from starting VEN-AZA therapy.
a. Undetectable MRD is defined as either less than or equal to 0.1percent by flow cytometry and/or molecular MRD (for validated molecular markers [NPM1, RUNX1::RUNX1T1, CBFB::MYH11, KMT2Ar] with a limit of detection of at least 0.01%)
b. Two consecutive measurements of undetectable MRD performed at least 28 days apart will be required
