Linked study record
ACTRN12621000439842 is the AMLM26 Intercept Master Protocol. The AMLM26 Intercept trial is a platform trial investigating many new investigational agents and combinations for AML patients with rising measurable residual disease (MRD) or early morphologic relapse. The treatment arm described in this registration form is for one treatment arm included on the platform - LDAC + Venetoclax

Description of intervention(s) / exposure
The ALLG AMLM26 INTERCEPT trial is an adaptive trial allowing the testing of multiple new therapeutic options targeting various AML biomarkers in a staged manner. The Master Protocol outlines the overall study structure (this is detailed in ANZCTR entry ACTRN12621000439842). There will be separate domains for each AML biomarker being investigated. Each domain will have at least one investigational agent. Each investigational agent may be used on its own and/or in combination with other agents. Each option will be a different treatment arm within a domain. Separate Therapy-Specific Protocol Appendices will include treatment-specific information for each investigational agent including all of the treatment arms specific to that investigational agent. Each treatment arm may be targeted to a specific AML biomarker (domain) and/or may be used when patients have no targetable option available. This entry is for the treatment arm LDAC + Venetoclax.

Each cycle will be 28-days in length. Venetoclax will be administered orally once daily Days 1–28, of a 28-day cycle for 12 cycles, with a designated dose of 600 mg daily. Please note that Venetoclax dose ramp-up is required only for patients commencing therapy with bone marrow blasts of greater than or equal to 5%: 100 mg on day 1, 200 mg on day 2, 400 mg on day 3 and 600 mg on day 4 onwards. LDAC (20 mg/m2) is administered subcutaneously once daily following administration of Venetoclax on Days 1-10 of every cycle.

Patients will be asked to complete a dose diary to confirm the tablets were taken. Patients will also be asked to return the LDAC and Venetoclax bottles (with unused tablets or empty containers) to the hospital. This is to monitor compliance with the treatment.

Outcomes
Primary outcome [1] 336439 0
To determine the MRD response of patients with NPM1 mutated AML in the MRD failure stratum to their first-exposure to decision rule guided therapy with LDAC + Venetoclax.
Timepoint [1] 336439 0
The primary endpoint is MRD response within 100 days of Cycle 1 Day 1. MRD response is defined as a reduction of greater than or equal to 1-log in the molecular marker, and/or MRD negativity, or less than 0.1% aberrant disease by flow cytometry
Secondary outcome [1] 428549 0
To determine the durability of the response of AML patients to LDAC + Venetoclax
Timepoint [1] 428549 0
Relapse-free survival (RFS): Measured from the date of molecular response to the earlier of the date of progression or the date of death without prior progression. MRD response is defined as a reduction of greater than or equal to 1-log in the molecular marker, and/or MRD negativity, or less than 0.1% aberrant disease by flow cytometry. This is measured by bone marrow and blood samples. Your disease will continue to be followed until the study is completed (this may be for longer than 5years).
Secondary outcome [2] 428550 0
To investigate the dynamics of MRD response and the duration of clinical benefit as a composite outcome in the morphologic and MRD failure strata
Timepoint [2] 428550 0
Time to MRD response will be assessed at end of cycle 1,2,3, and 12, end of months 18 and 24 post treatment commencement.
Secondary outcome [3] 428552 0
To investigate duration of MRD response in patients treated at MRD failure versus morphologic relapse.
Timepoint [3] 428552 0
Duration of MRD response measured from the date of MRD response to the earliest date of MRD failure or the date of death without prior progression
Secondary outcome [4] 428553 0
To investigate the efficacy of distinct treatment sequences in AML patients who fail one or more lines of therapy on study.
Timepoint [4] 428553 0
For each patient, relapse-free periods will be calculated using the same definitions of response and relapse as for the primary and key-secondary endpoints. Patients will continue to have their disease status followed until the end of the trial, (this may be for longer than 5 years)
Secondary outcome [5] 428554 0
To determine the overall efficacy of the platform as an evolving system for managing patients with AML
Timepoint [5] 428554 0
Overall survival as measured from the date of first dose of study drug until the date of last contact or death. Patients will continue to have their survival status followed until the end of the trial under the Master Protocol
Secondary outcome [6] 428555 0
Quality of Life will be measured as a composite outcome via the use of 2 quality of life tools.
Timepoint [6] 428555 0
Quality of Life (QoL) measured using QLQ-C30 & EQ-5D Day 1 of cycle 1, day 1 of cycle 2 and day 1 of cycle 3.
