About this trial

The goal of this observational study is to develop new ways to test new drug combinations to kill tumour cells, in patients with acute myeloid leukemia (AML). The main questions it aims to answer are:

* Are there new ways to speed up discovery of better treatments for AML patients using AML cells from individual from patients in special mice that can accept human tissue? * Do these mice show treatment responses that are similar to the individual AML patient from whom cells were derived?

Participants with AML who are taking standard of care treatment of venetoclax and azacitidine will be asked to donate blood and bone marrow samples for this study.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age 18 years and above

Patients with suspicion of AML requiring screening procedures

Documented diagnosis of AML by WHO Classification and/or International Consensus Classification.

Regardless of the number and type of prior lines of therapy or eligibility for allogeneic stem cell transplantation.

Disqualifiers

None

Trial population

Study population is people who have recently been diagnosed with or are suspected of having AML and undergoing investigational procedures, and whose doctor plans to start them on venetoclax and azacitidine. Around 25 people from different hospitals in Australia will take part in this project.

Trial outcomes

Primary outcomes

1

Primary Endpoint - Generation of ≥20 adult AML PDX models with clinically annotated samples, including treatment regimen and clinical outcome

The outcome measures are 1) establish an adult AML PDX drug testing platform; 2) determine how accurately the AML PDX model replicates the clonal architecture and cellular characteristics of the original tumour by comparing donors' samples to AML PDX samples; 3) compare efficacy of standard of care and candidate therapies by engrafting multiple immune-deficient mice with the same donor sample; and 4) biomarker discovery through correlation of treatment response and single-cell and cytokine analysis.

Time frame
From enrolment (i.e., C1D1 of Ven+AZA treatment) up to end of treatment or 52 weeks post C1D1 (whichever applies first)

Secondary outcomes

1

Secondary Endpoint - Frequency and phenotype of leukemic cells measured by flow cytometry in AML PDX models and primary donor samples before and after VEN+AZA treatment.

A) Peripheral blood and bone marrow samples will be collected from Cohort 1 and Cohort 2 participants at baseline and relapse and will undergo molecular and cellular characterisation, these samples will be used to generate AML PDX models. B) Cells isolated from participant samples will be used to generate adult AML PDX models by reconstituting immune-deficient mice and expand the cell stock in vivo. Expanded cells will be used to reconstitute additional immune-deficient mice. C) Samples will be collected from immune-deficient mice before and after treatment to assess the efficacy of individual treatments. Participant and PDX samples will also be compared to assess the fidelity of the PDX model to their matching donor.

Time frame
From enrolment (i.e., C1D1 of Ven+AZA treatment) up to end of treatment or 52 weeks post C1D1 (whichever applies first)
