About this study
Official title: An Open-label Two Strata Study of Bisantrene in Combination With Cytarabine Arabinoside or Bisantrene in Combination With Oral Decitabine/Cedazuridine for the Treatment of Acute Myeloid Leukemia Patients With Extramedullary Disease
This is a two strata Phase 1b study to assess the safety and efficacy of bisantrene (RC110) in combination with a) cytarabine arabinoside (Ara-C) treatment for patients with relapsed or refractory (R/R) Acute Myeloid Leukemia (AML) with extramedullary disease and able to tolerate intensive chemotherapy; b) in combination with decitabine/cedazuridune (ASTX727) new or relapsed or refractory AML or high risk MDS or CMML with extramedullary disease and unable or not willing to have intensive chemotherapy.
Read the detailed description
The study is a multicenter, open label in patients with haematological malignancy / myeloproliferative disease (AML, MDS and CMML) and extramedullary disease (EMD) investigating 2 treatment regimens:
- Stratum 1 will investigate use of high dose intravenous (IV) bisantrene (RC110) in combination with IV Ara-C for R/R AML with EMD able to tolerate intensive chemotherapy. This includes a run-in stage to confirm the dose of bisantrene (RC110) for induction and in combination with Ara-C for consolidation cycles and an expansion and an expansion stage that will treat additional patients at the confirmed bisantrene dose for induction and in combination with Ara-C consolidation cycles;
- Stratum 2 will investigate use lower doses intravenous (IV) bisantrene (RC-110) in combination with fixed-dose oral decitabine/cedazuridine (ASTX727) to determine the maximum tolerated dose (MTD) for new or R/R AML and HR-MDS/CMML unable to tolerate intensive chemotherapy.
Pre-screening will be conducted to identify patients with EMD diagnosed by standard clinical practice including histology and by fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F FDG-PET/CT) imaging.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a two strata Phase 1b study to assess the safety and efficacy of bisantrene (RC110) in combination with a) cytarabine arabinoside (Ara-C) treatment for patients with relapsed or refractory (R/R) Acute Myeloid Leukemia (AML) with extramedullary disease and able to tolerate intensive chemotherapy; b) in combination with decitabine/cedazuridune (ASTX727) new or relapsed or refractory AML or high risk MDS or CMML with extramedullary disease and unable or not willing to have intensive chemotherapy.
Detailed description
The study is a multicenter, open label in patients with haematological malignancy / myeloproliferative disease (AML, MDS and CMML) and extramedullary disease (EMD) investigating 2 treatment regimens:
- Stratum 1 will investigate use of high dose intravenous (IV) bisantrene (RC110) in combination with IV Ara-C for R/R AML with EMD able to tolerate intensive chemotherapy. This includes a run-in stage to confirm the dose of bisantrene (RC110) for induction and in combination with Ara-C for consolidation cycles and an expansion and an expansion stage that will treat additional patients at the confirmed bisantrene dose for induction and in combination with Ara-C consolidation cycles;
- Stratum 2 will investigate use lower doses intravenous (IV) bisantrene (RC-110) in combination with fixed-dose oral decitabine/cedazuridine (ASTX727) to determine the maximum tolerated dose (MTD) for new or R/R AML and HR-MDS/CMML unable to tolerate intensive chemotherapy.
Pre-screening will be conducted to identify patients with EMD diagnosed by standard clinical practice including histology and by fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F FDG-PET/CT) imaging.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Bisantrene Dihydrochloride (high dose), Bisantrene Dihydrochloride (low dose) and Cytarabine Hydrochloride in people with Acute Myeloid Leukemia and Recurrent Acute Myeloid Leukemia, run by Racura Oncology Ltd at 1 site in Australia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 3 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Stratum 1, Stage 1: Dose confirmation (time frame: 8 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Oct 2023.
