A Study of Bisantrene Combined With Cytarabine or With Decitabine for Adult Subjects With Extramedullary AML and MDS (BISECT)

Study Overview
Status
Conditions
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.

Each cycle is 28 days, with a potential to expand to 42 days to allow for full hematologic recovery. |
Induction monotherapy cycle: IV bisantrene daily on Days 1 to 7, starting at 250 mg/m2 then adjusted to either 275 mg/m2 or 225 mg/m2 based on confirmed dose (Run-in) Consolidation combination cycle/s: IV bisantrene daily on Days 1 to 2

Experimental: Stratum 2
Decitabine/cedazuridine daily on Days 1-5, Bisantrene infusion on Days 3 and 5 in 28 day cycle. Treatment repeats every 28 days up to 12 cycles in the absence of disease progression or unacceptable toxicity. Each has potential to expand to 42 days to allow for full hematologic recovery. |
