Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Bisantrene Dihydrochloride (high dose)
Treatment: Drugs - Bisantrene Dihydrochloride (low dose)
Treatment: Drugs - Cytarabine Hydrochloride
Treatment: Drugs - Decitabine and cedazuridine

Experimental: Stratum 1 - Bisantrene infused daily for 7 days of induction cycle 1; followed by bisantrene infusion on Days 1 and 2 and cytarabine arabinoside continuous infusion on Days 1 to 5 of each consolidation cycle for up to 3 cycles.

Each cycle is 28 days, with a potential to expand to 42 days to allow for full hematologic recovery.

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.


Treatment: Drugs: Bisantrene Dihydrochloride (high dose)
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

Treatment: Drugs: Bisantrene Dihydrochloride (low dose)
IV bisantrene at escalating doses for 3 dose levels of 50, 65, 85 mg/m2 on Days 3 and 5 until Maximum tolerated dose (MTD) reached.

Treatment: Drugs: Cytarabine Hydrochloride
Consolidation cycles: continuous IV cytarabine (100mg/m2) on Days 1 to 5

Treatment: Drugs: Decitabine and cedazuridine
PO fixed-dose decitabine/cedazuridine 35/100 mg tablet daily for 5 days (Days 1 to 5), 1 hour prior bisantrene infusion
