A Phase I/II Dose Escalation and Expansion Study of BST-236 Plus Venetoclax in Patients With Newly Diagnosed Acute Myeloid Leukemia Unfit for Intensive Induction Chemotherapy

Description

An open label multi centre study to assess the safety and efficacy of BST-236 in combination with venetoclax in adult patients unfit for standard therapy with newly diagnosed Acute Myeloid Leukemia (AML) Part 1 of the study will define the maximal tolerate dose of the combination treatment, while part 2 will expend the chosen dose, to assesses efficacy and safety of this combination. All patients will receive 2 induction courses with both BST-236 and venetoclax, responding patients will then be followed with up to 3 maintenance courses with BST-236 alone. Patients will be followed for 1 year in the study and additional 1 year in post study follow-up

Unstable angina, significant cardiac arrhythmia, or New York Heart Association (NYHA) Class IV CHF 16. History of allergic reactions attributed to compounds of similar chemical composition as BST-236 and/or cytarabine and/or venetoclax. 17. Surgical procedure, excluding central venous catheter placement or other minor procedures (e.g. skin biopsy) in the 14 days prior to enrollment
