A Phase I/II Dose Escalation and Expansion Study of BST-236 Plus Venetoclax in Patients With Unfit Newly Diagnosed AML
Study Details
Study Description
Brief Summary
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

Experimental: Treatment BSR-236 + venetoclax |
Drug: BST-236
In part 1: During the induction (in combination with venetoclax), the BST-236 doses are:
In cohort 1 - 2.3 g/m2/d X6 days In cohort 2 - 2.3 g/m2/d X6 days In cohort 3 - 4.5 g/m2/d X6 days In cohort 4 - 4.5 g/m2/d X6 days In cohort 5 - 4.5 g/m2/d X6 days In part 1: During maintenances (for responding patients) the BST-236 dose- 4.5 g/m2/d X6 days In part 2, the dose chosen as safe and efficacious for induction in part 1 will be used
Drug: venetoclax
In part 1: During the induction (in combination with BST-236), the venetoclax doses are:
In cohort 1 - 200 mg QD X 7 days In cohort 2 - 400 mg QD X 7 days In cohort 3 - 200 mg QD X 7 days In cohort 4 - 400 mg QD X 7 days In cohort 5 - 200 mg QD X 14 days In part 2, the dose chosen as safe and efficacious for induction in part 1 will be used
