5. Study Description

Brief Summary
This is a Phase 1, open-label, single center study of short-course oral venetoclax therapy prior to non-myeloablative conditioning with fludarabine and cyclophosphamide in subjects with haematological malignancies who are planned for allogeneic stem cell transplantation (alloSCT). The primary study objective is to determine the safety and maximum tolerated dose of venetoclax when used in combination with fludarabine and cyclophosphamide conditioning. Secondary objectives were to evaluate the transplant outcomes and donor/recipient engraftment of this regimen.
Detailed Description
Eligible patients are to be enrolled sequentially into one of 4 treatment Dose Levels (beginning with Dose Level A) to receive short-course venetoclax on day -11 to -6, followed by intravenous fludarabine 30mg/m2 daily (day -5 to -3) and intravenous cyclophosphamide 750mg/m2 daily (day -5 to -3). Allogeneic stem cell infusion will occur on day 0. In the dose-escalation phase of this 3+3 study, three patients are planned for each Dose Level. Dose Level A: venetoclax 100mg daily administered on day -11 to -6 (total venetoclax dose: 600mg) Dose Level B: venetoclax 100mg daily administered on day -11, followed by 200mg daily administered on day -10 to -6 (total venetoclax dose: 1100mg) Dose Level C: venetoclax 100mg daily administered on day -11, followed by 200mg daily administered on day -10, 400mg daily administered on day -9 and 600mg daily administered on day -8 to -6 (total venetoclax dose: 2500mg) Protocol-specific dose-limiting toxicitues (DLTs) will be assessed from the first dose of venetoclax up to day 30 post-transplant. Subjects will not be treated in a new cohort until all subjects in the previous cohort had completed the DLT evaluation period and ≤ 1 of 6 subjects had experienced a DLT. If ≥ 2 of 6 subjects experienced a DLT at Dose Level C, subjects will be treated at Dose B' as part of the dose-escalation phase of this study. Dose Level B': venetoclax 100mg daily administered on day -11, followed by 200mg daily administered on day -10 and 400mg daily administered on day -9 to -6 (total venetoclax dose: 1900mg) The maximum tolerated dose (MTD) is defined as the highest Dose Level at which ≤ 1 of 6 subjects had experienced a DLT. The dose-expansion phase involves recruitment of up to 12 patients at the MTD.
