Acute Myeloid Leukemia, Chronic Myelomonocytic Leukemia, Myelodysplastic Syndrome
Conditions
Brief summary
This phase II trial studies the effect of venetoclax together with busulfan, cladribine, and fludarabine in treating patients with high-risk acute myeloid leukemia or myelodysplastic syndrome who are undergoing stem cell transplant. Chemotherapy drugs, such as venetoclax, busulfan, cladribine, and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding venetoclax to the current standard of care stem cell transplant regimen of busulfan, fludarabine, and cladribine may help to control high-risk acute myeloid leukemia or myelodysplastic syndrome.

Overall survival 7. Graft versus host disease-relapse free survival (GRFS) Phase 3 Portion Primary Objective 1\) To compare progression free survival between two arms Arm 1 Standard of Care: fludarabine + IV busulfan (FluBu) versus Arm 2 Experimental: Venetoclax + Fractionated busulfan, cladribine, and fludarabine Secondary Objectives To compare following between two arms 1.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 1-year progression free survival (PFS) | At 1 year post-transplant | The proportion of patients who are alive without disease relapse (PFS) at one year will be reported along with the corresponding 95% credible interval. Cox proportional hazards regression will be used to assess the association between PFS and clinical and treatment covariates of interest. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall survival (OS) | Up to 3 years post-transplant | OS will be calculated from the time of transplant by the method of Kaplan and Meier. |
| Graft-versus (vs.)-host disease-free, relapse-free survival (GRFS) | Up to 3 years post-transplant | GRFS will be calculated from the time of transplant by the method of Kaplan and Meier. |
| Time to platelet engraftment | From the time of transplant up to 3 years | The time to platelet engraftment will be calculated from the time of transplant and estimated by the Kaplan-Meier method. |
| Time to neutrophil engraftment | From the time of transplant up to 3 years | The time to neutrophil engraftment will be calculated from the time of transplant and estimated by the Kaplan-Meier method. |
| Incidence of acute and chronic graft-vs.-host disease (GvHD) | Up to 3 years post-transplant | The cumulative incidence of acute and chronic GvHD with the competing risks of relapse and death will be estimated using the method of Gooley, and the method of Fine and Gray will be used to model the association between both parameters and clinical and treatment characteristics of interest. |
| Incidence of relapse and non-relapse mortality | Up to 3 years post-transplant | The cumulative incidence of non-relapse mortality and relapse will also be assessed in a competing risks framework, with similar analyses performed. |
| Incidence of adverse events | Up to 3 years post-transplant | Descriptive statistics will be used to summarize adverse events. The number and proportion of subjects with treatment emergent adverse events will be reported. All other safety parameters will be summarized using descriptive statistics or frequency counts. Graphical summaries will be used where appropriate. |
