About this trial
This is an interventional treatment trial for Leukemia, Myeloid, Acute focused on measuring Venetoclax, Reduced intensity conditioning, Non-myeloablative conditioning, Allogeneic stem cell transplant, Acute leukemia, Myelodysplastic syndrome, Non-Hodgkin Lymphoma, Plasma Cell Myeloma, Graft-versus-host Disease, Engraftment, Graft-versus-Leukemia
Eligibility Criteria
Inclusion Criteria:
Patients are eligible for inclusion if all of the following criteria are met:
- Age ≥ 18 years
- Planned to undergo alloSCT for one of the following haematological malignancies: acute leukaemia (including myeloid and/or lymphoid lineage or biphenotypic), myelodysplastic syndrome, chronic lymphocytic leukaemia (CLL), B-cell non-Hodgkin lymphoma (NHL) and plasma cell myeloma
- Physician preference for a non-myeloablative conditioning regimen
- Available 10/10 HLA-matched related or unrelated haematopoietic stem cell donor
- Transplantation to be performed from a peripheral blood stem cell source
Adequate renal and hepatic function at screening as follows:
- Calculated creatinine clearance >50ml/min as measured by Cockroft Gault formula
- AST and ALT ≤ 3.0 x ULN
- Bilirubin ≤ 1.5 x ULN (except patients with Gilbert's Syndrome)
- Able to tolerate oral medications
Disease status at the time of transplantation as follows:
- Acute leukaemia in complete morphologic remission
- Myelodysplastic syndrome with less than 10% bone marrow blasts
- CLL in complete remission (CR), partial response (PR) or PR with lymphocytosis
- NHL in CR or PR
- Myeloma in CR, very good partial response (VGPR) or PR within 3 months of prior autologous stem cell transplantation as part of a tandem auto-allo transplant approach
- ECOG performance status 0-1
Exclusion Criteria:
Patients will be excluded from this study if any of the following criteria are met:
Moderate or high risk of tumour lysis syndrome prior to conditioning for allogeneic transplantation, defined as:
- For CLL: Diameter of any lymph node or tumour mass >5cm OR absolute lymphocyte count≥25x10^9/L
- For NHL: Diameter of any lymph node or tumour mass >5cm
Prior intolerance of venetoclax or another BCL-2 inhibitor with the exception of cytopenias. Patients with prior clinical tumour lysis syndrome following venetoclax or other BCL-2 inhibitor will be excluded from the study if at the time of prior TLS their disease burden was as follows:
- For CLL: Diameter of any lymph node or tumour mass <5cm OR absolute lymphocyte count≤25x10^9/L
- For NHL: Diameter of any lymph node or tumour mass <5cm
- Reticulin fibrosis of the marrow of grade MF 2-3
- Prior allogeneic stem cell transplantation
- Haemopoietic cell transplantation - comorbidity index (HCT-CI) score > 5
- Any currently active malignancy other than the primary indication for alloSCT (except localized basal cell carcinoma or squamous cell carcinoma of the skin)
- Uncontrolled systemic infection
- Known malabsorption syndrome
- Has received within 7 days prior to the first dose of venetoclax CYP3A4 inducers such as rifampicin, carbamazepine, phenytoin and St John's wort
- Has received within 7 days prior to the first dose of venetoclax CYP3A4 inhibitors
- Known positivity to HIV
- Significant physical or psychiatric comorbid illness that in the investigator's opinion would impair the patient's ability to participate in the study.
