Brief summary

The primary objective is to assess the safety of the addition of venetoclax to reduced intensity conditioning for HLA-matched and haploidentical combined HSC and kidney transplantation as measured by stable full donor hematopoiesis and absence of CTCAE grade IV or V toxicity attributable to venetoclax.

Interventions

DRUGVenetoclax

Venetoclax 400mg orally once daily on days -8 through -1 with daily monitoring for tumor lysis syndrome. Venetoclax tablets will be swallowed (not crushed). Venetoclax dosing will not be repeated in the event of vomiting.

Cytoxan Day -6 \& -5 Fludarabine Day -4, -3, -2 TBI Day -1

PROCEDUREKidney Transplant

Living donor kidney transplant

PROCEDUREHematopoietic Cell Transplantation

Donor bone marrow (target of 4 x 108 nucleated cells/kg of recipient ideal body weight) PBSC A goal dose of 5 x 106 CD34+ cells / kg of recipient actual body weight will be infused (minimum acceptable is 2 x 106 CD34+ cells / kg).

Inclusion criteria

Recipient Inclusion Criteria: * Patient ages 18-70 * Underlying hematological malignancy which is deemed as being potentially curable with allogeneic bone marrow or PBSC transplantation by the BMT voting team. * Hematological malignancies include, but are not limited to: acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CML), chronic lymphocytic leukemia (CLL), non-Hodgkin lymphoma (NHL), Hodgkin lymphoma, multiple myeloma (MM), myelodysplastic syndrome (MDS. Patient should be in a partial (PR) or complete remission (CR) at the time of the transplant. * Existence of an HLA-matched or haploidentical relative who passes standard donor evaluations for bone marrow and kidney donation * LVEF \> 40% as measured by echocardiography or MUGA * FEV1, FVC, and DLCO \> 50% of predicted as measured by standard PFTs * Total bilirubin \< 2.0 (unless diagnosis of Gilbert's or hemolysis is made) and AST, ALT, alkaline phosphatase all \< 5x institutions upper limit of normal * ABO compatibility in the host vs. graft direction * Men and women of reproductive potential must agree to use a reliable method of birth control during the treatment, and women should do so for a period of 1 year following the transplant. * Participants should be on dialysis or have a CrCl ≤ 35 ml/min * Life expectancy greater than 6 months * Recipient ability to understand and provide informed consent Donor Inclusion Criteria: * HLA matched or haploidentical relative as defined by 3/6, 4/6, or 5/6 HLA-matched at HLA -A, -B, or -DRB1 who is 18-70 years of age * ECOG performance status 0 or 1 * Excellent health per conventional pre-donor history (medical and psychosocial evaluation) • Acceptable laboratory parameters (hematology in normal or near-normal range; liver function \< 3 times the upper limit of normal and normal creatinine) * Compatible ABO blood group * Negative donor lymphocyte cross match * No positive testing for active viral infection (Hepatitis B, Hepatitis C, HIV) * Donor ability to understand and provide informed consent * Meets standard institutional criteria for both bone marrow or peripheral blood stem cell (PBSC) and kidney donation

Exclusion criteria

* Active serious infection * Participation in other investigational drug use at the time of enrollment * Positivity for active infection with HIV, HCV, or HBV * ABO blood group incompatibility in the host-vs-graft direction
