Allogeneic Stem Cell Transplantation for Multiple Myeloma and Myelofibrosis

Busulfan, Fludarabine, Donor Stem Cell Transplant, and Cyclophosphamide in Treating Participants With Multiple Myeloma or Myelofibrosis

This phase II trial studies how well busulfan, fludarabine, donor stem cell transplant, and cyclophosphamide in treating participants with multiple myeloma or myelofibrosis. Drugs used in chemotherapy, such as busulfan, fludarabine, and cyclophosphamide, 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. Giving chemotherapy before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the participant they may help the participant's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving busulfan and fludarabine before and cyclophosphamide after donor stem cell may work better in treating participants with multiple myeloma or myelofibrosis.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Non-relapse Mortality (NRM) at Day 100	NRM is defined as death due to GVHD, infections, sepsis, organ (lung, liver, kidney) toxicity. Death from underlying disease (i.e. progression or relapse) is not considered NRM.	Up to day 100

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Non-relapse Mortality (NRM) at Day 365	NRM is defined as death due to GVHD, infections, sepsis, organ (lung, liver, kidney) toxicity. Death from underlying disease (i.e. progression or relapse) is not considered NRM.	Up to day 365
Incidence of Acute Graft Versus Host Disease (GVHD)	Cases of acute graft versus host disease (GVHD) will be diagnosed by the treating physician and will be reported as a count of participants with acute GVHD.	Up to day 365
Incidence of Chronic GVHD	Chronic GVHD will be assessed based on criteria established by the National Institutes of Health Consensus Development Project in 2005, and recently updated in 2014. This will be reported as a count of participants diagnosed with chronic GVHD	Up to day 365
Overall Survival at One Year	Overall survival is defined as the number of participants remaining alive up to one year following stem cell transplant.	Up to 1 year
Disease Free Survival at One Year	Disease free survival is defined as an absence of disease relapse or progression up to one year following stem cell transplant.	Up to 1 year
Number of Participants With Different Clinical Responses	Clinical Responses were determined by disease-specific criteria taking into account multiple clinical and molecular markers. Multiple Myeloma (MM) response was determined using International Myeloma Working Group (IMWG) consensus criteria for response. Participants with MM had either Stringent Complete Response (sCR) or Very Good Partial Response (VGPR). Myelofibrosis (MF) response was determined using International Working Group-Myeloproliferative Neoplasms Research and Treatment (IWG-MRT) and European LeukemiaNet (ELN) consensus criteria. Participants with MF had either Complete Response (CR) or Stable Disease (SD) (also referred to in the protocol as no response).	Up to 1 year
Number of Participants With Minimal Residual Disease (MRD) Response	After bone marrow transplant, bone marrow was collected every 3-6 months (as clinically indicated per treating investigator) for up to one year after bone marrow transplant. Bone marrow was evaluated by a clinical pathologist for any evidence of multiple myeloma (MM) or myelofibrosis (MF). Evidence of MM or MF in the bone marrow is referred to as minimal residual disease (MRD). A participant with evidence of MRD is MRD-positive. A participant with no evidence of MRD is MRD-negative, which is considered an MRD response. This outcome reports the number participants with MRD responses any time between bone marrow transplant up to one year of follow-up.	Up to 1 year
