Brief Summary:
This phase II trial studies how well busulfan, fludarabine, donor stem cell transplant, and cyclophosphamide in treating patients 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 patient they may help the patient'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 patients with multiple myeloma or myelofibrosis.

Detailed Description:


I. To evaluate non-relapse mortality (NRM) up to day +100.


I. To evaluate non-relapse mortality (NRM) up to day +365. II. To evaluate the incidence of acute graft versus host disease (GVHD) and chronic GVHD up to day +365 post-transplant.

III. To evaluate the overall survival and disease free survival up to 1 year. IV. To evaluate clinical response and molecular response (complete response and partial response) up to 1 year.


Patients receive busulfan intravenously (IV) over 2 hours and fludarabine IV over 30 minutes on days -5 to -2. Patients undergo hematopoietic cell transplantation (HSCT) on day 0. Patients then receive cyclophosphamide IV over 60 minutes on days 3 and 4.

After completion of study treatment, patients are followed up for 1 year.

Primary Outcome Measures :
  1. Non-relapse mortality (NRM) [ Time Frame: Up to day 100 ]
    NRM is defined as death due to graft versus host disease, infections, sepsis, organ (lung, liver, kidney) toxicity. The outcome will be reported along with an exact binomial confidence intervals for informal comparison to the literature.

Secondary Outcome Measures :
  1. Cumulative incidence of clinical complete response and molecular complete response (complete response and partial response) [ Time Frame: Up to 1 year ]
  2. Disease free survival [ Time Frame: Up to 1 year ]
    Kaplan-Meier techniques will be used.

  3. Incidence of acute graft versus host disease (GVHD) [ Time Frame: Up to day 365 ]
    Will be done descriptively.

  4. Incidence of chronic GVHD [ Time Frame: Up to day 365 ]
    Will be assessed based on criteria established by the National Institutes of Health Consensus Development Project in 2005, and recently updated in 2014. Will be done descriptively.

  5. Non-relapse mortality [ Time Frame: Up to day 365 ]
    Will be done descriptively.

  6. Overall survival [ Time Frame: Up to 1 year ]
    Kaplan-Meier techniques will be used.

  7. Relapse rate [ Time Frame: Up to day 365 ]
    Will be done descriptively.
