Summary:

      The goal of this clinical research study is to learn if the combination of gemcitabine,
      busulfan, and melphalan, when given before a stem cell transplant, can help to control
      refractory myeloma. The safety of this study treatment will also be studied.
    

Eligibility criteria:

        Inclusion Criteria:

          1. Age 18 to 70 years.

          2. Patients with myeloma treated with first-line therapy including lenalidomide,
             bortezomib or thalidomide, and one or more of the following: 2.1) M paraprotein
             greater than 1 g/dL at HDC. 2.2) Less than partial response to first-line therapy.
             2.3) Relapse after first-line therapy. 2.4) Relapse after a prior autologous stem-cell
             transplant.

          3. Adequate renal function, as defined by serum creatinine </=1.8 mg/dL and/or estimated
             serum creatinine clearance >/=50 ml/min

          4. Adequate hepatic function, as defined by serum glutamate oxaloacetate transaminase
             (SGOT) and/or serum glutamate pyruvate transaminase (SGPT) </=3 x upper limit of
             normal; serum bilirubin and alkaline phosphatase </=2 x upper limit of normal, unless
             proven to be due to disease involvement.

          5. Adequate pulmonary function with forced expiratory volume at one second (FEV1), forced
             vital capacity (FVC) and diffusing capacity of lung for carbon monoxide (DLCO) >/=50%
             of expected corrected for hemoglobin and/or volume.

          6. Adequate cardiac function with left ventricular ejection fraction >/=40%. No
             uncontrolled arrhythmias or symptomatic cardiac disease.

          7. Zubrod performance status <2.

          8. Negative Beta human chorionic gonadotropin (HCG) text in a woman with child-bearing
             potential, defined as not post-menopausal for 12 months or no previous surgical
             sterilization

        Exclusion Criteria:

          1. Patients with grade >/= 3 non-hematologic toxicity from previous therapy that has not
             resolved to </= grade 1.

          2. Patients with prior whole brain irradiation

          3. Patients with active hepatitis B, either active carrier (HBsAg +) or viremic (HBV DNA
