Brief summary

In this phase I trial, patients with relapsed or refractory multiple myeloma will receive standard autologous stem cell transplant conditioned with high dose melphalan. In addition to Melphalan, the conditioning will include targeted total marrow irradiation (TMI). This is a conventional 3+3 phase I trial with increasing doses of TMI from minimum 3Gy to Maximum 9Gy.

Detailed description

In this phase I trial, patients with relapsed or refractory multiple myeloma will receive standard high dose melphalan with autologous stem cell rescue. In addition the pre-transplant conditioning will include targeted total marrow irradiation (TMI). This conventional 3+3 phase I trial will increase the dose of TMI until the maximum tolerated dose (MTD) is reached. Initial patients enrolled will receive the lowest possible dose of 3Gy. Maximum dose will be 9Gy.

Interventions

Subjects will receive standard melphalan 200mg/m\^2 (100mg/m\^2 day-2 and day-1) conditioning with autologous stem cell rescue

Subjects in this trial will receive total marrow irradiation 3Gy per day for up to four days and as little as one day

DRUGMelphalan

Subjects will receive standard melphalan 200mg/m\^2 (100mg/m\^2 day-2 and day-1) conditioning therapy prior to transplant

Subjects to begin GCSF 5 μg/kg/d SC or IV on Day 5 and continue until ANC \> 1000/mm\^3 over period of 3 days.

Inclusion criteria

1. Patients meeting criteria for symptomatic myeloma 2. Patients who have progressive myeloma following initial induction (patients may have received any number of treatment regimens including prior autologous transplant) 3. Patient age 18-75 years at time of enrollment 4. Karnofsky performance status of ≥70 5. Cardiac function: LVEF \>40% 6. Hepatic: Bilirubin \<2x upper limit of normal and ALT and AST \< 2.5x the upper limit of normal 7. Renal: Creatinine clearance of \>30mL/min, estimated or calculated 8. Pulmonary: DLCO, FEV1, FVC \>50% of predicted (after correction for hemoglobin)

Exclusion criteria

1. Patients with diagnosis of plasma cell leukemia 2. Patients with truly non secretory myeloma (patients with light chain disease are eligible) 3. Pregnant or breast-feeding 4. Uncontrolled viral, fungal or bacterial infection Note: Infection is permitted if there is evidence of response to medication. Eligibility of HIV infected patients will be determined on a case-by-case basis. 5. Patients who have undergone prior allogeneic stem cell transplant 6. Prior solid organ transplant 7. Patients receiving prior radiation to more than 20% of bone marrow containing areas

Response Criteria Stringent Complete Response (sCR) in addition to CR all of the following: 1. Normal free light chain ratio (FLC) 2. Absence of clonal cells in the bone marrow by immunohistochemistry if this is performed Complete Response (CR) requires all of the following: 1. Absence of the original monoclonal paraprotein in the serum or the urine by routine electrophoresis and by immunofixation. The presence of new monoclonal bands consistent with oligoclonal immune reconstitution does not exclude CR. 2. Less than 5% plasma cells in a bone marrow aspirate and bone marrow biopsy if this is performed. 3. No increase in size or number of lytic bone lesions on radiologic investigation (development of compression fracture does not exclude CR and radiographs are not required to document CR if not clinically indicated) 4. Disappearance of soft tissue plasmacytoma
