Tandem Transplantation in Multiple Myeloma (MM) Patients With <12 Months of Prior Treatment

Study Overview
=================
Brief Summary
-----------------
The two objectives of this study are: To increase the 2-year event-free survival from 55%, established with Total Therapy II (UARK 98-026), to 75% in myeloma patients with cytogenetic abnormalities, and from 80%, established with the Total Therapy II regimen, to 95% in myeloma patients without cytogenetic abnormalities. To determine whether bortezomib, thalidomide, and dexamethasone can be safely incorporated with transplant 1 into the established pre-transplant regimen of high-dose melphalan (used in Total Therapy II) and whether Velcade and gemcitabine can be safely added to the transplant 2 high-dose chemotherapy regimen of combination melphalan and BCNU.

Detailed Description
-----------------
This study is targeted towards patients who have been diagnosed with Multiple Myeloma and have had no prior autologous or allogeneic transplant. Furthermore, only up to 12 months of prior treatment are allowed in this patient population. The study schema consists of one round of induction chemotherapy, two transplants, one round of consolidation chemotherapy, and two years of maintenance treatment. This study design differs from its historical predecessors in the following manner: In contrast to Total Therapy II and III, which only allow enrollment of patients with at most one cycle or one month of treatment prior to enrollment, the proposed study allows enrollment of patients with up to 12 months of prior treatment. No statistically significant difference in outcome between patients with one or no cycle of preceding therapy and those with up to 12 months of prior therapy. This should allow enrollment of significantly more myeloma patients. Induction therapy has been reduced to a single cycle. Bortezomib and thalidomide have been added to the transplant regimen. BCNU is added to the second transplant to high dose melphalan. Gemcitabine is added to the second transplant regimen. Consolidation treatment has been reduced to a single cycle. The first year of maintenance is with bortezomib, thalidomide and dexamethasone, and the second year of maintenance therapy consists of dexamethasone only. The novel agents thalidomide and bortezomib are not introduced upfront, but only with transplantation and maintenance.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Patients must have the diagnosis of active MM requiring treatment. Patients with a previous history of smoldering myeloma will be eligible if there is evidence of progressive disease requiring chemotherapy. Protein criteria must be present (quantifiable M-component of IgG, IgA, IgD, or IgE and/or urinary kappa or lambda light chain, Bence-Jones protein, or Free Kappa Light Chain or Free Lambda Light Chain) in order to evaluate response. Non-secretory patients are eligible provided the patient has > 20% plasmacytosis OR multiple (>3) focal plasmacytomas or focal lesions on MRI. Patients must have received no more than 12 months of prior chemotherapy for this disease. Patients may have received prior radiotherapy provided approval has been obtained by the Principal Investigator. Patients must be 18-75 years of age at the time of initial registration. Ejection fraction by ECHO or MUGA ≥ 40% performed within 60 days prior to registration. Patients must have adequate pulmonary function studies > 50% of predicted on mechanical aspects (FEV1, FVC) and diffusion capacity (DLCO) > 50% of predicted, within 60 days of registration. If the patient is unable to complete pulmonary function tests due to MM related pain or condition, exception may be granted if the principal investigator documents that the patient is a candidate for high dose therapy. Patients must have a creatinine < 3 mg/dl and a creatinine clearance >30mL/min Patients must have a performance status of 0-2 based on SWOG criteria. Patients with a poor performance status (3-4), based solely on bone pain will be eligible. All patients must be informed of the investigational nature of this study and must have signed an IRB-approved informed consent in accordance with institutional and federal guidelines. Exclusion Criteria: Platelet count < 30 x 109/L, unless myeloma-related. Greater than a grade 2 peripheral neuropathy. Hypersensitivity to bortezomib, boron, or mannitol. Uncontrolled diabetes. Recent (< 6 months) myocardial infarction, unstable angina, difficult to control congestive heart failure, uncontrolled hypertension, or difficult to control cardiac arrhythmias. Evidence of chronic obstructive or chronic restrictive pulmonary disease. Patients must not have light chain deposition disease-related renal failure or creatinine > 3 mg/dl. Patients must not have prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer for which the patient has not received treatment for one year prior to enrollment. Other cancers will only be acceptable if the patient's life expectancy exceeds five years. Patients must not have significant co-morbid medical conditions or uncontrolled life threatening infection. Pregnant or nursing women. Women of child-bearing potential must have a negative pregnancy test documented within one week of registration. Women and men of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Tandem autologous stem cell transplant<br>Induction: DPACE(dexamethasone,cisplatin,doxorubicin,cyclophosphamide,etoposide) chemotherapy plus stem cell collection. Additional stem cell collection and/or chemotherapy may be required. After collection, participants will receive dexamethasone x 4 days every 14 days. Transplant 1: The transplant preparative regimen will be bortezomib/thalidomide/dexamethasone/melphalan. Once recovered, participants start thalidomide daily and dexamethasone x 4 days every 21 days. Consolidation (if administered): VDT-PACE(bortezomib,dexamethasone,thalidomide,cisplatin,doxorubicin,cyclophosphamide, etoposide) Transplant 2: 8 weeks to 6 months after the first transplant, participants will have the second transplant Maintenance: Year 1- VTD (bortezomib, thalidomide, dexamethasone) cycles.
