Bortezomib, Thalidomide, and Dexamethasone After Melphalan and Stem Cell Transplant in Treating Patients With Stage I-III Multiple Myeloma
Multiple Myeloma and Plasma Cell Neoplasm, Neurotoxicity
About this trial
This is an interventional treatment trial for Multiple Myeloma and Plasma Cell Neoplasm focused on measuring neurotoxicity, stage I multiple myeloma, stage II multiple myeloma, stage III multiple myeloma
Eligibility Criteria
Inclusion Criteria:
- Multiple Myeloma patients with symptomatic disease, stage II or III at diagnosis or progressive stage I requiring chemotherapy and/or radiation therapy (by Salmon-Durie classification), who are not eligible for tandem transplant study using TMI; because of previous radiation or eligibility criteria; documentation of disease staging by both Salmon-Durie classification and International Staging System (ISS) is required
- Patients with non-secretory myeloma should have measurable serum free-light chain protein by the Free-lite test or measurable disease such as a soft tissue myeloma
- A minimum of 4 x 10^6 of CD 34 Positive cell/kg has been harvested
- A Karnofsky performance status (KPS) of >= 70% is required unless the KPS is impaired due to bone disease
- No contraindication to the collection of a minimum of 4 x 10^6 CD34+ cells/kg by apheresis
- All patients must have signed a voluntary, informed consent in accordance with institutional and federal guidelines
- Bilirubin =< 1.5 mg/dl
- Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvate transaminase (SGPT) < 2.5 x upper limits of normal
- Creatinine clearance of >= 40cc/min
- Absolute neutrophil count of > 1000/ul
- Platelet count of > 100,000/ul
- Cardiac ejection fraction >= 45% by multigated acquisition (MUGA) scan and/or by echocardiogram
- Diffusing capacity of the lung for carbon monoxide (DLCO) >= 50% of predicted lower limit
- Human immunodeficiency virus (HIV) antibody tests negative
- No other medical, or psychosocial problems which in the opinion of the primary physician or principal investigator would place the patient at unacceptably high risk from this treatment regimen
Exclusion Criteria:
- Presence of peripheral neuropathy >= grade II
- Patients with evidence of disease progression (with >= 25% increase in M protein) on bortezomib and or thalidomide therapy prior to transplant
- Pregnant or nursing women, as well as women of child bearing age, who are unwilling to use a dual method of contraception and men who are unwilling to use condom
- Patients with history of hypersensitivity to bortezomib, boron or mannitol

Arms of the Study
Arm 1
Experimental
Treatment (stem cell transplant, maintenance treatment)
Patients receive high-dose melphalan IV over 30 minutes on days -2 and -1 and undergo autologous peripheral blood stem cell transplantation on day 0. Patients receive filgrastim IV or SC beginning on day 5 and continuing until blood counts recover. Beginning 4 to 8 weeks after transplantation, patients receive maintenance therapy comprising bortezomib IV on days 1, 8, and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients also receive oral dexamethasone on days 1 to 4. Treatment with dexamethasone repeats every month for 12 months in the absence of disease progression or unacceptable toxicity. Beginning 2 weeks after completion of bortezomib, patients receive oral thalidomide once daily until disease progression.
