Bortezomib, Dexamethasone, and Cyclophosphamide in Treating Older Patients With Multiple Myeloma

• Status: Withdrawn
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies the side effects and how well lower doses of bortezomib, dexamethasone, and cyclophosphamide work in treating older patients with multiple myeloma. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving cyclophosphamide daily may kill more cancer cells. Giving bortezomib, cyclophosphamide, and dexamethasone may be an effective treatment for multiple myeloma.

Criteria

Inclusion Criteria:

• Patients must have a confirmed diagnosis of symptomatic myeloma in accordance with International Myeloma Working group (IMWG) criteria

• Bone marrow plasmacytosis with > 10% plasma cells or sheets of plasma cells or biopsy proven plasmacytoma

• Symptomatic disease, i.e., end-organ damage due to multiple myeloma (MM) including at least one of the following: anemia, hypercalcemia, bone disease (lytic bone lesions or pathologic fracture), or renal dysfunction

• Absolute neutrophil count (ANC) >= 1000 cells/mm^3 (without use of growth factors)

• Platelets >= 50,000 cells/mm^3

• Direct bilirubin =< 1.5 X upper limit of normal (ULN); elevated bilirubin is permissible if patient has a known history of elevated bilirubin due to Gilbert's or if elevated bilirubin is due to hemolysis

• Alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 1.5 X ULN

• Subjects must have the ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

• Prior treatment with > 1 cycle of any plasma cell myeloma (PCM) induction regimen (maximum 6 weeks of prior treatment)

• Prior radiation therapy is allowed

• Prior treatment for other cancers is allowed as long as patient meets criteria for adequate hematopoietic and organ function and is not actively on chemotherapy for another cancer

• Grade >= 2 peripheral neuropathy

• Second malignancy currently undergoing chemotherapy or radiotherapy; hormonal therapy for breast or prostate cancer is allowed

• Patients may not be receiving any other investigational agents

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to bortezomib, cyclophosphamide, dexamethasone or other agents used in this study

• Patients with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
