Bortezomib, Liposomal Doxorubicin Hydrochloride, Dexamethasone, and Cyclophosphamide in Treating Patients With Multiple Myeloma That Relapsed After Autologous Stem Cell Transplant

Location:

Trial status:

Inactive

Why is this study being done?

PRIMARY OBJECTIVES:

I. To evaluate the 1-year survival of patients with relapsed multiple myeloma treated with bortezomib, pegylated liposomal doxorubicin hydrochloride, dexamethasone, and cyclophosphamide.

SECONDARY OBJECTIVES:

I. To evaluate response rates in patients treated with this regimen. II. To evaluate the median time to progression in patients treated with this regimen.

III. To evaluate the toxicity of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive bortezomib IV on days 1, 4, 8, and 11; pegylated liposomal doxorubicin hydrochloride IV over 1 hour on day 4; oral dexamethasone on days 1, 2, 4, 5, 8, 9, 11, and 12; and cyclophosphamide IV over 2 hours on day 1. Treatment repeats every 21 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Peripheral blood and bone marrow samples may be collected for future research. Patients complete the FACT neurotoxicity questionnaire periodically.

After completion of study treatment, patients are followed up every 3 months for 3 years.

Who is eligible to participate?

Inclusion Criteria:

- Diagnosis of multiple myeloma that was symptomatic at the time of initial diagnosis

- Must have met the following criteria at one point during the disease course:

- Bone marrow plasmacytosis with ≥ 10% plasma cells or sheets of plasma cells or biopsy-proven plasmacytoma

- Anemia

- Hypercalcemia

- Bone disease (lytic bone lesions or pathologic fracture)

- Renal dysfunction

- Disease relapsed < 12 months after autologous stem cell transplantation (SCT)

- Fertile patients must use effective contraception

- No active, uncontrolled seizure disorder

- No seizures within the past 6 months

- No concurrent uncontrolled illness that would limit study compliance, including the following:

- Uncontrolled hypertension

- Symptomatic congestive heart failure

- Unstable angina

- Uncontrolled cardiac arrhythmia

- Uncontrolled psychiatric illness or social situation

- Active uncontrolled infection

- No peripheral neuropathy ≥ grade 2 according to the CTEP active version of the NCI CTCAE

- Prior malignancy allowed provided it was treated curatively and has not relapsed in 5 years

- Patients with basal cell skin cancer, in situ cervical cancer, or prostate cancer not requiring therapy are eligible

- No known allergy to bortezomib or anthracyclines
