Clinical Trial Summary

RATIONALE: Zoledronate may prevent bone loss and stop the growth of cancer cells in bone. Thalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. It is not yet know whether giving zoledronate together with thalidomide is more effective than zoledronate alone in treating multiple myeloma.

PURPOSE: This randomized phase III trial is studying zoledronate and thalidomide see how well they work compared with zoledronate alone in treating patients with early stage multiple myeloma.

Description:

OBJECTIVES:

Primary

• Compare time to progression in patients with early stage multiple myeloma treated with zoledronate with or without thalidomide.

Secondary

• Compare the response rate, 1-year progression-free survival rate, duration of response, and time to next therapy in patients treated with these regimens.

• Assess differences in toxicity of these regimens in these patients.

OUTLINE: This is a multicenter, randomized study. Patients are stratified according to the presence of lytic lesions on metastatic bone survey (yes vs no), beta-2 microglobulin level (high vs normal), and bone marrow labeling index (high [> 1.0%] vs low [≤ 1.0%]). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral thalidomide on days 1-28. Treatment with thalidomide repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients also receive zoledronate IV over 15 minutes on day 1. Treatment with zoledronate repeats every 84 days for 1 year and once a year thereafter in the absence of disease progression or unacceptable toxicity.

• Arm II: Patients receive zoledronate IV over 15 minutes on day 1. Treatment repeats every 84 days for 1 year and once a year thereafter in the absence of disease progression or unacceptable toxicity.

Blood samples are collected for research studies at baseline and after courses 3, 6, 9, and

12. Bone marrow aspirates are performed at baseline and after courses 6 and 12. Samples are evaluated for bone marrow angiogenesis; vascular endothelial growth factor (VEGF), VEGF receptor 1 (VEGFR-1), and VEGFR-2 expression; bone marrow angiogenesis-VEGF relationship; bone marrow angiogenesis/apoptosis rate relationship; bone marrow angiogenesis/plasma cell (PC) proliferation rate relationship; VEGF expression/apoptosis rate relationship; and VEGFR expression/PC proliferation rate relationship.

After completion of study treatment, patients are followed every 6 months for up to 5 years.

PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Disease Progression (TTP)	Time to disease progression (TTP) was defined as the time from randomization to the earliest documentation of disease progression. Participants were followed for a maximum of 5 years from registration. The median OS with 95% CI was estimated using the Kaplan Meier method, a two-sided (stratified) log-rank test was calculated.	randomization to progression (up to 5 years)	No
Secondary	12-month Progression-free Survival (PFS)	PFS at 12 months is a dichotomized outcome indicating whether or not a participant was progression free (and alive) at 12 months from the date of randomization.	12 months	No
Secondary	Number of Participants With a Confirmed Response (Complete Response [CR], Very Good Partial Response [VGPR] or Partial Response [PR]) on Two Consecutive Evaluations at Least 2 Weeks Apart in the First 12 Months of Treatment	Response is defined as follows: CR: Complete disappearance of M-protein from serum & urine on immunofixation, <5% plasma cells in bone marrow (BM); VGPR: >=90% reduction in serum M-component; Urine M-Component <100 mg per 24 hours; <=5% plasma cells in BM; PR: >= 50% reduction in serum M-Component and/or Urine M-Component >= 90% reduction or <200 mg per 24 hours; or >= 50% decrease in difference between involved and uninvolved FLC levels	12 months	No
