Clinical Trial: Sorafenib in Treating Patients With Relapsed or Refractory Multiple Myeloma

This study is not yet open for patient recruitment.
Verified by National Cancer Institute (NCI) November 2005

Sponsors and Collaborators: Southwest Oncology Group
National Cancer Institute (NCI)
Information provided by: National Cancer Institute (NCI)
ClinicalTrials.gov Identifier: NCT00253578

Purpose

RATIONALE: Sorafenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.

PURPOSE: This phase II trial is studying how well sorafenib works in treating patients with relapsed or refractory multiple myeloma.

Official Title: Phase II Study of Sorafenib in Patients With Relapsed or Refractory Multiple Myeloma

Further study details as provided by National Cancer Institute (NCI):

OBJECTIVES:

  • Determine the overall response rate (confirmed complete response, response, and partial response) in patients with relapsed or refractory multiple myeloma treated with sorafenib.
  • Determine the qualitative and quantitative toxic effects of this drug in these patients.
  • Determine the overall and progression-free survival of patients treated with this drug.
  • Correlate gene expression signatures with response in patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive oral sorafenib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically for 3 years.

PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study.
