Purpose:

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of R115777 in treating patients who have relapsed or refractory multiple myeloma.


Study summary:

OBJECTIVES: I. Determine the rate of objective response and disease stabilization in patients with relapsed or refractory multiple myeloma treated with R115777. II. Determine whether the degree of inhibition of FTase activity and farnesylation of lamin-B, H-, K-, and N-RAS in peripheral blood mononuclear cells and tumor tissue correlates with tumor response in patients treated with this regimen. III. Determine whether the presence of activating RAS mutations in myeloma cells predicts treatment response in patients treated with this regimen. IV. Correlate R115777 plasma levels and RAS mutation status with tumor response in patients treated with this regimen. OUTLINE: Patients receive oral R115777 twice daily on days 1-21. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed for at least 30 days. PROJECTED ACCRUAL: Approximately 12-42 patients will be accrued for this study within 25 months.
