Trial Description

Summary

RATIONALE: Biological therapies, such as thalidomide and clarithromycin, may stimulate the immune system in different ways and stop cancer cells from growing. Thalidomide and clarithromycin may also stop the growth of multiple myeloma by blocking blood flow to the cancer. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving thalidomide together with dexamethasone and clarithromycin after an autologous or syngeneic bone marrow or stem cell transplant may be an effective treatment for multiple myeloma.

PURPOSE: This phase II trial is studying how well giving thalidomide together with dexamethasone and clarithromycin works in treating patients who have undergone a previous autologous or syngeneic bone marrow or stem cell transplant for multiple myeloma.

Further Study Information

OBJECTIVES:

• Determine the toxicity of maintenance therapy comprising thalidomide, dexamethasone, and clarithromycin in patients with multiple myeloma who have undergone prior autologous or syngeneic bone marrow or peripheral blood stem cell transplantation.

• Determine the median time to disease progression in patients treated with this regimen.

• Determine overall survival and disease-free survival of patients treated with this regimen.

OUTLINE: Patients receive oral thalidomide once daily, oral dexamethasone once weekly, and oral clarithromycin twice daily for up to 1 year in the absence of disease progression or unacceptable toxicity. After completion of 1 year of treatment, patients discontinue oral clarithromycin, receive tapering doses of oral dexamethasone once weekly for 8 weeks, and continue to receive oral thalidomide once daily in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 2-3 years.
