Trial Information

A Phase II Trial of Dexamethasone and 13-cis-Retinoic Acid as First-Line Treatment for Multiple Myeloma

OBJECTIVES: I. Determine the response rate and duration of response of patients with
multiple myeloma treated with dexamethasone and isotretinoin. II. Determine the toxicity of
this regimen in these patients. III. Correlate the changes in serum interleukin (IL)-6,
IL-6R, and C-reactive and IL-6R expression on plasma cells in the bone marrow with response
in patients treated with this regimen.

OUTLINE: Patients receive oral dexamethasone on days 1-4, 9-12, and 17-20 and oral
isotretinoin daily. Treatment repeats every 5 weeks for at least 2 courses in the absence of
disease progression, insufficient response, or unacceptable toxicity. Patients achieving
adequate response continue treatment for 2 courses after achieving a plateau of monoclonal
protein, for a minimum of 6 courses total.

PROJECTED ACCRUAL: A total of 18-36 patients will be accrued for this study within 3 years.
