SU5416 in Treating Patients With Refractory or Relapsed Multiple Myeloma

OBJECTIVES: I. Determine the response rate and response duration of patients with refractory or relapsed multiple myeloma treated with SU5416. II. Determine the toxicity of SU5416 in this patient population.

OUTLINE: This is a multicenter study. Patients receive SU5416 IV over 1 hour twice weekly. Treatment continues in the absence of unacceptable toxicity or disease progression. Patients are followed for survival.

PROJECTED ACCRUAL: A total of 20-38 patients will be accrued for this study within 2 years.
