A Phase II Study of Idarubicin and Prednisone in Multiple Myeloma

Abstract

Twenty-one patients with multiple myeloma were treated with idarubicin 45 mg/m2 orally day 1 and prednisone 60 mg/m2 day 1-4 every three weeks. Moderate to severe gastrointestinal and hematopoietic toxicity were observed. Twelve of the twenty-one patients had relapsed on prior treatment. Of these, 2 patients responded. Two patients had primary resistant disease, neither responded. Seven patients had no prior treatment, three responded. ldarubicin and prednisone have modest activity in refractory myeloma, with short duration of response and severe toxicity.
