Oral idarubicin in adult acute leukemia: a preliminary experience.
|
| Abstract |
Twelve patients affected by different types of acute leukemia received idarubicin (4-demethoxy-daunorubicin) by oral route at the total dosage of 45, 60 or 90 mg/m2 distributed over three consecutive days. Drug response was assessed by the decrease in blast cells in peripheral blood and showed some variations between the different types of leukemia. Acute myelogenous leukemia patients and those with blastic crisis of chronic myeloid leukemia appeared to be the more responsive groups; however, the lower dose schedule could explain the less satisfactory results obtained in lymphatic leukemia patients. Data suggest that idarubicin is absorbed rapidly after oral ingestion, in spite of nausea and vomiting, which appeared 3-4 h later and were easily controlled by antiemetic therapy. The purpose of fractionating the drug dosage over three consecutive days is to prolong in the blood an elevated concentration of the main idarubicin metabolite (13-dihydro-derivative), which presents in experimental models an antileukemic potency similar to the parent compound. This study confirms that idarubicin is effective in acute leukemia also by oral route. This formulation could offer some advantages for subjects who cannot tolerate parenteral chemotherapy and it could be proposed in maintenance leukemia protocols.
