Randomized comparative trial of pegylated liposomal doxorubicin versus bleomycin and vincristine in the treatment of AIDS-related Kaposi's sarcoma. International Pegylated Liposomal Doxorubicin Study Group.

PURPOSECytotoxic chemotherapy is frequently required for the more severe manifestations of human immunodeficiency virus (HIV)-related Kaposi's sarcoma. Combinations of bleomycin and vincristine (BV) or BV with the addition of doxorubicin (ABV) are the most commonly used regimens against which new treatments may be compared. We report a multicenter phase III study that compared pegylated liposomal doxorubicin (PLD) to the BV combination.PATIENTS AND METHODSWe conducted a randomized study that compared PLD 20 mg/m2 with a combination of bleomycin 15 IU/m2 and vincristine 2 mg in 241 patients with HIV-related Kaposi's sarcoma. Both regimens were administered by intravenous infusion every 3 weeks for six cycles.RESULTSA total of 121 patients received PLD and 120 patients the BV combination. The response to PLD was superior to BV: 58.7% versus 23.3% (P < .001). Patients who were randomized to receive BV, however, were more likely to terminate treatment early because of an adverse event (26.7% v 10.7%), and few...
