PURPOSETo determine the efficacy and safety of pegylated-liposomal doxorubicin in patients with AIDS and Kaposi's sarcoma (AIDS-KS) who experienced failure of standard chemotherapy.METHODSFifty-three patients with advanced AIDS-KS who experienced disease progression or intolerable toxicities while receiving standard doxorubicin/bleomycin/vincristine (ABV) or bleomycin/vincristine (BV) chemotherapy were identified from a cohort of patients who were then treated with pegylated-liposomal doxorubicin. Patients received 20 mg/m2 pegylated-liposomal doxorubicin (Doxil; Sequus Pharmaceuticals, Inc, Menlo Park, CA) every 3 weeks.RESULTSNineteen patients (36%) had a partial response (PR) and one patient had a clinical complete response (CCR). The median duration of response and time (from study entry) to treatment failure were 128 and 134 days, respectively. Of 28 patients who experienced disease progression while receiving combination regimens that contained standard doxorubicin, the PR rate was 32%, which sugges...
