Unique Identifier : AIDSLINE ICA10/94369566 AB OBJECTIVE: The utility of current chemotherapeutic regimens in the treatment of AIDS-related Kaposi's sarcoma (AIDS-KS) is often compromised by both limited efficacy and substantial toxicity. Dox-SL, a long-circulating, liposomally encapsulated doxorubicin, has been demonstrated to specifically deliver high concentrations of doxorubicin to KS lesions. This phase II study was therefore performed to evaluate the efficacy and safety of Dox-SL in the treatment of moderate to severe AIDS-KS. METHODS: Patients were treated biweekly with Dox-SL, in almost all cases at 10 or 20mg/m2. Lesion response was assessed according to ACTG criteria prior to each cycle. RESULTS: Best response was determined for 196 patients and was achieved after a mean of 2.5 cycles (range: 1-20). Thirteen patients (6.6%) had a complete response (CR) to Dox-SL, 143 (73.0%) had a partial response (PR), 38 (19.4%) had stable disease while 2 (1.0%) had disease progression. The degree of response to Dox-SL did not appear to correlate with dose. Mean response duration (measured from the time of best response) was 95.6 days (range: 4-451) for PRs and/or CRs and 53.9 (range: 25-77) for CRs. Dox-SL was well-tolerated: only 6 patients discontinued therapy because of adverse events during the first 6 cycles. CONCLUSIONS: 1) Dox-SL has substantial activity in AIDS-KS; 2) Dox-SL is well-tolerated, and may lack much of the toxicity of free doxorubicin; 3) Further study of Dox-SL in AIDS-KS is justified.
