Document 3013 DOCN M94A3013 TI Liposomal doxorubicin in AIDS-related Kaposi's sarcoma. DT 9412 AU Caldeira L; Antunes F; Carvalho C; Duarte N; Doroana M; Forte M; Servico de Doencas Infecciosas, Hospital de Santa Maria,; Lisbon. SO Int Conf AIDS. 1994 Aug 7-12;10(1):173 (abstract no. PB0119). Unique Identifier : AIDSLINE ICA10/94369562 AB The authors report their experience with a new formulation of liposomal doxorubicin (DOX-SL) in the treatment of this disease. Seven HIV1+ male homosexual pts of caucasian origin (ages 29-42) were treated i.v. with 20mg/m2/cycle of this investigational formulation. At the beginning of therapy all pts had KS-associated edema and one had GI involvement. Cycles were administered every 2 weeks for the first 6 and every 3 weeks thereafter. Four of the pts had previously been treated with the combination of bleomycin and vincristine for a median of 6 cycles (range 3-9), one of these pts had two additional cycles of daunorubicin and 2 had been treated with the combination of alpha-IFN and low dose AZT. All of the pts had been switched to DOX-SL due to disease progression. RESULTS: A total of 77 cycles were administered between July 92 and December 93 with an median of 11 cycles per pt (range 2-25). Six of the 7 pts (85%) achieved a partial response, as assessed by the reduction or disappearance of lesion-associated edema, reduction in the number of lesions on examination and reduction of the surface covered by 5 target lesions measured at every visit. Partial response was obtained within a median of 3 cycles (range 1-4) and persisted in 5/6 pts who completed, at least, 6 cycles. Three pts died, 2 before completing 6 cycles and 1 of these, who died after 2 cycles, was the only pt who did not show a partial response (stable disease). None of the deaths were due to the study drug or to KS-related complications. Repeated rectoscopy in the pt with previously documented rectal disease showed no evidence of KS. Grade II neutropenia was reported in 7/7 pts (appearance ranging from cycle 1 to 14) and reached grade III in 2/7 pts. Other probably drug-related Adverse Events (AEs) (grade II or greater) were nausea (grade II in 5/7) and anemia (grade II in 2/7). One pt presented with RBB block with no change in cardiac function as assessed by echocardiography. In only, 2/77 cycles were reported local reactions due to drug administration. DISCUSSION: Treatment of AIDS-related KS with 20 mg/m2 of DOX-SL every two to three weeks was associated with an overall good response and safety in the long term even in patients previously unresponsive to other chemotherapeutic regimens.
