TLC D-99 is a unique liposomal formulation of doxorubicin that consists of phosphatidyl choline/cholesterol. The objectives of the study were to evaluate safety and efficacy of two doses of TLC D-99 in the treatment of patients with AIDS-related Kaposi's Sarcoma (KS). Forty HIV-infected persons with biopsy-proven KS were randomized to receive TLC D-99 at doses of either 10 (low) or 20 (high) mg/m2 every 2 weeks. Patients assigned to the low-dose arm could be escalated to the high-dose arm if their KS progressed after 3 cycles of therapy. Median age was 35 years (range, 26-47) and median CD4 count was 13 (range, 0-440). Nineteen patients were assigned to receive the low dose, and 21 patients were assigned to the high dose. Partial response occurred in 15% (6 of 40) of the patients or in 5% (1 of 19) and 24% (5 of 21) in the low- and high-dose arms, respectively; stable disease was observed in 65% (26 of 40) or in 68% (13 of 19) and 62% (13 of 21) in the low and high doses, respectively. Neutropenia was the major toxicity and was observed in 68 and 81% of patients with the low- and high-dose arms, respectively; grade 4 neutropenia was observed in 16 and 14%, respectively. Mild alopecia was noted in only 8%. Therefore, TLC D-99 is active against AIDS-related KS, and the response is dose-dependent.
