1 1 8 November 2005 ODAC: DOXIL ®, AIDS-related KS Studies of DOXIL for AIDS-related KS (Pre-HAART) Study No.Design No. of pts.Objective Response Rate/Results 30-10Phase 3 comparison to ABV 258DOXIL (46.2%) vs. ABV (25.6%) 30-11Phase 3 comparison to BV241DOXIL (58.7%) vs. BV (23.3%) 30-12Open-label, non-comparative extension 871DOXIL (65.9%) (n = 41 patients w/prior therapy) 30-14Randomized, crossover, PK and tumor localization 43DOXIL selectively accumulates into KS lesions No significant differences in PK parameters b/w doses 30-21Phase 1/2, cardiac biopsy data; comparison to cardiac damage 10Less myocardial damage observed in patients treated with DOXIL compared to their matched doxorubicin controls Note: A total of 10 DOXIL studies of varying design were completed for AIDS related KS
