Disclosed are liposomal antitumor compositions having improved pharmacological characteristics. Liposomes described herein are formed through the incorporation of a particular class of anthracyclines, the 4-demethoxy-3'-desamino-2'-iodo analogs, shown to have extremely high incorporatio efficiencies of greater than 95%. These liposomes demonstrate an improved antitumor efficacy, with much reduced toxicity, against accepted tumor models, and further exhibit excellent stability upon storage, for example, in the form of a dried powder. |
