Abstract: The present invention discloses compositions comprising podophyllotoxins, analogs thereof, or derivatives thereof, and a surfactant. The invention also discloses a podophyllotoxin composition further comprising a targeting moiety. The present invention also discloses a method of delivering a podophyllotoxin, an analog thereof or a derivative thereof, to a cell by administering the described podophylootoxin compositions. Further, the present invention discloses a method of making the podophyllotoxin compositions.

Abstract: Pharmaceutical compositions are provided which comprise a lactone form of camptothecin, or a lactone form analog thereof that is effective for controlling abnormal cell proliferation; and at least one amphiphilic block copolymer that, upon oral administration to a patient, increases oral bioavailability of the lactone form significantly more than that of a directly related carboxylate form of the camptothecin or analog thereof. Compositions are also provided that further comprise at least one bioadhesive polymer that protects a closed alpha-hydroxy lactone structure of the lactone form of camptothecin or analog thereof, and provides a controlled release of the lactone form of camptothecin or lactone form analog thereof, in GI, upon oral administration to a patient. Methods are described for the prevention and/or treatment of a condition related to abnormal cell proliferation comprising orally administering to a patient in need of thereof an effective amount of a composition of the present invention.

Abstract: Compositions for delivery having a biological agent or derivative thereof, and a poly(oxyethylene)-poly(oxypropylene) block copolymer. The compositions are useful in immunodeficiency infection virus therapy. The invention also encompasses methods of treatment using the same.
