Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent).

The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered.

Abstract: The subject invention relates to compositions and methods useful for the in vivo delivery of substantially water-insoluble drugs, like taxol. The use of specific composition and preparation conditions enables the reproducible production of unusually water-soluble formulation, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a re-dispersible dry powder comprising nanoparticles of drug. The innovation is also based on the fact that complementary partner is also an active drug but may have a different mode action with respect to primary molecule of the hybrid drug. The complementary molecule has multiple properties like antioxidant, antimicrobial, anti-inflammatory, anti-allergic, cox-2 inhibitors, etc. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable.

Abstract: The invention provides a drug delivery system for a combination of therapeutic agents. The system includes a water soluble biodegradable ABA-type triblock copolymer that possesses thermosensitive gelation properties. The system can form a stable thermogel that includes a combination of therapeutic agents including, for example, rapamycin, paclitaxel, and 17-AAG. After administration to a subject, the drugs are released at a controlled rate from the thermogel, which biodegrades into non-toxic components. The polymer system can also function to increase the solubility and stability of drugs in the composition.
