  • Publication number: 20200261583
    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.

  • Patent number: 8945627
    Abstract: The invention provides biocompatible micelles loaded with one or more active agents. The micelles can encapsulate anticancer drugs such as gossypol, and combinations of drugs, such as gossypol and paclitaxel, gossypol and 17-AAG, gossypol and cyclopamine, gossypol, paclitaxel, and 17-AAG, and gossypol, paclitaxel, and cyclopamine. The micelle compositions provide effective solubilization of difficult to solubilize drug combinations without the need for additional surfactants that can be toxic to patients. Thus, the invention provides stable and biocompatible drug formulations that improve bioavailability without causing toxicity.
