Methods and compositions useful for administration of chemotherapeutic agents
In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of a pharmaceutically active agent, wherein the agent is associated with a polymeric biocompatible material.
1 . A pharmaceutically acceptable formulation of paclitaxel for treatment of primary tumors in a human subject which achieves high local concentration of said paclitaxel at the tumor site, said formulation being substantially free of cremophor and comprising paclitaxel in a dose in the range of about 30 mg/m 2 to about 1000 mg/m 2 .
2 . The formulation of claim 1 , wherein said formulation is free of cremophor.
3 . The formulation of claim 1 further comprising one or more of albumin, a polyalkylene glycol, and an oil.
4 . The formulation of claim 1 , wherein said formulation is an emulsion containing an organic phase and an aqueous medium.
5 . The formulation of claim 4 , wherein the organic phase comprises an oil.
6 . The formulation of claim 5 , further comprising a synthetic polymer.
7 . The formulation of claim 6 , wherein said synthetic polymer is selected from the group consisting of linear polyalkylene glycols and branched chain polyalkylene glycols.
8 . The formulation of claim 5 , further comprising polyethylene glycol.
9 . The formulation of claim 8 , wherein substantially all of the paclitaxel is present in the organic phase.
